Trust and intention to use autonomous vehicles: Manufacturer focus and passenger control

Autonomous Vehicle (AV) research has focused on public acceptance of and intention to use AVs, with trust emerging as important to these variables. Research on AV trust has centered on trust in vehicle performance. However, trust evaluation may include AV manufacturers and developers, and regulation pertaining to AVs; thus, we expand our measurement of trust to include beliefs based on manufacturers and regulation. In this experiment, we manipulate information regarding manufacturer focus (i.e., an emphasis on standards, regulations, and research (SRR) versus speed to market) to determine its effect on trust. When information focused on SRR, we found higher levels of trust in AV performance and in manufacturers, compared to when it focused on speed to market. In addition, information regarding passenger control (i.e., the ability to take over for the vehicle and to determine privacy settings) was manipulated to yield either high or low passenger control conditions. Behavioral Intention (BI) to use AVs was lowest when speed to market was emphasized and when passenger control was low. Furthermore, trust was tested as a mediator between perceived risk and BI. Trust in AV performance partially mediated the relationship between perceived AV performance risk and BI. In addition, trust in AV regulation partially mediated the relationship between AV privacy/security risk and BI. Researchers should continue to examine trust beyond the AV itself to encompass trust in manufacturers and regulations. Those designing and marketing AVs should carefully consider decisions that influence manufacturer/developer reputation and passenger control due to their effect on intention to use AVs.     

Evaluating driver comprehension of the roadway environment to retain accountability of safety during driving automation

Driver comprehension is a substantial component of situation awareness that involves the ability of an individual to understand the significance of an object, traffic sign, or hazard while driving. An increase in crashes related to autonomous driving systems has raised a concern regarding the safety of other roadway users due to the diminishing accountability resulting from a general lack of understanding of the limitations or disregard of the safety protocols by users. To keep drivers vigilant when engaged in partial automated systems, a methodology to monitor real-time driver comprehension was proposed. A driving simulator study consisting of 90 participants, equally split between males and females, was executed to establish driver comprehension in six different variations of driving difficulty. Joint probability density functions were created by considering percent time spent gazing, answers to probe questions, and driving performance. Based on these density functions, five levels of comprehension were devised and assigned thresholds. Overall, as task difficulty increased, a non-linear deterioration in driving speed along with an increase in total gaze duration was observed before comprehension was attained. A two-step validation protocol was also proposed to ensure similar levels of comprehension to non-automated driving from the human driver, when engaged in early forms of automation. The proposed real-time driver comprehension monitoring constitutes a first step toward developing a methodology to reinstate the accountability of safety of other roadway users when engaged in driver-in-the-loop automation systems.     

Mental health of circus artists: Psychological resilience,circus factors,and demographics predict depression,anxiety, stress,and flourishing

Circus artists perform physically demanding skills in a high-stress environment, yet little is known about their mental health. We explored emotional states of depression, anxiety, stress and flourishing in a sample of 500 circus artists. The predominantly female sample (n = 415) encompassed a range of performance levels (amateur 50%, part/full-time professional 41%, student 6%, retired 3%), with aerial acrobatics (71%) being the most frequently represented main circus discipline in the sample. Compared to previously established normative scores of a non-clinical population, circus artists scored higher on scales of emotions reflecting depression, anxiety, and stress, and lower on flourishing. They also scored higher on both state and trait resilience compared to previously established normative scores. Using a Bayesian estimation procedure, linear regression analyses showed that resilience, circus factors, and demographics (i.e., age and gender) explained between 24% and 51% of the variance in emotional states of depression, anxiety, stress, and flourishing. Consistently, circus artists with higher levels of state/trait resilience reported higher levels of psychological wellbeing, indicated by lower levels of emotional states of depression, anxiety and stress, and higher levels of flourishing. Therefore, the development of interventions for circus artists who experience lower levels of psychological wellbeing appears warranted.     

Exercise is medicine… when you enjoy it: Exercise enjoyment,relapse prevention efficacy,and health outcomes for youth within a drug and alcohol treatment service

ObjectiveEvidence for the effectiveness of exercise as therapy for youth substance use disorder (SUD) is scarce. In this study, we investigated associations between exercise enjoyment and recovery outcomes for youth undergoing residential SUD treatment.MethodUsing ecological momentary assessment, each week participants reported perceptions of exercise enjoyment, relapse prevention efficacy, self-esteem, and physical health, and associations between these variables were assessed at both between- and within-person levels. There were 97 participants (age: M = 17.5, SD = 1.57, range = 14 to 21; 37 female, 60 male), with a final sample of 64 due to participants (n = 33) discontinuing treatment within 2 weeks of commencement. Of the remaining sample, 50% (n = 32) completed 3 or more assessments, 40% (n = 26) completed 5 or more, and 25% (n = 16) completed 7 or more.ResultsRelapse prevention efficacy, self-esteem, and perceived physical health increased over time in the program. Youth who, on average, enjoyed exercise more had higher self-esteem, perceived physical health, and relapse prevention efficacy than those who enjoyed it less. Additionally, on occasions when youth enjoyed exercise more (relative to their own average), they reported higher self-esteem, perceived physical health, and relapse prevention efficacy than on occasions when they reported enjoying it less.ConclusionParticipation in—and importantly, enjoyment of—exercise was linked to key health indices and predictors of relapse for youth during SUD treatment. These findings demonstrate that participation in enjoyable structured exercise may provide an important component of successful SUD treatment.     

