Social functioning in schizophrenic patients. I. The effects of expressed emotion and family intervention

Assessing the Educational Needs of Family Caregivers of Psychiatric Patients in Jeddah, Saudi Arabia

Background Family caregivers of psychiatric patients in Saudi Arabia and most of the Eastern world are suffering a big burden as a result of their caregiving role. Aim This study aims to assess the need for psychoeducation for family caregivers of psychiatric patients from outpatient clinics in a psychiatric hospital in Jeddah, Saudi Arabia. Materials and methods A cross-sectional descriptive-analytical study was conducted, which included a total of 379 family caregivers providing care to a patient suffering from a psychiatric illness. Results The majority of family caregivers looking after a patient suffering from a psychiatric illness were a brother or sister (20.8%), followed by a son or daughter (20.6%), and lastly, a spouse (10.3%). The top 10 important educational needs of the caregivers included their desire to know about the daily treatment of the patient, followed by how to improve social relationships, and a need for effective stress management. Family caregivers also showed interest in stress and illness. The caregivers' areas of least concern were about the admission of the patients to psychiatric hospitals, recent research on mental illnesses, and how to deal with weight gain. Conclusion The study showed that caregivers demonstrated a need for more experience in how to care for psychiatric patients. Indeed, this has an interrelated impact on the general well-being of both the patient and the caregiver. The study recommends the need for care guidelines to be provided by hospitals from the patient's education department for caregiving to help the family in their daily care.

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.

Ecological momentary assessment of everyday social experiences of people with schizophrenia: A systematic review

INTRODUCTION

Our goal in the current review was to summarize the existing literature on the utility of ecological momentary assessment (EMA) in assessing the social experiences of people with schizophrenia (SZ). We were further interested in examining the associations between EMA-reported social outcomes and traditional assessments of social functioning.

METHODS

We conducted a systematic review of EMA studies published between January 1, 1990 and October 31, 2018 from PubMed and PsycINFO electronic databases. We included EMA studies that assessed social experiences (proportion of time spent alone/with others, affective experiences when with others, social stress, factors related to social experiences) in people with SZ. We included studies that examined associations between laboratory-based, self-report, or clinical assessments of functioning with EMA-reported social experiences.

RESULTS

We identified 22 EMA studies for inclusion in this review. Though heterogeneous in aspects of social experiences assessed, the current literature suggests that people with SZ report more social stress and a preference to be alone when they are with others (nine out of 10 studies). People with SZ report more positive affect when they are with others compared to being alone, and equivalent amounts of positive affect during social experiences as healthy controls (all four studies assessed). Five studies assessed the coherence between functioning assessments and momentary social experiences, with mixed results.

CONCLUSION

We discuss limitations of the literature and future directions. EMA shows promise in assessing more granular aspects of social experience (including social stress and social pleasure) in people with SZ compared to other methods.

Treating Schizophrenia: Open Conversations and Stronger Relationships Through Psychoeducation and Shared Decision-Making

Integrated pharmacological and psychosocial treatments, such as psychoeducation (PE) and shared decision-making (SDM), have been shown to significantly improve outcomes for people living with schizophrenia (PLWS). Underpinning the success of these interventions is a strong therapeutic relationship between PLWS, their carers, and their healthcare team. While many recognize the value of this relationship, implementation of the interventions necessary to facilitate its construction remain low. In this article, we identify the barriers to developing productive therapeutic relationships and explain how PE and SDM, taking into account cultural difference, can improve adherence to treatment, strengthen therapeutic relationships, and ultimately equip patients to achieve better functional outcomes.

Evaluating social skill in individuals with schizophrenia with the brief impression questionnaire (BIQ)

Current social skill assessments for individuals with schizophrenia require extensive administration times, training, and coding procedures, thus limiting their clinical utility. The purpose of this study was to investigate the psychometric properties of the Brief Impression Questionnaire (BIQ), a novel measure designed to utilize immediate impression formation in the assessment of social skill in schizophrenia. An exploratory factor analysis of the BIQ was conducted, and relationships between the extracted factors and measures of social cognition and functioning were assessed. Additionally, we assessed differences on the BIQ between individuals with schizophrenia and control participants. Twenty-two research assistants at three sites rated participants using the BIQ (154 control participants and 218 individuals with schizophrenia). The results revealed identical one-factor structures for both participant groups. For both groups, the BIQ total score was positively associated with performance on social cognitive and everyday functioning assessments. Further, control participants were rated more positively on all BIQ items and received higher BIQ total scores. In the schizophrenia sample, BIQ scores predicted performance on social functioning assessments while controlling for symptom severity. These results indicate that impression formation may be a viable and efficient tool to measure aspects of social cognition and functioning in people with schizophrenia.

Rejection attitudes, poor parental bonding, and stressful life events in heroin addicts' families

BACKGROUND

The influence of family factors on the development and/or on maintenance of heroin addiction still remains unclear.

OBJECTIVES

The aim of this study was to investigate family factors, which might be associated with heroin addiction in a sample of male individuals.

METHODS

A group of 40 heroin addicts' families was compared with a group of 17 families with a member presenting schizophrenia and a group of 27 families with mentally healthy members in regard to (1) parents' rejection attitudes toward their adult child, (2) quality of parental bond, as perceived by the adult child, and (3) stressful life events in the nuclear family.

