Impact of sociodemographic and clinical factors on subjective quality of life in schizophrenia patients in Beijing, China

The impact of sociodemographic and clinical factors on subjective quality of life (SQOL) in Chinese schizophrenia outpatients was explored. Randomly selected subjects with schizophrenia (N = 273) were assessed with respect to their sociodemographic, clinical characteristics, and SQOL. Compared with the Chinese general population, patients had significantly lower scores in the physical and social SQOL domains. Multiple regression analyses revealed that depressive symptoms inversely predicted all SQOL domains; positive symptoms negatively predicted psychological, social, and environmental SQOL domains whereas educational level, extrapyramidal side effects, anxiety, history of suicide attempts, employment status, monthly income, number of hospitalization, and length of illness all significantly contributed to 1 or 2 SQOL domains.     

Subjective quality of life of Nigerian schizophrenia patients: sociodemographic and clinical correlates

Objective: Subjective quality of life (QOL) is dependent upon culture and its evaluation based on one’s particular belief system. This study aimed to examine the subjective QOL of Nigerian out‐patients with schizophrenia and its correlates. Method: Out‐patients with Schizophrenia (n = 99) completed the WHOQOL‐BREF as a measure of their subjective QOL. Sociodemographic, illness related and medication related details were also obtained. Results: Overall, 21 patients (21.2%) were categorised as having ‘good’ and 36 (36.4%) as having ‘poor’ subjective QOL. ‘Poor’ subjective QOL correlated with anxiety/depression symptoms (OR 4.88, 95% CI 2.93–11.48), comorbid medical problems (OR 4.75, 95% CI 1.43–16.33), unemployment (OR 3.75, 95% CI 1.25–11.72) and poor social support (OR 4.60, 95% CI 1.49–14.28). Conclusion: Efforts to improve the QOL of patients with schizophrenia in this environment should encompass the identified variables. Larger, longitudinal and multi‐centred studies are needed to adequately identify factors predicting QOL in this environment.     

Social cognition and quality of life in schizophrenia

Schizophrenia is associated with poor quality of life (QOL). Whereas the effects of neurocognitive deficits and psychopathology on QOL of schizophrenia patients have recently been elucidated, little is known about social cognitive deficits in this regard. This study investigated the influence of social cognition on QOL in schizophrenia. A sample of 1032 patients, 1011 of their siblings, and 552 healthy controls was recruited from the Dutch Genetic Risk and Outcome in Psychosis (GROUP) study. Participants completed a battery of cognitive tests, including social cognitive tests on theory of mind and emotion perception. To assess QOL the World Health Organization QOL Assessment-BREF (WHOQOL-BREF) was used. Schizophrenia symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Social cognitive performance was significantly worse in patients compared to siblings and healthy controls. Patients had the poorest QOL, while QOL in healthy controls was better than in siblings. Theory of mind but not emotion perception or neurocognition was associated with QOL in patients, whereas neurocognition was the only significant predictor of QOL in siblings and healthy controls. There was a significant interaction between theory of mind and symptom severity with respect to QOL. Our study indicates that social cognition is associated with QOL in schizophrenia. Theory of mind rather than emotion perception is associated with QOL, and this association is moderated by schizophrenia symptoms. In particular, patients with relatively unimpaired theory of mind and more severe schizophrenia symptoms have poor QOL and could therefore benefit from therapeutic intervention.     

The relationship between cognitive insight, clinical insight, and depression in patients with schizophrenia

Despite comorbid depression being relatively common even in subjects with schizophrenia, to the best of our knowledge, there is, to date, no report in the literature specifically and detailed examining the cognitive and clinical insight in subjects with schizophrenia and a comorbid depressive syndrome. Hence, in this study, we sought to compare the cognitive and clinical insight in our subjects with schizophrenia with and without a comorbid depressive syndrome. We found that participants in the depressive group scored significantly higher on self-reflectiveness and the reflectiveness-certainty (R-C) index scores than those in the nondepressive group. There was no significant difference among groups on the Scale for the Assessment of Positive Symptoms, Scale for the Assessment of Negative Symptoms, and clinical insight scores assessed by the Scale to Assess Unawareness of Mental Disorder. In addition, self-reflectiveness scores significantly correlated with depression, observed depression, hopelessness, and suicidality subscores of the Calgary Depression Scale for Schizophrenia. A better understanding of the cognitive component of insight in schizophrenia with comorbid depression may contribute to develop more efficient cognitive strategies, thus improving patient outcome. However, clinicians should be aware of the possibility of exacerbating a sense of hopelessness and suicide risk during the interventions that improve cognitive insight.     

