Subjective quality of life and its determinants in a catchment area based population of elderly schizophrenia patients

Comparison of subjective quality of life domains in schizophrenia, mood, and anxiety disorders; an individual patient data meta-analysis

This study sought to compare satisfaction with different subjective quality of life domains across individuals with three different mental health disorders. Samples from four separate studies were combined to conduct a one-step individual patient data meta-analysis. 5329 individuals with either a schizophrenia (n = 1839), mood (n = 1650), or anxiety disorder (n = 1840) were included. Mean satisfaction ratings for each life domain were compared across disorders. Associations between satisfaction ratings and personal characteristics were investigated using multivariable mixed effect models. Results showed that individuals with an anxiety disorder had the widest range of scores and reported lower satisfaction in most domains compared to those with a schizophrenia or mood disorder. Individuals with a schizophrenia disorder rated domains to do with 'others', such as relationships with family and sex life, as lower than individuals with a mood or anxiety disorder. Satisfaction ratings were often more impacted by personal characteristics, such as employment status, than by diagnostic category. These results demonstrate that specific life areas are impacted differently in the three mental health disorders studied. However, further research needs to consider the impact of personal characteristics across disorders, and the subjective quality of life in individuals with anxiety disorders in particular warrants further investigation.

Financial dissatisfaction in people with psychotic disorders - A short report on its prevalence and correlates in a large naturalistic psychosis cohort

Psychotic disorders have a strong negative impact on multiple aspects of daily life, including people's financial situation. This exploratory study examines the level of financial dissatisfaction and its correlates in a large cohort of people with psychotic disorders. Data from the first assessments of people with psychotic disorders (n = 5271) who were included in the Pharmacotherapy Monitoring and Outcome Survey (PHAMOUS; 2006-2020), which is conducted in the northern Netherlands, were used. The Manchester Short Assessment of Quality of Life (MANSA) was used to measure financial dissatisfaction. In addition, sociodemographic and psychiatric characteristics, substance use and global and social functioning were assessed. One-fifth to one-third of people with psychotic disorders report financial dissatisfaction, fluctuating over the year in which they were assessed. These proportions are considerably higher than in the general population. Cannabis and other substance use were associated with higher levels of financial dissatisfaction (small to medium effect). The other significant associations showed (very) small effect sizes. Therefore, we conclude that financial dissatisfaction in people with psychotic disorders appears to be relatively independent of other demographic and psychiatric characteristics, and global and social functioning. These findings are an important first step for increasing knowledge on financial dissatisfaction among people with psychotic disorders. The findings can also contribute to raising awareness about the topic for healthcare professionals working in this field.

The relationship between psychopathology, occupational balance, and quality of life among people with schizophrenia

OBJECTIVE

There is an increased risk of occupational imbalance and poor quality of life (QoL) if one has schizophrenia. Although evidence suggests a relationship between psychopathology and QoL, the association of occupational balance (OB) with QoL in schizophrenia is unclear. This study aimed to investigate the associations among psychopathology, occupational balance, and QoL in schizophrenia.

METHODS

This was a cross-sectional study carried out in a Community Mental Health Center (CMHC). Ninety-five individuals aged 18 years or older with the diagnosis of schizophrenia participated in the study. All participants completed a sociodemographic form, Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale in Schizophrenia (CDSS), Occupational Balance Questionnaire-11 Turkish Version (OBQ11-T), and the World Health Organisation Quality of Life Assessment Instrument (WHOQOL-100-TR). Relationships among clinical and depressive symptoms, OB, and QoL variables were examined through correlation analysis, and then multiple linear regression analysis was performed to determine the variables that have influences on QOL.

RESULTS

The study participants had low OB scores and the lowest mean in the WHOQOL-social relationships subscale. WHOQOL-overall QoL score demonstrated a moderate negative correlation with the PANSS-total score and PANSS-general psychopathology subscale score (r = -0.422, r = -0.463, P < 0.001) and a mild negative correlation with the CDSS-total score (r = -0.390, P < 0.001). OBQ11-T total score showed a moderate positive correlation with the WHOQOL-overall score (r = 0.549; P < 0.001). Findings from the multiple linear regression analysis revealed that OBQ11-T (β = -0.467, P = 0.000) and PANSS-general psychopathology (β = -0.221, P = 0.045) were significant predictors of the overall QoL, explaining 48% of the variance in the overall QoL (adjusted R²  = .43, P < 0.001).

