The Association Between Child Maltreatment and Loneliness Across the Lifespan: A Systematic Review and Multilevel Meta-Analysis

The Path to Loneliness for Psychiatric Patients: A Qualitative Study of a Journey Marked by Pain, Hopelessness, Prosocial Signaling Deficits, and Coping Strategies That Are Not Effective

Enduring loneliness has serious physical and mental health implications. Patients with mental health problems are at risk of experiencing problems related to loneliness. Therefore, it is important to increase knowledge about how loneliness is experienced and managed in this particular group. The aim of the study was to explore (1) psychiatric patients' experiences of different forms of loneliness, (2) associated problems, including difficulties with prosocial signaling, and (3) strategies used to combat loneliness, to better understand how loneliness affects psychiatric patients and how patients manage their loneliness. A total of 110 psychiatric patients were recruited at eight outpatient clinics in Region Stockholm for a larger study of loneliness. The first fifteen patients who also agreed to participate in the present substudy were invited to meet a trainee psychologist who conducted a semi-structured interview. A reflexive thematic analysis with a codebook approach was used to analyze the transcripts. The described experiences of loneliness were primarily examples of social and emotional loneliness with one prominent theme: "Hopelessly lonely". Associated problems were summarized in two themes: "The inevitable road to loneliness" and "Social signals are confusing and push others away". Regarding patients' strategies for combating loneliness, one theme emerged: "Using strategies that focus on the current moment". The results also included a total of sixteen subthemes. Loneliness was described as something painful that is inevitable and unchangeable, with a self-reinforcing loneliness loop leading to social and emotional loneliness, and as something that is intertwined with mental health problems. These results are in accordance with research. In addition, patients described a variety of prosocial signaling deficits and feelings of being disconnected from others. They also reported using strategies that primarily alleviated their immediate suffering when they were alone, rather than focusing on approaches with long-term effects on reducing loneliness, such as participating in social activities combined with effective social signaling. Future research should investigate whether increased awareness of social signaling, as well as social activities combined with improved prosocial signaling and strengthened self-belief, would constitute effective steps for patients to combat enduring loneliness. It also seems important to help patients reduce hopelessness related to loneliness.

Rebuilding what has been ruined: Navigating the impacts of child maltreatment for romantic relationships and friendships in emerging adulthood

BACKGROUND

Child maltreatment (CM) can contribute to attachment insecurity, creating challenges to building supportive relationships that support growth and resilience in adulthood. Studies have focused on understanding how CM survivors adapt to the impacts of CM for their family-of-origin relationships or parenting, but fewer have explored chosen relationships.

OBJECTIVE

This study seeks to fill this gap by exploring how emerging adults with CM histories subjectively experience, understand, and cope with the impacts of CM for their friendships and romantic relationships.

PARTICIPANTS AND SETTING

The sample consisted of 23 emerging adults (18 to 25 years old) with a CM history, living in Canada.

METHODS

Participants were invited for semi-structured interviews documenting CM and interpersonal experiences. A hybrid thematic analysis was conducted to identify themes and subthemes.

RESULTS

Three overarching themes emerged, each dealing with broken trust: 1) Internal experiences stemming from CM preventing trust, 2) Coping with broken trust by protecting oneself, and 3) Learning how to build trust in others and themselves.

CONCLUSIONS

Emerging adults described interpersonal challenges stemming from broken trust caused by CM and maintained by internal experiences of fear, longing, guilt, and shame. Coping through avoidance, isolation, and dominance over others further maintained distrust. However, emerging adults undertook a learning process, involving attempts to engage with others, recognize patterns of abuse, and practice behavioural changes. Future research should explore the role of chosen relationships, especially friends, in mental health interventions and efforts to foster greater social support and stronger community among emerging adults with CM.

The longitudinal association between adverse childhood experiences (ACEs) with transient and chronic loneliness among older adults

OBJECTIVES

Determine whether exposure to adverse childhood experiences (ACEs) confer a greater vulnerability to chronic and/or transient loneliness in older age, and whether specific types of ACEs are more strongly associated with chronic and/or transient loneliness.

METHOD

Participants (N = 1532) were drawn from the English Longitudinal Study of Ageing, a nationally representative sample of UK adults aged 50 years and over. Multinomial logistic regressions adjusted for sociodemographic and health-related covariates were used to determine how ACEs related to chronic and transient loneliness and which subtypes of ACEs (dysfunction, threat, or loss-based) are most associated with chronic and/or transient loneliness.

