Supportive-leadership training to improve social connection: A cluster-randomized trial demonstrating efficacy in a high-risk occupational context.

The high, and still rising, rate of loneliness is a threat to public health (Office of the Surgeon General, 2023), with negative mental and physical health consequences (e.g., Holt-Lunstad, 2021). Given that loneliness is a risk factor for poor mental health, efforts to address loneliness are urgently needed. Workplaces can facilitate an employee's social connection through supervisor support training, which can help mitigate loneliness. Among occupational groups, the military is at higher risk for mental health disorders, suicide, and loneliness (Fikretoglu et al., 2022; Naifeh et al., 2019). This study evaluated the efficacy of an evidence-based supportive-leadership training intervention targeting active-duty U.S. Army platoon leaders and targeting both proactive support behaviors that help bolster employee social connection and responsive support behaviors, including destigmatizing mental health. Ninety-nine platoon leaders (69.7% of eligible leaders) completed the 90-min training that consisted of both in-person and computer-based components. Using a cluster-randomized controlled trial design, intervention effects were tested using an intent-to-treat approach and revealed a significant effect, whereby loneliness of service members whose leaders were randomized to the intervention group (N = 118) was significantly reduced compared to loneliness reports for service members in the control group (N = 158). Additionally, service members with higher baseline loneliness were more strongly and positively impacted by the supervisor training, reporting higher levels of supportive behaviors from their leaders at 3 months postbaseline. In sum, these results suggest how workplaces, especially those that are considered high-risk occupations, and their leaders play a critical role in a national strategy to address Americans' well-being.

Orienteering with One Endomorphism.

In supersingular isogeny-based cryptography, the path-finding problem reduces to the endomorphism ring problem. Can path-finding be reduced to knowing just one endomorphism? It is known that a small degree endomorphism enables polynomial-time path-finding and endomorphism ring computation (in: Love and Boneh, ANTS XIV-Proceedings of the Fourteenth Algorithmic Number Theory Symposium, volume 4 of Open Book Ser. Math. Sci. Publ., Berkeley, 2020). An endomorphism gives an explicit orientation of a supersingular elliptic curve. In this paper, we use the volcano structure of the oriented supersingular isogeny graph to take ascending/descending/horizontal steps on the graph and deduce path-finding algorithms to an initial curve. Each altitude of the volcano corresponds to a unique quadratic order, called the primitive order. We introduce a new hard problem of computing the primitive order given an arbitrary endomorphism on the curve, and we also provide a sub-exponential quantum algorithm for solving it. In concurrent work (in: Wesolowski, Advances in cryptology-EUROCRYPT 2022, volume 13277 of Lecture Notes in Computer Science. Springer, Cham, 2022), it was shown that the endomorphism ring problem in the presence of one endomorphism with known primitive order reduces to a vectorization problem, implying path-finding algorithms. Our path-finding algorithms are more general in the sense that we don't assume the knowledge of the primitive order associated with the endomorphism.

Drinking to Cope in the COVID-19 Era: An Investigation Among College Students.

OBJECTIVE: The COVID-19 pandemic has resulted in abrupt, drastic changes to daily life in many nations. Experiences within the United States have varied widely. In the State of Oregon in the early months of the pandemic protective protocols (e.g., social distancing) were comparatively high, resulting in concern for increases in loneliness and COVID-related stress. The present study of college students examined the indirect relationship of loneliness and other stressors to alcohol use, via drinking-to-cope motives. METHOD: A sample of traditional- and nontraditional-aged college students (N = 215; 68.1% female; mean age = 24.8 years) completed an online survey assessing COVID-19 experiences during shelter-in-place orders in Oregon over a 5-week period in April and May of 2020. RESULTS: Cross-sectional structural equational modeling revealed that loneliness and COVID-19 news consumption were associated with stronger coping motives, whereas rated seriousness of COVID-19 was related to weaker coping motives. Coping motives, in turn, were related to more frequent past-30-day consumption; significant indirect effects were revealed for all three predictors on drinking frequency and heavy drinking frequency, via drinking-to-cope motives. Drinking-to-cope motives were also related to greater past-30-day marijuana use. CONCLUSIONS: These findings provide insight into how COVID-related stressors and associated social relationship repercussions relate to alcohol and marijuana use and drinking-to-cope motivations while sheltering in place. These results have implications for how frequent substance use and coping-motivated use can be mitigated during a crisis.

