Loneliness in psychosis: a systematic review

Purpose

The aim of the review is to understand the relationships between loneliness and related psychological and social factors in individuals with psychosis. Loneliness is poorly understood in people with psychosis. Given the myriad of social challenges facing individuals with psychosis, these findings can inform psychosocial interventions that specifically target loneliness in this vulnerable group.

Methods

We adhered to the PRISMA guidelines and systematically reviewed empirical studies that measured loneliness either as a main outcome or as an associated variable in individuals with psychosis.

Results

A total of ten studies examining loneliness in people diagnosed with a psychotic disorder were examined. Heterogeneity in the assessment of loneliness was found, and there were contradictory findings on the relationship between loneliness and psychotic symptomatology. In individuals with psychosis, loneliness may be influenced by psychological and social factors such as increased depression, psychosis, and anxiety, poor social support, poor quality of life, more severe internalised stigma and perceived discrimination, and low self-esteem.

Conclusions

The relationship between loneliness and psychosis remains poorly understood due to a lack of rigorous studies. Although having strong social relationships is crucial to facilitate recovery from serious mental illness, psychosocial interventions that specifically target loneliness in individuals with psychosis are lacking and sorely needed. Interventions targeting loneliness in those with psychosis will also need to account for additional barriers associated with psychosis (e.g., social skill deficits, impoverished social networks, and negative symptoms).

     

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.

     

A life less lonely: the state of the art in interventions to reduce loneliness in people with mental health problems

Purpose

There is growing evidence of significant harmful effects of loneliness. Relatively little work has focused on how best to reduce loneliness in people with mental health problems. We aim to present an overview of the current state of the art in loneliness interventions in people with mental health problems, identify relevant challenges, and highlight priorities for future research and implementation.

Methods

A scoping review of the published and grey literature was conducted, as well as discussions with relevant experts, to propose a broad classification system for types of interventions targeting loneliness.

Results

We categorised interventions as ‘direct’, targeting loneliness and related concepts in social relationships, and ‘indirect’ broader approaches to well-being that may impact on loneliness. We describe four broad groups of direct interventions: changing cognitions; social skills training and psychoeducation; supported socialisation or having a ‘socially-focused supporter’; and ‘wider community approaches’. The most promising emerging evidence appears to be in ‘changing cognitions’, but, as yet, no approaches have a robust evidence base. Challenges include who is best placed to offer the intervention, how to test such complex interventions, and the stigma surrounding loneliness.

Conclusions

Development of clearly defined loneliness interventions, high-quality trials of effectiveness, and identifying which approaches work best for whom is required. Promising future approaches may include wider community initiatives and social prescribing. It is important to place loneliness and social relationships high on the wider public mental health and research agenda.

     

Relative social standing and suicide ideation among Kenyan males: the interpersonal theory of suicide in context

Purpose

The purpose of this study is to investigate the association between subjective social status and suicide ideation in a sample of young Kenyan men (age 18–34 years). Situating insights from the interpersonal theory of suicide within social determinants of health framework, we consider whether lower subjective social status predicts lower collective self-esteem (CSE), hopelessness, less meaning in life and more loneliness, and whether these characteristics mediate associations between subjective social status and suicide ideation.

Method

A community-based, semi-rural sample (n = 532) of young men, aged 18–34 years, was collected using a standardized questionnaire. The survey questionnaire included the following validated scale items: the short form of the Social and Emotional Loneliness Scale for Adults, CSE, Herth Hope Index, the Meaning in Life Questionnaire, and the Modified Scale for Suicide Ideation. Regression and mediation analyses were used to test hypotheses.

Results

Nearly 12% of respondents reported suicide ideation. Suicide ideation was significantly more common among survey respondents who reported lower subjective social standing. In the first of two mediation models, we found that lower CSE and more loneliness mediate the association between lower subjective social status and suicide ideation. In the second model, we found that respondents with lower CSE and more loneliness expressed lower hope and meaning in life, which also mediated pathways to suicide ideation.

