Familial expressed emotion: outcome and course of Israeli patients with schizophrenia

We investigated the validity of expressed emotion (EE) in Israel. The study sample consisted of 108 patients with schizophrenia and 15 with schizoaffective disorder, and their key relatives. EE was rated with the Five Minute Speech Sample (FMSS). Patient households were categorized by EE and its two components: criticism and emotional overinvolvement. Patients were rated with the Brief Psychiatric Rating Scale (BPRS) at admission, at discharge, and 6 months after discharge. Readmissions were determined over a 9-month period. High EE and particularly high criticism were significantly associated with poorer outcome (higher rate of and earlier readmissions, and higher BPRS score at followup) and worse illness course (higher annual number of prior psychiatric hospital admissions). Odds ratios between high EE and high criticism and readmission were 2.6 and 3.5, respectively. The strongest predictor of earlier readmission was the interaction of high criticism x poor compliance with medication. The results converge to further confirm the notion that familial EE is a valid crosscultural predictor of the clinical course of schizophrenia. Moreover, EE has predictive power in very chronic samples. Criticism appears to be the crucial EE component linked with short-term outcome. Treatment aimed at reducing high criticism is warranted. The FMSS appears to have predictive validity.     

Expressed emotion: relevance to rehospitalization in schizophrenia over 7 years

Expressed emotion (EE) is an established factor in short-term relapse in schizophrenia. However, data on its long-term predictive ability are scarce. We extended our short-term investigation over 7 years' followup. The study population consisted of 108 patients, 93 with schizophrenia and 15 with schizoaffective disorder. EE of the key relatives was rated with the Five Minute Speech Sample (FMSS). Patient households were categorized by EE and its two components: criticism (CR) and emotional overinvolvement (EOI). High CR was associated with earlier first and second readmissions (Breslow p = 0.002 and 0.04, respectively). High CR was associated with a higher rate of readmissions (p = 0.01) and a longer hospital stay (p = 0.02) compared with low CR. Both compliance with pharmacotherapy and the interaction of high-CR x poor compliance were additional contributors to time to first readmission. This study is the first to demonstrate the prolonged predictive validity of EE. Our results support the value of CR as a prognostic indicator of the course of schizophrenia. The FMSS appears to have predictive power in respect to psychiatric hospitalization. Therapies aimed at lowering high EE seem warranted as a long-term preventive approach.     

Reliability of the 5-min speech sample for assessing expressed emotion in Japanese patients

Expressed emotion (EE) has been shown in various countries to be a good predictor of the clinical course of a patient's mental illness. Because the traditional EE interview requires considerable time and effort, this study examined the reliability of a method called the five-minute speech sample (FMSS) for assessing EE. The samples of 65 subjects were rated by the FMSS-EE coding system, and the interrater reliability among four authorized raters was investigated. Of these 65 samples, 10 (15%) were rated as high-EE (high critical, 6%; high emotional over-involvement (EOI), 9%), and 19 (29%) were rated as borderline (b-)-high-EE (b-critical, 15%; b-EOI, 14%). The intraclass correlation coefficient (ICC) was 0.91 for the overall category, 0.74 for criticism, 0.85 for EOI, 0.63 for b-critical and 0.54 for b-EOI. The FMSS was shown to be reliable for the assessment of EE, even outside of Western countries. However, the lower agreement in the subcategories of EOI and b-critical has to be considered as a limitation of this brief method.     

Clarifying the diversity of first-episode psychosis: Neuropsychological correlates of clinical symptoms

The aetiology of relatives' criticism (CC), hostility (H), and emotional overinvolvement (EOI) towards patients with schizophrenia is not clear. We analysed data from a study about expressed emotion (EE) in relatives of patients with schizophrenia according to DSM-III-R, to explore evidence of a relationship between EE pattern and a stress response syndrome in the relatives. CC, H, and EOI in 58 relatives of 40 patients with schizophrenia were assessed with the Camberwell Family Interview (CFI) shortly after admission and 4.5 months after discharge. Each relative's stress response was assessed with the General Health Questionnaire (GHQ-30). Relatives with a consistently high or a shifting EOI level reported prolonged higher stress scores than relatives with consistently low EOI level. We found no association between CC, H, and prolonged higher stress scores. Our study suggests that EOI could be linked to a stress response syndrome, whereas this does not seem to be the case for CC and H. If confirmed in future studies, this finding indicates that different treatment approaches should be offered to families of psychotic patients depending on the pattern of CC and EOI.     

