ABSTRACT

The aim of this study was to assess the validity of a 14-item mental health self-efficacy scale developed to assess the effectiveness of the Road to Mental Readiness (R2MR) – a program aimed at improving the well-being and mental health of Canadian Armed Forces (CAF) personnel. The validity of the scale was assessed through an analysis of data collected as part of a pilot study and a larger group randomized control trial (GRCT) on the effectiveness of R2MR administered to CAF noncommissioned member recruits during basic training. Using data collected for the pilot study (N = 276), an initial review of items indicated a need to eliminate two redundant items and two items that were weakly correlated with other scale items. A parallel analysis and exploratory factor analysis (EFA) conducted on the resulting 10-item scale pointed to a one-factor model with all items loading satisfactorily. Using data from the GRCT (N = 1962), a confirmatory factor analysis (CFA) was conducted to further assess the revised scale. This CFA suggested good model fit (Root Mean Square Error of Approximation of .07 and Standardized Root Mean Square Residual of .06). The revised scale had an alpha of .88, was very strongly correlated with the full scale (r = .97, p < .001), and significantly predicted perceived control and self-efficacy regarding accessing mental health care and intention to access care.

摘要

这项研究的目的是评估开发的14个项目的心理健康自我效能感量表的有效性，该量表旨在评估“心理准备之路”（R2MR）的有效性–该计划旨在改善加拿大的福祉和心理健康武装部队（CAF）人员。该量表的有效性是通过对作为基础研究过程中向CAF士官招募的R2MR的有效性进行的一项试验研究和一项更大的小组随机对照试验（GRCT）进行分析而评估的，从而评估了该量表的有效性。使用为初步研究收集的数据（N =276），对项目的初步审查表明，有必要消除两个多余的项目以及与其他规模项目之间相关性较弱的两个项目。在所得的10个项目的规模上进行的并行分析和探索性因素分析（EFA）指向了一个单因素模型，所有项目均令人满意地加载。利用来自GRCT的数据（N = 1962），进行了验证性因子分析（CFA）以进一步评估修订后的量表。此CFA建议模型拟合良好（近似值的均方根误差为.07，标准均方根残差为.06）。修订后的量表的alpha为0.88，与满刻度高度相关（r = .97，p <.001），并显着预测了在获得心理健康护理和意图获得护理方面的感知控制和自我效能。
