Abstract

Paranoid Personality Scale (PPS) normative dataset currently contains 473 participant records collected between Jun 11, 2026 and Oct 31, 2026 .

This psychometric dataset currently includes 473 anonymous participant responses collected through voluntary participation. The observed mean score was 59.98 with a standard deviation of 17.94, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.921). Observed skewness (-0.61) and kurtosis (-0.14) 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
  • Q21 (r = 0.21)
    I prefer meeting new people instead of maintaining close relationships.
  • Q24 (r = -0.01)
    I'm defensive in my interactions.
The lowest item–total correlation was observed for Q24 ("I'm defensive in my interactions."; r = -0.01), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 473 participant responses were available for this assessment. Dimension-level norms were calculated using 473 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.
