Mild traumatic brain injury (MTBI) is a stressful life event that may impact various dimensions of life. Challenges to daily activities after MTBI may produce significant effects on quality of life (QOL).
The purposes of this cross-sectional descriptive study were to (a) explore QOL after experiencing MTBI, (b) determine the extent of social supports, and (c) identify factors that are associated with QOL in post-MTBI patients.
A descriptive research method was used. Potential subjects were interviewed by telephone after they signed the consent forms.
The average score of total social support was 73, the average availability subscale score was 40, and the average satisfaction subscale score was 33. The average score of total QOL was 24, the average health and functioning domain score was 22, the average psychological and spiritual domain score was 25, the average social and economic domain score was 25, and the average family domain score was 27. QOL was then regressed simultaneously on all factors after adjustment of the outliers. The model was supported (adjusted R = .246, F = 4.160, p < .001). The contribution of all the stimuli explained 24.6% of the variance in QOL (p < .0125). Social support was the most significant variable affecting the variance in QOL (the unstandardized regression coefficient = 1.105, the standardized regression coefficient = 0.414, t = 5.041, p < .001).
This study identified social support as the most powerful predictor for QOL. Several measures used in this study were reliable and may be used within the Thai cultural context. Further study to better understand why a small but clinically important percentage of subjects experience ongoing disability after MTBI is needed.
轻度创伤性脑损伤（MTBI）是一种可能影响生活各个方面的应激性生活事件。MTBI后日常活动面临的挑战可能会对生活质量（QOL）产生重大影响。
本横断面描述性研究的目的是：（a）探讨经历MTBI后的生活质量；（b）确定社会支持的程度；（c）识别与MTBI后患者生活质量相关的因素。
采用描述性研究方法。潜在受试者签署同意书后通过电话进行访谈。
社会支持总分平均分为73分，可获得性分量表平均分为40分，满意度分量表平均分为33分。生活质量总分平均分为24分，健康与功能领域平均分为22分，心理与精神领域平均分为25分，社会与经济领域平均分为25分，家庭领域平均分为27分。在剔除异常值后，对所有因素同时进行生活质量回归分析。该模型得到支持（调整后R = 0.246，F = 4.160，p < 0.001）。所有刺激因素的贡献解释了生活质量方差的24.6%（p < 0.0125）。社会支持是影响生活质量方差的最显著变量（非标准化回归系数 = 1.105，标准化回归系数 = 0.414，t = 5.041，p < 0.001）。
本研究确定社会支持是生活质量最有力的预测因素。本研究中使用的几种测量方法可靠，可在泰国文化背景下使用。需要进一步研究以更好地理解为什么一小部分但具有临床重要性的受试者在MTBI后会持续存在残疾。
