The importance of psychosocial factors on the etiology and fluctuating disease activity of psoriasis has been discussed in recent years. The present experiment investigated whether psoriatics in an anger-inducing situation show less aggressive verbal behaviour than average person. Twenty-six psoriatics and 26 matched healthy controls were randomly assigned to either an anger-inducing or a non-anger-inducing social situation. The experimental conditions were arranged so that the persons were confronted with either negative, derogatory, or positive, favorable feedback on eight characteristics (intelligence, appearance, maturity, tolerance, honesty, friendliness, humor, and helpfulness). Standardized feedback was given by a confederate of the experimenter. Immediately after the feedback was received by the subjects the photo hand test (PHT) was applied. The PHT is an item-analyzed, validated projective test for aggression. Two independent raters categorized the subjects' responses into six mutually exclusive categories, including a category for responses with aggressive content. 2 x 2 analysis of variance (psoriatics vs controls; anger-induced vs non-anger induced) were calculated for the aggressive responses and the acting-out score (AOS). The results showed a significant interaction, suggesting that psoriatics did indeed exhibit fewer verbal aggression responses under anger-inducing circumstances than the controls.
近年来，心理社会因素对银屑病病因及病情波动的重要性已被广泛讨论。本实验旨在研究处于愤怒诱发情境中的银屑病患者是否比普通人表现出更少的攻击性言语行为。26名银屑病患者和26名匹配的健康对照者被随机分配到愤怒诱发或非愤怒诱发的社会情境中。实验条件设定为让受试者面对关于八个特征（智力、外貌、成熟度、宽容度、诚实度、友善度、幽默感和乐于助人程度）的负面、贬损性或正面、赞许性反馈。由实验者的一名助手提供标准化反馈。受试者收到反馈后，立即进行照片手部测试（PHT）。PHT是一种经过项目分析和验证的攻击性投射测试。两名独立评分者将受试者的反应分为六个相互排斥的类别，包括具有攻击性内容的反应类别。对攻击性反应和外显行为得分（AOS）进行2×2方差分析（银屑病患者与对照组；愤怒诱发组与非愤怒诱发组）。结果显示存在显著交互作用，表明银屑病患者在愤怒诱发情境下确实比对照组表现出更少的言语攻击反应。
