Psychosocial functioning as a mediator between childhood trauma and symptom severity in patients with schizophrenia.

BACKGROUND: There is empirical evidence that childhood trauma is associated with symptom severity and psychosocial functioning in schizophrenia. OBJECTIVE: The present study aimed to further elucidate these associations by examining which subdomains of schizophrenic symptoms and psychosocial functioning are associated with childhood trauma. In addition, it should be tested whether the association between childhood trauma and schizophrenic symptoms is mediated by psychosocial functioning. PARTICIPANTS AND SETTING: Participants of this study were 253 inpatients of five psychiatric hospitals diagnosed with schizophrenia. Clinical interviews were conducted with these patients towards the end of therapy. METHODS: Childhood trauma was assessed with the Childhood Trauma Questionnaire (CTQ), a retrospective self-report scale. Schizophrenic symptoms were measured with the Positive and Negative Syndrome Scale (PANSS) and psychosocial functioning with the Personal and Social Performance Scale (PSP), two measures for ratings by experts. RESULTS: Most participants were affected by childhood trauma, with 91.7 % reporting at least one trauma. Childhood trauma showed small but significant correlations with positive symptoms and general psychopathology, and also with psychosocial functioning in the occupational and social area and in control over aggressive behavior. Psychosocial functioning was shown to mediate the association between childhood trauma and symptom severity, whereby full mediation was found with regard to positive symptoms and partial mediation with regard to general psychopathology. CONCLUSIONS: The findings suggest that good psychosocial functioning mitigates the negative impact of childhood trauma on illness severity in schizophrenic patients. Therapeutic interventions that promote personal and social resources are therefore useful in the treatment of schizophrenia.

Joint Crisis Plans and Crisis Cards in Inpatient Psychiatric Treatment­a Multicenter Randomized Controlled Trial

BACKGROUND: Joint Crisis Plans (JCP) and crisis cards (CC) are both instruments designed to improve the management of future psychiatric crisis situations, but they differ, for example, in terms of resource use, legal validity, and aims. International research findings for JCP are inconsistent. METHODS: From January 2018 to December 2020, a single-blinded, two-armed multicenter RCT was carried out, with assessments at T0 (baseline) and T1 (18 months later). The patients included had schizophrenia or schizoaffective disorder and were aged between 18 and 62 years. The primary outcome was the cumulative duration of inpatient treatment (voluntary/involuntary), and coercive measures comprised the secondary outcome. Trial registration: DRKS00013985. RESULTS: Of the 266 study participants, 157 completed the study. In the CC group 57.8% and in the JCP group 64.9% were admitted to psychiatric hospitals between the index treatment and T1 (p = 0.367); 8.4% of the CC group and 12.2% of the JPC group were admitted against their will (p = 0.441). The cumulative treatment duration was not significantly shorter (p = 0.631) in the JPC group (mean 42.43 days, SD = 48.60) than in the CC group (50.16 days, SD = 74.16). Thus, JPCs did not achieve the expected improvement with regard to the primary endpoint. There were also no relevant differences regarding the secondary endpoint. Major effects in favor of the JCP were observed, however, in patients' development of conficence in the treatment teams and in their active participation in the treatment procedure. CONCLUSION: Although the study showed no superiority of JCP over CC with regard to the primary and secondary outcomes, JCP should be used more frequently in routine practice as an intervention to support a participative approach to treatment.

Psychosocial functioning as a personal resource promoting a milder course of schizophrenia.

Schizophrenia has been shown repeatedly to be associated with a low level of psychosocial functioning. It is assumable that psychosocial functioning is related not only to current, but also to future symptom severity. To test this assumption, a follow-up study with two measurement time points with an interval of 18 months was conducted. In total, 154 inpatients from five psychiatric hospitals with a diagnosis of a schizophrenic disorder took part at both visits. Psychosocial functioning was measured with the Personal and Social Performance Scale (PSP scale) at baseline, and schizophrenic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS) at baseline and at follow-up. Two PSP subscales, i.e. socially useful activities and control over disturbing and aggressive behavior, turned out to be significant predictors of symptom severity 18 months later. The findings reveal that personal resources in the occupational domain and in adequate interpersonal behavior can have a positive impact on the long-term course of schizophrenia.
