Supporting Statement Part B - 6-14-2011

B. Statistical Methods (used for collection of information employing statistical methods)

1. Respondent Universe and Sampling Methods

1. Full-scale Study

Programs will be selected using stratified random sampling procedures. The only stratification variable will be four geographic region designated by the U.S. Census: Northeast, Midwest, South, and West. Three territories will be included – District of Columbia, Puerto Rico, and Guam – because they each have all three DD Network programs. District of Columbia and Puerto Rico will be included in Region 3 (South). Guam is included in Region 4 (West) for sampling

Table B-1 below shows the individuals that will be interviewed within each selected program.

2. ADD Assessment

The ADD assessment consists of interviews with ADD staff and stakeholders. Representatives from the following groups will be interviewed:

• ADD staff

• Federal disability partners

• National disability organizations

• Projects of National Significance

• Executive Directors from all DD Network programs in each state and territory

The ADD Commissioner and all ADD program staff and management were interviewed. The contractor worked with the ADD Commissioner, Deputy Commissioner, and Project Officer of the contract to identify appropriate individuals in Federal disability-related agencies and National disability organizations (thus, no sampling). Up to 9 individuals will be interviewed in each group. Projects of National Significance were grouped into categories (Emergency Preparedness; Family Support and Community Access Demonstrations; National Autism Resource and Information Center; Voting Project; Family Support 360; Youth Information, Training, and Resource Center; Ongoing Data Collection). Two projects were sampled from Family Support 360 and one project was sampled from each of the remaining categories. The project director of each selected project will be contacted for an interview.

All Executive Directors (180) will be requested to complete a web-based survey, so there will be no sampling for this group.

2. Procedures for the Collection of Information

1. Full-scale study

Data was collected using semi-structured interview guides to interview key informants identified with the help of Executive Directors of each program. Interviews were transcribed and summarized.

Analysis will consist of examining both quantitative and qualitative data collected on the 60 programs in 20 states and summarizing findings regarding structural, process, output and outcome indicators for each program and collaboration among the three programs. The focus of data analysis and synthesis will be on the extent to which DD Network programs are achieving outcomes. However, the contractor will also examine inputs, processes, and outputs to determine some of the factors that may contribute to falling short of achieving these outcomes and the factors that may be facilitating their achievement.

Analysis of in-person interview data, telephone interviews, materials obtained from programs will be qualitative. Data from the self-administered questionnaires are both quantitative and qualitative. In either case, a descriptive analysis, focusing on the research questions (Exhibit B-1) will take place.

Exhibit B-1. Research questions for the full-scale study

Structural Indicator questions:

1. What are the typical structural elements that enable and/or impede the individual entities of the DD Network (e.g., State Council, P&A, and UCEDD) to engage in activities that help meet the purpose and principles of the DD Act?

2. What are the typical structural elements that enable and/or impede the collaborative activities of the State DD Networks that support achievement of the DD Act purpose and principles?

Process Indicator questions:

1. What are the typical activities of the DD Network programs (e.g., State Council, P&A, and UCEDD) that contribute to achievement of the purpose and principles of the DD Act?

2. What are the typical collaborative activities of the State DD Networks that support achievement of the purpose and principles of the DD Act?

Output Indicator questions:

1. What are the typical immediate results of the activities of the DD Network programs (e.g., State Council, P&A, and UCEDD) that contribute to achievement of the purpose and principles of the DD Act?

2. What are the typical immediate results of the collaborative activities of the State DD Networks that support achievement of the DD Act purpose and principles?

Outcome Indicator questions:

1. What are the typical short term outcomes achieved through the activities of the DD Network programs (e.g., State Council, P&A, and UCEDD)?

2. What are the typical short term outcomes achieved through the collaborative activities of the State DD Networks?

Effectiveness questions:

1. What is the relationship between the outcomes achieved by the DD Network programs (e.g., State Council, P&A, and UCEDD) and the processes they used to affect those outcomes?

2. What is the relationship between the outcomes achieved by the State DD Networks and the processes used to affect those outcomes?

3. To what extent have the DD Network programs (e.g., State Council, P&A, and UCEDD) been effective in achieving the purposes and principles of the DD Act?

4. To what extent have the State DD Networks been effective in achieving the purposes and principles of the DD Act?

5. What efficiencies are being used by DD Network programs (e.g., State Council, P&A, and UCEDD) to obtain high quality outputs and achievements?

6. What efficiencies are being used by the State DD Network obtain high quality outputs and achievements?

2. ADD Assessment

The design of the ADD assessment is essentially a collection of retrospective and current data that relate to ADD’s structures, processes, outputs, and outcomes to draw conclusions about influences on the efficiency and effectiveness of DD Network programs. We define “effectiveness” as the ability to meet objectives. Thus, the ADD assessment will examine ADD’s ability to meet its objectives, from the perspective of a variety of stakeholders (including Executive Directors of DD Network programs), the DD Network programs’ ability to meet their objectives, and the relationship between the two.

Westat will use a semi-structured interview guide to obtain information from ADD staff, Federal agency partners, national disability organization staff, and staff from Projects of National Significance (discretionary grants funded by ADD. Up to nine individuals per category will be identified with assistance from ADD. Interviews will be conducted by telephone.

The contractor, Westat, will obtain budget and cost allocation data from ADD at three points in time (e.g., 2005, 2007, and 2009) to assess changes in some of the key structures (inputs) for ADD. Data collected through interview and by web-based questionnaire will relate to a recent period (e.g., 2009 and 2010).

Program materials will be obtained from ADD or the ADD website and reviewed by Westat staff.

To administer the web-based questionnaire, the Commissioner of ADD will send a letter to Executive Directors informing them that they will be contacted by Westat to participate in a web-based survey. Westat will then send an initial email to all Executive Directors to explain the purpose of the ADD assessment and provide a username and password to gain access to the questionnaire (Appendix A). Westat will also attach a separate file that contains instructions.

Data from each stakeholder group will be analyzed separately and then integrated to answer specific research questions (Table 4). Analysis of this qualitative data will primarily be descriptive. We will also conduct a descriptive analysis of the data extracted from background materials. Some data will be transformed into tabular format (e.g., to demonstrate budget appropriations or cost allocations over time).

3. Methods to Maximize Response Rates and Deal with Nonresponse

Identification of individuals to interview have, for the most part been in collaboration with Executive Directors or ADD. There has been excellent response, but when the contractor has been unable to interview a person who was selected, Executive Directors and ADD were asked for another name.

In the case of the web-based survey, Executive Directors have been asking ADD to include an assessment of ADD as part of the National Study of the ADD Programs for some time. Thus, ADD expects very good response to this survey. Nevertheless, within two weeks of distributing the questionnaire, Westat will follow up non-respondents by email to remind them to complete the survey. After two more weeks, another email will be sent, and after one more week, Westat will follow up with a telephone call.

We will keep track of those who do not respond to determine whether there are types of programs that have low response (e.g., region, allotment size, medical schools vs. non-medical schools for the UCEDDs). If we find significant differences in the types of programs that respond, we will control for this in our analysis by analyzing data separately according to the types of programs with low and high response. There are no plans to impute data.

4. Test of Procedures or Methods to be Undertaken

Westat staff worked with three DD Network program Executive Directors to develop the web-based questionnaire. Thus, no cognitive testing was undertaken.