Conclusions

Findings show a novel synthesis of social determinants literature with the interpersonal theory of suicide. Suicide ideation, along with other mental and social outcomes, may figure more prominently than previously appreciated in the benefits of socio-economic equality. Those who do not participate equally in socio-economic development may be at greater risk of engaging in suicide ideation and behaviors. Suicide prevention research and programmatic responses should adopt a health equity perspective to ensure that prevention is targeted where people are more likely to engage in suicide ideation.

     

The role of socio-economic status and neighborhood social capital on loneliness among older adults: evidence from the Sant Boi Aging Study

Purpose

The aim of the present study is to analyze the role of age in the association between socio-economic status (SES) and loneliness as well as the role of neighborhood social capital (NSC) in the association between individual social capital and loneliness.

Methods

Data include a representative population-based sample from Sant Boi de Llobregat (a suburb of Barcelona) of 1124 adults aged 50 and over. Logistic regression models were used to analyze the survey data. Interactions between SES and age, and NSC and individual social capital were explored.

Results

Among the poorest older adults, older individuals showed a lower likelihood of loneliness (OR 0.09, 95% CI 0.02, 0.30, p < 0.05) compared with the youngest cohort after adjusting for covariates, while among the richest individuals there were no significant differences among age cohorts. Individuals living in an area with high NSC and high individual social capital showed a lower likelihood of loneliness (OR 0.36, 95% CI 0.17, 0.73, p < 0.05) compared with those with low individual social capital after adjusting for covariates. The effect of individual social capital was not significant among individuals living in an area with low NSC.

Conclusion

Interventions focusing on low SES middle-aged (50–59 years old) individuals and those aiming to increase NSC could be effective strategies to reduce the prevalence of loneliness in older people.

     

Potentially traumatic events have negative and positive effects on loneliness,depending on PTSD-symptom levels: evidence from a population-based prospective comparative study

Purpose

Examine to what extent adults affected by recent potentially traumatic events (PTE) with different PTSD-symptom levels are more at risk for post-event loneliness than non-affected adults are in the same study period.

Methods

We extracted data from the Dutch longitudinal LISS panel to measure pre-event loneliness (2011) and post-event loneliness (2013 and 2014), pre-event mental health problems (2011), PTE and PTSD symptoms (2012). This panel is based on a traditional random sample drawn from the population register by Statistics Netherlands.

Results

Results of the multinomial logistic regression analyses showed that affected adults with high levels of PTSD symptoms were more at risk for high levels of post-event loneliness than affected adults with very low PTSD-symptom levels and non-affected adults, while controlling for pre-event loneliness, pre-event mental health problems and demographics. However, affected adults with very low levels of PTSD symptoms compared to non-affected adults were less at risk for medium and high levels of post-event loneliness while controlling for the same variables. Yet, pre-event loneliness appeared to be the strongest independent predictor of loneliness at later stages: more than 80% with high pre-event levels had high post-event levels at both follow-ups.

Conclusions

Remarkably, potentially traumatic events have depending on PTSD-symptom levels both negative and positive effects on post-event loneliness in favor of affected adults with very low PTSD symptoms levels. However, post-event levels at later stages are predominantly determined by pre-event loneliness levels.

     

Mindfulness Meditation for Chronic Pain: Systematic Review and Meta-analysis

Background

Chronic pain patients increasingly seek treatment through mindfulness meditation.

Purpose

This study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults.

Method

We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use.

Results

Thirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life.

Conclusions

While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

     

Social identity continuity and mental health among Syrian refugees in Turkey

Purpose

Building upon social psychological work on social identity and mental health, this study among Syrian refugees in Turkey examined the importance of multiple group memberships and identity continuity for mental health and well-being.

Method

A survey study was conducted among the very difficult to reach population of Syrian refugees (N = 361). With path analysis in AMOS the associations were examined between multiple group memberships, social identity continuity and mental health and psychological well-being.

