PURPOSE To examine the relationship of character strengths and quality of life (QOL) in persons with multiple sclerosis (MS). Specifically, this study examined the relationship of the 24 character strengths in Peterson and Seligman's model with QOL and three negative effects of MS (disability, fatigue, and depression). It also investigated whether the three negative effects of MS mediate the relationship of each of the character strengths and QOL. METHODS Six hundred and twenty-four individuals with MS completed an online survey measuring character strengths, QOL, as measured by the Leeds Multiple Sclerosis Quality of Life Scale, disability, fatigue, and depression. SPSS was used to complete the correlational analysis, and Hayes' PROCESS macro for SPSS was used to conduct the mediation analyses. RESULTS The strengths endorsed most frequently by the participants were honesty, kindness, and fairness. The least-endorsed strengths were self-regulation, zest, and spirituality. The strengths with the strongest association with QOL were zest, hope, and gratitude. Disability was not found to mediate any of the relationships between character strengths and QOL. Many of the character strengths were associated with QOL both directly and indirectly through fatigue and depression. CONCLUSIONS Many of the character strengths in the Peterson and Seligman model enhance QOL in persons with MS, both directly and through their influence on negative effects of MS. The results provide support for the development of character strengths interventions to impact QOL, both directly and indirectly through improvements to MS-related symptoms such as fatigue and depression.

多发性硬化症患者的人格特质与生活质量的关系分析。

目的探讨多发性硬化症（MS）患者的人格优势与生活质量（QOL）的关系。具体而言，本研究考察了Peterson和Seligman模型中24个字符强度与QOL和MS的三个负面影响（残疾，疲劳和抑郁）之间的关系。它还调查了MS的三个负面影响是否介导了每个字符强度和QOL的关系。方法624名MS患者完成了一项在线调查，该调查通过利兹多发性硬化症生活质量量表，残疾，疲劳和抑郁来测量性格优势QOL。SPSS用于完成相关分析，而Hayes的SPSS宏用于进行中介分析。结果参与者最常认可的优势是诚实，善良和公平。最不被认可的优势是自我调节，热情和灵性。与QOL联系最紧密的力量是热情，希望和感激之情。没有发现残疾能够介导角色能力和QOL之间的任何关系。许多角色的优势都通过疲劳和沮丧直接或间接地与QOL相关。结论Peterson和Seligman模型中的许多角色优势直接或通过其对MS负面影响的影响而增强了MS患者的QOL。结果为发展影响QOL的性格优势干预措施提供了支持，
