Predictors of general quality of life and the mediating role of health related quality of life in patients with schizophrenia

Quality of life for people with psychiatric disabilities employed in extended employment programs in two Arab towns in Israel: an exploratory study

Introduction

This study aims to examine the quality of life (QOL) for people with psychiatric disabilities who are engaged in extended employment programs (homogeneous versus heterogeneous) in the Arab-populated Triangle Area of Israel. The homogeneous program participants are exclusively Arab while the heterogeneous program includes both Arabs and Jews.

Methods

Quantitative research study of 104 adults with psychiatric disabilities engaged in two communal extended employment programs. Participants completed demographic (age (years), gender, marital status (married, widowed/separated, married, single), religion (Muslim, Jewish, Christian), dichotomous nationality variable (Jewish/Arab), and years of education) and employment questionnaires (length of time in the employment program, number of working days/h and salary satisfaction); SF 12 Scale; and The Personal Wellbeing Index questionnaire. Two-sample T-Test, exploratory factor analysis and multiple linear regressions were conducted for tracking the differences between participants in homogeneous and heterogeneous programs.

Results

A significant difference was found between the programs in two QOL components, insofar as satisfaction with the standard of living, together with health satisfaction were rated higher for participants in the heterogeneous program than for their homogeneous program counterparts. Furthermore, the results indicate that physical health and gender were the most important variables in explaining QOL in both programs, while the employment variables were not significant.

Discussion

Since the research findings show that the employment-related-items aren't significant in predicting the employees' QOL, the definition and suitability of extended employment environments as a mental health service must be reexamined. Cultural elements may also have an impact on QOL when the programs are located in a traditional town, with gender playing a key role. The family's role is pivotal in traditional societies, influencing an individual's ability to participate in employment programs and the support they receive. In patriarchal societies, there can be added pressure on men with psychiatric disabilities to conform to societal expectations. Given the general lack of health awareness in Arab communities, there is a need to develop additional projects or incorporate physical health improvement as a rehabilitation goal when working with individuals with psychiatric disabilities, regardless of the type of community rehabilitation program.

The influence of romantic relationships on mental wellbeing for people who experience psychosis: A systematic review

PURPOSE

Whilst it is generally accepted that supportive relationships facilitate recovery from psychosis, much less is known about the role of romantic relationships in people with psychosis. This review aimed to synthesise quantitative literature regarding the impact of romantic relationships on the mental health and general wellbeing of people who experience psychosis.

METHOD

A systematic review of electronic databases (PsychINFO, PubMed, Web of Science) was carried out using search terms relating to psychosis and romantic relationships. Papers were selected for inclusion by independent reviewers. Quality assessment was completed and a narrative synthesis produced.

RESULTS

Fifty-eight studies reporting the association between romantic relationships and psychotic symptoms, depression, posttraumatic stress disorder, suicidality, quality of life, satisfaction with life and self-esteem were included. Results were mixed but indicated having a romantic partner may be associated with reduced positive and negative symptoms of psychosis, but increased depressive symptoms. Tentative explanations for these findings, such as functioning prior to onset of psychosis, social support and relationship quality are explored.

CONCLUSION

Findings highlight the importance of this often-overlooked area in clinical practice. Studies with robust design, which specifically aim to understand the relationship between romantic relationships and wellbeing for people who experience psychosis are needed.

Internalized Stigma among Bedouin and Jews with Mental Illness: Comparing Self-Esteem, Hope, and Quality of Life

The aim of this study was to assess the differences in internalized-stigma, self-esteem, hope, and quality of life in individuals with mental illness from two diverse cultures (Bedouins and Jews) and to examine the relationships between self-stigma and self-esteem, hope, and quality of life in participants from both cultures. Two hundred participants with mental illness in Israel were assessed on the Internalized Stigma of Mental Illness (ISMI) scale. The Arab Bedouin participants tended to internalize stigma to a greater extent than the Jewish participants. Overall, there was a significant negative correlation between self-stigma, self-esteem, and hope and between alienation and quality of life in both groups although the correlation was stronger among the Arab Bedouin participants. By contrast, the associations between self-stigma and quality of life were only significant for two of the self-stigma dimensions (alienation and discrimination) among the Jewish participants. These results contribute to a better understanding of the role internalized stigma may play in the life of people with mental illness from diverse cultures. They may help design culturally appropriate intervention programs for people with mental illness.

