Loneliness and related factors among people with schizophrenia in Japan: a cross-sectional study

Determinants and outcomes of health-promoting lifestyle among people with schizophrenia

BACKGROUND

Healthy lifestyle is an important protective factor of developing cardiovascular disease in people with schizophrenia. However, little is known about the determinants of lifestyle and its contribution to metabolic syndrome. This study aimed to explore the influencing factors of health-promoting lifestyle (HPL) and its association with metabolic syndrome among people with schizophrenia.

METHODS

A cross-sectional study was conducted in twenty-two primary health centers of Guangzhou, China between December 2022 and April 2023. A total of 538 patients with schizophrenia were recruited through convenience sampling. Self-administered scales, questionnaires, and clinical data were collected. Scales and questionnaires included social-demographic information, Health-Promoting Lifestyles Profile (HPLP-C), UCLA Loneliness Scale (ULS), and International Physical Activity Questionnaire-Short Form (IPAQ-SF). Cluster analyses were used to divide participants into two groups based on the distribution characteristics of HPLP-C scores. Logistic regression models were used to identify factors associated with HPL and the association between HPL and metabolic syndrome.

RESULTS

There were 271 participants in the high HPL group and 267 participants in the low HPL group. Logistic regression analysis revealed that loneliness posed a risk factor for high HPL, while high education and moderate-vigorous physical activity served as protective factors for high HPL. Low HPL was a risk factor for the prevalence of metabolic syndrome.

CONCLUSIONS

Promotion of high education literacy and a physically active lifestyle should be priority targets in the health management of schizophrenia. Primary healthcare providers can play a pivotal role in assisting patients to mitigate metabolic syndrome by reinforcing healthy lifestyle strategies.

An exploration of loneliness experienced by people living with mental illness and the impact on their recovery journey: An integrative review

WHAT IS KNOWN ON THE SUBJECT?: There is evidence that social isolation and loneliness is more prevalent in people living with mental illness than in the general population. People living with mental illness frequently experience stigma, discrimination, rejection, repeated psychiatric admissions, low self-esteem, low self-efficacy, and increased symptoms of paranoia, depression, and anxiety. There is evidence of common interventions that can be used to improve loneliness and social isolation such as psychosocial skills training and cognitive group therapy. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This paper offers a comprehensive assessment of the evidence between mental illness, loneliness, and recovery. The results suggest that people living with mental illness experience elevated levels of social isolation and loneliness leading to poor recovery and quality of life. Social deprivation, social integration and romantic loneliness are related to loneliness, poor recovery, and reduced quality of life. A sense of belonging, ability to trust and hope are important aspects of improved loneliness, quality of life and recovery. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The existing culture in mental health nursing practice needs to be examined to address loneliness in people living with mental illness and its impact on recovery. Existing tools to research loneliness do not consider dimensions in loneliness experience as reflected in the literature. Practice needs to demonstrate an integrated approach to recovery, optimal service delivery and augmentation of evidence-based clinical practice to improve individual's loneliness, social circumstances, and relationships. Practice needs to demonstrate nursing knowledge in caring for people living with mental illness experiencing loneliness. Further longitudinal research is required to clearly understand the relationship between loneliness, mental illness, and recovery.

ABSTRACT

INTRODUCTION: To our knowledge, there are no previous reviews on the impact of loneliness experienced by people aged 18-65, who are living with mental illness and their recovery experience.

AIM/QUESTION

To explore the experience and impact of loneliness in people living with mental illness during recovery.

METHOD

An integrative review.

RESULTS

A total of 17 papers met the inclusion criteria. The search was conducted using four electronic databases: MEDLINE, CINAHL, Scopus and PsycINFO. Across these 17 papers, participants were most commonly, diagnosed with schizophrenia or psychotic disorders and recruited from community mental health services.

DISCUSSION

The review revealed loneliness to be substantial in people living with mental illness and that loneliness affected their recovery, and their quality of life. The review identified many factors that contribute to loneliness including unemployment, financial strain, social deprivation, group housing, internalized stigma and mental illness symptoms. Individual factors such as social/community integration and social network size as well as an inability to trust, a sense of not belonging, hopelessness and lack of romance were also evident. Interventions targeting social functioning skills and social connectedness were found to improve social isolation and loneliness.

