Appendix O. Pretest Methods and Summary of Findings
Beginning July 19, Insight pretested the following instruments for the study of food security and well-being in Puerto Rico:
Household survey
In-depth interview protocol
Recruitment materials
The overarching objective of the pretest was to ensure the instruments were clear and understandable to respondents. Specific pretest objectives for both instruments follow:
Identify problems related to communicating intent or meaning of questions.
Determine whether respondents can accurately provide the information requested.
Evaluate the flow, question order, and respondent burden in terms of the number of questions and recall of difficult events such as natural disasters.
Ensure the Spanish translation conveys the intended meaning.
The survey pretest also aimed to—
Assess the response options for relevance and adequate range of response options.
Identify problems with introductions, instructions, or explanations.
Assess the cultural relevance of the questions.
Recruitment Methods
To identify potential pretest participants, we developed a recruitment announcement for distribution via social media by Estudios Técnicos and the Food Bank of Puerto Rico. The announcement included a point of contact and telephone number for a team member from Estudios Técnicos who screened callers for eligibility and scheduled the interviews.
We planned to complete nine pretest interviews for each data collection instrument, with a ratio of five NAP participants to four low-income nonparticipants. Within those two subgroups, we tried to recruit a mix of households with children and without children. Finally, for each instrument, we tried to identify two participants who could complete the pretest in English.
We developed a recruitment script with questions about age, household composition, income, and NAP participation status to determine each person’s subgroup status. We also asked about language preference to identify individuals who could complete the pretest in English.
Forty-seven individuals responded to the recruitment announcement. Of those, 39 were eligible and 8 were ineligible based on income or age. The recruiter scheduled appointments with eligible individuals, tracking each person’s NAP participation status and household composition to ensure all subgroups were represented. She also made reminder calls or sent reminder text messages to each pretest participant the day before the scheduled interview to confirm their appointment. Table 1 below shows the distribution of volunteers and completed interviews by subgroup.

Tables 2 and 3 show the distribution of pretest respondents by subgroup for the survey and in-depth interview instruments, respectively. Seven of the eight survey pretest interviews were conducted in person at Estudios Técnicos. The eighth pretest interview was conducted in person at the home of the pretest participant. This participant lived on the island’s west coast, where one of the pretest interviewers planned to be after completing the interviews in San Juan.
We originally planned to conduct all in-depth interviews in person. We started offering participants the option of participating via Zoom after several scheduled participants canceled their in-person appointment. Several factors contributed to these cancellations. A truckers’ strike resulted in long lines at gas stations and increased traffic as residents rushed to fill their gas tanks and stock up on necessities. A few pretest participants did not want to risk sitting in traffic or running out of gas while traveling to Estudios Técnicos. Other participants had a change in their work schedule or could not find childcare. Of the nine completed in-depth interview pretest interviews, four were conducted in person and five via Zoom.
It is worth noting that only four volunteers were non-NAP participants with children. We were not able to complete a survey pretest interview with anyone from this group, and the one in-depth interview we completed was via Zoom. There are several possible reasons this subgroup might have been particularly difficult to recruit. Widespread loss of work and income because of the pandemic has increased participation in NAP, thereby reducing the number of nonparticipating households that met our low-income threshold. Without NAP support, adults in these households may be working multiple jobs to support their families, leaving them with limited time to participate in the pretest. If economic circumstances at the time of data collection are similar to current circumstances, these findings point to possible challenges that could affect response rates among this critical subgroup. The study team will closely monitor response rates by subgroup during the field period and is currently considering strategies for bolstering participation rates among subgroups that are slow to respond.
Though we identified two volunteers who were able to complete the pretest in English (one survey respondent and one in-depth interview respondent), no one expressed a preference for English. Based on this finding, we expect most respondents will complete the survey in Spanish and request that the interview be conducted in Spanish.

Pretest Interviews for Survey Instrument
Two bilingual interviewers from Insight conducted eight pretest interviews using the “think-aloud” method. This method involves asking the participant to read each question aloud and verbalize their thought process as they read the response options and select their answer.
