Expressed emotion and the course of schizophrenia in Iran

Caregivers' experiences and perspectives of factors associated with relapse in Iranian people living with schizophrenia: A qualitative study

BACKGROUND

Relapse in People Living with Schizophrenia (PLS) has several reasons and recognizing these can increase the effectiveness of treatment interventions. Formal and informal caregivers are an informed source to reduce relapse in PLS.

AIM

This study explores the caregivers' perspective in Iran on the factors affecting relapse in PLS.

METHOD

A total of 28 caregivers (16 formal caregivers and 12 informal caregivers) of PLS were enrolled in our qualitative study. A content analysis was conducted using individual and group, semi-structured in-depth interviews with informal and formal caregivers of PLS. This study was conducted in a hospital, three universities, and a non-governmental organization in Tehran, Iran.

RESULTS

The majority (69%) of the participants were females. About half of the informal caregivers were over 60 years old and about 40% of the formal caregivers were in the age range of 30 to 40 years. The average number of years of work for informal caregivers was 17.6 years and the average of work experience among the formal caregivers was 14.1 years. Seven key dual themes were identified from data: 'awareness-stigma', 'social support-social exclusion', 'treatment adherence-treatment discontinuation', 'holistic approach - one-dimensional approach', 'supported employment-social dysfunction', 'emotional management in family - family with high emotional expression', and 'access to treatment-treatment gap'.

CONCLUSION

The results of this research can help practitioners and policymakers to enable evidence-based practices to reduce relapse in PLS by emphasizing and acting on factors identified in our analyses.

Evaluating family knowledge about sexual health in patients with severe mental illness: a qualitative study in Iran

INTRODUCTION

Although paying more attention to sex education in patients with severe mental illness is recommended in the literature, the role of families has not been specifically clarified.  AIM: This study aims to explore family knowledge about sexual health in patients with severe mental illness in Iran.

METHODS

We conducted a total number of 21 interviews with 4 patients, 5 families, 7 psychiatrists, 1 general practitioner, 2 nurses, and 2 psychologists through purposive sampling. The text was analyzed using conventional qualitative content analysis.

RESULTS

The family knowledge about patients' sexual health is described in three subcategories: 'informal sources for knowledge acquisition', 'common myths, and 'inappropriate reaction to the patients' needs".

CONCLUSIONS

Family sex education should be integrated into a comprehensive rehabilitation program to promote sexual health in patients with severe mental illness. Family members should be aware of the necessity of accurate information about patients' sexual concerns.

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.

Burden experienced by caregivers of schizophrenia patients and its related factors

Background: Deinstitutionalization of patients with schizophrenia shifted the primary locus of care from psychiatric hospitals to family and informal caregivers. Family members often play a vital role as caregivers in the lives of individuals with schizophrenia and other serious mental illnesses. This study aimed to assess the burden experienced by the caregivers of patients with schizophrenia and to evaluate its correlation with some demographic characteristics of patients, their caregivers, and the level of expressed emotion in the family.

Methods: This descriptive-analytic study was conducted on 172 schizophrenic patients and their primary caregivers, selected from the outpatient department of a psychiatric hospital in Tehran, Iran, using convenience sampling. Caregivers were evaluated with Zarit Burden Interview and Family Questionnaire to assess the burden experienced by the caregivers and the level of expressed emotion in the family, respectively. Data were analyzed using Spearman correlation coefficient and linear regression method. Data were analyzed using SPSS software (Version 21) and significance level was set at p< 0.05.

Results: The level of burden experienced by most of primary caregivers was higher than moderate. The scores obtained in the subscales of emotional over involvement and critical comments were higher than the cutoff point in 51.7% and 64.5% of caregivers, respectively, and the scores had a significant direct correlation with the burden experienced by the caregivers. The findings of multiple linear regression showed that lower family income (β= -0.33, p< 0.001), higher duration of disorder (β= 0.19, p= 0.006), and younger age at onset of the disorder (β= -0.26, p= 0.001) were predictive of higher burden of disease on caregivers.

Conclusion: Based on the results, some demographic factors of the primary caregivers, patients, and their family significantly affected the burden experienced by the primary caregivers. Most of the caregivers had high expressed emotions and a significant direct association existed between the expressed emotions and the burden experienced.

