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

Family environmental factors in at-risk mental states for psychosis

The family environment represents an important psychosocial factor that impacts psychosis prognosis, but little is known about its effect on the at-risk stages of psychosis. This study presents a comprehensive review and summarizes the state of the art of study on the wide range of family factors related to family functioning in the At-Risk Mental State (ARMS) for psychosis, as well as family interventions in ARMS individuals. Publications were retrieved by an extensive search on MEDLINE, PsycINFO and SCOPUS (1990-2020). Expressed Emotion is the most studied variable in ARMS literature, but there is scarce evidence of the role of other significant family factors at the ARMS stage. Overall, high Expressed Emotion did not appear to be reactive to ARMS patients' poor clinical status. However, initial evidence has suggested that relatives' beliefs about the disorder may play a significant role, either as mediators of these relationships or as predictors of Expressed Emotion. Available literature yet to yield a consistent pattern of findings on the association between Expressed Emotion or other family functioning indicators and negative outcomes, but some longitudinal studies highlight the greater potential for the protective effects of positive family environments at the ARMS stage. Family-based interventions have demonstrated benefits for both ARMS individuals and family dynamics. An increased focus on the impact of the at-risk stage of illness on relatives' mental well-being is required to provide family support based on their needs and to clarify the mechanisms leading to dysfunctional family dynamics during the critical ARMS period.

Caring for caregivers: Understanding and meeting their needs in coping with first episode psychosis

AIM

The first episode of psychosis is a challenging time for both patients and those who care for them. Although literature on treatment is plentiful, literature on how to best support caregivers is more scarce. This review was undertaken to better understand the caregiver experience, determine which interventions most effectively alleviate their burden and examine which other factors may affect outcomes.

METHODS

Articles were retrieved from PubMed and OVID using the following search terms: first episode psychosis (FEP), schizophrenia, caregiver, intervention and burden in various combinations. Only peer-reviewed articles germane to FEP caregiver experience and interventions written in English were included.

RESULTS

Caregivers can experience grief, guilt and anxiety during this time. While concerned for their loved one, their own lives take a back seat and their mental and physical health are adversely affected. Some are better prepared to cope and are typically warm, decisive, confident and optimistic. Their families are organized and flexible. Others are less prepared and are more likely to have poor self-esteem, use avoidant coping strategies and be overly critical. Their families are controlling and have difficulty with communication and balance. These caregivers stand to benefit most from interventions.

CONCLUSIONS

Effective interventions incorporate psychoeducation, problem solving strategies, peer support and clinician guidance. A higher level of interaction with facilitators and peers is associated with better results. Benefits include decreases in caregiver burden, depressive and anxious symptoms and feelings of shame and isolation. Although the literature has yet to isolate the key factors of a successful intervention, this review provides practical suggestions for clinicians and further illustrates the need for more research.

Predictors of criticism and emotional over-involvement in relatives of early psychosis patients

Mechanisms underlying the manifestation of relatives’ expressed emotion (EE) in the early stages of psychosis are still not properly understood. The present study aimed to examine whether relatives’ psychological distress and subjective appraisals of the illness predicted EE dimensions over-and-above patients’ poor clinical and functional status. Baseline patient-related variables and relatives attributes comprising criticism, emotional over-involvement (EOI), psychological distress, and illness attributions were assessed in 91 early psychosis patients and their respective relatives. Relatives were reassessed regarding EE dimensions at a 6-month follow-up. Relatives’ psychological distress and illness attributions predicted criticism and EOI over-and-above patients’ illness characteristics at both time points. Relatives’ increased levels of anxiety, attributions of blame toward the patients, an emotional negative representation about the disorder, and decreased levels of self-blame attributions predicted EE-criticism at baseline. Relatives’ anxiety and negative emotional representation of the disorder were the only significant predictors of EE-criticism at follow-up, whereas anxiety, attributions of control by the relative and an emotional negative representation about the disorder predicted EE-EOI both at baseline and follow-up assessments. Understanding the components that comprise and maintain EE attitudes should guide early psychosis caregivers in family interventions, enhancing proper management of psychological distress and reduction of negative appraisals about the illness. The prevention of high-EE attitudes over time in a sensitive period such as early psychosis might be critical in shaping the health of caregivers and the outcome of the affected relatives.

