A comparison of patient ratings and staff ratings of disability using the World Health Organisation Disability Assessment Schedule in individuals with psychotic spectrum disorders who are forensic psychiatric inpatients.

BACKGROUND: Psychosocial rehabilitation in forensic psychiatric services requires sound measurement of patient and staff perceptions of psychosocial function. The recommended World Health Organisation Disability Assessment Schedule 2.0 (WHODAS), designed for this, has not been examined with offender patients. AIMS: To examine patient and staff WHODAS ratings of secure hospital inpatients with psychosis, any differences between them and explore associations with other clinical factors. METHODS: Seventy-three patients self-rated on the WHODAS after 3 months as inpatients. An occupational therapist interviewed the patient's primary nurse and care team at about the same time (staff ratings). Scores were calculated according to the WHODAS manual. WHODAS scores and interview-rated symptom severity, cognitive measures, daily antipsychotic dose and duration of care were compared. RESULTS: Patient ratings indicated less disability than staff ratings for total score and for the domains of understanding and communicating, getting along and life activities. Self-care and participation ratings were similar. Patients were more likely to rate themselves as disabled in getting around (mobility). Only one-fifth of patient- and staff- ratings (16, 22%) were similar, while for nearly a third of the patients (23, 32%) self-ratings were higher than staff ratings. More severe positive symptoms were associated with higher self-rated WHODAS disability after accounting for treatment duration, negative symptoms, cognitive score and antipsychotic dose. No variable accounted for the staff/patient differences in ratings. CONCLUSION: Our mean WHODAS score findings echoed those in other patient samples-of patient underestimation of disability, linked to severity of symptoms. In this study using the WHODAS for the first time in a forensic mental health secure inpatient service, however, we found that, by comparing individuals, half of the patients reported equivalent or greater disability than did staff. Future research should focus on elucidating from patients what contributes to their self-ratings. Understanding their thought processes in rating may enhance rehabilitation planning.

Cognition, prior aggression, and psychopathic traits in relation to impaired multimodal emotion recognition in psychotic spectrum disorders.

Background: Psychopathic traits have been associated with impaired emotion recognition in criminal, clinical and community samples. A recent study however, suggested that cognitive impairment reduced the relationship between psychopathy and emotion recognition. We therefore investigated if reasoning ability and psychomotor speed were impacting emotion recognition in individuals with psychotic spectrum disorders (PSD) with and without a history of aggression, as well as in healthy individuals, more than self-rated psychopathy ratings on the Triarchic Psychopathy Measure (TriPM). Methods: Eighty individuals with PSD (schizophrenia, schizoaffective disorder, delusional disorder, other psychoses, psychotic bipolar disorder) and documented history of aggression (PSD+Agg) were compared with 54 individuals with PSD without prior aggression (PSD-Agg) and with 86 healthy individuals on the Emotion Recognition Assessment in Multiple Modalities (ERAM test). Individuals were psychiatrically stable and in remission from possible substance use disorders. Scaled scores on matrix reasoning, averages of dominant hand psychomotor speed and self-rated TriPM scores were obtained. Results: Associations existed between low reasoning ability, low psychomotor speed, patient status and prior aggression with total accuracy on the ERAM test. PSD groups performed worse than the healthy group. Whole group correlations between total and subscale scores of TriPM to ERAM were found, but no associations with TriPM scores within each group or in general linear models when accounting for reasoning ability, psychomotor speed, understanding of emotion words and prior aggression. Conclusion: Self-rated psychopathy was not independently linked to emotion recognition in PSD groups when considering prior aggression, patient status, reasoning ability, psychomotor speed and emotion word understanding.
