Normative and Psychometric Statistics
STRONG N=239 α=0.895 36Countries

Deenz Schizotypal Personality Scale (DSPS-27) normative dataset currently contains 239 participant records collected between Jun 11, 2026 and Jul 13, 2026 .

This psychometric dataset currently includes 239 anonymous participant responses collected through voluntary participation. The observed mean score was 62.56 with a standard deviation of 14.24, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated good reliability (Cronbach alpha = 0.895). Observed skewness (-1.06) and kurtosis (1.96) 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 identified2 itemsthat may benefit from future review.

Items Recommended for Future Review
  • Q10 (r = 0.25)
    I believe in curses.
  • Q22 (r = 0.27)
    I rarely smile or laugh.
The lowest item–total correlation was observed for Q10 ("I believe in curses."; r = 0.25), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 239 participant responses were available for this assessment. Dimension-level norms were calculated using 239 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.
