Ecodevelopmental theory is a theoretical framework used to explain the interplay among risk and protective processes associated with HIV risk behaviors among adolescents. Although ecodevelopmentally based
interventions have been found to be efficacious in preventing HIV risk behaviors among Hispanic youth, this
theory has not yet been directly empirically tested through a basic research study in this population. The
purpose of this cross-sectional study was to empirically evaluate an ecodevelopmentally based model using
structural equation modeling, with substance use and early sex initiation as the two outcomes of the ecodevelopmental chain of relationships. The sample consisted of 586 Hispanic youth (M age = 13.6; SD = 0.75)
and their primary caregivers living in Miami, Florida. Adolescent, parent, and teacher reports were used. The
results provided strong support for the theoretical model. More specifically, the parent–adolescent acculturation gap is indirectly related both to early sex initiation and to adolescent substance use through family
functioning, academic functioning, perceived peer sexual behavior, and perceived peer substance use.
Additionally, parent’s U.S. orientation is associated with adolescent substance use and adolescent sex initiation through social support for parents, parental stressors, family functioning, academic functioning, and
perceived peer sexual behavior and substance use. These findings suggest that HIV risk behaviors may best
be understood as associated with multiple and interrelated ecological determinants.

in 1990 to 15% in 2007 (Bernstein, 2008). Hispanics have accounted for nearly half
of all U.S. population growth since 2000 and are expected to comprise 25% of all
Americans by 2050 (Bernstein, 2008). Hispanics are also a young population, with
nearly 40% under age 20 (Ramirez & de la Cruz, 2003).
Along with their large and rapidly increasing numbers, Hispanic adolescents in the
United States are at higher risk for substance use (including alcohol, cigarette, and
illicit drug use) than either non-Hispanic White or non-Hispanic Black adolescents
(Johnston, O’Malley, Bachman, & Schulenberg, 2008). Furthermore, Hispanic adolescents report engaging in sexual intercourse earlier than do non-Hispanic Whites
(although not earlier than non-Hispanic Blacks), and they have the lowest condom use
rates of any U.S. ethnic group (Centers for Disease Control and Prevention, 2006).
Preventing substance use and delaying the onset of sexual activity is important given
that both substance use and early sexual activity are associated with HIV infection
(Prado et al., 2006). In summary, although the national statistics are alarming for all
youth, what may be even more disconcerting is that Hispanic youth, the largest and
fastest growing demographic group in the United States (Ramirez & de la Cruz, 2003),
appear to be at heightened risk for early engagement in severely health compromising
behaviors. Preventing these HIV risk behaviors in this population is, therefore, an
urgent public health issue.
To prevent both substance use and early sexual behavior initiation among Hispanic
youth, it is important to understand the social-contextual processes associated with
these behaviors. Therefore, the purpose of this cross-sectional study was to empirically
evaluate an ecodevelopmental based model with substance use and early sex initiation
as the two outcomes of the ecological/ecodevelopmental chain of relationships. This
study contributes to the literature by examining the indirect effects among these processes as well as by evaluating the direct effects in a single comprehensive model.
Although many of these direct effects have been examined in prior research, this study
is one of the first to examine them within a comprehensive model in which indirect
effects can also be investigated. These findings may then be used as a springboard for
future longitudinal studies further ascertaining the contextual predictors of substance
use and sexual risk taking in Hispanic adolescents.
