Abstract

Deenz Neurodiversity Scale (DNS) normative dataset currently contains 4015 participant records collected between Jun 9, 2026 and Oct 13, 2026 .

This psychometric dataset currently includes 4015 anonymous participant responses collected through voluntary participation. The observed mean score was 54.87 with a standard deviation of 12.37, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated good reliability (Cronbach alpha = 0.844). Observed skewness (-0.2) and kurtosis (0.29) 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 identified11 itemsthat may benefit from future review.

Items Recommended for Future Review
  • Q2 (r = 0.28)
    Making new friends can be challenging for me.
  • Q4 (r = 0.27)
    I prefer familiar environments over new ones.
  • Q8 (r = 0.3)
    I pay close attention to details and often see things that others might not.
  • Q15 (r = 0.25)
    I love thinking deeply and talking about big ideas and philosophy.
  • Q21 (r = 0.26)
    I find it easier to understand information when it's spoken.
  • Q22 (r = 0.25)
    I take my time to think and decide, and I need a lot of it.
  • Q23 (r = 0.27)
    I really love certain hobbies and get super into them.
  • Q24 (r = 0.06)
    I'm good at solving problems and thinking creatively.
  • Q26 (r = 0.28)
    My handwriting might not be very neat or consistent.
  • Q31 (r = 0.29)
    I switch between being very social and wanting to be alone.
  • Q32 (r = -0.03)
    I notice that I often overestimate or underestimate what I can do.
The lowest item–total correlation was observed for Q32 ("I notice that I often overestimate or underestimate what I can do."; r = -0.03), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 4015 participant responses were available for this assessment. Dimension-level norms were calculated using 4015 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.
