Introduction

The Depression, Anxiety and Stress Scale (DASS-21) is recognized as being a widely used measure for the assessment of negative emotional states. While the DASS-21 has been widely used for assessing mental health in Pakistan, limited research has been done regarding its factor structure and measurement invariance.

Objectives

To assess the factor structure and measurement invariance of the DASS-21 among young adults in Pakistan.

Methods

A large sample of 1361 Pakistani young adults had completed the scale during the current study comprising 666 males and 695 females with a mean age of 24.51 years.

Results

Excellent internal consistency reliability was found for the overall DASS-21 and its three subscales (depression, anxiety and stress) ranging from r = .86 to .71 (Cronbach alpha). Moreover, the three subscales were strongly and significantly associated with one another. Additionally, the results showed a good fit of the three-factor model and the one-factor model of the DASS-21 aimed at assessing gender psychological distress. Strong measurement invariance was found regarding gender therefore showing that the DASS-21 is understood and interpreted similarly by males and females. However, little evidence was found regarding the three subscales (depression, anxiety and stress) for the measurement of three distinct constructs.

Conclusions

These findings confirm the utility of the DASS-21 for measuring mental health in Pakistan among young adults.
