Normative and Psychometric Statistics
PRELIMINARY N=10 α=0 4Countries
Abstract

Pathological Lying Assessment (PLA) normative dataset currently contains 10 participant records collected between Jun 25, 2026 and Jul 12, 2026 .

This psychometric dataset currently includes 10 anonymous participant responses collected through voluntary participation. The observed mean score was 39.5 with a standard deviation of 16.4, indicating moderate score variability within the sampled population. Internal consistency reliability analysis produced a Cronbach alpha of 0, which falls below commonly accepted psychometric standards and should be interpreted cautiously until additional data are collected. Observed skewness (0.32) and kurtosis (-1.69) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.

Note. Internal consistency was estimated using Cronbach alpha. Reliability estimates are based on the current normative dataset and may change as additional responses are collected.
Item–Total Correlations
Insufficient Sample Size

Item–total correlations are not currently reported because the assessment has fewer than 100 participant responses. Psychometric item analysis requires a larger sample to produce stable and interpretable estimates.

Normative Data Notice

A total of 10 participant responses were available for this assessment. Dimension-level norms were calculated using 10 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.
