Development and validation of the cognitive-behavioral therapy skills questionnaire

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Understanding mechanisms of change in cognitive-behavioral therapy (CBT) is crucial for treatment optimization.
• Limited research has quantitatively assessed CBT skill acquisition, especially in complex patient profiles.
• A validated tool is needed to measure CBT skill use for clinical utility.

Purpose of the Study:

• To develop and validate the Cognitive-Behavioral Therapy Skills Questionnaire (CBTSQ).
• To assess the clinical utility of the CBTSQ in measuring CBT skill acquisition.
• To examine the relationship between CBT skill use and treatment outcomes.

Main Methods:

• Study 1: Item development and factor analysis (exploratory and confirmatory) of the CBTSQ using two large samples (n=350, n=378).
• Study 2: Investigated criterion validity of the CBTSQ in a patient sample undergoing CBT-oriented treatment.
• Statistical analyses included factor analysis, internal consistency checks, and regression analyses.

Main Results:

• The CBTSQ demonstrated a robust two-factor structure: Behavioral Activation and Cognitive Restructuring.
• Both factors showed good internal consistency and expected relationships with other psychological constructs.
• CBTSQ scores increased post-treatment, with skill scores predicting reduced psychiatric symptoms and depression.

Conclusions:

• The CBTSQ is a promising measure for assessing CBT skill acquisition.
• The questionnaire can aid therapists and patients in monitoring progress during CBT.
• Validated measurement of CBT skills supports understanding treatment mechanisms and outcomes.