RESULTS

The main findings showed that the degree of rejection by the fathers in the heroin addicts' families as well as in the subjects with schizophrenia was significantly higher compared to the fathers' degree of rejection in the control group. Moreover, the degree of rejection by mothers in the heroin addicts' families was significantly higher compared to the mothers' degree of rejection in the control group. Heroin addicts reported that they had perceived less care from their fathers than healthy controls. The total number of stressful life events in the nuclear family was higher in the patients with schizophrenia in comparison to the healthy controls. Also, in the heroin addicts' group, a significantly higher number of fathers presented a current or past psychiatric disorder.

CONCLUSIONS

The findings of this study showed the importance of negative family factors in the course of heroin addiction.

Psychosocial Interventions for Schizophrenia

During the past decade there has been a major advance in clinical management of schizophrenic disorders (Falloon & Shanahan, 1990; Lam, 1991; Schooler & Hogarty, 1987). This has resulted from application of strategies based upon a vulnerability-stress model of mental disorders. This considers mental disorders to result from interactions between specific biological vulnerability and non-specific environmental stresses (Falloon & Fadden, 1993).

Therapeutic interventions derived from this model combine biomedical strategies, predominantly optimal pharmacotherapy, with psychosocial strategies that aim to enhance the capacity of the index patient and his/her social network to cope with the impact of environmental stresses on the course of the disorder. Ten controlled studies have been published since 1980 that meet minimal standards of research design, with follow-up for at least 1 year (Bellack, Turner, Hersen, & Luber, 1985; Falloon, 1985; Gunderson et al., 1984; Hogarty et al., 1986; Leff, Kuipers, Berkowitz, Eberlein-Fries, & Sturgeon, 1982; Leff et al., 1989; Malm, 1982; McFarlane, 1990; Tarrier et al., 1988; Wallace & Liberman, 1985). Nine also provided 2-year results. Overall, these studies show that the addition of psychosocial strategies to optimal case management and long-term drug prophylaxis halves the rate of major clinical exacerbations in people suffering from schizophrenia. This benefit is most notable during the first year after a major schizophrenic episode, particularly when the psychosocial interventions encompass patients' immediate social support systems, usually the family or marital household (Falloon, 1985; Hogarty et al., 1986; Leff et al., 1982; Leff et al., 1989; McFarlane, 1990; Tarrier et al., 1988).

Cognitive-Behavioural Family Interventions for Major Mental Disorders

Cognitive-behavioural family interventions for major mental disorder have undergone significant refinement over recent years. This paper reviews the current techniques for assessing mental disorder in the family. The initial task of the therapist is to undertake a comprehensive family assessment, including an assessment of their stress management. Specific information must be obtained about each family member's view of the presenting problems, interaction within the family system, and function in settings outside the family, as well as the family's effectiveness in problem solving and quality of life. Key goals of cognitive-behavioural family therapy are personal goal setting, education, and communication training that enhance the efficiency of family problem solving. The efficiency of cognitive-behavioural therapies in treating major mental disorders is also reviewed in relation to the family's ability to achieve specific goals in therapy and to modify the outcome of major mental illness. Particular attention is given to the strengths and weaknesses of the research, and to possible future research directions. Cognitive-behavioural family interventions are found to be effective in reducing clinical, social, and family morbidity.

New challenges in family interventions for schizophrenia

This review first outlines the rationale and research base supporting the development of family interventions for schizophrenia. The over-riding principles guiding effective family interventions for schizophrenia are then presented, along with the key components (engagement, assessment, education, communication skills training and problem-solving) shared by most family programs in schizophrenia. Meta-analyses demonstrating the efficacy of family interventions in reducing relapse and rehospitalization in schizophrenia are then discussed, along with issues regarding minimal duration of effective treatment, differential benefits of single and multiple family modalities and mixed evidence for the maintenance of treatment effects after termination. The benefits of participation in family-organized, nonprofessional support and education programs are then described. Finally, three issues meriting further study are outlined.

The prognostic role of perceived criticism, medication adherence and family knowledge in bipolar disorders

BACKGROUND

In schizophrenia, high levels of critical comments by significant others are associated with early relapse, especially if medication adherence is sub-optimal. Levels of criticism may be influenced by family knowledge about both the disorder and its treatment. No study has explored whether this combination factors influence outcome in adults with bipolar disorders.

METHODS

Medication adherence was assessed in 81 individuals with bipolar disorder of whom 75 rated perceived criticism by an identified 'significant other' as well as their own perceived sensitivity. 33 (of the 75) had a close family member who agreed to completed an assessment of their knowledge and understanding of bipolar disorders. Psychiatric admissions were then recorded prospectively over 12 months.

RESULTS

Perceived criticism and medication adherence were significant predictors of admission. In the patient-family member dyads (n=33), the odds ratio (OR) for admission was 3.3 (95% confidence intervals 1.3-8.6) in individuals with low levels of medication adherence, high perceived criticism, and a family member with poor knowledge and understanding.

LIMITATIONS

The small sub-sample of patient-family member dyads means those findings require replication. Sensitivity to criticism by professional caregivers may not equate to that by relatives.

CONCLUSIONS

Perceived criticism may be a simple but robust clinical predictor of relapse in mood disorders. High levels of perceived criticism, poor understanding of bipolar disorder by a significant other, and sub-optimal treatment adherence are risk factors for hospitalization in adults with bipolar disorders that are potentially modifiable through the use of strategic psychosocial interventions.