CONCLUSION

Our study findings showed that OB and general psychopathology are determinants that should be considered in improving the QoL in individuals with schizophrenia. Thereby, addressing the symptoms of general psychopathology and occupational factors to improve the QoL may be achieved with the incorporation of occupation-based programmes to routine treatment. However, further research is required.

The puzzle of quality of life in schizophrenia: putting the pieces together with the FACE-SZ cohort

BACKGROUND

The determinants of quality of life (QoL) in schizophrenia are largely debated, mainly due to methodological discrepancies and divergence about the concepts concerned. As most studies have investigated bi- or tri-variate models, a multivariate model accounting for simultaneous potential mediations is necessary to have a comprehensive view of the determinants of QOL. We sought to estimate the associations between cognitive reserve, cognition, functioning, insight, depression, schizophrenic symptoms, and QoL in schizophrenia and their potential mediation relationships.

METHODS

We used structural equation modeling with mediation analyses to test a model based on existing literature in a sample of 776 patients with schizophrenia from the FondaMental Foundation FACE-SZ cohort.

RESULTS

Our model showed a good fit to the data. We found better functioning to be positively associated with a better QoL, whereas better cognition, better insight, higher levels of depression, and schizophrenic symptoms were associated with a lower QoL in our sample. Cognitive reserve is not directly linked to QoL, but indirectly in a negative manner via cognition. We confirm the negative relationship between cognition and subjective QoL which was previously evidenced by other studies; moreover, this relationship seems to be robust as it survived in our multivariate model. It was not explained by insight as some suggested, thus the mechanism at stake remains to be explained.

CONCLUSION

The pathways to subjective QoL in schizophrenia are complex and the determinants largely influence each other. Longitudinal studies are warranted to confirm these cross-sectional findings.

Prediction of quality of life in schizophrenia using machine learning models on data from Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial

While research focus remains mainly on psychotic symptoms, it is questionable whether we are placing enough emphasis on improving the quality of life (QoL) of schizophrenia patients. To date, the predictive power of QoL remained limited. Therefore, this study aimed to accurately predict the QoL within schizophrenia using supervised learning methods. The authors report findings from participants of a large randomized, double-blind clinical trial for schizophrenia treatment. Potential predictors of QoL included all available and non-redundant variables from the dataset. By optimizing parameters, three linear LASSO regressions were calculated (N = 697, 692, and 786), including 44, 47, and 41 variables, with adjusted R-squares ranging from 0.31 to 0.36. Best predictors included social and emotion-related symptoms, neurocognition (processing speed), education, female gender, treatment attitudes, and mental, emotional, and physical health. These results demonstrate that machine learning is an excellent predictive tool to process clinical data. It appears that the patient’s perception of their treatment has an important impact on patients’ QoL and that interventions should consider this aspect.

A comprehensive model of predictors of quality of life in older adults with schizophrenia: results from the CSA study

BACKGROUND

Numerous factors are known to influence quality of life of adults with schizophrenia. However, little is known regarding the potential predictors of quality of life in the increasing population of older adults with schizophrenia. The main objective of the present study was to propose a comprehensive model of quality of life in this specific population.

METHODS

Data were derived from the Cohort of individuals with Schizophrenia Aged 55 years or more (CSA) study, a large (N = 353) multicenter sample of older adults with schizophrenia or schizoaffective disorder recruited from French community mental-health teams. We used structural equation modeling to simultaneously examine the effects of six broad groups of clinical factors previously identified as potential predictors of quality of life in this population, including (1) severity of general psychopathology, (2) severity of depression, (3) severity of cognitive impairment, (4) psychotropic medications, (5) general medical conditions and (6) sociodemographic characteristics.

RESULTS

General psychopathology symptoms, and in particular negative and depressive symptoms, cognitive impairment, reduced overall functioning and low education were significantly and independently associated with diminished quality of life (all p < 0.05). Greater number of medical conditions and greater number of antipsychotics were also independently and negatively associated with quality of life, although these associations did not reach statistical significance in sensitivity analyses, possibly due to limited statistical power.

CONCLUSION

Several domains are implicated in quality of life among older adults with schizophrenia. Interventions targeting these factors may help improve importantly quality of life of this vulnerable population.