ECODEVELOPMENTAL THEORY: ECOLOGICAL
PREDICTORS OF HIV RISK BEHAVIOR
Adolescent health risk behaviors, including substance use and early sex initiation,
are influenced by a number of risk and protective processes. Risk and protective processes that have been identified as correlates of adolescent problem behaviors include
(but are not limited to) positive parent–adolescent communication; poor bonding to
family; academic failure; lack of commitment to school; and peer rejection (Lopez
et al., in press; Prado et al., 2009). Research has documented that difficulties in several
different domains of functioning interact to increase the likelihood of substance use and
early sex initiation (Dishion, Nelson, & Bullock, 2004; Hawkins, Catalano, & Miller,
1992). Studying risk and protective processes independently provides an incomplete
picture and carries the danger of overestimating the effects of a single risk and protective process when examined in isolation from other simultaneously operating risk and
protective processes (Magnusson & Casaer, 1993; Thornberry, 1994). Rather, individual risk and protective processes work together, often influencing one another—
and some risk and protective processes affect the target behavior indirectly through

other risk processes (Prado et al., 2009; Szapocznik & Coatsworth, 1999). Such mediational sequences can be examined only by studying risk and protection as an integrated
developmental process (Schwartz, Pantin, Coatsworth, & Szapocznik, 2007). The complexity of the determinants of substance use and early sex initiation requires that these
behaviors be understood as multidetermined phenomena, with multiple and interrelated
processes contributing to their development (Prado et al., 2009). Ecodevelopmental
models (e.g., Pantin, Schwartz, Sullivan, Prado, & Szapocznik, 2004) focus on the
multiple social contexts influencing development, the interrelations between those contexts, and how these elements affect risk for the development of drug use and unsafe
sexual behaviors in adolescents (Cicchetti & Rogosch, 2002).
In our construction of ecodevelopmental theory (Pantin et al., 2004), we have incorporated three primary, integrated elements. We focus on two of these in this study: (a)
social ecological theory and (b) an emphasis on interplay and sequencing among socialcontextual processes. The social-ecological component of ecodevelopmental theory is
drawn from Bronfenbrenner’s work on the social ecology of human development
(Bronfenbrenner, 1979, 1986). Bronfenbrenner has organized the multiple influences
on adolescent development according to their proximity to the adolescent, presented
here from furthest to closest: macrosystems (the broad social and philosophical ideals
that define a particular culture, such as culture and acculturation1), exosystems (contexts in which the adolescent does not participate directly but that impact the functioning of important members of the adolescent’s life, such as parents’ support systems),
mesosystems (contexts comprised of the interactions between important members of
the different contexts in which the adolescent participates directly, such as parental
monitoring of peers), and microsystems (contexts in which the adolescent participates
directly, such as the family).
The social-interactional component of ecodevelopmental theory holds that risk and
protection are expressed in the patterns of relationships and direct transactions between
individuals and processes within and across levels of context (Pantin et al., 2004). For
example, the amount of social support experienced by parents is directly predictive of
the harshness or supportiveness in their parenting (Swick & Broadway, 1997), which in
turn may affect the likelihood of adolescent drug use and unsafe sexual behavior
(Broman, Reckase, & Freedman-Doan, 2006; Roche, Ahmed, & Blum, 2008). Table 1
lists the variables that we are using within each level of context.
Cultural processes, such as the parent’s own acculturation and the mismatch between
parent and adolescent U.S. and Hispanic orientations (i.e., parent–adolescent acculturation gap) are central to ecodevelopmental theory (Prado et al., 2008). Ecodevelopmental
theory holds that cultural processes, such as parents’ lack of familiarity with U.S. culture
and the resulting parent–adolescent acculturation gap, produce a trickle-down effect by
contributing to exosystemic problems such as parental isolation, which in turn may cut
parents off from their adolescents’ peer networks (i.e., mesosystemic problems). For
example, according to some investigators, differential acculturation promotes risk for
drug use and HIV risk behaviors in Hispanic immigrant adolescents because it creates
additional familial conflict that undermines adolescent bonding to the family and erodes
parental authority (Martinez, 2006). For example, parents may perceive their adolescents’
“Americanized” behaviors as disrespectful to the family and may try to reassert their
authority in hopes of regaining control. In turn, the overly restrictive and controlling parenting style is likely to produce rebellion in the adolescent (Bean, Barber, & Crane, 2006)
and to result in deterioration of the family–child relationship.

Figure 1. Hypothesized ecodevelopmental model in predicting HIV risk behaviors.