Systematic review of global functioning and quality of life in people with psychotic disorders

AimsPeople with psychotic disorders face impairments in their global functioning and their quality of life (QoL). The relationship between the two outcomes has not been systematically investigated. Through a systematic review, we aim to explore the presence and extent of associations between global functioning and QoL and establish whether associations depend on the instruments employed.

METHODS

In May 2016, ten electronic databases were searched using a two-phase process to identify articles in which associations between global functioning and QoL were assessed. Basic descriptive data and correlation coefficients between global functioning and QoL instruments were extracted, with the strength of the correlation assessed according to the specifications of Cohen 1988. Results were reported with reference to the Meta-analysis of Observational Studies in Epidemiology guidelines and PRISMA standards. A narrative synthesis was performed due to heterogeneity in methodological approaches.

RESULTS

Of an initial 15 183 non-duplicate articles identified, 756 were deemed potentially relevant, with 40 studies encompassing 42 articles included. Fourteen instruments for measuring global functioning and 22 instruments for measuring QoL were used. Twenty-nine articles reported linear associations while 19 assessed QoL predictors. Correlations between overall scores varied in strength, primarily dependent on the QoL instrument employed, and whether QoL was objectively or subjectively assessed. Correlations observed for objective QoL measures were consistently larger than those observed for subjective measures, as were correlations for an interviewer than self-assessed QoL. When correlations were assessed by domains of QoL, the highest correlations were found for social domains of QoL, for which most correlations were moderate or higher. Global functioning consistently predicted overall QoL as did depressive and negative symptoms.

CONCLUSIONS

This review is the first to explore the extent of associations between global functioning and QoL in people with psychotic disorders. We consistently found a positive association between global functioning and QoL. The strength of the association was dependent on the QoL instrument employed. QoL domains strongly associated with global functioning were highlighted. The review illustrates the extensive array of instruments used for the assessment of QoL and to a lesser extent global functioning in people with psychotic disorders and provides a framework to understand the different findings reported in the literature. The findings can also inform the future choice of instruments by researchers and/or clinicians. The observed associations reassure that interventions for improving global functioning will have a positive impact on the QoL of people living with a psychotic disorder.

Correlation of Health-Related Quality of Life in Clinically Stable Outpatients with Schizophrenia

BACKGROUND

Generic health-related quality of life (HRQoL) scales are increasingly being used to assess the effects of new treatments in schizophrenia. The objective of this study is to better understand the usefulness of generic and condition specific HRQoL scales in schizophrenia by analyzing their correlates.

METHODS

Data formed part of the Pattern study, an international observational study among 1379 outpatients with schizophrenia. Patients were evaluated with the Mini International Neuropsychiatric Inventory, the Clinical Global Impression-Schizophrenia (CGI-SCH) Scale and the Positive and Negative Syndrome Scale (PANSS) and reported their HRQoL using the Schizophrenia Quality of Life Scale (SQLS), the Short Form-36 (SF-36), and the EuroQol-5 Dimension (EQ-5D). The two summary values of the SF-36 (the Mental Component Score and the Physical Component Score, SF-36 MCS and SF-36 PCS) were calculated.

RESULTS

Higher PANSS positive dimension ratings were associated with worse HRQoL for the SQLS, EQ-5D VAS, SF-36 MCS, and SF-36 PCS. Higher PANSS negative dimension ratings were associated with worse HRQoL for the EQ-5D VAS, SF-36 MCS, and SF-36 PCS, but not for the SQLS or the EQ-5D tariff. PANSS depression ratings were associated with lower HRQoL in all the scales. There was a high correlation between the HRQoL scales. However, in patients with more severe cognitive/disorganized PANSS symptoms, the SQLS score was relatively higher than the EQ-5D tariff and SF-36 PCS scores.

