A hypothesized need to form and maintain strong, stable interpersonal relationships is evaluated in light of the empirical literature. The need is for frequent, nonaversive interactions within an ongoing relational bond. Consistent with the belongingness hypothesis, people form social attachments readily under most conditions and resist the dissolution of existing bonds. Belongingness appears to have multiple and strong effects on emotional patterns and on cognitive processes. Lack of attachments is linked to a variety of ill effects on health, adjustment, and well-being. Other evidence, such as that concerning satiation, substitution, and behavioral consequences, is likewise consistent with the hypothesized motivation. Several seeming counterexamples turned out not to disconfirm the hypothesis. Existing evidence supports the hypothesis that the need to belong is a powerful, fundamental, and extremely pervasive motivation.

The need to belong: Desire for interpersonal attachments as a fundamental human motivation.

Most current models in health psychology assume that stress adversely affects physical health. We re-examined this assumption by reviewing extensive data from the literature and from six samples of our own, in which we collected measures of personality, health and fitness, stress, and current emotional functioning. Results indicate that self-report health measures reflect a pervasive mood disposition of negative affectivity (NA); self-report stress scales also contain a substantial NA component. However, although NA is correlated with health compliant scales, it is not strongly or consistently related to actual, long-term health status, and thus will act as a general nuisance factor in health research. Because self-report measures of stress and health both contain a significant NA component, correlations between such measures likely overestimate the true association between stress and health. Results demonstrate the importance of including different types of health measures in health psychology research.

Health complaints, stress, and distress: exploring the central role of negative affectivity.

As a social species, humans rely on a safe, secure social surround to survive and thrive. Perceptions of social isolation, or loneliness, increase vigilance for threat and heighten feelings of vulnerability while also raising the desire to reconnect. Implicit hypervigilance for social threat alters psychological processes that influence physiological functioning, diminish sleep quality, and increase morbidity and mortality. The purpose of this paper is to review the features and consequences of loneliness within a comprehensive theoretical framework that informs interventions to reduce loneliness. We review physical and mental health consequences of loneliness, mechanisms for its effects, and effectiveness of extant interventions. Features of a loneliness regulatory loop are employed to explain cognitive, behavioral, and physiological consequences of loneliness and to discuss interventions to reduce loneliness. Loneliness is not simply being alone. Interventions to reduce loneliness and its health consequences may need to take into account its attentional, confirmatory, and memorial biases as well as its social and behavioral effects.

Loneliness Matters: A Theoretical and Empirical Review of Consequences and Mechanisms

Recent years have witnessed a proliferation of research on close relationships and the emergence of a new relationship subdiscipline within the social sciences. To date, the new science of relationships has been dominated by data. This article is based on the conviction that progress now hinges on the development of theory to organize and interpret extant findings and to guide future investigations. Through a selective but extensive review of the major bodies of empirical literature, we attempt to show that attachment theory can incorporate a broad range of findings on adult relationships. In addition, attachment theory addresses an impressive array of research questions concerning the functions, emotional dynamics, evolutionary origins, and developmental pathways of human affectional bonds. We conclude that a comprehensive theory of close relationships is both desirable and, with the integration of existing theories and concepts, currently achievable.

Attachment as an Organizational Framework for Research on Close Relationships

The clinical significance of loneliness: a literature review.

This study examined the associations among loneliness, stressful life events, urinary cortisol levels, and immunocompetency. Blood and urine were obtained from 33 psychiatric inpatients on the day after admission, at which time the patients completed the UCLA Loneliness Scale, the Psychiatric Epidemiology Research Interview Life Events Scale (PERI), and the MMPI. Patients who scored above the median on loneliness had significantly higher urinary cortisol levels. The high loneliness group also had significantly lower levels of natural killer cell activity, as well as a poorer T-lymphocyte response to phytohemagglutinin. The high loneliness subjects descibed themselves as more distressed than the low loneliness group on the MMPI. There were no consistent significant effects on either the immunologic measures or the MMPI associated with the PERI.
