The relationship between relative's Expressed Emotion and schizophrenic relapse: an Australian replication

The predictive power of expressed emotion and its components in relapse of schizophrenia: a meta-analysis and meta-regression

BACKGROUND

Schizophrenia is a longstanding condition and most patients experience multiple relapse in the course of the condition. High expressed emotion (HEE) has been found to be a predictor of relapse. This meta-analysis and meta-regression examined the association of global EE and relapse specifically focusing on timing of relapse and EE domains.

METHODS

Random-effects model was used to pool the effect estimates. Multiple random-effects meta-regression was used to compute the moderator analysis. Putative effect moderators including culture, EE measurements, age, length of condition and study quality were included.

RESULTS

Thirty-three prospective cohort studies comprising 2284 patients were included in the descriptive review and 30 studies were included for meta-analysis and meta-regression. Findings revealed that global HEE significantly predicted more on early relapse (⩽12 months) [OR 4.87 (95% CI 3.22-7.36)] than that on late relapse (>12 months) [OR 2.13 (95% CI 1.36-3.35)]. Higher level of critical comments (CC) significantly predicted relapse [OR 2.22 (95% CI 1.16-4.26)], whereas higher level of warmth significantly protected patients from relapse [OR 0.35 (95% CI 0.15-0.85)]. None of the moderators included significantly change the results.

CONCLUSIONS

These findings indicate that there is a dynamic interaction between EE-relapse association with time, and CC and warmth are the two important EE domains to influence relapse among patients with schizophrenia. Results also confirmed the foci of family interventions on reducing CC and improving warmth in relationship.

Are family warmth and positive remarks related to outcomes in psychosis? A systematic review

BACKGROUND

Affective attitudes and behaviours manifested within the family environment have been characterised as expressed emotion (EE). High EE environments have been robustly shown to put psychosis patients at a greater risk of relapse compared with low EE exposure. Positive EE dimensions (warmth; positive remarks) have received far less attention than negative EE dimensions such that EE has become synonymous with a negative family atmosphere; the predictive value of positive EE dimensions is largely ignored. A systematic review examining the relationship between positive family EE and outcomes in psychosis is needed.

METHODS

A systematic search was conducted. Studies reporting bias and study quality were assessed.

RESULTS

A total of 2368 studies were identified. Of these, 27 met eligibility criteria reporting outcomes including relapse, symptomatology, social functioning and life satisfaction. Relapse was the most commonly measured outcome. Stronger evidence emerged for the association between EE warmth and outcomes compared with EE positive remarks, with effects mostly evident in the early phase of psychosis. Evidence for protective effects of warmth on relapse was found up to 9 months follow-up. No effects were evident between positive remarks and relapse. Studies assessing symptom outcomes showed inconsistent findings. Evidence for an association with social functioning was evident, primarily in at risk mental states. Warmth and positive remarks predicted life satisfaction.

CONCLUSIONS

The positive aspects of EE require further investigation with longitudinal research designs. Clinical interventions should focus not only on reducing negative aspects of EE but also foster warmth within families in the context of psychosis.

Expressed emotion and socio-demographic and clinical factors in families of Brazilian patients with schizophrenia

BACKGROUND

Families are the main caregivers of people with schizophrenia. Family dynamic and expressed emotion (EE) of relatives are fundamental determinants on the course of schizophrenia.

METHOD

This study analyzed socio-demographic and clinical factors related to EE components. A total of 94 dyads (patients with schizophrenia and their relatives) were recruited from three mental health clinics. A form containing socio-demographic and clinical variables and the Brazilian version of Family Questionnaire were used and the data were analyzed through regression model.

RESULTS

Results showed that factors such as patients' occupation status and patients' age, as well as relatives' gender and the degree of relatedness, were related to emotional overinvolvement and critical comments levels.

CONCLUSION

This is the first study in the Brazilian cultural context that evaluates EE components and related factors on families of patients with schizophrenia. Other studies concerning EE on different cultural contexts and possible interventions must be carried out to help health professionals to improve patient and family care.