CONCLUSION

This study has shown substantial agreement between three HRQoL scales, being either generic or condition specific. This supports the use of generic HRQoL measures in schizophrenia.

Determinants of Health-Related Quality of Life in Schizophrenia: Beyond the Medical Model

Background: Improving Quality of Life (QoL) in Schizophrenia is an important treatment objective in the shift toward person-centered and recovery-oriented care. Health-Related Quality of Life (HRQoL) is a focused aspect of QoL that is directly impacted by healthcare intervention. This aim of the current study was to ascertain the clinical determinants of HRQoL in Schizophrenia and their collective contribution to HRQoL. Methods: 157 stable outpatients with schizophrenia were recruited for this study. Data collected included sociodemographic information and clinical characteristics. HRQoL was assessed on the RAND-36. Psychopathology was assessed on the Positive and Negative Syndrome Scale (PANSS) and functioning measured on the Global Assessment Scale (GAS). Findings: Multiple regression revealed that the Physical Health Component (PHC) of the RAND-36 was associated with positive symptoms (beta = -0.218, p = 0.005) and presence of psychiatric comorbidity (beta = -0.215, p = 0.003). The Mental Health Component (MHC) was associated with depressive (beta = -0.364, p < 0.001) and positive (beta = -0.175, p = 0.021,) symptoms. Symptoms, functioning, presence of psychiatric comorbidities, gender and age account for 20.3% of the total variance observed in HRQoL. Conclusion: Depressive and positive symptoms are key clinical determinants of HRQoL in people with schizophrenia. However, the medical model-looking solely at clinical determinants-could not account for a large proportion of variance in HRQoL. Hence, future research beyond the medical model is required to uncover the determinants of HRQoL in Schizophrenia. Identifying these factors will contribute toward developing a holistic and person-centered management plan for people with schizophrenia.

Patient Satisfaction and Quality of Life in People with Schizophrenia-Spectrum Disorders in a Rural Area

People suffering from schizophrenia-spectrum disorders often endorse a reduced quality of life (QoL) as compared to the general population. There appears to be a lack of studies for rural catchment areas for this patient population. We conducted a cross-sectional study with 94 people with schizophrenia-spectrum disorders in a mainly rural alpine area. We used multilevel models controlled for covariates to analyze the data. Total service satisfaction was associated with psychological aspects of subjective QoL and physical well-being in our model. Variables characterizing autonomy and empowerment of the person seem crucial concerning the QoL in this population.

Comorbid generalized anxiety disorder and its association with quality of life in patients with major depressive disorder

The comorbidity of major depressive disorder (MDD) and generalized anxiety disorder (GAD) is common and often predicts poorer outcomes than either disorder alone. This study aimed to examine the prevalence of comorbid GAD and its association with quality of life (QOL) among MDD patients. A total of 1225 psychiatric outpatients were screened using the Hospital Anxiety and Depression Scale (HADS). Those who scored ≥8 on the HADS were interviewed using DSM-IV criteria by two senior psychiatrists. Patients diagnosed with MDD were further assessed using the 9-item Patient Health Questionnaire, Social Support Rating Scale, Pittsburgh Sleep Quality Index, and World Health Organization QOL Scale, brief version (WHOQOL-BREF). Ultimately, 667 patients were diagnosed with MDD, of 71.7% of whom had GAD. Compared to those with MDD alone, comorbid patients had lower scores on the physical (38.64 ± 10.35 vs.36.54 ± 12.32, P = 0.026) and psychological (35.54 ± 12.98 vs. 30.61 ± 14.66, P < 0.001) domains of the WHOQOL-BREF. The association between comorbid GAD and poor QOL on the two domains remained statistically significant in the multiple linear regression (unstandardized coefficients: −1.97 and −4.65, P < 0.001). In conclusion, the prevalence of comorbid GAD in MDD patients is high, and co-occurring GAD may exacerbate impaired physical and psychological QOL in Chinese MDD patients.

