Toward specifying the nature of the relationship between expressed emotion and schizophrenic relapse: the utility of curvilinear models.

Although expressed emotion (EE) has been demonstrated to be associated with the course of schizophrenia, the nature of this relationship is unclear. This study proposes that testing for curvilinear relationships can identify the specific nature of the relationships between EE indices and relapse. The utility of curvilinear models was explored through a reanalysis of data from a prior study of EE among Mexican-Americans (Karno et al., 1987). The results suggest that the relationship between the EE index of emotional overinvolvement (EOI) and relapse is curvilinear and that high levels of EOI may exert a toxic effect on course of illness whereas medium levels of EOI may be protective. The relationship between the EE index of warmth and relapse is also curvilinear and high levels of warmth appear to exert a protective effect on the course of illness. The role of culture is explored in explaining the specific manner in which EE relates to relapse among Mexican-Americans.

Research issues for improving treatment of U.S. Hispanics with persistent mental disorders.

This article reports on the outcome of an expert consensus meeting in August 2005 sponsored by the National Institute of Mental Health, which assembled 15 senior researchers with a background in treatment and services research with the Hispanic population. The purpose of the workshop was to identify research issues most pertinent for improving quality and effectiveness of treatment for Hispanics experiencing persistent mental disorders, defined as psychiatric syndromes that are of sufficient severity and duration to cause long-term impairment in social and occupational functioning and significant disability. The spectrum of ideas and recommendations advanced at the one-day meeting was wide and overlapping; therefore, the rich body of material was subsequently organized into five topics: diagnosis, quality of care and culturally appropriate services, psychosocial intervention development, psychopharmacologic interventions, and access to care. Although the authors recognize that the review was broad and the agenda presented is ambitious and in many instances generalizes to priority areas in overall mental health services and treatment research, the recommendations are intended to stimulate research for addressing the unique problems and research deficits that affect Hispanics with persistent mental disorders.

Ethnicity, expressed emotion, attributions, and course of schizophrenia: family warmth matters.

The authors examined the role of family factors and the course of schizophrenia by carrying out additional assessments and analyses in 2 previously published studies of Mexican American and Anglo American patients and families. The authors found partial support for an attributional model of relapse for families who are low in emotional overinvolvement. Attributions of control, criticism, and warmth together marginally predicted relapse. The data also indicated that for Mexican Americans, family warmth is a significant protective factor, whereas for Anglo Americans, family criticism is a significant risk factor. These findings suggest that the sociocultural context shapes the pathways by which family processes are related to the course of illness. Moreover, the warmth findings suggest that families may contribute to preventing relapse.
