Deenz Psychotic Rating Scale (DPRS-45)
normative dataset currently contains
296
participant records collected between
Jun 11, 2026
and
Jul 27, 2026
.
This psychometric dataset currently includes 296 anonymous participant responses collected through voluntary participation. The observed mean score was 44.76 with a standard deviation of 21.56, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.975). Observed skewness (0.14) and kurtosis (-0.78) 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 identified1
itemthat may benefit from future review.
Items Recommended for Future Review
Q45
(r = 0)
I easily become frustrated and agitated over minor daily inconveniences.
The lowest item–total correlation was observed for Q45 ("I easily become frustrated and agitated over minor daily inconveniences."; r = 0.00), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice
A total of
296
participant responses were available for this assessment.
Dimension-level norms were calculated using
296
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.