The purpose of this study was to begin to empirically evaluate the trickle-down
process of acculturation and parent–adolescent acculturation gap, with substance use
and early sex initiation posited as outcomes of this ecological/ecodevelopmental chain
of relationships (see Figure 1). Figure 1 displays all of the direct contextual relationships that will be examined as part of the hypothesized model. Support for all of the
contextual relationships hypothesized in Figure 1 has been obtained in prior research
(Henry, Schoeny, Deptula, & Slavick, 2007; Lopez et al., in press; Martinez, 2006) or
has been suggested by clinical literature (Pantin et al., 2004). For example, differences
in acculturation between Hispanic parents and adolescents may compromise the
parent–adolescent relationship and the family system as a whole (Martinez, 2006).
For another example, parents who are close to their adolescents (positive family functioning) may be more likely to monitor them (Dishion, Poulin, & Skaggs, 2000) and to
be involved in their schoolwork (Lopez et al., in press).
As part of testing the trickle-down effect within ecodevelopmental theory, we
hypothesize three indirect paths in addition to the direct paths presented in Figure 1.

Prado et al. / Predicting HIV Risk Behaviors 103
First, we hypothesize that macrosystemic processes (parental acculturation and parent–
adolescent acculturation gap) will influence both substance use and early sex initiation
through family functioning, school functioning, perceived peer sexual behavior, and
perceived peer substance use. Additionally, we hypothesize that parent’s level of acculturation will be indirectly associated with both adolescent substance use and early
sexual behavior initiation through parental stressors, social support for parents, family
functioning, school functioning, perceived peer sexual behavior, and perceived peer
substance use. This study contributes to the literature by examining the indirect effects
of these processes as well as by evaluating these direct effects in a single comprehensive model, where indirect (mediated) effects can also be examined.
METHOD
Recruitment
Adolescent participants were recruited from one of four predominantly Hispanic
middle schools in Miami-Dade County, Florida. The four schools were selected
because they were in an urban, highly Hispanic neighborhood of Miami. Recruitment
of participants occurred through (a) the distribution of recruitment flyers to students
or (b) school counselor referral. Of the 730 eligible participants, 144 refused to participate. Hence, the response rate was 80.3%.
Participants
Participants were 586 Hispanic youth (55.3% male, 44.7% female; M age = 13.6
years, SD = 0.75) and their primary caregivers (13% male, 87% female; M = 41.0 years,
SD = 6.3). Of the adolescents, 46% were born in the United States, whereas all of the
parents were immigrants (as per the study’s inclusion/exclusion criteria). Immigrant
adolescents were born primarily in Cuba (33.8%), Nicaragua (23.6%), and Honduras
(13.7%). Of foreign-born adolescents, 43.45% had been living in the United States for
fewer than 3 years, whereas the rest had either been living in the United States between
3 and 10 years (n = 123; 39.30%) or more than 10 years (n = 54; 17.25%). Participants
were primarily from low-income families, with only 15.2% of the families’ reporting
household incomes greater than $30,000 per year.
Measures
Parents and adolescents completed the assessment battery in the language of their
choice (i.e., Spanish or English). All measures were translated into Spanish by integrating back translation and committee resolution approaches, as recommended (Szapocznik
& Kurtines, 1995). Of the adolescents, 59% completed their assessments in English,
whereas all parents completed their assessments in Spanish.
The measures section is organized into six subsections. The first section refers to
demographic variables and the last subsection refers to HIV risk behaviors (lifetime
substance use and lifetime sexual behavior subsections, respectively). The remaining
four sections were organized around the systems of ecodevelopmental theory: macrosystem, ecosystem, mesosystem, and microsystem. Table 1 includes a sample item and
the answer categories for each of the constructs measured in the study.

104 Health Education & Behavior (February 2010)
Demographics were assessed using a 10-item (adolescents) and 26-item form (parents), on which adolescents and parents provided their date and country of birth and
number of years living in the United States. Parents were also asked about their marital
status, years of education completed, and family income.
