Self-disgust as a potential mechanism explaining the association between loneliness and depression

Loneliness trajectories and predictors in Spain: Results from the Spanish longitudinal study on aging and health (Edad con Salud)

BACKGROUND

In recent years, loneliness has been recognized as a public health problem, exacerbated by the COVID-19 pandemic. This study aims to identify groups of people with different trajectories of loneliness, and to explore potential determinants (sociodemographic, social, psychological, and health-related) associated with these trajectories.

METHODS

In this 12-year longitudinal study, we analyzed data on 4537 Spanish adults from a nationwide representative survey. A growth mixture modeling approach was used to identify different loneliness trajectories and logistic regressions to explore the determinants of these trajectories.

RESULTS

Two trajectory classes were identified: low-stable (87.86 %) and high-fluctuating (12.14 %). Marital status, living status, migration, social isolation, depression, suicidal ideation, and cognitive complaints were identified as significant determinants of belonging to the high-fluctuating trajectory. Conversely, social support, social trust, and life satisfaction were protective factors for this trajectory.

CONCLUSION

This study revealed the presence of diverse courses of loneliness (each showing some distinctive characteristics from the other), outlining some relevant implications for the assessment, prevention, and management of loneliness.

Emotion regulation and mental health across cultures: a systematic review and meta-analysis

Emotion regulation (ER) plays a central role in mental health, but the effect differs across cultures. Here, expanding from extant literature's focus on Western-Eastern dichotomy or individualism-collectivism, this meta-analysis synthesized evidence on the associations between the two most-studied ER strategies (cognitive reappraisal and expressive suppression) and two mental health outcomes (psychopathology and positive functioning) and investigated the moderating roles of several cultural dimensions: Hofstede's national cultures dimensions, education, industrialization, richness and democracy (EIRDness), and sample demographics. A comprehensive literature search was conducted using electronic databases (CINAHL, Scopus, Web of Science, PsycINFO and MEDLINE) to identify eligible studies reporting relationships between ER and mental health outcomes (PROSPERO: CRD42021258190, 249 articles, n = 150,474, 861 effect sizes, 37 countries/regions). For Hofstede's national cultures and EIRDness, multimodel inference revealed that greater reappraisal propensity was more adaptive in more short-term-oriented, uncertainty-tolerant and competition-driven cultures, whereas greater suppression propensity was more maladaptive in more indulgent and competition-driven cultures. For demographics, greater reappraisal propensity was more adaptive for samples with more female (B = -0.19, 95% confidence interval (CI) -0.29 to -0.09) and more racial minority participants (B = -0.32, 95% CI -0.51 to -0.13), whereas greater suppression propensity was more maladaptive in younger samples (B = -0.004, 95% CI -0.005 to -0.002). These findings elucidate how cultures are associated with the function of ER and suggests ways in which future studies can integrate cultural characteristics when examining ER and psychological adjustment.

The Relationships Between Loneliness, Emotional Intelligence, and Depression Among Turkish Emerging Adults: A Moderated Moderation Model in the Gender Context

Loneliness is a common public health problem that can influence individuals' depression outcomes. The incidence of loneliness among emerging adults is high. From this perspective, this study would serve two primary aims in Turkish emerging adults. The first was to examine the moderating effect of emotional intelligence on the relationship between loneliness and depression. The second was to test whether gender moderated this moderating effect. The study sample consisted of 456 (213 females and 243 males) university-attending emerging adults, 18-25 years old. Firstly, the findings demonstrated that loneliness was positively associated with depression. Secondly, the results showed that emotional intelligence moderated the relationship between loneliness and depression, indicating that high emotional intelligence functioned as a buffer for the contribution of loneliness to depression. In contrast, higher levels of loneliness were significantly associated with a greater risk of depression among emerging adults with low or moderate emotional intelligence. Lastly, gender did not moderate the moderating effect of emotional intelligence on the relationship between loneliness and depression. This study concluded with limitations, recommendations for future research, and practical and theoretical implications for practitioners.

The mediating effects of sleep quality in the relationship between loneliness and depression among middle-aged and older adults