Expressed emotion across cultures

Expressed emotion has been used as a construct in understanding the interaction between patients and their carers and families. A considerable amount of data from Western cultures suggests that high expressed emotion can lead to relapse in vulnerable individuals, even when they are on medication. However, the data from other cultures are less solid. This paper reviews some of the existing findings and recommends that various components of expressed emotion must be seen in the cultural context and embedded in the normative data of the population before the concept can be considered in association with the pathogenesis of relapse.

Integrity of Literature on Expressed Emotion and Relapse in Patients with Schizophrenia Verified by a p-Curve Analysis

There is growing concern that much published research may have questionable validity due to phenomena such as publication bias and p-hacking. Within the psychiatric literature, the construct of expressed emotion (EE) is widely assumed to be a reliable predictor of relapse across a range of mental illnesses. EE is an index of the family climate, measuring how critical, hostile, and overinvolved a family member is toward a mentally ill patient. No study to date has examined the evidential value of this body of research as a whole. That is to say, although many studies have shown a link between EE and symptom relapse, the integrity of the literature from which this claim is derived has not been tested. In an effort to confirm the integrity of the literature of EE predicting psychiatric relapse in patients with schizophrenia, we conducted a p-curve analysis on all known studies examining EE (using the Camberwell Family Interview) to predict psychiatric relapse over a 9- to 12-month follow-up period. Results suggest that the body of literature on EE is unbiased and has integrity, as there was a significant right skew of p-values, a nonsignificant left skew of p-values, and a nonsignificant test of flatness. We conclude that EE is a robust and valuable predictor of symptom relapse in schizophrenia.

Identifying the socio-demographic and clinical determinants of family functioning in Greek patients with psychosis

BACKGROUND

Studies on determinants affecting family functioning of patients with psychosis are still limited in Greece.

AIM

The aim of this study was to describe the socio-demographic and clinical characteristics associated with family functioning in patients with schizophrenia and bipolar disorder in Crete, Greece.

METHODS

A total of 100 patients and their caregivers agreed to participate in the study. Family functioning was assessed in terms of cohesion, adaptability, communication and satisfaction dimensions (Family Adaptability and Cohesion Evaluation Scale IV Package), expressed emotion (Family Questionnaire), family burden (Family Burden Scale) and caregivers' psychological distress (General Health Questionnaire-28). Multivariate linear regression models were implemented to examine the associations between each one of the family measures and different social and clinical characteristics.

RESULTS

With regard to the caregivers' characteristics, gender, employment status, origin, residence, financial status, relation to the patient, contact with the patient and family structure were among the most significant determinants of family functioning. Also, patients' socio-demographic characteristics, including age, education, origin, residence and employment status, as well as illness-related factors, such as onset of mental illness, number of hospitalisations, last hospitalisation, longer hospitalisation and clinical diagnosis impacted intrafamilial relationships.

CONCLUSION

The results of this study suggest that a number of social and clinical factors contributed to the family environment of patients with psychosis. Identifying the determinants of family functioning in psychosis is instrumental in developing understandings regarding the factors which may contribute to the rehabilitation or relapse of the patient and the support required to strengthen positive family interactions.

The Therapist—Patient Relationship with Schizophrenic Patients

Schizophrenic patients seem to react sensitively to expressed affect. Expressed emotion research has shown the negative impact of specific family communication styles on the course of illness. This paper reviews and discusses related research on the therapist–patient relationship. Two studies by the author are presented. The first study is an examination of therapist rating of the therapist–patient relationship, the interaction between therapist's ratings and patient's psychopathology, and the prediction of the course of illness from therapist ratings. The second study assesses the therapist–relative–patient triad using EE measures, as well as dyadic assessment of the therapist–patient relationship.