The paradox of power: The relationship between self-esteem and gratitude.

In contrast to earlier research, the three studies reported here find that the most powerful individuals are also the most grateful, and that self-esteem plays a role in explaining this relationship. Study 1a (N = 109) reveals a strong, positive relationship between individuals' perceived power and gratitude. Study 1b (N = 194) replicates this and finds that self-esteem mediates this positive power-gratitude relationship. Study 2 (N = 212) manipulates power and shows its downstream effects on gratitude through self-esteem, again providing support for the positive relationship of power to gratitude through self-esteem. We argue that because gratitude is predicated on recognition that others value oneself, power amplifies rather than undercuts feelings of gratitude. We discuss possible boundary conditions.

Gratitude and Loneliness: Enhancing Health and Well-Being in Older Adults.

We experimentally investigated gratitude's impact on loneliness and health in older adults. Participants were assigned to a daily gratitude writing exercise (treatment group) or a control group. Self-reported loneliness and health (i.e., subjective well-being, subjective health, health symptoms) were measured daily over a 3-week period. In support of our hypotheses, within-person variability in gratitude predicted differences in loneliness and health. Furthermore, those in the treatment group showed stronger cumulative effects of gratitude on loneliness and health symptoms when aggregated across the 20-day study. Additionally, a series of conditional, multilevel indirect effect models found that loneliness acted as a mechanism for gratitude's differential impact on subjective well-being and health symptoms across conditions. Taken together, this study provides initial evidence that a simple gratitude exercise can strengthen associations among daily gratitude and loneliness and, consequently, improve health, for older adults.

Transient Loneliness and the Perceived Provision and Receipt of Capitalization Support Within Event-Disclosure Interactions.

Research affirms that loneliness is a distressing experience with social-perceptual and behavioral consequences. Yet, little is known about consequences of transient loneliness, particularly within social interactions. The current study builds on reaffiliation motive and evolutionary models of state loneliness to investigate the effects of experimentally manipulated loneliness on individual and interaction partner perceptions during an event-sharing interaction, within 97 female dyads. Actor-partner interdependence mediation analyses revealed indirect effects for induction group (high vs. low loneliness) on positive affect, enjoyment, responsiveness, and partner positive affect, via induced state loneliness. Furthermore, state loneliness influenced actor and partner provision of responsiveness, via perceived responsiveness. Results reveal interpersonal consequences of transient loneliness, offering preliminary insight into conditions through which state perceptions of isolation may interfere with engagement in positive social interactions. Furthermore, implications for previously theorized evolutionary models of state loneliness and the reaffiliation motive are discussed.

"A well spent day brings happy sleep": A dyadic study of capitalization support in military-connected couples.

Among couples, sleep is theorized to be a dyadic process, within which relationship quality exerts a large influence (Troxel, Robles, Hall, & Buysse, 2007). In turn, research has shown that capitalization, or positive-event disclosure, influences relationship quality. The benefits of capitalization, however, are contingent on the receipt of a supportive response, here referred to as capitalization support (Reis & Gable, 2003). Accordingly, the current study examined daily capitalization support, loneliness, and intimacy as predictors of sleep (i.e., quality, duration, difficulty falling asleep). Post-9/11 military veterans and their spouses (N = 159) completed a 32-day internet-based survey assessing daily relationship experiences and health. Results of an actor-partner interdependence mediation model on aggregated daily data revealed actor indirect effects of capitalization support on sleep outcomes via loneliness and intimacy, for veterans and spouses. Partner indirect effects were observed for veteran capitalization support on spouse difficulty falling asleep and sleep quality, via spouse loneliness and intimacy. Lagged actor-partner models revealed similar actor effects for daily capitalization support on loneliness (spouses) and intimacy (spouses and veterans), which in turn uniquely predicted daily sleep. Partner effects were observed for veteran capitalization support on spouse intimacy, and veteran loneliness on spouse sleep quality. Results highlight potential new avenues for interventions to promote better sleep by promoting positive relationship functioning between romantic partners. Such work is especially important for high-risk individuals, including military veterans and their spouses for whom prolonged postdeployment sleep difficulties pose particular concern.