Loneliness has long been recognized as a key predictor of depression in older adults, and both are related to sleep quality. However, to this day, less is known about whether sleep quality mediates their relationship. This study aimed to examine the relationship between loneliness, sleep quality, and depressive symptoms, and to further explore whether sleep quality mediates the relationship between loneliness and depressive symptoms. Using the random cluster sampling method, 1016 permanent residents aged 45 and above in Ankang City, Shaanxi Province were selected. The relationship between loneliness, sleep quality, and depressive symptoms was analyzed using binary logistic regression, and the mediating role of sleep quality between loneliness and depressive symptoms was analyzed using the PROCESS macro in SPSS 25.0 software. The average age of the participants in this study was 60.39 ± 8.50. Regression analyses showed that individuals with loneliness (OR 7.161, 95%CI: 4.889-10.490, P < 0.001) and those with poor sleep quality (OR 4.777, 95%CI: 3.301-6.913, P < 0.001) were more likely to experience depressive symptoms than individuals without loneliness and with good sleep quality. This study also found a significant mediating effect of sleep quality between loneliness and depressive symptoms [effect value = 0.066, bootstrap 95% CI: (0.037, 0.093)] with an effect size of 13.31%. Loneliness may lead to reduced sleep quality in individuals, which in turn may lead to or exacerbate depressive symptoms. Therefore, this study highlights the importance of assessing and improving sleep quality in lonely people.

Is self-disgust an implicit or explicit emotional schema?

Self-disgust, a negative self-conscious emotional schema that is associated with mental health difficulties in both clinical and non-clinical populations, is typically assessed with self-reported measures that target physical and behavioural aspects of the self. The aim of the present research was to develop and validate a novel implicit self-disgust measure (ISDM) using an Implicit Association Task (IAT) paradigm, across three studies. Study 1 developed a list of disgust-related and positive words that were rated for emotional valence and arousal and informed the content of the ISDM. Study 2 developed and examined the ISDM using the single-target IAT in a non-clinical population and showed that scores in the ISDM were significantly associated with self-reported self-disgust. Study 3 partly replicated the findings of Study 2 among participants with trauma-related experiences and following a mood induction paradigm, showing a significant association between the ISDM and the physical aspect of self-reported self-disgust. These findings are significant because they have implications about the automaticity of self-disgust in people with traumatic experiences which can further inform clinical practice and interventions targeting self-disgust.

Association between childhood trauma and social anxiety in adolescents: The mediating role of self-compassion and loneliness

BACKGROUND

Previous studies have shown a correlation between childhood trauma and social anxiety. However, the underlying mechanism of this association is not well understood.

OBJECTIVE

The aim of this study was to examine the relationship between childhood trauma and social anxiety in adolescents, and to explore the mediating role of self-compassion and loneliness.

PARTICIPANTS AND SETTING

In total 1309 adolescents (531 of whom were female) were recruited, and their mean age was 15.4 ± 2.30 years.

METHODS

Participants completed the Adolescent Social Anxiety Scale, Childhood Trauma Questionnaire Short Form, Self-Compassion Scale, and University of California, Los Angeles Loneliness Scale. Pearson correlation analysis was conducted to investigate the relationships among childhood trauma, self-compassion, loneliness, and social anxiety. The PROCESS Macro Model 80 was used for regression analysis to explore the mediating effects of self-compassion and loneliness on the relationship between childhood trauma and social anxiety.

RESULTS

After controlling for the influence of gender and parental marital status, self-compassion mediated the association between childhood trauma and social anxiety, in which positive self-compassion alleviated the relationship between childhood trauma and social anxiety, while negative self-compassion aggravated the relationship between childhood trauma and social anxiety. Furthermore, self-compassion and loneliness chain-mediated the relationship between childhood trauma and social anxiety.

CONCLUSION

These results offer theoretical support for the research and intervention of adolescents' social anxiety, and are crucial for developing adolescents' mental health education and promoting interpersonal communication.

Loneliness is associated with unhealthful dietary behaviors and physical inactivity among US college students

Objective: To evaluate dietary and physical activity behavior in relation to loneliness among college students. Participants: Three-hundred forty-six incoming first-year students in Fall 2019 at a large state University in the US. Methods: Students completed online surveys in Fall 2019. Multivariable regression analyses were used to model associations of health behaviors with loneliness, adjusting for gender and body mass index (BMI). Results: Two-hundred sixty-four students were included in this analysis. Students in loneliness score ranges of 4-6 and 7-9 have higher fat diet than students in score range of 10-12 (p = .007). Sedentary (19.2%) and low active (53.8%) behaviors were more frequent in students reporting high loneliness than those reporting low loneliness (13.8%, 36.7%, respectively) (p = .006). Conclusions: In this sample of college students, loneliness was related to altered diet quality and physical inactivity. Interventions to reduce loneliness may have a positive effect on health promotion in this population.

An Investigation of the Mediating Roles of Emotion Regulation Difficulties, Distress Tolerance, Self-Compassion, and Self-Disgust in the Association Between Childhood Trauma and Nonsuicidal Self-Injury

OBJECTIVE

Childhood maltreatment has been associated as a risk factor with the development of nonsuicidal self-injury (NSSI), with difficulty in emotion regulation explaining the association. However, little is known about the potential factors that make some individuals with maltreatment history more vulnerable to difficulties in emotion regulation and, in turn, engage in NSSI. The current study aimed to examine the roles of distress tolerance, self-compassion, and self-disgust in the association between childhood maltreatment types and emotion regulation difficulty, which was expected to predict NSSI.