Results

Indicate that belonging to multiple groups before migration was related to a higher likelihood of having preserved group memberships after migration (i.e., sense of social identity continuity), which, in turn, predicted greater life satisfaction and lower levels of depression. Multiple group membership, however, was also directly related to higher depression.

Conclusions

Findings are discussed in relation to the importance of multiple group membership and feelings of identity continuity for refugees.

     

Loss of group memberships predicts depression in postpartum mothers

Purpose

The postpartum period presents the highest risk for women’s mental health throughout the lifespan. We aimed to examine the Social Identity Model of Identity Change in this context. More specifically, we investigated changes in social identity during this life transition and their consequences for women’s postpartum mental health.

Methods

Women who had given birth within the last 12 months (N = 387) reported on measures of depression, social group memberships, and motherhood identification.

Results

Analyses indicated that a decrease in group memberships after having a baby, controlling for group memberships prior to birth, was associated with an increase in depressive symptomology. However, maintaining pre-existing group memberships was predictive of better mental health. New group memberships were not associated with depressive symptomology. Identification as a mother was a strong positive predictor of mental health in the postpartum period.

Conclusions

The social identity model of identity change provides a useful framework for understanding postpartum depression. Interventions to prevent and treat postpartum depression might aim to support women in maintaining important social group networks throughout pregnancy and the postpartum period.

     

Views from an asylum: a retrospective case note analysis of a nineteenth century asylum

Purpose

To investigate whether lifelong admission to psychiatric asylum care was usual practice before community psychiatric care was introduced.

Methods

Historical archives (1838–1938) for 50 patients at the Northampton General Lunatic Asylum in England were studied. Regression analyses were performed to investigate associations between predictor variables (age, gender, marital status, social class) and outcomes (diagnoses, length of stay and admission outcomes).

Results

30 patients (70%) were discharged into the community. 15 (31%) patients were admitted longer than 1 year. Diagnosis of mania was significantly higher in patients who were married. Trend associations were observed for melancholia being diagnosed in higher social class patients and monomania being diagnosed in unmarried patients. No associations were found between predictor variables and length of stay or admission outcomes.

Conclusions

These findings challenge the myth that asylum incarceration was a usual practice before the advent of community care. Most patients were discharged from psychiatric asylum hospital within a year of admission even before the advent of psychotropic medication.

     

Affective Personality Traits in Olfactory Dysfunction: the Role of Dysthymia and Arousal

Introduction

Olfactory dysfunction can have a negative impact on emotional well-being. The aim of the present study was to examine associations between olfactory deficits and two affective personality characteristics (trait anxiety/trait depression).

Methods

A questionnaire study was conducted with a total of 116 participants (33 classified as anosmic, 40 as hyposmic, and 39 as normosmic). All participants gave self-reports on two facets of trait depression (dysthymia, euthymia) and trait anxiety (arousal, worrying). Due to the fact that in all three groups, trait depression and anxiety were substantially correlated, analyses of covariance were conducted.

Results

After controlling for trait depression, anosmic and hyposmic patients showed lower trait arousal compared to normosmic controls (partial η ²?=?.05). After controlling for trait anxiety, patients scored higher on dysthymia (partial η ²?=?.06).

Conclusions

This study underlines the importance of statistically isolating specific associations between each of these affective personality characteristics and olfactory dysfunction.

Implications

The present findings suggest that olfactory dysfunction can have opposite effects on facets of trait depression and trait anxiety.

     

The longitudinal association between external locus of control,social cognition and adolescent psychopathology

Purpose

To investigate the longitudinal associations between social cognitive ability an external locus of control (externality) and adolescent psychopathology.

Methods

7058 participants from a prospective population-based cohort provided data on externality, social communication, and emotion perception between 7 and 16 years and psychotic experiences and depressive symptoms at 12 and 18 years. Bivariate probit modelling was used to investigate associations between these risk factors and psychopathological outcomes.

