Multiple internal factors, such as psychological resilience and mental health status, have been shown to contribute to overall quality of life (QoL). However, very few studies to date have examined how these factors contribute to QoL of youth and young adults in a stressful situation. Here, we studied the contribution of these factors, as well as of ecological momentary mood assessment, to QoL of young army recruits during their Basic Training Combat (BCT). To this end, we collected data from 156 male and female soldiers in a mixed-gender unit in the Israel Defense Forces (IDF). Using a mobile app installed on participants' phones, participants provided self-reports regarding their mental health status and psychological resilience at baseline, and QoL 2 weeks later. Momentary mood reporting was further collected during the 2-week interval period using a daily self-report mood scale (IMS-12). Structural equation modeling (SEM) was used to examine the interrelationships among the study variables based on a hypothesized model. We found that a model with all factors (gender, resilience, mental health status and momentary mood) provided a good fit for the data based on its fit indices [χ(38) = 47.506, = 0.139, CFI = 0.979, NFI = 0.910, RMSEA = 0.040, TLI = 0.964]. However, the only direct contributors to QoL were gender and momentary mood, accounting together for 61.5% of the variance of QoL. Psychological resilience and mental health status contributed to QoL only indirectly, through their associations with momentary mood. Collectively, these results highlight the importance of ecological momentary assessment of mental-health related factors such as mood to the prediction of QoL in young adults under stress. These findings may have broader implications for monitoring and improvement of well-being in young healthy populations as well as in clinical ones.
多种内部因素，如心理韧性和心理健康状况，已被证明对总体生活质量（QoL）有影响。然而，迄今为止，很少有研究探讨这些因素如何在压力情境下对青少年和青年的生活质量产生影响。在此，我们研究了这些因素以及生态瞬时情绪评估对年轻新兵在基础训练战斗（BCT）期间生活质量的影响。为此，我们从以色列国防军（IDF）一个混合性别单位的156名男女士兵中收集了数据。使用安装在参与者手机上的移动应用程序，参与者在基线时提供了关于他们心理健康状况和心理韧性的自我报告，以及两周后的生活质量报告。在为期两周的间隔期内，使用每日自我报告情绪量表（IMS - 12）进一步收集瞬时情绪报告。基于一个假设模型，使用结构方程模型（SEM）来检验研究变量之间的相互关系。我们发现，包含所有因素（性别、韧性、心理健康状况和瞬时情绪）的模型根据其拟合指数对数据拟合良好[χ(38) = 47.506, = 0.139, CFI = 0.979, NFI = 0.910, RMSEA = 0.040, TLI = 0.964]。然而，对生活质量的唯一直接影响因素是性别和瞬时情绪，它们共同解释了生活质量方差的61.5%。心理韧性和心理健康状况仅通过与瞬时情绪的关联对生活质量产生间接影响。总体而言，这些结果凸显了对与心理健康相关因素（如情绪）进行生态瞬时评估对预测压力下年轻人生活质量的重要性。这些发现可能对监测和改善年轻健康人群以及临床人群的幸福感具有更广泛的意义。