METHOD

The sample included 397 university students between the ages of 18 and 30. Participants completed self-report scales assessing childhood maltreatment, emotion regulation difficulty, distress tolerance, self-compassion, self-disgust, and NSSI using the paper-pencil and online methods. The mediation model suggested for the association between childhood maltreatment types and NSSI was tested using path analysis.

RESULTS

Low distress tolerance, low self-compassion, high self-disgust, and resulting high emotion regulation difficulty mediated the indirect effect of emotional neglect on NSSI.

CONCLUSION

The current study sheds light on various factors in the development and maintenance of NSSI and reveals three developmental pathways from emotional neglect in childhood to engaging in NSSI.HIGHLIGHTSEmotional neglect may be a distal risk factor for nonsuicidal self-injury (NSSI).Low distress tolerance and self-compassion and high self-disgust may increase the risk of NSSI.Emotion regulation difficulty may make people engage in NSSI to regulate emotions.

A preliminary study on the neurocognitive deficits associated with loneliness in young adults

The experience of loneliness is universal and may have an adverse effect on neurocognitive functioning even at a younger age. Using a comprehensive neurocognitive functioning test (NCFT) battery, we examined the possible negative effects of loneliness on neurocognitive functioning in young adults. The high-loneliness and low-loneliness groups were screened using the UCLA Loneliness Scale v. 3, and measures pertaining to the domains of intelligence, attention, memory, executive function, and psychomotor functioning were tested and compared. As depression and anxiety were significantly higher in the high-loneliness group, an analysis of covariance was conducted. As a result, the high-loneliness group showed significantly poor performance on measures of executive function and attention prior to controlling for depression and anxiety, and executive function retained its significance even after controlling for these variables. Additional analysis showed that depression and anxiety did not significantly mediate the relationship between loneliness and neurocognitive functioning. Such results suggest that loneliness is likely to negatively affect executive functioning and attention in early adulthood and then progressively spread to other domains of cognitive functioning, as reported in the older adult population. The limitations and implications of the present study were considered and addressed.

Development of depression detection algorithm using text scripts of routine psychiatric interview

Background

A psychiatric interview is one of the important procedures in diagnosing psychiatric disorders. Through this interview, psychiatrists listen to the patient's medical history and major complaints, check their emotional state, and obtain clues for clinical diagnosis. Although there have been attempts to diagnose a specific mental disorder from a short doctor-patient conversation, there has been no attempt to classify the patient's emotional state based on the text scripts from a formal interview of more than 30 min and use it to diagnose depression. This study aimed to utilize the existing machine learning algorithm in diagnosing depression using the transcripts of one-on-one interviews between psychiatrists and depressed patients.

Methods

Seventy-seven clinical patients [with depression (n = 60); without depression (n = 17)] with a prior psychiatric diagnosis history participated in this study. The study was conducted with 24 male and 53 female subjects with the mean age of 33.8 (± 3.0). Psychiatrists conducted a conversational interview with each patient that lasted at least 30 min. All interviews with the subjects between August 2021 and November 2022 were recorded and transcribed into text scripts, and a text emotion recognition module was used to indicate the subject's representative emotions of each sentence. A machine learning algorithm discriminates patients with depression and those without depression based on text scripts.

Results

A machine learning model classified text scripts from depressive patients with non-depressive ones with an acceptable accuracy rate (AUC of 0.85). The distribution of emotions (surprise, fear, anger, love, sadness, disgust, neutral, and happiness) was significantly different between patients with depression and those without depression (p < 0.001), and the most contributing emotion in classifying the two groups was disgust (p < 0.001).

Conclusion

This is a qualitative and retrospective study to develop a tool to detect depression against patients without depression based on the text scripts of psychiatric interview, suggesting a novel and practical approach to understand the emotional characteristics of depression patients and to use them to detect the diagnosis of depression based on machine learning methods. This model could assist psychiatrists in clinical settings who conduct routine conversations with patients using text transcripts of the interviews.