The importance of consumer perceived criticism on clinical outcomes for outpatient African Americans with schizophrenia

This is the second of two studies that tests the impact of family factors on consumer functioning. This study tests the impact of the consumer's perception of being criticized by the family (consumer perceived criticism) on the consumer's clinical functioning. It likewise, concurrently tests the impact that other family factors have on perceived criticism. The sample was ninety-three consumer-family dyads. Results showed that none of the family factors directly contributed to level of perceived criticism, but more consumer perceived criticism was significantly related to higher levels of psychiatric symptoms. The findings suggest that an important component of treatment for symptom stabilization for African American consumers involves perceptions of the family being critical toward the consumer. The finding confirms for a sample of poor outpatient African American consumers what was found in previous research with African Americans. Results are in marked contrast to what impacted consumer psychosocial functioning in the companion study, suggesting that clinical and psychosocial functioning domains are distinct, particularly for African American consumers. This should be reflected in the interventions that are developed for African American consumers and their families.

Risk factors for poor work functioning of persons with schizophrenia in rural China

BACKGROUND

The long-term work performance of persons with schizophrenia in the community is unclear. This study examined the status of long-term work functioning and the predictors of poor work status among patients with schizophrenia in a Chinese rural area.

METHODS

A 10-year follow-up investigation (1994-2004) of a cohort (n = 510) of persons with schizophrenia was conducted in Xinjin County, Chengdu, China.

RESULTS

Compared with baseline data, work functioning of patients with schizophrenia deteriorated after 10 years. The rates of not working increased significantly from 12.0% in 1994 to 23.0% in 2004. Bivariate analyses showed that the poor work functioning in 2004 was significantly associated with male gender, older age, older age of first onset, higher level of education, longer duration of illness, lower family economic status, lack of caregivers, poor work status in 1994, living in shabby or unstable house, marked symptoms, and higher score on the Social Disability Screening Schedule (SDSS). In multiple logistic regression analyses, higher score of SDSS and poor work status in 1994 were identified as unique predictors of poor work status in 2004.

CONCLUSION

The status of work functioning of persons with schizophrenia decreased over the course of the illness. The risk factors for poor work functioning and specific socio-cultural environment should be considered in planning community mental health services and rehabilitation for these patients.

Expressed emotion and caregiver burden in patients with schizophrenia

BACKGROUND

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

AIM

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

MATERIALS AND METHODS

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

RESULTS AND CONCLUSION

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

Psychoeducation for schizophrenia

BACKGROUND

Schizophrenia can be a severe and chronic illness characterised by lack of insight and poor compliance with treatment. Psychoeducational approaches have been developed to increase patients' knowledge of, and insight into, their illness and its treatment. It is supposed that this increased knowledge and insight will enable people with schizophrenia to cope in a more effective way with their illness, thereby improving prognosis.

OBJECTIVES

To assess the effects of psychoeducational interventions compared with standard levels of knowledge provision.

SEARCH STRATEGY

We searched the Cochrane Schizophrenia Group Trials Register (February 2010).

SELECTION CRITERIA

All relevant randomised controlled trials focusing on psychoeducation for schizophrenia and/or related serious mental illnesses involving individuals or groups. We excluded quasi-randomised trials.

DATA COLLECTION AND ANALYSIS

At least two review authors extracted data independently from included papers. We contacted authors of trials for additional and missing data. We calculated risk ratios (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data. We used a fixed-effects model for heterogeneous dichotomous data. Where possible we also calculated the numbers needed to treat (NNT), as well as weighted means for continuous data.

MAIN RESULTS

This review includes a total of 5142 participants (mostly inpatients) from 44 trials conducted between 1988 and 2009 (median study duration ˜ 12 weeks, risk of bias - moderate). We found that incidences of non-compliance were lower in the psychoeducation group in the short term (n = 1400, RR 0.52 CI 0.40 to 0.67, NNT 11 CI 9 to 16). This finding holds for the medium and long term. Relapse appeared to be lower in psychoeducation group (n = 1214, RR 0.70 CI 0.61 to 0.81, NNT 9 CI 7 to 14) and this also applied to readmission (n = 206, RR 0.71 CI 0.56 to 0.89, NNT 5 CI 4 to 13). Scale-derived data also suggested that psychoeducation promotes better social and global functioning. In the medium term, treating four people with schizophrenia with psychoeducation instead of standard care resulted in one additional person showing a clinical improvement. Evidence suggests that participants receiving psychoeducation are more likely to be satisfied with mental health services (n = 236, RR 0.24 CI 0.12 to 0.50, NNT 5 CI 5 to 8) and have improved quality of life.

AUTHORS' CONCLUSIONS

Psychoeducation does seem to reduce relapse, readmission and encourage medication compliance, as well as reduce the length of hospital stay in these hospital-based studies of limited quality. The true size of effect is likely to be less than demonstrated in this review - but, nevertheless, some sort of psychoeducation could be clinically effective and potentially cost beneficial. It is not difficult to justify better, more applicable, research in this area aimed at fully investigating the effects of this promising approach.

Family intervention for schizophrenia

BACKGROUND

People with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of emotions. Forms of psychosocial intervention, designed to reduce these levels of expressed emotions within families, are now widely used.

OBJECTIVES

To estimate the effects of family psychosocial interventions in community settings for people with schizophrenia or schizophrenia-like conditions compared with standard care.

SEARCH STRATEGY

We updated previous searches by searching the Cochrane Schizophrenia Group Trials Register (September 2008).

SELECTION CRITERIA

We selected randomised or quasi-randomised studies focusing primarily on families of people with schizophrenia or schizoaffective disorder that compared community-orientated family-based psychosocial intervention with standard care.

DATA COLLECTION AND ANALYSIS

We independently extracted data and calculated fixed-effect relative risk (RR), the 95% confidence intervals (CI) for binary data, and, where appropriate, the number needed to treat (NNT) on an intention-to-treat basis. For continuous data, we calculated mean differences (MD).