IMPLICATIONS FOR PRACTICE

It is vital for mental health nursing practice to employ an approach integrating physical health as well as social recovery needs, optimal service delivery and augmentation of evidence-based clinical practice to improve loneliness, recovery, and quality of life.

Association of loneliness with suicide risk and depression in individuals with schizophrenia: moderating effects of self-esteem and perceived support from families and friends

Loneliness is prevalent among individuals with mental illnesses. This cross-sectional survey study examined the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression in individuals with schizophrenia. In total, 300 participants (267 with schizophrenia and 33 with schizoaffective disorder) completed the University of California, Los Angeles, Loneliness Scale (Version 3); suicide module of the Mini International Neuropsychiatric Interview; Center for Epidemiologic Studies Depression Scale; Family and Friend Adaptability, Partnership, Growth, Affection, and Resolve Index; and Rosenberg Self-Esteem Scale. Moderation analysis was performed to examine the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression. The results found that self-esteem was significantly associated with a reduced magnitude of depression in participants with loneliness. In addition, perceived support from friends was significantly associated with a reduced magnitude of suicide risk in participants with loneliness. Our findings indicate the importance of intervention programs that strengthen support from friends and self-esteem in reducing suicide risk and depression among lonely individuals with schizophrenia.

Prevalence of loneliness and its correlates among patients with schizophrenia

BACKGROUND

There are limited data on loneliness and its correlates in patients with schizophrenia.

OBJECTIVE

To evaluate prevalence and correlates of loneliness in patients with schizophrenia, currently in clinical remission.

METHODOLOGY

A total of 160 patients of schizophrenia in clinical remission were assessed on UCLA Loneliness Scale, Positive and Negative syndrome scale, Calgary Depression Scale for Schizophrenia (CDSS), Internalized Stigma of Mental Illness Scale, Rosenberg Self-esteem Scale, Brief COPE, Beck's Hopelessness Scale, Brief Dyadic Scale of Expressed Emotions, and Self-report Quality of Life Measure.

RESULTS

The mean age of the study sample was 34.99 (SD = 9.13) years. The prevalence of loneliness in the study sample was 80%, with mean total UCLA-loneliness scale score of 30.04 (16.9).Compared to participants without loneliness, those with loneliness had had higher CDSS score, had poor quality of life, lower self-esteem, experienced higher level of stigma, more often used maladaptive coping strategies such as self-blaming and reported a higher level of hopelessness. In the correlation analysis, higher level of loneliness was associated higher severity of depression, higher level of stigma (except for stigma resistance) and discrimination, poorer quality of life, lower self-esteem, perception of a higher level of expressed emotions, higher use of maladaptive coping in the domains of behavioral disengagement, and self-blaming, and a higher level of hopelessness. In regression analysis, the maximum variance of loneliness was explained by quality of life score (29%), followed by hopelessness score (8.8%) and discrimination score (2%).

CONCLUSION

There is a high prevalence of loneliness in patients with schizophrenia, and there is a need to routinely evaluate the patients of schizophrenia for loneliness and address the same.

Health-related quality of life in people with psychotic disorders: The role of loneliness and its contributors

BACKGROUND

Perception of loneliness has been identified as the strongest predictor of health-related quality of life assessed with the Assessment of Quality of Life-4D in people with psychotic disorders. We aimed to establish contributors to perceived loneliness, and ascertain the mediating role of loneliness in the relationship between identified contributors to loneliness and other known predictors of health-related quality of life with health-related quality of life.

METHODS

Data for 1642 people collected as part of the 2010 Australian National Survey of Psychosis were analysed. Health-related quality of life was assessed using the Assessment of Quality of Life-4D, and loneliness through a single-item five-level categorical variable. To identify independent contributors to loneliness, a statistical model was constructed with reference to a theoretical model comprising 23 variables. A predictive model with health-related quality of life as the dependent variable was then developed and tested to assess the mediating role of loneliness.