The impact of comorbidity and other clinical and sociodemographic factors on health-related quality of life in Greek patients with Parkinson's disease

Objectives: This study was designed to evaluate the impact of other common self-reported comorbid disorders (hypertension, dyslipidemia, ischemic heart disease, diabetes mellitus, minor stroke, arthritis, low back pain or osteoporosis and depression) on health-related Quality of Life (HRQoL) of Parkinson's disease (PD) patients and to explore the association of their HRQoL with various sociodemographic and clinical factors.

Methods: Data about age, gender, education, occupation, income, marital and residential status, social relations, disease duration, functional status, treatment and concomitant diseases were collected of 139 Greek patients (68 men and 71 women) with PD. Patients were consecutively recruited from the outpatient clinic of the first Neurology Department of Athens National University at Aeginition Hospital. Disease severity was assessed using the unified Parkinson's disease rating scale including Hoehn and Yahr and Schwab and England (S&;E) scales. HRQoL was measured by the specific Parkinson's disease questionnaire (PDQ-39). A multivariate multiple regression model with normal errors was used for the statistical analysis.

Results: The main determinants of HRQoL were low degree of independence measured by the S&;E scale (F?=?35.942, p?F?=?20.508, p?F?=?14.983, p?F?=?6.507, p?=?0.013) and gastrointestinal disturbances (F?=?4.643, p?=?0.035) and the presence of depression (F?=?6.022, p?=?0.017).

Conclusion: Among the other chronic comorbidities only depression was associated with a poor HRQoL in PD patients. Functional dependence and social isolation contributed most to worse HRQoL. Our findings suggest that adequate social support and management of depression, sleep and gastrointestinal disturbances could reduce the distress and improve HRQoL in patients with PD.     

Associated factors of quality of life in first-episode schizophrenia patients

Objective

Improving quality of life is an important goal in the treatment of schizophrenia. In previous research, quality of life has been reported to be compromised in patients with schizophrenia. The aim of this study was to investigate whether quality of life may be impaired in first-episode schizophrenia patients and to identify the associated factors of quality of life in first-episode schizophrenia.

Methods

Forty-eight patients with first-episode schizophrenia and 20 normal controls were recruited. Quality of life was measured by using the Quality of Life scale (QLS). General and social self-efficacy, perceived social support were measured by using the self-report scales. The clinical assessments and comprehensive neurocognitive battery were also administered.

Results

First-episode group showed significantly decreased QLS total and QLS subscale scores compared to normal controls group. The key associated factors of quality of life in patients with first-episode schizophrenia were the negative symptoms and social self-efficacy.

Conclusion

This finding implies that compromised quality of life may be already emerged in schizophrenia in their first-episode and the psychosocial interventions should be targeting the negative symptoms and the psychosocial protective factors including self-efficacy in addition to simply ameliorating the positive symptoms to foster social reintegration and recovery of first-episode patients.     

Quality of life of Chinese schizophrenia outpatients in Hong Kong: relationship to sociodemographic factors and symptomatology

OBJECTIVE: To explore the relationships between sociodemographic and clinical factors and quality of life (QOL) in a cohort of Chinese schizophrenia outpatients. METHOD: Two hundred subjects with a diagnosis of DSM-IV schizophrenia aged 18-60 years were randomly selected, and their sociodemographic and clinical characteristics including psychotic and depressive symptoms, extrapyramidal symptoms (EPS), and quality of life were assessed. Correlation and multiple regression analyses were used to evaluate the relationships of sociodemographic, clinical data and QOL. RESULTS: Compared to normative data obtained for the general population in Hong Kong, significantly lower scores in physical, psychological, and social QOL domains were found in the patient group. History of suicidal attempts and the presence of positive, negative, depressive, anxiety and EPS symptoms were all significantly correlated with QOL in schizophrenia patients. After controlling for the effects of variables that were significantly correlated with QOL in the correlation analysis, however, only depressive symptoms were still significantly correlated with each QOL domain. Multiple regression analysis showed that depressive symptoms predicted all QOL domains, while positive symptoms predicted overall and physical QOL domains. CONCLUSIONS: Chinese outpatients with schizophrenia had poorer QOL than the general population. In this patient population, QOL was more strongly related to the severity of depressive symptoms and was independent of sociodemographic factors.     

