Most people have experienced loneliness and have been able to overcome it to reconnect with other people. In the current review, we provide a life-span perspective on one component of the evolutionary theory of loneliness—a component we refer to as the reaffiliation motive (RAM). The RAM represents the motivation to reconnect with others that is triggered by perceived social isolation. Loneliness is often a transient experience because the RAM leads to reconnection, but sometimes this motivation can fail, leading to prolonged loneliness. We review evidence of how aspects of the RAM change across development and how these aspects can fail for different reasons across the life span. We conclude with a discussion of age-appropriate interventions that may help to alleviate prolonged loneliness.

The present study employed latent growth mixture modeling to discern distinct trajectories of loneliness using data collected at 2‐year intervals from age 7–17 years (N = 586) and examine whether measures taken at age 5 years were good predictors of group membership. Four loneliness trajectory classes were identified: (1) low stable (37% of the sample), (2) moderate decliners (23%), (3) moderate increasers (18%), and (4) relatively high stable (22%). Predictors at age 5 years for the high stable trajectory were low trust beliefs, low trusting, low peer acceptance, parent reported negative reactivity, an internalizing attribution style, low self‐worth, and passivity during observed play. The model also included outcome variables. We found that both the high stable and moderate increasing trajectories were associated with depressive symptoms, a higher frequency of visits to the doctor, and lower perceived general health at age 17. We discuss implications of findings for future empirical work.

Prior research has suggested that loneliness is associated with an implicit hypervigilance to social threats-an assumption in line with the evolutionary model of loneliness that indicates feeling socially isolated (or on the social perimeter) leads to increased attention and surveillance of the social world and an unwitting focus on self-preservation. Little is known, however, about the temporal dynamics for social threat (vs. nonsocial threat) in the lonely brains. We used high-density electrical neuroimaging and a behavioral task including social and nonsocial threat (and neutral) pictures to investigate the brain dynamics of implicit processing for social threat vs. nonsocial threat stimuli in lonely participants (N = 10), compared to nonlonely individuals (N = 9). The present study provides evidence that social threat images are differentiated from nonsocial threat stimuli more quickly in the lonely (~116 ms after stimulus onset) than nonlonely (~252 ms after stimulus onset) brains. That speed of threat processing in lonely individuals is in accord with the evolutionary model of loneliness. Brain source estimates expanded these results by suggesting that lonely (but not nonlonely) individuals showed early recruitment of brain areas involved in attention and self-representation.

Emotional intelligence (EI) may promote wellbeing through facilitation of adaptive attentional processing patterns. In the current study, a total of 54 adults (43 females, mean age = 25 years, SD = 10 years) completed a Trait Emotional Intelligence (TEI) scale and took part in three eye-tracking tasks, where they viewed (1) faces with different emotions (happy, angry, fearful, neutral), (2) 16-face crowds with varying ratios of happy to angry faces, and(3) 4 visual scenes (physical threat, social threat, positive social, neutral). Findings showed that higher TEI was associated with more attention to positive emotional stimuli (happy faces, positive social scenes), relative to negative and neutral stimuli. An attentional preference for positive rather than negative emotional stimuli may be one way that TEI affords protection from stressors to promote mental health.Trait emotional intelligence and attentional bias for positive emotion: An eye tracking study