Outcome prediction with a social cognitive battery: a multicenter longitudinal study

The interest in social cognition in schizophrenia is justified by the relationship between deficits in these skills and negative functional outcomes. Although assessment batteries have already been described, there is no consensus about which measures are useful in predicting patient functioning or quality of life (QoL). We investigated a set of five measures of recognition of facial emotions, theory of mind (ToM), and empathy in a cohort of 143 patients with schizophrenia or schizoaffective disorder at inclusion and, amongst whom 79 were reassessed 1 year later. The distribution was satisfactory for the TREF (Facial Emotion Recognition Task), V-SIR (Versailles-Situational Intention Reading), and QCAE (Questionnaire of Cognitive and Affective Empathy). Internal consistency was satisfactory for the TREF, V-SIR, V-Comics (Versailles Intention Attribution Task), and QCAE. Sensitivity to change was acceptable for the TREF. The TREF and V-SIR showed a cross-sectional relationship with functioning beyond the clinical symptoms of schizophrenia but not beyond neurocognition. Moreover, the TREF and V-SIR at inclusion could not predict functioning one year later, whereas most neurocognitive and clinical dimensions at inclusion could. Finally, only affective QCAE showed a significant cross-sectional, but not longitudinal, association with QoL. In conclusion, the TREF had satisfactory psychometric properties and showed a cross-sectional, but not longitudinal, association with objective outcome measures, thus appearing to be reliable in clinical practice and research. The V-SIR also showed promising psychometric properties, despite a possible weakness to detect change. However, these measures should be interpreted within the context of the good predictive power of the neurocognitive and clinical status on the outcome.

Ageing with schizophrenia: an update

PURPOSE OF REVIEW

The aim of this review was to summarize the recent literature on the clinical symptoms, functioning, outcomes and treatments for older adults with chronic schizophrenia.

RECENT FINDINGS

The number and proportion of older adults with schizophrenia is rapidly increasing. Schizophrenia is a heterogeneous disorder and older adults with schizophrenia display significant variability in symptom severity, quality of life and overall outcomes. Many achieve stable disease remission, some display persistent nonremission and others experience fluctuating symptoms. Depression is commonly reported, and although rates of suicide are higher when compared with age-matched peers, the excess mortality seen in this population is mainly attributed to natural causes of death. Cognitive decline and reduced illness awareness have important implications for functional status and quality of life. Antipsychotics remain essential in the treatment regimen, although elderly patients with chronic disease may be good candidates for gradual dose reduction. Interdisciplinary treatment approaches as well as nonpharmacologic psychosocial interventions play a critical adjunctive role in the treatment of older adults with schizophrenia.

SUMMARY

Research focusing on schizophrenia in late life is sparse. Too often, older patients are eliminated from research studies or averaged in with all age groups. Thus, there continues to be gaps in our understanding of modifiable predictors of remission and recovery, and the most efficacious and safest treatment approaches for this age group.

Subjective health-related quality of life in community-dwelling middle-aged and older adults with early-onset schizophrenia

Background: Long-term outcome in schizophrenia remains unsatisfactory due to continued premature deaths and insufficient health treatment. Subjective quality of life (SQoL) measurements hold important information and have meaningful implications regarding ways of improving general health status. This study investigated the physical and mental SQoL and associated clinical and sociodemographic outcomes among community-dwelling middle-aged and older people with early-onset schizophrenia.Materials and methods: A cross-sectional interview study where participants residing in the Region of Southern Denmark were identified through The Danish Psychiatric Central Register. Of a total of 278 eligible individuals, 59 people aged 55-82 years old participated. The SQoL measure Medical Outcomes Short Form 36 version 2 (SF36) was used. Scores were compared by age groups with normative data for the Danish population. Associated outcomes were measured using Positive And Negative Symptom Scale Remission and others.Results: Increased mental SQoL was associated with schizophrenia in remission (adjusted B 9.43, p = .001), increased Mental Health Recovery Measure score (adjusted B 0.55, p < .001) and increased GAF score (adjusted B 0.32, p < .001). Comparing with Danish Normative data, mental SQoL was reduced (p = .001) among 55-64-year olds, but presented levels similar to the general population at ages over 65 years. Physical quality of life was similar to the general population.Conclusion: Over 65-year olds with schizophrenia seemed to have SQoL similar to their age peers in the general population. Aiming treatment at achieving state of remission or recovery would be an amenable measure toward increasing mental SQoL among middle-aged people with schizophrenia.