Results

Externality was associated with psychopathology at 12 (psychotic experiences OR 1.23 95% CI 1.14, 1.33; depression OR 1.12 95% CI 1.02, 1.22) and 18 years (psychotic experiences OR 1.38 95% CI 1.23, 1.55; depression OR 1.40 95% CI 1.28, 1.52). Poor social communication was associated with depression at both ages (12 years OR 1.22 95% CI 1.11, 1.34; 18 years OR 1.21 95% CI 1.10, 1.33) and marginally associated with psychotic experiences. There was marginal evidence of a larger association between externality and psychotic experiences at 12 years (p?=?0.06) and between social communication and depression at 12 years (p?=?0.03).

Conclusions

Externality was more strongly associated with psychotic experiences. At 18 years change in externality, between 8 and 16 years were associated with a larger increase in the risk of depression. Poor social communication was more strongly associated with depression.

     

Girls get by with a little help from their friends: gender differences in protective effects of social support for psychotic phenomena amongst poly-victimised adolescents

Purpose

To investigate whether social support is protective for psychotic experiences similarly among poly-victimised adolescent girls and boys.

Methods

We utilised data from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative sample of 2232 UK-born twins. Participants were privately interviewed at age 18 about victimisation, psychotic experiences, and social support during adolescence.

Results

Perceived social support (overall and from friends) was found to be protective against psychotic experiences amongst poly-victimised adolescent girls, but not boys. Though boys were similarly protected by family support.

Conclusions

Social support-focused interventions targeting psychotic phenomena amongst poly-victimised adolescents may be more effective for girls.

     

Individual- and Area-Level Disparities in Access to the Road Network,Subway System and a Public Bicycle Share Program on the Island of Montreal,Canada

Background

Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health.

Purpose

To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada.

Methods

Examining associations between sociodemographic variables and access to the road network, public transportation system, and a public bicycle share program, 6,495 adult respondents (mean age, 48.7 years; 59.0 % female) nested in 33 areas were included in a multilevel analysis.

Results

Individuals with lower incomes lived significantly closer to public transportation and the bicycle share program. At the area level, the interaction between low-education and low-income neighborhoods showed that these areas were significantly closer to public transportation and the bicycle share program controlling for individual and urbanicity variables.

Conclusions

More deprived areas of the Island of Montreal have better access to transportation infrastructure than less-deprived areas.

     

Daily Interpersonal Experience Partially Explains the Association Between Social Rank and Physical Health

Background

Socioeconomic position is a well-established risk factor for poor physical health.

Purpose

This study examines whether the effects of lower social rank on physical health may be accounted for by differences in daily social experience.

Methods

In a large community sample (N?=?475), we examined whether subjective social rank is associated with self-rated health, in part, through positive and negative perceptions of daily interpersonal interactions, assessed using ecological momentary assessment.

Results

Higher social rank was associated with higher average perceived positivity of social interactions in daily life (e.g., B?=?.18, p?<?.001), but not with perceived negativity of social interactions. Further, the association between social rank and self-rated physical health was partially accounted for by differences in perceived positivity of social interactions. This effect was independent of well-characterized objective markers of SES and personality traits.

Conclusions

Differences in the quality of day-to-day social interactions is a viable pathway linking lower social rank to poorer physical health.

     

Fruits and vegetables intake and its subgroups are related to depression: a cross-sectional study from a developing country

Background

The association of fruits and vegetables (FV) specific subgroups consumption and depression has not been investigated in healthy adult populations. Therefore, the aim of our study was to determine the relationship between intake of FV as well as their subgroups and depression.

Methods

This cross-sectional study was conducted on 400 women attending healthcare centers. The scores of depression, anxiety, and stress were measured using the 21-item depression, anxiety and stress scales questionnaire. The participants’ anthropometric and physical activity data were collected and the 147-item semi-quantitative FFQ was used for estimating the FV intake.

Results

After adjustment for confounding variables, the participants in the lower quartiles of total FV, total vegetables, total fruits, citrus, other fruits and green leafy vegetables intake were more likely to experience depression compared to those in the higher quartiles (p trend?<?0.03).