At the start of the pretest interview, the interviewer explained the purpose of the study and the aims of the pretest. She also reviewed the consent form, which stated that participants’ individual responses would not be shared with anyone outside the research team, but they might be reported in a memo in combination with other participants’ responses and without any personal identifiers to explain any recommendations for improving the data collection instruments. The consent form also described the respondents’ rights as research subjects and the voluntary nature of their participation, emphasizing that their decision to participate or not participate would not affect their NAP benefits. Finally, the interviewer asked the respondents’ permission to audiorecord the interview and asked for verbal consent to proceed with the interview. All respondents agreed to have the interview recorded.
Interviewers introduced the think-aloud method by engaging respondents in a practice exercise. To help the respondent get in the habit of narrating their thoughts as they formulate their answer to a question, the interviewer asked the participant to identify the number of windows in the place where they live. The interviewer encouraged the participant to envision the space, counting each window as they moved from one wall to another. Once participants finished this exercise, the interviewer asked them to begin the survey.
Survey Length
The duration of the survey pretest using the think-aloud method ranged between 80 and 115 minutes. No participants expressed complaints about the length of the survey. These volunteers were informed ahead of time that the pretest interview would take up to 90 minutes, including time to debrief and discuss specific survey items. One of the pretest interviewers identified two NAP participating volunteers who agreed to complete the survey without interruption. One volunteer completed the survey in 38 minutes. The second volunteer completed it in 45 minutes, for an average time of 41 minutes. It is possible randomly chosen households will be less willing to complete a survey of this length. For this reason, we have looked for opportunities to streamline the questionnaire.
General Issues/Impressions
Participants had little trouble completing the survey, and they had thoughtful suggestions regarding the response options. For example, when answering A.8., several participants suggested the list of food categories did not reflect the typical Puerto Rican diet. There were a few places where one or more respondents overlooked the instructions or a skip pattern. We will address this issue when designing the final print layout of the paper survey, but for now, we have added instructions in bold font, all caps.
Pretest participants did not refuse to answer any questions, and they did not consider any items to be especially sensitive. Two pretest respondents brought a child with them to the pretest interview. The interviewer skipped the food security module for those two participants based on concerns that the participants would not feel comfortable reading and answering aloud questions about skipping meals in front of their children. This concern should not be an issue during the data collection because sample members will have the option of responding to the survey privately via the web, on paper, or by phone.
Item-Level Findings and Recommendations
The table below lists questionnaire items, including those for which respondents reported difficulty or confusion or provided additional comments. The questions appear in numerical order for ease of reference. The table describes the nature of the problem and resulting changes.
Pretest Interviews for the In-Depth Interview Protocol
Interview Length
The in-depth interviews lasted between 58 and 100 minutes. With one exception, all pretest interviews took less than one hour. The longer interview was with a respondent who took a few brief breaks during the interview to collect her thoughts. We estimate the in-depth interviews will take no more than one hour.
General Issues or Impressions
Overall, results of the in-depth interviews indicated that the questions were clear, appropriate, and easily answered by participants. Based on feedback from interviewers and respondents, we recommend only minor revisions. Suggested revisions are summarized below.
Interviewers observed that the progression of questions helped ease participants into talking about potentially sensitive subjects, and they found participants to be forthcoming when asked about how they have coped with natural disasters and COVID-19. Some participants said no one had ever asked them about those experiences, and they found it worthwhile to reflect on what happened, how these experiences affected them, and how they coped. One participant was visibly upset when describing her experience of the earthquakes. The interviewer offered to take a break or stop the interview, but the participant wanted to continue. She was among those who thanked the interviewer for taking an interest in her story. These encounters have important implications for interviewer training, as described below.
Many participants considered their recent experiences of food security atypical, and they attributed their relative comfort with purchasing food to COVID-19 relief efforts. They were concerned, however, about how long those relief efforts might continue and how they would manage if NAP expanded benefits were discontinued.
Section-Level Findings and Recommendations
Section A. You and Your Household
Beginning the interview with questions about household composition worked well, as participants easily identified who lives with them. The questions provide an effective “ice breaker,” and the information gathered will help address research questions about hunger-coping strategies among intergenerational households.
Questions 1a and b elicited brief answers, but interviewers thought the questions were useful in getting participants warmed up to the interview process.