Cross-cultural adaptation and validation of the Greek version of the Family Questionnaire for assessing expressed emotion

Expressed emotion (EE) has proved to be an established factor in short-term relapse in schizophrenia. The aim of the present study was to examine the psychometric properties of the Greek version of the Family Questionnaire (FQ), a brief self-report questionnaire measuring the EE status of relatives of patients with schizophrenia in terms of criticism (CC) and emotional overinvolvement (EOI). The translated and adapted 20-item FQ was administered to 176 family caregivers of patients with schizophrenia and bipolar disorder. Caregivers' burden (Family Burden Scale) and psychological distress (General Health Questionnaire-28) were also evaluated. The findings indicated that the Greek version displays a two-factor structure with two subscales of EE-CC and EOI-with 10 items each, similarly to the original version. The convergent validity of the subscales was highly supported by correlations with caregivers' burden and psychological distress. The Cronbach's α coefficient measuring internal consistency for the two scales were 0.90 for CC and 0.82 for EOI. The test-retest correlation coefficients measuring reproducibility were 0.99 and 0.98 for CC and EOI, respectively. The Greek version of the FQ appears to be a valid and reliable instrument to be used in both research and clinical assessment of family EE.

Cultural specificity of emotional overinvolvement: a systematic review

Understanding cross-cultural aspects of emotional overinvolvement (EOI) on psychosis outcomes is important for ensuring cultural appropriateness of family interventions. This systematic review explores whether EOI has similar impact in different cultural groups and whether the same norms can be used to measure EOI across cultures. Thirty-four studies were found that have investigated the impact of EOI on outcomes across cultures or culturally adapted EOI measures. The relationship between high EOI and poor outcome is inconsistent across cultures. Attempts to improve predictive ability by post hoc adjustment of EOI norms have had varied success. Few studies have attempted a priori adaptations or development of culture-specific norms. Methodological differences such as use of different expressed emotions (EE) measures and varying definitions of relapse across studies may explain a lack of EOI outcome relationship across cultures. However, our findings suggest that the construct and measurement of EOI itself are culture-specific. EOI may not necessarily be detrimental in all cultures. The effect of high EOI may be moderated by the unexplored dimension of warmth and high levels of mutual interdependence in kin relationships. Researchers should reevaluate the prevailing concepts of the impact of family relations on the course and outcome of psychotic disorders, specifically focusing on the protective aspects of family involvement. Clinically, family interventions based on EE reduction should take cultural differences into account when treating families from different ethnocultural groups.

Factors associated with relapse in patients with schizophrenia

OBJECTIVE

To assess risk factors for relapse in patients with schizophrenia attended in daily practice.

METHODS

Patients with schizophrenia admitted consecutively to short-stay/acute-care psychiatric units over a 6-month period were eligible. Variables statistically significant in the univariate logistic regression analysis were then subjected to multivariate analysis.

RESULTS

The study population included 1646 patients (67.6% men). In the univariate analysis, low family support, duration of illness > 5 years, number of previous hospitalizations, cocaine and cannabis consumption, and number of different antipsychotic drug classes were risk factors for relapse. In the multivariate analysis, number of previous hospitalizations (odds ratio [OR] 1.29, 95% confidence interval [CI] 1.21-1.36) and number of different antipsychotics previously used (OR = 1.13, 95% CI 1.03-1.24) were significant predictors of relapse. The absence of cannabis consumption was a protective factor (OR = 0.72, 95% CI 0.58-0.89). Neither adherence to treatment in the previous 3 years nor type of antipsychotic regimen was significantly associated with relapse.

CONCLUSIONS

Number of previous hospitalizations and number of different types of antipsychotic drugs were associated with relapse. Absence of cannabis consumption was a protective factor.

The association between expressed emotion, illness severity and subjective burden of care in relatives of patients with schizophrenia. Findings from an Italian population

BACKGROUND

An appropriate understanding of the association between high-Expressed Emotion (EE) in family members of people with schizophrenia, patients' and relatives' correlates is needed to improve adaptation of psychoeducational interventions in diverse cultures. The aim of this study was to test the hypothesis that relatives designated as high EE would report higher subjective burden of care, and would be associated with objective variables that indicate greater illness severity i.e. number of previous hospitalizations and duration of illness.

