Predicting sun-protective intentions and behaviours using the theory of planned behaviour: a systematic review and meta-analysis

Objective: To synthesise theory of planned behaviour (TPB) relationships, using meta-analysis, and test the predictive utility of the model for sun protection behaviour.

Design: Thirty-eight samples were identified via database/manual searches and academic society posts based on the criteria: measuring sun-protective intentions and/or prospective behaviour; using the TPB/theory of reasoned action as a basis of measurement; and providing bivariate correlations for at least one relevant TPB association.

Main outcome measures: Sun-protective intentions and behaviours.

Results: The sample-weighted average effects were moderate-to-strong with attitudes showing the strongest association with intention (r+ = 0.494), followed by perceived behavioural control (PBC; r+ = 0.451), and subjective norm (r+ = 0.419). Intentions showed a stronger association with prospective behaviour (r+ = 0.486) compared to PBC (r+ = 0.314). A total of 39% of variance in intentions and 25% of variance in behaviour were explained. Publication bias was not evident. Moderator analyses showed that TPB associations were stronger when measures specified the Target, Action, Context and Time; in non-student samples; and when follow-up exceeded two weeks.

Conclusion: Despite recent criticism, this review shows that the TPB explains a large amount of variance in sun protection and that TPB associations are robust across different populations.     

The moderating impact of temporal separation on the association between intention and physical activity: a meta-analysis

Previous meta-analyses have estimated that the intention–behaviour association in physical activity (PA) is large in magnitude. However, these prior meta-analyses have also revealed a large degree of heterogeneity, suggesting the presence of moderating variables. This study examines the impact of one such moderator, testing the hypothesis that the magnitude of the association between intention and behaviour decreases as the temporal separation between the two increases. A systematic literature search was used to identify published and unpublished studies that met the inclusion criteria. A random-effects meta-regression was conducted to test the study hypothesis. A total of 78 journal articles and 11 unpublished dissertations were identified, yielding 109 effect sizes. The mean number of weeks between the measurement of intention and behaviour was 5.4 (SD = 6.6, range = .43, 26). The average correlation between intention and behaviour was r = 0.51. In line with theoretical predictions, temporal separation was a significant moderator of the intention–behaviour correlation (B = ?.014, p < .001) and explained 24% of the between-study variance. This result remained unchanged when entered simultaneously with several control variables. The results of this analysis have important implications both for researchers and for intervention designers aiming to increase rates of PA.     

On having very long arms: how the availability of technological means affects moral cognition

Modern technological means allow for meaningful interaction across arbitrary distances, while human morality evolved in environments in which individuals needed to be spatially close in order to interact. We investigate how people integrate knowledge about modern technology with their ancestral moral dispositions to help relieve nearby suffering. Our first study establishes that spatial proximity between an agent's means of helping and the victims increases people's judgement of helping obligations, even if the agent is constantly far personally. We then report and meta-analyse 20 experiments elucidating the cognitive mechanisms behind this effect, which include inferences of increased efficaciousness and personal involvement. Implications of our findings for the scientific understanding of ancestral moral dispositions in modern environments are discussed, as well as suggestions for how these insights might be exploited to increase charitable giving. Our meta-analysis provides a practical example for how aggregating across all available data, including failed replication attempts, allows conclusions that could not be supported in single experiments.     

The exploratory and confirmatory factor analyses of two subjective career success instruments

This study investigated the psychometric properties of two subjective career success instruments within the South African context: Perceived Career Success (PCSS: Gattiker &; Larwood, 1986 Gattiker, U. E., &; Larwood, L. (1986). Subjective career success: A study of managers and support personnel. Journal of Business and Psychology, 1(2), 78–94. http://dx.doi.org/10.1007/BF01018805[Crossref] , [Google Scholar]) and Life Success Measures Scale (LSMS: Parker &; Chusmir, 1992 Parker, B., &; Chusmir, L. H. (1992). Development and validation of a life-success measures scale. Psychological Reports, 70(2), 627–637. http://dx.doi.org/10.2466/pr0.1992.70.2.627[Crossref], [Web of Science ®] , [Google Scholar]). Data were collected via a convenient sample of 708 South African Police Services (SAPS) personnel (females = 36.8%; Sotho language = 62.50%). Exploratory factor analysis (EFA) was conducted on both instruments, followed by confirmatory factor analyses (CFA). Both instruments showed acceptable construct validity and reliability of scores.     