Tumor imaging instruction and assessment at chiropractic colleges in North America: a pilot study with implications for National Board of Chiropractic Examiners content.

OBJECTIVE: This pilot study tested a survey instrument pertaining to the instruction and assessment of tumor imaging in chiropractic training programs. The secondary purpose was to gather data regarding credentials of lead instructors, textbook and resource use, and tumors taught and assessed. METHODS: An electronic survey was distributed to lead tumor imaging instructors at all chiropractic colleges in the United States and Canada. A focus group of tumor imaging instructors was conducted to clarify ambiguous data. RESULTS: Diplomate status with the American Chiropractic Board of Radiology was held by 87.5% of the instructor respondents. There were similarities in course content and assessment across institutions. A total of 26 tumors were considered clinically significant by more than 65% of instructors, 9 tumors were identified as not clinically significant by more than 65%, and 4 tumors were considered clinically significant by 35% to 65% of instructors. There was correlation between those instructors who evaluated on various tumors and those who feel it is important to evaluate such tumors (rS = 0.94, p < .001). The focus group addressed the 4 equivocal tumors and recommended 3 be added to the list of clinically insignificant tumors. CONCLUSION: The survey instrument is ready to be used to conduct a study of all clinical areas of the chiropractic curriculum. A total of 12 tumors were recommended for removal from National Board of Chiropractic Examiners tests. The authors recommend that the Academics Committee of the American Chiropractic Board of Radiology share information regarding learning libraries to allow for a richer learning experience across all campuses.

Having friends and feeling lonely: a daily process examination of transient loneliness, socialization, and drinking behavior.

Loneliness is a well-known indicator of relationship deficits, with potentially severe consequences on health and well-being (Perlman & Peplau, 1981). Research has used cross-sectional methods to examine behavioral consequences of loneliness (e.g., Cacioppo et al., 2002). However, within-person associations between daily fluctuations in loneliness and subsequent behavioral outcomes have yet to be explored. Using a sample of community-dwelling adults, the authors examined associations between daily loneliness on daily time with others, and subsequent context-specific alcohol consumption (i.e., social and solitary consumption), and individual differences in these patterns of behavior. Daytime loneliness significantly and uniquely predicted patterns of social behavior and context-specific consumption; time with others mediated loneliness-social consumption associations, but not loneliness-solitary consumption relationships. These findings contribute to existing literature by demonstrating the unique properties of solitary versus social consumption as behavioral responses to loneliness, thus addressing inconsistent findings regarding the effects of loneliness on alcohol consumption.

Daily affect variability and context-specific alcohol consumption.

INTRODUCTION AND AIMS: Research explored the effects of variability in negative and positive affect on alcohol consumption, specifying daily fluctuation in affect as a critical form of emotion dysregulation. Using daily process methodology allows for a more objective calculation of affect variability relative to traditional self-reports. The present study models within-person negative and positive affect variabilities as predictors of context-specific consumption (i.e. solitary vs. social drinking), controlling for mean levels of affect. DESIGN AND METHODS: A community sample of moderate-to-heavy drinkers (n = 47; 49% women) from a US metropolitan area reported on affect and alcohol consumption thrice daily for 30 days via a handheld electronic interviewer. Within-person affect variability was calculated using daily standard deviations in positive and negative affect. RESULTS: Within person, greater negative and positive variabilities are related to greater daily solitary and social consumption. Across study days, mean levels of negative and positive affect variabilities related to greater social consumption between persons; yet, aggregated negative affect variability was related to less solitary consumption. DISCUSSION AND CONCLUSIONS: Results affirm affect variability as a unique predictor of alcohol consumption, independent of mean affect levels. Yet, it is important to differentiate social context of consumption, as well as type of affect variability, particularly at the between-person level. These distinctions help clarify inconsistencies in the self-medication literature regarding associations between average levels of affect and consumption. Importantly, consistent within-person relationships for both variabilities support arguments that both negative and positive affect variabilities are detrimental and reflect an inability to regulate emotional experience.