Quality of life in schizophrenia: relationship to sociodemographic factors,symptomatology and tardive dyskinesia

The influence of sociodemographic, clinical and treatment factors on the quality of life of patients with schizophrenia has yet to be fully defined. We evaluated the quality of life of patients with schizophrenia who were attending a catchment area rehabilitation centre, in order to establish its clinical correlates. These patients had a poor to moderate quality of life which was inversely related to negative symptom severity, illness duration, the cumulative length of previous hospitalization and patient age. Patients residing in hostels or group homes had a poorer quality of life than those living independently or with their family. The presence of tardive dyskinesia was associated with a poorer quality of life. This association merits further invesigation.     

Spiritual/religious coping in patients with epilepsy: Relationship with sociodemographic and clinical aspects and quality of life

The relationship between headache and seizures is a complicated one, since these two conditions are related in numerous ways.Although the nature of this association is unclear, several plausible explanations exist: the two disorders coexist by chance; headache is part (or even the sole ictal phenomenon) of seizures or the post-ictal state; both disorders share a common underlying etiology; and epilepsy mimics the symptoms of migraine (as in benign childhood epilepsy).Seizures and headaches as well as their respective primary syndromes (epilepsy and headache/migraine) share several pathophysiological mechanisms. These mechanisms especially involve neurotransmitter and ion channel dysfunctions. Also, photosensitivity seems to play a role in the connection. In order to improve the care for patients with a clinical connection between migraine and epilepsy, it is necessary to try to understand more accurately the exact pathophysiological point of connection between these two conditions. Both experimental and clinical measures are required to better understand this relationship. The development of animal models, molecular studies defining more precise genotype/phenotype correlations, and multicenter clinical studies with revision of clinical criteria for headache/epilepsy-related disorders represent the start for planning future translational research.In this paper, we review the relationship between migraine and epilepsy in terms of epidemiology and pathophysiology with regard to translational research and clinical correlations and classification.This article is part of a Special Issue entitled “The Future of Translational Epilepsy Research”.     

Sexual functioning, psychopathology and quality of life in patients with schizophrenia

OBJECTIVE: The present study was to characterize relationships among sexual functioning, schizophrenia symptoms and quality of life measures. In addition, sexual functioning was compared among patients treated with different antipsychotic agents. METHODS: Outpatient subjects were assessed using the Positive and Negative Symptom Scale (PANSS), the Changes in Sexual Functioning Questionnaire (CSFQ) and the Hamilton Rating Scale for Depression (HAMD). Quality of life was assessed using two different instruments: observer-rated Heinrich's Quality of Life Scale (QLS) and self-rated The Behavior and Symptom Identification Scale (BASIS). RESULTS: One hundred twenty-four patients with schizophrenia or schizoaffective disorder were enrolled in the study. Eight-six patients (69%) completed at least part of the CSFQ assessment, which generated at least one valid subscale score. High rates of sexual impairment were found in both male and female patients (65%-94% across different subscales). For males, higher scores on the PANSS-positive subscale were associated with a lower frequency of sexual activity (p=0.04). For females, higher scores on the PANSS-positive subscale and PANSS-general psychopathology subscale were significantly associated with more difficulty in both sexual arousal and orgasm (p's<0.05). For both males and females, there were no significant relationships between any CSFQ subscale measures and the quality of life measures (p's>0.05). No significant differences were found among three antipsychotic treatment groups (clozapine, olanzapine or typical agents) on any CSFQ subscale measures or quality of life measures after controlling for PANSS total scores (p's>0.05). CONCLUSIONS: Effective treatment strategies still need to be developed to address sexual dysfunction and quality of life in patients with schizophrenia.     

The dilemma of insight into illness in schizophrenia: self- and expert-rated insight and quality of life

Introduction A major subgroup of patients with acute schizophrenia lacks awareness of having a mental disorder. The aim of this study was to investigate the association of self- and expert-rated insight into illness with subjective quality of life (QOL). It was hypothesised that patients with greater self- and expert-rated insight into illness report lower QOL compared to patients with poor insight. Method For the present study, patients with schizophrenia or schizoaffective disorders were investigated during in-patient treatment. Insight into illness was measured by the scale to assess unawareness of a mental disorder (SUMD), the insight scale and the PANSS. QOL was assessed with the modular system of quality of life (MSQoL). Results Fifty-nine patients entered the study. Self- and expert-rated illness insight were associated with poor QOL. Patients with good insight into illness reported significantly lower physical health (p < 0.05), vitality (p < 0.01), psychosocial (p < 0.01), affective (p < 0.01) and general QOL (p < 0.001) compared to patients with poor insight. Good insight was significantly associated with other parameters of clinical and social functioning and depressive symptoms. Discussion The results indicate that patients with acute schizophrenia and greater insight realise their restrictions more clearly, which contribute to poor QOL, but were stronger integrated in social networks. The inclusion of modules focussing on QOL related aspects of treatment from the beginning as well as a greater awareness of the physician for these questions and a strengthening of the therapeutic alliance might help improving insight without the risk of deteriorating mood and QOL.     

