Can social support be improved in people with a severe mental illness? A systematic review and meta-analysis

Predictive factors and symptom severity spectrum in adult schizophrenia: Potential insights for improved management and adequate care

Schizophrenia is one of the most disabling psychiatric disorders characterized by positive (hallucinations, delusions, formal thinking disorder) and negative symptoms (anhedonia, lack of speech and motivation). The present study aimed to identify the predictive factors of schizophrenia in adults, and potential differences in the environment of origin, sex, levels of occupational stress, intellectual level, marital status and age of onset of the disease depending on the severity of symptoms using analysis of data collected from 120 patients with a diagnosis of schizophrenia. The study was conducted at the 'Prof. Dr. Alexandru Obregia' Clinical Psychiatric Hospital in Bucharest and included adult patients hospitalized between March 2018 and January 2021 diagnosed with schizophrenia and evaluated by general clinical examination, psychiatric, neurological and psychological evaluation. Results revealed that robust predictors of mild and moderate symptoms were affective symptoms, heredo-collateral history of schizophrenia, late onset, the presence of positive and negative symptoms, substance abuse, stress and marital status, unmarried, lower IQ and mental deficiency. For moderate-severe and severe symptoms, predictors were affective symptoms, heredo-collateral history of schizophrenia and affective disorders, substance abuse, stress, borderline IQ and mild mental deficiency. The present results can be used for further development of psychopharmacological management of schizophrenia.

Sources of social support and clinical and functional evolution of people with schizophrenia

PURPOSE

The impact of social support on comprehensive measures of results (clinical and functional) of the course of schizophrenia was studied, understood and evaluated as a multidimensional construct differentiating sources of support (family vs. nonfamily).

METHODS

One hundred fifty-two patients diagnosed with schizophrenia were assessed with the Mannheim Interview on Social Support (MISS) and the Social Functioning Scale (SFS). The hypotheses were explored in a prospective longitudinal design, using a causal correlational analysis for their evaluation by applying structural equation models.

RESULTS

The only explanatory factor of social functioning was Nonfamily social support, while the only explanatory factor of clinical result measurements was Family social support, observing a clearly differentiated impact of the different sources of support on the schizophrenia result measurements. It was also found that while Family social support explained 6.8% of the variance in the clinical result measurements, Nonfamily social support explained 13.7% of the variance in social functioning.

CONCLUSION

The results confirmed the differential importance of social support variables (family vs. nonfamily) in the clinical and functional result measurements of people with schizophrenia.

The effectiveness of an additive informal social network intervention for forensic psychiatric outpatients: results of a randomized controlled trial

Objectives

A supportive social network is associated with better mental health and wellbeing, and less criminal behavior. Therefore, this study examined the effectiveness of an additive informal social network intervention to treatment as usual (TAU) among forensic psychiatric outpatients.

Materials and methods

An randomized controlled trial (RCT) was conducted in forensic psychiatric care, allocating eligible outpatients (N = 102) to TAU with an additive informal social network intervention or TAU alone. Participants receiving the additive intervention were matched to a trained community volunteer over 12 months. TAU consisted of forensic care (e.g., cognitive behavioral therapy and/or forensic flexible assertive community treatment). Follow-up assessments were conducted at 3, 6, 9, 12, and 18 months after baseline. The primary outcome was the between-group effect on mental wellbeing at 12 months. Between-group effects on secondary outcomes (e.g., general psychiatric functioning, hospitalization, criminal behavior) were explored.

Results

Intention-to-treat analyses showed non-significant between-group effects on mental wellbeing on average over time and at 12 months. However, significant between-group effects were found on hospitalization duration and criminal behavior. Specifically, TAU participants were hospitalized 2.1 times more days within 12 months and 4.1 more days within 18 months than participants in the additive intervention. Furthermore, TAU participants reported 2.9 times more criminal behaviors on average over time. There were no significant effects on other outcomes. Exploratory analyses revealed that sex, comorbidity, and substance use disorders moderated effects.

Conclusion

This is the first RCT examining the effectiveness of an additive informal social network intervention in forensic psychiatric outpatients. Although no improvements were found on mental wellbeing, the additive intervention was effective in reducing hospitalization and criminal behavior. The findings suggest that forensic outpatient treatment can be optimized by collaborating with informal care initiatives aimed at improving social networks within the community. Future research is warranted to determine which specific patients might benefit from the intervention and if effects can be improved by extending the intervention duration and enhancing patient compliance.Clinical Trial Registration: [https://trialsearch.who.int/Trial2.aspx?TrialID=NTR7163], identifier [NTR7163].

Social Networks and Residential Status in Community-Dwelling Older Adults With Schizophrenia: Compensation by Reconfiguration?

OBJECTIVE

To address the paucity of data on the structure and content of social networks of older adults with schizophrenia (OAS).

METHODS

The OAS group comprised 249 persons aged 55 and older with early-onset schizophrenia living in supportive housing (SS; n = 151), independently (SI; n = 70), or with family (SF; n = 28). The community comparison (CC) group comprised 113 individuals. Social network analysis was used. Multinomial logistic regression with p ≤0.001 and p ≤0.05 was used for overall and pairwise comparisons, respectively.

RESULTS

Each OAS subgroup had more total, nonkin, and formal linkages than the CC group. The SS and SI subgroups had fewer kin linkages than the CC group. The CC group had more confidants than the SS subgroup, more reliable linkages than the SS and SI subgroups, and more sustenance linkages than each of the OAS subgroups. Nearly everyone in the CC, SI, and SF subgroups had a confidant, a reliable contact, and a sustenance linkage; 33% of the SS subgroup had no confidants. The SS subgroup displayed more psychiatric symptoms than the SI and SF subgroups. There were no differences in loneliness or relationship satisfaction between the CC and the schizophrenia subgroups.

CONCLUSION

Networks were expressed differentially across residential arrangements and differences may reflect dissimilarities in psychiatric functioning. OAS generally had ample levels of companionship and emotional and instrumental support, often comparable to their age peers. Whereas social networks typically decline at illness onset and may be predominantly family-focused, later life may be a time of network reconfiguration and reconstitution.
