Global Participation Chart Participants US 2 #1 HK 1 #2 IN 1 #3 SG 1 #4 CN 1 #5
Global Participation Interpretation

The current dataset includes responses from 5countries . The largest contribution currently comes from US which represents approximately 33.3% of all participants. International participation enhances sample diversity and improves the generalizability of normative findings across geographic regions.

Normative Percentile Distribution

Population Median 10th Percentile 20 Population Median 25th Percentile 66 Population Median 50th Percentile 71 Population Median 75th Percentile 76 Population Median 90th Percentile 90
Normative Interpretation

The current normative dataset indicates that approximately 10% of participants scored below 20%, while 90% scored above this level. The median score was 71%, meaning that half of participants scored below this value and half scored above it. Scores of 76% or greater were achieved by approximately the highest 25% of participants, whereas scores of 90% or greater were achieved by approximately the highest 10% of participants. These percentile values provide preliminary normative benchmarks that can be used to contextualize individual assessment results relative to the current community sample.

Distribution Histogram

20-29 1 60-69 1 70-79 2 90-99 2
Distribution Interpretation

This histogram displays the distribution of participant scores across the assessment. A balanced bell-shaped pattern generally indicates good score dispersion and stronger normative utility, whereas highly skewed distributions may indicate floor effects, ceiling effects, or sample bias.

Distribution Quality

The score distribution demonstrated a skewness of -1.46 and a kurtosis of 2.71.

The distribution demonstrates mild departures from normality, although the overall score pattern remains broadly interpretable for preliminary normative purposes.

Reliability Analysis

0.951 Poor Acceptable Good Excellent

EXCELLENT RELIABILITY

The assessment demonstrated excellent internal consistency reliability (Cronbach's α = 0.951), suggesting that the assessment items measure a relatively coherent psychological construct.

Item–Total Correlations

Insufficient Sample Size

Item–total correlations are not currently reported because the assessment has fewer than 100 participant responses. Psychometric item analysis requires a larger sample to produce stable and interpretable estimates.

Current Participants: 6
Minimum Recommended: 100

Dimension Norms

Dimension Profile Mean SD 50% Emotional Shopping 75.8% 29.4 Shopping Preoccupation 74.2% 28.9 Loss of Control 69.8% 27.1 Shopping Consequences 68.5% 26.9 Withdrawal Reactions 65.8% 28
Dimension Interpretation

The highest scoring dimension in the current sample was Emotional Shopping (75.8%). The lowest scoring dimension was Withdrawal Reactions (65.8%). Dimensions located above the 50% reference line represent characteristics that were more strongly endorsed within the current participant sample. Standard deviations indicate the degree of variability observed across participant responses.

Research Interpretation

This psychometric dataset currently includes 6 anonymous participant responses collected through voluntary participation. The observed mean score was 70 with a standard deviation of 27.14, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated excellent reliability (Cronbach alpha = 0.951). Observed skewness (-1.46) and kurtosis (2.71) were examined as indicators of distribution quality. The distribution demonstrated mild departures from normality, although the overall score pattern remained broadly interpretable for preliminary normative purposes.

Ethical & Research Notice

All responses included in this dataset are collected anonymously through voluntary participation. No personally identifying information is stored. Results are intended exclusively for educational, psychometric, research, and self-reflective purposes and should not be used as clinical diagnoses. Trait Profiler continuously monitors response quality, distribution stability, and internal consistency to support ethical psychometric reporting.
