Paranoid Personality Scale (PPS)
normative dataset currently contains
318
participant records collected between
Jun 11, 2026
and
Aug 30, 2026
.
This psychometric dataset currently includes 318 anonymous participant responses collected through voluntary participation. The observed mean score was 60.89 with a standard deviation of 17.41, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.916). Observed skewness (-0.59) and kurtosis (-0.18) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.

Item–Total Correlations
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 = 0.28)
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
318
participant responses were available for this assessment.
Dimension-level norms were calculated using
318
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.
