M219. OVERESTIMATING FUNCTION – A RISK FACTOR FOR SUBOPTIMAL COMMUNITY AID IN SCHIZOPHRENIA

Abstract

BackgroundPatients with schizophrenia have difficulties in judging their own performance. Patients with no or little practical experience of demands from active performance in society tends to overestimate their ability. Research has also found that patients who overestimate their function also runs a risk to be perceived as better functioning than what they actually are when judged by caregivers. The aim with this study is to examine if patients who overestimate their ability will receive less community support compared to patients who have an accurate perception of their ability?MethodsThe study population was 184 patients with schizophrenia spectrum disorder. They were tested with the Swedish version of the UCSD Performance-based Skills Assessment–Brief Version (UPSA-B). Before the test they were asked how they thought their functioning were in four different domains covered in the UPSA-B. After the test they were divided into four groups: “Good functioning with realistic perception”, “Good functioning but underestimating their function”, “Impaired function with realistic perception” and “Impaired function but overestimating their performance”. The amount of received community support were investigated and related to patients′ actual performance and self-perception.ResultsAnalyzes showed that patients who had an impaired function and a realistic view of their ability had more support than those who were impaired but overestimated their ability. Also, patients with good functioning but underestimating their performance had more support than those who had a good ability and a realistic perception. Finally, there were no difference in community support to the patients in the two groups “Good function with realistic perception” and “Impaired function but overestimating their performance”.DiscussionOur results indicate that patients with impaired functioning who overestimate their ability risk an insufficient community support. This in combination with earlier findings, that staff-members in psychiatric out-patient settings are likely to base their judgement on patients′ report consequential leading to false positive conclusions, may have both short- and long-term implications. Not achieving symptomatic remission, as a consequence of inability to follow medical prescriptions, and sub-optimal social functioning with isolation are two possible implications. The findings once again raises the need for the testing of patients′ function instead of only conducting interviews.