Frontal lobe-related cognition in the context of self-disgust

Self- disgust is an adverse self-conscious emotion that plays an important role in psychopathology and well-being. However, self-disgust has received little attention in the emotion literature, therefore our understanding of the processes underlying the experience of self-disgust is relatively scarce, although neuropsychological and neuroimaging studies support the idea that this emotion may heavily rely on frontal lobe-related cognition. To test this hypothesis, in two studies we investigated the relationship between state and trait levels of self-disgust, cognition and emotion regulation in healthy adults. Specifically, in Study 1 we tested the hypothesis that emotion regulation strategies (avoidance, suppression, and cognitive reappraisal) mediate the relationship between inhibition ability and state and trait levels of self-disgust. In Study 2, we followed a more comprehensive approach to test the hypothesis that frontal lobe-related cognitive processes (updating, Theory of Mind-ToM-, and self-attention) are closely related to the experience of self-disgust in healthy adults. Overall, across these studies, we found evidence to support the idea that inhibition ability and ToM may play a role in the experience of state and trait self-disgust, respectively. However, we did not find consistent evidence across the two studies to support the notion held in the literature that the experience of self- conscious emotions, in this case self-disgust, is heavily dependent on frontal lobe-related cognition.

Prevalence and Predictors of Loneliness Among Youth During the Time of COVID-19: A Multinational Study

BACKGROUND

Given the restrictions associated with COVID-19, feelings of loneliness among youth may increase.

AIMS

The aims of the current study were to assess the prevalence of loneliness among young people at the time of COVID-19 and to identify whether selected variables related to the pandemic predicted the level of loneliness.

METHOD

A cross-sectional study using WhatsApp and Facebook social media platforms was conducted to survey 1,057 young people aged 15 to 24 years from six Middle Eastern countries. Participants completed survey items including demographic and COVID-19-related questions; the Depression, Anxiety and Stress Scale (DASS); the Satisfaction With Life Scale (SWLS); and the UCLA Loneliness Scale.

RESULTS

The prevalence of experienced loneliness was 1 (0.1%), 625 (59.1%), 429 (40.6%), and 2 (0.2%), reflecting low, moderate, moderately high, and high experiences for loneliness, respectively. History of depression or anxiety, being dissatisfied with life, and having depression at the time of COVID-19 were significant predictors of loneliness among youth. The model was significant (F = 44.95, p < .05) and accounted for 29.8% of the variance in UCLA Loneliness Scale scores.

CONCLUSIONS

We found that the high prevalence rate of loneliness during the COVID-19 pandemic was correlated with depression and impaired life satisfaction among Middle Eastern youth. Thus, special attention and interventional action plans need to be developed taking into consideration the youths' special situation during COVID-19.

Prevalence and Psychiatric Correlates of Illicit Substance Use in UK Undergraduate Students

This study examined the prevalence of illegal drug use in UK students and motivators behind such behavior. Additionally, we explored possible relationships between substance use, psychosocial motivators, and psychiatric distress. A group (n = 543) of students completed online measures of substance use, anxiety, depression, perceived stress, and insomnia. A series of reasons behind their use were ranked based on importance. Reported cannabis, cocaine, nitrous oxide, ketamine, and MDMA use were most prevalent based on lifetime, past year, and month assessments. The experience of anxiety, depression, perceived stress, and insomnia were related to increased reports of substance use. Poor self-confidence and self-medication were key motivators of illicit drug use in those presenting greater psychiatric distress. These outcomes add to the sparse body of literature concerning illicit substance use in relation to psychiatric distress amongst UK students. Furthermore, we provided novel insight into the psychosocial motivators of such use.

Disgust as a transdiagnostic index of mental illness: A narrative review of clinical populations

Disgust is a basic emotion of rejection, providing an ancestral defensive mechanism against illness. Based on research that documents altered experiences of disgust across several psychopathological conditions, we conducted a narrative review to address the hypothesis that altered disgust may serve as a transdiagnostic index of mental illness. Our synthesis of the literature from past decades suggests that, compared to healthy populations, patients with mental disorders exhibit abnormal processing of disgust in at least one of the analyzed dimensions. We also outline evidence of alterations in brain areas relevant to disgust processing, such as the insula and the interconnected limbic network. Overall, we provide preliminary support for the hypothesis that altered disgust processing may serve as a transdiagnostic index of mental illness.

The Development of Disgust and Its Relationship to Adolescent Psychosocial Functioning

Experiences of excessive disgust have been implicated in several psychopathologies. Research, however, has rarely examined disgust and its role in psychosocial functioning from a developmental standpoint. This study examines the relationship between disgust expression in early life and subsequent adolescent psychosocial functioning. Data from 165 children were collected as part of a longitudinal study. Disgust propensity in infancy and childhood was assessed using a facial expressivity task and food aversion task, respectively. Adolescent psychosocial functioning was measured through several self-report measures. Results suggest that there exists a degree of consistency in disgust expression within the first year of life, and that childhood disgust propensity may be related to impairment in early adolescent psychosocial functioning. These findings highlight the potential importance of identifying early disgust expression as a marker for later psychopathology.