Perspectives about Illness, Attitudes, and Caregiving Experiences among Siblings of Persons with Schizophrenia: A Qualitative Analysis

BACKGROUND

Siblings of persons diagnosed with schizophrenia (SPS) are one among the major sources of support for persons with schizophrenia. There is a dearth of psychosocial literature on SPS in India. This qualitative study explored the perspectives about the illness, attitudes, and caregiving experiences of SPS.

MATERIALS AND METHODS

Qualitative audio-recorded interviews were conducted with 15 SPS, purposively selected from a tertiary mental health hospital of Southern India. A general inductive approach was adopted to analyze the qualitative data.

RESULTS

Four broad themes were identified from qualitative data analysis. (1) SPS described several explanatory models of mental illness in terms of causal attributions and treatment care. (2) They had expressed emotion toward their ill siblings, such as criticality, hostility, and emotional over-involvement. (3) They experienced objective and subjective burden while caring for their ill sibling. In spite of all these, (4) they were part of their ill siblings' care in terms of ensuring regular follow-ups and drug adherence and supported their livelihood. They coped up with adaptive as well as maladaptive strategies.

CONCLUSION

SPS provide significant support to their affected siblings. However, they do have non-biomedical models of mental illness and negative attitudes toward patients and experience burden. Hence, psychosocial interventions may help SPS while caregiving for their affected siblings.

Predictors and moderators of burden of care and emotional distress in first-episode psychosis caregivers: results from the GET UP pragmatic cluster randomised controlled trial

AIMS

First-episode psychosis (FEP) is a major life event and can have an adverse impact on the diagnosed individual and their families. The importance of intervening early and providing optimal treatments is widely acknowledged. In comparison to patient groups, literature is scarce on identifying treatment predictors and moderators of caregiver outcomes. This study aimed to identify pre-treatment characteristics predicting and/or moderating carer outcomes, based on data from a multi-element psychosocial intervention to FEP patients and carers (GET-UP PIANO trial).

METHODS

Carer demography, type of family relationship, patient contact hours, pre-treatment carer burden, patient perceptions of parental caregiving and expressed emotion (EE) were selected, a priori, as potential predictors/moderators of carer burden and emotional distress at 9 months post treatment. Outcomes were analysed separately in mixed-effects random regression models.

RESULTS

Analyses were performed on 260 carers. Only patient perceptions of early maternal criticism predicted reports of lower carer burden at follow-up. However, multiple imputation analysis failed to confirm this result. For treatment moderators: higher levels of carer burden at baseline yielded greater reductions in carer emotional distress at follow-up in the experimental group compared with treatment as usual (TAU). Higher levels of perceived EE moderated greater reductions in carer reports of tension in experimental group, compared with TAU, at follow-up. In younger caregivers (<51 years old), there were greater reductions in levels of worry during the baseline to follow-up period, within the experimental group compared with TAU.

CONCLUSION

The study failed to identify significant treatment predictors of FEP carer outcomes. However, our preliminary findings suggest that optimal treatment outcomes for carers at first episode might be moderated by younger carer age, and carers reporting higher baseline levels of burden, and where patients perceive higher levels of negative effect from caregivers.