MAIN RESULTS

This 2009-10 update adds 21 additional studies, with a total of 53 randomised controlled trials included. Family intervention may decrease the frequency of relapse (n = 2981, 32 RCTs, RR 0.55 CI 0.5 to 0.6, NNT 7 CI 6 to 8), although some small but negative studies might not have been identified by the search. Family intervention may also reduce hospital admission (n = 481, 8 RCTs, RR 0.78 CI 0.6 to 1.0, NNT 8 CI 6 to 13) and encourage compliance with medication (n = 695, 10 RCTs, RR 0.60 CI 0.5 to 0.7, NNT 6 CI 5 to 9) but it does not obviously affect the tendency of individuals/families to leave care (n = 733, 10 RCTs, RR 0.74 CI 0.5 to 1.0). Family intervention also seems to improve general social impairment and the levels of expressed emotion within the family. We did not find data to suggest that family intervention either prevents or promotes suicide.

AUTHORS' CONCLUSIONS

Family intervention may reduce the number of relapse events and hospitalisations and would therefore be of interest to people with schizophrenia, clinicians and policy makers. However, the treatment effects of these trials may be overestimated due to the poor methodological quality. Further data from trials that describe the methods of randomisation, test the blindness of the study evaluators, and implement the CONSORT guidelines would enable greater confidence in these findings.

Effect of aripiprazole versus haloperidol on PANSS Prosocial items in early-episode patients with schizophrenia

BACKGROUND AND AIM

Improving social functioning is critically important in early-episode schizophrenia, if patients are to achieve functional recovery. This post-hoc, pooled analysis of two studies compared the effect of aripiprazole versus haloperidol on social functioning in early-episode schizophrenia.

METHODS

Data were pooled from two 52 week, randomized (2:1), double-blind, multicenter studies involving 1294 patients with chronic schizophrenia who were in an acute psychotic episode and had a history of positive antipsychotic response during previous episodes. The early-episode group was defined as patients who are <or=40 years of age with <or=5 years' duration of illness. Social functioning was assessed by mean change from baseline on the PANSS Prosocial subscale (ANCOVA and LOCF), comprising six PANSS items, and the Modified Prosocial subscale, comprising four PANSS items. Measurements were taken at approximately monthly intervals for up to 1 year.

RESULTS

Aripiprazole (n=237) demonstrated significant improvement versus haloperidol (n=123) as early as Week 18 on both the Prosocial subscale (-4.75 versus -3.78, p<0.05) and on the Modified Prosocial subscale (-3.16 versus -2.28, p<0.05). Patients receiving aripiprazole continued to show similar significant improvement versus haloperidol at all remaining timepoints through Week 52 using the Modified Prosocial subscale, but less consistent improvement with the Prosocial subscale. Significant advantage for the aripiprazole-treated patients was observed at Weeks 46 and 52 (endpoint) with both subscales.

CONCLUSION

In patients with early-episode schizophrenia, aripiprazole demonstrates greater improvement than haloperidol on PANSS items related to social functioning. The cognitive and functional implications of these findings remain to be clarified in future studies.

Controversies and Growing Points in Cognitive-Behavioural interventions for People with Schizophrenia

The growing “family” of cognitive-behavioural interventions has made impressive strides in the management of schizophrenia over the last decade. This paper critically reviews the advances that have been made and examines some of the controversies and difficulties encountered in the application of this approach and suggests areas for future growth and research. Future developments in family interventions, early intervention, the management of hallucinations and the potential utility of a form of psychotherapy to treat secondary depression and prevent suicide, are covered in depth. Service structures to integrate these interventions, their timing and duration are considered. It is suggested that the marriage of case management and psychosocial interventions in particular is now overdue.

Behavioural Psychotherapy and Schizophrenia: The Past, the Present, and the Future

Behavioural therapists have been involved with the management of schizophrenia since the emergence of the discipline in the 1950s. It has been stated recently that behaviour therapists have lost interest in serious mental illness. However, in the last few years great advances have been made in behavioural approaches to the management of schizophrenia. Controlled trials of family management methods have indicated that: relapse rates can be reduced, the patient's social functioning increased and family burden decreased. These approaches also have economic benefits over traditional services. Furthermore, other methods, such as early signs monitoring followed by early intervention and self-management of drug resistant residual symptoms, have also shown promise. The development of these innovative behavioural approaches is especially important in an era of community based mental health services.

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.

Reliability, validity and ability to detect change of the clinician-rated Personal and Social Performance scale in patients with acute symptoms of schizophrenia

OBJECTIVE

To describe the measurement properties of the Personal and Social Performance scale (PSP), a clinician-reported measure of severity of personal and social dysfunction, in subjects with acute symptoms of schizophrenia.

METHODS

Pooled data from three paliperidone extended-release clinical studies (n = 1665) and data from a separate noninterventional, cross-sectional, validation study (n = 299) were analyzed.