The Life Course Paradigm as a Lens for Holistic Nursing Research in Older Adults Diagnosed With Schizophrenia

Older adults diagnosed with schizophrenia (OADWS) have unique needs for care and live longer today than their forebears who were diagnosed with schizophrenia. As a result, nurses need to be prepared for the specific care of individuals who live with schizophrenia as they age. Together, Life Course Theory and holistic nursing suggest a good fit in the quest for successful solutions and/or outcomes for the unique problems that OADWS face. Holistic nursing views the patient as a whole person, considering all aspects of the patient’s experiences within life’s broader environment. The life course paradigm offers an effective way for nurses to understand issues that patients face throughout their lives, thus enhancing holistic nursing with a historical perspective. This is especially important for the care of OADWS, who face unique disparities as well as physical and psychological comorbidities over their life course. This article is intended to initiate a discussion of OADWS, focused with Life Course Theory as a holistic lens. Literature pertinent to the life course of OADWS is reviewed, followed by an analysis of the life course paradigm in relation to OADWS’ unique experiences. Conclusions support the holistic use of Life Course Theory in research and interventions for OADWS.

Excess medical comorbidity and mortality across the lifespan in schizophrenia.: A nationwide Danish register study

INTRODUCTION

People with severe mental illness have greater risk of un-detected and inadequately treated medical disorders, adding up to the risk of premature death. This study investigated how chronic medical comorbidity evolved across the lifespan in schizophrenia and the associated impact on mortality.

METHOD

A register-based retrospective nested case-control study was conducted, identifying incident cases of cardiovascular disease (CVD), chronic obstructive pulmonary disease (COPD), cancer and diabetes, as well as mortality due to these diseases, across the lifespan in schizophrenia.

SAMPLE

A schizophrenia cohort consisting of 4924 individuals aged 18-40 years registered with a diagnosis of schizophrenia (ICD-8: 295.0-3 + 295.9) during admission to a psychiatric hospital unit in 1970-79. Schizophrenia cases were age and gender matched with 22,597 controls in the general population.

RESULTS

Rate ratio (RR) of CVD and cancer were similar to controls. The RR of COPD and diabetes were increased across the lifespan. The probability of having been diagnosed prior to dying from CVD, cancer, pulmonary diseases or diabetes was markedly reduced in schizophrenia cases compared to controls. The RR of all-cause mortality and mortality from CVD, COPD and diabetes remained elevated in all age groups in schizophrenia. Registration of medical comorbidity was associated with increased survival.

CONCLUSION

Excess medical comorbidity persists across the lifespan and into older age. No age-related decrease in incidence of major chronic medical comorbidities in schizophrenia was found except for diabetes.

Determinants of quality of life among people diagnosed with schizophrenia at outpatient clinics

PURPOSE

The study examines the determinants of the quality of life (QoL) among outpatients with schizophrenia in Jordan.

DESIGN AND METHODS

A cross-sectional study design was used with 157 people with schizophrenia treated in outpatient clinics. Demographic, clinical and psychosocial variables were examined for their influence on QoL. Data were analysed with descriptive statistics, Pearson product moment correlation and stepwise forward multiple linear regression.

FINDINGS

The majority of the study participants were female, single, unemployed, had secondary level of education or less and were being supported financially by family members. QoL correlated negatively with advanced age, male gender, longer duration of illness, high body mass index and prescribed typical anti-psychotic medication. However, it was correlated positively with employment and being married. Illness duration, recurrent hospitalisation, knowledge level about schizophrenia, psychiatric symptoms and coping mechanisms were found to be key significant predictors of QoL among participants.

PRACTICAL IMPLICATIONS

The study findings enhance our understanding of socio-demographic, clinical and psychosocial characteristics influencing the QoL in people with schizophrenia. Involvement of families in the management process may improve patients' ability to be integrated in the community and be more socially active.