RESULTS

Nine contributors to loneliness were found (social dysfunction, experienced stigma, contact with friends, diagnosis, depressive symptoms, anxiety, mental health service utilisation, arthritis and traumatic events in childhood), with social dysfunction the strongest. In the prediction of health-related quality of life, all contributors to loneliness were partially mediated through loneliness (except service utilisation) as were negative symptoms and use of psychotropic/anticholinergic medications.

CONCLUSION

Assuming a plausible causal model of mediation, loneliness was found to have direct and indirect effects on health-related quality of life in people with psychotic disorders. Findings add impetus to efforts to develop and trial strategies aimed at reducing loneliness in this population, and, in turn, improving their health-related quality of life.

The effect of insight, loneliness, and hope levels on medication adherence in patients with schizophrenia

PURPOSE

It is important to investigate the negative factors affecting medication compliance to continue the treatment of schizophrenia.

DESIGN AND METHODS

In this descriptive and analytical study, the effects of insight, loneliness, and hope levels on medication adherence in 202 patients with schizophrenia were studied.

FINDINGS

The correlation was positive between medication adherence and insight, negative between medication adherence and loneliness, and no correlation between medication adherence and hope. A 1-point increase in insight scores increased medication adherence 1.226 times and a 1-point increase in loneliness scores decreased medication adherence 0.946 times. Medication adherence was 0.499 times lower in nonsmokers compared to smokers.

PRACTICE IMPLICATIONS

Further studies on patients with schizophrenia should be conducted to evaluate factors affecting medication adherence and preventing smoking in schizophrenia.

Has Smartphone Use Influenced Loneliness during the COVID-19 Pandemic in Japan?

The influence of smartphone use on increased risk of feeling lonely has been recognized as a global public health concern. However, it is unclear whether this influence has changed during the ongoing COVID-19 pandemic, during which smartphones have become a particularly important means of communication due to health safety measures restricting personal interactions. We used Hiroshima University's online survey data collected from 18-28 February 2022, to assess the impact of smartphone use on loneliness in Japan. The final sample included 2630 participants aged over 20 years, with loneliness measured using the UCLA scale and smartphone use calculated as the duration of usage in minutes/day. Weighted logit regression analysis was used to examine the association between smartphone use and loneliness, with other demographic, socioeconomic, and psychological characteristics as explanatory variables. Contrary to conventional evidence, our findings show that smartphone use mitigated the risk of loneliness during the pandemic. This was especially true among females under 65 years old. We found that age, subjective health status, future anxiety, and depression impacted this relationship. The findings of this study can help guide policymaking by showing the importance of providing adequate digital platforms to manage loneliness and mental health during times of isolation.

Comparing the Psychometric Properties among Three Versions of the UCLA Loneliness Scale in Individuals with Schizophrenia or Schizoaffective Disorder

The UCLA Loneliness Scale (Version 3; UCLA-LSV3) is widely used for assessing loneliness. Nevertheless, the validity of this scale for assessing loneliness in individuals with schizophrenia or schizoaffective disorder has not been determined. Additionally, studies validating the eight-item and three-item versions of UCLA-LSV3 have not included individuals with severe mental illness; therefore, whether the short versions are comparable to the full 20-item version of UCLA-LSV3 for this population is unclear. The present study examined the unidimensional structure, internal consistency, concurrent validity, and test–retest reliability of the Chinese versions of UCLA-LSV3 (i.e., 20-item, 8-item, and 3-item versions) to determine which version is most appropriate for assessing loneliness in individuals with schizophrenia or schizoaffective disorder in Taiwan. A total of 300 participants (267 with schizophrenia and 33 with schizoaffective disorder) completed the scales, comprising UCLA-LSV3, the Center for Epidemiological Studies Depression Scale (CES-D), the suicidality module of the Kiddie Schedule for Affective Disorders and Schizophrenia–Epidemiological Version (K-SADS-E), and the family and peer Adaptation, Partnership, Growth, Affection, and Resolve (APGAR) index. Construct validity was evaluated through confirmatory factor analysis. The three versions of UCLA-LSV3 were compared with the CES-D, the suicidality module of the K-SADS-E, and the family and peer APGAR index to establish concurrent validity. The results indicated that all three versions of UCLA-LSV3 exhibited acceptable to satisfactory psychometric properties in terms of unidimensional constructs, concurrent validity, and test–retest reliability. The full version of UCLA-LSV3 had the best performance, followed by the eight-item version and the three-item version. Moreover, the three versions had relatively strong associations with each other. Therefore, when deliberating which version of UCLA-LSV3 is the best choice for assessing loneliness in individuals with schizophrenia or schizoaffective disorder, healthcare providers and therapists should consider time availability and practicality.