RESULTS

The PSP showed good interrater (intraclass correlation coefficient [ICC] = 0.87) and test-retest (ICCs > 0.90) reliability. Pearson correlation coefficient for association between baseline PSP and Positive and Negative Syndrome Scale (PANSS) total scores was -0.32 for subjects assessed by the same rater and -0.29 for subjects assessed by different raters, suggesting low overlap in measurement constructs between the PANSS and PSP. Spearman Rank correlation coefficient for association between baseline PSP and Clinical Global Impression-Severity (CGI-S) scores was -0.51 with the same rater and -0.15 with different raters. Hypothesized relationships between the PSP and the PANSS or CGI-S based on levels of disease severity were prospectively defined. These hypotheses were confirmed by analyses showing statistically significant differences between baseline mean PSP scores in subjects grouped by severity rating on the CGI-S (mild or less vs. at least moderate) (p < 0.001) and the PANSS ('low symptom severity' vs. 'high symptom severity') (p = 0.005). The PSP was sensitive to change based on statistically significant correlations between change in the PSP and change in the CGI-S (p < 0.001) and the PANSS (p < 0.001). Limitations of analyses include pooling data across studies, interrater reliability assessment in the validation study only, post hoc assessment of test-retest reliability in the paliperidone ER studies, different raters for the PSP and PANSS not specified in the paliperidone ER studies, PSP validity assessment based on the PANSS and the CGI-S as comparators rather than another social function instrument.

CONCLUSION

These initial reliability and validity assessments suggest the PSP has promise as a measure of social functioning in patients with acute symptoms of schizophrenia.

Burden and coping strategies in mothers of patients with schizophrenia in Japan

AIM

The present study was conducted to identify factors contributing to burden of care in 57 mothers caring for patients with schizophrenia.

METHODS

Members of the Federation of Families of People with Mental Illness in Nagasaki Prefecture were evaluated using well-validated scales to evaluate burden of care (eight-item short version of the Japanese version of the Zarit Caregiver Burden Interview), general health status (General Health Questionnaire 12-item version), difficulty in life, coping strategies, emotional support, and understanding of mental illness and disorders.

RESULTS

Burden of care was significantly associated with general health status and difficulty in life.

CONCLUSION

On multiple regression it was found that 'social interests' and 'resignation', both of which are the subscales of coping strategies, exerted significant and independent effects with respect to burden of care.

Adjunctive psychosocial therapies for the treatment of schizophrenia

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

The burden of schizophrenia on caregivers: a review

Schizophrenia is a disabling, chronic psychiatric disorder that poses numerous challenges in its management and consequences. It extols a significant cost to the patient in terms of personal suffering, on the caregiver as a result of the shift of burden of care from hospital to families, and on society at large in terms of significant direct and indirect costs that include frequent hospitalizations and the need for long-term psychosocial and economic support, as well as life-time lost productivity. 'Burden of care' is a complex construct that challenges simple definition, and is frequently criticized for being broad and generally negative. Frequently, burden of care is more defined by its impacts and consequences on caregivers. In addition to the emotional, psychological, physical and economic impact, the concept of 'burden of care' involves subtle but distressing notions such as shame, embarrassment, feelings of guilt and self-blame. The early conceptualization of 'burden of care' into two distinct components (objective and subjective) has guided research efforts until the present time. Objective burden of care is meant to indicate its effects on the household such as taking care of daily tasks, whereas subjective burden indicates the extent to which the caregivers perceive the burden of care. Research contributions in later years (1980s to the present) have added more depth to understanding of the construct of burden of care by exploring important determinants and factors that likely contribute or mediate the caregiver's perception of burden of care. Several studies examined the role of gender, and reported that relatives of male patients with schizophrenia frequently experience more social dysfunction and disabilities than those of female patients. Similarly, a number of other studies documented the contribution of ethnicity and cultural issues to subjective burden of care. Although there is no complete agreement on whether a specific cluster of psychotic symptoms has the most impact on a caregiver's burden of care, there is agreement that the severity of symptoms increases it. An extensive literature concerning family interventions in schizophrenia has demonstrated the positive impact of various family interventions in improving family environment, reducing relapse and easing the burden of care. Although the evidence of such positive impact of family interventions in schizophrenia is well documented, such interventions are neither widely used nor appropriately integrated in care plans, and are frequently underfunded. Although the cost of caregiving is considered to be significant, there are no reliable estimates of the costs associated with such care. The majority of available literature categorized the cost of burden of care among the indirect costs of schizophrenia in general. In recent years, attempts to compare the costs of caregiving in several countries have been reported in the evolving literature on this topic. 'Burden of care' as a complex construct certainly requires the development of appropriate methodology for its costing. In achieving a balance between the patients' and caregivers' perspectives, caregivers have to be included in the care plan and adequate information and support extended to the family and caregivers. Access to better treatment for patients, including medications, psychosocial interventions and rehabilitation services, are important basic elements in easing the burden on caregivers. Other measures such as availability of crisis management, provision of legally mandated community treatment to avert hospitalization, and well informed and balanced advocacy are also important. Although research efforts have been expanded in the last 3 decades, an urgent need exists for enhancing such efforts, particularly in the development and evaluation of effective family interventions strategies. There is also a need for continued improvement in the delivery of psychiatric services to the severely psychiatrically ill and their families. As there is a lack of reliable cost information about the family burden of care specific to schizophrenia, there is an urgent need to develop reliable approaches that can generate data that can inform in policy making and organization of services.

Social functioning as an outcome measure in schizophrenia studies

OBJECTIVE

Deficits in social functioning are a core feature of schizophrenia.

METHOD

A literature search of English language articles published between January 1990 and December 2006 was undertaken to identify: i) scales used most frequently to assess social functioning in schizophrenia; and ii) the most frequently used social functioning scales in randomized, controlled trials of antipsychotics. A further search (without time limits) examined their psychometric properties.

RESULTS

A total of 301 articles employed social functioning scales in the assessment of schizophrenia. These contained 87 potentially relevant measures. Only 14 randomized, controlled studies of antipsychotic agents were identified that examined social functioning. Scales varied greatly in terms of measurement approach, number and types of domains covered and scoring systems. A striking lack of data on psychometric properties was observed.