Macrosystemic cultural processes were measured by the parents’ U.S. orientation and
by the difference between the parents’ and adolescents’ U.S. orientation (i.e., parent–adolescent U.S. orientation gap). The Bicultural Involvement Questionnaire–Revised (Birman,
1998) was used to assess adolescents’ and parents’ level of orientation toward American
culture in terms of both (a) comfort and enjoyment with American cultural practices (e.g.,
comfort and use of language, food, and traditions) and (b) how much participants would
want or like to use American cultural practices. Of the 21 U.S. orientation items, 20 (all
except language use at work) were used for adolescents, and 20 of the 21 U.S. orientation
items (all except language use at school) were used for parents. Cronbach’s a estimates for
the U.S. orientation scores were .92 and .93 for adolescents and parents, respectively. The
parent–adolescent U.S. orientation gap score was computed by subtracting the parent’s
U.S. orientation score from the adolescent’s U.S. orientation score.
Exosystemic processes were operationalized as social support for parents and parental stressors. These variables were measured using the Social Provisions Scale (Russell,
Cutrona, Rose, & Yurko, 1984) and the Hispanic Stress Inventory (Cervantes, Padilla,
& Salgado de Snyder, 1991), respectively. The 24-item Social Provisions Scale assesses
five domains of social support: guidance, reliable alliance, reassurance of worth, attachment, and social integration. Cronbach’s a for the social support scale is .85. The
occupation/economic stressors subscale (13 items) and the immigration stressors subscale (18 items) from the Hispanic Stress Inventory were used to assess the parent’s
degree of extrafamilial stress. Parents were asked to indicate whether, in the past 6
months, they had experienced a number of occupational/economic stressors (e.g., they
think their income has not been sufficient to support their family or themselves) and
immigration stressors (e.g., they felt unaccepted by others because of their Hispanic
culture). Cronbach’s a estimates for the parental occupational/economic stress and
immigration stress subscale scores were .76 and .79, respectively. A parental stress scale
was derived by summing the occupational/economic and the immigration stress subscales. Cronbach’s a for this total parental stress score was .78.
Mesosystemic processes were operationalized as parental involvement in school and
parental monitoring of peers. Parents’ involvement in schoolwork was assessed using
one item from the Parenting Practices Scale (Gorman-Smith, Tolan, Zelli, & Huesmann,
1996), asking how often they check how their adolescents are doing at school. Parental
monitoring of peers (6 items) was measured using the Parent Relationship With Peer
Group Scale (Pantin, 1996), which asks adolescents to indicate the extent to which
(a) their parents know their friends, (b) their parents know the parents of their child’s
friends, and (c) their parents know what their child is doing when he or she is with her
or his friends. Cronbach’s a for the parental monitoring of peers subscale was .86.
Microsystemic processes were measured in four domains: (a) family functioning,
(b) school functioning, (c) perceived peer substance use, and (d) perceived peer sexual
behavior. Family functioning was assessed using adolescent reports of four indicators: parental involvement, positive parenting, family communication, and parentadolescent communication. Although both parents and adolescents reported on the
level of family functioning, in our prior work we have found that parent report and
adolescent reports of these family functioning indicators do not correlate highly (e.g.,
Schwartz, Pantin, Prado, Sullivan, & Szapocznik, 2005). Consequently, we used only
adolescent reports of family functioning. Parental involvement (11 items, a = .93)
Downloaded from http://heb.sagepub.com at UNIV OF MIAMI on February 4, 2010
Prado et al. / Predicting HIV Risk Behaviors 105
and positive parenting (6 items, a = .94) were assessed using the corresponding subscales from the Parenting Practices Scale (Gorman-Smith et al., 1996). Family communication (3 items, a = .75) was assessed using the corresponding subscale from the
Family Relations Scale (Tolan, Gorman-Smith, Huesmann, & Zelli, 1997). Parent–
adolescent communication (20 items, a = .88) was assessed using the Parent–
Adolescent Communication Scale (Barnes & Olson, 1985).
School functioning was assessed using conduct, academic, and absent and tardy
reports from teachers as well as two adolescent-reported items and one parent-reported
item. Teachers rated the adolescent’s conduct, academic performance, absent and tardy
through quarterly report cards for each class in which the student was enrolled. Academic
and conduct grades were measured on a 5-point scale (A = 4, B = 3, C = 2, D = 1,
F = 0). Adolescent reports of school functioning problems were gathered using two
items (“I disobey at school” and “My school work is poor”) from the Youth Self Report
(Achenbach, Dumenci, & Rescorla, 2002). On the Youth Self Report, adolescents
responded on a 3-point Likert-type scale ranging from 0 = not true to 2 = very true or
often true. Cronbach’s a for responses to these two items was .78. Parent reports of
their adolescent’s school functioning were assessed using one item from the Revised
Behavior Problem Checklist (Quay & Peterson, 1993). Parents indicated the extent to
which their child’s “school work is messy, sloppy.” Responses were rated on a 3-point
scale (0 = no problem, 1 = mild problem, 2 = severe problem).
