Abstract

Short Dark Triad Personality Test (SD3-41) normative dataset currently contains 561 participant records collected between Jun 11, 2026 and Jul 16, 2026 .

This psychometric dataset currently includes 561 anonymous participant responses collected through voluntary participation. The observed mean score was 49.11 with a standard deviation of 14.25, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated good reliability (Cronbach alpha = 0.87). Observed skewness (0.38) and kurtosis (0.04) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.

Normative Data Notice

A total of 561 participant responses were available for this assessment. Dimension-level norms were calculated using 561 valid response records. Approximately 0 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.
