Young Mania Rating Scale (YMRS)
Young Mania Rating Scale (YMRS) normative dataset currently contains 4 participant records collected between Jul 4, 2026 and Jul 22, 2026 .
This psychometric dataset currently includes 4 anonymous participant responses collected through voluntary participation. The observed mean score was 55.75 with a standard deviation of 18.43, 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 (0.11) and kurtosis (-5.24) 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–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.

A total of 4 participant responses were available for this assessment. Dimension-level norms were calculated using 4 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
