[New questionnaire to evaluate psychological treatment effects]

Area of Science:

• Psychology
• Psychometrics

Background:

• Psychological treatments require validated tools for outcome evaluation.
• The Cognitive Behavioral Assessment for outcome evaluation (CBA-VE) questionnaire was developed for this purpose.

Purpose of the Study:

• To evaluate the validity and reliability of the five constructs of the CBA-VE questionnaire.
• To assess the psychometric properties in both normal and clinical populations.

Main Methods:

• The study analyzed two samples: a "Normal" group (250 adults, 51 students) and a "Clinical" group (261 adults in therapy).
• The CBA-VE questionnaire, with 80 items on a 5-point Likert scale, measures anxiety, depression, psychological distress, wellbeing, and perceived change.

Main Results:

• The CBA-VE demonstrated excellent psychometric characteristics, including good reliability, internal consistency, and structural validity.
• Factorial loadings were consistent, significant, and similar across both groups.
• Clinical subjects reported higher distress and lower wellbeing/change perception, aligning with expectations.

Conclusions:

• The CBA-VE questionnaire is a psychometrically sound instrument for evaluating psychological interventions.
• It reliably assesses key psychological constructs in diverse populations.
• The findings support its use in counseling and psychotherapy outcome research.