Perceived peer substance use (three items, a = .80) was measured using adapted
substance use items from the Monitoring the Future Survey (Johnston et al., 2008). The
substance use items were adapted by replacing “have you” with “how many of your
friends have.” Adolescents were asked how many of their friends have ever smoked
cigarettes, used alcohol or any illegal drug in their lifetime. Similarly, perceived peer
sexual behavior was assessed using one item from the Interview for Situations of Sexual
Possibility (Paikoff, Parfenoff, Williams, & McCormick, 1997). Adolescents indicated
whether, in a private place, their friends have had sexual intercourse with one another.
HIV risk behaviors were measured in terms of adolescent lifetime substance use
(alcohol, cigarette, or illicit drug use) and early sex initiation. Adolescent substance use
(three items; a = .64) was assessed using items similar to those used in the Monitoring
the Future Study, a national epidemiologic study to assess the prevalence of substance
use in the United States (Johnston et al., 2008). The adolescents were asked whether
they had ever smoked, drank alcohol, or used an illicit drug. Lifetime sexual behavior
(three items; a = .99) was assessed using the Sexual Behavior Instrument (Jemmott,
Jemmott, & Fong, 1998). Adolescents were asked to indicate whether they had ever had
oral, vaginal, or anal intercourse.
Data Analytic Plan
The test of the study hypotheses proceeded in three steps. First, measurement models were estimated to ascertain the feasibility of collapsing multiple indicators of family
functioning, school functioning, and parental social support into single latent variables
(all other variables were measured using observed variables). This was done by conducting confirmatory factor analyses (CFA) using Mplus version 5.1 (Muthén &
Muthén, 1998-2006). Second, we estimated the hypothesized structural equation model
(see Figure 1). The fit of the model was evaluated primarily in terms of the comparative
fit index (CFI), which compares the hypothesized model to a null model with no paths
or latent variables, and the root mean square error of approximation (RMSEA), which
estimates the extent to which the covariance matrix specified in the model deviates
Downloaded from http://heb.sagepub.com at UNIV OF MIAMI on February 4, 2010
106 Health Education & Behavior (February 2010)
from the covariance matrix observed in the data. The chi-square statistic is reported but
is not used in the interpretation, given that it tests the null hypothesis of perfect fit to
the data—which is nearly always false (Preacher, Cai, & MacCallum, 2007). CFI values of .95 or greater and RMSEA values of .06 or less are indicative of good model fit
(Byrne, 2001). Third, the asymmetric distribution of products test (MacKinnon,
Lockwood, Hoffman, West, & Sheets, 2002) was used to evaluate each of the hypothesized mediational relationships. This test is based on the sampling distribution of the
product of the paths that comprise the hypothesized mediating pathway. If the confidence interval for this product does not include 0, then partial mediation is assumed.
This method is more statistically powerful (MacKinnon, Fritz, Williams, & Lockwood,
2007) than more traditional methods of testing for mediation.
RESULTS
Measurement Models
Family Functioning. A CFA indicated that all four indicators of family functioning
loaded significantly onto a single latent construct. The loadings were .74, .59, .69,
and.69 for parent–adolescent communication, parent involvement, positive parenting,
and family communication, respectively. Because the model was saturated (i.e., had 0
degrees of freedom), fit statistics are not reported.
School Functioning. Seven indicators (four teacher reported, two adolescent reported,
and one parent reported) were included in this measurement model. The model provided a good fit to the data, c2(3) = 5.03, p = .17; CFI = .99; RMSEA = .034. All seven
indicators loaded significantly onto a single latent construct. These loadings ranged
from .30 to .66.