Loneliness is not a homogeneous experience: An empirical analysis of adaptive and maladaptive forms of loneliness in the UK

Understanding loneliness is pivotal to informing relevant evidence-based preventive interventions. The present study examined the prevalence of loneliness in the UK, during the COVID-19 pandemic, and the association between loneliness, mental health outcomes, and risk and protective factors for loneliness, after controlling for the effects of social isolation. It was estimated that 18.1% of the population in our study experienced moderately high to very high loneliness. We also found that loneliness was positively associated with self-disgust and social inhibition, and negatively associated with trait optimism and hope. Cluster analysis indicated that two distinct groups emerged among those experiencing higher levels of loneliness: "adaptive" and "maladaptive" loneliness groups. The maladaptive loneliness group displayed psychological characteristics like self-disgust and social inhibition including symptoms of depression and anxiety that can potentially undermine their ability to connect with others and form meaningful social relationships. These findings suggest that not all people experience loneliness in the same way. It is possible that a one-size-fit-all approach to reducing loneliness, may be less effective because it does not take into account the differential psychological profiles and characteristics of lonely people, relevant to their capacity to connect with others.

The harms of medicalisation: intersex, loneliness and abandonment

This article develops loneliness as a political and social justice issue by illustrating the harmful personal and social consequences of the medical jurisdiction over and constitution of variations in sex characteristics. Whilst connections between loneliness, health and illness have been well established, this work customarily identifies the ways illness can lead to, or be caused by, loneliness. Instead, I provide an account of the central role of medicalisation and medical management in producing loneliness. By doing so, I underline the imperative for medical practice to consider its influence upon social and personal, as well as physical, wellbeing. Drawing on stories shared through solicited diaries followed by in-depth interviews with seven people with sex variations and two parents in the UK, I show how accounts of loneliness help to illuminate the violence of abandonment, silencing and marginalisation that often goes unheard, together with hidden or normalised systems of harm.

Building on concepts of ethical loneliness and ontological loneliness, I show how structural violations operate to injure trust and self-worth, leading to social unease. I argue for the importance of people with sex variations finding sites of comfort and acceptance, but note the ways that some forms of medicalisation can inhibit alliances and community formation, despite diagnoses also carrying the potential to facilitate informal support structures and collective identities. By bringing together intersex studies with discourses of loneliness, I develop a better understanding of loneliness as a product of social and systemic violence, and the ways in which medical discourses tie in with larger structures of oppression, coercion and control. This article concludes by underlining the need for structural change in our approach to and understanding of sex variations, and with a call for us to become more attentive to these stories of medical harm, to ensure that they are heard and to seek necessary justice.

Self-disgust as a potential mechanism underlying the association between body image disturbance and suicidal thoughts and behaviours

This study examined whether self-disgust added incremental variance to and mediated the multivariate association between measures of body image disturbance and suicidal thoughts and behaviours. We hypothesized that self-disgust would be associated with suicidal ideation above the effects of body image disturbance, and that self-disgust would mediate the relationship between body image disturbance and suicidal ideation. A total of N=728 participants completed The Body Image Disturbance Questionnaire, The Self-Disgust Scale, and the Suicidal Behaviours Questionnaire-Revised. Suicidality was significantly related to increased levels of self-disgust and body image disturbance, whereas self-disgust was associated with greater body image disturbance. Linear regression analysis showed that self-disgust was associated with suicidal thoughts and behaviours, over and above the effects of body image disturbance. Multiple mediation modelling further showed that self-disgust mediated the relationship between body image disturbance and suicidal thoughts and behaviours. Our findings highlight the role of self-disgust in the context of body image disturbance and support the notion that body image disturbance is associated with aversive self-conscious emotions. Interventions aiming to reduce the risk of suicidality in people with body image disturbance may address self-disgust and negative self-conscious emotions.

Conditional Process Modeling of the Relationship Among Self-Reliance, Loneliness, and Depressive Symptoms, and the Moderating Effect of Feeling Understood

ABSTRACT

Self-reliance features as one of the notable male norms espoused by traditional masculine socialization. Strict adherence to a self-reliant attitude has been found to confer risk for depression and suicidality among men. Yet, little research has investigated the factors that may contribute to self-reliance having a negative impact for men. Using data from a large sample of Canadian men (N = 530), the present study examined the association between self-reliance and depression, while also assessing the roles of loneliness and not feeling understood as contributing factors in this process. Findings indicated that the moderated mediation model was significant, pointing to loneliness as a significant mediator in the association between self-reliance and depression. Furthermore, the findings revealed that not feeling understood moderated the relationship between self-reliance and loneliness, indicating that this association applies mainly to those men who do not feel understood by at least one important person in their life.

