title: Self-Appraisal of Illness Questionnaire (SAIQ): relationship to researcher-rated insight and neuropsychological function in schizophrenia.
abstract: The Self-Appraisal of Illness Questionnaire (SAIQ) is a self-report instrument designed to assess attitudes toward mental illness among persons receiving psychiatric treatment. This instrument was developed for use in community settings, adapted closely from the Patient's Experience of Hospitalization questionnaire. In order to examine the validity of the SAIQ, a factor analysis was first conducted on the items of this instrument in a sample of 59 outpatients with schizophrenia or schizoaffective illness. Three factors emerged: Need for Treatment, Worry, and Presence/Outcome of Illness. Next, to examine the concurrent validity of these three SAIQ subscales, they were correlated with researcher rated insight scales and neuropsychological tests. Results indicated that the Need for Treatment and Presence/Outcome subscales were significantly correlated with both researcher-rated insight scales and with neuropsychological tests of executive functioning. The Worry subscale was not associated with either researcher-rated insight scales or neuropsychological tests. It was concluded that the Need for Treatment and Presence/Outcome subscales may be used in combination as a brief screening instrument for clients with schizophrenia receiving outpatient psychiatric treatment who may be at risk for treatment non-compliance due to a lack of insight into illness.
