Thalassophobia Severity Screening Scale (TSSS)
normative dataset currently contains
534
participant records collected between
Jun 11, 2026
and
Jul 19, 2026
.
This psychometric dataset currently includes 534 anonymous participant responses collected through voluntary participation. The observed mean score was 51.78 with a standard deviation of 13.33, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated acceptable reliability (Cronbach alpha = 0.72). Observed skewness (-0.13) and kurtosis (0.94) 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 = 0.23)
If the water looks dark, I prefer to stay near the edge.
Q2
(r = 0.24)
I prefer shallow water where I can see the bottom.
Q3
(r = 0.23)
I do not like being too far from land when on a boat.
Q4
(r = 0.27)
If the water is deep, I prefer not to go in.
Q5
(r = 0.18)
I prefer watching the sea from far away.
Q6
(r = 0.26)
I feel relaxed when I can see fish swimming in deep water.
Q10
(r = 0.15)
If the waves are strong, I like to stay on the sand and watch.
Q12
(r = 0.27)
If I cannot see what is under the water, I stay out.
Q13
(r = 0.12)
Sometimes I wonder what is under the sea surface.
Q14
(r = 0.09)
I sometimes imagine what the ocean looks like far below.
Q19
(r = 0.2)
I sometimes skip activities that involve deep water.
Q20
(r = 0.05)
I enjoy swimming or wading in pools more than the sea.
The lowest item–total correlation was observed for Q20 ("I enjoy swimming or wading in pools more than the sea."; r = 0.05), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice
A total of
534
participant responses were available for this assessment.
Dimension-level norms were calculated using
534
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.
