Religion involvement and quality of life in patients with schizophrenia in Latin America

Health-related quality of life and associated factors among patients with schizophrenia at comprehensive specialised hospitals in the Northwest Ethiopia: a multicentre cross-sectional study

OBJECTIVES

The aim of this study was to assess the health-related quality of life (HRQoL) and associated factors among patients with schizophrenia at comprehensive specialised hospitals in Northwest Ethiopia.

DESIGN AND SETTING

A cross-sectional study was conducted among 422 patients with schizophrenia who were followed at comprehensive specialised hospitals in Northwest Ethiopia from 1 June to 30 August 2022.

PARTICIPANTS

All adult patients with schizophrenia who had regular follow-up in the outpatient departments of the selected hospitals were study participants.

MAIN OUTCOME MEASURES

The main outcome of this study was HRQoL which was measured using the WHO Quality of Life Scale-Bref Version. Data entry and analysis were done using Epi-data version 4.6.1 and SPSS version 24, respectively. Linear regression was used to assess the association between quality of life and independent variables. Variables with a p value <0.05 at a 95% CI were considered statistically significant.

RESULTS

The mean score of the overall Quality of Life Scale-Brief Version was 22.42±3.60. No formal education (ß=-1.53; 95% CI: -2.80 to -0.27), duration of treatment (ß = -3.08; 95% CI: -4.71 to -1.45), comorbidity (ß=-1.14; 95% CI: -1.99 to -0.29), substance use (ß=-0.89; 95% CI: -1.56 to -0.23), extrapyramidal side effects (ß=-2.02; 95% CI: -2.90 to -1.14), non-adherence (ß=-0.83; 95% CI: -1.44 to -0.23), and antipsychotic polypharmacy (ß=-1.77; CI: -2.57 to -0.96) were negatively associated with quality of life.

CONCLUSION AND RECOMMENDATION

In this study, the social domain was recorded as having the lowest mean score, which may indicate that patients with schizophrenia could need better psychosocial support. Patients with a longer duration of treatment, who had comorbid illnesses, were substance users, developed EPS, were non-adherent to medications and were on antipsychotic polypharmacy, needs critical follow-up to improve HRQoL.

Religiosity and prevalence of suicide, psychiatric disorders and psychotic symptoms in the French general population

We aimed to examine the association between religious beliefs and observance and the prevalence of psychiatric disorders, psychotic symptoms and history of suicide attempts in the French general population. The cross-sectional survey interviewed 38,694 subjects between 1999 and 2003, using the MINI. Current religious beliefs and observance were identified by means of two questions: "are you a believer?" and "are you religiously observant?". We studied the association between religiosity and psychiatric outcomes using a multivariable logistic regression model adjusted for sociodemographic characteristics, including migrant status. Religious beliefs were positively associated with psychotic symptoms and disorders [OR = 1.37, 95% CI (1.30-1.45) and OR = 1.38, 95% CI (1.20-1.58)], unipolar depressive disorder [OR = 1.15, 95% CI (1.06-1.23)] and generalized anxiety disorder [OR = 1.13, 95% CI (1.06-1.21)], but negatively associated with bipolar disorder [OR = 0.83, 95% CI (0.69-0.98)], alcohol use disorders [OR = 0.69, 95% CI (0.62-0.77)], substance use disorders [OR = 0.60, 95% CI (0.52-0.69)] and suicide attempts [OR = 0.90, 95% CI (0.82-0.99)]. Religious observance was positively associated with psychotic symptoms and disorders [OR = 1.38, 95% CI (1.20-1.58) and OR = 1.25, 95% CI (1.07-1.45)], but negatively associated with social anxiety disorder [OR = 0.87, 95% CI (0.76-0.99)], alcohol use disorders [OR = 0.60, 95% CI (0.51-0.70)], substance use disorders [OR = 0.48, 95% CI (0.38-0.60)] and suicide attempts [OR = 0.80, 95% CI (0.70-0.90)]. Among believers, religious observance was not associated with psychotic outcomes. Religiosity appears to be a complex and bidirectional determinant of psychiatric symptoms and disorders. In this respect, religiosity should be more thoroughly assessed in epidemiological psychiatric studies, as well as in clinical practice.

Associations between perceived environmental pollution and health-related quality of life in a Chinese adult population

BACKGROUND

Health-related quality of life (HRQoL) measures are being used in increasingly diverse populations. However, there have no known studies to date to examine the associations between perceived environmental pollution and HRQoL in a Chinese population. This study aimed to report the associations between air, water, noise pollution and HRQoL among Chinese adult population.

