· John Cacioppo - Loneliness: Human Nature and the Need for Social Connection
Notes
Results
Approximately 20% of the children reported loneliness at each time point, 5% always felt lonely, and 25% wished they had more friends. Conduct and emotional problems, and hyperactivity were independently associated with loneliness in the multiple-regression analysis. The strength of these associations remained at similar levels over the 24-year study period. Living in a nonnuclear family, parents with a lower level of vocational education, and negative life events among the girls in the study were all associated with loneliness.
Conclusions
Loneliness was a common phenomenon in childhood, and no notable changes were found during the 24-year study period. Psychiatric symptoms were strongly associated with loneliness. It is important to pay attention to children's loneliness and make it an integral part of school health care. Further epidemiological research is needed.
Is there an operational definition of loneliness?
Loneliness is an emotionally unpleasant state during which a person’s desired interpersonal relationships do not match their actual relationships.18 Thus, loneliness is characterized by unmet expectations regarding social and intimate needs. Loneliness can be subtyped into various categories: a) emotional loneliness is defined by the lack of intimate relationships; and b) social isolation entails the lack of a social network that is stable.11, 19, 39 Loneliness may be further subdivided based on its causes.28, 36 Internal loneliness is associated with perceived loneliness and may arise due to personality factors, mental distress, personality, low self-esteem or self-worth, ineffective coping strategies, and negative emotions such as worthlessness and guilt. Reasons for situational loneliness include environmental factors (e.g., interpersonal issues and unpleasant experiences, the dispensary between desired and current number of social contacts, population migration, and disasters or accidents). Finally, developmental loneliness results from a misbalance between the need for intimacy or relatedness and the need for individualism. Specific factors leading to developmental loneliness include developmental deficits, social marginalization, significant separation(s), living environment, personal inadequacies, and physical and/or psychological disabilities.28, 36 Overall, there is agreement that loneliness arises due to perceived deficiencies in interpersonal or social relationships.39 Further, loneliness and social isolation are not a singular construct, as it is the perception of loneliness that matters, not physical or social isolation.39Finally, it is clear in the literature that loneliness is a subjective, nevertheless, distressing experience.39
Why is loneliness such a concern in modern N.A? Is there need for concern?
Due to the rise of technology, digital communication is increasingly relied upon to initiate and maintain relationships, which is concerning as social Internet use and loneliness have a bidirectional relationship.29 When used properly, social media use may be advantageous for relationships; however, individuals who use media-based communication to replace in-person may be at risk for greater loneliness. This increased use of technology-based communication can also be observed in the workplace, as many employers are offering employees the opportunity to work remotely; however, remote work may result in greater perceived isolation and loneliness.1 This sense of loneliness may also be experienced by non-remote employees with high stress and fast-paced jobs.1 This overreliance on technology-based recourses over social resources is concerning given the negative psychological and physical well-being outcomes associated with increased loneliness discussed below.
What in our culture has contributed to the loneliness problem?
North America demonstrates a preference of individualistic values over collective values, emphasizing competitiveness, individual over team achievement, impersonal relationships, and attaining profit and power.34In comparison to collectivist cultures, individualistic cultures are distinguished by increased rates of divorce and single-person homes, as well as decreased family sizes and social networks.34 Furthermore, loneliness may be intensified for people unable to meet various cultural standards or expectations relating to interpersonal relationships (e.g., ability to find a spouse or significant other).34 Additionally, technological advances have shaped how people now communicate with one another (i.e., preference for online over in-person interaction).34 This is problematic, as increased Internet use is related to a decline and family communication, a decreased social network, and an increase in loneliness and depression.20
What impacts does loneliness have on people’s overall wellbeing?
A review by Heinrich and Gullone revealed that loneliness predicted psychosocial difficulties (e.g., decreased social competence and self-esteem), decreased mental health (e.g., depression, anxiety, suicidality), and physical health problems (e.g., diminished cardiovascular and immune system functioning, as well as sleep impairment).18 Specifically, loneliness may lead to cancer, obesity, poor hearing, aging, reduced health overall, and is associated with adverse life experiences (e.g., child abuse).28
Does loneliness increase the likelihood of mental health problems?
Overall, loneliness is associated with diminished well-being.36 Specifically, loneliness may lead to alcohol abuse, personality disorders, depression, anxiety, suicidality, bulimia, and Alzheimer disease.18, 28, 36, 39 Additionally, while bereavement is not a psychiatric condition, many individuals suffering from grief may also experience greater loneliness.39
Loneliness and Solitude
Loneliness is a negative experience characterized by dissatisfaction with both aloneness and perceived quality of social interactions; conversely, solitude is a positive experience characterized by an intrinsic desire for voluntary aloneness allowing for greater a greater sense of connection to oneself and greater self-reflection.16, 17 While loneliness has been identified as a mental health concern,31solitude may be sought-out for the purpose of restoration or rejuvenation.22 Notably, loneliness has been linked to an external locus of control,19 in other words, lonely individuals are more likely to have a diminished sense of agency, believing that life-events arise due to factors outside of their control; specifically, due to random chance, other people’s actions, or environmental factors. In contrast, researchers have proposed that solitude leads to increased sense of agency and empowerment; therefore, it is possible that individuals who seek-out solitude are more likely to have an internal locus of control, believing that life-events are influenced by personal actions and abilities.