Are Single-Item Global Ratings Useful for Assessing Health Status?

The research performance of the single-item self-rating In general, would you say your health is: excellent, very good, good, fair, or poor? was evaluated relative to the SF-36 General Health Scale that contains this item, using data for a sample of psychiatric outpatients who had co-occurring chronic physical conditions (N = 177). The scale was more robust than the single-item in cross-sectional validity tests and for predicting 2-year outcomes, but the single-item had stronger discriminant validity as a measure of physical health, especially in post-baseline analyses. Single-item and scale were both sensitive enough to detect change in perceived health over 2 years and a conditional experimental effect on health self-perceptions in a randomized trial. These findings demonstrate that a global single-item can be as valid, reliable, and sensitive as a multi-item scale for longitudinal research purposes, even if the scale performs better in cross-sectional surveys or as a screening measure.

The assessment of quality of life in clinical practice in patients with schizophrenia

The aim of the present article is to review QoL scales used in studies investigating patients with schizophrenia over the past 5 years, and to summarize the results of QoL assessment in clinical practice in these patients. Literature available from January 2009 to December 2013 was identified in a PubMed search using the key words "quality of life" and "schizophrenia" and in a cross-reference search for articles that were particularly relevant. A total of n=432 studies used 35 different standardized generic and specific QoL scales in patients with schizophrenia. Affective symptoms were major obstacles for QoL improvement in patients with schizophrenia. Though positive symptoms, negative symptoms, and cognitive functioning may be seen as largely independent parameters from subjective QoL, especially in cross-sectional trials, long-term studies confirmed a critical impact of early QoL improvement on long-term symptomatic and functional remission, as well as of early symptomatic response on long-term QoL. Results of the present review suggest that QoL is a valid and useful outcome criterion in patients with schizophrenia. As such, it should be consistently applied in clinical trials. Understanding the relationship between symptoms and functioning with QoL is important because interventions that focus on symptoms of psychosis or functioning alone may fail to improve subjective QoL to the same level. However, the lack of consensus on QoL scales hampers research on its predictive validity. Future research needs to find a consensus on the concept and measures of QoL and to test whether QoL predicts better outcomes with respect to remission and recovery under consideration of different treatment approaches in patients with schizophrenia.

Reliability and validity of the life functioning assessment inventory (L-FAI) for patients with psychosis

PURPOSE

Functioning level is one of the major indicators of recovery in schizophrenia. It is important that the assessment of functioning is performed accurately. However, functioning evaluation is difficult due to the absence of specific anchor points in the widely used functioning assessment scales. We aimed to validate a new functioning scale, the life functioning assessment inventory (L-FAI), which assesses the functioning outcome of patients with psychosis in a more objective, and comprehensive manner. L-FAI assesses four life domains including work, social relationships, leisure, and homemaking. Specific and concrete anchor points are set in each of these domains.

METHODS

The reliability and validity of L-FAI were assessed in 32 patients with psychosis. Opinions towards the scale were also obtained from experienced mental health professionals and members of a local advocacy group.

RESULTS

Good inter-rater reliability (Cohen's kappa 0.67-0.97) and test-retest reliability (Cohen's kappa 0.67-0.86) were found. The scale has also been found to have good concurrent validity, correlating well with social and occupational functioning assessment scale (SOFAS) and role functioning scale (RFS) (Spearman's r 0.53-0.89). The scale was associated solely with negative symptoms (Spearman's r -0.48) but not with positive symptoms.

CONCLUSIONS

L-FAI is suited for both clinical and research purposes in evaluating functioning level in patients with psychosis. More research is needed to replicate the current study with a larger sample size.

Predictive value of symptoms for quality of life in first-episode schizophrenia

BACKGROUND

Management of the disease symptomatology impacts the long-term functioning and quality of life (QOL) in psychotic patients.