The correlation between the quality of life and clinical variables among outpatients with schizophrenia

The study identifies the correlation between the quality of life (QoL) among outpatients with schizophrenia and clinical outcomes. A cross-sectional study design was used with 157 people with schizophrenia treated in outpatient clinics. Demographic, clinical and psychosocial variables were examined for their influence on QoL. Data were analysed with descriptive statistics, Pearson product moment correlation and stepwise forward multiple linear regression. The majority of the study participants were female, single, unemployed, had secondary level of education or less and were being supported financially by family members. QoL correlated negatively with advanced age, male gender, longer duration of illness, high body mass index and prescribed typical anti-psychotic medication. However, it was related positively with employment and being married. Illness duration, recurrent hospitalisation, knowledge level about schizophrenia, psychiatric symptoms and coping mechanisms were found to be key significant predictors of QoL among participants. The study findings enhance our understanding of socio-demographic, clinical and psychosocial characteristics influencing the QoL in people with schizophrenia. Involvement of families in the management process may improve patients' ability to be integrated in the community and be more socially active.

Negative symptoms, anxiety, and depression as mechanisms of change of a 12-month trial of assertive community treatment as part of integrated care in patients with first- and multi-episode schizophrenia spectrum disorders (ACCESS I trial)

Assertive community treatment (ACT) has shown to be effective in improving both functional deficits and quality of life (QoL) in patients with severe mental illness. However, the mechanisms of this beneficial effect remained unclear. We examined mechanisms of change by testing potential mediators including two subdomains of negative symptoms, i.e. social amotivation as well as expressive negative symptoms, anxiety, and depression within a therapeutic ACT model (ACCESS I trial) in a sample of 120 first- and multi-episode patients with a schizophrenia spectrum disorder (DSM-IV). Path modelling served to test the postulated relationship between the respective treatment condition, i.e. 12-month ACT as part of integrated care versus standard care, and changes in functioning and QoL. The final path model resulted in 3 differential pathways that were all significant. Treatment-induced changes in social amotivation served as a starting point for all pathways, and had a direct beneficial effect on functioning and an additional indirect effect on it through changes in anxiety. Expressive negative symptoms were not related to functioning but served as a mediator between changes in social amotivation and depressive symptoms, which subsequently resulted in improvements in QoL. Our results suggest that social amotivation, expressive negative symptoms, depression, and anxiety functioned as mechanisms of change of ACCESS. An integrated and sequential treatment focusing on these mediators may optimise the generalisation effects on functioning as well as on QoL by targeting the most powerful mechanism of change that fits best to the individual patient.

"Like Every Normal Person?!" The Paradoxical Effect of Aging With Schizophrenia

Studies on aging with schizophrenia have focused mainly on the adversities of aging with mental illness. The present study, however, examined the subjective experience of well-being among individuals with schizophrenia. Taking a phenomenological reflective life-world approach, in-depth, semistructured interviews with 18 aging individuals with schizophrenia were thematically analyzed. Four main themes emerged: (a) "I love the pills . . . they are very helpful": A balanced course of the illness as a basis for well-being in old age; (b) "I'm going to have my own exhibition at the museum": Self-fulfillment as promoting well-being; (c) "It's just like a family here": Experiencing a sense of belonging; and (d) "I live like everyone else": Aging as an opportunity for normalization. Alongside hardship, the participants perceived old age as a "window of opportunity," enabling the fulfillment of lifelong desires for a social life, acceptance, and a satisfying occupation. Implications regarding interventions with this unique population are discussed.

Quality of life in schizophrenic patients: the influence of sociodemographic and clinical characteristics and satisfaction with social support

Abstract Objective To evaluate the relationship of sociodemographic and clinical characteristics and satisfaction with social support with the quality of life of schizophrenic patients. Methodology This study included a sample of 268 participants. An interview was conducted to obtain sociodemographic and clinical data, supplemented with two assessment tools used to evaluate quality of life (World Health Organization Quality of Life instrument-Abbreviated version – WHOQOL-Bref) and satisfaction with social support (Social Support Satisfaction Scale – SSSS). Descriptive and inferential analyses were performed. Results Most individuals were male (63.4%), with a mean age of 45.4 years, single (85.4%), living with their family (62.3%) and unemployed (90.3%). As for clinical characteristics, most had the disease for less than 20 years (50.7%), and 55.6% had at least one hospitalization within the last 5 years. Being employed and having had no hospitalization within the last 5 years were positively correlated with one or more WHOQOL-Bref domains. The results of the variables intimacy (p<0.001) and satisfaction with friends (p<0.001) were independently related to the total WHOQOL-Bref score. Conclusion Having a job, having had no hospitalization within the last 5 years and having greater satisfaction with social support are factors that positively influence quality of life among schizophrenics. It is therefore crucial that the psychosocial rehabilitation of patients with schizophrenia take these factors into account, increasing the support network, preventing relapses and promoting occupational activities.