Effects of Self-Esteem on Self-Viewing: An Eye-Tracking Investigation on Mirror Gazing

While some people enjoy looking at their faces in the mirror, others experience emotional distress. Despite these individual differences concerning self-viewing in the mirror, systematic investigations on this topic have not been conducted so far. The present eye-tracking study examined whether personality traits (self-esteem, narcissism propensity, self-disgust) are associated with gaze behavior (gaze duration, fixation count) during free mirror viewing of one's face. Sixty-eight adults (mean age = 23.5 years; 39 females, 29 males) viewed their faces in the mirror and watched a video of an unknown person matched for gender and age (control condition) for 90 s each. The computed regression analysis showed that higher self-esteem was associated with a shorter gaze duration for both self-face and other-face. This effect may reflect a less critical evaluation of the faces.

Self-disgust and disgust sensitivity are increased in anorexia nervosa inpatients, but only self-disgust mediates between comorbid and core psychopathology

OBJECTIVE

The possible role of abnormal disgust processing in the development and course of anorexia nervosa (AN) has been emphasized in theoretical models and research. However, disgust toward external stimuli and self-disgust have not yet been investigated together in a clinical sample of AN patients. Therefore, the purpose of the study was to measure these constructs and examine their role in shaping eating pathology in AN patients and healthy controls (HCs), considering comorbid depressive and anxiety psychopathology. The study also aimed at testing the possible mediational roles of both disgust types in the associations between comorbid psychopathology and eating disorders (EDs) characteristics.

METHOD

Altogether, 63 inpatients with AN and 57 HCs partook in the study. Participants completed the Eating Disorder Inventory-3, State-Trait Anxiety Inventory, Beck Depression Inventory-II, Disgust Scale-Revised and Self-Disgust Scale.

RESULTS

AN patients manifested higher self-disgust and disgust sensitivity than HCs. In addition, self-disgust predicted the severity of EDs characteristics and mediated the links of depressive symptoms and trait anxiety with EDs characteristics in both groups.

DISCUSSION

Our findings imply the putative role of self-disgust in the development of EDs psychopathology in HCs and in its maintenance in AN patients.

Depression and loneliness may have a direct connection without mediating factors

PURPOSE OF THE ARTICLE

There is growing interest in loneliness and its various adverse effects on mental and physical health. While depression is one of the adverse health effects associated with loneliness, there have been some limitations in previous studies: 1) Research has mostly been carried out either in depressed patient samples or in general population samples with depressive symptoms as an outcome, 2) the follow-up times have been rather short, and 3) the mechanisms through which loneliness associates with depression are still unclear.

MATERIALS AND METHODS

We examined the association between loneliness and incident depression and possible mechanisms underlying this association in a population-based sample of middle-aged men (N = 2339; mean age 53; mean follow-up time 23.5 years). The association between loneliness and depression was explored with Cox proportional hazard analysis, and mediation analyses were performed with the PROCESS macro for SPSS. We used 13 health and lifestyle-related variables as covariates for adjustments in multivariate models and as mediators in simple mediation models.

RESULTS

Those with depression as an outcome (n = 99) had significantly higher loneliness scale scores at baseline, and baseline loneliness was associated with depression, despite adjustments for potential confounding factors. No mediating factors were observed.

CONCLUSIONS

There was a strong direct association between loneliness and the incidence of depression. Based on our results, we encourage future researchers to look for possible mediators in wider range of variables.

The Impact of a Digital Intervention (Happify) on Loneliness During COVID-19: Qualitative Focus Group

BACKGROUND

Loneliness is a growing area of concern, attracting attention as a public health concern due to its association with a variety of psychological and physical health problems. However, interventions targeting loneliness are less common than interventions for other mental health problems, such as depression and anxiety, and existing interventions focus primarily on building social skills and increasing opportunities for social interaction despite research suggesting these techniques are not the most effective. Furthermore, although there is an increasing need for scalable and convenient interventions, digital interventions for loneliness are even less common.

OBJECTIVE

Using a qualitative approach, we explore how adults (18-64 years of age) who express wanting to be more connected to others experience loneliness and react to a digital mental health intervention targeting loneliness.

METHODS

A total of 11 participants were recruited from a pilot randomized controlled trial exploring the impact of a digital mental health intervention, Happify Health, on loneliness among adults aged 18-64 years who indicated wanting to feel more connected to others when signing up for the platform. Participants were invited to participate in a 3-day asynchronous focus group about their experiences with loneliness, with Happify Health, and with social distancing during the COVID-19 pandemic. All 11 participants completed the focus group in May 2020.