CONCLUSION

Limited consensus on the definition and measurement of social functioning exists. The Personal and Social Performance Scale is proposed as a useful tool in future research.

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.

The potential impact of the recovery movement on family interventions for schizophrenia: opportunities and obstacles

Many types of family interventions have been found to be effective in reducing exacerbations in schizophrenia; some also improve consumer social functioning and reduce family burden. Regardless of their origins, these interventions share a number of common features, such as showing empathy for all participants, providing knowledge about the illness, assuming a nonpathologizing stance, and teaching communication and problem-solving skills. Importantly, these family interventions have many characteristics that are consistent with the growing recovery movement in mental health in that they are community-based, emphasize achieving personally relevant goals, work on instilling hope, and focus on improving natural supports. Nevertheless, these interventions are generally reflective of older models of serious and persisting psychiatric illnesses that are grounded in a "patient being treated for a chronic illness" rather than a "consumer assuming as much responsibility as possible for his/her recovery" stance. These interventions could be made more consistent with recovery principles by (1) expanding the definition of family to include marital, parenting, and sibling relationships, (2) identifying better ways to match consumers with treatments, (3) broadening the research focus to include systems change that promotes making family members a part of the treatment team (with the consumer's consent), and (4) overcoming implementation obstacles that preclude access to effective family interventions for most consumers and their relatives.

Carers and confidentiality in mental health care: considering the role of the carer's assessment: a study of service users', carers' and practitioners' views

Relatives or carers of people with mental health problems have criticised professionals for their failures to share information with them. This article reports on a multiple method study comprising a policy search, a survey of service users, carers and professionals, and stakeholder interviews and group events. The study found few policies that addressed the principles underpinning information sharing with carers. However, examples of good practice in professional involvement of carers that took account of carer rights and responsibilities emerged from the research. This suggests the relevance of the carer's assessment, a carer's right to an assessment of his or her circumstances and wishes in assisting understanding of the care context and enhancing appropriate information sharing between professionals and carers.

A pilot validation study of a new measure of activity in psychosis

BACKGROUND

Wing and Brown [Wing JK and Brown GW (1970) Institutionalism and schizophrenia: a comparative study of three mental health hospitals 1960-1968. Cambridge University Press, London] demonstrated a clear relationship between activity and clinical improvement, using time budget methodology with people with psychosis. However, existing time budget measures are demanding to complete, and simpler, check-box measures of activity rely on subjective frequency judgements and do not include the full range of activities in which an individual might be involved. We report on a pilot validation of a simplified time budget measure of activity levels for routine use as a measure of change with people with psychosis.

METHODS

Forty-two participants living in the local community with a schizophrenia spectrum diagnosis were grouped according to length of illness and, within the longer duration group, into high/low activity. All completed the time budget. On a second occasion, 15 participants also completed the subscales of the Social Functioning Scale (SFS) (Br J Psychiatry 157:853-859, 1990) to assess construct validity, and 15 completed the time budget to assess test-retest reliability.

RESULTS

The time budget discriminated between duration and activity level groups and showed good inter-rater reliability and test-retest reliability. On the SFS, correlations with subscales measuring withdrawal, activities of daily living and employment were found.

CONCLUSIONS

Results indicate that our measure is tapping the activity component of social functioning. A larger scale validation study and investigation of sensitivity to change is underway.

Expressed emotion and social functioning in chronic schizophrenia

The aim of this study was to reveal the relationships between family expressed emotion (EE), family evaluations of social functioning, and the psychopathologic symptoms of patients with schizophrenia. We examined whether EE influenced the social functioning of patients with schizophrenia. Forty-four subjects with schizophrenia and 82 of their relatives participated in this study. The Five-Minute Speech Sample (FMSS) was conducted to evaluate EE, and subjects were divided into high-EE and low-EE groups. The Positive and Negative Symptom Scale (PANSS) was used to assess symptom severity. Social functioning was compared between the two groups using the Social Functioning Scale (SFS). No differences in symptom severity or social adjustment, as evaluated by a global assessment of functioning, were observed between the two groups. However, the high-EE relatives tended to evaluate the social functioning of the schizophrenia patient in their family as being rather low and showed a strong dissatisfaction with the patient's social withdrawal and level of independence (competence). Furthermore, low-EE relatives in high-EE families showed the same tendencies. The family members who were evaluated as low-EE relatives in a high-EE family were dissatisfied with the patient's social withdrawal, level of independence (competence), and also their interpersonal functioning. In the chronic stable phase of schizophrenia, the attention of the family members may be more directed towards changes in social functioning; thus, the EE may reflect a family's attitude towards improvements in the patient's social functioning.

Relationship between family attitudes and social functioning in schizophrenia: a nine-month follow-up prospective study in Spain

The objective was to study the relationship between family attitudes and social functioning in schizophrenia. A cohort of 80 patients was followed-up for 9 months after their hospitalization. The relatives' critical attitude and poor empathic attitude were measured by means of the Semantic Differential and the Questionnaire of Empathy, respectively. Time of useful work and social relations of the patients were measured before admission and at the end of follow-up. Symptoms, premorbid adjustment, and other course and demographic factors were also measured. Significant relationships were found between the relatives' poor empathic attitude and the patients' occupational functioning and social relations. These associations were maintained after controlling for the effects of other prognostic factors. These results suggest that empathy in the relative is an independent predictor of social functioning in people with schizophrenia. Different attitudinal dimensions of family attitudes might show different relationships with the social and clinical outcomes in this disorder.

