Self-efficacy versus perceived enjoyment as predictors of physical activity behaviour

Objective: Self-efficacy and physical activity (PA) enjoyment are related to PA behaviour, but it is unclear which is more important and how they interrelate. The purpose of this study was to examine how these two constructs interrelate to influence PA behaviour.

Design: Participants were low-active adults (n = 448) participating in a RCT examining the effect of a PA promotion intervention. Participants completed physical activity, enjoyment and self-efficacy measures at baseline, six and 12 months.

Results: Self-efficacy and enjoyment at both baseline and six months predicted PA at 12 months. However, enjoyment was a stronger predictor than self-efficacy, in that self-efficacy no longer predicted PA behaviour when included alongside enjoyment. In follow-up mediation analyses, enjoyment at six months did not mediate the effect of baseline self-efficacy on 12-month PA; however, six-month self-efficacy mediated the effect of baseline enjoyment on 12-month PA.

Conclusion: Our results indicate that interventions should perhaps initially focus on increasing enjoyment of physical activity. Greater PA enjoyment appears to influence individuals’ self-reported ability to engage in regular PA (i.e. higher self-efficacy ratings). Additional research is needed to better understand the interrelationships between self-efficacy and enjoyment and how these constructs affect PA.     

A moderated mediation analysis of children’s physical activity enjoyment

Grounded in expectancy value theory (EVT), a moderated mediation model predicting children’s physical activity (PA) enjoyment was tested. Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT.     

Does Past Condom Use Moderate the Future Condom Use Intention-Behavior Relationship? Results from a Ghanaian Sample

Behavioral intention is an important predictor of actual behavior. Yet, people often fail to act on their intentions. This study used panel data to examine whether intention interacts with past behavior in determining future behavior. Young people in the Eastern Region of Ghana (N = 956, 495 = female, 461 = male) completed a structured self-administered questionnaire, assessing intentions to use condoms and past condom use behavior at Time 1, and future condom use behavior at Time 2. Hierarchical multiple regression analyses indicated that intentions to use condoms and past condom use behavior accounted for a significant proportion of the variance in future condom use behavior. In addition, past condom use moderated the future condom use intention–behavior relationship. These results demonstrate the usefulness of considering young people's past experiences with condoms in informing the design of condom use skills training. In other words, a condom use skills training intervention that uses the pedagogical approach of starting from the “known” to the “unknown” might benefit young Ghanaians.     

风险认知策略的计算机模拟实验

风险认知策略是个体面临风险情景时的风险认知倾向,可以通过个体的行为策略加以判断。本实验采用计算机模拟风险情景,以严格的２×２×３的实验变量设计,研究个体的风险认知策略与风险情景因素的关系。实验结论表明,风险认知策略的调整与风险情景中的实际风险程度（风险概率）、风险信息类型以及对风险情景可控与不可控性的知觉有关。个体的冒险性倾向是相对稳定的心理特征,但风险认知策略的调整不仅与个体的心理特征有关,还与风险情景因素有关。     

The Psychotherapeutic Encounter: Sexual Acting Out As the Focus of Intervention

Clinical observation indicates that sexual acting out takes place during periods in which the integrity of the self is threatened by some disappointment, some frustration, or what is perceived as an unavoidable but unfair demand. Rather than confront the problem within the object relationship, the conflict is acted out. The sexual encounter reduces anxiety and facilitates the containment of depressive and aggressive feelings. Self-integration is attempted even at the risk of losing something, be it a wife, a husband, a girlfriend or the presidency. At the time it seems the only possible way to cope with painful or threatening stimuli.     

青少年的性节制：生活史的观点

生活史是研究身体发育与后代繁衍时间表的一种进化方法。本研究根据生活史理论调查与分析了13000余名“婚前节欲”性教育规划中青少年的性态度、性信念与性行为关系。因子分析结果显示,多种性信念和性态度可以整合成一个一般因子,性节制。可以假设,性节制是生活史策略的一个维度。性节制的表现主要包括：性自我克制的意愿、承认性抑制的个人和社会原因、积极肯定青少年的节欲行为、否认性行为的积极影响、回绝性行为的技能、以健康为由赞同性抑制,以及对宗教的虔诚与笃信等。研究结果显示,性节制因子上的低分与更频繁性行为有关,年龄与性别变量对二者关系没有影响。本文还探讨了性态度、性行为以及人类生活史间的关系     

SPACE AND TIME FROM A NEO‐WHITEHEADIAN PERSPECTIVE

Russell Stannard distinguishes between objective time as measured in theoretical physics and subjective time, or time as experienced by human beings in normal consciousness. Because objective time, or four‐dimensional space‐time for the physicist, does not change but exists all at once, Stannard argues that this is presumably how God views time from eternity which is beyond time. We human beings are limited to experiencing the moments of time successively and thus cannot know the future as already existing in the same way that God does. I argue that Stannard is basically correct in his theological assumptions about God's understanding of time but that his explanation would be more persuasive within the context of a neo‐Whiteheadian metaphysics. The key points in that metaphysics are (1) that creation is contained within the structured field of activity proper to the three divine persons of the Christian doctrine of the Trinity and (2) that the spontaneous decisions of creatures are continually ordered and reordered into an ever‐expanding totality already known in its fullness by the divine persons.     

The Driving Anger Expression Inventory: A Validity Study with Community College Student Drivers

This study explored the relationship of driving anger expression to driving anger, trait anger, general anger expression, and aggressive and risky behavior while driving. Verbal, physical, and vehicular forms of expressing anger while driving correlated positively with each other, driving and trait anger, anger-in, and anger-out and negatively with adaptive/constructive driving anger expression and general anger-control. Adaptive/constructive expression formed small negative correlations with these measures, except for a positive correlation with anger-control. Regression models controlling for demographic variables and driving anger, trait anger, or general anger expression demonstrated forms of driving anger expression added variance to predicting aggressive and risky behavior. Forms of driving anger expression partially mediated the effects for driving anger, trait anger, and general anger expression on aggressive and risky behavior. No moderation effects were found for age, gender, or miles driven. Findings provided evidence for convergent and incremental validity for the Driving Anger Expression Inventory.
