Loneliness in everyday life: cardiovascular activity,psychosocial context,and health behaviors

Prior lab research revealed higher basal total peripheral resistance (TPR) and lower cardiac output (CO) in lonely than in nonlonely young adults. In this study, experience sampling was used to obtain ambulatory blood pressure; impedance cardiography: and reports of activities, appraisals, interactions, and health behaviors. Results confirmed that loneliness predicted higher TPR and lower CO during a normal day. Loneliness did not predict differences in time spent alone, daily activities, or health behaviors but did predict higher stress appraisals and poorer social interactions. Independent of loneliness, interaction quality contributed to TPR. Loneliness differences were not mediated by depressed affect or neuroticism. Social support mediated loneliness differences in stress and threat. Concomitants of loneliness were comparable for men and women.     

The prevalence of loneliness among adults: a case study of the United Kingdom

Within contemporary Western (post) modern societies, loneliness is seen as a problem that is particularly associated with old age. Much less attention has been given to examining variations in loneliness across age groups. We examine patterns of loneliness across adults aged 15 years and older in the United Kingdom using data from the European Social Survey. We first consider the prevalence of loneliness among the adult population; then the relationship between loneliness and a range of key risk factors, and finally the relationship with age for each of our risk factors. Loneliness demonstrates a nonlinear U-shaped distribution, with those aged under 25 years and those aged over 65 years demonstrating the highest levels of loneliness. Depression is associated with loneliness for all age groups. Poor physical health is associated with loneliness in young adult and midlife but not later life. For those in mid and later life, the quality of social engagement is protective against loneliness, while for young adults it is the quantity of social engagement. This indicates that different factors may endow vulnerability (or protect) against loneliness at different stages of life and suggests that preventative strategies or interventions that reflect these variations need to be developed.     

Loneliness accentuates age differences in cardiovascular responses to social evaluative threat

The effects of aging and loneliness on cardiovascular stress responses were examined in 91 young (18-30 years) and 91 older (65-80 years) normotensive adults. Participants completed the revised UCLA Loneliness Scale and a modified version of the Trier Social Stress Test. Piece-wise linear growth-curve analysis was used to model group differences in resting, reactivity, and recovery levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Replicating and extending prior research, analyses revealed age-related increases in resting SBP and DBP. Adjusting for demographics and health covariates, interactions were found for SBP in which age differences in stress reactivity and recovery were greater among lonely than nonlonely participants. Findings provide further evidence that loneliness interacts with age to augment cardiovascular risk to social evaluative threat.     

A comparison of health behaviours in lonely and non-lonely populations

Loneliness can be defined as perceived social isolation and appears to be a relatively common experience in adults. It carries a significant health risk and has been associated with heart disease, depression and poor recovery after coronary heart surgery. The mechanisms that link loneliness and morbidity are unclear but one of the mechanisms may be through poor health beliefs and behaviours. The aims of this cross-sectional survey of 1289 adults were to investigate differences in health behaviours (smoking, overweight, BMI, sedentary, attitudes towards physical activity) in lonely and non-lonely groups. Lonely individuals were more likely to be smokers and more likely to be overweight - obese. The lonely group had higher body mass index scores controlling for age, annual income, gender, employment and marital status. Logistic regression revealed no differences in sedentary lifestyles. Lonely individuals were significantly less likely to believe it was desirable for them to lose weight by walking for recreation, leisure or transportation. The findings provide support for an association between health behaviours, loneliness and excess morbidity reported in previous studies.     

Cultural and emotional components of loneliness and depression

The relation between loneliness and depression and the distinction between emotional and social loneliness were examined by administering the University of California, Los Angeles (UCLA) Loneliness Scale, the Belcher Extended Loneliness Scale (BELS), the Beck Depression Inventory, and self-report questions about social and emotional loneliness to the following four groups: foreign (Chinese-descent) students in American universities, Chinese students in Taiwanese universities, American students in American universities, and depressed American clients. Depressed clients reported not only more depression but also more overall loneliness than did any of the other groups; they also were more likely to report emotional loneliness or both emotional and social loneliness than were the other three groups. Foreign students, in contrast, reported more social loneliness than did Taiwanese students. Results substantiate the view that loneliness is not a unitary concept and suggest that the UCLA Loneliness Scale and the BELS emphasize emotional rather than social loneliness and that emotional loneliness is a greater component of depression than is social loneliness.     