Parental Social Support. Five indicators (guidance, reassurance of worth, social
integration, attachment, and reliable alliance) were included in this measurement
model. The model provided a good fit to the data, c2(4) = 13.1, p = .01; CFI = .99;
RMSEA = .06. All seven indicators loaded significantly onto a single latent construct.
These loadings ranged from .71 to .85.
Structural Equation Model—Hypothesized Model
Overall, the hypothesized model depicted in Figure 1 provided an adequate fit to the
data, c2(89) = 194.0, p < .01; CFI = .93; RMSEA = .05. The results for each of the
hypothesized relationships are reported below. Only significant direct effects are shown
in Figure 2.
Direct Effects: Macrosystemic Processes to Exosystemic Processes. Parent’s
U.S. orientation was inversely and significantly related to social support for parents
(b = –.16, p < .01) and to parental stressors (b = –.17, p < .01).
Macrosystemic Processes to Microsystemic Processes. Both parents’ U.S. orientation (b = –.44, p < .001) and differential parent-adolescent U.S. orientation (b = –.24,
p < .001) were inversely related to family functioning.

Mesosystemic Processes to Microsystemtic Processes. Both parental school involvement (b = .43, p < .001) and parental monitoring of peers (b = .36, p < .001) were
positively associated with family functioning. Surprisingly, parental school involvement was not significantly related to school functioning. Parental monitoring of peers

108 Health Education & Behavior (February 2010)
was also not significantly related to perceived peer substance use and perceived peer
sexual behavior.
Microsystemic Processes to HIV Risk Behaviors. Perceived peer substance use was
positively related with adolescent substance use (b = .58, p < .001). Perceived peer
sexual behavior was positively related with early sex initiation (b = .51, p < .001). We
did not observe significant direct effects from family functioning and school functioning to either adolescent substance use or early sex initiation.
Relationships Between Microsystemic Processes. Family functioning was positively
related with school functioning (b = .87, p < .001), and school functioning was
inversely related with perceived peer substance use (b = –.61, p < .001) and perceived
peer sexual behavior (b = –.71, p < .001).
Indirect Effects. Four indirect effects between macrosystemic processes and each of
the two HIV risk behaviors were tested and found to be significant. The results showed
that parent’s U.S. orientation and early sex initiation use were indirectly related through
parental stressors, social support for parents, family functioning, school functioning,
and perceived peer sexual behavior (point estimate, b = –.004, p < .05; 95% CI: [–0.001
to –0.0001]). Similarly, parent’s U.S. orientation and adolescent substance use were
indirectly related through parental stressors, social support for parents, family functioning, school functioning, and perceived peer substance use (point estimate: b = –.004;
p < .05. 95% CI: [–0.001 to –0.0001]). Additionally, differential parent–adolescent
U.S. orientation and early sex initiation were significantly related through family
functioning, school functioning, and perceived peer sexual behavior (point estimate:
b = .008; p < .05; 95% CI: [0.002 to 0.014]). Similarly, differential parent–adolescent
U.S. orientation and adolescent substance use were significantly related through family functioning, school functioning, and perceived peer substance use (point estimate:
b = .007; p < .01; 95% CI: [0.003 to 0.012]).
Post Hoc Analyses
To examine whether the observed association vary across gender and nativity status
(i.e., U.S. born vs. foreign born), in post hoc analyses, we tested for model invariance
by both gender and nativity status (U.S.-born versus immigrant). To test for invariance
by gender, we estimated two models: (a) a model with the paths unconstrained across
genders and (b) a model with the paths constrained across both genders. To examine the
difference between these two models, we used the difference in chi-square test using
the “DIFFTEST” function in Mplus. We found that the difference in chi-square between
the constrained and the unconstrained model was nonsignificant, Dc2(16) = 12.64,
p = .70. This implies that the model fits equally across gender. Similarly, for nativity
status, we found that the difference in chi-square between the constrained and the
unconstrained model was nonsignificant, Dc2(17) = 21.14, p = .22. This implies that the
model fits equivalently across U.S.-born and immigrant adolescents.