Expressed emotion at first-episode psychosis: investigating a carer appraisal model

BACKGROUND

Even at the first episode of psychosis, high expressed emotion (EE) characterises over half of patient-carer relationships. This study compared a carer appraisal model of EE with the ability of illness factors to predict EE at the first episode.

AIMS

To investigate the utility of a carer appraisal model of EE in first-episode psychosis.

METHOD

We compared high- and low-EE carers of people who had first-episode psychosis (n=46).

RESULTS

High EE in carers was associated with higher avoidant coping, higher subjective burden and lower perceived patient interpersonal functioning. Patient illness factors and carers' distress levels were not associated with EE.

CONCLUSIONS

Even at the first episode, carers' psychological appraisal, not patient illness factors, is influential in determining high EE. Carers' appraisal of their situation should be a primary target to lower or prevent high EE in early intervention for psychosis.

Maximizing the synergy between pharmacotherapy and psychosocial therapies for schizophrenia

Although the traditional antipsychotic medications were a major advancement in schizophrenia therapeutics and made possible the era of deinstitutionalization, just maintaining a patient out of the hospital no longer can be viewed as the final goal of treatment. Most patients are able to maintain outpatient status despite persistent psychotic symptoms, pervasive negative symptoms and poor social competence. It is hoped that the availability of the atypical antipsychotic drugs will improve significantly compliance, treatment of symptoms, and possibly relapse rates and overall outcome. It should be the norm and not the exception for patients to be treated with these new medications as early as possible in their illness. The clinician should not be complacent and quick to accept persistent psychosis, and patients with various forms of treatment resistance should be tried early in the course of illness with clozapine (or other medications as they become available if they show superiority for treatment-resistant patients). Pharmacologic interventions aimed at deficit symptoms may become available in the future. Psychosocial interventions have a place in the modern therapeutic armamentarium. Relatively simple sustained family interventions and more comprehensive ACT programs are effective for relapse prevention and reduction of the "revolving door syndrome," whereas patients with psychosis nonresponsive to medication may benefit from new modalities of CBT. For patients with persistent negative symptoms and limited social competence, SST is indicated where available, and even in places where staff may be limited and social skills and other programs difficult to implement, family psychoeducational interventions can be carried out to good effect.

[Social performance expectations in psychiatric patients of a general hospital ward]

OBJECTIVE

To prospectively assess the performance of socially expected activities of psychiatric patients in the first year after their discharge from a psychiatric ward of a general hospital. Also, to evaluate the patients' and their family' expectations on the former's performance.

METHODS

The study was carried out in a general hospital in Ribeirão Preto, Brazil. The Katz Scale was applied to the patient and their family informer at the time of hospitalization regarding to the week preceding admission, and at one, six and 12 months after hospital discharge, regarding to the preceding week. Of the 86 pairs who were initially included in the study, 55 patients (33 women and 22 men) and their respective family informers completed the study. Performance scores and expectations were compared using variance (ANOVA) and t-student test.

RESULTS

Expectation did not show significant variations either in the patient's evaluation or in the family's evaluation. According to both evaluations, expectation was significantly higher than performance. A significant improvement in the performance of socially expected activities was observed as early as one month after discharge compared to the pre-admission period and was unchanged along the first year in both evaluations of the patient and their family.

CONCLUSIONS

These results suggest that admission to a psychiatric ward of a general hospital, in addition to reducing the psychiatric symptoms, contributed to improving the performance of socially expected activities. The average level of performance was unchanged throughout the first year after discharge, although demographic and medical variables can influence these results.

Validity of a five-minute speech sample for the measurement of expressed emotion in the families of Japanese patients with mood disorders

Both the Camberwell Family Interview (CFI) and the Five-Minute Speech Sample (FMSS) have been used to define expressed emotion (EE), but the validity of the FMSS relative to the CFI in mood disorders has not been evaluated. In our study, the FMSS and the CFI were performed on the same day in close family members of inpatients with mood disorders within 2 weeks after their admission. The ratings obtained from the CFI were then used to estimate the validity of the FMSS, which was defined by sensitivity and specificity on the basis of the overall evaluation of EE. Validity was also assessed by including borderline ratings of 'low EE' in the category of 'high EE.' Based on the overall evaluation, sensitivity and specificity were 66.7 and 96.8%, respectively. When borderline low EE was included in high EE, the sensitivity and specificity were 100 and 90.3%, respectively. The validity of definitions of EE by the FMSS relative to the CFI was high in mood disorders. Evaluation of EE by the FMSS, which is clinically applicable to patients with mood disorders, is feasible. The validity of this approach is enhanced when families defined as 'borderline low EE' are included in the high-EE category.

Family attitude scale: measurement of criticism in the relatives of patients with schizophrenia in Japan

Expressed emotion (EE) is traditionally measured with the Camberwell Family Interview (CFI), but the CFI requires considerable time for both execution and evaluation. As an alternative, we investigated the validity of the Family Attitude Scale (FAS), a questionnaire developed for the measurement of EE. The CFI, the FAS, the General Health Questionnaire (GHQ), and the Five-Minute Speech Sample (FMSS) were administered in 57 members of the families of 41 patients with acute episodes of schizophrenia. The relative sensitivity and specificity of EE assessment with the FAS compared with the criticism component of the CFI were 100% and 88.5%, respectively. EE assessment based on criticism as assessed with the FMSS compared with the CFI had a sensitivity of 40.0% and a specificity of 90.4%. The GHQ score tended to be higher in the high-scoring FAS group than in the low-scoring FAS group. The FAS showed excellent validity for the measurement of critical aspects of family attitudes, and the FAS score reflected the state of psychological health of the families.

