Administer the interview and retain the source-specific symptom definitions, probes and anchors. Rate items 1–10 from the individual’s self-report and items 11–18 from observed behavior and speech. Consult Ventura and colleagues’ administration guidelines before use. This protocol uses the PhenX Working Group’s recommended 0–6 coding. Leave an unassessed item unanswered; it is not zero. This website requires all 18 ratings before calculating a total and does not impute omitted observations.
01 Somatic Concern Degree of concern over present bodily health. Rate the degree to which physical health is perceived as a problem by the individual, whether complaints have realistic bases or not. Somatic delusions should be rated in the severe range with or without somatic concern.

09 Unusual thought content Unusual, odd, strange, or bizarre thought content. Rate the degree of unusualness, not the degree of disorganisation of speech.