Advances in the Conceptualization and Study of Schizophrenia in Later Life

A crisis looms as research and clinical programs have not kept pace with dramatic increases in the number of older adults with schizophrenia. This article provides an overview of the advances in the conceptualization and study of schizophrenia in later life. Theoretic and clinical models in psychiatry and gerontology are integrated. Specifically, recovery is examined in the context of aging, how clinical dimensionality affects diagnoses in older adults, how various features of schizophrenia are implicated in models of accelerated and paradoxic aging, and how outcome in later life is a more dynamic and heterogeneous than assumed previously.

Associations between social vulnerabilities and psychosocial problems in European children. Results from the IDEFICS study

The effect of socioeconomic inequalities on children's mental health remains unclear. This study aims to explore the cross-sectional and longitudinal associations between social vulnerabilities and psychosocial problems, and the association between accumulation of vulnerabilities and psychosocial problems. 5987 children aged 2-9 years from eight European countries were assessed at baseline and 2-year follow-up. Two different instruments were employed to assess children's psychosocial problems: the KINDL (Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents) was used to evaluate children's well-being and the Strengths and Difficulties Questionnaire (SDQ) was used to evaluate children's internalising problems. Vulnerable groups were defined as follows: children whose parents had minimal social networks, children from non-traditional families, children of migrant origin or children with unemployed parents. Logistic mixed-effects models were used to assess the associations between social vulnerabilities and psychosocial problems. After adjusting for classical socioeconomic and lifestyle indicators, children whose parents had minimal social networks were at greater risk of presenting internalising problems at baseline and follow-up (OR 1.53, 99% CI 1.11-2.11). The highest risk for psychosocial problems was found in children whose status changed from traditional families at T0 to non-traditional families at T1 (OR 1.60, 99% CI 1.07-2.39) and whose parents had minimal social networks at both time points (OR 1.97, 99% CI 1.26-3.08). Children with one or more vulnerabilities accumulated were at a higher risk of developing psychosocial problems at baseline and follow-up. Therefore, policy makers should implement measures to strengthen the social support for parents with a minimal social network.

A Longitudinal Analysis of Quality of Life and Associated Factors in Older Adults with Schizophrenia Spectrum Disorder

OBJECTIVES

Self-perceived quality of life (QOL) is an important outcome indicator in schizophrenia and a predictor of symptomatic and functional improvement. This study provides the first large scale longitudinal study of the fluctuations, predictors, and impact of QOL in older adults with schizophrenia spectrum disorder (SSD).

METHODS

The sample consisted of 104 community-dwelling persons with SSD aged 55 and over (mean age: 61years) who developed the disorder prior to age 45. Mean follow-up was 52.5 months (range 12-116 months); 55% were men; 55% were white. We identified 22 potential predictor variables and used the Quality of Life Index (QLI) to assess QOL.

RESULTS

There were no significant group differences in the QLI at baseline and follow-up. However, 33%, 24% and 43% of persons exhibited > 0.5 effect size increase or decrease, or no change, respectively. In multivariable analysis, there were 5 baseline predictors of QLI at follow-up: QLI, Center for Epidemiological Studies-Depression Scale (CES-D) scores, religiousness, perceived well-being versus others/past self, and time from initial interview. Baseline QLI predicted 5 variables at follow-up: the Positive and Negative Syndrome Scale (PANSS) anxiety score, PANSS positive score, CES-D score, insight, and perceived well-being versus others/past self.

CONCLUSION

In many persons with SSD, QOL is not static in later life and one third improved their QOL. Effectively treating depressive symptoms and encouraging religious participation may improve QOL. QOL had two pivotal roles: As a relatively independent dynamic outcome measure and as a critical variable affecting clinical outcomes such as anxiety, depressive and positive symptoms.

Childhood trauma, depression and negative symptoms are independently associated with impaired quality of life in schizophrenia. Results from the national FACE-SZ cohort

OBJECTIVES

Depression and negative symptoms have been associated with impaired Quality of life (QoL) in schizophrenia (SZ). However, childhood trauma may influence both QoL and depression in SZ patients, with consequences for the management of impaired QoL in SZ patients. The aim of the present study was to determine if childhood trauma was associated with impaired QoL in schizophrenia.

