Abstract

Developmental Trauma Profile (DTP) normative dataset currently contains 141 participant records collected between Jun 27, 2026 and Oct 29, 2026 .

This psychometric dataset currently includes 141 anonymous participant responses collected through voluntary participation. The observed mean score was 40.02 with a standard deviation of 17.86, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.979). Observed skewness (-0.97) and kurtosis (0.2) 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 identified3 itemsthat may benefit from future review.

Items Recommended for Future Review
  • Q84 (r = 0.23)
    I found it easy to say no.
  • Q134 (r = 0.21)
    I rarely reflect on my life.
  • Q144 (r = 0.02)
    I give up easily.
The lowest item–total correlation was observed for Q144 ("I give up easily."; r = 0.02), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 141 participant responses were available for this assessment. Dimension-level norms were calculated using 141 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.