RESULTS

Experiencing 1 ACE (adjusted odds ratio [AOR] 1.43 [95% confidence interval [CI] 1.01-2.02]) or 2 or more ACEs (AOR 1.63 [95% CI 1.09-2.42]) was associated with a greater likelihood of experiencing chronic loneliness when compared to people who never experienced ACEs. There was no association between number of ACEs with transient loneliness. Dysfunction-based ACEs had a fully adjusted association with chronic loneliness (AOR 1.57 [95% CI 1.12-2.20]) and transient loneliness (AOR 1.58 [95% CI 1.12-2.23]).

CONCLUSION

This research suggests that ACEs are associated with a greater likelihood of experiencing chronic loneliness in older age. More specifically, dysfunction-based ACEs (linked to parental conflict, separation, mental illness, or substance use) were particularly associated with loneliness in older age. These findings suggest that it is important to consider the role of early life adversity when developing interventions to tackle loneliness in older age.

A systematic review of longitudinal risk and protective factors for loneliness in youth

To effectively tackle loneliness in youth, prevention and intervention strategies should be based on solid evidence regarding risk and protective factors in this age group. This systematic literature review identifies and narratively synthesizes longitudinal studies of risk and protective factors for loneliness in children and adolescents aged below 25 years. A systematic literature search was conducted in October 2023 using PsycINFO and MEDLINE, resulting in n = 398 articles, with n = 105 articles meeting the inclusion criteria. The examined factors included demographic (e.g., gender), socioeconomic (e.g., income sufficiency), social (e.g., peer acceptance), mental health (e.g., depression), physical health (e.g., disabilities), health behavior (e.g., sport participation), and psychological factors (e.g., shyness). Additionally, adverse childhood experiences (e.g., child maltreatment) and environmental factors (e.g., neighborhood characteristics) were investigated. Despite the wide range of potential risk and protective factors examined, relatively few studies provided strong evidence for a prospective association with loneliness. Risk factors that were consistently identified across multiple longitudinal studies included low peer acceptance and peer victimization, depression, social anxiety, internalizing symptoms, low self-esteem, shyness, and neuroticism. Additional replication is required to evaluate factors that have shown significant associations with loneliness in only a limited number of longitudinal studies (e.g., aggression).

You say it's not me: the influence of offering external explanations of rejection and acceptance behavior on the perception of benevolence in borderline personality disorder

BACKGROUND

Interpersonal impairments in patients diagnosed with borderline personality disorder (BPD) are characterized by the fear of being rejected and high levels of loneliness. Potential underlying factors are alterations in the processing of social interactions and the associated perceptions of social partners. In this regard, BPD patients tend to attribute the cause of negative rather than positive events to their own person and to perceive others as less trustworthy than healthy controls (HCs). To date, no study has investigated whether the effect of experimentally influenced causal attributions of social interactions on the perception of a social partner differs between BPD patients and HCs.

METHODS

A new virtual reality paradigm was developed to investigate the perception of benevolence following the induction of social rejection and acceptance, while experimentally manipulating whether an external cause for this behavior was provided. The data of 62 participants (32 HCs, 30 BPD patients) were analyzed using linear mixed-effects models. Associations of benevolence ratings with attributional style, rejection sensitivity, self-esteem, childhood trauma, and loneliness were investigated via correlational and multiple linear regression analyses.

RESULTS

Across both groups, a social partner was rated as less benevolent following rejection than following acceptance. An external explanation mitigated this negative effect of rejection. Overall, benevolence ratings were lower in BPD patients than in HCs. This group difference was stronger following acceptance than following rejection. Independent of acceptance and rejection, an external explanation was associated with a higher level of benevolence only in the HC group. No associations of the effects of the experimental conditions with attributional style, childhood trauma, rejection sensitivity, self-esteem, or loneliness were found.

CONCLUSION

Our findings indicate that acceptance and provided external explanations for rejection have a less positive impact on the perception of a social partner's attitude toward oneself in BPD patients than in HCs. More research is needed to identify predictors of benevolence perception and which steps of social information processing are altered. The therapeutic implications include the importance of strengthening the perception and enjoyment of being accepted as well as improving the mentalizing ability of BPD patients.

Childhood maltreatment is linked to larger preferred interpersonal distances towards friends and strangers across the globe

Childhood maltreatment (CM) is thought to be associated with altered responses to social stimuli and interpersonal signals. However, limited evidence exists that CM is linked to larger comfortable interpersonal distance (CID) - the physical distance humans prefer towards others during social interactions. However, no previous study has investigated this association in a comprehensive sample, yielding sufficient statistical power. Moreover, preliminary findings are limited to the European region. Finally, it is unclear how CM affects CID towards different interaction partners, and whether CID is linked to social functioning and attachment. To address these outstanding issues, adults (N = 2986) from diverse cultures and socio-economic strata completed a reaction time task measuring CID towards an approaching stranger and friend. Higher CM was linked to a larger CID towards both friends and strangers. Moreover, insecure attachment and less social support were associated with larger CID. These findings demonstrate for the first time that CM affects CID across countries and cultures, highlighting the robustness of this association.