AIM

The aim of this research was to study the association between psychiatric symptoms (positive, negative and general psychopathology symptoms) and QOL in first-episode schizophrenia patients.

METHODS

Fifty-five first-episode drug-naïve schizophrenia outpatients were recruited from a tertiary care hospital in New Delhi, India. WHOQOL-Bref (World Health Organization Quality of Life) Scale was used to assess multi-dimensional domains of QOL (physical, psychological, social and environmental health). The patients were evaluated clinically using PANSS and followed up for 6 months. Multivariate analyses were carried out to outline the symptoms which are predictive of QOL in these patients.

RESULTS

Physical well-being as assessed with WHOQOL-Bref is significantly impacted by the positive, negative and general psychopathology symptoms of the disease. General psychopathology symptoms demonstrated a strong relationship with different facets of QOL. These symptoms are predictive of physical (P=0.025) and psychological health (P=0.026), social relationships (P=0.009) and environmental QOL (P=0.022).

CONCLUSIONS

The general psychopathology symptoms significantly impact QOL in a diverse manner. Negative symptoms have a greater influence than positive symptoms on subjective QOL.

CLINICAL IMPLICATIONS

The antipsychotics focus on primary positive and negative disease symptoms. There is a need to develop a holistic approach (target non-psychotic symptoms intensively) in the disease management to prevent further long-term impairment of QOL.

Quality of life in obsessive-compulsive disorder: the role of mediating variables

This study examined the association of various clinical features of obsessive-compulsive disorder (OCD) with quality of life (QoL) in 102 adults with a principal diagnosis of OCD. Participants were assessed by trained clinicians using the Anxiety Disorders Interview Schedule 4th edition, the Yale-Brown Obsessive-Compulsive Scale, and an unstructured clinical interview. Subjects completed the MOS-36 Item Short Form Health Survey, and Beck Depression Inventory-II. Obsessive-compulsive symptom severity was negatively correlated with emotional health, social functioning and general health QoL. Depressive symptoms mediated the relationship between obsessive-compulsive symptom severity and emotional health, social functioning and general health QoL. Additionally, interference of obsessive-compulsive symptoms mediated the relationship between obsessive-compulsive symptom severity and emotional health, social functioning and general health QoL. Resistance against obsessive-compulsive symptoms mediated the relationship between obsessive-compulsive symptom severity and social functioning QoL. Diminished QoL is present in persons with OCD and is essential in understanding the complete clinical picture of OCD.

Health-related quality of life in patients with dual diagnosis: clinical correlates

Background

Although the studies published so far have found an affectation in the Health Related Quality of Life (HRQOL) in both psychiatric and substance use dependence disorders, very few studies have applied HRQOL as an assessment measure in patients suffering both comorbid conditions, or Dual Diagnosis. The aim of the current study was to assess HRQOL in a group of patients with Dual Diagnosis compared to two other non-comorbid groups and to determine what clinical factors are related to HRQOL.

Methods

Cross-sectional assessment of three experimental groups was made through the Short Form – 36 Item Health Survey (SF-36). The sample consisted of a group with Dual Diagnosis (DD; N = 35), one with Severe Mental Illness alone (SMI; N = 35) and another one with Substance Use Dependence alone (SUD; N = 35). The sample was composed only by males. To assess the clinical correlates of SF-36 HRQOL, lineal regression analyses were carried out.

Results

The DD group showed lower scores in most of the subscales, and in the mental health domain. The group with SUD showed in general a better state in the HRQOL while the group with SMI held an intermediate position with respect to the other two groups. Daily medication, suicidal attempts and daily number of coffees were significantly associated to HRQOL, especially in the DD group.

Conclusions

The DD group showed lower self-reported mental health quality of life. Assessment of HRQOL in dual patients allows to identify specific needs in this population, and may help to establish therapeutic goals to improve interventions.