Assessing the reliability of the five minute speech sample against the Camberwell family interview in a chronic fatigue syndrome sample

PurposeThe current study aimed to examine the reliability of the Five Minute Speech Sample (FMSS) for assessing relative Expressed Emotion (EE) compared with the Camberwell Family Interview (CFI) in a sample of relatives of adult patients with Chronic Fatigue Syndrome (CFS).Method21 relatives were recruited and completed both assessments. The CFI was conducted first for all participants, with the FMSS conducted approximately one month later. Trained raters independently coded both EE measures; high levels of rating reliability were established for both measures. Comparisons were conducted for overall EE status, emotional over-involvement (EOI) and criticism.FindingsThe distribution of high and low-EE was equivalent across the two measures, with the FMSS correctly classifying EE is 71% of cases (n = 15). The correspondence between the FMSS and CFI ratings was found to be non-significant for all categorical variables. However, the number of critical comments made by relatives during the FMSS significantly correlated with the number of critical comments made during the CFI. The poorest correspondence between the measures was observed for the EOI dimension.ConclusionThe findings suggest that the FMSS may be a useful screening tool for identifying high-EE, particularly criticism, within a sample of relatives of patients with CFS. However, the two measures should not be assumed equivalent, and the CFI should be used where possible, particularly with respect to understanding EOI.     

High expressed emotion: Marker for a caring family?

"Expressed emotion" (EE) is considered a marker of dysfunctional family interaction in patients with schizophrenia. An alternative hypothesis, however, is that at least some of the different elements of EE really represent attempts on the part of carers to cope with and care for a relative with a psychiatric disorder. EE (criticism and emotional overinvolvement) was measured in relatives (n = 31) of patients with psychotic illness using the Five-Minute Speech Sample (FMSS). Level of EE was examined in relation to (1) patient-reported family involvement in care over the previous 2 years as indicated by medication monitoring, involvement in treatment decisions, and providing a substitute for institutional care; and (2) symptom severity and number of psychotic episodes. Presence of EE in the relative was strongly associated with the degree of family involvement in care (odds ratio [OR] over three levels: 3.2; 95% confidence interval [CI], 1.1 to 9.0). In addition, presence of high EE was associated with number of psychotic episodes in the previous 5 years in the proband (OR over 0, 1, or 2 episodes: 6.2; 95% CI, 1.2 to 31.9). The association with family involvement was confined to emotional overinvolvement (OR = 9.1; 95% CI, 2.0 to 42.2), whereas the association with previous psychotic episodes was confined to criticism (OR = 20.6; 95% CI, 2.8 to 149.3). Emotional overinvolvement may be a state marker for attempts on the part of relatives to be partners in the care for patients with psychotic illness. High level of criticism may be a trait marker in relatives associated with poor prognosis, but could also develop in reaction to a frequently relapsing illness.     

What predicts the course of expressed emotion in relatives of patients with schizophrenia or related psychoses?

The expressed emotion (EE) index may not be as stable as it was once believed to be. The aim of this study was to identify variables associated with spontaneous change from low to high and from high to low levels of EE and EE subscales – critical comments (CC), hostility (H), emotional overinvolvement (EOI). Using a longitudinal, prospective study design, of 59 relatives having at least weekly face-to-face contact with 40 patients with an acute episode or relapse into schizophrenia (DSM-III-R) were interviewed by means of the Camberwell Family Interview (CFI) at admission and at 4 1/2 months after discharge. The results showed that high-high or unstable levels of CC, H or EE were associated with the patient not working or studying prior to admission. Relatives with low-high and high-high EOI patterns had more weekly face-to-face contact with the patient prior to admission than relatives with a low-low EOI pattern. Patients whose relatives had low-high CC and EE patterns were less ill at admission than patients whose relatives had low-low patterns. Higher perceived family burden was associated with, at admission, an unstable pattern of CC, and at follow-up, high-high EOI or EE patterns rather than low-low patterns. Our study suggests that it is possible to identify which relatives will have a stable and which a changing EE level, allowing for more focused intervention. Accepted: 29 June 1998     

Schizophrenic patients' perceptions of stress, expressed emotion, and sensitivity to criticism