寻找镜中的自我：精神分裂症患者的视觉观点采择

精神分裂症患者的视觉观点采择影响其必要的社交活动和生活质量。本文通过对精神分裂症患者视觉观点采择的研究进行梳理,总结出相关的心理特点：精神分裂症患者的视觉观点采择过程受损,表现出自我中心性和他人中心性。在神经生理上表现出与视觉观点采择相关的脑区激活减弱。可能的原因是患者认知功能中反应抑制能力和心理旋转能力的受损所致,建议采用认知干预疗法可能会改善患者的视觉观点采择能力。目前的研究论证了精神分裂症患者视觉观点采择过程的损伤,对于不同水平的视觉观点采择下精神分裂症患者的认知模式还未有明确的定论,未来的研究可以从该角度入手,更加明确精神分裂症患者不同水平视觉观点采择的特点和神经生理活动。     

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

Relationships Among Emerging Adult Psychological Problems,Maltreatment, and Parental Psychopathology: Moderation by Parent–Child Relationship Quality

Current research supports clear relationships between parental psychopathology, parental maltreatment, and emerging adult child psychopathology. Less research has examined how the role of the parent–child relationship influences these existing associations. The current study tested two models that examined the moderating effect of parent–child relationship quality on parental psychopathology and emerging adult mental health as well as the effect on parental maltreatment and emerging adult mental health. It was expected that high parent–child relationship quality would buffer against the negative effects of parental psychopathology and maltreatment while enhancing the effects of functional parenting characteristics. Participants included 1,452 emerging adults, predominantly Caucasian (73.3%) college students who completed surveys on their mental health, recent experienced maltreatment, and their parents’ mental health problems. Results suggested lowest rates of mental health problems for emerging adults were associated with higher parent–child relationship quality and lower parental psychological problems, whereas negative outcomes were associated with higher parental psychopathology, regardless of parent–child relationship quality. Additionally, physical maltreatment was associated with lower rates of mental health concerns in the context of higher mother-daughter relationship quality. Results emphasize the continuing impact of the parent–child relationship, particularly the mother-daughter relationship, on emerging adults’ mental health. Moreover, the current study demonstrates the continuing influence of parents on their emerging adult children.     

Continuum between Relational and Therapeutic Models of Self-help in Mental Health: A Qualitative Approach

Self-help groups are generally described as “group[s] composed of individuals who meet on a regular basis to help one another cope with a life problem” (APA, 2019). Yet, it is challenging to find a univocal definition of self-help groups. Scholars usually use different labels to highlight various features of self-help groups, suggesting the need for further inquiry regarding commonalities and differences. The level of professional involvement is one of the most disputed factors influencing whether a group is considered to belong to the “self-help family.” The present qualitative study aimed to understand how professional support in Tuscany, Italy can influence the organizational choices of these groups (place for meetings, admission criteria, timing, etc.), as well as the personal beliefs of members. The study included 17 self-help groups. During 13 focus groups meetings, 92 participants were interviewed; then, we individually interviewed 19 facilitators and six additional key informants from mental health settings. We used a grounded theory approach, and we discussed the emerging models with participants at a public event. Results show the emergence of two theoretical models to define self-help groups, not to be interpreted as mutually exclusive. The “relational model” refers to self-help groups whose main feature is to guarantee the acquisition of specific skills (social comparison skills, active listening, and empathy), while the “therapeutic model” seems to represent a kind of assimilation of other types of interventions.     

Racialized Sexual Discrimination (RSD) in the Age of Online Sexual Networking: Are Young Black Gay/Bisexual Men (YBGBM) at Elevated Risk for Adverse Psychological Health?

Young Black gay/bisexual men (YBGBM) are a highly marginalized population across multiple health outcomes. Most research on YBGBM health has focused on HIV/sexual health, but there is a demonstrable need for research examining racism and psychosocial functioning among this population. Racialized Sexual Discrimination (RSD), also known as sexual racism, is an important but under-investigated phenomenon that may have implications for the psychological health and well-being of YBGBM. This paper provides an overview of empirical research on RSD as experienced by gay/bisexual men of color in online partner-seeking venues. First, the researchers discuss how racialized experiences are a documented online phenomenon, with a variety of manifestations, and identify the potential effects that this phenomenon may have on the psychosocial health of YBGBM, and gay/bisexual men of color as a whole. Second, the researchers synthesize the RSD literature with a broader literature examining psychological well-being across race and sexual orientation. Third, the researchers present a theoretically grounded conceptual model detailing the pathways between RSD and psychological well-being using a stress and coping framework. The paper concludes with recommendations for future research on this topic, including scale development and hypothesis testing.
