Deenz Suicidal Tendency Scale (DSTS-25)

Normative and Psychometric Statistics

Abstract

Deenz Suicidal Tendency Scale (DSTS-25) normative dataset currently contains 797 participant records collected between Jun 10, 2026 and Jun 29, 2026 .

This psychometric dataset currently includes 797 anonymous participant responses collected through voluntary participation. The observed mean score was 72.37 with a standard deviation of 17.91, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.945). Observed skewness (-1.34) and kurtosis (2.53) were examined as indicators of distribution quality. The distribution demonstrated mild departures from normality, although the overall score pattern remained broadly interpretable for preliminary normative purposes.

Item Analysis Interpretation

Item–total correlations were generally strong across the assessment, indicating that most items contribute effectively to the measurement of the underlying construct. The analysis identified1 itemthat may benefit from future review.

Items Recommended for Future Review
  • Q25 (r = 0.01)
    I have thought about ways to end my life.
The lowest item–total correlation was observed for Q25 ("I have thought about ways to end my life."; r = 0.01), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 797 participant responses were available for this assessment. Dimension-level norms were calculated using 592 valid response records. Approximately 205 response record(s) were excluded from dimension-level normative calculations due to incomplete response patterns.

Limitations

Normative statistics are derived from voluntary participation and may not represent all populations. Reliability estimates, percentile norms, and dimension statistics should be interpreted in the context of the current sample and may change as additional responses are collected.

Ethical Statement

All records included in this dataset were collected anonymously. No personally identifying information is stored. Data are intended for educational, psychometric, and research purposes.