Socio-demographic and clinical predictors of quality of life in patients with schizophrenia or schizo-affective disorder

This article discusses the relationships between socio-demographic, clinical characteristics and Quality of Life (QOL) of individuals with schizophrenia. The client version of the Canadian version of the Wisconsin Quality of Life Index (CaW-QLI) was used with a population of 182 individuals with either schizophrenia or schizo-affective disorder. Multivariate analyses of variance with Tukey post hoc tests were used to assess differences between groups defined according to socio-demographic and clinical characteristics on all sub-scale scores in addition to the global score on the CaW-QLI. Relationships between socio-demographic characteristics and QOL were found for gender, age, education, employment status and living arrangement. Differences in QOL were found between groups with different clinical characteristics, such as diagnosis, hospitalization during the last 12 months and age at first hospitalization. Using socio-demographic and clinical variables in addition to psychosocial variables appears to be promising for understanding QOL in psychotic patients. Methodological considerations for future research are discussed.     

Sexuality and quality of life of patients with schizophrenia

Patients with schizophrenia continue to have sexual lives despite the nature of their illness. Sexuality, sexual relationships and sexual functioning are all important quality-of-life issues for these patients. Clinicians should be aware of this and not be hesitant to inquire as to the patient's experience and functioning in these areas. The importance of the patient's sexual life should be reflected in our quality of life questionnaires, and be incorporated as part of psychiatric rehabilitation programs through formal sex education.

Suicide attempt and suicidal ideation and their associations with demographic and clinical correlates and quality of life in Chinese schizophrenia patients

Objectives

This study aimed to examine the prevalence and correlates of lifetime suicide attempts and current suicidal ideation in community-dwelling schizophrenia patients in China.

Method

A sample of 540 schizophrenia patients was randomly selected in Beijing, China. All subjects were interviewed using standardized assessment instruments and their basic socio-demographic and clinical data including history of suicide attempts were collected.

Results

The prevalence of lifetime suicide attempts and the point prevalence of suicidal ideation were 12.0 %, and 21.1 %, respectively. In multiple logistic regression analyses, the presence of lifetime suicide attempt was independently associated with rural residence, having major medical conditions and better social functioning, while higher likelihood of current suicidal ideation was associated with past suicide attempt, the severity of overall psychopathology and depressive symptoms and lower psychological quality of life (QOL).

Conclusion

Among Chinese outpatients with schizophrenia, increased current symptoms and poorer QOL were correlated with current suicidal ideation, while demographic factors and indicators of greater social support were mostly correlated with lifetime suicide attempts. This study may help to identify important subgroups of patients with schizophrenia at particularly high risk of suicidal behavior.     

Association between quality of life and self‐stigma,insight, and adverse effects of medication in patients with depressive disorders

Background: The aims of this study were to examine whether different domains of quality of life (QOL) are differently affected by depressive disorders by comparing QOL of subjects with and without depressive disorders, and to examine the association of QOL with self‐stigma, insight and adverse effects of medication among subjects with depressive disorders. Method: The QOL on the four domains of the WHOQOL‐BREF Taiwan version were compared between the 229 subjects with depressive disorders and 106 control subjects. Among the depressive subjects, the association between the four QOL domains and subjects' self‐stigma, insight, and adverse effects of medication were examined using multiple regression analyses by controlling for the influence of depression, socio‐demographic and clinical characteristics and family function. Results: Depressive subjects had poorer QOL on the physical, psychological and social relationship domains than the non‐depressive control group. The depressive subjects who had more severe self‐stigma had poorer QOL on all four domains. The depressive subjects who perceived more severe adverse effects from medication had poorer QOL on the physical, psychological and environmental domains. However, insight was not associated with any domain of QOL in patients with depressive disorders. Conclusions: The results of this study demonstrate that different domains of QOL are differently affected by depressive disorders, and that clinicians must consider the negative influences of self‐stigma and adverse effects from medication on QOL of subjects with depressive disorders.

