STRONG N=408 α=0.897 45Countries

Deenz Schizotypal Personality Scale (DSPS-27) normative dataset currently contains 408 participant records collected between Jun 11, 2026 and Aug 19, 2026 .

This psychometric dataset currently includes 408 anonymous participant responses collected through voluntary participation. The observed mean score was 61.26 with a standard deviation of 14.59, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated good reliability (Cronbach alpha = 0.897). Observed skewness (-0.88) and kurtosis (1.19) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.

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 identified2 itemsthat may benefit from future review.

Items Recommended for Future Review
  • Q22 (r = 0.25)
    I rarely smile or laugh.
  • Q27 (r = 0.26)
    I talk to myself a lot.
The lowest item–total correlation was observed for Q22 ("I rarely smile or laugh."; r = 0.25), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 408 participant responses were available for this assessment. Dimension-level norms were calculated using 408 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.