METHODS

We performed secondary analyses of baseline data from a randomized controlled trial conducted in Italy.

RESULTS

High-EE relatives reported more subjective burden of care in disturbed behaviours and adverse effects areas, but did not perceive more deficits in social role performances. As regards illness severity characteristics, neither the number of previous hospital admissions nor the duration of illness was associated with high-EE. However, patients' previous psychosocial functioning, as measured by educational attainments, seems to protect the relative from high-EE status.

CONCLUSION

There is a need for cross-cultural comparisons of the subjective experience of distress and burden among high EE carers as a target for intervention, aimed at reducing family stress as much as improving patient outcomes.

Expressed emotion and caregiver burden in patients with schizophrenia

BACKGROUND

Family's expressed emotion has been shown to be predictive of outcome in mental and physical illnesses in a variety of cultural settings. The relationship between caregiver burden and high level of expressed emotions has demonstrated a high level of relapse among the psychiatric patients in the West.

AIM

The current study explores the relationship between caregivers' burden and level of expressed emotions by the patients with schizophrenia in Indian setting.

MATERIALS AND METHODS

The sample for the study consisted of totally 70 subjects comprising 35 schizophrenic patients and 35 caregivers. The schizophrenic patients who were attending the Day Care Center run by Department of Psychiatric and Neuro Rehabilitation Unit at National Institute of Mental Health and Neuro Sciences (NIMHANS) in Bangalore, India (a tertiary care center) and their primary caregivers were included. Family emotional involvement and criticism scale and The burden assessment schedule were administered to assess the expressed emotions and caregivers' burden. Carl Pearson Correlation test used to study the relationship between the variables.

RESULTS AND CONCLUSION

The study highlighted the need for addressing expressed emotion in comprehensive psychosocial intervention plan. More attention should be paid to the needs of the caregivers in order to alleviate their burden in managing mentally ill patients.

Adjunctive psychosocial therapies for the treatment of schizophrenia

Antipsychotic pharmacotherapy is the standard of care for the treatment of schizophrenia. Although pharmacotherapy effectively improves some symptoms, others can remain. Pharmacotherapy alone also tends to produce only limited improvement in social functioning and quality of life. Supportive psychosocial therapies have been used as adjuncts to pharmacotherapy to help alleviate residual symptoms and to improve social functioning and quality of life. Additionally, therapies with psychoeducational components can focus on improving medication adherence and reducing relapse and rehospitalization. This review describes the major psychosocial therapeutic strategies that have been used effectively in patients with schizophrenia (cognitive-behavioral therapy, family intervention, social skills, and cognitive remediation), with emphasis on their utility in improving medication adherence. Therapies that integrate various psychosocial therapeutic approaches are also discussed. It is concluded that psychosocial therapy is an effective adjunct to pharmacotherapy for schizophrenia. However, these therapies vary significantly in the functional domains that they address. It is therefore important to identify the form of psychosocial intervention most likely to benefit the individual patient, and to recognize that the effectiveness of any psychosocial intervention could be influenced by such factors as the presence and severity of psychotic or affective symptoms or cognitive impairment.

Trance, functional psychosis, and culture

This paper discusses the hypothesis that the symptoms of functional psychoses can be caused by culturally structured spontaneous trances that may be reactions to environmental stress and psychological trauma. Findings are reviewed of anthropological studies of meditative trance experiences in Indian yogis characterized by divided consciousness (dissociation), religious auditory and visual hallucinations, and beliefs in their own spiritual powers. An explanation of the psychological mechanisms of meditative trance is also provided, highlighting trance-related alteration of consciousness within an Indian cultural context. It is suggested that the psychological mechanisms of meditative trance are similar in structure to spontaneous trances underlying the symptoms of some functional psychoses. Findings from cross-cultural studies are also reviewed, highlighting the effects of culture on the symptoms, indigenous diagnoses, treatments, and outcomes of functional psychoses. In non-Western cultures, transient functional psychoses with complete recovery are 10 times more common than in Western cultures. It is suggested that egocentrism and a loss of spiritual explanations for psychosis in Western cultures constructs a clinical situation in which persons with functional psychoses are treated for a biogenetic (incurable) brain disease rather than a curable spiritual illness. This difference in cultural belief systems leads to poorer outcomes for Western patients compared to non-Western patients. Recognizing cultural differences in symptoms, indigenous diagnoses, and treatment for functional psychoses can help explain the dramatic cross-cultural differences in outcome.