RESULTS

Participants' responses were coded using thematic analysis, which led to identifying five themes, each with separate subthemes, that could be applied across the 3-day focus group: loneliness, relationships, social distancing, skill acquisition, and coping. Overall, we observed variability across participants in terms of the source of their loneliness, their perceptions of their social connections, and their motivation to reduce feelings of loneliness; however, participants commonly referred to negative self-perceptions as a cause or consequence of loneliness. Participants also varied in the extent to which they felt social distancing increased or decreased feelings of loneliness. In regard to the intervention, participants showed evidence of adopting skills they used to address their loneliness, particularly mindfulness and gratitude, and then using these skills to shift toward more active coping strategies following the intervention, including during the COVID-19 pandemic.

CONCLUSIONS

The heterogeneity in participants' experiences with loneliness described during this focus group emphasizes the subjective and complex nature of loneliness. This highlights the importance of developing loneliness interventions that use a variety of strategies, including both direct and indirect strategies for reducing loneliness. However, based on our data, a key component to loneliness interventions is incorporating strategies for addressing underlying negative self-perceptions that stem from, but also contribute to, loneliness. This data also provides preliminary evidence that digital platforms may be an effective tool for disseminating loneliness interventions while providing the added benefit of offering a productive distraction when feeling lonely.

Psychosocial impact of the COVID-19 pandemic: a cross-sectional study of online help-seeking Canadian men

Purpose: The COVID-19 pandemic has had a profound impact on the lives of men. The present study investigated psychosocial impacts of the COVID-19 pandemic on a help-seeking sample of Canadian men, focusing on diverse aspects of their psychosocial well-being.Methods: A cross-sectional, open survey study design was used. Canadian adult men who were visiting an eHealth depression resource (HeadsUpGuys.org) were recruited to complete an online survey. Descriptive statistics, including means and standard deviations for continuous variables and frequency and percentages for categorical variables, were used to summarize survey responses. Regression analysis was utilized to identify factors associated with various mental health indicators (anxiety, depression, fear of COVID-19, suicidality). The Patient Health Questionnaire-4, Fear of COVID-19 Scale, and item 9 (suicidality item) from the Patient Health Questionnaire-9 were used to assess the mental health indicators.Results: A total of 434 men completed the study. Most respondents (79.3%; N = 344) indicated that their mental health was negatively affected by COVID-19, and two-thirds (65.5%; N = 284) conveyed that government-imposed physical distancing measures had negatively affected their mental health. Half the sample (51.2%; N = 222) reported at least moderate financial stress due to COVID-19. Nearly a third of respondents (31.1%; N = 135) reported that their current living situation has had a considerable or severe negative impact on their mental health since COVID-19. About two-fifths (37.7%; N = 94) of men felt that COVID-19 has had a negative impact on their relationship with their intimate partner. Nearly a third of respondents who were in a relationship (30.9%; N = 77) reported that they engaged in some type of abuse (primarily verbal abuse, 22.9%; N = 57) toward their intimate partner during COVID-19, and more than a quarter (27.3%; N = 68) reported being abused by their intimate partner (also primarily verbal abuse, 22.5%; N = 56). Just under half (42.2%; N = 183) of the respondents indicated experiencing suicidal ideation.Conclusion: These findings can help inform providers of health services to Canadian men, as well as policies that will be implemented during subsequent waves of COVID-19 or during future infectious outbreaks.

Self-Disgust Is Associated With Loneliness, Mental Health Difficulties, and Eye-Gaze Avoidance in War Veterans With PTSD

In the present study, we examined, for the first time, the association between self-disgust, loneliness, and mental health difficulties in war veterans diagnosed with PTSD. For this purpose, we used a mixed methods design, incorporating surveys and a novel eye-tracking paradigm, and compared the findings from the PTSD veteran group (n = 19) to those from a general population group (n = 22). Our results showed that the PTSD veteran group reported almost three times higher scores in self-disgust, and significantly higher scores in loneliness and mental health difficulties (anxiety and depression), compared to the general population. Furthermore, self-disgust mediated the association between loneliness and anxiety symptoms in both groups. The results from the eye-tracking paradigm further showed that veterans with PTSD displayed a self-avoidance gaze pattern, by looking significantly more toward pictures of faces of unknown others and away from their own face—a pattern that was not replicated in the general population group. Higher self-disgust scores were significantly associated with longer total gaze to the pictures of others (vs. the self). Our findings have implications for the role of self-disgust in the mental health of war veterans.

