Development of a potential screening measure for adolescent depression

Area of Science:

• Psychiatry
• Psychometrics
• Adolescent Health

Background:

• Limited availability of adolescent-specific depression screening tools.
• Existing instruments may have limitations for adolescent populations.
• Need for multi-method development in mental health assessment.

Purpose of the Study:

• To develop and validate the Taouk Scale for Adolescent Depression.
• To create a reliable and valid screening instrument for adolescent depression.
• To incorporate novel indicators relevant to adolescent mental health.

Main Methods:

• Qualitative (focus groups) and quantitative (nation-wide survey) approaches.
• Development of a provisional 97-item scale based on expert and adolescent input.
• Exploratory and confirmatory factor analysis on a large secondary student sample (n=3087).

Main Results:

• A 28-item scale with four reliable factors: negative outlook, emotional distress, behavioral changes, and cognitive/somatic disturbances.
• Confirmatory factor analysis corroborated the scale's structure.
• Inclusion of novel items such as changes in clothing, property damage, risk-taking, school disengagement, substance abuse, and sexual activity.

Conclusions:

• The Taouk Scale for Adolescent Depression demonstrates sound psychometric properties.
• The scale is a potentially valid and reliable screening instrument for adolescent depression.
• Further research is needed to confirm criterion validity in clinically depressed samples.
