ABSTRACT

Primary Objective

This study examined the mediating role of perceived social support and mastery on quality of life (QOL) among adults with brain injury.

Research Design

An a priori structural model hypothesizing the relationships among symptom severity, mastery, social support, and QOL variables were tested.

Methods and Procedures

Individuals with brain injury across the United States participated in an online survey (N = 183). Structural equation modeling (SEM) was used to examine the model fit.

Main Outcomes and Results

The model fit the data well (χ² ₍₁₅₎ = 13.68). The Normed Bentler-Bonnet Fit Index (NFI) was.97; Goodness-of-Fit Statistic (GFI) was .98; Adjusted-Goodness-of-Fit (AGFI) was.96; and the Comparative Fit Index (CFI) was 1.00. The direct effects supported all expected relationships among the study variables. Social support and mastery fully mediated the relationship between symptom severity and QOL. Mastery partially mediated the relationship between social support and QOL.

Conclusions

These findings underscore the importance of incorporating psychosocial factors into interventions, with attention on increasing levels of perceived social support and mastery skills to foster greater QOL.

脑损伤患者生活质量的调解人

摘要

主要目标

这项研究检查了社交支持和掌握对脑损伤成人生活质量（QOL）的中介作用。

研究设计

先验结构模型假设症状严重程度，精通，社会支持和生活质量变量之间的关系进行了测试。

方法与程序

全美有脑损伤的人参加了在线调查（N = 183）。使用结构方程建模（SEM）来检查模型拟合。

主要结果和结果

该模型拟合数据阱（χ ² _（15）  = 13.68）。Normed Bentler-Bonnet适应指数（NFI）为97；拟合优度统计（GFI）为0.98；调整后的拟合优度（AGFI）为96；比较拟合指数（CFI）为1.00。直接影响支持了研究变量之间的所有预期关系。社会支持和精通完全调节了症状严重程度与生活质量之间的关系。精通部分调解了社会支持与生活质量之间的关系。

结论

这些发现强调了将社会心理因素纳入干预措施的重要性，并着重于提高人们感知的社会支持和掌握技能的水平，以培养更高的生活质量。