Psychoeducation for schizophrenia

BACKGROUND

Schizophrenia can be a severe and chronic illness characterised by lack of insight and poor compliance with treatment. Psychoeducational approaches have been developed to increase patients' knowledge of, and insight into, their illness and its treatment. It is supposed that this increased knowledge and insight will enable people with schizophrenia to cope in a more effective way with their illness, thereby improving prognosis.

OBJECTIVES

To assess the effects of psychoeducational interventions compared to the standard levels of knowledge provision.

SEARCH STRATEGY

Electronic searches of CINAHL (1982-1999), The Cochrane Library CENTRAL (Issue 1, 1999), The Cochrane Schizophrenia Group's Register (May 2001), EMBASE (1980-1999), MEDLINE (1966-1999), PsycLit (1974-1999), and Sociofile (1974-1999) were undertaken. These were supplemented by cross-reference searching and personal contact with authors of all included studies.

SELECTION CRITERIA

All relevant randomised controlled trials focusing on psychoeducation for schizophrenia and/or related serious mental illnesses involving individuals or groups. Quasi-randomised trials were excluded.

DATA COLLECTION AND ANALYSIS

Data were extracted independently from included papers by at least two reviewers. Authors of trials were contacted for additional and missing data. Relative risks (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data were calculated. A random effects model was used for heterogeneous dichotomous data. Where possible the numbers needed to treat (NNT) were also calculated. Weighted or standardised means were calculated for continuous data.

MAIN RESULTS

Ten studies are included in this review. All studies of group education included family members. Compliance with medication was significantly improved in a single study using brief group intervention (at one year) but other studies produced equivocal or skewed data. Any kind of psychoeducational intervention significantly decreased relapse or readmission rates at nine to 18 months follow-up compared with standard care (RR 0.8 CI 0.7-0.9 NNT 9 CI 6-22). Several of the secondary outcomes (knowledge gain, mental state, global level of functioning, expressed emotion in family members) were measured using scales that are difficult to interpret. Generally, however, findings were consistent with the possibility that psychoeducation has a positive effect on a persons' well being. No impact was found on insight, medication related attitudes or on overall satisfaction with services of patients or relatives but these findings rested on very few studies. Health economic outcome was only measured in one study and data were skewed. It was not possible to analyse whether different duration or formats of psychoeducation influenced effectiveness.

REVIEWER'S CONCLUSIONS

Evidence from trials suggests that psychoeducational approaches are useful as a part of the treatment programme for people with schizophrenia and related illness. The fact that the interventions are brief and inexpensive should make them attractive to managers and policy makers. More well-designed, conducted and reported randomised studies investigating the efficacy of psychoeducation are needed.

The challenge of psychiatric rehabilitation in schizophrenia

Many persons with schizophrenia continue to struggle with psychiatric symptoms and poor social adjustment, even when prescribed appropriate doses of antipsychotic medications. Psychiatric rehabilitation involves using psychosocial interventions to minimize symptoms and relapse while maximizing social functioning in schizophrenia. In this article, the scope of psychiatric rehabilitation is first defined and then the rationale for psychiatric rehabilitation is presented. The challenges to implementation of psychiatric rehabilitation strategies are next articulated. Finally, brief reviews of the four most empirically validated psychiatric rehabilitation techniques are presented.

Comorbidity fails to account for the relationship of expressed emotion and perceived criticism to treatment outcome in patients with anxiety disorders

This study was designed to test the hypothesis that comorbidity mediates the relationship between expressed emotion, perceived criticism (PC), and treatment outcome in anxiety disorders. Although comorbid major depression and Axis II traits were related to poor outcome in agoraphobic and obsessive-compulsive outpatients, these variables did not prove to be mediators of drop-out or treatment outcome. A secondary aim was to examine whether PC predicted change in symptoms of depression. Even when posttreatment anxiety severity and comorbidity were controlled, PC accounted for a significant proportion of the variance in change on the Symptom Checklist-90-R depression scale.

Social functioning and the course of early-onset schizophrenia: five-year follow-up of a psychosocial intervention

BACKGROUND

Schizophrenia implies severe social impairments. Since the treatment of patients with schizophrenia shifted from long-term hospital admissions to community services, research on social functioning has become increasingly important.

AIMS

Follow-up assessment of social functioning in young patients with schizophrenia during a 5-year period after intervention.

METHOD

During intervention, families were randomised into two conditions: standard intervention and standard plus family intervention.

RESULTS

Although no differential treatment effect with regard to the course of the illness was found, patients from the standard plus family intervention condition stayed for fewer months in institutions for psychiatric patients than patients from the standard intervention condition.

CONCLUSIONS

Family intervention has helped parents to support their children, thereby diminishing institutional care.

A review of expressed emotion research in health care

Much research has been carried out on the impact of family relationships on the development and course of different illness. Research on Expressed Emotion (EE) developed out of studies of the impact of family members on patients with schizophrenia, and has provided us with a robust measure of relatives' emotional attitudes towards patients, which has now been applied in the study of numerous psychiatric and medical illnesses. This review outlines the history of EE research in schizophrenia, and discusses the evidence for the association between family EE and the course of schizophrenic illness. Some of the factors which might moderate the association between EE and illness course are outlined and the issues of the meaning and development of EE are discussed in the light of recent theoretical advances. The application of the EE methodology in other psychiatric and medical conditions is then reviewed and conclusions are drawn about the extent to which EE predicts illness course in conditions other than schizophrenia. Consideration is given to the ways in which the application of the paradigm to a variety of illnesses or conditions with different features can enhance our understanding of the EE construct.
