Summary
A shorter, 24-item Multidimensional Depression Assessment Scale (MDAS24-4pt) effectively measures depression in Asian adolescents. This efficient tool retains robust psychometric properties for easier administration and diagnosis.
Area of Science:
- Psychiatry
- Adolescent Mental Health
- Psychometrics
Background:
- Depression is a significant mental health concern among Asian adolescents.
- The 52-item Multidimensional Depression Assessment Scale (MDAS) is effective but lengthy.
- There is a need for a more concise measure for easier administration.
Purpose of the Study:
- To shorten the MDAS using Rasch analysis.
- To evaluate the psychometric properties of the shortened scale in Asian adolescents.
Main Methods:
- Rasch analysis was employed to reduce the scale from 52 to 24 items.
- A sample of 1996 Asian adolescents (aged 12-18) participated.
- The original 5-point scale was adapted to a 4-point Likert scale.
Main Results:
- The shortened 24-item scale (MDAS24-4pt) demonstrated high internal consistency (Cronbach's alpha > 0.89).
- Strong correlations were found between MDAS24-4pt and the original MDAS (> 0.90).
- Significant correlations were also observed with the Patient Health Questionnaire (PHQ-9) (> 0.70).
Conclusions:
- The MDAS24-4pt is a psychometrically sound and efficient instrument for assessing depression in Asian adolescents.
- The shortened scale offers a practical alternative to the original MDAS.
- This tool aids in the timely detection of depressive symptoms in this population.
