简要总结
This observational study evaluates the psychometric properties of the Behavioral Activation for Depression Scale (BADS) in individuals with substance use disorders. The study examines the scale's internal structure, reliability, and validity using data from 289 participants who completed the BADS. External and incremental validity analyses were conducted in a subsample of 127 participants for whom additional clinical measures were available, including assessments of symptom severity, anxiety, impulsivity, and anger expression. This approach reflects the availability of complete data for each analytic component and allows for a comprehensive evaluation of the BADS in a clinical population.
详细描述
This study employs a cross-sectional observational design to evaluate the psychometric performance of the Behavioral Activation for Depression Scale (BADS) in individuals with substance use disorders. The validation process consisted of two complementary analytic components based on data availability.
First, analyses of internal structure, reliability, and item-level performance were conducted using data from 289 participants who completed the BADS. These analyses included advanced psychometric methods to evaluate the dimensional structure and measurement properties of the scale.
Second, external and incremental validity analyses were conducted in a subsample of 127 participants for whom complete data were available on additional validated self-report measures assessing clinically relevant constructs, including symptom severity, anxiety, impulsivity, and anger expression. This subsample approach reflects the naturalistic data collection process in clinical settings and allowed for the examination of the BADS' relationships with external criteria without imputing missing data.
Together, these analyses provide a comprehensive evaluation of the BADS, integrating evidence from internal psychometric validation and external criterion-related validity in a clinical population with substance use disorders.

研究组 & 干预措施
Individuals With Substance Use Disorders
Single clinical group composed of adults receiving treatment for substance use disorders who completed the Behavioral Activation for Depression Scale (BADS) and additional self-report measures as part of a cross-sectional observational study.
结局指标
主要结局
Psychometric Validity of the Behavioral Activation for Depression Scale (BADS)
时间窗: Baseline, pre-intervention (single cross-sectional assessment at study enrollment)
Psychometric properties of the Behavioral Activation for Depression Scale (BADS), including internal structure (confirmatory factor analysis), internal consistency reliability (Cronbach's alpha / omega), and construct validity (convergent and discriminant validity), assessed using self-report data collected at a single time point in individuals with substance use disorders. Subscale scores will also be examined, with higher scores reflecting greater expression of the respective behavioral domains.
次要结局
- Convergent and Discriminant Validity of the Behavioral Activation for Depression Scale With the Borderline Symptom List-23(Baseline, pre-intervention (single cross-sectional assessment conducted at study enrollment))
- Convergent Validity of the Behavioral Activation for Depression Scale With the Environmental Reward Observation Scale(Baseline, pre-intervention (single cross-sectional assessment at study enrollment))