DISCUSSION
The objective of this study was to empirically evaluate ecodevelopmental theory
and more specifically to test the trickle-down effect within ecodevelopmental theory.

Ecodevelopmental theory is a theoretical framework used to explain the interplay among
the risk and protective processes associated with substance use and early sexual behavior
initiation among Hispanic adolescents. The results from this study support the hypothesized model and trickle-down effects of the theory. First, parent adolescent acculturation gap was indirectly related to both early sex initiation and adolescent substance use
through family functioning, academic functioning, perceived peer sexual behavior, and
perceived peer substance use. Similarly, parents’ level of acculturation was associated
with adolescent substance use and sex initiation and adolescent through social support for
parents, parental stressors, family functioning, academic functioning, and perceived peer
sexual behavior and substance use. Thus, the trickle-down effects of ecodevelopmental
theory were supported. This suggests that macrosystemic processes can influence behavioral health outcomes—such as substance use and early sexual behavior—through their
associations with exosystemic, mesosystemic, and microsystemic processes. From a prevention science perspective, it may be suggested that preventive interventions targeting
macrosystemic processes can have an effect on behavioral health through the indirect
effects that macrosystemic processes may have on other, more proximal systemic processes. For example, Szapocznik and colleagues (1986) demonstrated that targeting cultural orientations (a macrosystemic process) could produce effects on behavioral health
outcomes. In that study, the intervention used cultural orientations as a means of changing
family functioning, which consequently had an effect on adolescent conduct problems.
In terms of the direct effects examined, the results of the model support the existing
empirical and/or clinical literatures. For example, the finding that parent’s U.S. orientation was inversely associated with parental stress is consistent with previous studies
(Scribner, 1996; Turner, Lloyd, & Taylor, 2006). Additionally, parent’s U.S. orientation
was inversely related with social support for parents. Thus, U.S. orientation may also
be related to stress for parents, such that becoming more “American”—and perhaps
beginning to relinquish their Hispanic culture—may be associated with greater levels
of stress and a smaller social support network.
Another important finding is that differential acculturation was inversely related to
family functioning. Differential acculturation promotes risk for substance use and other
problem behaviors in Hispanic immigrant adolescents because it creates additional
familial conflict that undermines adolescent bonding to the family and erodes parental
authority (Martinez, 2006). The finding is consistent with recent work conducted in
Oregon using a sample of relatively recent Hispanic immigrants. In that study, Martinez
(2006) found a significant relationship between differential acculturation and likelihood
of adolescent substance use.
The finding that parental monitoring of peers was not related with either adolescent
substance use or sexual behavior initiation was unexpected and contrary to what others
have found (Borawski, Ievers-Landis, Lovegreen, & Trapl, 2003; Voisin, DiClemente,
Salazar, Crosby, & Yarber, 2006). In this study, the lack of relationship between parental
monitoring of peers and both substance use and early sex initiation may be explained
by the fact that monitoring has been conceptualized as a component of family functioning (Dishion & McMahon, 1998); including family functioning in the model may have
attenuated the association between parental monitoring and adolescent outcomes.
Study Limitations and Strengths
These results should be interpreted in light of several important limitations. First,
this study used a cross-sectional design, and the role of the ecodevelopmental processes
on substance use and early sex initiation were not examined over time. As a result, no
Downloaded from http://heb.sagepub.com at UNIV OF MIAMI on February 4, 2010
110 Health Education & Behavior (February 2010)
causal or directional inferences can be drawn from the results. It is important, therefore,
to replicate these results longitudinally. A related limitation to the cross-sectional nature
of the study is that we were not able to examine the developmental element of ecodevelopmental theory. As a result, we were able to test only the social-ecological component of ecodevelopmental theory. However, these results may provide a springboard for
longitudinal research that may test the theory more fully.
A second limitation involves the sole reliance on self-report measures. Independent
reports of family connectedness and parental involvement (e.g., observational tasks)
and of HIV risk behaviors (e.g., biological assays for substance use) were not available.