Section B. Community Food Needs
This brief section is intended to gain insight into the factors that contribute to low food security in a community (e.g., having money for food, getting to stores) and if particular households are more likely than others to experience low food security (e.g., single-parent households). Some responses reflected a desire to respect neighbors’ privacy; for example, several participants said they were not in other people’s business, so they did not know how to answer. Interviewers offered suggestions for rewording the questions to make it clear we are not asking anyone to identify specific people. As part of the interviewer training, we will discuss possible probes interviewers can use if a participant hesitates to answer. Rather than scripting these probes in advance, we will ask interviewers to offer suggestions in their own words and discuss their suggestions as a group. The purpose of the discussion will be to ensure all interviewers have a common understanding of what we hope to learn from the question and share ideas on how to encourage participants to talk openly about economic circumstances in their community.
Section C. Meeting Family Food Needs
Participants provided detailed information about their shopping habits, preferences, and strategies. In response to the question, “Are there any food stores or markets nearby that you don’t shop at?” a few people mentioned the Mercado Familiar. El Mercado Familiar (Family Market Program) is a collaboration between ADSEF and Puerto Rico’s Secretary of Agriculture intended to stimulate local food production and increase NAP participants’ consumption of fruits and vegetables. A few participants reported they no longer take advantage of the program because the hours are limited, the produce is expensive, and the portion of their NAP benefit they can use at these markets is not enough to purchase what they would need to feed their household.
In response to the question, “Have there been times recently when you did not have enough food or were worried about how to stretch your food dollars?” many participants said such worries were greatly reduced since they started receiving additional assistance as part of ongoing COVID-19 relief efforts. Participants said they frequently worried about having enough money for food prior to COVID-19, and they discussed strategies they used to stretch their food dollars, such as shopping for items in bulk or getting fruits or vegetables from neighbors with a garden.
Participants were uncertain how to answer the question, “What are the most important things that have helped you to get by during difficult times?” Some said they relied on their faith or felt motivated to be strong for their family, but they did not identify practical strategies that proved helpful. Participants found it easier to answer when the question followed a discussion about coping with disasters or COVID-19 (question 23). For this reason, we recommend deleting the question from section C.
Section D. Life Events and Coping With Challenges
Participants were very forthcoming with information when asked about their experience with natural disasters and COVID-19, and several said they appreciated the opportunity to talk about these topics. One participant was moved to tears as she recounted the traumas she experienced after the earthquakes. The interviewer asked the participant if she wished to take a break and offered to do some deep breathing exercises with her. With some brief breaks, the participant was able to complete the interview, and she thanked the interviewer for listening. She said she did not realize those experiences were still so fresh in her mind. When the study team debriefed after this interview, we discussed some implications for interviewer training. Specifically, we will train all interviewers on the use of trauma-informed interviewing skills and provide them with referral resources to ensure they are well prepared to handle similar situations.
Sections E and F. NAP
When asked how long their NAP benefits typically last, participants distinguished between pre- and post-COVID; as mentioned previously, participants said that pre-COVID it was difficult to make their benefits last a full month, but this situation started to change after the pandemic, when stimulus checks were issued and other support became more available.
When asked, “What are some reasons people might choose not to apply for NAP?” respondents were able to offer a few reasons, some based on stories they had heard about others’ experience with the application or eligibility determination process. For example, one participant said she has an elderly neighbor who was denied eligibility based on income, even though she spends a large proportion of her income on medicine. The participant noted that such stories discourage people from applying because they create a perception that the eligibility determination process is unfair, cryptic, or complicated.
Recruitment Materials
Pretest interviewers asked participants to read and comment on the survey invitation letter for the area probability survey. There are a few minor differences between this letter and the letter that will be mailed with the paper survey to sample members from the NAP participant list. Because sample members from the NAP participant list will receive an initial invitation to complete a web-based version of the survey, the letter that accompanies the mail survey will not be the first piece of correspondence they receive. They will receive the initial web invitation letter and a reminder postcard before the mail survey, so the letter that accompanies the mail survey references these prior mailings.
The letter that accompanies the area probability survey is the first and only letter these sample members will receive. To simplify pretest procedures, we chose to test this version of the cover letter. After completing the think-aloud pretest interview and debriefing with the interviewer, participants were given a copy of the invitation letter. The interviewer asked each participant to read the letter aloud and ask any questions. Participants said the letter was clear, and they understood what it was asking them to do. One suggestion offered was to use a different Spanish phrase for postage-paid envelope.