Purpose Personalised information and support can be provided to cancer survivors using a structured approach. Needs assessment tools such as the Holistic Needs Assessment (HNA) in the UK and the Comprehensive Problem and Symptom Screening (COMPASS) questionnaire in Canada are recommended for use in practice; however, they are not widely embedded into practice. The study aimed to determine the extent to which nurses working in cancer care in the UK and Manitoba value NA and identify any barriers and facilitators they experience. Method Oncology nurses involved in the care of cancer patients in the UK (n = 110) and Manitoba (n = 221) were emailed a link to an online survey by lead cancer nurses in the participating institutions. A snowball technique was used to increase participation across the UK resulting in 306 oncology nurses completing the survey in the UK and 116 in Canada. Results Participants expressed concerns that these assessments were becoming bureaucratic “tick-box exercises” which did not meet patients’ needs. Barriers to completion were time, staff shortages, lack of confidence, privacy, and resources. Facilitators were privacy for confidential discussions, training, confidence in knowledge and skills, and referral to resources. Conclusion Many busy oncology nurses completed this survey demonstrating the importance they attach to HNAs and COMPASS. The challenges faced with implementing these assessments into everyday practice require training, time, support services, and an appropriate environment. It is vital that the HNA and COMPASS are conducted at optimum times for patients to fully utilise time and resources.

Background and Purpose— Identifying the etiology of acute ischemic stroke is essential for effective secondary prevention. However, in at least one third of ischemic strokes, existing investigative protocols fail to determine the underlying cause. Establishing etiology is complicated by variation in clinical practice, often reflecting preferences of treating clinicians and variable availability of investigative techniques. In this review, we systematically assess the extent to which there exists consensus, disagreement, and gaps in clinical practice recommendations on etiologic workup in acute ischemic stroke. Methods— We identified clinical practice guidelines/consensus statements through searches of 4 electronic databases and hand-searching of websites/reference lists. Two reviewers independently assessed reports for eligibility. We extracted data on report characteristics and recommendations relating to etiologic workup in acute ischemic stroke and in cases of cryptogenic stroke. Quality was assessed using the AGREE II tool (Appraisal of Guidelines for Research & Evaluation). Recommendations were synthesized according to a published algorithm for diagnostic evaluation in cryptogenic stroke. Results— We retrieved 16 clinical practice guidelines and 7 consensus statements addressing acute stroke management (n=12), atrial fibrillation (n=5), imaging (n=5), and secondary prevention (n=1). Five reports were of overall high quality. For all patients, guidelines recommended routine brain imaging, noninvasive vascular imaging, a 12-lead ECG, and routine blood tests/laboratory investigations. Additionally, ECG monitoring (>24 hours) was recommended for patients with suspected embolic stroke and echocardiography for patients with suspected cardiac source. Three reports recommended investigations for rarer causes of stroke. None of the reports provided guidance on the extent of investigation needed before classifying a stroke as cryptogenic. Conclusions— While consensus exists surrounding standard etiologic workup, there is little agreement on more advanced investigations for rarer causes of acute ischemic stroke. This gap in guidance, and in the underpinning evidence, demonstrates missed opportunities to better understand and protect against ongoing stroke risk.

Prior research has shown that loneliness is associated with hypervigilance to social threats, with eye-tracking research showing lonely people display a specific attentional bias when viewing social rejection and social exclusion video footage (Bangee, Harris, Bridges, Rotenberg & Qualter, 2014; Qualter, Rotenberg, Barrett et al., 2013). The current study uses eye-tracker methodology to examine whether that attentional bias extends to negative emotional faces and negative social non-rejecting stimuli, or whether it could be explained only as a specific bias to social rejection/exclusion. It is important to establish whether loneliness relates to a specific or general attention bias because it may explain the maintenance of loneliness. Participants (N = 43, F = 35, Mage = 20 years and 2 months, SD = 3 months) took part in three tasks, where they viewed different social information: Task 1 - slides displaying four faces each with different emotions (anger, afraid, happy and neutral), Task 2 - slides displaying sixteen faces with varying ratios expressing happiness and anger, and Task 3 - slides displaying four visual scenes (socially rejecting, physically threatening, socially positive, neutral). For all three tasks, eye movements were recorded in real time with an eye-tracker. Results showed no association between loneliness and viewing patterns of facial expressions, but an association between loneliness and hypervigilant viewing of social rejecting stimuli. The findings indicate that lonely adults do not have a generalised hypervigilance to social threat, but have, instead, a specific attentional bias to rejection information in social contexts. Implications of the findings for interventions are discussed.
