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

The relationship between expressed emotion, personality traits and prognosis of alcohol and substance addiction: 6-month follow-up study

AIM

Preventing relapses in addiction and related factors are still being investigated. There is inadequate data, specifically, on the effects of expressed emotion (EE) among key relatives of patients with alcohol and substance use disorder (ASUD), the personality traits of patients, and the clinical features of addiction on relapses.

MATERIAL AND METHOD

This study was conducted with patients with ASUD (n = 102, 98 male) and their relatives (n = 102, 44 male). The Dependency Profile Index, and the Temperament and Character Inventory were applied to the patients, while the EE scale was applied to key relatives. Relapse rates were evaluated six months later.

RESULTS

EE levels among key relatives of patients were found to be associated with early relapse rates (p = 0.002). In addition, the individuals the patients lived with (p = 0.041), income level (p = 0.048), working status (p = 0.039), time spent in profession (p = 0.007), and severity of addiction (p = 0.016) were all found to be significantly associated with relapses. The personality traits of patients were not related to early relapses. In logistic regression analysis, EE and time spent in a profession were found to be significantly associated with relapses (p = 0.014, 0.043 respectively), while other variables were not significant.

CONCLUSION

The relationship between relapse in the early period of abstaining from substance use and EE levels of key relatives seems to be a greater determinant for ongoing success than several other variables in patients with ASUD, including addiction severity. The research suggests that families be involved in programs that help prevent relapses.

Expressed emotion as an adaptation to loss

Background

The factors influencing the development of expressed emotion (EE) are still unclear. Understanding the carer and patient appraisals operating during the initial adaptation to psychosis may help to clarify the early ontogenesis of EE.

Method

Fifty patients and key carers were followed-up over 9 months and their appraisals of loss and burden were measured in relation to the evolution of high emotional overinvolvement (EOI) and critical (CC) relationships.

Results

The appraisal of loss was linked to high EOI but not high CC relationships at baseline. Loss reduced by 9-month follow-up in those changing from high EOI to high CC or low EE. Subjective burden of carers was linked to loss but not to EE status. Patients' and relatives' appraisals of loss were strongly correlated, particularly in high EOI relationships. Longer duration of untreated psychosis was associated with high CC.

Conclusions

The results are consistent with Bowlby's attachment theory, where EOI and coercive criticism maybe understood as adaptive reactions to perceived loss. Implications for family intervention in first-episode psychosis and the prevention of high EE are discussed.

Do stress and support matter for caring? The role of perceived stress and social support on expressed emotion of carers of persons with first episode psychosis

BACKGROUND

Caring for a person with first episode psychosis (FEP) is a challenging and distressing task for the carers. The carers' stress in the early stage of psychosis can increase their expressed emotion (EE) while social support is hypothesized to decrease EE. However, the influence of stress and social support on carers' EE is not well understood in FEP.

AIM

To examine how the stress and social support shape expressed emotion in the carers of FEP.

METHODS

Seventy one carers of the patients with non-affective FEP were recruited from the inpatient psychiatry ward of a tertiary mental health care center in South India. The family questionnaire, perceived stress scale and multidimensional scale of perceived social support were used to measure their EE, stress and social support respectively.

RESULTS

Carers experienced high level of perceived stress, EE and poor social support. Perceived stress significantly increased EE (β=0.834; p<0.001) and social support did not significantly influence EE (β=-0.065; p>0.05). Perceived stress predicted 76 percent of the variance on EE (Adjusted R²=0.761).

CONCLUSION

The results emphasize high level of stress and EE in carers of patients with FEP that implies the need for appropriate psychosocial interventions to manage their stress.

Hostility toward Caregivers as a Selection Criterion for Transplantation

Researchers have focused on hostility and aggression of psychiatric patients but little is known about what effects transplant candidates' hostility toward their caregivers has on the care the candidates receive. Hostility is defined as any verbal, nonverbal, or physical behavior which threatens persons or property. Although hostility may be one of the precipitating factors in the need for an organ transplant, it may also be a response of the patient to his or her condition. This study focused on whether transplant coordinators felt that hostility should be used as a criterion for accepting or rejecting a transplant candidate. A nonexperimental descriptive survey design targeted 559 organ transplant coordinators who were members of the North American Transplant Coordinators Organization. Many coordinators in this study (62%) felt that a hostile candidate should not receive an organ transplant. Different methods of caring for hostile patients should be explored, especially for those who are antagonistic and who exhibit aggressive behaviors. Given the scarcity of donor organs, ethical principles must guide the allocation of these organs and the selection of transplant recipients.

Family burden in schizophrenia: the influence of age of onset and negative symptoms

Abstract Objectives: To investigate the determinants of family burden in a sample of patients with schizophrenia and their caregivers. Methods: Thirty-one stable patients with schizophrenia and their main caregivers were recruited. Sociodemographic variables were assessed in a semi-structured interview, and positive and negative symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Cognitive performance was assessed with the Schizophrenia Cognition Rating Scale (SCoRS). Levels of burden on caregivers were assessed with the Family Burden Interview Schedule (FBIS). Interactions among variables were analyzed using Pearson correlations and linear regression analysis. Results: Objective and subjective FBIS scores were 1.9 (standard deviation [SD] = 0.5) and 2.4 (SD = 0.6) respectively. Objective burden correlated positively with positive and negative symptoms, and cognitive impairment. Subjective burden correlated positively with positive symptoms and negatively with mean age of disease onset. Positive, negative and cognitive symptoms accounted for 47.6% of the variance of objective burden, with negative symptoms accounting independently for 30.3%. Age of onset, parents as caregivers and positive symptoms accounted for 28% of the variance of subjective burden, with age of onset independently explaining 20.3%. Conclusion: Patients' clinical and sociodemographic variables are important determinants of family burden in schizophrenia. Objective burden is predicted by symptoms, particularly negative ones. Subjective burden is predicted by symptoms and sociodemographic variables, particularly age of disease onset.

