Big Picture,Bad Outcomes: When Visual Perspectives Harm Health Goal Pursuit

People often fail to achieve health goals, which compromises their well‐being. Prior research suggests that seeing events through an observer's eyes (i.e., adopting a third‐person perspective) should facilitate goal pursuit. However, we find that third‐person perspectives discourage goal‐consistent intentions and behavior for health goals when goal centrality is low (i.e., the goal is peripheral to one's self‐concept). In Experiment 1, people who adopted a third‐person perspective chose more sugary foods if they considered a healthy eating goal to be more peripheral to the self. Experiment 2 examines why a third‐person perspective can hinder goal pursuit; it encourages a breakdown in implemental thinking which, in turn, increases negative self‐conscious emotions. While high goal centrality buffers people from negative effects on goal intentions, low centrality does not. Experiment 3 demonstrates that this effect is robust when goal centrality is manipulated. We recommend that consumers pursuing health goals (and individuals who support them) exercise caution when employing perspective‐based strategies, as they may backfire for people at greatest risk of goal abandonment.     

Behavioral changes to repeated takeovers in automated driving: The drivers’ ability to transfer knowledge and the effects of takeover request process

Only a couple of studies evaluated whether drivers of automated vehicles change their takeover behavior when they experience takeover requests repeatedly. Even less evidence was accumulated regarding the question whether drivers are able to transfer learned behavior to takeover situations with varying visibility characteristics and whether drivers’ takeover behavior depends on the takeover process in these situations. This paper therefore examines three research questions. First, it assesses how drivers change their behavior with the repeated experience of a takeover situation with the same visibility (fog or no fog). Second, it tests whether drivers can transfer their learned takeover behavior from a takeover situation with high or low visibility to the same takeover situation with different visibility conditions. Third, it assesses whether drivers’ takeover behavior and their experience of the situation differ between a one-step and a two-step takeover request process. Forty participants experienced a takeover situation three times. Experimental trials varied between-subjects concerning the permanent presence or absence of fog in the adaptation condition, the change of visibility conditions from fog to no fog or vice versa in the transfer condition, and the design of the takeover process with one-step or two-steps. Dependent variables included participants’ takeover time, minimum time-to-collision (TTC_min) with the construction site, deceleration and maximum steering behavior, and their ratings of criticality of the driving situation and perceived effort. Results show that participants adapted their deceleration behavior when repeatedly experiencing a takeover situation with the same visibility characteristics (adaptation condition). Changing these characteristics (transfer condition) lead to increased minimum TTCs, criticality and perceived effort ratings. In general, participants were able to maintain their takeover behavior in takeover situations with varying visibility characteristics indicating that they can transfer their takeover behavior across situations. Finally, the two-step takeover request process was associated with longer takeover times. However, minimum TTCs were larger and maximum steering movements and criticality ratings were lower compared to the one-step process. We conclude that drivers transfer their behavior across takeover situations. However, this performance comes at higher costs in terms of perceived effort and criticality. In addition, two-step takeover request processes should be favored over one-step processes when designing takeover requests. Future studies should examine the validity of the results in various takeover situations and on-the-road studies.     

Should Extremely Premature Babies Get Ventilators During the COVID-19 Crisis?

Abstract

In a crisis, societal needs take precedence over a patient’s best interests. Triage guidelines, however, differ on whether limited resources should focus on maximizing lives or life-years. Choosing between these two approaches has implications for neonatology. Neonatal units have ventilators, some adaptable for adults. This raises the question of whether, in crisis conditions, guidelines for treating extremely premature babies should be altered to free-up ventilators. Some adults who need ventilators will have a survival rate higher than some extremely premature babies. But surviving babies will likely live longer, maximizing life-years. Empiric evidence demonstrates that these babies can derive significant survival benefits from ventilation when compared to adults. When “triaging” or choosing between patients, justice demands fair guidelines. Premature babies do not deserve special consideration; they deserve equal consideration. Solidarity is crucial but must consider needs specific to patient populations and avoid biases against people with disabilities and extremely premature babies.     