Distress Concealment and Depression Symptoms in a National Sample of Canadian Men: Feeling Understood and Loneliness as Sequential Mediators

Men's tendency to conceal their distress has been linked with increased depressive symptoms. Although interpersonal connectedness has been associated with distress concealment and depression, it is unclear how connectedness mediates this association. The aim of the present study was to examine the mediating effects of feeling understood and loneliness-two facets of interpersonal connectedness-in the association between distress concealment and depressive symptoms in men. A sample of 530 Canadian men was selected based on age- and region-stratification that reflects the national population. Participants completed measures of depression symptoms, distress concealment, loneliness, and feeling understood. Mediation analyses were conducted. Results supported a sequential mediation model: concealing distress was associated with not feeling understood, not feeling understood was associated with loneliness, and loneliness was associated with depressive symptoms. These findings shed light on how distress concealment is associated with depressive symptoms among men. Implications for practice and theory are discussed.

Questionnaire for the Assessment of Self-Disgust: The psychometric testing among mental disorders in China

Research on self-disgust is relevant to psychopathologic tendencies because it has been shown to play a critical role in several mental disorders. Examining self-disgust and exploring its role in mental health are significant goals. The purpose of this study was to translate the Questionnaire for the Assessment of Self-Disgust (QASD) into Chinese and evaluate its validity and reliability. The translation and validation of the QASD were guided by the World Health Organization's Process of Translation and Adaptation of Instruments. Three phases were undertaken: (a) professional translation and expert panel review, (b) pretesting, and (c) psychometric evaluation. The psychometric evaluation was tested among 1,068 patients who were recruited from two psychiatric hospitals and three psychological clinics of tertiary hospitals. In this study, multigroup confirmatory factor analysis (CFA) supported the two-factor structure of the original QASD construct. Measurement invariance showed that the QASD is invariant across the patients with heterogeneous mental health diagnoses. The correlation of QASD with the Self-Esteem Scale (SES) and the Trait Anger Scale (TAS) showed that it has good convergent validity and discriminative validity. Internal consistency and test-retest yielded acceptable results. Thus, the findings suggest that the Chinese version of the QASD is a reliable and valid instrument with adequate psychometric properties for assessment of self-disgust among patients with mental disorders in China.

Self-disgust, loneliness and mental health outcomes in older adults: An eye-tracking study

BACKGROUND

Self-disgust has been associated with loneliness and mental health difficulties in clinical and non-clinical populations, but there is limited research on the role of self-disgust in loneliness and mental health outcomes in older adults.

METHODS

In Study 1 (N = 102; M age = 68.4 years, SD = 10.9, 68% females) we used a cross-sectional survey to explore the association between loneliness, self-disgust and mental health outcomes. In Study 2 (N = 80; M age = 68.8 years, SD = 11.4, 57% females) we used eye-tracking to investigate attentional vigilance, maintenance and avoidance in individuals with high (vs. low) self-disgust.

RESULTS

In study 1 we found that self-disgust mediated the associations of loneliness with anxiety and depressive symptoms, and in study 2 it was demonstrated that older adults with high (vs. low) self-disgust displayed attentional avoidance to their own faces, compared to the faces of unknown others, a process that may perpetuate loneliness.

LIMITATIONS

The cross-sectional design used in Study 1 limits our potential to make causal inferences. Additionally, both studies included a wide age range of older adults.

CONCLUSIONS

Our findings are novel and highlight the importance of self-disgust experiences in the context of loneliness and mental health outcomes in older adults. Implications for practice and interventions against loneliness in this age group are discussed.

Depression mediates cutaneous body image and facial appearance dissatisfaction in insomnia

This study examined the relationship between dissatisfaction with cutaneous body image and facial appearance with symptoms of insomnia whilst incorporating the mediating role of anxiety and/or depression after accounting for co-morbid sleep disorder symptoms. Participants (n = 241) completed online measures assessing insomnia symptoms, anxiety and depression symptoms, and satisfaction with cutaneous body image and facial appearance. Symptoms of insomnia were independently related to greater dissatisfaction with cutaneous body image and facial appearance in univariate analyses. However, linear regression analyses determined these relationships to be partially mediated by depression, but not anxiety. Expanding on prior research, these findings suggest that whilst increased symptoms of insomnia may influence dissatisfaction with cutaneous and facial features, these relationships may be partially attributed to the experience of depressive symptoms often co-morbid with both insomnia and dermatological complaints. Treatment approaches for individuals with insomnia may benefit from targeting and improving negatively appraised aspects of physical self-perception.

Impact of perceived social support on depression in Chinese rural-to-urban migrants: The mediating effects of loneliness and resilience

The present study aimed to examine whether loneliness and resilience played the roles of mediators on the relationship between perceived social support and depression. A total of 712 Chinese rural-to-urban migrants from Nanjing, who were measured with perceived social support, resilience, loneliness, and depression, participated in the study. Results indicated that perceived social support and resilience were negatively associated with depression. Loneliness was a significant and negative predictor for depression. In addition, we also revealed that resilience and loneliness partially mediated the relationship between perceived social support and depression. These findings might develop a better understanding of depression in the course of migration.