Loneliness among people with severe mental illness during the COVID-19 pandemic: Results from a linked UK population cohort study

AIM/GOAL/PURPOSE

Population surveys underrepresent people with severe mental ill health. This paper aims to use multiple regression analyses to explore perceived social support, loneliness and factor associations from self-report survey data collected during the Covid-19 pandemic in a sample of individuals with severe mental ill health.

DESIGN/METHODOLOGY/APPROACH

We sampled an already existing cohort of people with severe mental ill health. Researchers contacted participants by phone or by post to invite them to take part in a survey about how the pandemic restrictions had impacted health, Covid-19 experiences, perceived social support, employment and loneliness. Loneliness was measured by the three item UCLA loneliness scale.

FINDINGS

In the pandemic sub-cohort, 367 adults with a severe mental ill health diagnosis completed a remote survey. 29-34% of participants reported being lonely. Loneliness was associated with being younger in age (adjusted OR = -.98, p = .02), living alone (adjusted OR = 2.04, p = .01), high levels of social and economic deprivation (adjusted OR = 2.49, p = .04), and lower perceived social support (B = -5.86, p < .001). Living alone was associated with lower perceived social support. Being lonely was associated with a self-reported deterioration in mental health during the pandemic (adjusted OR = 3.46, 95%CI 2.03-5.91).

PRACTICAL IMPLICATIONS

Intervention strategies to tackle loneliness in the severe mental ill health population are needed. Further research is needed to follow-up the severe mental ill health population after pandemic restrictions are lifted to understand perceived social support and loneliness trends.

ORIGINALITY

Loneliness was a substantial problem for the severe mental ill health population before the Covid-19 pandemic but there is limited evidence to understand perceived social support and loneliness trends during the pandemic.

Socioemotional mechanisms of loneliness in subclinical psychosis

Loneliness is an important predictor of physical and mental health in the general population and in individuals across the psychosis spectrum, including those experiencing subclinical psychotic-like experiences (PLEs). However, the mechanisms underlying loneliness in the psychosis spectrum are not well understood. Emotion processing deficits are well described across the psychosis spectrum, and socioemotional processing biases are critical for the development and maintenance of loneliness through altered social appraisal, including judgements of rejection. Therefore, we propose that PLEs are associated with increased loneliness, and the relationship is mediated by alterations in socioemotional processing. We also explored how this pathway may be affected by mood and anxiety symptoms, which have been associated with loneliness across the psychosis spectrum. As part of the Human Connectome Project, generally healthy adults (n = 1180) reported symptomatology and social functioning and completed the Penn Emotion Recognition Task to assess efficiency in identifying emotions. We found that higher reported PLEs were associated with elevated levels of loneliness and perceived rejection and that these factors were linked by multiple independent pathways. First, anxiety/depression and emotion processing efficiency independently mediated the PLE-loneliness relationship. Second, we found that the association between PLEs and loneliness was serially mediated through inefficient emotion recognition then higher levels of perceived rejection. These separable mechanisms of increased loneliness in subclinical psychosis have implications for treatment and continued study of social functioning in the psychosis spectrum.