Caregiving processes and expressed emotion in psychosis, a cross-cultural, meta-analytic review

The construct of Expressed Emotion (EE) is a reliable predictor of relapse in psychotic disorders globally. However, cultural differences in the level and manifestation of EE have been reported. This review was conducted in line with PRISMA guidelines to demonstrate the distribution of EE and its domains cross-culturally as well as its relationship with relapse in psychosis. Ninety-six studies reported global EE scores and/or separate EE domains amongst caregivers of a family member with psychosis and used the Camberwell Family Interview (CFI) to measure EE. In the meta-analysis (k = 34, n = 1982), exposure to high EE was indicative of a 95% increased likelihood of relapse compared to low EE. However, no significant effect of geographical region on global EE scores (high/low) or EE domains was found. Several adjustments to the scoring of the CFI were highlighted based on cultural norms, particularly relevant to the domains of emotional over-involvement, warmth and criticism. Although this made meaningful quantitative comparisons across studies difficult, it nonetheless highlighted cultural considerations that need to be taken into account when interpreting EE and understanding its relationship to clinical outcomes. There is not a universal normative EE experience, with cultural variation in the scoring and interpretation of EE existing as evidenced by adjusted cut off scores and conceptualisation of EE constructs. Thus, it is important for clinical practitioners to have an awareness of different cultural norms in relation to caregiving and care receiving behaviours, which can inform adaptations to clinical interventions in multicultural settings.

Expressed emotion and the course of schizophrenia in Pakistan

PURPOSE

Aim of the study is to evaluate the predictive power of Expressed Emotion in Schizophrenia relapse in Pakistan.

METHOD

A longitudinal study was conducted comprising 53 in-patients' sample diagnosed with Schizophrenia and their 101 key carers. Participants fulfilled DSM-IV-TR criteria for Schizophrenia based on Structural Clinical Interview for the DSM-IV diagnosis. Symptomatic status was measured through Brief Psychiatric Rating Scales-Expanded (BPRS-E). Caregivers' level of EE was assessed through Camberwell Family Interview (CFI). Patients were followed up for 9 months after hospital discharge.

RESULTS

Relapse rate for patients with high-EE household was 72% as compared with 36% in the low-EE household. Logistic Regression showed a positive relationship between high-EE and relapse (CI 0.06-0.80; p < 0.05). Both hostility and critical comments emerged as significant predictors of relapse. The odds ratio showed that a one unit increase in caregivers' score on the CCs and hostility scales were associated with a 1.29 (CI 1.06-1.56; p < 0.05) and 1.89 (CI 1.14-3.13; p < 0.05) times increased rate of relapse, respectively. Conversely, a non-significant relationship was observed between EOI and relapse.

CONCLUSIONS

The findings from this study confirmed the validity of EE construct in predicting schizophrenia relapse in a Pakistani sample. However, medication compliance has not been experimentally controlled and that is one of the limitations of the study.

Schizophrenia relapse in Kuala Lumpur, Malaysia: do relatives' expressed emotion and personality traits matter?

BACKGROUND

Schizophrenia which is perhaps the most disabling and puzzling form of a mental disorder is often conceptualized as 'gila' (lunacy or madness) by the Malaysian society. The debilitating nature of the disorder and recurrent relapse of its psychotic episodes have often been misunderstood and lead to confusion among the family members, who play the role as primary caregivers. While expressed emotion (EE) has been widely studied in the Western world, it is not well understood in Malaysia.

OBJECTIVES

This study aimed at investigating the predictive role of relatives' EE index and components as well as personality traits in relapse among schizophrenia patients in Kuala Lumpur and Klang Valley, Malaysia.

METHODS

A total of 160 subjects consisting of 80 patients diagnosed with chronic schizophrenia and 80 relatives were recruited to participate in Phase 1 of the study. Only patient-participants were followed-up 6 months later for Phase 2 of the study in order to check for possible relapse. The Family Questionnaire (FQ) and the short scale Eysenck Personality Questionnaire-Revised (EPQ-R) were administered to measure relatives' EE and personality traits, respectively. Patients' were considered to relapse if they were readmitted into psychiatric wards 6 months post-hospital discharge.

