The study investigated the long-term effectiveness of the adolescent cognitive behavioral resiliency training Op Volle Kracht (OVK) on the secondary outcomes: anxiety symptoms, hopelessness, happiness, life satisfaction, optimism, coping, self-efficacy, and school functioning. In addition, the study analyzed whether the secondary outcomes moderated the intervention effect on depressive symptoms.
A two-condition (intervention and control) cluster randomized controlled trial was conducted. All adolescents in the 8th grade were eligible to participate, unless they, or their parents, declined their participation. Schools were the unit of randomization. Missing data were imputed and intent to treat analyses were conducted. The results were analyzed using Latent Growth Curve Modeling across the 24-months follow-up period.
The total sample consisted of 1341 adolescents (Mage = 13.91, SD =0.55, 47.3% girls, 83.1% Dutch ethnicity). The intervention and control condition consisted of 634 adolescents from 4 schools and 707 adolescents from 5 schools, respectively. OVK did not have an effect on depression, anxiety, hopelessness, happiness, and life satisfaction, but promoted cognitive coping over the course of the follow-up period. OVK showed small iatrogenic effects on optimism, active coping, social self-efficacy and school grades directly post intervention, but these effects disappeared during the follow-up period. Finally, none of the outcome variables moderated the intervention effect on depressive symptoms.
The universal resiliency training OVK was not effective in this Dutch sample. Implications for research and practice were discussed.

本研究调查了青少年认知行为弹性训练“全力以赴”（Op Volle Kracht，OVK）对次要结果的长期有效性，这些次要结果包括焦虑症状、绝望感、幸福感、生活满意度、乐观主义、应对方式、自我效能感和学校功能。此外，该研究分析了这些次要结果是否调节了干预对抑郁症状的影响。
进行了一项双条件（干预和对照）整群随机对照试验。所有八年级青少年都有资格参与，除非他们或其父母拒绝参与。学校是随机分组单位。对缺失数据进行了插补，并进行了意向性分析。在24个月的随访期内，使用潜在增长曲线模型对结果进行了分析。
总样本包括1341名青少年（年龄中位数=13.91，标准差=0.55，47.3%为女孩，83.1%为荷兰裔）。干预组和对照组分别由来自4所学校的634名青少年和来自5所学校的707名青少年组成。OVK对抑郁、焦虑、绝望感、幸福感和生活满意度没有影响，但在随访期间促进了认知应对。OVK在干预后直接对乐观主义、积极应对、社交自我效能感和学校成绩显示出较小的医源性影响，但这些影响在随访期间消失了。最后，没有一个结果变量调节了干预对抑郁症状的影响。
通用弹性训练OVK在这个荷兰样本中无效。讨论了对研究和实践的启示。