Experiences and perceptions of people living with schizophrenia in Japan: A qualitative study

This descriptive study used a qualitative inductive approach to investigate the subjective experiences and perceptions of people with schizophrenia living in the community during times of difficulty and how they coped. We conducted semi-structured interviews with nine community-dwelling people with schizophrenia and used the KJ method developed by Kawakita Jiro to structure the data obtained. We identified 10 symbols with his method: bewilderment at the onset; helplessness and longing for death; solitude linked to death; precarious daily life; relationships at risk; fear of being stigmatized; pillars of emotional support; will to overcome; hope to never give up; and living with the illness. The results suggest that community mental health nurses should provide support so their patients can continue to have pillars of emotional support and the will to overcome difficulties, as well as continue to use their coping methods, even when experiencing many difficulties. It is important that nurses understand and share in their patients' difficult experiences and hopes when providing support toward their recovery.

Disentangling the relationships between interpersonal competence, social network, social support and the experience of being stigmatized among people with psychotic disorders: A path modeling approach

BACKGROUND

Deficits in social skills are common among people with psychosis and may contribute to the severity of the stigmatization they experience. The aim of the present research was to shed light on the mechanisms through which lack of interpersonal competence may lead to an increased exposure to stigma by investigating the mediating effects of social network and social support.

METHODS

A sample of 207 patients diagnosed with psychotic disorders was recruited for the study. The pattern of relationships between interpersonal competence, social network, social support and experienced stigma was analyzed using path modeling.

RESULTS

The level of interpersonal competence was found to be directly negatively related to the intensity of experienced stigma (β = -0.20, SE = 0.08; P < 0.05) and directly positively related to the scope of social network (β = 0.36, SE = 0.08, P < 0.01) and social support (β = 0.36, SE = 0.08, P < 0.01). The analysis of mediation pathways between interpersonal competence and stigma experiences revealed significant indirect effect through social support (β_IND = -0.08, 95% CI: -0.16 to -0.02) and sequential effect through social network and social support (β_IND = -0.03, 95% CI: -0.06 to -0.01). The indirect pathway from interpersonal competence to stigma via social network alone turned out to be non-significant.

CONCLUSIONS

The findings indicate that poor interpersonal competence may increase the extent of the stigma experienced by people with psychotic illness both directly and indirectly, with social support being the key mediator. Since interpersonal competence, social network and social support are potentially modifiable factors, they should be considered as possible targets of anti-stigma interventions.

Factors Associated With Loneliness: An Umbrella Review Of Observational Studies

BACKGROUND

Evidence provides inconsistent findings on risk factors and health outcomes associated with loneliness. The aim of this work was to grade the evidence on risk factors and health outcomes associated with loneliness, using an umbrella review approach.

METHODS

For each meta-analytic association, random-effects summary effect size, 95% confidence intervals (CIs), heterogeneity, evidence for small-study effect, excess significance bias and 95% prediction intervals were calculated, and used to grade significant evidence (p<0.05) from convincing to weak. For narrative systematic reviews, findings were reported descriptively.

RESULTS

From 210 studies initially evaluated, 14 publications were included, reporting on 18 outcomes, 795 studies, and 746,706 participants. Highly suggestive evidence (class II) supported the association between loneliness and incident dementia (relative risk, RR=1.26; 95%CI: 1.14-1.40, I² 23.6%), prevalent paranoia (odds ratio, OR=3.36; 95%CI: 2.51-4.49, I² 92.8%) and prevalent psychotic symptoms (OR=2.33; 95%CI: 1.68-3.22, I² 56.5%). Pooled data supported the longitudinal association between loneliness and suicide attempts and depressive symptoms. In narrative systematic reviews, factors cross-sectionally associated with loneliness were age (in a U-shape way), female sex, quality of social contacts, low competence, socio-economic status and medical chronic conditions.

LIMITATIONS

Low quality of the studies included; mainly cross-sectional evidence.

CONCLUSIONS

This work is the first meta-evidence synthesis showing that highly suggestive and significant evidence supports the association between loneliness and adverse mental and physical health outcomes. More cohort studies are needed to disentangle the direction of the association between risk factors for loneliness and its related health outcomes.

Correlates of loneliness among persons with psychotic disorders

INTRODUCTION

Persons diagnosed with schizophrenia spectrum disorders (SSDs) often experience pervasive feelings of loneliness, which are considered a significant barrier to treatment and recovery.

