Is DASS 21 Reliability and validity?

The DASS-21 was found to have commendable psychometric properties. It is reliable, valid and easy to administer. Its utility by clinicians will enhance the diagnoses of depression, anxiety and stress among university students.

Is DASS test reliable?

Cronbach internal consistency of the entire scale was 0.89. Item-total correlations ranged from 0.51 to 0.75. Test- retest and split-half reliability coefficient scores were 0.99 and 0.96 respectively. These results demonstrate that the DASS is a valid and reliable instrument.

Is a DASS 21 qualitative or quantitative?

The DASS is a quantitative measure of distress along the 3 axes of depression, anxiety1 and stress2. It is not a categorical measure of clinical diagnoses. Emotional syndromes like depression and anxiety are intrinsically dimensional – they vary along a continuum of severity (independent of the specific diagnosis).

What does the DASS 21 measure?

Depression, Anxiety and Stress Scale – 21 Items (DASS-21) The anxiety scale assesses autonomic arousal, skeletal muscle effects, situational anxiety, and subjective experience of anxious affect. The stress scale is sensitive to levels of chronic non- specific arousal.

How is DASS 21 calculated?

Sum scores are computed by adding up the scores on the items per (sub)scale and multiplying them by a factor 2. Sum scores for the total DASS-total scale thus range between 0 and 120, and those for each of the subscales may range between 0 and 42.

Is DASS 21 valid?

The DASS-21 is reliable and suitable for use to assess symptoms of common mental health problems, especially depression and anxiety among Vietnamese adolescents. However, its ability in detecting stress among these adolescents may be limited. Further research is warrant to explore these results.

When do you use DASS 21?

The DASS-21 is the short form of the DASS-42, a self-report scale designed to measure the negative emotional states of depression, anxiety and stress. This scale is suitable for clinical settings to assist in diagnosis and outcome monitoring, as well as non-clinical settings as a mental health screener.

How long does it take to complete the DASS 21?

The DASS-21 is a clinical assessment that measures the three related states of depression, anxiety and stress. It has 21 questions and takes about 3 minutes to complete.

Can Dass 21 be used for adolescents?

Conclusion: The DASS-21 can be reliably used to measure general distress in adolescents, but the subscales fail to discriminate between the 3 states. Our results indicate that this lack of discrimination does not reduce with increasing age.

Can DASS 21 be used on children?

The DASS has been used with adolescents down to 14 years of age, but we have little data from that age range to confirm the validity of the scales. We would not recommend using the DASS with children below 14 years because it is likely that some children would not fully understand all of the terms used.

Is the DASS 21 a valid measure?

The reliability and validity of both the DASS and the DASS-21 have been replicated among clinical [7,8], as well as non-clinical adult samples [6,9–11]. The same three-factor structure has been seen when the measure is used among diverse cultural and ethnic groups [12,13].

What is reliability and validity in qualitative research?

In Quantitative research, reliability refers to consistency of certain measurements, and validity – to whether these measurements “measure what they are supposed to measure”. Things are slightly different, however, in Qualitative research.

What are the different types of quality for qualitative research?

Same for quantitative research, quality for qualitative research can be assessed in terms of validity, reliability, and generalizability. Validity Validity in qualitative research means “appropriateness” of the tools, processes, and data.

Can the DASS-21 assess stress among Vietnamese adolescents?
