Deenz IEA Personality Inventory (DIEA)
normative dataset currently contains
140
participant records collected between
Jun 11, 2026
and
Jun 27, 2026
.
This psychometric dataset currently includes 140 anonymous participant responses collected through voluntary participation. The observed mean score was 49.74 with a standard deviation of 10.94, indicating moderate score variability within the sampled population. Internal consistency reliability analysis produced a Cronbach alpha of 0.461, which falls below commonly accepted psychometric standards and should be interpreted cautiously until additional data are collected. Observed skewness (-0.29) and kurtosis (0.2) 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 = 0.08)
Friends say I don’t talk much at parties.
Q2
(r = 0.2)
I hate deep talks.
Q4
(r = 0.07)
I usually follow back the people who follow me.
Q5
(r = -0.31)
I find it hard to sit quietly.
Q6
(r = -0.33)
I prefer new friends to old ones.
Q7
(r = 0.29)
I like spending time alone.
Q8
(r = -0.15)
I enjoy being noticed.
Q9
(r = 0.27)
I hate quiet/shy people.
Q11
(r = 0.26)
I feel people are watching me when I go out.
Q12
(r = -0.14)
I hate sitting quietly for too long.
Q15
(r = -0.05)
People say I talk a lot.
Q18
(r = 0.05)
I speak first and think later.
The lowest item–total correlation was observed for Q6 ("I prefer new friends to old ones."; r = -0.33), indicating comparatively weaker alignment with the overall construct.

Normative Data Notice
A total of
140
participant responses were available for this assessment.
Dimension-level norms were calculated using
67
valid response records.
Approximately
73
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.