This study was designed to get an "insider's view" of expressed emotion (EE) from the perspective of schizophrenic patients. Thirty-two patient and "influential other" pairs participated in the study. Patients' perceptions of EE attitudes in influential others were examined to determine whether they corresponded with actual EE ratings. Patients also rated how "stressed" they felt when interacting with their influential others, and patients' general sensitivity to criticism (STC) was assessed. As predicted, patients' perceptions of critical attitudes were related to actual EE ratings of criticism, although patients' perceptions of emotional overinvolvement (EOI) were not related to EOI ratings. Patients reported feeling more stressed when interacting with high-EE influential others, supporting an "EE as stressor" hypothesis. Finally, patients' STC influenced the level of stress they reported.     

Family factors and the course of bipolar affective disorder

Measures of family attitudes (expressed emotion [EE]) and interactional behaviors (affective style [AS]), both of which have been found to predict relapse in schizophrenia, were obtained from key relatives of 23 hospitalized recently manic bipolar patients. Patients were then followed up for a period of nine months after hospital discharge and rated on measures of clinical course, social adjustment, and medication compliance. Levels of intrafamilial EE and AS were found to predict likelihood of patient relapse at follow-up, especially when used as conjoint predictors of patient outcome status. Levels of AS also predicted degree of social adjustment at follow-up. The predictive relationships observed were independent of patient medication compliance, treatment regimen, baseline symptoms, demographics, and illness history. Results suggest that the emotional atmosphere of the family during the postdischarge period may be an important predictor of the clinical course of bipolar disorder.     

Expressed emotion in the relatives of people with epileptic or nonepileptic seizures

PURPOSE: This study investigated Expressed Emotion (EE) in relatives of people with epileptic or nonepileptic seizures (NES). METHODS: In a cross-sectional study, we used the Five-Minute Speech Sample to explore EE in the key relative of people with epilepsy (n = 36) and those with NESs (n = 21), as well as levels of anxiety and depression and use of coping strategies. RESULTS: A significantly greater proportion of relatives of NES than epilepsy patients were rated as high EE. Hostility was evident in more high-EE epilepsy than high-EE NES relatives, whereas emotional overinvolvement and positive relationship ratings tended to be more common in high-EE NES relatives. High- and low-EE epilepsy relatives used problem-focused as opposed to emotion-focused coping strategies significantly more than half the time. High EE and seizure frequency were not associated. Age at onset of the disorder was higher in epilepsy patients with high- than with low-EE relatives. CONCLUSIONS: Irrespective of etiology, carers for people with seizure disorders may find it hard to adjust to the difficulties these disorders create. Interventions that encourage problem-solving, reappraisals of "loss" and education regarding the causes of some of the patients' behavioral and mood problems seem likely to be beneficial.     

Predictors of components of expressed emotion in major caregivers of Turkish patients with schizophrenia

Background Expressed emotion (EE) is a concept reflecting the emotional atmosphere of the home environment. Specific components of EE, namely criticism, hostility and emotional over-involvement, have been found to be important predictors of relapse for schizophrenic patients. The main aim of this study was to examine the predictive power of patient and caregiver characteristics and caregivers' perceptions of frequency, coping, distress/discomfort, control of symptom behaviours by the patient, and attributions on locus of causality for the development of the illness on two components of EE (criticism/hostility and emotional over-involvement) in a sample of major caregivers of Turkish schizophrenic patients. Methods Seventy-two caregivers of schizophrenic patients were administered a set of questionnaires tapping socio-demographic and illness-related variables, the family questionnaire tapping perceived frequency, distress/discomfort, coping and control of symptom behaviours, causal attributions for illness and, finally, the Expressed Emotion Scale in the hospital setting. Results The results showed that caregivers' perceptions of coping with specific symptom behaviours decreased criticism/hostility (C/H), whereas perceptions of higher frequency of symptom behaviours increased C/H. For emotional over-involvement (EOI), the number of individuals living in the household, being the mother, father or the spouse, perceptions of coping with symptom behaviours and reported distress/discomfort about symptom behaviours were significant predictors. Conclusions Caregivers' perceptions of their ability to cope with symptom behaviours and their reported distress due to these behaviours are important variables related to components of EE and need to be targets in intervention studies. The cultural and clinical implications of the results for the management of schizophrenia and for support for the caregivers are discussed. Accepted: 26 September 2001     

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.     