Adverse adolescence experiences,feeling lonely across life stages and loneliness in adulthood

Background/ObjectiveLoneliness is a mental health issue emerging over the life course. This study examines the latent structure of adult loneliness in a non-Western society and its association with adverse adolescence experiences (AAEs) as well as feeling lonely during middle school, high school, and college. Method: A cohort sample living in Northern Taiwan (N = 2,289) was analyzed from adolescence to adulthood. The de Jong Gierveld Loneliness Scale operationalized loneliness by a three-cluster model to present the latent structure of loneliness: emotional, serious emotional, and severe emotional/social loners. AAEs (e.g., abuse, neglect, and dysfunctional family) were measured by seven items. Multivariate multinomial logistic regression models were used to explore the longitudinal effects of AAEs and feeling lonely reported during middle school, high school, and college on adult loneliness. Results: AAEs and feeling lonely during adolescence were significantly associated with serious emotional loneliness and severe emotional/social loneliness during adulthood, even after adjusting for the individual’s characteristics. Attendance at a 4-year college was associated with decreased odds of serious emotional loneliness and severe emotional/social loneliness. Conclusions: Adults with AAEs and feelings of loneliness over life stages are more likely to report loneliness in the emotional and social domains.     

Lonely hearts: Psychological perspectives on loneliness

Loneliness is a complex set of feelings encompassing reactions to the absence of intimate and social needs. Although transient for some individuals, loneliness can be a chronic state for others. We review the developmental, social, personality, clinical, and counseling psychology literatures on loneliness with an emphasis on recent empirical findings. Chronic feelings of loneliness appear to have roots in childhood and early attachment processes. Chronically lonely individuals are more likely to be high in negative affectivity, act in a socially withdrawn fashion, lack trust in self and others, feel little control over success or failure, and generally be dissatisfied with their relationships compared to nonlonely individuals. Loneliness has also been associated with a variety of individual differences including depression, hostility, pessimism, social withdrawal, alienation, shyness, and low positive affect; loneliness is also a concomitant of more severe disorders, such as clinical depression, borderline personality, and schizophrenia. Although loneliness affects a large number of individuals and is associated with numerous negative outcomes, relatively few investigations have examined the efficacy of treatments aimed at alleviating or preventing loneliness. Several investigations raise the possibility of treating loneliness, but the absence of appropriate comparison groups casts doubt on the efficacy of many of these treatments. Correlational studies also suggest that one close friend or romantic partner may be sufficient to buffer those at risk for loneliness. Research on causal processes is sparse, however, and more research is needed to delineate which factors are antecedents and which are consequences of loneliness.     

Trait empathy as a predictor of individual differences in perceived loneliness

Loneliness has been shown to be inversely correlated with empathy in younger adults. The present study extends previous research by investigating the association between empathy and loneliness across the adult lifespan and examining the role of relevant demographic and personality factors. 110 community-dwelling adults (18 to 81 years old) completed the UCLA Loneliness Scale and the Empathy Quotient. Empathy scores were inversely associated with rated loneliness and predicted 8.7% of variance in loneliness scores after accounting for sex, age, relationship status, education, and neuroticism. The Social Skills factor of the Empathy Quotient was the strongest predictor of the association between perceived empathy and loneliness. Previous research is extended by the finding that rated loneliness was inversely associated with empathy scores across the adult lifespan. Underlying this relationship may be negative perceptions of personal social proclivity as a function of difficulty in understanding the mental states of others and high trait neuroticism.     

Sex differences in social support, loneliness, and depression among Korean college students

This study examined the sex differences in reports of social support (network size and satisfaction), loneliness, and depression among Korean college students and examined whether measures of social support and loneliness predicted depression scores. In the sample were 452 college students enrolled in four universities in Korea. The women reported a larger social support network size and being less satisfied with their support than the men. Women reported higher scores on the Revised UCLA Loneliness Scale and the Beck Depression Inventory than men. Social support satisfaction scores and network size on the Social Support Questionnaire-6 and scores on the Loneliness Scale predicted scores on Depression in both the groups. Loneliness was the largest predictor of Depression for either sex. The amount of variance in Depression accounted for by Loneliness was 35% for women and 24% for men.     