AIM

As impaired social cognition may contribute to increased loneliness and less skillful social interactions, this study examines the relationships between loneliness and measures of social cognition and functional outcome from the Social Cognition Psychometric Evaluation (SCOPE) study.

METHODS

This study evaluated the relationship between loneliness, social cognitive ability, and social functioning in the context of a large-scale psychometric investigation. We also explored the associations of select demographic characteristics and clinical variables on the endorsement of loneliness in persons diagnosed with a psychotic disorder.

RESULTS

Seventy-four stable outpatients with SSDs and 58 healthy controls completed the UCLA Loneliness Scale in addition to the standard SCOPE battery. Our findings support prior research indicating persons diagnosed with a psychotic disorder experience greater levels of loneliness than normative groups. However, the results also indicate that self-reported loneliness is not associated with social cognitive abilities or functional outcome in psychosis. Regression analyses indicate that roughly half the variance in loneliness endorsed by persons with SSDs is accounted for by clinical variables, with loneliness most strongly associated with guilt and self-esteem.

CONCLUSION

These findings suggest that treatments aiming to reduce perceived social isolation in psychosis should incorporate techniques to bolster selfesteem, reduce guilt, and improve depressive symptoms.

Using World Health Organization Disability Assessment Schedule 2.0 in people with schizophrenia: a 4-year follow-up

Little is known about the changes of people with schizophrenia disability in Taiwan who receive routine treatments under the current mental healthcare system. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) was used to assess and track changes in the degree of disability in people with schizophrenia before and after 4 years of follow-up. Data on 4497 people with schizophrenia were acquired from the Taiwan Data Bank of Persons with Disability. The WHODAS 2.0 was used for disability assessment, and the chi-square test, logistic regression and generalised estimating equations were adopted for statistical analysis. People with schizophrenia exhibited improvement in cognition, mobility and participation among the six domains as well as in the overall score. The degree of disability in all domains remained mild to moderate among people aged 18-64 years; the degree of disability in cognition declined from moderate to severe among patients aged ≥65 years. The degree of disability in all domains remained mild to moderate among people with mild to moderate impairment; among those with severe impairment, the degree of disability in the domains of cognition and life activities declined from moderate to severe and the degree of disability in the domain of mobility declined from mild to moderate. Community-dwelling patients exhibited less degree of disability in all domains than their institutionalised peers. Early detection and treatment and an emphasis on communication and social problem-solving skills in rehabilitation programmes are recommended for people with schizophrenia.

Epidemiology of loneliness in a cohort of UK mental health community crisis service users

PURPOSE

Loneliness is an important issue for mental health service users. However, it has not been a particularly prominent focus of recent mental health research. This paper aimed to explore the severity of loneliness among people leaving mental health community crisis services, and to identify factors associated with loneliness.

METHODS

A total of 399 participants experiencing mental health crises recruited for a research trial from community crisis services were included in this cross-sectional study. They completed the eight-item measure of the University of California at Los Angeles Loneliness Scale and a set of instruments assessing socio-demographic, psychosocial, and psychiatric variables.

RESULTS

Severity of loneliness was high among people leaving community crisis services. Longer years since first contact with mental health services (2-10 years, coefficient = 1.83, 95% CI 0.49-3.16; more than 10 years, coefficient = 1.91, 95% CI 0.46-3.36) and more severe affective symptoms (coefficient = 0.32, 95% CI 0.23-0.40) were associated with greater loneliness, whereas bigger social network size (coefficient = - 0.56, 95% CI - 0.76 to - 0.36) and greater social capital (coefficient = - 0.16, 95% CI - 0.31 to - 0.003) were associated with less severe loneliness.

CONCLUSIONS

This paper supports a view that people experiencing mental health crises often report relatively severe loneliness, and that loneliness tends to become more severe during the course of illness. A greater awareness of loneliness among mental health professionals may be beneficial. Loneliness is a potential focus of the development of interventions to improve the lives and outcomes of people with significant mental health problems.

The relationship between internalized stigma and loneliness in patients with schizophrenia

PURPOSE

The study was conducted for the purpose of determining the relationship between internalized stigma and loneliness in patients with schizophrenia.

