Abstract
Megalophobia Severity Screening Scale (MSSS-20)
normative dataset currently contains
767
participant records collected between
Jun 11, 2026
and
Oct 21, 2026
.
This psychometric dataset currently includes 767 anonymous participant responses collected through voluntary participation. The observed mean score was 55.14 with a standard deviation of 17.24, indicating moderate score variability within the sampled population. Internal consistency reliability analysis produced a Cronbach alpha of 0.679, which falls below commonly accepted psychometric standards and should be interpreted cautiously until additional data are collected. Observed skewness (-0.1) and kurtosis (-0.11) 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 identified12
itemsthat may benefit from future review.
Items Recommended for Future Review
Q1
(r = 0.27)
Very large buildings sometimes make me feel uncomfortable.
Q2
(r = 0.24)
I prefer staying away from enormous statues or monuments.
Q3
(r = 0.17)
Massive ships or cruise liners feel intimidating to me.
Q5
(r = 0.2)
Seeing extremely large objects can feel overwhelming.
Q7
(r = 0.08)
Large open environments usually feel comfortable to me.
Q8
(r = 0.26)
I enjoy visiting places with giant structures.
Q9
(r = 0.19)
Huge objects rarely make me nervous.
Q12
(r = 0.22)
If a structure looks overwhelmingly large, I avoid getting too close.
Q13
(r = 0.19)
I sometimes avoid places known for giant monuments or buildings.
Q16
(r = 0.24)
I enjoy visiting large museums, stadiums, or public structures.
Q17
(r = 0.23)

Q20
(r = 0.09)

767
participant responses were available for this assessment.
Dimension-level norms were calculated using
767
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.
