The purpose of this study was to assess the impact of deliberate acts of kindness (DAKs) plus access to a stress management booklet (intervention), compared to the booklet alone (control) on the stress-related outcomes of resilience, social interaction anxiety, affect, and mood of undergraduate and graduate students. Participants’ study-related experiences were also explored, as were the types of DAKs. This repeated-measures, randomized controlled trial included 112 students (80 undergraduate and 32 graduate) with 56 in each condition. Four previously validated scales were implemented at baseline, immediate post-intervention, and 3-months post-intervention. A linear mixed effects model was utilized with group and time entered as fixed effects. Content analysis of open-ended question responses and DAKs logs was conducted. The KISS of Kindness II had a statistically significant interaction effect on the intervention group participants’ resilience (p = 0.0099), social anxiety (p = 0.0016), and negative affect (p = 0.0033), but had no significant impact on their positive affect or mood. Intervention participants described improvements in mental wellbeing. DAKs were plentiful (1,542 DAKs, 26 types), and show promise for university-based mental health interventions.

这项研究的目的是评估故意的善意行为（DAK）以及获得压力管理手册（干预）的效果，与仅将手册（对照）相比，对适应力，社交互动焦虑，本科生和研究生的情感和情绪。还探讨了参与者的学习相关经验，以及DAK的类型。这项重复测量的随机对照试验包括112名学生（80名本科生和32名研究生），每种情况下有56名。在基线，干预后即刻和干预后3个月采用了四个先前验证的量表。利用线性混合效应模型，将组和时间输入为固定效应。进行了开放式问题回答和DAK日志的内容分析。p  = 0.0099），社交焦虑（p  = 0.0016）和负面影响（p  = 0.0033），但对他们的正面影响或情绪没有显着影响。干预参与者描述了心理健康方面的改善。DAK丰富（1,542 DAK，26种类型），并显示出对基于大学的心理健康干预措施的希望。
