背景“最好的自我”是一种积极的心理学干预，要求参与者写下自己最好的未来。先前的研究已显示其增强幸福感的功效，但其功效背后的机制仍不清楚。目的本研究的目的是分析 BPS 干预文章的内容，并研究该内容与干预措施增加积极情感的功效有何关系。方法参与者 (N = 78) 被随机分配到最佳可能自我条件，或干预的两种变体之一：当前最好的自我和过去最好的自我。对文本进行定性分析，以探讨文章的主题和特征。然后，采用定量和定性数据的混合方法，分析文本内容与干预措施产生的积极情感变化之间的关系。结果发现，不同条件下的作文内容存在显着差异。回归分析表明，不同的变量可以根据情况预测积极情绪的变化。中介分析还发现了条件之间的差异。结论这些发现表明这些干预措施对影响其功效的不同潜在机制做出反应。这项研究有助于更好地理解积极心理学干预如何发挥作用以及如何提高其功效。
BackgroundThe Best Possible Self is a Positive Psychology Intervention which asks participants to write down about themselves in their best possible future. Previous studies have shown its efficacy to enhance wellbeing, but the mechanisms that underlie its efficacy are still unknown.ObjectiveThe aim of this study was to analyze the content of the essays of the BPS intervention and to examine how this content was related to the efficacy of the intervention to increase positive affect.MethodParticipants (N = 78) were randomized to either the Best Possible Self condition, or one of two variants of the intervention: one's best self in the present, and one's best self in the past. Qualitative analyses of the texts were carried out to explore the main themes and features of the essays. Then, a mixed-methods approach with quantitative and qualitative data was followed, in order to analyze the relationship between the content of the texts and the change in positive affect produced by the interventions.ResultsSignificant differences between conditions were found in the content of the compositions. Regression analyses showed that different variables predicted the change in positive affect depending on the condition. Mediation analyses also found differences among conditions.ConclusionsThese findings suggest that these interventions respond to different underlying mechanisms which influence their efficacy. This study contributed to a better understanding of how Positive Psychology Interventions work, and how to increment their efficacy.
