# of studies reporting psychometric properties: 2
- No normative data have been established for the SCI population
- Published data for the SCI population is available for comparison (see the Interpretability section of the Study Details sheet).
- Higher scores indicate greater levels of distress.
- Normative data for the general population are available from the DASS manual which must be ordered, however these are based on the full DASS (42 items).
- For the DASS-21, the following cut-off scores have been recommended for each subscale (subscale scores = sum of item scores):
MCID: not established in SCI
SEM: not established in SCI
MDC: not established in SCI
No values were reported for the reliability of the DASS-21 for the SCI population.
- Correlation of the DASS-21 Anxiety subscale is High with the Brief Symptom Inventory Anxiety subscale (r = 0.61).
- Correlation of the DASS-21 Depression subscale is High with the Brief Symptom Inventory Depression subscale (r = 0.70).
- The Depression subscale of the DASS-21 is reported to have a sensitivity of 57.0% and a specificity of 67.0%.
- The Anxiety subscale of the DASS-21 is reported to have a sensitivity of 86.0% and a specificity of 64.0%.
(Mitchell et al. 2008)
No values were reported for the responsiveness of the DASS-21 for the SCI population.
No values were reported for the presence of floor/ceiling effects in the DASS-21 for the SCI population.