Depression and Anxiety Following Psychosis: Associations with Mindfulness and Psychological Flexibility

Background: Individuals experiencing psychosis can present with elevated levels of depression and anxiety. Research suggests that aspects of depression and anxiety may serve an avoidant function by limiting the processing of more distressing material. Acceptance and Commitment Therapy suggests that avoidance of aversive mental experiences contributes to psychological inflexibility. Depression and anxiety occurring in the context of psychosis have a limiting effect on quality of life. No research to date has investigated how levels of psychological flexibility and mindfulness are associated with depression and anxiety occurring following psychosis. Aims: This study investigated associations psychological flexibility and mindfulness had with depression and anxiety following psychosis. Method: Thirty participants with psychosis were recruited by consecutive referral on the basis that they were experiencing emotional dysfunction following psychosis. The Hospital Anxiety and Depression Scale (HADS), Positive and Negative Syndrome Scale (PANSS), Acceptance and Action Questionnaire (AAQ-II) and the Kentucky Inventory of Mindfulness Skills (KIMS) were used. A cross-sectional correlational design was used. Results: The depression and anxiety subscales of the HADS both had significant correlations with psychological flexibility (as assessed by the AAQ-II) and aspects of mindfulness (as assessed by the KIMS). Hierarchical regression analyses indicated that psychological flexibility, but not mindfulness, contributed significantly to models predicting 46% of variance in both depression and anxiety scores. Conclusions: Although aspects of mindfulness are associated with depression and anxiety following an episode of psychosis, psychological flexibility appears to account for a larger proportion of variance in depression and anxiety scores in this population.

Subjective quality of life and suicidal behavior among Taiwanese schizophrenia patients

PURPOSE

Research of suicidal behavior in individuals with schizophrenia has often suggested that clinical characteristics and symptoms likely influence a patient's suicidal risk. However, there is a lack of research describing the link between patients' subjective quality of life (SQOL) and suicidal behavior in non-Western countries. Therefore, the current study attempts to explore how schizophrenia patients' SQOL and their suicidal behavior are related in a Taiwanese sample.

METHODS

In this study, 102 schizophrenia outpatients were investigated using the Taiwanese World Health Organization Quality of Life Schedule-Brief Version (WHO-QOL-BREF-TW), several Beck-Related symptom rating scales, and the Positive and Negative Syndrome Scale (PANSS) for psychopathology. These patients were also evaluated for suicidal risk using the critical items of the Scale for Suicide Ideation (SSI) and lifetime suicide attempts.

RESULTS

Statistical analyses, including independent sample t tests, analysis of covariance (ANCOVA) and logistic stepwise regression models were completed. Compared with the non-suicidal group, suicidal patients had significantly lower scores in SQOL domains. The differences in social domain remained significant after adjusting for depressive symptoms. In multiple logistic regression analyses, level of depressive and psychotic symptoms increased and poor social and psychological SQOL were significant contributors to suicidal behavior. Having removed depressive symptoms from the model, only dissatisfaction with social SQOL was associated with heightened suicidal risk.

CONCLUSIONS

Schizophrenia is associated with a high suicidal risk, of which depressive and psychotic symptoms are the major correlates. Again, the present study confirms and extends previous research showing that dissatisfied SQOL, particularly dissatisfaction with social relationships, should be considered in the assessment of suicidal risk in outpatients with schizophrenia, even when accounting other possible confounding factor such as depression.

Health-related quality of life and overall life satisfaction in people with serious mental illness

Quality of life (QoL) in people with schizophrenia and other serious mental illnesses (SMI) is an important outcome goal, yet there is no consistent definition of the construct. We examined three aspects of QoL in persons with SMI: overall life satisfaction, physical health-related QoL (HRQoL), and mental HRQoL. This study had two primary aims: first, to examine whether there are differences in physical and mental HRQoL in persons with SMI, and, second, to investigate the cognitive, clinical, and functional correlates of the three QoL indicators. Participants were 48 persons with SMI who completed assessments of QoL, cognition, functional capacity, psychiatric symptomatology, and medical comorbidity. Results indicate that participants experience similar levels of physical and mental HRQoL, and these two constructs are not related to one another. Physical HRQoL is associated with less medical comorbidity, while mental HRQoL is associated with negative and depressive symptoms. Overall life satisfaction was associated with fewer psychiatric symptoms and less medical comorbidity. This study adds to the important literature defining distinct domains of QoL and supports the necessity of addressing both physical and mental health factors as they relate to recovery and well-being among persons with SMI.