RESULTS

The findings revealed that the odds for patients to relapse were increased by 8 times when relatives demonstrated high-EE level. Relatives' critical comments (CC) turned out to be the strongest predictor with the odds to relapse increased by 12% when they demonstrated an increase in CC level. Relatives' personality traits particularly the extraversion trait also turned out to be the significant direct predictor to patients' relapse. Our results showed that a unit decrease in extraversion trait score predicted the odds for patients to relapse by 23%.

DISCUSSIONS

Our findings supported the Western findings on the significant role of relatives' high-EE level particularly the CC scale on the course of schizophrenia. The novelty of the current finding was demonstrated in the significant role of relatives' extraversion trait that directly predicted patients' relapse. Results also indicated the feasibility of EE in predicting relapse among schizophrenia patients in Klang Valley, Malaysia.

Definitions and drivers of relapse in patients with schizophrenia: a systematic literature review

Relapse in patients with schizophrenia has devastating repercussions, including worsening symptoms, impaired functioning, cognitive deterioration and reduced quality of life. This progressive decline exacerbates the burden of illness on patients and their families. Relapse prevention is identified as a key therapeutic aim; however, the absence of widely accepted relapse definition criteria considerably hampers achieving this goal. We conducted a literature review in order to investigate the reporting of relapses and the validity of hospitalization as a proxy for relapse in patients with schizophrenia. The primary aim was to assess the range and validity of methods used to define relapse in observational or naturalistic settings. The secondary aim was to capture information on factors that predicted or influenced the risk of relapse. A structured search of the PubMed database identified articles that discussed relapse, and hospitalization as a proxy of relapse, in patients with schizophrenia. National and international guidelines were also reviewed. Of the 150 publications and guidelines identified, 87 defined relapse and 62% of these discussed hospitalization. Where hospitalization was discussed, this was as a proxy for, or a component of, relapse in the majority of cases. However, hospitalization duration and type varied and were not always well defined. Scales were used to define relapse in 53 instances; 10 different scales were used and multiple scales often appeared within the same definition. There were 95 references to factors that may drive relapse, including non-adherence to antipsychotic medication (21/95), stress/depression (11/95) and substance abuse (9/95). Twenty-five publications discussed the potential of antipsychotic therapy to reduce relapse rates-continuous antipsychotic therapy was associated with reduced frequency and duration of hospitalization. Non-pharmacological interventions, such as psychoeducation and cognitive behavioural therapy, were also commonly reported as factors that may reduce relapse. In conclusion, this review identified numerous factors used to define relapse. Hospitalization was the factor most frequently used and represents a useful proxy for relapse when reporting in a naturalistic setting. Several factors were reported to increase the risk of relapse, and observation of these may aid the identification of at-risk patients.

Family expressed emotion in a Javanese cultural context

This study aims at understanding the emotional milieu of families of psychotic patients, focusing on the concept of expressed emotion (EE). A combination of ethnographic and clinical methodology was employed. During the fieldwork in Yogyakarta, Indonesia, nine participants diagnosed as having first episode psychosis and their families were followed closely over the course of 1 year in their natural home setting. Through ongoing engagement with families, the researcher was able to gather data on the diversity of family responses to illness. Despite the fact that most families in this research could be considered to have low EE, ethnographic observation provided a more complex and nuanced picture of family relationships. This article discusses four issues concerning EE in relation to Javanese culture: the role of interpretation, the coexistence of criticism and warmth, the interpretation of boundary transgression, and the cultural concept of warmth and positive remark.

Relationship of family caregiver burden with quality of care and psychopathology in a sample of Arab subjects with schizophrenia

BACKGROUND

Although the burden experienced by families of people with schizophrenia has long been recognized as one of the most important consequences of the disorder, there are no reports from the Arab world. Following the example of the five-nation European (EPSILON) study, we explored the following research question: How does the relationship between domains of caregiving (as in the Involvement Evaluation Questionnaire--IEQ-EU) and caregiver psychic distress on the one hand, and caregiver's/patient's socio-demographics, clinical features and indices of quality of care, on the other hand, compare with the pattern in the literature?

METHOD

Consecutive family caregivers of outpatients with schizophrenia were interviewed with the IEQ-EU. Patients were interviewed with measures of needs for care, service satisfaction, quality of life (QOL) and psychopathology.