Understanding successful community living by individuals with serious and persistent mental illness

34 volunteers diagnosed as chronically mentally ill were administered a questionnaire to evaluate what factors were important in preventing rehospitalization. The volunteers were divided into two groups based on their relapse history. Analysis showed the nonrelapse group were more likely to attribute factors such as in-home therapy, taking medication, and having fun with friends than did the group who had experienced at least one relapse in the past 24 months.

Quantitative and qualitative aspects of the social network in schizophrenic patients living in the community. Relationship to sociodemographic characteristics and clinical factors and subjective quality of life

Quantitative and qualitative aspects of the social network were investigated in a sample of 120 schizophrenic out-patients. Sociodemographic and clinical factors as well as subjective quality of life were investigated as to their relationship to the social network. The Interview Schedule for Social Integration (ISSI) was used to assess social network and Lancashire Quality of Life Profile was used to assess subjective quality of life. Psychopathology was measured by BPRS and psychosocial functioning by GAF. The patients reported a significantly worse social network compared to a normal sample both regarding quantitative and qualitative aspects of the network. Almost half of the patients wanted access to more social contacts. Relatives and friends turned out to be the patient's main source of supportive contacts. More severe negative and positive symptoms were related to a worse social network. Support was found for an association between characteristics of the social network, such as satisfaction with social contacts, and quality of life. The results give reason to suggest that the care system should consider the informal caregivers' situation and focus on interventions, which enhance the patient's satisfaction with social contacts.

Megavitamin and dietary treatment in schizophrenia: a randomised, controlled trial

OBJECTIVE

The aim of this study was to assess the efficacy of adjunctive megavitamin and dietary treatment in schizophrenia.

METHOD

A random allocation double-blind, controlled comparison of dietary supplement and megavitamin treatment, and an alternative procedure was given for 5 months to 19 outpatients with a diagnosis of schizophrenia. In addition to usual follow-up, the experimental group received amounts of megavitamins based on their individual serum vitamin levels plus dietary restriction based on Radioallergosorbent (RAST) tests. The control group received 25 mg vitamin C and were prescribed substances considered allergenic from the RAST test.

RESULTS

Five months of treatment showed marked differences in serum levels of vitamins but no consistent self-reported symptomatic or behavioural differences between groups.

CONCLUSIONS

This study does not provide evidence supporting a positive relationship between regulation of levels of serum vitamins and clinical outcome in schizophrenia over 5 months.

Critical comments made to schizophrenic patients by their families in Japan

Critical comments (CCs) are one of the components of expressed emotion (EE), an excess of which is related to relapse. Therefore, CCs could be a target of family psychoeducation. We examined the nature of CCs for clues to family therapy. We classified CCs expressed in the Camberwell Family Interview (CFI) into nine categories: (1) positive symptoms, (2) negative symptoms, (3) compliance with medical care, (4) life problems, (5) socially inappropriate behavior, (6) aggression, (7) rejection, (8) premorbid personality, and (9) other. Positive symptoms were the most frequently commented on (34%). Negative symptoms were not so frequently commented on (11%), as expected. In comparing high-EE and low-EE relatives or relapsers and nonrelapsers, there were no significant differences in the distribution of the nine CC categories. We conclude that positive symptoms should be a main topic of family psychoeducation in such cases.