Ecological Validity of Expressed Emotion in Early Psychosis

Expressed emotion (EE) is an aspect of the family environment that influences the course of multiple forms of psychopathology. However, there is limited research about how EE dimensions [i.e., criticism and emotional over-involvement (EOI)] are expressed in real-world settings. The present study used experience sampling methodology to investigate: 1) the criterion and construct validity of daily-life, momentary measures of criticism and EOI, and 2) the construct and ecological validity of psychometric EE-dimensions as assessed with the self-report Family Questionnaire (FQ). A total sample of 55 relatives (34 relatives of at-risk mental state patients and 21 of first-episode psychosis patients) were prompted randomly six times daily for 1-week to assess their current emotional experiences and cognitive appraisals. Relatives also completed the FQ. Momentary criticism and EOI were significantly associated with the two FQ-EE dimensions respectively, supporting the criterion validity of real-world assessed EE dimensions. As hypothesized, momentary and FQ-EE dimensions were associated with decreased positive affect, as well as with appraisals of less effective coping in daily life. Only momentary EE dimensions were associated with increased momentary negative affect. Partly in contrast with our hypotheses, momentary criticism and FQ-criticism were more consistently related to situational stress and burden than momentary EOI and FQ-EOI. Finally, neither momentary nor FQ-EE dimensions showed distinct patterns of associations with illness attributions. Findings partly support the construct validity of momentary criticism and EOI as well as the construct and ecological validity of the FQ as a sensitive measure of EE dimensions.

Caregiver correlates of patient-initiated violence in early psychosis

Patient-initiated violence may pose a significant risk to the strength and longevity of informal caregiving relationships in psychosis. We aimed to assess caregiver reports of patient-initiated violence in early psychosis and to examine the relationship between violent incidents and appraisals of caregiving, perceived mental wellbeing in caregivers and Expressed Emotion (EE) in the caregiving relationship. Eighty psychosis caregivers were recruited via Early Intervention (EI) psychosis services in London, United Kingdom. Caregivers were questioned about their experiences of patient-initiated violence during the semi-structured Camberwell Family Interview, and completed the Experience of Caregiving Inventory and the RAND SF-36 health survey in a cross-sectional experimental design. One third of the sample reported at least one incident of patient-initiated violence. Reports of violence were associated with poorer mental wellbeing scores amongst caregivers and more negative appraisals of caregiving. Patient-initiated violence also correlated with greater criticism and hostility expressed towards patients, and a rating of high EE in caregiver reports. The results underscore the need to ask explicitly and routinely about the physical safety of caregivers looking after someone with psychosis. Families should be directed towards appropriate interventions to help manage any risk of violence and the likely negative impact on the caregiving relationship.

Self-blame attributions in relatives of people with recent-onset psychosis: Associations with relatives' distress and behavioural control

OBJECTIVES

There is evidence that self-blame is an important predictor of distress and depression in relatives of people with long-term psychosis, but there is limited research investigating the nature and correlates of self-blame in relatives of people with recent-onset psychosis. Self-blame motivates a tendency to engage with others and to repair wrongdoings; it might be that such cognitions also impact on relatives' behaviours towards the patient. This study examined the association between self-blame and psychological distress, and tested the prediction that greater self-blame would be associated with more behavioural control attempts to patients in a sample of relatives of people with recent-onset psychosis.

METHODS

Statements pertaining to self-blame and behavioural control were extracted and rated from 80 interviews with relatives, who also completed the General Health Questionnaire-28. Content analysis was used to examine the nature of self-blame attributions. Regression analyses were used to explore the links between self-blame attributions and distress, and between self-blame and behavioural control in this recent-onset population.

RESULTS

Higher levels of self-blame were associated with more behavioural control attempts, and self-blame predicted relatives' behavioural responses when adjusting for the contribution of control attributions. Self-blame was also linked with distress, but did not emerge as an independent predictor in multivariate analysis. Most relatives who blamed themselves did so for not overseeing their family member's mental health problems properly or for perceiving themselves generally as poor carers.

CONCLUSIONS

This study extends findings related to self-blame to a population of relatives of people with recent-onset psychosis and highlights the possible role of blaming cognitions in promoting interpersonal engagement through behavioural control.

PRACTITIONER POINTS

Self-blaming beliefs were linked with increased distress in relatives of people with recent-onset psychosis; Increased self-blame was associated with more behavioural control attempts; Most relatives blamed themselves for not overseeing their family member's mental health problems properly, and for perceiving themselves generally as poor carers. The cross-sectional study design limits inferences about causality.

