appears to be a combined reference to the Depression, Anxiety, and Stress Scale (DASS) —specifically the DASS-21 or DASS-42 —and a widely cited study involving 243 participants that examined mental health recovery. UNSW Sydney

While there is no single instrument named "DASS-243," this combination is frequently discussed in research contexts regarding psychological distress assessment. 1. Understanding the DASS Instrument

: The original full-length version consisting of 42 items (14 per scale).

: The short-form version consisting of 21 items (7 per scale). It is the most commonly used version in clinical and research settings due to its efficiency, typically taking only to complete. 2. Scoring and Interpretation

To interpret the DASS-21, you must first calculate the sum for each subscale and then multiply by 2 DASS-243

to make the results comparable to the original DASS-42 norms. University of Bristol Severity Level Depression (D) Anxiety (A) Stress (S) Extremely Severe

Depression Anxiety Stress Scales – Short Form (DASS-21) - NovoPsych

Strengths

  • Brief (DASS-21), easy to administer.
  • Separates depression, anxiety, and stress constructs.
  • Extensive validation across populations and cultures.

Purpose and Structure

The DASS-21 is a self-report questionnaire consisting of 21 items, divided into three subscales:

  1. Depression (7 items): Assesses the state of depression, including dysphoria, hopelessness, and devaluation of life.
  2. Anxiety (7 items): Measures the experience of anxiety, including subjective experience of anxious affect and physical symptoms.
  3. Stress (7 items): Evaluates the level of stress, including difficulty relaxing, nervous arousal, and being easily upset.

Limitations

  • Self-report biases (social desirability, insight).
  • Overlap between anxiety and stress items can complicate interpretation.
  • Not a diagnostic tool — high scores require clinical evaluation.
  • Severity cutoffs can vary slightly across studies and populations; use local norms when available.

Scoring

  • DASS-42:
    • Sum items for each subscale (range 0–42).
  • DASS-21:
    • Sum items for each subscale (range 0–21) then multiply each subscale score by 2 to be comparable to DASS-42 (range 0–42).
  • Severity ranges (DASS-42 metric; approximate):
    • Depression: Normal 0–9, Mild 10–13, Moderate 14–20, Severe 21–27, Extremely severe 28+
    • Anxiety: Normal 0–7, Mild 8–9, Moderate 10–14, Severe 15–19, Extremely severe 20+
    • Stress: Normal 0–14, Mild 15–18, Moderate 19–25, Severe 26–33, Extremely severe 34+
  • Interpretation: Higher scores = greater symptom severity; examine subscales separately (not summed together for a total clinical diagnosis).

Interpretation

While there are no strict cutoffs for determining clinical significance, the following guidelines are commonly used:

  • Depression:

    • 0-9: Normal
    • 10-13: Mild
    • 14-19: Moderate
    • 20-27: Severe
    • 28+: Extremely severe

  • Anxiety:

    • 0-7: Normal
    • 8-9: Mild
    • 10-14: Moderate
    • 15-19: Severe
    • 20+: Extremely severe

  • Stress:

    • 0-7: Normal
    • 8-11: Mild
    • 12-17: Moderate
    • 18-25: Severe
    • 26+: Extremely severe