Although self-reports tend to converge reasonably well with biomarkers of drug use in
minority adolescents (Dillon, Turner, Robbins, & Szapocznik, 2005), there is evidence
that some adolescents provide false negative reports of drug use (Santisteban et al.,
2003). However, prior research (e.g., Metzger et al., 2000) has found that A-CASI, the
method of administration used in this study, increases the veracity of responding. Finally,
some adolescents may not be aware that they have a sexually transmitted disease, and
those who are aware may not be willing to disclose this information. Nonetheless, significant findings—consistent with theory—emerged despite the possibility of false
negative reports of drug use and sexually transmitted diseases.
A third limitation is that both peer substance use and adolescent substance use were
reported solely by the adolescent. Consequently, it is possible that the association
between (perceived) peer substance use and adolescent substance use may have been
inflated by the tendency for adolescents to assume that they and their peers are engaging
in similar degrees of substance use (Bauman et al., 2001; Prinstein & Wang, 2005). A
fourth limitation is that only one item was available to assess the parent–school mesosystemic construct (i.e., parents’ involvement in schoolwork). Future research should
replicate these findings with a validated scale of parents’ involvement in schoolwork. A
final limitation is that very specific constructs were used to assess the systemic processes
associated with ecodevelopmental theory. That is, given the breadth of ecodevelopmental theory as a whole, it may be possible to choose different variables at each level, and
we do not know how this might affect the results. For example, parental documentation
status is an important macrosystemic process that may contribute to parental stress and
other mesosystemic processes. However, our constructs and measures were selected
specifically to test the trickle-down, U.S.-orientation hypotheses within ecodevelopmental theory. These issues notwithstanding, the pattern of results that we obtained is consistent with theory and with past research using well-validated measures.
Conclusions and Practical Implications
Ecodevelopmental theory is a theoretical framework used to explain the interplay
among risk and protective processes associated with HIV risk behaviors among adolescents. This study provides some support for the theoretical model, and from an intervention
development perspective, these results may suggest that interventions targeting reductions in substance use, early sex initiation, and other HIV risk behaviors may benefit
from an ecodevelopmental approach. Ecodevelopmental principles have been applied
successfully to adolescent substance use and HIV preventive interventions across ethnic groups (Ialongo et al., 1999), including with Hispanic adolescents (Prado et al.,
2007). The utility of the ecodevelopmental interventions may also hold promise for
preventing other behavioral health problems, such as obesity. The present findings
may have implications for public health practitioners who may be interested in developing social-behavioral interventions to prevent or reduce HIV risk behavior and other
Downloaded from http://heb.sagepub.com at UNIV OF MIAMI on February 4, 2010
Prado et al. / Predicting HIV Risk Behaviors 111
health outcomes. For example, the findings from this study suggest that attending to
cultural processes such as parents’ U.S. orientation and the parent–adolescent acculturation gap may prevent adolescent substance use and early sexual behavior initiation. As such, public health practitioners may need to attend to these cultural processes
when developing or delivering interventions for Hispanic youth and their families
(Prado et al., 2008). Alternatively, promoting positive parent–adolescent relationships
may prevent the negative consequences that are often associated with a parent–adolescent acculturation gap. To the extent to which health outcomes can be linked to ecosystemic processes—and especially to chains of associations among processes at
different systemic levels—ecodevelopmentally based interventions may be especially
valuable in preventing these outcomes.
Finally, it is important for health educators to appreciate the cultural, occupational,
and education-related stressors on parents. In efforts to prevent adolescent substance
use and HIV risk behavior, it is essential to provide support resources (e.g., job placements, mental health services) for parents so that they are more able to focus on their
adolescents. Parents should also be helped to monitor the adolescent’s schoolwork and
peer activities (Pantin et al., 2004). Moreover, family-based strategies for promoting
effective communication, positive involvement, and support within the family are
essential to the health of Hispanic adolescents (Prado et al., 2007).
Note
1. Acculturation refers to the process of adaptation that occurs when two cultures come into contact
(Redfield, 1936). It has been most often used with reference to immigrants and their descendants (see Berry,
Phinney, Sam, & Vedder, 2006; Chun, Balls-Organista, & Marin, 2003, for collections of reviews). In this
study, acculturation is defined as orientation toward the American culture.