Relatives' expressed emotion, distress and attributions in clinical high-risk and recent onset of psychosis

It has been well-demonstrated that Expressed Emotion (EE) in caregivers of schizophrenia patients is related to their illness attributions, but little is known about relatives' cognitive and emotional appraisals at early stages of psychosis. This study examined differences on the relationships of EE with distress and illness attributions in 78 relatives of At-Risk Mental States (ARMS) and First-Episode of Psychosis (FEP) patients, and which of those variables better predicted EE. Criticism and Emotional Over-Involvement (EOI) were associated with distress and with several illness attributions in both groups. Anxiety was more strongly associated with criticism in ARMS than in FEP-relatives, and it was associated with EOI in the ARMS but not in the FEP-group. No differences on the relationships of EE with depression or attributions were found. Furthermore, distress and attributions of blame toward the patients predicted criticism. Attributions of control by the patient and emotional negative representation about the disorder predicted EOI. Findings highlight the need to focus on early family interventions that provide proper information and psychological support in accordance with the illness stage, to help relatives improve their understanding of the disorder, handle difficult thoughts and emotions, reduce negative appraisals, and prevent high-EE over the psychotic process.

Expressed Emotion and behaviourally controlling interactions in the daily life of dyads experiencing psychosis

While research using Experience Sampling Methodology (ESM) suggests that, in general, contact with relatives or friends may be protective for psychotic experiences, contact with high-Expressed Emotion (high-EE) relatives can have adverse consequences for patients. This study investigated whether contact with high-EE relatives, and relatives' behaviourally controlling interactions (BCI) are related to patients' symptoms and to both patients' and relatives' affect when measured using structured diary assessments in the course of everyday life. Twenty-one patients experiencing psychosis and their closest relatives provided synchronized self-reports of symptoms (patients only), affect, dyadic contact and BCI over a 6-days period. Relatives' EE was obtained from Camberwell Family Interviews. Multi-level modeling showed that patients' reports of relatives taking control of them and helping them were associated with increased patient negative affect and symptoms. Relatives' self-reports of nagging, taking control and keeping an eye on the patient were related to fluctuations in relatives' affect. No evidence was found for the moderating effect of EE status on the association between dyadic contact and affect or, in the case of patients, symptoms. When measured using an ecologically valid methodology, momentary behaviourally controlling interactions within dyads experiencing psychosis can impact on patients' affect and symptoms.

Criticism and Depression among the Caregivers of At-Risk Mental State and First-Episode Psychosis Patients

Expressed emotion (EE), especially criticism, is an important predictor of outcomes for the patient for a wide range of mental health problems. To understand complex links between EE and various relevant variables in early phase psychosis, this study examined criticism, distress of caregivers, other patients’, and caregivers’ variables, and links between criticism and these variables in those with at-risk mental state (ARMS) for psychosis and first-episode psychosis (FEP). The participants were 56 patients (mean age 18.8 ± 4.2 years) with ARMS and their caregivers (49.4 ± 5.8 years) and 43 patients (21.7 ± 5.2 years) with FEP and their caregivers (49.3 ± 7.4 years). We investigated criticisms made by caregivers using the Japanese version of the Family Attitude Scale and caregiver depressive symptoms via the self-report Beck Depression Inventory. We also assessed psychiatric symptoms and functioning of the patients. Approximately one-third of caregivers of patients with ARMS or FEP had depressive symptoms, predominately with mild-to-moderate symptom levels, whereas only a small portion exhibited high criticism. The level of criticism and depression were comparable between ARMS and FEP caregivers. The link between criticism, caregivers’ depression, and patients’ symptoms were observed in FEP but not in ARMS caregivers. These findings imply that the interaction between criticism and caregivers’ and patients’ mental states may develop during or after the onset of established psychosis and interventions for the caregivers should be tailored to the patient’s specific stage of illness. Interventions for FEP caregivers should target their emotional distress and include education about patient’s general symptoms.