Loneliness: Its correlates and associations with health risk behaviours among university students in 25 countries

The aim of this cross-national study was to assess factors associated with loneliness and to determine the degree to which loneliness affects health status and risk behaviours among university students. Data were collected from 17 886 university students in 25 countries (females = 58.6%, from Africa = 33.5%). In multivariable logistic regression, loneliness was predicted by lower family wealth, living in a low or lower middle income country, and antecedent childhood. Moreover, psychosocial factors of perceived lack of control, low organised religious activity, high non-organised religious activity, high intrinsic religiosity, and low social support were associated with loneliness. Lonely students were also likely to self-report poor subjective health status, sleeping problems, short sleep duration, tobacco use, heavy internet use, aggressive behaviour, injury, and sexual risk behaviour. University students with loneliness may be assisted by preventive health interventions aimed at enhancing their subjective well-being.     

Loneliness, depression, social support, and quality of life in older chronically ill Appalachians

This study's purpose was to describe loneliness and to examine the relationships between loneliness, depression, social support, and QOL in chronically ill, older Appalachians. In-person interviews were conducted with a convenience sample of 60 older, chronically ill, community-dwelling, and rural adults. Those with dementia or active grief were excluded. The UCLA Loneliness Scale (Russell, Peplau, & Cutrona, 1985), Geriatric Depression Scale (Shiekh & Yesavage, 1986), Katz ADL scale (Katz, Down, & Cash, 1970), MOS Social Support Scale (Sherbourne & Stewart, 1991), and a visual analog scale for Quality of Life (Spitzer et al., 1981) scale were used. Diagnoses were obtained through chart reviews. SPSS was used for data analyses. The majority of the 65% female sample (M age = 75 years) were married and impoverished. Participants' number of chronic illnesses averaged more than 3. Over 88% of participants reported at least 1 area of functional impairment. Loneliness was prevalent with UCLA loneliness scores indicating moderate to high loneliness, ranging from 39 to 62 (possible scores were 20-80). Higher loneliness scores correlated with depression, lower Qol, and lower social support, particularly lower emotional support. This study provides evidence that loneliness is a significant problem for older chronically ill Appalachian adults and that it may be related to low emotional support. Further, it provides evidence that this population may be significantly lonely and may not self-identify as lonely. Screening for loneliness and designing interventions that target the emotional aspects of loneliness could be important in this population.     

Loneliness as a specific risk factor for depressive symptoms: cross-sectional and longitudinal analyses

The extent to which loneliness is a unique risk factor for depressive symptoms was determined in 2 population-based studies of middle-aged to older adults, and the possible causal influences between loneliness and depressive symptoms were examined longitudinally in the 2nd study. In Study 1, a nationally representative sample of persons aged 54 and older completed a telephone interview as part of a study of health and aging. Higher levels of loneliness were associated with more depressive symptoms, net of the effects of age, gender, ethnicity, education, income, marital status, social support, and perceived stress. In Study 2, detailed measures of loneliness, social support, perceived stress, hostility, and demographic characteristics were collected over a 3-year period from a population-based sample of adults ages 50-67 years from Cook County, Illinois. Loneliness was again associated with more depressive symptoms, net of demographic covariates, marital status, social support, hostility, and perceived stress. Latent variable growth models revealed reciprocal influences over time between loneliness and depressive symptomatology. These data suggest that loneliness and depressive symptomatology can act in a synergistic effect to diminish well-being in middle-aged and older adults.     