METHODS

A cross-sectional survey data was used from East Asian Social Survey 2010 with a sample of 3866 Chinese populations regarding environmental pollution. HRQoL was computed by SF-12 and reflected by physical and mental component summary score (PCS & MCS). Ordinary least regression analyses were used to examine associations between perceived environmental pollution and PCS and MCS scores. Models in SPSS PROCESS were selected to demonstrate the moderating and mediating effects.

RESULTS

Only considering one pollutant, perceived air pollution and perceived water pollution had significant associations with PCS and MCS scores. Perceived noise pollution had significant associations with PCS scores. Perceived air×noise, air×water, noise×water, and air×noise×water pollution had significant associations with PCS and MCS scores. Conditional (moderated) mediation showed that there were no moderating effects and mediating effects of perceived one pollutant on another pollutant.

CONCLUSIONS

Co-occurring perceived environmental pollution were mainly associated with progressive increase in PCS and MCS scores among the Chinese adult population. These results suggested that some effective policies should be carried out to improve environmental quality in Chinese adult population.

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.

The Relationship Between Religious Beliefs and Quality of Life Among Patients With Multiple Sclerosis

Patients with chronic diseases, such as multiple sclerosis (MS), are prone to emotional distresses and reduction in life quality more than others. This study aimed to assess the relationship between religious beliefs and quality of life among patients with MS. In this study, 145 MS patients completed 36-Item Short-Form Health Survey (SF-36) and the Duke University Religion Index (DUREL) questionnaires. The results indicated that unorganized religious activities were significantly associated with marital status and education level. Besides, internal religion was positively correlated to mental health. However, religious variables were not effective prognostic factors in physical and mental quality of life. Overall, further studies have to be conducted to determine the role of religion in quality of life of MS patients with different religious backgrounds.

Domains of quality of life freely expressed by cancer patients and their caregivers: contribution of the SEIQoL

Background

The purposes of this study, performed on a large sample of cancer patient-caregiver dyads, were: i) to simultaneously investigate, using an individualized quality of life (QoL) measure (Schedule for the Evaluation of Individual QoL, SEIQoL), the QoL domains freely expressed by cancer patients and their caregivers, and ii) to explore overlapping between the SEIQoL assessment and QoL assessment using traditional instruments.

Methods

The study employed a cross-sectional design including cancer patients who were going to receive chemotherapy treatment and their caregivers. Quality of life was assessed using condition-specific questionnaires (EORTC QLQ-C30 and CarGOQoL), generic health-related questionnaire (SF-36), and open individualized measure (SEIQoL).

Results

The final sample included 205 patient-caregiver dyads. From the SEIQoL, Family, Health, and Leisures were the most freely expressed QoL domains by patients and caregivers, but reported with different weights. Love life and financial issues were less spontaneously mentioned. The SEIQoL index was moderately correlated to the condition-specific QoL questionnaires (R lower than |0.40|) and to SF-36 (correlation coefficients: R ranging from 0.17 to 0.31).

Conclusion

Individualized QoL measures allow individuals to spontaneously express important, non-predefined domains. This study highlights the need to explore QoL using a combination of individualized questionnaires and standardized questionnaires, capturing complementary facets that patients consider important in their life.

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.

Religion involvement and quality of life in caregivers of patients with schizophrenia in Latin-America

The aim of the study was to explore the relationship between religious involvement (RI) and quality of life (QoL) in caregivers of patients with schizophrenia, while adjusting for key confounding factors such as socio-demographic and clinical characteristics. This study was conducted in the public mental health services in Bolivia, Peru and Chile. The data collected included RI, socio-demographic information, clinical characteristic of the patients and caregiver's QoL using the S-CGQoL questionnaire. A multivariate analysis using multiple linear regressions was performed to determine variables potentially associated with QoL levels. Two hundred and fifty-three patients with their caregivers participated in the study. Caregivers' RI was not significantly associated with overall QoL nor its individual components. The only exception was an unexpected modest inverse association between RI and one QoL dimension (psychological and physical well-being). In contrast, the following caregivers' socio-cultural and economic factors were significantly associated with low QoL level of caregivers: being a mother, identifying with Aymara ethnicity and having lower family income. Among patients, the clinical characteristics of being woman, younger, and having lower age of onset and more severe symptoms was associated with lower QoL. Our study found that socio-cultural, economic and clinical factors were associated with caregivers' QoL.