Conclusion

Our findings suggest that higher intake of total FV and some of its specific subgroups might be associated with depression.

     

Contributions of the Life Course Perspective to Research on Food Decision Making

Background

The life course perspective (LCP) has emerged as a powerful organizing framework for the study of health, illness, and mortality. LCP represents a “whole life” analysis perspective which originated in the field of sociology.

Methods

Its concepts are increasingly applied to understanding the development of chronic disease over long periods of time in the human life span. A missing link, however, in the adaptation of the LCP to health research, is the insight the LCP may offer into understanding the societal, social network, and family contexts that frame stability and change in dietary behavior.

Results

This paper reviews key concepts that comprise the LCP but primarily focuses on applications that have relevance to food decision making in social context. A case study of chronic work–family stress and perceived time scarcity as barriers to dietary improvement is included.

Conclusion

Illustrative findings are presented on dietary behavior in a diverse sample of lower-income working parents. This paper also offers ideas on increasing the contributions of the LCP to nutritional research.

     

Extended family and friendship support and suicidality among African Americans

Purpose

This study examined the relationship between informal social support from extended family and friends and suicidality among African Americans.

Methods

Logistic regression analysis was based on a nationally representative sample of African Americans from the National Survey of American Life (N = 3263). Subjective closeness and frequency of contact with extended family and friends and negative family interaction were examined in relation to lifetime suicide ideation and attempts.

Results

Subjective closeness to family and frequency of contact with friends were negatively associated with suicide ideation and attempts. Subjective closeness to friends and negative family interaction were positively associated with suicide ideation and attempts. Significant interactions between social support and negative interaction showed that social support buffers against the harmful effects of negative interaction on suicidality.

Conclusions

Findings are discussed in relation to the functions of positive and negative social ties in suicidality.

     

Neural correlates of socio-emotional perception in 22q11.2 deletion syndrome

Background

Social impairments are described as a common feature of the 22q11.2 deletion syndrome (22q11DS). However, the neural correlates underlying these impairments are largely unknown in this population. In this study, we investigated neural substrates of socio-emotional perception.

Methods

We used event-related functional magnetic resonance imaging (fMRI) to explore neural activity in individuals with 22q11DS and healthy controls during the visualization of stimuli varying in social (social or non-social) or emotional (positive or negative valence) content.

Results

Neural hyporesponsiveness in regions of the default mode network (inferior parietal lobule, precuneus, posterior and anterior cingulate cortex and frontal regions) in response to social versus non-social images was found in the 22q11DS population compared to controls. A similar pattern of activation for positive and negative emotional processing was observed in the two groups. No correlation between neural activation and social functioning was observed in patients with the 22q11DS. Finally, no social × valence interaction impairment was found in patients.

Conclusions

Our results indicate atypical neural correlates of social perception in 22q11DS that appear to be independent of valence processing. Abnormalities in the social perception network may lead to social impairments observed in 22q11DS individuals.

     

Idiopathisch generalisierte Epilepsien

Background

Although the sociomedical importance of epilepsies has been extensively investigated, data regarding social long-term outcome and quality of life of people with idiopathic generalized epilepsies (IGE) are lacking.

Objectives

Predictors for the psychosocial outcome and the quality of life in patients with IGE are identified and discussed.

Materials and methods

The findings of existing studies on the social outcome in patients with various IGE syndromes are analyzed and discussed.

Results

Patients with absence epilepsy or juvenile myoclonic epilepsy (JME) are reported to have an unfavorable psychosocial outcome. While in JME a lower seizure frequency or remission of the epilepsy correlates with a favorable psychosocial outcome and a higher quality of life, remission of epilepsy is not predictive for a better social outcome among patients with absence epilepsy. Compared to other IGE syndromes, IGE with generalized, tonic–clonic seizures on awakening appears have a more favorable psychosocial outcome.

Conclusion

Several predictors for the psychosocial outcome and the quality of life have been identified and may potentially increase the clinicians’ ability and confidence to recommend different treatment options to patients with IGE.