视觉单通道还是视听双通道?——通道效应的元分析

多媒体学习中的通道效应认为,学习者对"画面+声音解说"组成的视听双通道材料的识记或理解效果要好于"画面+视觉文本"组成的视觉单通道材料,而逆转通道效应则发现了与之相反的结果。针对以往研究缺陷,重新采用元分析技术,以保持测验和迁移测验作为结果变量,考察通道效应的稳定性。经文献检索、纳入与排除后,共获91篇符合元分析的文献。经数据事先合并处理后,保持测验上生成94个独立效应量(8088人),迁移测验上生成83个独立效应量(6664人)。主效应检验发现:视听双通道在保持测验(d=0.24)和迁移测验(d=0.25)上均显著高于视觉单通道;调节效应检验发现:呈现步调、画面动态性和材料时长在保持测验和迁移测验上均对通道效应起到调节作用,通道效应主要在系统步调(d_(保持)=0.43,d_(迁移)=0.44)、动态画面(d_(保持)=0.50,d_(迁移)=0.59)及短时材料(d_(保持)=0.38,d_(迁移)=0.33)条件下出现;所有结果均未发现逆转通道效应。结论认为:相比视觉单通道,当图文信息以视听双通道呈现时更有利于促进学习者对多媒体学习材料的识记和理解,支持了多媒体学习认知理论;呈现步调、画面动态性以及材料时长是通道效应的重要边界条件。     

Acceptance- and mindfulness-based interventions for the treatment of chronic pain: a meta-analytic review

The number of acceptance- and mindfulness-based interventions for chronic pain, such as acceptance and commitment therapy (ACT), mindfulness-based stress reduction (MBSR), and mindfulness-based cognitive therapy (MBCT), increased in recent years. Therefore an update is warranted of our former systematic review and meta-analysis of studies that reported effects on the mental and physical health of chronic pain patients. Pubmed, EMBASE, PsycInfo and Cochrane were searched for eligible studies. Current meta-analysis only included randomized controlled trials (RCTs). Studies were rated for quality. Mean quality did not improve in recent years. Pooled standardized mean differences using the random-effect model were calculated to represent the average intervention effect and, to perform subgroup analyses. Outcome measures were pain intensity, depression, anxiety, pain interference, disability and quality of life. Included were twenty-five RCTs totaling 1285 patients with chronic pain, in which we compared acceptance- and mindfulness-based interventions to the waitlist, (medical) treatment-as-usual, and education or support control groups. Effect sizes ranged from small (on all outcome measures except anxiety and pain interference) to moderate (on anxiety and pain interference) at post-treatment and from small (on pain intensity and disability) to large (on pain interference) at follow-up. ACT showed significantly higher effects on depression and anxiety than MBSR and MBCT. Studies’ quality, attrition rate, type of pain and control group, did not moderate the effects of acceptance- and mindfulness-based interventions. Current acceptance- and mindfulness-based interventions, while not superior to traditional cognitive behavioral treatments, can be good alternatives.

自恋与攻击性关系的元分析

本研究采用元分析技术探讨自恋与攻击性的关系。通过文献检索和筛选, 共纳入原始文献121篇, 含177个独立样本, 参与者总数达73687名。元分析的结果显示, 自恋与攻击性存在显著正相关, 二者关系受性别和自恋报告方式的调节, 但不受攻击性报告方式和文化的调节。同时, 不同类型的自恋与攻击性呈现出不同的相关程度, 内隐自恋与攻击性的相关程度高于外显自恋, 非适应性自恋与攻击性的相关程度高于适应性自恋。后续的研究应加强自恋测量的准确性, 注重探讨不同类型自恋与不同类型攻击性的关系。     

我国内地教师主观幸福感的变迁(2002~2019)：横断历史研究的视角

教师主观幸福感作为衡量教师群体心理健康状况的一项关键指标, 对其现状的调查和分析至关重要, 同时, 对其随社会变迁的动态变化趋势、及其与社会变迁的关系的监测也不可忽视。本研究对2002至2019年间的51篇采用总体幸福感量表(GWB)测量教师主观幸福感的研究报告(共包括13600名教师)进行横断历史的元分析。研究发现：(1)教师主观幸福感均值与年代呈显著负相关, 这说明我国教师主观幸福感在逐年下降。(2)来自社会经济条件(居民消费水平、房价、老年抚养比和教育经费)、社会联结(家庭规模数、离婚率和城镇化水平)和社会威胁(犯罪率)三方面的8项宏观社会指标的变化能显著预测教师主观幸福感的下降。(3)中小学教师的主观幸福感随年代下降的趋势更明显, 其主观幸福感得分要显著低于高校教师。本研究不仅探究了我国教师主观幸福感近20年的变迁趋势, 而且结合社会宏观发展的指标, 提出了影响我国教师主观幸福感的三维理论框架, 对群体社会心理的研究思路进行了纵向(随时代变迁)及横向(宏观社会指标)的拉伸, 拓展理论基础的同时, 在实践上, 为干预调节我国教师群体主观幸福感提供决策依据。     

基于正念的干预与自我同情的关系：一项元分析

运用元分析方法对国内外有关基于正念的干预与自我同情的关系问题进行了探讨, 通过文献检索, 纳入文献65篇, 总样本量为8103。异质性检验发现, 选择随机效应模型比较合适; 敏感性分析显示, 使用One-study removed逐步删除异质性较高研究, 基于正念的干预与自我同情呈显著正相关; 次群体检验表明, 基于正念的干预与自我同情关系受对比方式的调节与影响, 但不受群体和测量工具的影响。研究结果表明, 正念对自我同情水平会产生不同程度的积极影响, 同时随着对比方式的不同对基于正念的干预与自我同情的关系会产生不同的调节作用, 而群体和测量工具对基于正念的干预与自我同情的关系并无调节效应。