DESIGN AND METHODS

The population of this correlational-descriptive study consisted of a total of 200 in patients with schizophrenia. The data were collected using "Form of Descriptive Characteristics", "Internalized Stigma of Mental Illness Inventory (ISMI)", and "UCLA Loneliness Scale".

FINDINGS

It was determined that the loneliness level of the patients who participated in the study was 57.20 ± 10.38 and level of of internalized stigma was 79.65 ± 13.48. There was a statistically positive and strong correlation between loneliness and internalized stigma total mean scores of the patients (P = 0.001, r = 0.854).

PRACTISE IMPLICATIONS

It was found that the schizophrenic patients had high levels of internalized stigma and loneliness.

Comparison of schizophrenia outpatients in residential care facilities with those living with someone: Study of mental and physical health, cognitive functioning, and biomarkers of aging

This paper aims to compare mental and physical health, cognitive functioning, and selected biomarkers of aging reflecting metabolic pathology and inflammation, in outpatients with schizophrenia from two residential settings: residential care facilities (RCFs) and living with someone in a house/apartment. This cross-sectional study examined community-dwelling adults with schizophrenia either in RCFs (N = 100) or in a house/apartment with someone (N = 76), recruited for two NIH-funded studies in San Diego. Assessments included measures of mental/physical health, cognitive function, and metabolic (glycosylated hemoglobin, cholesterol) and inflammatory (C-Reactive Protein, Tumor Necrosis Factor-alpha, Interleukin-6) biomarkers of aging. General logistic models were used to analyze factors associated with residential status. RCF residents had several indicators of worse prognosis (never being married, higher daily antipsychotic dosages, increased comorbidities and higher Framingham risk for coronary heart disease) than individuals living with someone. However, RCF residents had better mental well-being and lower BMI, as well as comparable biomarkers of aging as those living with someone. While the cross-sectional nature of the study does not allow us to infer causality, it is possible that the supportive environment of RCFs may have a positive impact on mental and physical health of persons with schizophrenia. Longitudinal follow-up studies are needed to test this hypothesis.

Motivational and cognitive correlates of community integration in homeless veterans entering a permanent supported housing program

Homelessness is a major public health problem, and serious mental illness (SMI) is highly prevalent in the homeless population. Although supported housing services-which provide permanent housing in the community along with case management-improve housing outcomes, community integration typically remains poor, and little is known about the underlying determinants of poor community integration postresidential placement. The general SMI literature has indicated that motivational and cognitive ability factors are key determinants of successful community integration, which provides a foundation for examining this issue. This study evaluated whether interview- and performance-based assessments of motivation, nonsocial and social-cognitive ability, and psychiatric symptoms were associated with community integration indices in 2 samples of homeless veterans either with (N = 96) or without (N = 80) a psychotic disorder who had recently been admitted to a supported housing program but who had not yet attained housing. Motivation indices, including experiential negative symptoms and defeatist performance attitudes, stood out as the most robust correlates (rs = -.30 to -.69) of community integration across both samples, particularly for social role participation. Demographics, general psychiatric symptoms, and nonsocial cognition showed generally weak relations with community integration, though social cognition showed a few relations. The consistent findings across samples point to the importance of motivational factors for understanding the determinants of poor community integration in this complex population. Further, interventions that target motivational challenges may have widespread usefulness for enhancing community integration outcomes beyond obtaining housing.

Loneliness in schizophrenia: Construct clarification, measurement, and clinical relevance