METHOD

A sample of 544 community-dwelling stabilized SZ patients enrolled in FACE-SZ cohort were utilized in this study (74.1% males, mean aged 32.3years, mean illness duration 10.6years). QoL was self-reported with the S-QoL18 questionnaire. Childhood trauma was self-reported with the Childhood Trauma Questionnaire. Depression was measured by the Calgary Depression Rating Scale for Schizophrenia. Psychotic severity was measured by the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). Other clinical factors, treatments, comorbidities, functioning and sociodemographical variables were also recorded, with validated scales.

RESULTS

Overall, 151 participants (27.8%) had a current major depressive episode and 406 (82.5%) reported at least one episode of historical childhood trauma. In multivariate analyses, lower QoL total score was associated with a history of childhood trauma (β=-0.21, p<0.0001), psychotic negative symptoms (β=-0.11, p=0.04), current depression (β=-0.0.38, p<0.0001) and male gender (β=-0.16, p<0.0001).

CONCLUSION

Impaired QoL is independently associated with negative symptoms, depression and childhood trauma in schizophrenia.

Caregiver's quality of life and its positive impact on symptomatology and quality of life of patients with schizophrenia

Background

Although the quality of life (QoL) experienced by patients with schizophrenia has been recognized, few studies have assessed the relationship between the caregivers’ QoL and patients’ QoL.

Methods

The study included 253 stabilized outpatients with schizophrenia and their caregivers from 3 Mental Health Services in Bolivia (N = 83), Chile (N = 85) and Peru (N = 85). Caregivers’ and patients’ QoL were respectively assessed using two specific QoL questionnaires (S-CGQoL and S-QoL 18). We collected socio-demographic information and clinical data. Multiple linear regressions were performed to determine which variables were associated with patient’s QoL. We tested the following hypothesis using structural equation modeling (SEM): caregivers’ QoL may have an indirect effect on patients’ QoL mediated by their influence of the severity of psychotic symptoms.

Results

In the multivariate analysis, the caregivers’ QoL was not significantly associated with the patients’ QoL, except for one QoL dimension about relationship with family (Beta = 0.23). Among patients’ characteristics, being a woman and Aymara, having lower educational level, unemployment and severity of symptoms was significantly associated to a lower QoL. The SEM revealed a moderate significant association between caregivers’ QoL and psychotic symptoms severity (path coefficient = −0.32) and a significant association between psychotic symptoms severity and patients QoL (path coefficient = −0.40). The indirect effect of caregivers’ QoL on patients’ QoL was significant (mediated effect coefficient = 0.13).

Conclusion

Improvement of caregiver’s QoL may have a direct impact on the psychotic symptoms of patients and indirectly on patient’s QoL, confirming the need for ongoing family interventions in these regions.

The Correlates of Quality of Life Among Jordanian Patients With Schizophrenia

BACKGROUND

Addressing the quality of life (QOL) of patients with schizophrenia is of special importance in the Arab world, where little knowledge is available about their well-being, and most of them experience stigma and living in poverty.

AIMS

The purpose of this study was to examine the association of sociodemographic characteristics, severity of depressive symptoms, and various aspects of public stigma against mental illness, with QOL among Jordanian patients with schizophrenia.

METHOD

In this descriptive correlational study, 160 Jordanian outpatients diagnosed with schizophrenia completed measures of demographic characteristics, perceived public stigma against mental illness, severity of depression, and QOL.

RESULTS

Participants had poor QOL. Age, marital status, relapse, education level, stigma against mental illness, and severity of depression were significantly associated with QOL among Jordanian patients with schizophrenia. Data analysis revealed that the severity of depression accounted for an additional 27% of the variance above and beyond the 36.7% accounted for by age of the participants and perceived public stigma against mental illness.

CONCLUSIONS

Health care professionals should develop culturally competent nursing practice considering the specific factors associated with QOL among Arab patients with schizophrenia.

A structural equation modelling approach to explore the determinants of quality of life in schizophrenia

OBJECTIVE

This study aimed to analyse the relationships among psychotic symptoms, depression, neurocognition and functioning as determinants of quality of life (QoL) in patients with schizophrenia.

