Chemical Dependency Counselor CCDC Exam Research & Evidence-Based Practice 4 — Questions and Answers
Question 1: Which of the following best describes 'treatment fidelity' in EBP implementation?
- Client satisfaction with treatment
- Adherence to the core components of a manualized treatment (Correct answer)
- The counselor's personal loyalty to a therapeutic approach
- Confidentiality of treatment records
Correct answer: Adherence to the core components of a manualized treatment
Treatment fidelity refers to the degree to which an intervention is delivered as intended, which is essential for replicating research outcomes.
Question 2: A meta-analysis that reports an effect size of d=0.80 for CBT in substance use treatment indicates:
- A weak, clinically insignificant effect
- A large effect size suggesting strong treatment impact (Correct answer)
- That 80% of participants improved
- A statistically non-significant result
Correct answer: A large effect size suggesting strong treatment impact
Cohen's d of 0.80 is conventionally classified as a large effect size, suggesting CBT has a substantial impact relative to comparison conditions.
Question 3: The purpose of a 'needs assessment' before implementing a new program is to:
- Satisfy accreditation requirements only
- Identify the specific problems, gaps, and resources in a target population (Correct answer)
- Market the program to potential clients
- Evaluate treatment outcomes post-implementation
Correct answer: Identify the specific problems, gaps, and resources in a target population
A needs assessment systematically gathers data about a population's problems and existing resources to inform program design.
Question 4: In the context of substance use research, 'external validity' addresses whether:
- The intervention caused the observed outcomes
- The study findings generalize to other settings and populations (Correct answer)
- The measurement tools are reliable
- Ethical standards were followed
Correct answer: The study findings generalize to other settings and populations
External validity concerns the generalizability of research findings beyond the specific sample and setting where the study was conducted.
Question 5: Which SAMHSA resource categorizes behavioral health interventions by evidence level for substance use disorders?
- The Diagnostic and Statistical Manual (DSM-5)
- The National Registry of Evidence-based Programs and Practices (NREPP) (Correct answer)
- The Merck Manual
- The Physician's Desk Reference
Correct answer: The National Registry of Evidence-based Programs and Practices (NREPP)
SAMHSA's NREPP (now the Evidence-Based Practices Resource Center) rates and lists behavioral health interventions by their evidence base.
Question 6: A counselor wants to know if there is a relationship between session attendance and treatment completion rates. Which analysis is most appropriate?
- T-test
- Correlation analysis (Correct answer)
- Factor analysis
- Analysis of variance (ANOVA)
Correct answer: Correlation analysis
Correlation analysis quantifies the strength and direction of the relationship between two continuous variables such as attendance and completion.
Question 7: The 'intention-to-treat' analysis principle in RCTs means:
- Only participants who completed treatment are analyzed
- All randomized participants are analyzed in their assigned groups regardless of compliance (Correct answer)
- Participants who drop out are excluded to reduce bias
- Only participants who intended to seek treatment are included
Correct answer: All randomized participants are analyzed in their assigned groups regardless of compliance
Intention-to-treat analysis preserves randomization and avoids bias by analyzing all participants as originally assigned, including dropouts.