Expressed emotion, types of behavioural control and controllability attributions in relatives of people with recent-onset psychosis

Purpose

High expressed emotion (high-EE), as compared with low-EE, relatives of patients with long-term psychosis may behave in a more controlling manner towards patients. Furthermore, higher levels of behavioural control have been associated with higher relapse rates. We investigated in a recent-onset sample, the extent to which high-EE relatives engage in controlling behaviours and attribute the patient’s illness to factors within patient’s control. Furthermore, we examined whether criticism/hostility and emotional overinvolvement (EOI) were, respectively, associated with two types of behavioural control (termed ‘direct influencing’ and ‘buffering’). We also investigated if controlling behaviours or attributions were better relapse predictors than EE.

Method

Measures of EE, controllability attributions and behavioural control and its subtypes (‘direct influencing’ and ‘buffering’) were derived from Camberwell Family Interviews with 80 relatives of recent-onset psychosis patients. ‘Direct influencing’ attempts denote any behaviour intending to coerce the patient; while ‘buffering’ attempts refer to any behaviour aiming to take control or do things for the patient.

Results

High-EE relatives perceived patients as having more control over their illness and were more inclined to attempt to control patients’ behaviour than low-EE relatives. Furthermore, high-EE-critical relatives used more direct influencing attempts, and high-EE–EOI relatives used more buffering attempts, but behavioural control was not associated with relapse in this recent-onset sample.

Conclusions

These findings may help us to understand the development of EE in recent-onset psychosis families. Acknowledging and integrating relatives’ attributional and behavioural patterns in designing and delivering clinical and familial early interventions should prove beneficial in meeting the needs of this specific population.     

Expressed emotion in first-episode schizophrenia and in ultra high-risk patients: results from the Programma2000 (Milan, Italy)

Expressed emotion (EE) was examined in a large sample of families of patients with either first-episode psychosis (FEP) within the schizophrenia spectrum, or who met the criteria for ultra high-risk (UHR) of psychosis. The aim of our study was to determine the patterns and relationship of EE with the duration of untreated illness (DUI) or of untreated psychosis (DUP), as well as with illness severity. The sample used in our study included 77 FEP and 66 UHR families. The Camberwell Family Interview was used to assess EE.In both samples, about one-third of patients’ families were classified as high EE, with emotional over-involvement (EOI) being the most frequent reason for a family to be classified as high EE. In FEP, higher EE correlated with longer DUI, and higher paternal EOI with longer DUP. DUI, however, was not found to correlate to EE in UHR patients. Severity of illness at the initial assessment did not relate to EE in either FEP or UHR families. Families of FEP and UHR patients were not found to differ in terms of the prevalence of a high EE rating, or of any of its subcomponents.The results of this study only partially support the hypothesis that high EE develops as a reaction to patient status. Patients from families with high EE could possibly benefit from interventions that are targeted at improving their resilience when dealing with problematic family environments.     

Symptoms and social adjustment of schizophrenic patients as evaluated by family members

The purpose of this study is to reveal the relationship between family expressed emotion (EE) and family evaluation for symptoms and social adjustment of schizophrenic patients. Chronic schizophrenic outpatients in offshore islands under stationary therapeutic conditions were studied. For evaluation, the Five Minute Speech Sample (FMSS) for EE and the Katz Adjustment Scale (KAS) for family evaluation of patients were used. EE level was high among relatives who thought the patient was belligerent, negativistic, unstable or helpless. High-EE relatives tended to evaluate their patients' performance of social activities rather low and showed strong dissatisfaction with the patient's leisure activities. Moreover, a high emotional overinvolvement (EOI) value is more common in Japan than in other countries. A subgroup of the FMSS-EOI, the emotional display, was seen where many mothers began to cry while speaking.     

Acculturation and expressed emotion in Caucasian, Latino, and black relatives of patients with schizophrenia

High expressed emotion (high EE) in family members (high levels of criticism, emotional overinvolvement, and/or hostility) has been found to be predictive of a poorer course of illness for patients with schizophrenia in many different cultures. Acculturation has also been found to relate to symptom severity and clinical course in a number of disorders (e.g., substance abuse, schizophrenia). There is reason to believe that acculturation may interact with EE, however, this relationship has yet to be examined systematically. The present study evaluated the relationship between acculturation and EE in a sample of 57 Caucasian, Latino, and black caregivers of patients with schizophrenia. Drawing from earlier research, it was hypothesized that more acculturated Caucasian and Latino relatives and less acculturated black relatives would be designated as high EE. Hypotheses were partially supported as results demonstrated that greater acculturation was associated with high EE for Latinos and low EE for blacks.     

