This study examined whether the sociocultural context moderates the relationship between families' expressed emotion (EE) and clinical outcomes in schizophrenia. In a sample of 60 Mexican American caregivers and their ill relatives, we first assessed whether EE and its indices (criticism, emotional overinvolvement [EOI], and warmth) related to relapse. Second, we extended the analysis of EE and its indices to a longitudinal assessment of symptomatology. Last, we tested whether bidimensional acculturation moderated the relationship between EE (and its indices) and both relapse and symptom trajectory over time. Results indicated that EOI was associated with increased relapse and that criticism was associated with increased symptomatology. Additionally, as patients' Mexican enculturation (Spanish language and media involvement) decreased, EE was increasingly related to relapse. For symptomatology, as patients' U.S. acculturation (English language and media involvement) increased, EE was associated with increased symptoms longitudinally. Our results replicate and extend past research on how culture might shape the way family factors relate to the course of schizophrenia.

    • "Although there is mixed evidence with regard to whether the global EE construct (i.e., high EE versus low EE) predicts relapse for Mexican-Americans (Karno et al., 1987; Kopelowicz et al., 2006) or does not predict relapse for Mexican-Americans (Aguilera et al., 2010; Kopelowicz et al., 2002), the EE index of EOI is a reliable predictor of relapse among Mexican-Americans (Aguilera et al., 2010; Breitborde et al., 2007). Of note, the EE index of criticism does not predict relapse among Mexican-Americans (Aguilera et al., 2010; Kopelowicz et al., 2002; López et al., 2004). Previously, Breitborde et al. (2007) found that a curvilinear model best fits the relationship between EOI and relapse among Mexican-Americans, among whom high EOI was associated with a greater than average risk for relapse and moderate EOI was associated with a lower than average risk for relapse.

    ABSTRACT: Although it is clear that expressed emotion (EE) is associated with the course of schizophrenia, proposed models for this association have struggled to account for the relationship between the EE index of emotional overinvolvement (EOI) and relapse. To expand our understanding of the EOI-relapse association, we first attempted to replicate the finding that the EOI-relapse association is curvilinear among 55 Mexican-Americans with schizophrenia and their caregiving relatives. Second, we evaluated whether the caregivers' perception of their ill relative's efficacy may account for the EOI-relapse association. Our results comport with past findings with regard to the curvilinear nature of the EOI-relapse association among Mexican-Americans and suggest that EOI may only seem to be a risk factor of relapse because of its strong association with a true risk factor for relapse (i.e., caregivers' perception of their ill relative's efficacy).

    ABSTRACT: Schizophrenia is a chronic psychiatric disorder that affects 1% of the world's population. Family interventions whereby the patients and their relatives can attend psychiatric therapy sessions are effective at preventing relapse of symptoms. In a country such as South Africa where there has been a shift from institutionalisation to community care, family therapy treatment models are an important option to explore. Although there is a paucity of research on family therapy for schizophrenia in the South African context, we found a number of studies conducted in both developed and developing countries. Problems with adherence to medication, lack of psychoeducation and low expressed emotion (EE) were identified as challenges to effective family therapy models. A country such as South Africa has additional challenges of stigmatisation of mental illness as well as cultural perceptions of illness that may influence barriers to mental health care. These should be considered when designing family therapy interventions. We suggest further research endeavour to explore the applicability of family therapy models for people living with schizophrenia in South Africa. EE in relation to different cultural groups in South Africa should be considered.

    ABSTRACT: The incidence of schizophrenia, as well as the symptoms, course, and outcomes for people so diagnosed seem to vary across some cultural contexts. The mechanisms by which cultural variations may protect one from or increase one's risk of developing schizophrenia remain unclear. Recent findings from transdisciplinary cross-cultural research, indicate ways that we may better understand how socioenvironmental and cultural variables interact with physiologic pathways relating psychosocial stress and psychotic symptoms, epigenetic changes, and people's use of culturally available tools to mitigate stress, in ways that may inform relevant, effective interventions for people diagnosed with psychotic disorders worldwide.
