Psychoanalysis Research Methods and Evidence 2 — Questions and Answers
Question 1: Which research design is most commonly criticized for lacking a control group in psychoanalytic outcome studies?
- Randomized controlled trial
- Single-case study design (Correct answer)
- Meta-analysis
- Longitudinal cohort study
Correct answer: Single-case study design
Single-case studies, common in psychoanalytic research, are criticized for the absence of a control group, making causal inference difficult.
Question 2: What does the term 'allegiance effect' refer to in psychotherapy research?
- Therapist loyalty to a theoretical school influencing outcomes
- Patient attachment to a therapist affecting dropout rates
- Researcher bias favoring the therapy they believe in (Correct answer)
- The effect of therapeutic alliance on symptom reduction
Correct answer: Researcher bias favoring the therapy they believe in
The allegiance effect describes how researchers who favor a particular therapy tend to produce studies showing that therapy in a more positive light.
Question 3: The Psychotherapy Process Q-Set (PQS) is used in psychoanalytic research primarily to:
- Measure patient symptom severity pre- and post-treatment
- Quantify and compare therapeutic process across sessions (Correct answer)
- Assess therapist adherence to a treatment manual
- Track changes in patient dream content over time
Correct answer: Quantify and compare therapeutic process across sessions
The PQS is a 100-item card-sort instrument designed to provide a standardized description of the therapeutic process, enabling comparison across different therapies.
Question 4: Which statistical concept is central to combining results from multiple psychoanalytic outcome studies?
- Analysis of variance (ANOVA)
- Effect size (Cohen's d) (Correct answer)
- Pearson correlation coefficient
- Chi-square statistic
Correct answer: Effect size (Cohen's d)
Effect size, commonly expressed as Cohen's d, is the key statistic in meta-analyses as it allows comparison of results across studies with different scales.
Question 5: In the context of psychoanalytic research, what is 'naturalistic effectiveness research'?
- Studies conducted outdoors to reduce lab anxiety
- Research examining therapy outcomes in real-world clinical settings (Correct answer)
- Studies using nature metaphors to analyze patient language
- Research on the natural course of untreated psychological disorders
Correct answer: Research examining therapy outcomes in real-world clinical settings
Naturalistic effectiveness research studies therapy as it is actually practiced in routine clinical settings, contrasting with the controlled conditions of efficacy trials.
Question 6: The 'dose-effect relationship' in psychotherapy research, as studied by Howard et al., refers to:
- The increasing side effects of medication combined with therapy
- The relationship between number of sessions and patient improvement (Correct answer)
- How therapist dosage of interpretations affects insight
- The effect of session length on therapeutic alliance
Correct answer: The relationship between number of sessions and patient improvement
Howard et al.'s dose-effect research demonstrated a predictable relationship between the number of therapy sessions received and the percentage of patients who improve.
Question 7: Which approach to validity is most threatened when psychoanalytic concepts like 'the unconscious' cannot be directly observed?
- Face validity
- Predictive validity
- Construct validity (Correct answer)
- Concurrent validity
Correct answer: Construct validity
Construct validity is threatened when a theoretical concept (e.g., the unconscious) cannot be adequately operationalized or directly observed, making it unclear whether measures truly capture the construct.
