The aim of this study was to determine if learned helplessness, self-efficacy, and cognitive distortions would predict depression in a sample of 80 individuals with multiple sclerosis (MS) and 80 individuals with a spinal cord injury (SCI). As MS and SCI usually present with disparate disease courses and etiologies, a secondary objective was to determine if individuals with MS would exhibit greater levels of helplessness, cognitive distortions, and depression and lower levels of self-efficacy than those with SCI. Results indicated that helplessness and self-efficacy significantly predicted depression for both the MS and SCI groups after controlling for confounding variables. Cognitive distortions had no independent effect, indicating that cognitive distortions may have caused feelings of helplessness and low self-efficacy and, in this way, had indirect effects on depression. The MS group exhibited significantly greater levels of depression and helplessness and significantly lower levels of self-efficacy than the SCI group. It was hypothesized that it may have been the combination of an unpredictable course of disease activity and the possibility of being affected by MS in many different ways that produced greater feelings of depression, helplessness, and low self-efficacy in the MS group.
本研究的目的是确定习得性无助、自我效能感和认知扭曲是否能预测80名多发性硬化症(MS)患者和80名脊髓损伤(SCI)患者样本中的抑郁情况。由于MS和SCI通常具有不同的病程和病因,第二个目标是确定MS患者是否比SCI患者表现出更高水平的无助感、认知扭曲和抑郁,以及更低水平的自我效能感。结果表明,在控制混杂变量后,无助感和自我效能感对MS组和SCI组的抑郁均有显著预测作用。认知扭曲没有独立影响,这表明认知扭曲可能导致了无助感和低自我效能感,进而对抑郁产生间接影响。MS组比SCI组表现出显著更高水平的抑郁和无助感,以及显著更低水平的自我效能感。据推测,可能是疾病活动过程不可预测以及MS以多种不同方式影响个体的可能性相结合,导致MS组产生了更强烈的抑郁、无助和低自我效能感。
