Abstract
Kinsey-Style Sexual Orientation Scale (KSOS-20)
normative dataset currently contains
4019
participant records collected between
Jun 10, 2026
and
Aug 29, 2026
.
This psychometric dataset currently includes 4019 anonymous participant responses collected through voluntary participation. The observed mean score was 61.77 with a standard deviation of 13.86, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated acceptable reliability (Cronbach alpha = 0.783). Observed skewness (-0.77) and kurtosis (1.36) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.

Item–Total Correlations
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 = 0.26)
I have felt romantic attraction toward someone of the opposite sex.
Q6
(r = 0.2)
I have felt physical attraction toward someone of the opposite sex.
Q7
(r = 0.19)
I have imagined being in a long-term relationship with someone of the opposite sex.
Q8
(r = 0.12)
I often notice people of the opposite sex in an attractive way.
Q16
(r = 0.23)
I feel comfortable discussing sexuality openly.
Q17
(r = -0.05)
I rarely experience strong sexual attraction toward anyone.
Q18
(r = 0.08)
Sexual attraction plays a small role in my relationships.
Q19
(r = 0.13)
I can enjoy emotional intimacy without sexual attraction.
Q20

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 = -0.05), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice
A total of
4019
participant responses were available for this assessment.
Dimension-level norms were calculated using
4019
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.