The relationships among perceived criticism, family contact, and consumer clinical and psychosocial functioning for African-American consumers with schizophrenia

This study examined whether Perceived Criticism (PC) was related to community functioning in a sample of African-American consumers with schizophrenia. The study tested assumptions from the Expressed Emotion literature that were based primarily on samples of white consumers. The study found that PC affected psychiatric symptomatology but not psychosocial functioning. Greater family contact was strongly related to better psychosocial functioning. Findings suggested that the nature and impact of contact between consumer and family for this sample of African-Americans appears different from what has been found in white, middle-class samples.

Patient perceptions of caregiver criticism in psychosis: links with patient and caregiver functioning

Expressed emotion (EE) has been described as a measure of caregivers' appraisals of the quality of their relationship with patients. However, far less is known about how the perception of their caregivers by patients with psychosis is shaped by caregivers' EE, and nothing about the clinical correlates of perceived EE. The current study examines the association of patient ratings of carer criticism with patient and carer characteristics. Patient ratings of carer criticism were also compared with the ratings of the carer derived from the Camberwell Family Interview. Sixty-seven patient-carer dyads participated in the cross-sectional study. Perceived carer criticism was associated with general psychopathology in patients, but not with overall levels of positive or negative symptoms of psychosis. Patients with lower levels of social functioning, higher levels of negative affect, and negative schematic beliefs about other people, tended to perceive greater criticism. Perceptions of carer criticism were associated with Camberwell Family Interview ratings of carer criticism, hostility, and high EE independently of affect, and poorer functioning. High EE was a significant predictor of perceived carer criticism. This study supports the validity of using feedback from patients to assess the emotional climate of the family environment.

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.

Burden of relatives and predictors of burden. Baseline results from the Munich 5-year-follow-up study on relatives of first hospitalized patients with schizophrenia or depression

In the present study, part of the Munich 5-year follow-up study on key relatives of first-hospitalized schizophrenic and depressive patients, baseline results with respect to relatives' burden and predictors of burden are presented. Basing on a transactional stress model the following hypothesis was tested: the impact of the patients' illness on their relatives' stress outcome is moderated by the psychosocial resources of the relatives. Stress outcome was measured in terms of objective and subjective burden, well-being, self-rated symptoms and global satisfaction with life. Potential moderating variables included age and gender, generalized stress response and illness-related coping strategies, beliefs of control,perceived social support,personality factors, expressed emotion and life stressors. A total of 83 relatives, whose ill family members had been hospitalized in the Department of Psychiatry of the Ludwig-Maximilians-University of Munich for the first time, participated in the study. Findings did not entirely support the hypothesis. On the one hand, relatives' stress outcome was independent of the objective stressors (severity of the illness, kind of symptoms, level of psychosocial functioning at admission). On the other hand, burden was significantly associated with several psychosocial resources and dispositions of the relatives. Multivariate linear regression analyses indicated that expressed emotion, emotion-focused coping strategies and generalized negative stress response are the most relevant predictors of burden. It is argued that a multidimensional approach in burden assessment is necessary and has relevant implications for improving family intervention strategies.

Do all people with schizophrenia receive the same benefit from different family intervention programs?

The study evaluated baseline characteristics that could be used to predict the outcome of family intervention in schizophrenia and focussed on identifying the subgroups of patients who were more likely to respond to one therapeutic modality than another. We conducted a controlled trial in which participants were assigned at random to either a Behavioral Family Intervention Group or a Relatives' Group. Patients in one catchment area, having suffered one psychotic relapse within the previous year and living with their families, were assessed by an independent evaluator at baseline and 12 months later. Some clinical and family factors such as the duration of illness, number of hospital admissions and relatives' level of psychological distress can predict the differential outcome of either type of family intervention modality. The results suggested that the short-term illness group requires more intensive and personal intervention, while the long-term illness group needs more continuous support. Our results should be confirmed in a larger sample before clinical recommendations can be made.

Relatives' distress and patients' symptoms and behaviours: a prospective study of patients with schizophrenia and their relatives

OBJECTIVE

The aim of this study is to explore the relationship between relatives' distress and patients' symptoms and behaviours.

METHOD

Fifty relatives in close contact with 36 patients with schizophrenia DSM-III-R filled in the General Health Questionnaire (GHQ) and the Perceived Family Burden Scale (PFBS) at the patient's hospital admission, 4.5 and 9 months post-discharge. The patients were assessed by means of the Positive and Negative Syndrome Scale (PANSS).

RESULTS

The PFBS anxiety-depression cluster was at all three assessments positively correlated with relative's distress (GHQ), not with PANSS anxiety and depression measurements. In multiple regression analysis PFBS, but not PANSS, was related to relatives' distress.

CONCLUSION

Relatives' distress was related to their reports of problematic patient behaviours, especially anxiety-depressive behaviour, not to symptoms as measured by clinical interviews. High distress is related to high expressed emotion, suggesting that relatives' report of patient's behaviour should be addressed to improve patient's outcome.
