Psychosis Symptom Rating Scale Structure n Modeled after

Psychosis Symptom Rating Scale

Structure n Modeled after Psychopathy Check List – R n 20 “factors” deemed relevant to psychopathy n Clinicians rate evidence of factors (0 -1 -2 scale) n Total score, cutoff score structure (various norms) n Stimulated many clinical, research studies n Avoids complexities of testing patient directly n Data taken from records and interview n Longer term evidence; not a “snapshot”

Main Research Questions n Can it reliably differentiate psychotic from non -psychotic patients in “blind” samples (where psychosis is currently diagnosed by clinicians who are in agreement)? n Can it avoid mislabeling non-psychotic deaf individuals with limited or atypical sign language abilities? n Calculate norms and inter-rater reliability

Current Status n Psychosis-Deaf list serve established n psychosis-deaf-subscribe@yahoogroups. com n Literature review conducted n First draft in development n National conference proposed funder being pursued) (new

Next Steps n Complete draft one n Get Psychosis-deaf feedback n Revise to yield first prototype n Test prototype at DWC n Revise prototype n Administer prototype with collaborators n Feedback and revision again n Administer with new collaborator group

Future Research n Useful with undiagnosed patients? n Predictive or reflective of treatment responses? n Useful with populations of various sign language fluency? Oral deaf? H-O-H? n Various normative groups’ performance? n Other…?
