Coulrophobia Severity Scale (CSS)

Normative and Psychometric Statistics
DEVELOPING N=26 α=0.926 17Countries
Abstract

Coulrophobia Severity Scale (CSS) normative dataset currently contains 26 participant records collected between Jul 17, 2026 and Oct 15, 2026 .

This psychometric dataset currently includes 26 anonymous participant responses collected through voluntary participation. The observed mean score was 55.27 with a standard deviation of 22.94, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.926). Observed skewness (-0.13) and kurtosis (-1.21) 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 26 participant responses were available for this assessment. Dimension-level norms were calculated using 26 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.
