Winarick Test of Schizoid Patterns
A 40-item public-domain IPIP self-report measure of schizoid personality patterns across five domains — Social Withdrawal, Emotional Constriction, Inner Fantasy, Anhedonia, and Social Indifference — plus an overall load. Research and educational use only; not a clinical diagnostic tool.
This is a clinical instrument. It is not publicly self-administered — a clinician assigns it through a secure patient link.
At a glance
What it measures
This is a construct-descriptive, clean-room measure of the schizoid pattern built from public-domain International Personality Item Pool (IPIP) items. It is not the Revised Social Anhedonia Scale and does not reproduce or inherit that instrument's items or validity data; it was assembled independently to profile schizoid tendencies across several facets rather than as a single screening total.
The 40 items resolve into five construct facets — Social Withdrawal, Emotional Constriction, Inner Fantasy, Anhedonia, and Social Indifference — plus an overall schizoid-load composite. Each facet is reported non-diagnostically as a standing relative to a reference sample, not as a clinical determination.
How to read it
Facet standings are expressed as population percentiles against the developer's reference sample. The instrument is administered by a clinician through a secure patient link rather than the open self-serve catalog. A high or low standing on any facet describes a self-reported tendency; it is not a diagnosis and does not substitute for clinical evaluation.
Subscales
Social Withdrawal 12 items
how much you prefer solitude and limit time spent with others
Emotional Constriction 8 items
how much you hold back emotional expression and keep feelings private
Inner Fantasy 6 items
how absorbed you become in your own inner world of thought and daydream
Anhedonia 7 items
how much pleasure you take from everyday activities and the senses
Social Indifference 7 items
how indifferent you are to praise, criticism, and others' opinions
Example item
“I love to chat.”
Illustrative only. During administration items are presented one screen-set at a time; response-key direction is never shown to respondents.
Scoring & interpretation
Item responses are summed within each scale (reverse-keyed items recoded first) and expressed as a population percentile against the cited reference sample, with a reliability-based confidence range where α is published.

Winarick, D.J. (Dwinarick Research Sample, N = 551). Test of Schizoid Patterns: five domain raw sums (40 items, 1–5; reverse-keyed items: 6−r). Responses collected in a 9-level agree–disagree format and mapped to standard IPIP 1–5 scoring. Overall α = .90 (published = .89, N = 555). Per-domain α: SW = .87, EC = .79, IF = .65, AN = .54, SI = .59. Confidence range uses the standard error of measurement (SEM = SD·√(1−α)) from the computed α.
