Measuring cognitive vulnerability to depression in adolescence: reliability, validity, and gender differences.

Area of Science:

• Psychology
• Clinical Psychology
• Developmental Psychology

Background:

• Existing measures of cognitive vulnerability to depression in adolescents exhibit limitations.
• Previous instruments often demonstrate poor internal consistency reliability.
• Hypothesized components of cognitive vulnerability have not been fully assessed by prior measures.

Purpose of the Study:

• To evaluate the psychometric properties of the newly developed Adolescent Cognitive Style Questionnaire (ACSQ).
• To establish the reliability and validity of the ACSQ for assessing cognitive vulnerability to depression in adolescents.

Main Methods:

• High school students completed the ACSQ, alongside measures of negative life events, depressive symptoms, and internalizing/externalizing symptoms.
• Psychometric properties including internal consistency, test-retest reliability, and construct validity were assessed.
• Confirmatory factor analysis was used to determine the factor structure of the ACSQ.

Main Results:

• The ACSQ demonstrated excellent internal consistency reliability and good test-retest reliability.
• Confirmatory factor analysis revealed three latent factors within the ACSQ.
• Significant correlations with other measures supported the construct validity of the ACSQ; it predicted depressive and internalizing symptoms, and mediated gender differences in depression.

Conclusions:

• The Adolescent Cognitive Style Questionnaire (ACSQ) is a reliable and valid instrument for measuring cognitive vulnerability to depression in adolescents.
• The ACSQ effectively predicts depressive symptoms and sheds light on the gender disparity in adolescent depression.
• This measure addresses limitations of previous instruments, offering a robust tool for research and clinical practice.