Expressed emotion in the families of patients with schizophrenia and its influence on the course of illness

This paper presents the results of a study carried on an urban population in Belgrade investigating the connections between relapse in schizophrenia and the expressed emotion (EE) status of families where at least one of the patient's parents was a member of the household. The overall rate of high EE was just under 50%, in the middle of the range of values reported in studies carried out elsewhere. Relapse was found to be 10 times more frequent in patients whose families were rated high in EE. The sample consisted of 30 patients with hebephrenic schizophrenia and 30 with paranoid schizophrenia. The results suggested that these subtypes may be associated with different attributes of EE. Criticism was more frequent in families of patients with paranoid schizophrenia, while emotional overinvolvement was more frequent in families having a hebephrenic offspring. The different components of EE, suitably combined, may differentiate between the two subtypes of schizophrenia in terms of relapse rate. The relative odds for high criticism were similar for both subtypes, but for maternal overinvolvement (EOI) the odds were 10.5 for hebephrenic as against 2.3 for paranoid schizophrenia. Thus, EOI was more common in the families of those with hebephrenia and also led more frequently to relapse. There was also an inverse relationship between relapse rate and warmth, whether paternal or maternal. This was significant in both subtypes, and indicated that the threshold for the positive effeet of warmth was higher for fathers than for mothers. Marital conflict was significantly related to relapse, mainly because it was associated with high EE. Within the high EE group marital conflict did not predict relapse, whereas it was predictive in the low EE group. This implies that it was a source of some stress, but the effect was minor in comparison with that of high EE, emerging only in a low EE environment. Patient aggression showed only a non-significant trent towards association with relapse and with EE.     

The course of parental expressed emotion and psychotic episodes after family intervention in recent-onset schizophrenia. A longitudinal study

The stability of parental expressed emotion (EE) is analysed over about 9 years, and related to course of illness in patients with recent-onset schizophrenia. Families, who participated in a 15-month intervention, were randomised over two intervention conditions. Psychotic episodes were measured over 5 years after discharge. The Five Minute Speech Sample (FMSS) EE was elicited two times during the 12-month outpatient intervention and two times over 8 years after discharge on average. EE is expressed as criticism/dissatisfaction (CRIT), emotional overinvolvement (EOI), and as the classical dichotomous index. EE is not stable over the years. Intervention condition had no differential effect on EE as measured with CRIT and the dichotomous index. For EOI, an interaction between intervention condition and time was found. EE as assessed during intervention does not predict psychotic episodes during follow-up. An association was found between psychotic episodes and CRIT as assessed at 34 months after discharge. Family intervention may inhibit the development of high EOI for a limited period. Our results may be in support of the hypothesis that psychotic episodes in patients can affect the critical attitude in parents.     

Emotional over-involvement can be deleterious for caregivers’ health

The study of emotional over-involvement (EOI) has focused primarily on its relationship with patients’ course of illness. We know little about the predictors and possible consequences of EOI for caregivers. Based on past research, we tested the hypotheses that EOI is associated with worse physical and psychological health among caregivers and examined whether caregiver burden and social support may mediate this relationship. Method In a sample of 37 Mexican American caregivers and their ill relatives recruited from two outpatient clinics, we examined the relationships between EOI, caregiver burden, caregivers’ level of social support, and caregivers’ health. Additionally, we examined whether caregiver burden and social support may mediate the relationship between EOI and caregivers’ health. Cross-sectional analysis indicates that at baseline EOI was not associated with caregiver burden or social support, but was related to worse current health. Longitudinal analysis, however, indicates that EOI at baseline was associated with greater burden, less instrumental support, and worse health among caregivers at follow-up. Moreover, objective burden and instrumental support mediated the relationship between EOI and several health outcomes. Consequently, EOI may be a marker of poor current health status and predicts worse future health among Mexican–American caregiving relatives of individuals with schizophrenia. Moreover, changes in burden and social support associated with EOI appear to mediate the relationship between EOI and several health outcomes among caregivers. These findings suggest that it might be important for family interventions to not only address the functioning of individuals with schizophrenia but also their caregiving relatives.