Evaluating depressive symptoms and their impact on outcome in schizophrenia applying the Calgary Depression Scale

OBJECTIVE

To examine depressive symptoms, their course during treatment, and influence on outcome.

METHOD

Weekly Calgary Depression Scale for Schizophrenia ratings were performed in 249 inpatients with schizophrenia. Early response was defined as a 20% reduction in the total score of the Positive and Negative Syndrome Scale for Schizophrenia from admission to week 2, response as a 50% reduction in the total score of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS) from admission to discharge and remission according to the consensus criteria.

RESULTS

Thirty six per cent of the patients were depressed at admission, with 23% of them still being depressed at discharge. Depressed patients scored significantly higher on the PANSS negative and general psychopathology subscore, featured more impairments in subjective well-being (P < 0.0001) and functioning (P < 0.0001). They suffered from more suicidality (P = 0.0021), and had greater insight into their illness (P = 0.0105). No significant differences were found regarding early response, response, and remission.

CONCLUSION

Patients with depressive symptoms should be monitored closely, given the burden of negative symptoms, their impairments in well-being and functioning and the threat of suicidality.

Quality of life of people with schizophrenia, bipolar disorder and other psychotic disorders

BACKGROUND

Health utility and quality of life (QoL) are increasingly important outcome measures in healthcare and health economics.

AIMS

To compare the loss of subjective QoL and utility-based health-related quality of life (HRQoL) associated with psychotic disorders.

METHOD

A representative sample of 8028 Finns was screened for psychotic disorders and bipolar I disorder. Lifetime psychotic disorders were diagnosed using the Structured Clinical Interview for DSM-IV and/or case records. Health-related quality of life was measured with EQ-5D and 15D, and QoL was measured with a 10-point scale.

RESULTS

Schizoaffective disorder was associated with the largest losses of QoL and HRQoL, with bipolar I disorder associated with similar or smaller losses than schizophrenia. Current depressive symptoms explained most of the losses.

CONCLUSIONS

Depressive symptoms are the strongest predictors of poor QoL/HRQoL in psychotic disorders. Subjective loss of QoL associated with psychotic disorders may be smaller than objective loss of functioning suggests. The EQ-5D is problematic as an outcome measure in psychotic disorders.

Correlates of quality of life in an Arab schizophrenia sample

OBJECTIVES

We focused on the subjective quality of life (QOL) indicators of the Lancashire quality of life profile, European version (LQoLP-EU) in a Kuwaiti schizophrenia sample. The objectives were: First, to assess the reliability and validity of the questionnaire. Second, to highlight the patients' QOL profile, in comparison with the results of the European five-nation study. Third, to examine the association of perceived needs for care, caregiver burden, service satisfaction, self-esteem and psychopathology, with three indices of global QOL: total life satisfaction or perceived QOL (PQOL) score; general wellbeing (GW) and Cantril's ladder (CL).

METHOD

Consecutive outpatients in stable condition and their family caregivers were interviewed with the LQoLP, and measures of needs for care, service satisfaction, caregiver burden and psychopathology.

RESULTS

There were 130 patients (66.1%m, mean age 36.8). Majority of the patients (56%) felt satisfied with the nine domains of life investigated, and 44.6% felt "averagely" happy. Their clinical severity was moderate (BPRS-18 = 44.4). In exploratory factor analysis (FA), the original domains were mostly replicated. Reliability indices were significant (>0.7). In stepwise regression analyses, the associations of PQOL were more in number and mostly different from those of GW and CL. The correlates of PQOL included, social unmet need (8.1% of variance), staff perception of unmet need (10.3%), general satisfaction with services (11.3%), burden of caregiver supervision (3.7%), self-esteem (2.9%) and positive symptoms (2.6%). Of the nine life domains, health was the most important correlate of GW and CL, indicating the centrality of health status in judgments of subjective QOL. In secondary FA, GW and CL loaded together, but separately from life domains, implying that these are separable parts of the subjective wellbeing construct.