An Interpersonal CBT Framework for Involving Relatives in Interventions for Psychosis: Evidence Base and Clinical Implications

Working with families in psychosis improves outcomes and is cost effective. However, implementation is poor, partly due to lack of a clear theoretical framework. This paper presents an interpersonal framework for extending the more familiar cognitive behavioral therapy model of psychosis to include the role of relatives' behavior in the process of recovery. A summary of the framework is presented, and the evidence to support each link is reviewed in detail. Limitations of the framework are discussed and further research opportunities highlighted. Clinical implications and a case example are described to show how the framework can be used flexibly to facilitate clinical practice. Our aim is to shift the focus of psychosocial interventions from an individualistic approach to treatment, towards greater involvement of relatives and recognition of the importance of the social environment on mental health.

Patient Outcomes in Association With Significant Other Responses to Chronic Fatigue Syndrome: A Systematic Review of the Literature

Social processes have been suggested as important in the maintenance of chronic fatigue syndrome (also known as myalgic encephalomyelitis; CFS/ME), but the specific role of close interpersonal relationships remains unclear. We reviewed 14 articles investigating significant other responses to close others with CFS/ME and the relationships between these responses and patient outcomes. Significant other beliefs attributing patient responsibility for the onset and ongoing symptoms of CFS/ME were associated with increased patient distress. Increased symptom severity, disability, and distress were also associated with both solicitous and negative significant other responses. Specific aspects of dyadic relationship quality, including high Expressed Emotion, were identified as important. We propose extending current theoretical models of CFS/ME to include two potential perpetuating interpersonal processes; the evidence reviewed suggests that the development of significant other-focused interventions may also be beneficial.

A Case-Series Evaluation of a Brief, Psycho-Social Approach Intended for the Prevention of Relapse in Psychosis

There is a wealth of research into relapse prevention in psychosis; however, specific research into the effectiveness of short-term, self-management strategies aimed to prevent relapse is lacking. This pilot study aimed to evaluate the effects of Sorensen’s ‘Relapse Prevention in Schizophrenia and Other Psychoses’ manual-based therapy (Sorensen, 2006b) with 11 participants in one UK National Health Service Trust. The intervention was delivered over four sessions and interviews were conducted pre and post intervention. The effect of the intervention on measures of hopelessness, perceived control over internal states, and satisfaction were recorded using validated questionnaires at one week, one month and two months follow-up, supported by measures taken from visual analogue scales. Data analysis revealed significant improvements on hopelessness, perceived control over internal states, and satisfaction at one week follow-up, although these results were not maintained at one and two months follow-up. Additionally, the attrition rate meant that results lacked statistical power at one and two months follow-up. The study also considered the clinical significance of the research findings with the Jacobson-Truax (Jacobson & Truax, 1991) method for measuring reliable change. A substantial number of clients attained clinically significant changes with regards to hopelessness and perceived control over internal states. Future research is required in order to evaluate the use of self-management strategies to prevent relapse. It would be valuable to repeat the current study with the additional use of booster sessions in order to assess whether the positive impacts on hopelessness and perceived control over illness can be maintained at the longer term follow up.

The impact of significant other expressed emotion on patient outcomes in chronic fatigue syndrome

Objective: Previous literature has identified the importance of interpersonal processes for patient outcomes in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), particularly in the context of significant other relationships. The current study investigated expressed emotion (EE), examining the independent effects of critical comments and emotional overinvolvement (EOI) in association with patient outcomes. Method: Fifty-five patients with CFS/ME and their significant others were recruited from specialist CFS/ME services. Significant other EE status was coded from a modified Camberwell Family Interview. Patient outcomes (fatigue severity, disability, and depression) were derived from questionnaire measures. Forty-four patients (80%) completed follow-up questionnaires 6-months after recruitment. Results: Significant other high-EE categorized by both high levels of critical comments and high EOI was predictive of worse fatigue severity at follow-up. High-critical EE was associated with higher levels of patient depressive symptoms longitudinally; depressive symptoms were observed to mediate the relationship between high critical comments and fatigue severity reported at follow-up. There were higher rates of high-EE in parents than in partners, and this was because of higher rates of EOI in parents. Conclusions: Patients with high-EE significant others demonstrated poorer outcomes at follow-up compared with patients in low-EE dyads. One mechanism for this appears to be as a result of increased patient depression. Future research should seek to further clarify whether the role of interpersonal processes in CFS/ME differs across different patient-significant other relationships. The development of significant other-focused treatment interventions may be particularly beneficial for both patients and significant others.