Comparing Cognitive Behavioral Therapy and Systemic Therapy for Social Anxiety Disorder: Randomized Controlled Pilot Trial (SOPHO-CBT/ST)

This randomized controlled trial (RCT) aimed to pilot the newly developed manualized and monitored systemic therapy (ST) for social anxiety disorder (SAD), as compared to manualized and monitored cognitive behavioral therapy (CBT). We conducted a prospective multicenter, assessor-blind pilot RCT on 38 outpatients (ICD F40.1; Structured Clinical Interview for DSM (SCID); Liebowitz Social Anxiety Scale, LSAS-SR >30). The primary outcome was level of social anxiety (LSAS-SR) at the end of treatment. A total of 252 persons were screened, and 38 patients were randomized and started therapy (CBT: 20 patients; ST: 18 patients; age: M = 36 years, SD = 14). Within-group, simple-effect intent-to-treat analyses (ITT) showed significant reduction in LSAS-SR (CBT:d = 1.04; ST:d = 1.67), while ITT mixed-design ANOVA demonstrated the advantage of ST (d = 0.81). Per-protocol analyses supported these results. Remission based on reliable change indices also demonstrated significant difference (LSAS-SR: 15% in CBT; 39% in ST;h: 0.550), supported by blind diagnosticians’ ratings of those who completed therapy (SCID; 45% in CBT, 78% in ST,p = .083). No adverse events were reported. CBT and ST both reduced social anxiety, supporting patient improvement with the newly developed ST for SAD; this has yet to be verified in a subsequent confirmatory RCT.     

Mediation of Childhood Adversity and Health by Relationship Quality in Diverse Couples

Individuals with economic disadvantage experience greater (a) adverse childhood experiences (ACE), (b) risk for low relationship quality and relationship dissolution, and (c) disparity in physical and mental health. Thus, a critical need exists to understand the connections between areas of disparity in family and relational health on physical and mental health for those most vulnerable to the deleterious effects. The researchers therefore tested a dyadic model for the mediation of ACE and health by relationship quality with data from 503 couples with economic disadvantage and a racial or ethnic minority background (76.9%). The data fit the proposed model and explained a majority of the variance in health, 82.3% of the variance in menʼs health and 56.5% in womenʼs health—both large effects. Moreover, the significant indirect pathway between ACE and health through relationship quality contributed 98.05% and 57.40% of the total effects for men and women, respectively. Overall, a significant relationship existed between ACE, relationship quality, and health for men and women at the actor-level and the dyadic influence between members of a couple contributed to the overall model fit. Results add to support for the role of relationship quality as a dyadic social determinant of health disparities with implications for prevention and intervention.     

Patterns of marijuana use and physical health indicators among Canadian youth

We examine how trajectories of marijuana use in Canadian youth (ages 15 to 28) are related to physical health indicators in adolescence and young adulthood. Youth were initially recruited in 2003 (N = 662; 48% male; ages 12 to 18) and followed for six waves. Five trajectories of marijuana use (Abstainers-29%, Occasional users-27%, Decreasers-14%, Increasers-20% and Chronic users-11%) were identified. Chronic users reported more physical symptoms, poorer physical self-concept, less physical activity, poorer eating practices, less sleep, and higher number of sexual partners during adolescence than other classes. Decreasers also reported poorer physical self-concept and poorer eating practices than abstainers. Other trajectory classes showed few significant health problems. Chronic users also reported more acute health problems (i.e. serious injuries, early sexual debut, higher number of sexual partners, greater likelihood of having a STI) in young adulthood than all other classes contributing to costs of healthcare. Youth who engage in early, frequent and continued use of marijuana from adolescence to young adulthood are at-risk of physical health problems in adolescence and young adulthood.     

Black Lives Matter: We are in the Same Storm but we are not in the Same Boat

Black Lives Matter is a clarion call for racial equality and racial justice. With the arrival of Africans as slaves in 1619, a racial hierarchy was formed in the United States. However, slavery is commonly dismissed as that less than noble aspect of the United States’ history without really confronting the legacies of racial inequality and racial injustice left in its wake. White supremacy, based on the myths of white superiority and Black inferiority, have obscured racial inequality and racial injustice, resulting in blaming the victims. Using Black Lives Matter as a platform, we focus on some key considerations for theory, research, education, training, and practice in clinical, community, and larger systems contexts. Broadly, we focus on Black Lives Matter, literally; Black dehumanization; historical oppression; healing; and implications for the field of family therapy. More specifically, we draw attention to health disparities, mass incarceration and aggressive policing, intergenerational racial trauma, restorative justice, and antiracist work.     

The Critical Need to Recognize That Families Matter for Adult Health: A Systematic Review of the Literature

A systemic approach to researching families and health should capture the complex network within which family members are embedded, including multiple family relationships and larger systems of health care. However, much of the families and health research focused on adult family members has focused solely on intimate partnerships, usually the marital relationship. This neglects the remainder of the powerfully influencing family relationships adults retain, and may increasingly focus on as they age. We conducted a systematic review of the families and adult health literature, retaining 72 articles which were subsequently thematically coded to highlight main foci of this area of research. Results highlight six themes, which include family relationship quality, family composition, behavioral factors in health and health care, psychophysiological mediators, caregiving, and aging health. Findings support an underrepresentation of family members, other than the intimate partner, in research on adult health.
