Schizoid-Avoidant Distinction Test
SADT — Differential Battery · Social Disinterest vs. Social Anxiety
Five-measure differential battery resolving one of personality assessment's toughest distinctions: true social disinterest (schizoid) vs. social anxiety with desire for connection (avoidant). Based on Winarick & Bornstein (2015) empirical research.
At a glance
The five measures
Revised Social Anhedonia Scale Schizoid
Chapman et al. Measures social anhedonia — the absence of pleasure in social contexts. Elevated RSAS uniquely predicts schizoid features in regression, controlling for avoidant indicators.
Need to Belong Scale Avoidant
Leary et al. Low N2B predicts schizoid features; high N2B combined with high shame and rejection sensitivity predicts avoidant features.
Internalized Shame Scale Avoidant
Cook. Measures shame as a stable internal state. Uniquely predicts avoidant features in the Winarick & Bornstein (2015) regression model.
Rejection Sensitivity Questionnaire Avoidant
Downey & Feldman. Measures anxious expectation of, and overreaction to, rejection. Uniquely predicts avoidant features; non-significant for schizoid features.
Schizoid-40 (Winarick) Schizoid
Winarick. Targeted schizoid personality feature index. Anchors the differential scoring profile alongside the RSAS.
Sample battery results
| Scale | Raw | Z-Score | Percentile | Interpretation |
|---|---|---|---|---|
| RSAS (Social Anhedonia) | 28 | +1.8 | 96th | Elevated |
| ISS (Internalized Shame) | 42 | −0.3 | 38th | Average |
| RSQ (Rejection Sensitivity) | 6.2 | −0.5 | 31st | Low Average |
| N2B (Need to Belong) | 18 | −1.2 | 12th | Low |
Pattern classification: Schizoid — elevated social anhedonia with low belonging drive and low rejection sensitivity. Sample data only.