Criticism and hostility in relatives of patients with schizophrenia or related psychoses: demographic and clinical predictors

Relatives' criticism and hostility are important risk factors for relapse in schizophrenia. In order to explain these attitudes, we examined a Norwegian sample of 47 recently hospitalized patients (with schizophrenia or related psychoses) and 72 relatives. Relatives' expressed emotion was assessed by means of the Camberwell Family Interview. Demographic and clinical data were used as predictor variables in confirmatory regression analyses. The most robust predictors of high levels of criticism were, on the part of the patient, lack of paid employment, more than 3 previous hospital admissions, more troublesome behaviours reported by relatives, especially anxiety/depression, and better cognitive functioning at admission. Robust predictors of hostility were lack of employment and more than 3 previous hospitalizations. Interventions to reduce criticism should include employing patients and working with relatives' unrealistic expectations.

Expressed emotion and the course of schizophrenia in Japan

BACKGROUND

We examined whether expressed emotion (EE) influenced the course of schizophrenia in Japan.

METHOD

We conducted a cohort study. Of 73 subjects with schizophrenia meeting the diagnostic criteria of ICD-9 or DSM-III-R, 52 participated in the study. The Camberwell Family Interview was conducted to evaluate EE. The subjects had been followed up for nine months and psychiatrists who were blind to the EE status evaluated their symptoms with the Brief Psychiatric Rating Scale.

RESULTS

The relapse rate in the high-EE group was 58% and that in the low-EE group 21% (P < 0.01). Nine-month relapse risk ratio was 2.72 (95% CI 1.24 to 5.97). CONCLUSION. In Japan, as elsewhere, EE is a good predictor of schizophrenic relapse.

Counseling caregivers of relatives with schizophrenia: themes, interventions, and caveats

As part of a controlled study of the effectiveness of a counseling program for family caregivers of patients with schizophrenia, we conducted a comprehensive examination of the process. The particular foci were on themes that arose during sessions, principal therapeutic interventions offered, and caveats for counselors working in the field. The most striking finding was the diverse range of themes, covering personal, coping, family, and social aspects of the caregiving experience. This required a correspondingly broad array of interventions. The implications are clear: confining counseling for caregivers to such traditional dimensions as education or attempts to reduce emotional expressiveness denies them the opportunity to deal with other equally relevant concerns.

The use of the Expressed Emotion Index as a predictor of outcome in first admitted schizophrenic patients in a French speaking area of Switzerland

A 5 year prospective study of 44 first admission schizophrenic patients was conducted in Geneva, in order to evaluate the prognostic value of Expressed Emotion (EE). The predictive power of the EE index was tested on 3 variables of outcome: relapse rates, social adaptation and hospital stays. The EE index and the outcome measures tended to be associated. After the third year, patients living with high EE relatives were significantly more maladjusted and relapsed more than those living with low EE relatives. At intake, the patients presenting more premorbid features lived in high EE households. Our results show that initial measure of EE in a first episode cohort is predictive of outcome over a five-year period. This may not be causal, as it cannot be excluded that poorer premorbid functioning alone may result in poorer outcome, and may also elicit high EE in the relative.

Mental health nurses working purposefully with people with serious and enduring mental illness--an international perspective

There has been a world-wide refocus on people with serious and enduring mental health problems. This has provided major challenges for all those involved in mental health care, as the last two decades have produced radical changes in service delivery and a range of new interventions. Mental health nurses are playing a central role as community based clinical case managers and are beginning to use a range of psychosocial interventions. They are also revitalizing skills in the more traditional areas of medication management and residential care. In addition, there are growing problems of substance abuse and violence which needs to be addressed. Mental health nursing is responding in this new era by various training initiatives. However, these programmes need rapid expansion as mental health nurses will continue to play a key role in the services of the future and therefore need these new skills.

