In patients with atopic dermatitis agreeableness and public self-consciousness have previously been shown to be significant predictors of induced scratching, while depression was significantly related to induced itch. This study aimed to replicate these findings. Itch and scratching were induced by videos of crawling insects or skin diseases. Induced itch was measured using a visual analogue scale. Scratching behavior was evaluated by two raters. Psychological variables were assessed using validated questionnaires. Induced scratching could be predicted significantly by agreeableness (corrected R2 = 15.5% or 38 % after exclusion of one outlier): Patients scoring low on agreeableness showed a higher increase in scratch movements than patients scoring high on this scale. No associations between induced scratching/itch and public self-consciousness/depression were found. One clinical implication that arises from this study could be to offer patients scoring low on agreeableness certain psychological interventions.
在特应性皮炎患者中，随和性和公众自我意识先前已被证明是诱发搔抓的重要预测因素，而抑郁与诱发瘙痒显著相关。本研究旨在重复这些发现。通过爬行昆虫或皮肤病的视频诱发瘙痒和搔抓。使用视觉模拟量表测量诱发瘙痒。由两名评估者评估搔抓行为。使用经过验证的问卷评估心理变量。随和性可显著预测诱发搔抓（排除一个异常值后校正R2 = 15.5%或38%）：在随和性量表上得分低的患者比得分高的患者搔抓动作增加得更多。未发现诱发搔抓/瘙痒与公众自我意识/抑郁之间存在关联。本研究产生的一个临床意义可能是为在随和性方面得分低的患者提供某些心理干预。
