Psoriasis exerts a profound negative impact on health-related quality of life (QoL). Although the severity of psoriasis is one potential variable that contributes to decreased QoL, previous studies have shown only weak or no association between measures of psoriasis severity and QoL. We hypothesized that this relationship is moderated by temperament factors.
We aimed to verify whether the relationship between disease severity and QoL is moderated by a constellation of temperament traits (i.e., temperament risk factors) and whether this moderation takes place via cognitive-appraisal and coping processes.
One hundred fifty patients with psoriasis vulgaris participated in the study. Psoriasis severity was assessed by a standardized measure, the Psoriasis Area and Severity Index (PASI), and the patients also completed a battery of psychological questionnaires assessing QoL, temperament, disease-related cognitive appraisals, and coping strategies.
A specific constellation of temperament traits was found to moderate the strength of the association between the PASI and QoL. This constellation of temperament traits was associated with certain disease-related cognitive appraisals (i.e., threat, obstacle/loss, harm, profit, value) and emotion-focused coping strategies (i.e., self-blame, avoidance, resignation, seeking social support, and seeking information).
The constellation of temperament traits is a crucial individual variable that strongly moderates the negative impact of psoriasis severity on QoL, potentially through the activation of non-adaptive cognitive appraisals and coping strategies in susceptible individuals.
银屑病对健康相关生活质量（QoL）产生深远的负面影响。尽管银屑病的严重程度是导致生活质量下降的一个潜在变量，但先前的研究表明，银屑病严重程度的衡量指标与生活质量之间的关联仅为微弱或不存在关联。我们假设这种关系受到气质因素的调节。
我们旨在验证疾病严重程度与生活质量之间的关系是否受到一系列气质特征（即气质风险因素）的调节，以及这种调节是否通过认知评估和应对过程发生。
150例寻常型银屑病患者参与了该研究。通过标准化测量银屑病面积和严重程度指数（PASI）评估银屑病严重程度，患者还完成了一系列心理问卷，评估生活质量、气质、疾病相关认知评估和应对策略。
发现特定的气质特征组合调节了PASI与生活质量之间关联的强度。这种气质特征组合与某些疾病相关的认知评估（即威胁、障碍/损失、伤害、收益、价值）和以情绪为中心的应对策略（即自责、回避、顺从、寻求社会支持和寻求信息）相关。
气质特征组合是一个关键的个体变量，它强烈调节银屑病严重程度对生活质量的负面影响，可能是通过激活易感个体的非适应性认知评估和应对策略来实现的。
