Understanding physical activity declines during COVID-19: The affective repercussions of disruption to exercise routines

Recent research has examined psychological factors that forestalled declines in physical activity (PA) during the early stages of the COVID-19 pandemic. Surprisingly, there has been limited evidence of an association between intrinsic motivation (IM) and PA. We reasoned that IM may have not predicted PA because COVID-19 restrictions limited opportunities to engage in exercise in ways that produced positive affective experiences (i.e., inherent rewards). Using data from a cross-sectional survey (N = 373 participants), we tested a moderated mediation model that predicted perceived changes to affective experiences during exercise would mediate the association between disruption to one’s exercise routine and self-reported declines in PA, and that effects would be moderated by IM. Evidence of moderated mediation was found, suggesting that disruptions to exercise routines were associated with fewer positive affective experiences during exercise that predicted declines in PA engagement, especially for people who typically exercised for intrinsic reasons.     

Effects of behaviour change interventions on physical activity in people with spinal cord injury: A systematic review and meta-analysis

ObjectivesThis review investigated the effectiveness of behaviour-change interventions to improve physical activity (PA) participation in individuals with a spinal cord injury. Additionally, the review sought to analyse the change in PA behaviour that might be expected by utilising behaviour change in PA interventions and what specific intervention characteristics, application of behaviour change theories, and behaviour change techniques are most efficacious.MethodsThe protocol was prospectively registered on PROSPERO: CRD42021252744, and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed in this review. Eight databases were comprehensively searched using a well-defined strategy developed in collaboration with an academic liaison librarian. Randomised, non-randomised controlled, and non-controlled studies were included in this review; however, controlled and non-controlled studies were analysed separately. Studies were included if participants were older than 16 years and had an SCI of any cause, level or severity, regardless of the time since injury. The behaviour change technique taxonomy version 1 was used to code the intervention characteristics for behaviour modification. The combined effects across studies were pooled in a meta-analysis, and the risk of bias was assessed using the Cochrane Risk of Bias 2 tool.ResultsThe search retrieved 10,155 titles and abstracts. After duplicate removal and screening against the eligibility criteria, 23 studies were included. The overall effect estimate of the change in PA participation in the controlled trials post-intervention was medium (d = 0.50, 95% CI = 0.31–0.70) in favour of behaviour-targeted interventions. The mean difference in PA volume between pre- and post-intervention was an increase of 22 minutes per week (95% CI = 5.96–38.90). Interventions that provided practical support (d = 0.81, 95% CI = 0.46–1.16), which were individualised (d = 0.62, 95% CI = 0.34–0.90) and that utilised monitoring (d = 0.59, 95% CI = 0.34–0.83) had a greater effect on change to PA than those that were group-based and did not utilise those specific techniques.ConclusionsInterventions that target behaviour change to increase PA in people with SCI appear effective. Utilising behaviour change frameworks and specific behaviour change techniques augments PA uptake and levels, and interventions aimed at improving PA in people with SCI should incorporate a behaviour modification component. More research is needed on the isolated effect of intervention structure parameters and specific behaviour change techniques.     

An ecological momentary assessment study of affectively-charged motivational states and physical activity

The physical activity (PA) intention-behavior gap has prompted researchers to explore other explanatory factors such as affective mechanisms which might better explain PA engagement. Affectively-charged motivations (e.g., desire, dread) are thought to influence the pursuit or avoidance of future behavior. This study examined whether affectively-charged motivations for PA changed across the day and were differentially associated with PA intensity. Participants (N = 60) wore ActiGraph GT3X accelerometers and answered EMA (M = 134.7 prompts/person) about affectively-charged motivations for upcoming PA using a 0-to-100-point scale (dread-excitement) in the morning, pre-activity, at-random, and evening for 14 days. Affectively-charged motivations for PA were lower in the morning and at-random compared to pre-activity (p = .004) and evening (p < .001). On average, individuals who rated morning affectively-charged motivations for PA 10-points higher engaged in 28 additional min/week of moderate-to-vigorous PA (p = .048). These findings suggest that affectively-charged motivations occurring in the morning may have greater salience for PA.     

希望思维在临床与实践领域的应用、特点与启示

摘 要 自Snyder提出以来,希望思维的认知理论已经发展了20余年,它在世界各地的不同领域都得到了广泛认可,将其应用于临床领域则成为近年来的热点。大量研究表明系统的训练可以促使希望思维产生和提高,从而帮助个体改善生理疾病和心理疾病,矫正不良行为。与此同时,希望思维能够用于帮助个体更好地应对压力情景,促进积极心理健康,帮助其更好的成长。总的来说,希望思维的临床应用具有适用范围广泛、干预方法相对简单易行、可以作为独立的希望干预系统和也能与传统心理治疗相融合四个特点。未来对希望思维在临床领域的应用与研究一方面要注重对新的本土化的干预策略的开发,另一方面要注重对其内部作用机制的研究和应用。     

感同身受的社会痛苦：来自神经影像学的证据

社会痛苦是指个体感觉到被渴望的社会关系排斥或者被重要他人和群体贬损时表现出的一种特定的负性情绪反应。对于社会痛苦的神经生理机制的探讨已成为当前研究的重点, 研究者主要从个体经历社会排斥、目睹他人被社会排斥(共情)时的神经活动来解释社会痛苦的神经生理机制。社会痛苦受到依恋、自尊等因素的影响。未来可从探讨社会痛苦在不同年龄阶段的神经机制和探索社会痛苦与人格障碍之间的关系两个方面展开进一步的探究。     

Dimensions of Pediatric Procedural Distress: Children's Anxiety and Pain During Immunizations

The purpose of this study was to isolate and compare children's procedural anxiety and pain. The study was conducted in a school-based pediatric health clinic with 39 fourth graders receiving 3 injection vaccinations over a 6-month period. Child and nurse ratings and an observational scale assessed anxiety and pain. Results suggest that anxiety and pain are highly correlated, however self-report and an observational measure discriminate between these constructs. Self-report and observational measurement indicated more pediatric pain than anxiety, whereas nurse reports did not indicate differences between children's pain and anxiety.

Hurt feelings and four letter words: Swearing alleviates the pain of social distress

Methods for alleviating physical pain are increasingly found to attenuate social pain. Recent evidence suggests that swearing may attenuate sensitivity to physical pain. This study examined whether swearing similarly attenuates two consequences of social distress: social pain and exclusion‐induced hyperalgesia. Sixty‐two people wrote about an autobiographical experience of exclusion or inclusion. Then they repeated a swear or neutral word for 2 minutes followed by measures of social and physical pain. Excluded non‐swearers reported feeling more social pain and greater sensitivity to physical pain compared with included non‐swearers. Excluded swearers reported less social pain than excluded non‐swearers and no heightened sensitivity to physical pain. The findings suggest that social and physical pain are functionally similar and that swearing attenuates social pain.