Pathways Linking Parental Care and Control to Loneliness in Breast Cancer Patients with A History of Childhood Maltreatment: Exploring the Mediating Roles of Ambivalence Over Emotional Expression and Self-Discrepancy

Childhood maltreatment is a risk factor for loneliness and is linked to breast cancer. Parental bonding experienced during one's childhood also plays a significant role in increasing or decreasing the risk of loneliness later in life. Previous research has highlighted the significance of ambivalence over emotional expression (AEE) and self-discrepancy in the psychological adaptation of breast cancer patients, particularly concerning the impact of parental care and control experienced by patients in their relationship with their parents during childhood. Nevertheless, previous studies have not examined the mediating effects of AEE and self-discrepancy on parental care and control, as well as loneliness, in breast cancer patients. This study aimed to investigate whether AEE and self-discrepancy mediate the association of childhood parental care and control with loneliness in breast cancer patients with a history of childhood maltreatment. One hundred and thirty-three breast cancer patients who were receiving chemotherapy within the first 3 months post-diagnosis were recruited from one private and three public hospitals in Tabriz, Iran, to complete questionnaires. Parental bonding, loneliness, AEE, and self-discrepancy were assessed using the Parental Bonding Instrument (PBI), University of California Los Angeles (UCLA) Loneliness Scale, Ambivalence over the Expression of Emotion Questionnaire (AEQ), and Self-Discrepancies Scale (S-DS). Mediation models were tested using structural equation modeling. Effects of parental care (β = -.17, p < .05) and control (β = .21, p < .001) on loneliness were significant. Furthermore, both AEE (β = .19, p < .05) and self-discrepancy (β = .23, p < .01) significantly predicted loneliness. The pathway between parental care and AEE was significant (β = -.21, p < .001), as was the direct effect of parental control on self-discrepancy (β = .19, p < .05). Bootstrapping results showed that AEE significantly mediated the relationship between parental care and loneliness (95% confidence interval [CI] [-0.09, -0.01]). In addition, there was a significant indirect effect from parental control to loneliness via self-discrepancy (95% CI [0.11, 0.01]). These findings suggest that AEE and self-discrepancy could potentially be utilized in preventing or addressing loneliness in breast cancer patients who have a history of childhood maltreatment. Future research could, for example, assess whether integrating psychosocial interventions focusing on these variables as part of medical care can improve the mental health status of this subgroup of breast cancer patients who have experienced childhood maltreatment.

Predictors and moderators of outcome of ICBT for loneliness with guidance or automated messages - A secondary analysis of a randomized controlled trial

Internet-based cognitive behavioral therapy (ICBT) is promising in alleviating loneliness in adults. Identifying individuals who benefit from ICBT for loneliness is pivotal to offering this intervention in a more targeted way and improving the intervention for those who do not benefit. This secondary analysis of a randomized controlled trial (RCT) aimed to identify predictors and moderators of outcome of an ICBT with guidance or automated messages for loneliness. In the RCT, 243 participants suffering from loneliness were randomly assigned to an ICBT with guidance (n = 98), automated messages (n = 97), or a waitlist-control condition (n = 48). In total, 180 participants completed the post-assessment (i.e., 10 weeks post-randomization). Outcomes were treatment outcome assessed with the UCLA-9 Loneliness Scale at post-assessment and treatment response, i.e., reliable improvement on the UCLA-9 from pre- to post. The relationship between a wide range of patient characteristics (grouped into socio-demographic, clinical, loneliness-specific, and treatment-related variables) and outcome was analyzed using multiple linear and logistic regressions. Feeling less burdened by loneliness resulted in higher odds of reliable improvement in guided ICBT compared to the waitlist-control condition. No treatment outcome or response moderators were identified for ICBT with automated messages compared to the waitlist-control group. Across active intervention groups, loneliness at baseline, age and fit between the tasks and goals of the intervention and participants' need predicted treatment outcome. Predictors of treatment response for ICBT with guidance and automated messages were not identified, and no variables differentially predicted the effects of ICBT with guidance or automated messages on the outcomes. In conclusion, individuals less burdened by their feelings of loneliness benefited more from guided ICBT. Lower baseline loneliness scores, younger age, and a better match between tasks and goals of the intervention and participants' needs also predicted a more favorable treatment outcome for both ICBT with guidance and automated messages.