CONCLUSION

The profile of QOL scores was mostly similar to European data. The significant multivariate association with patients/staff perceptions of unmet need for care and service satisfaction indicate the usefulness of staff professional development and service improvement in outcome; and imply that promotion of QOL should be an institutional objective. Our finding about the relationship between the three global measures of QOL has added support to the emerging QOL theory.

Antipsychotic medication, functional outcome and quality of life in schizophrenia: focus on amisulpride

BACKGROUND

Restoration of quality of life is considered as the ultimate treatment goal in the management of schizophrenia and is important for destigmatising the disease. However, few studies, including the most recent, have collected quality of life data prospectively or evaluated the relationship of treatment with quality of life.

SCOPE

Amisulpride is an atypical antipsychotic drug which has been described to have potency in improving negative symptoms of chronic schizophrenia and whose use is associated with a relatively low rate of emergence of extrapyramidal side-effects. These properties may contribute to a beneficial effect on quality of life. A systematic literature review of functional outcome in clinical trials with amisulpride was performed in order to assess the effect of this drug on quality of life and social functioning in patients. The Medline database was searched for all studies of amisulpride in schizophrenia which reported functional and quality of life outcomes up until 30 September 2009.

FINDINGS

Only one dedicated study assessing functional outcome or quality of life as a primary outcome criterion was identified. This demonstrated significant improvement in subjective well-being in patients with schizophrenia initiating treatment with amisulpride, and a correlation between this improvement and amelioration of psychopathology. In addition, functional outcome rating scales were used as secondary outcome measures in eight randomised clinical trials, and two naturalistic observational studies. Amisulpride treatment was associated with improvement in functional outcome, with effect sizes that were comparable between studies. Improvements in functional outcome are consistently greater than those observed in patients treated with haloperidol and similar in magnitude to those seen with three other atypical antipsychotics, namely olanzapine, ziprasidone and risperidone. A patient-reported outcome measure was used in only one comparative study, and demonstrated perception of a superior benefit with amisulpride compared to haloperidol. These findings could to some extent be replicated in several large naturalistic studies under standard conditions of care.

CONCLUSIONS

The data from studies on functional outcome and subjective well-being provide consistent information supporting the use of amisulpride for the treatment of schizophrenia in order to improve social functioning, integration into the community and autonomy, which are critical for the overall quality of life of patients with schizophrenia.

Better off in the community? A 5-year follow up study of long-term psychiatric patients discharged into the community

BACKGROUND

The quality of life of long-term psychiatric inpatients relocated to the community was investigated in this study. The aim was to investigate what changes, if any occurred, on standardised quality of life related instruments between discharge from hospital and at 1 year after discharge into the community. We were also interested to see if these changes continued 5 years after discharge into the community.

METHOD

87 long-stay psychiatric patients were enrolled in the study. Each patient was assessed on four standardised assessment instruments designed to assess their attitudes towards community living and level of functioning in the community.

RESULTS

Patients reported being satisfied in their new community environment. They showed improvements in their level of self-care and social functioning after 1 year in the community. These improvements were not maintained in their fifth year in the community. In addition, there were no improvements in patient's domestic skills, community skills or activity and social relations levels. Weekly occupation levels increased after 5 years in the community and their level of interests in things increased over the first year but not after 5 years in the community.

CONCLUSIONS

This study adds to the previous work carried out on patients discharged from large psychiatric hospitals into the community. Patients expressed a desire to continue to live in the community and while they showed improvements in self care and social functioning in the first year following discharge, these improvements were not sustained after 5 years in the community. Further training is needed for staff in the community residences so that patients can achieve their maximum potential.
