A brief method for assessing expressed emotion in relatives of psychiatric patients

A measure of the attitudes and feelings that a relative expresses about a mentally ill family member, termed expressed emotion (EE), is derived from an extensive, semistructured interview, the Camberwell Family Interview (CFI). The present article describes a method for the assessment of EE attitudes that uses a variation of the 5-minute speech sample, originally developed by Gottschalk and Gleser (1969). The measure is derived from responses made by a patients key relative when prompted to give thoughts and feelings about the patient for a 5-minute period. A coding system was developed to score behaviors analogous to those rated on the CFI, such as criticism and emotional overinvolvement. The relationship between blind EE ratings derived from the 5-minute speech samples and those from the CFI was investigated with two separate samples of relatives of schizophrenics. The relationship between the sets of ratings was very close and supports the value of the 5-minute speech sample as a brief EE screening procedure.

Affective disorders in five United States communities

Results on the age/sex specific prevalence of DSM-III affective disorders from the NIMH Epidemiologic Catchment Area Study (ECA), a probability sample of over 18,000 adults from five United States communities, are presented. The cross-site means for bipolar disorder ranged from 0.7/100 (2 weeks) to 1.2/100 (lifetime), with a mean age of onset of 21 years and no sex difference in rates. The cross-site means for major depression ranged from 1.5/100 (2 weeks) to 4.4/100 (lifetime), with a mean age onset of 27 years and higher rates in women. The cross-site means for dysthymia, a chronic condition, was 3.1/100 with a higher rate in women. There was reasonable consistency in prevalence rates among sites. The implications of these findings for understanding psychopathology are discussed.

One‐month prevalence of mental disorders in the United States and sociodemographic characteristics: the Epidemiologic Catchment Area study

The associations between the one‐month prevalence rates of mental disorders and sociodemographic characteristics were investigated for 18571 people interviewed in the first‐wave community samples of all 5 sites in the US National Institute of Mental Health (NIMH) Epidemiologic Catchment Area program. Men were found to have a significantly higher rate of cognitive impairment than women after controlling for the effects of age, race or ethnicity, marital status and socioeconomic status. Marital status was one of the most powerful correlates of mental disorder risk: the odds of separated or divorced people having any NIMH Diagnostic Interview Schedule disorder were twice that of married people after controlling for age, gender, race or ethnicity and socioeconomic status. The odds of those in the lowest socioeconomic status group having any Diagnostic Interview Schedule disorder was about 2.5 times that of those in the highest socioeconomic status group, controlling for age, gender, race or ethnicity and marital status. For all disorders except cognitive impairment, race or ethnicity did not remain statistically significant after controlling for age, gender, marital status and socioeconomic status.

Somatic Symptom Index (ssi): A New and Abridged Somatization Construct: Prevalence and Epidemiological Correlates in Two Large Community Samples

An abridged somatization construct (the Somatic Symptom Index) derived from the Diagnostic Interview Schedules somatization disorder items was tested on community epidemiological samples to examine its prevalence, risk factors, and predictive value. The construct had a high prevalence (range, 4.4% to 20% compared with .03% to 0.7% for the full DSM-III somatization disorder diagnosis), was related to low socioeconomic status, female gender, older chronological age, and Hispanic ethnic background. The presence of this construct determined preferential use of medical services and predicted high indices of disability. The Somatic Symptom Index may have practical utility for clinical and community studies of somatoform phenomena.

Expressed emotion and schizophrenic outcome among Mexican-American families.

This study has demonstrated that among low-income, relatively unacculturated Mexican- American households, a high level of expressed emotion on the part of key relatives significantly increases the risk of relapse for remitted schizophrenics who return home to live with their families after hospital discharge. This cross-cultural replication of earlier research findings in London and southern California suggests that critical, hostile, or emotionally overinvolved attitudes and behaviors may be general major stressors that adversely influence the fragile adaptation of schizophrenic individuals in diverse cultural settings. The finding of a lower prevalence of high levels of expressed emotion among Mexican-American compared to Anglo-American and British households lends support to the hypothesis that intrafamilial behaviors may account for different schizophrenic outcomes in different cultures.

Measurement of Acculturation in a Community Population of Mexican Americans

A 26-item acculturation measure was administered to a probability sample of 1245 adult Mexican Americans residing in Los Angeles. This measure demonstrated high internal reliability for the total sample and for specific sex, educational, and language groups. Construct validity was supported by showing acculturation scores predicted length of exposure to U.S. culture. Data suggested that, among first generation Mexican Americans, those who were younger and male acculturated more rapidly than those who were older and female. This sex difference, but not the age difference, could be explained by educational and employment experiences. Among later generation Mexican Americans, those who were younger again had higher acculturation levels, possibly due to age differences in education and employment, or to historical factors differentially effecting age cohorts.

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.

An Attributional Analysis of Expressed Emotion in Mexican-American Families With Schizophrenia

In this study we tested an attributional model of expressed emotion (EE) among Mexican-American families. A sample of 46 key family members of schizophrenic patients were measured on three dimensions: affect toward patient, controllability attributions, and level of EE. Consistent with an attributional model, we found that high EE families (defined on the basis of critical comments) viewed the illness and associated symptoms as residing within the patients personal control, more so than did low EE families. We also found that attributions held by family members are related to their affective reactions. Specifically, family members who perceived the patient as having control over the symptoms of schizophrenia tended to express greater negative emotions such as anger and annoyance toward the patient than did family members who viewed the symptoms as beyond the patients personal control. An examination of the types of affects found and their relationship to EE status is discussed, along with implications for this research.

Factors Affecting the Probability of Use of General and Medical Health and Social/community Services for Mexican Americans and Non-hispanic Whites

Are individual characteristics associated with use of general and mental health and human service sectors similar for Mexican Americans (MAs) and non-Hispanic whites (NHWs)? We addressed this question using data from the Los Angeles site of the NIMH Epidemiologic Catchment Area Program. A random sample of the general population of two mental health catchment areas was interviewed in 1983-1984. With four exceptions, individual variation in sociodemographic factors, insurance coverage, and health status had similar effects on the probability of use of the general and mental health and human service sector for both NHWs and MAs. Recent psychiatric disorder was associated with greater use of general medical providers for mental health care for both NHWs and MAs, but significantly more so for NHWs. Female NHWs were more likely to use the human service sector (e.g., social service agencies) than male NHWs, but gender had no effect on this type of use for MAs. Higher job status was associated with greater use of outpatient general medical services, but significantly more so for NHWs than MAs. By contrast, having private health insurance was associated with a greater increase in use of outpatient general medical services for MAs than for NHWs.

Anxiety Disorders among Mexican Americans and Non-hispanic Whites in Los Angeles

This report from the Los Angeles site of the NIMH Epidemiologic Catchment Area study reveals significant ethnic and national origin differences in lifetime prevalence rates for three out of six specific, DSM-III-defined anxiety disorders. In the case of simple phobia, United States-born Mexican Americans report higher rates than native non-Hispanic whites or immigrant Mexican Americans, the latter two groups having similar rates. Mexican Americans born in the United States had higher rates of agoraphobia than immigrant Mexican Americans, and non-Hispanic whites reported higher lifetime rates of generalized anxiety disorder compared with both immigrant and native Mexican Americans. Neither ethnic nor national origin differences in lifetime prevalence rates were found for panic disorder, social phobia, and obsessive-compulsive disorder. Selective migration is postulated as a potential factor influencing prevalence differences between native and immigrant Mexican Americans.
