Megalophobia Severity Screening Scale (MSSS-20)
normative dataset currently contains
267
participant records collected between
Jun 11, 2026
and
Jun 27, 2026
.
This psychometric dataset currently includes 267 anonymous participant responses collected through voluntary participation. The observed mean score was 48.48 with a standard deviation of 13.13, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated acceptable reliability (Cronbach alpha = 0.743). Observed skewness (0.8) and kurtosis (1.56) 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 identified8
itemsthat may benefit from future review.
Items Recommended for Future Review
Q1
(r = 0.29)
Very large buildings sometimes make me feel uncomfortable.
Q2
(r = 0.2)
I prefer staying away from enormous statues or monuments.
Q3
(r = 0.07)
Massive ships or cruise liners feel intimidating to me.
Q4
(r = 0.23)
I feel uneasy when standing close to skyscrapers.
Q5
(r = 0.03)
Seeing extremely large objects can feel overwhelming.
Q7
(r = 0.02)
Large open environments usually feel comfortable to me.
Q17
(r = 0.26)

Normative Data Notice
A total of
267
participant responses were available for this assessment.
Dimension-level norms were calculated using
173
valid response records.
Approximately
94
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.