Toward a better understanding of loneliness in community-dwelling older adults

The purpose of this interpretive phenomenological study was to explore the meaning of loneliness in community-dwelling older adults and to understand their daily practices in coping with loneliness. The sample consisted of 8 women and 4 men. Interviews were conducted with the 12 participants utilizing several tools, including 3 separate interview guides and the UCLA Loneliness Scale, Version 3 (Russell, 1996). A critical finding was that many participants experienced loneliness as a result of disrupted meaningful engagement, due to age-related changes, as well as other losses, including death of spouse, retirement, and giving up the car. Two paradigm cases and themes representing the loneliness and coping experience emerged. Participant coping practices with loneliness included reaching out to others, helping those in need, and seeking companionship with pets. Many older adults are at risk for loneliness because of declining health and other age-related losses that prevent them from remaining engaged in meaningful relationships. Health care professionals can screen for loneliness to identify those at risk and can intervene to help older adults maintain connections. Recommendations for those caring for lonely older adults include active listening, vision and hearing screenings, transportation needs, pet therapy, volunteering, and engagement in social activities.

Early Cognitive Decline and Its Impact On Spouse’s Loneliness

Loneliness is common in dementia caregivers as cognitive impairment (CI) alters marital and social relationships. Unexplored is how an individual’s loneliness is affected at earlier, more ambiguous, periods of their spouse’s CI. Using the Health and Retirement Study, our study participants included 2,206 coupled individuals with normal cognitive function at the 2006/8 baseline. Loneliness outcomes at baseline, 4-year, and 8-year follow-up are assessed by the status of transition to cognitive impairment no dementia (TCIND) (2010/12 & 2014/16) using linear mixed models. Individual’s loneliness was stable when their spouse’s cognition remained normal, but increased with the spouse’s TCIND. The increase in loneliness did not vary by gender. Loneliness, a key risk factor for reduced life quality and increased depression, increases even at early stages of a partner’s CIND. This work suggests the potential impact of early intervention and social support for partners of individuals with CIND.     

Age and gender differences in and personality correlates of loneliness in different relationships

This study examined age and gender differences in and personality correlates of loneliness in different relationships. Loneliness was measured in three groups of subjects (college men, college women, and elderly women) with the Differential Loneliness Scale which assesses dissatisfaction with four types of relationships (Family, Larger Groups, Friendships, and Romantic/Sexual). Age and gender differences were significant. Compared to elderly women, college women expressed more dissatisfaction with their Family and Large Group relationships. Compared to college women, elderly women expressed more dissatisfaction with their Friendships and Romantic/Sexual relationships. With regard to gender differences, college men expressed more dissatisfaction with Family, Large Group, and Friendship relationships than college women. For each subject group, dissatisfaction scores were correlated with health status, locus of control, social support, depression, and self-consciousness. Correlations varied with type of relationship as well as with age and gender. The group differences and the varying patterns of correlations support the use of a multidimensional approach to the study of loneliness. Results are discussed in terms of previous research and future investigations.

Determinants of loneliness of young adult drug users

Loneliness is a subjective experience that is influenced by such variables as personality, life experiences, and situation. In the present study, the author examined the connection between the use of ecstasy (MDMA) and the antecedents of loneliness. MDMA users were compared with non-MDMA drug users and with a group of young adults in the general population who did not use drugs. A total of 818 participants from all 3 groups volunteered to answer a 30-item yes-no questionnaire reflecting on their experiences of loneliness and what caused them. Results showed that the predominant causes of loneliness were personal inadequacies, developmental deficits, unfulfilling intimate relationships, relocation or significant separations, and social marginality. There were significant differences between the scores of the MDMA users and scores of the other groups. Gender differences between and within groups were also examined.     

Sex Differences in Loneliness: The Role of Masculinity and Femininity

The present study assessed the magnitude of sexdifferences in loneliness after accounting for theinfluence of two covariates: masculinity and femininity.The 256 participants (principally White, somewhat affluent, and middle-class university students)completed both the UCLA Loneliness Scale and the Bem SexRole Inventory. Whereas sex differences were originallynonsignificant (males tended to be lonelier than females), this difference was significantafter accounting for masculinity (not femininity)embedded in participants' loneliness scores. Similarresults emerged when the covariates were partialled out of both loneliness (criterion) and sex(predictor). These findings support the hypothesis thatmales appear reluctant to admit feelings of loneliness.Male reluctance to personally admit social deficits such as loneliness is suggested for futureresearch.