Demographic, clinical, and neurocognitive predictors of quality of life in schizophrenia patients receiving conventional neuroleptics

We sought to evaluate demographic, clinical, and neurocognitive predictors of self-rated life quality and hospitalization in schizophrenia patients without the potentially cognition-enhancing influence of newer generation neuroleptic medication. A sample of 55 atypical neuroleptic-naive schizophrenia patients was assessed at index and 3 years later. Index neurocognitive measures included general intellectual ability (IQ), executive ability (Wisconsin Card Sorting Test [WCST]), verbal memory (California Verbal Learning Test [CVLT]), and manual dexterity (Purdue Pegboard). These measures, along with demographic (age, sex, education) and clinical (symptoms, prior hospitalizations) variables, were entered into regression equations to predict life quality (Sickness Impact Profile [SIP]) at follow-up, as well as rehospitalization during the 3-year period. Stability data were also analyzed. Demographic and cognitive data predicted subjective quality of life, but not rehospitalization. Changes in memory over time rather than performance levels related to life quality at follow-up. Rehospitalization was related only to demographic data and previous hospital admissions. The findings support the predictive value of selected aspects of neurocognition in relation to a subjective outcome domain in schizophrenia.     

Association of symptom severity,insight and increased pharmacologic side effects in acutely hospitalized patients with schizophrenia

Background

Many studies have shown that more severe symptoms and poorer insight are associated with poor treatment compliance in schizophrenia while severe symptoms may result in higher medication dosages. Since pharmacologic side effects may accompany greater medication compliance and higher medication dosage, the relationship between symptoms, insight and side effects deserves study.

Methods

In this study, 174 inpatients diagnosed with schizophrenia were assessed during the week before hospital discharge from a large psychiatric hospital in Guangzhou, China. Symptoms were measured by the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). Insight was assessed by the Insight and Treatment Attitudes Questionnaire (ITAQ). Pharmacologic side effects were assessed by the Treatment Emergent Symptoms Scale (TESS). Bivariate and multivariate regression models were used to examine the relationship of symptoms, insight and the interaction between the two, to the severity of side effects.

Results

As expected, the PANSS total score was significantly associated with poorer ITAQ scores and with more severe side effects, and on multivariate analysis both higher PANSS and lower ITAQ scores were associated with more severe side effects. Stepwise multiple linear regression analysis showed that the model with the PANSS total score alone explained 3.4% of the variance in side-effect scores, while adding the ITAQ increased the explained variance to 11.8%. Analysis of the interaction of symptoms and insight showed that patients with both more severe symptoms and high insight had the most severe side effects (B = .006, p = .008, R² = 15.4%).

Conclusion

More severe symptoms and greater insight among schizophrenic inpatients were both significantly if modestly associated with more severe pharmacologic side effects, the former presumably because of the need for higher doses of medication and the latter because of greater medication compliance. In addition, patients with both more severe symptoms and greater insight were even more prone to pharmacologic side effects than others presumably reflecting higher doses and higher compliance. Clinicians treating highly symptomatic but insightful patients, i.e. those most likely to need and to adhere to prescribed medications, may need to be especially vigilant about side effects.     

Socio-demographic and clinical correlates of lifetime suicide attempts and their impact on quality of life in Chinese schizophrenia patients

This study determines the socio-demographic and clinical correlates of suicide attempts in Chinese schizophrenia outpatients and their impact on patients' quality of life (QOL). Two hundred and fifty-five clinically stable schizophrenia outpatients were randomly selected in Hong Kong (HK) and their counterparts matched according to sex, age, age at onset and length of illness were recruited in Beijing (BJ). All subjects at both sites were interviewed by the same investigator using standardized assessment instruments. Basic socio-demographic and clinical data and history of suicide attempts were collected. The lifetime prevalence of suicide attempts was 26.7% in the whole sample and 20% and 33.6% in the HK and BJ samples, respectively. Patients with a history of suicide attempts were less likely to receive depot antipsychotic (AP) medication, more likely to receive clozapine, benzodiazepines (BZD) and higher doses of APs; were younger at onset, had more hospitalizations; had more severe positive, depressive, anxiety and extrapyramidal (EPS) symptoms; were poorer QOL in the physical, psychological, social and environmental domains; and were more likely to be BJ residents. In multiple logistic regression analysis, early age at onset, poor physical QOL, use of clozapine and BZDs, and study site (HK vs BJ) were significant contributors to lifetime suicide attempts. Significant difference was found between matched samples in HK and BJ with respect to suicide attempts. HK is a cosmopolitan city with a Western social structure and mental health system, whereas in BJ more traditional Chinese cultural values predominate, with a mental health policy radically different from that of HK. These differences suggest that socio-cultural factors play a significant role in determining suicide attempts in schizophrenia.
