Bullying and mental health problems are pressing concerns for adolescents. Given their burden, we need to find efficacious ways to prevent these experiences. However, existing prevention programs tend to be single-issue and may not focus on the universal capacities required to reduce these problems among youth. To this end, we evaluated the universal, small groups Healthy Relationships Plus (HRP) program, which focuses on the promotion of positive mental health and the reduction of bullying and substance misuse. A sample of 212 youth from Southwestern Ontario were randomly assigned to the HRP or an attention-control condition over an 8-day period during summer 2014. Primary outcome measures (i.e., most important outcomes for this evaluation) were positive mental health, bullying victimization/perpetration, and substance misuse (alcohol, marijuana). We also examined a mediator (help-seeking) and two moderators (sex, adverse childhood experiences) of main effects. Participation in HRP was associated with reduced odds of physical bullying victimization at 1-year follow-up, compared with adolescents in the attention-control condition. This finding was mediated by increased intention to seek help from a mental health professional following HRP participation. We did not find main effects for positive mental health or substance misuse in this sample; however, there was an interaction effect whereby youth with significant trauma experiences reported less marijuana use at 1-year follow-up compared with control students. Findings reiterate the importance of help-seeking for bullying prevention and demonstrate the preliminary efficacy of the HRP as a universal strategy for preventing bullying victimization among mid-adolescents within school and community settings.

青年普遍健康关系促进计划的初步随机对照评估

欺凌和心理健康问题是青少年迫切关注的问题。考虑到他们的负担，我们需要找到有效的方法来防止这些经历。但是，现有的预防方案往往只是一事而已，而可能不会侧重于减少青年中这些问题所需的普遍能力。为此，我们评估了普遍的小型团体“健康关系加”（HRP）计划，该计划的重点是促进积极的心理健康以及减少欺凌和滥用药物的行为。在2014年夏季的8天中，从安大略省西南部的212名青年样本中被随机分配到HRP或注意力控制状态。主要结局指标（即，该评估最重要的结局）是心理健康，欺凌受害/犯罪和滥用毒品（酒精，大麻）。我们还研究了主要影响的调解人（寻求帮助）和两名调解人（性，不利的儿童经历）。与在注意力控制状态下的青少年相比，参加HRP与1年随访时身体欺凌受害几率降低有关。在HRP参与之后，这一发现是由越来越多的寻求心理健康专业人士帮助的中介。在该样本中，我们未发现对积极的心理健康或药物滥用产生主要影响；但是，有一种相互作用的影响，即具有严重创伤经历的年轻人在一年的随访中报告的大麻使用量少于对照组的学生。