Relationship between family attitudes measured by the Semantic Differential and relapse in schizophrenia: a 2 year follow-up prospective study

A prospective study was carried out to investigate the relationship between family attitudes and relapse in a cohort of 80 schizophrenic patients followed up for 2 years. A significant relationship was found between attitudes as measured by means of a semantic differential during hospitalization and later relapse. Lack of treatment compliance, negative symptoms, unemployment and poor pre-morbid adjustment were also associated with relapse. In a multivariate analysis some of these variables changed their predictive power but the association between attitudes and relapse was maintained.

Stress reduction in the social environment of schizophrenic patients

Patients with schizophrenia are sensitive to short term social stressors in the form of life events, and the long term stress of living with high Expressed Emotion (EE) relatives. A number of family interventions have been evaluated in controlled trials. A comparison of successful and unsuccessful interventions indicates the optimal type of intervention for patients in high EE environments.

The clinical utility of expressed emotion in schizophrenia

The measure expressed emotion (EE) has been developed over the course of the last 35 years, but it is only over the last decade that there has been an explosion of interest in it. It taps attitudes and behaviour in those who care for people with a range of psychiatric and physical conditions. It has been the basis for successful studies of psychosocial intervention in schizophrenia. However, several questions remain to be answered concerning EE. This article summarizes the results of an aggregate analysis of 25 studies of EE, which appears to be a robust predictor of relapse, in a range of locations and cultures, and in both sexes. Medication and family atmosphere exert effects on relapse that are completely independent. High contact with high-EE relatives increases relapse rates still further, while if anything contact with low-EE relatives is protective. We describe what is known about the relationship of EE with the behaviour of patients and carers. It is now clear that staff members can exhibit the same range of behaviours as the relatives of sufferers. Finally, we set out the implications for the routine management of people with longstanding schizophrenia.

The predictive utility of expressed emotion in schizophrenia: an aggregate analysis

We analysed aggregate data from 25 studies linking Expressed Emotion (EE) and schizophrenia. We had access to original data sets from 17 studies, and used published data from the remainder. This provided us with 1346 cases from around the world. The association of EE with relapse was overwhelming, and was maintained whatever the geographical location. The predictive capacity of EE was virtually identical in men and women. While high contact with a high EE relative increased the risk of relapse, the opposite was true in low EE households. Medication and EE were independently related to relapse, and thus EE status has no bearing on the decision to prescribe. Our findings were confirmed using log-linear analysis.

Recent developments in expressed emotion and schizophrenia

Expressed emotion (EE) has substantial scientific support as a predictor of relapse of positive symptoms. The median relapse rate in a high-EE environment is 48%, compared with 21% in a low-EE environment. This effect does not seem to be due to confounding with other variables, but it is subject to limitations in its scope of application. EE probably determines relapse through its effect on emotions and symptom control. A stress-vulnerability model of relapse is advanced that incorporates biological factors as well as cycles of mutual influence between symptomatic behaviour, life events, and EE. Aversive types of behaviour in patients and their relatives are seen as understandable reactions to stress that are moderated by social perceptions and coping skills. Families have made positive achievements, including the provision of non-invasive support.

A Portuguese/Brazilian study of Expressed Emotion

Expressed Emotion is a measure of family interaction, widely used in studies around the world to predict relapse in severe psychiatric disorders. The instrument was originally developed in London. It depends on subtle vocal nuances emerging in the course of the Camberwell Family Interview (CFI). The extent to which these can be picked up in different languages and different cultures is an interesting question. This paper presents the results of a study of EE from Brazil. The two raters achieved good reliability with master tapes in English, and the CFI was then translated into Portuguese. The raters also showed good reliability in Portuguese. This is at least consistent with the idea that similar behaviours can be picked up in different languages and cultures. Twenty nine relatives of 24 patients with schizophrenia were interviewed using the CFI. It was predicted that high Expressed Emotion would be rare in Brazil, a developing country. In fact, 59% of relatives were rated as high EE. Unlike studies from fully industrialized nations this high level of high EE was largely due to over-involvement. Our findings suggest both contextual and cultural influences on the relative salience of the different components of EE, a theme worth pursuing.
