Personality traits influence health-related quality of life (HRQoL) in Parkinson's disease (PD). Further, an individual's personality traits can influence the strategies they use to cope with a particular stressful situation. However, in PD, the interplay between personality traits, choice of coping strategy, and their subsequent effect on HRQoL remains unclear.
The objective of this study was to examine whether personality (neuroticism and extraversion) indirectly affects HRQoL through the use of specific psychological coping strategies.
One hundred and forty-six patients with PD completed questionnaires on personality (Big Five Aspects Scale; BFAS), coping (Ways of Coping Questionnaire; WCQ), and mood-specific (Depression, Anxiety and Stress Scale; DASS-21) and disease-specific HRQoL (Parkinson's Disease Questionnaire; PDQ-39).
After controlling for gender, age at diagnosis, and age at testing, the emotion-focused coping strategy of escape-avoidance was significantly correlated with neuroticism and certain aspects of HRQoL (cognitive impairment and social support). This suggests that neurotic personality traits may negatively impact on some aspects of HRQoL due to an increased use of escape-avoidance coping strategies. By contrast, planned problem-solving and escape-avoidance coping strategies were both significantly linked to extraversion and interpersonal and mood-related domains of HRQoL. This suggests that extraversion may positively impact on some aspects of HRQoL due to patients adopting greater planned, problem-solving coping strategies, and using fewer escape-avoidance coping mechanisms.
Psychological interventions aimed at targeting maladaptive coping strategies, such as the use of escape-avoidance coping, may be effective in minimising the negative impact of neuroticism on HRQoL in PD.
人格特质会影响帕金森病（PD）患者的健康相关生活质量（HRQoL）。此外，个体的人格特质会影响他们应对特定压力情况的策略。然而，在 PD 中，人格特质、应对策略的选择及其对 HRQoL 的后续影响之间的相互作用尚不清楚。
本研究旨在探讨人格特质（神经质和外向性）是否通过特定的心理应对策略间接影响 HRQoL。
146 名 PD 患者完成了人格（大五人格量表；BFAS）、应对（应对方式问卷；WCQ）、情绪特异性（抑郁、焦虑和压力量表；DASS-21）和疾病特异性 HRQoL（帕金森病问卷；PDQ-39）的问卷。
在控制性别、诊断时年龄和测试时年龄后，逃避应对策略与神经质和某些 HRQoL 方面（认知障碍和社会支持）显著相关。这表明神经质人格特质可能由于逃避应对策略的增加而对某些 HRQoL 方面产生负面影响。相比之下，计划解决问题和逃避应对策略均与外向性以及人际关系和情绪相关的 HRQoL 领域显著相关。这表明外向性可能由于患者采用更多的计划性、解决问题的应对策略以及较少使用逃避应对机制，对某些 HRQoL 方面产生积极影响。
针对逃避应对等不良应对策略的心理干预措施可能有助于减轻神经质对 PD 患者 HRQoL 的负面影响。
