Research and Program Evaluation Flashcards

A social work agency wants to know if its substance use intervention works across different racial groups. Which analytical approach best addresses this?

Answer: Moderation analysis (interaction testing)

Moderation analysis tests whether the relationship between treatment and outcome differs across subgroups such as racial categories.

Which research design is most appropriate for exploring the lived experience of aging adults in assisted living facilities?

The Belmont Report's principle of justice in research primarily requires:

Answer: Fair distribution of research burdens and benefits across populations

The justice principle mandates equitable selection of research participants so that vulnerable groups are neither exploited nor excluded from potential benefits.

A researcher uses Cohen's d = 0.80 to describe an intervention effect. According to Cohen's conventions, this is:

Answer: A large effect size

Cohen's conventions classify d = 0.20 as small, d = 0.50 as medium, and d = 0.80 as large.

In single-subject design (SSD), the baseline phase is labeled:

Answer: A phase

In SSD notation, 'A' refers to the baseline (no-treatment) phase and 'B' refers to the intervention phase.

Which statistical test is most appropriate for comparing the mean anxiety scores of three different treatment groups?

Answer: One-way ANOVA

One-way ANOVA compares means across three or more independent groups while controlling the familywise error rate.

An evaluator collects data from program staff, clients, and community members to assess a housing program. This strategy exemplifies:

Answer: Triangulation of data sources

Triangulation uses multiple sources or methods to corroborate findings and strengthen the credibility of conclusions.