RESULTS

There were 121 caregivers (66.1% men, aged 39.8). The IEQ domain scores (total: 46.9; tension: 13.4; supervision: 7.9; worrying: 12.9; and urging: 16.4) were in the middle of the range for the EU data. In regression analyses, higher burden subscale scores were variously associated with caregiver lower level of education, patient's female gender and younger age, as well as patient's lower subjective QOL and needs for hospital care, and not involving the patient in outdoor activities. Disruptive behavior was the greatest determinant of global rating of burden.

CONCLUSION

Our results indicate that, despite differences in service set-up and culture, the IEQ-EU can be used in Kuwait as it has been used in the western world, to describe the pattern of scores on the dimensions of caregiving. Differences with the international data reflect peculiarities of culture and type of service. Despite generous national social welfare provisions, experience of burden was the norm and was significantly associated with patient's disruptive behavior. The results underscore the need for provision of community-based programs and continued intervention with the families in order to improve the quality of care.

Family and patient predictors of symptomatic status in schizophrenia

OBJECTIVE

To test an interactive hypothesis that, in schizophrenia, a combination of patients' and relatives' characteristics at 1-month postdischarge from hospital (Time 1 [T1]) better predicts the level of psychotic symptoms at follow-up (Time 2 [T2]), than do the characteristics of patients or relatives alone.

METHODS

Male patients (n = 38) with a diagnosis of schizophrenia, without substance abuse, and in contact with their families, were recruited at the time of hospital discharge. Patients' psychotic symptom levels were monitored every 2 weeks until follow-up, while family measures were administered at T1 and T2. The 4 predictor variables in the regression analysis were T1 symptom levels of the patient and 3 measures of family interaction (expressed emotion, family burden, and family functioning).

RESULTS

The model based on the family variable, family burden at T1, and the patient variable, patients' remitted levels of psychotic symptoms at T1, was found to significantly predict the level of psychotic symptoms at T2. These 2 T1 variables made independent and additive contributions to the level of psychotic symptoms at T2, predicting 19% of the variance. Neither expressed emotion nor family functioning at T1 added to the prediction.

CONCLUSION

This finding suggests a patient-family interactional component to symptomatic relapse in schizophrenia.

Expressed emotion and relapse of psychopathology

Expressed emotion (EE) is a measure of the family environment that predicts worse clinical outcomes for patients with a range of disorders. This article describes the assessment of EE and the evidence linking EE to clinical relapse in patients with psychopathology. This is followed by consideration of the possible explanatory models that might account for the EE-relapse link and a review of the evidence suggesting that EE may play a causal role in the relapse process. The results of studies describing the effect of EE on patients, as well as cross-cultural aspects of the construct, are highlighted. Finally, the possibility that high levels of EE may stress patients by perturbing activity in neural circuits that underlie psychopathology is considered and new directions for EE research are outlined.

Expressed emotion in relatives of first-episode and chronic patients with schizophrenia and major depressive disorder-a comparison

Relatives of first-episode and chronic schizophrenic and depressed patients were examined with respect to their expressed emotion (EE) status. The two aims of the study were to (1) investigate whether relatives of first-episode patients differed from family members of chronic patients, and (2) whether EE indices of relatives of schizophrenic patients were comparable to those of depressed subjects. Twenty patients of each diagnostic group (DSM-III-R and DSM-IV) were included, i.e. a total of 80 patients. The EE status of key relatives was assessed with the Five-Minute Speech Sample on the basis of critical comments and emotional overinvolvement. Additionally, the new criterion 'covert criticism' was applied to detect indirect expressions of critique. Relatives of first-episode and chronic patients of both diagnostic groups did not differ significantly regarding their EE status; in first-episode patients, 52.5% of relatives were classified high EE; in chronic patients, 45%. Moreover, EE indices of relatives of schizophrenic and depressed patients were comparable. Analysis revealed 52.5 and 45% high-EE relatives in the depression and the schizophrenia subsamples, respectively. Thus, the overall incidence of high-EE relatives was comparable to numbers reported in the literature. In our study EE status of relatives was not disease-specific, and it was independent of chronicity of illness.