Transdiagnostic analysis of adverse childhood experiences and their association with psychopathology-A TRANS-D conform study

Transdiagnostic approaches challenge traditional psychiatric classification systems. Adverse childhood experiences (ACE) represent a transdiagnostic risk factor for psychopathology with dose dependency. As different qualities of ACE typically co-occur, we identified ACE patterns to assess their power for predicting psychopathology compared to traditional diagnoses. Following TRANS-D guidelines, we categorized participants (N=360) with persistent depressive disorder (PDD), borderline personality disorder (BPD), or healthy control status (HC) into subcategories defined by ACE pattern, using the Childhood Trauma Questionnaire (CTQ). Improvement of the transdiagnostic vs. diagnostic approach in predicting psychopathology was evaluated in a cross-validated predictive modeling framework focusing on the clinical sample of PDD and BPD patients. Results were externally validated in another transdiagnostic sample (N=138). Seven pattern-based subcategories with distinct ACE profiles were identified in the primary sample and replicated in the validation sample. Patterns cut across diagnostic groups. Predictive modeling showed that diagnoses could not predict depressive symptoms and loneliness. Transdiagnostic constructs systematically predicted all measures. This study showcases ACE as a promising construct for transdiagnostic research. Our data-driven framework identified robust ACE subcategories mapping onto general and interpersonal psychopathology. Patterns of CTQ-based information may provide an approach to integrating information on co-occurring ACE to inform diagnostics and treatment.

Correlation between childhood trauma experience and depressive symptoms among young adults: The potential mediating role of loneliness

BACKGROUND

It is widely recognized that childhood trauma poses a significant risk of developing depressive symptoms. However, the underlying mediation mechanism between childhood trauma and depressive symptoms requires further exploration.

OBJECTIVE

This study focuses on exploring whether loneliness may act as a potential mediator between childhood trauma and depressive symptoms.

PARTICIPANTS AND SETTING

We analyzed a large sample of college students (N = 7293). Participants completed online questionnaires in the WeChat group.

METHODS

Childhood trauma, depressive symptoms, and loneliness were evaluated using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Patient Health Questionnaire-9 (PHQ-9), and the University of California Los Angeles Loneliness Scale (UCLA-LS) respectively. The linear regression method was applied to explore the mediating role.

RESULTS

Gender, relationship with family, and left-behind experience are all substantial depressive symptoms risk factors. Childhood trauma was shown to be highly related to depressive symptoms, and this relationship was potentially mediated by loneliness.

CONCLUSIONS

Our research indicates that treating loneliness in those who have undergone childhood trauma may help prevent or treat depressive symptoms. Therefore, loneliness should be taken into consideration while treating and preventing depressive symptoms.

Childhood trauma and real-world social experiences in psychosis

BACKGROUND

Childhood trauma is associated with a variety of negative outcomes in psychosis, but it is unclear clear if childhood trauma affects day-to-day social experiences. We aimed to examine the association between childhood trauma and functional and structural characteristics of real-world social relationships in psychosis.

METHODS

Participants with psychotic disorders or affective disorders with psychosis completed ecological momentary assessments (EMAs) over ten days (N = 209). Childhood trauma was assessed retrospectively using the Childhood Trauma Questionnaire. Associations between childhood trauma and EMA-assessed social behavior and perceptions were examined using linear mixed models. Analyses were adjusted for sociodemographic characteristics and psychotic and depressive symptom severity.

RESULTS

Higher levels of childhood trauma were associated with more perceived threat (B = -0.19, 95 % CI [-0.33, -0.04]) and negative self-perception (B = -0.18, 95 % CI [-0.34, -0.01]) during recent social interactions, as well as reduced social motivation (B = -0.29, 95 % CI [-0.47, -0.10]), higher desire for social avoidance (B = 0.34, 95 % CI [0.14, 0.55]), and lower sense of belongingness (B = -0.24, 95 % CI [-0.42, -0.06]). These negative social perceptions were mainly linked with emotional abuse and emotional neglect. In addition, paranoia was more strongly associated with negative social perceptions in individuals with high versus low levels of trauma. Childhood trauma was not associated with frequency (i.e., time spent alone) or type of social interactions.

CONCLUSION

Childhood trauma - particularly emotional abuse and neglect - is associated with negative social perceptions but not frequency of real-world social interactions. Our findings suggest that childhood trauma may affect day-to-day social experiences beyond its association with psychosis.