Myth: Loneliness mostly just impacts old people
Contrary to widespread belief, loneliness is less prevalent during old age and is more common during early developmental periods; specifically, during adolescent and young adulthood.18, 39 Notably, a national report revealed that individuals between the ages of 18 and 22 are at the higest risk of experiencing loneliness.30 Though, even young children may experience loneliness. For example, one study assessing the prevalence of loneliness during early childhood found that 12% of kindergarteners and children in first grade reported feelings of loneliness at school.7 However, it is important to note that loneliness impacts a large percentage of the population;39 for example, one report revealed that 50% of Americans experience either transient or chronic loneliness.3- Risk factors associated with loneliness include being a female and/or being unmarried; notably, older unmarried men may experience greater loneliness than unmarried women who are older.39
Myth: Loneliness will make people crazy.
Research has found that patients suffering from psychosis are at six times the risk of facing loneliness in comparison to individuals without a psychotic disorder.27 Chau and colleagues conducted a meta-analysis that revealed that loneliness has a medium link to positive psychotic symptoms;8 specifically, results revealed a robust relationship between paranoia and loneliness. In a second meta-analysis, loneliness was shown to have a medium correlation with negative psychotic symptoms.8 However, it should be noted that evidence suggests that the relationship between paranoia and loneliness is mediated by negative interpersonal schemas.21
Myth: Loneliness and social anxiety are the same thing.
Research has tested whether loneliness and social anxiety are a singular trait: Results revealed that loneliness and social anxiety are distinct constructs that are both related to interpersonal difficulties.15Like social anxiety, loneliness is maintained by self-protective, avoidance behaviour.15While social anxiety and loneliness are not the same, individuals with social anxiety disorder are at greater risk of experiencing loneliness.6, 25
Is technology a solution to loneliness? Do online friendships replace in-person friendships?
While technology may enable social interaction, it may also serve as a barrier depending on its use.24, 29 Specifically, technology reduces loneliness when used to initiate communication, friendship, and offline relationships.14, 24 In one study, social avoidance and loneliness predicted increased time spent on Facebook and was inversely associated with the number of intimate Facebook friends.23 These findings indicate that people who experience greater levels of loneliness and demonstrate increased avoidance of social situations may use Facebook as an outlet, possibly to compensate for a lack of in-person relationship or for reduced interpersonal skills.23, 37 These findings may be explained by the social competence hypothesis, which proposes that socially anxious or introverted individuals demonstrate a greater reliance on the Internet, due to a struggle to develop in-person relationships.37 While technology may be a solution to loneliness when used wisely, online interpersonal relationships are not sufficient in replacing in-person friendships.
How can we reduce our loneliness?
Broadly speaking there are four primary interventions for loneliness including, a) the development of social skills, b) targeting maladaptive cognitions, c) providing social support, and d) providing opportunities for group interaction.26, 28 It is important that interventions are individualized, taking people’s available resources and unique circumstances into consideration.24 In addition to planned interventions, loneliness may be mitigated through use of strategies, including distraction (e.g., keeping busy), being emotionally vulnerable, participation in activities, reinforcing quality relationships, helping others, pharmacological treatment for ailments, and keeping in contact with valued people.36
What reasons are there to have hope that your loneliness can change? (incremental cultivation)
Changing our mindsets may allow us to change our perceived loneliness. Individuals may either hold and fixed or a growth mindset of social interaction.35 People with a fixed mindset of social interaction believe that their relationships are unchangeable, while individuals with a growth mindset believe their social interactions and interpersonal competence can change and improve through effort.35 Research has shown that fixed mindset of friendship and social competence predicts greater levels of loneliness.35 Luckily, we can adopt more adaptive mindsets of interpersonal relationships by focusing more so on learning processes and by concentrating on ways to increase social competence.35 Common interventions to induce a growth mindset include exposing oneself to arguments in favour of such a mindset.35

a. This article depicts the analyses necessary to construct models for subcategories of loneliness. 1255 older individuals were recruited to participate. Results indicated 19.36% of shared variance for social and emotional loneliness. Variables that emerged as a predictor of social loneliness that was non-overlapping with emotional loneliness included decreased levels of perceived community integration, being male, decreased family and friend contact, reduced activity, and being a recipient of community care. Variables that emerged as a predictor of emotional loneliness that was non-overlapping with social loneliness included high activity restriction and being a non-recipient of informal care. For significant predictors of social loneliness: R = 0.50, R2 = 0.25, F(18, 979) = 18.17, p < 0.001). For significant predictors of emotional loneliness: R = 0.55, R2 = 0.30, F (18, 973)=23.00, p < 0.001).