Loneliness is a highly prevalent experience in schizophrenia. Theoretical models developed in the general population propose that loneliness is tantamount to a feeling of being unsafe, is accompanied by enhanced environmental threat perception, and leads to poor physical, emotional, and cognitive functioning. Previous research has reported that loneliness is associated with poorer physical and emotional health in schizophrenia; however, few studies have directly compared loneliness and its correlates in persons with schizophrenia and non-psychiatric comparison subjects. The purpose of the current study was to evaluate similarities and differences in the construct of loneliness, the equivalency of the measurement of this construct, and similarities and differences in the pattern of external correlates of loneliness between schizophrenia and non-psychiatric comparison groups. The third version of the University of California, Los Angeles Loneliness Scale (UCLA-3) was administered to 116 individuals with schizophrenia or schizoaffective disorder and 106 non-psychiatric comparison subjects. Additional clinical and positive psychological measures were collected, as well as demographic characteristics of the two groups. Multiple groups confirmatory factor analysis revealed that the UCLA-3 was best characterized by a bifactor model in which all items loaded on a general loneliness dimension as well as one of two orthogonal method factors reflecting item wording in both groups. Furthermore, the UCLA-3 exhibited invariant measurement of these latent constructs across groups. Mean levels of loneliness were nearly a standard deviation higher in the schizophrenia group. Nonetheless, the overall pattern and strength of correlates were largely similar across groups, with loneliness being positively associated with depression, anxiety, and perceived stress, and negatively correlated with mental well-being, happiness, and resilience. Subtle differences in correlates of age, optimism, and satisfaction with life were found. Overall, loneliness appears to be distinct from other schizophrenia-related deficits and operates similarly across schizophrenia and NC groups, suggesting that theoretical models of loneliness developed in the general population may generalize to schizophrenia.

Investigating the roles of loneliness and clinician- and self-rated depressive symptoms in predicting the subjective quality of life among people with psychosis

PURPOSE

To examine the roles of loneliness and clinician- and self-rated depressive symptoms as predictors of the subjective quality of life (QoL) in psychosis.

METHODS

This cross-sectional study was conducted on a sample of 207 patients diagnosed with psychotic disorders. They were assessed with self-reported measures of QoL, loneliness and depression and with clinician-rated measures of depression and overall psychopathology. Multiple indicators multiple causes (MIMIC) modeling was used to analyze the data.

RESULTS

Both loneliness and depression turned out to be independent predictors of impaired QoL. However, once loneliness was accounted for, the effect of depression on QoL was markedly reduced and the effect of loneliness proved to be visibly larger. Self-rated depression was found to be more strongly associated with QoL than clinician-rated depression. Each type of depression measure explained a unique amount of variance in QoL. Depression moderated the relationship between loneliness and QoL in such a way that the negative effect of loneliness on QoL weakened with the increasing intensity of depressive symptoms.

CONCLUSIONS

Therapeutic programs aiming to enhance the QoL of people with psychotic disorders should incorporate interventions targeting both loneliness and depression and need to be tailored to the clinical status of patients. The emphasis on alleviating loneliness should be placed first of all in the case of those with low levels of depression, among whom the negative impact of loneliness on QoL is especially strong. Researchers should be aware that the method chosen for assessing depressive symptoms in models predicting QoL in psychosis matters.

Assessment of functioning and disability in patients with schizophrenia using the WHO Disability Assessment Schedule 2.0 in a large-scale database

Schizophrenia is a common mental disorder characterized by deficits in multiple domains of functioning. This study is arguably the first of its kind in Taiwan to examine, in a multifaceted and objective manner, the disability of patients with schizophrenia and the factors affecting it. A cross-sectional design was adopted to gather data from 24,299 patients with schizophrenia who were listed in the Taiwan Databank of Persons with Disabilities. The level of disability in these patients was measured using the World Health Organization Disability Assessment Schedule 2.0. Statistical analyses were conducted through the χ ² statistic and Poisson regression. The highest level of disability was in participation and the lowest was in self-care. An analysis of disability in all six domains of functioning on the basis of sex, age, type of residence, and socioeconomic status (SES) showed significant differences (P < 0.05). Significant factors (P < 0.05) affecting disability in these domains were female gender, age, educational attainment, SES, type of residence, and employment status. The overall degree of disability in schizophrenia patients was moderate. Six domains were measured in this study. The degrees of disability in mobility and self-care were mild while cognition, getting along, life activities, and participation were moderate. Moreover, female gender, an age of 45 or older, low educational attainment, middle to low SES, staying at healthcare institutions, and unemployment were crucial factors affecting disability of the participants. Preventive and rehabilitation programs should be developed to delay disability and functional degeneration in schizophrenic patients with these characteristics.
