Abstract

Kinsey-Style Sexual Orientation Scale (KSOS-20) normative dataset currently contains 2490 participant records collected between Jun 10, 2026 and Jul 25, 2026 .

This psychometric dataset currently includes 2490 anonymous participant responses collected through voluntary participation. The observed mean score was 62.01 with a standard deviation of 13.82, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated acceptable reliability (Cronbach alpha = 0.782). Observed skewness (-0.79) and kurtosis (1.57) 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 identified9 itemsthat may benefit from future review.

Items Recommended for Future Review
  • Q5 (r = 0.28)
    I have felt romantic attraction toward someone of the opposite sex.
  • Q6 (r = 0.23)
    I have felt physical attraction toward someone of the opposite sex.
  • Q7 (r = 0.22)
    I have imagined being in a long-term relationship with someone of the opposite sex.
  • Q8 (r = 0.15)
    I often notice people of the opposite sex in an attractive way.
  • Q16 (r = 0.21)
    I feel comfortable discussing sexuality openly.
  • Q17 (r = -0.06)
    I rarely experience strong sexual attraction toward anyone.
  • Q18 (r = 0.08)
    Sexual attraction plays a small role in my relationships.
  • Q19 (r = 0.12)
    I can enjoy emotional intimacy without sexual attraction.
  • Q20 (r = -0.06)
    I often experience little or no sexual desire.
The lowest item–total correlation was observed for Q17 ("I rarely experience strong sexual attraction toward anyone."; r = -0.06), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice

A total of 2490 participant responses were available for this assessment. Dimension-level norms were calculated using 2490 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.