METHODS

In this cross-sectional study, we evaluated QoL with the Schizophrenia Quality of Life 18-item scale (S-QoL 18), neurocognition with multiple tests exploring memory, attention and executive functions, the severity of psychotic symptoms with the Positive and Negative Syndrome Scale (PANSS), depression with the Calgary Depression Scale for Schizophrenia (CDSS) and functioning using the Functional Remission Of General Schizophrenia (FROGS) scale. We used Structural Equation Modelling (SEM) to describe the relationships among the severity of psychotic symptoms, depression, neurocognition, functioning and QoL.

RESULTS

Two hundred and seventy-one outpatients with schizophrenia participated in our study. SEM showed good fit with χ(2)/df=1.97, root mean square error of approximation=0.06, comparative fit index=0.93 and standardized root mean square residuals=0.05. This model revealed that depression was the most important feature associated with QoL, mainly for the self-esteem, autonomy and resilience dimensions (direct path coefficient=-0.46). The direct path between functioning and QoL was also significant (path coefficient=0.26). The severity of psychotic symptoms and neurocognitive impairment were weakly and indirectly associated with QoL via functioning (path coefficients=-0.18 and 0.04, respectively).

CONCLUSIONS

This study contributes to a better understanding of the determinants of QoL in schizophrenia. Our findings should be considered in developing effective strategies for improving QoL among this population.

Esquizofrenia refratária: qualidade de vida e fatores associados

Resumo Objetivo Analisar a qualidade de vida de pessoas com esquizofrenia refratária em uso de clozapina e seus fatores associados. Métodos Estudo de delineamento transversal, realizado na Região Ampliada Oeste de Minas Gerais, que incluiu pacientes com esquizofrenia refratária em uso do antipsicótico clozapina. Para a mensuração da qualidade de vida, foi utilizada a escala Quality of Life Scale, específica para pacientes com esquizofrenia. Foram realizadas análise univariada e multivariada. Resultados Participaram 72 pacientes, com média de idade de 42,9 anos. O escore global da Quality of Life Scale indicou qualidade de vida comprometida, com maior prejuízo no domínio rede social (mediana = 2,36). A análise de regressão logística apontou fatores associados a uma melhor qualidade de vida. Conclusão Evidenciou-se uma baixa qualidade de vida dos pacientes com esquizofrenia refratária. Praticar atividade física, renda familiar acima de três salários mínimos e possuir filhos foram associados à melhor qualidade de vida.

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.

Utility decrements associated with side effects in schizophrenia

OBJECTIVE

Most of the existing studies investigating the impact of schizophrenia on utility have focused on the different stages of the disease. The objective of this study was to describe and quantify the impact of treatment-related side-effects on utility in patients with schizophrenia, using data from an observational study.

METHODS

This study used data from the European Schizophrenia Cohort (EuroSC), a multi-center 2-year cohort study conducted in France, England, and Germany. The EQ-5D questionnaire was completed every 6 months, as well as the Subjective Side Effect Rating Scale, assessing patient distress over extrapyramidal symptoms (EPS), weight gain, sedation, and sexual dysfunction, used to assess whether or not the patient experienced the side-effect. At first a bivariate analysis was conducted to describe utility values with and without side-effects. Then, a random effects regression analysis was performed on utility, where random effects were controlled for repeated measures on the same subjects, with potential confounding factors. Finally, findings were compared with those of previous publications.

RESULTS

This sample consisted of 1208 patients with schizophrenia. At the baseline visit, the most reported side-effect was EPS (almost 60% of patients), followed by sedation and weight gain (∼50% of patients for each), and sexual dysfunction (almost 30% of patients). Significant association with severity of symptoms, functioning abilities, and utility were found. Patients reporting none of the studied side-effects had an average EQ-5D index score of 0.81, found to be higher than scores of patients reporting EPS (0.70), sexual dysfunction (0.67), sedation (0.70), or weight gain (0.72). The random effects model reported a utility decrement of 0.042 for EPS, 0.022 for weight gain, 0.022 for sexual dysfunction, and 0.019 for sedation. Although the external validation was difficult due to the different methods or definitions of the side-effects, as well as the paucity of data for weight gain, sedation and sexual dysfunction, the results were generally consistent with previous studies.

CONCLUSION

This study aimed at quantifying the direct impact of main side-effects associated with antipsychotics on patients' utility. RESULTS suggested a significant direct impact of side-effects, with EPS being the most impactful.