Relatives׳ illness attributions mediate the association of expressed emotion with early psychosis symptoms and functioning

The mechanisms underlying the association between expressed emotion (EE) and the prognosis in early psychosis are still not well understood. Based on the attributional model, this study investigated the association of criticism and Emotional Over-Involvement (EOI) with symptoms and functioning in At-Risk Mental State (ARMS) and First-Episode Psychosis (FEP) patients, and whether these associations were mediated by relatives׳ attributions of control and blame. Forty-four patients (20 ARMS and 24 FEP) and their relatives were included. Findings indicated that relatives׳ criticism was associated with positive, negative, and general symptoms. EOI was related to negative and general symptoms. Both indices were related with impaired functioning. Most of the relations between EE indices and illness severity were mediated by relatives׳ attributions of blame toward the patient. Relatives׳ self-blaming attributions and attributions of control over the disorder by either relatives or patients were not associated with patients׳ variables or EE. Findings highlight the importance of family emotional environment in the early stages of psychosis, as well as the mediating role that relatives׳ beliefs can exert in those relationships. Family interventions aimed to assist relatives to change attributions that blame patient should be included in clinical protocols in order to prevent the entrenchment of high-EE.

Caregiver reports of patient-initiated violence in psychosis

OBJECTIVE

Aggressive behaviour in psychosis is not uncommon. Community provision for people with psychosis has left informal caregivers to take on a greater role in their care. However, few studies have explored links between patient-initiated violence in mental health caregiving relationships and caregiver functioning. Our study investigated caregiver reports of aggressive acts committed by their relative with psychosis and their links to caregiver appraisals of the caregiving relationship and caregiver outcomes.

METHOD

Caregivers of patients with a recent relapse of psychosis, recruited to a psychological therapy trial, completed the audiotaped Camberwell Family Interview at baseline. This semi-structured interview includes questions on the quality of the relationship between caregiver and patient, and patient history of violence. Seventy-two transcripts of interviews were assessed for reports of patient-initiated violence.

RESULTS

One-half of the caregiver sample (52.9%) reported an incident of patient-initiated violence during their interview; 62.2% of these involved violence toward themselves, and 24.3% toward property. Reports of patient violence were associated with caregiver ratings of hostility expressed toward patients, lower self-esteem, and emotion-focused coping. People caring on their own were more likely to report incidents of patient violence. Younger patients, males, and inpatients were more frequently identified as having a history of this kind of violence.

CONCLUSIONS

Our findings suggested that caregiver reports of patient-initiated violence in psychosis are not uncommon. Mental health staff need to be aware of the risks of such violence for caregivers of people with psychosis, and consider appropriate procedures for minimizing it.

Positive affect in the family environment protects against relapse in first-episode psychosis

PURPOSE

To evaluate the contribution of positive affect in the family environment to relapse in first episode psychosis.

METHOD

65 service users with a first episode of psychosis were recruited into the current study along with their key relatives. Relatives were interviewed and rated using the Expressed Emotion (EE) measure of warmth, whilst service users completed questionnaires about the positive and negative affects that they perceived from the family environment. Associations between these measures and relapse were examined in a one-year prospective design.

RESULTS

Service users were less likely to relapse within 6 and 12-month follow-up periods when their relatives were rated high on EE warmth, or when they perceived more positive affect from the family. The relationships between service users' perceived positive affect and relapse were preserved after controlling for baseline symptoms, substance use and employment status. Service users' perceptions of positive affect and EE ratings of warmth appeared to be stronger predictors of relapse outcome than criticism and other EE variables.

CONCLUSIONS

Positive family environments may protect against relapse in first episode psychosis. Psychosocial interventions should aim to foster and maintain positive affect in families during the early stages of illness. Further research is needed to understand the mechanisms linking positive affect and outcomes for people recovering from psychosis.
