This study document brings together 9 carefully worded exam questions drawn from SW650 -
SOCIAL WORK RESEARCH METHODS Study Guide UP-TO-DATE EXAM QUESTIONS AND
100% ACCURATE SOLUTIONS VERIFIED ANSWERS - INSTANT PDF DOWNLOAD., with the
strongest emphasis placed on Critically appraise and select appropriate research designs for social
work practice questions, Evaluate measurement properties and sampling strategies for validity and
generalizability and Apply ethical principles and quantitative/qualitative analytic techniques to
research scenarios. Every item follows the wording style and level of reasoning you meet in the
real paper, and each one is paired with a clear rationale so the correct choice is never a guess.
Work through the set at your own pace, mark the questions that slow you down, then come back to
them until the reasoning feels automatic. Learners who revise this way walk into the exam room
recognising the pattern behind the questions instead of meeting them for the first time. Keep going
- steady, honest practice is what turns a difficult paper into a comfortable pass.

, Q1 CRITICALLY APPRAISE AND SELECT APPROPRIATE RESEARCH DESIGNS FOR SOCIAL
WORK PRACTICE QUESTIONS
A social work researcher wants to test whether a new housing intervention
reduces homelessness recidivism while accounting for unmeasured time-invariant
confounders. Which design best balances internal validity and ethical feasibility?
A. Randomized controlled trial with waitlist control
B. Regression discontinuity design using a cutoff score
C. Interrupted time series with nonequivalent comparison group
D. Difference-in-differences with propensity score matching CORRECT
RATIONALE: Difference-in-differences with propensity score matching controls for both observed
and unobserved time-invariant confounders, offering strong internal validity when randomization
is infeasible. RCTs are ethical but often impractical for housing interventions; regression
discontinuity requires a sharp cutoff; interrupted time series lacks a clear counterfactual.
Q2 EVALUATE MEASUREMENT PROPERTIES AND SAMPLING STRATEGIES FOR VALIDITY
AND GENERALIZABILITY
A scale measuring depression yields a Cronbach's alpha of 0.92, but item-total
correlations for two items are below 0.30. What is the most appropriate
psychometric interpretation?
A. The scale has excellent internal consistency and should be retained as is.
B. The high alpha indicates redundancy; the two items should be removed to improve validity.
C. The low item-total correlations suggest those items may measure a different construct,
warranting further factor analysis. CORRECT
D. Alpha is inflated by the large number of items; the scale should be shortened regardless of
item performance.
RATIONALE: High alpha does not guarantee unidimensionality; low item-total correlations signal
potential multidimensionality or poor item quality, requiring factor analysis. Removing items solely
to raise alpha can harm content validity; alpha inflation by item count is a concern but not the
primary issue here.
