Minority stress has been posited as a framework to explain the health disparities seen in sexual minority youth, including lesbian, gay, bisexual (LGB+) youth. In the present study, psychological inflexibility was investigated as a moderator in the relationship between minority stress and two harmful youth outcomes: substance misuse and suicidality. Analyses showed significant interactions indicating moderating effects in the substance misuse models but not in the suicidality models. A positive direct effect of global psychological inflexibility on suicidality was also discovered. Analyses exploring the moderating effects of psychological inflexibility's sub-processes found that cognitive fusion and obstruction of valued living had significant, positive interactions with minority stress in relation to substance misuse. No moderating effects were found within models exploring the sub-processes on suicidality; however, positive direct effects were indicated between cognitive fusion and suicidality as well as between obstruction of valued living and suicidality. Overall, results suggest that psychological inflexibility is a promising moderator variable that could potentially be targeted via intervention in LGB + adolescents and therefore warrants further study with this population.

少数族裔的压力已被视为解释性少数年轻人（包括女同性恋，男同性恋，双性恋（LGB +）青年）中健康差异的框架。在本研究中，研究者在少数群体压力与两种有害的青年结果（滥用药物和自杀）之间的关系上作为主持人，研究了心理僵硬。分析表明，显着的相互作用表明在物质滥用模型中有调节作用，而在自杀模型中则没有。还发现全球心理僵化对自杀具有积极的直接影响。分析探索心理僵化的子过程的调节作用的分析发现，认知融合和有价值生活的阻碍与滥用药物相关的少数群体压力具有显着的积极相互作用。在探索自杀性子过程的模型中未发现任何调节作用。然而，在认知融合和自杀之间以及对有价值的生活和自杀的阻碍之间都显示出积极的直接影响。总体而言，结果表明，心理僵硬是一个有前途的调节变量，可以通过干预LGB +青少年来针对，因此有必要对该人群进行进一步研究。
