The Skin Picking Impact Scale (SPIS) is a self-report instrument developed to assess the psychosocial consequences of repetitive skin picking. An initial 28-item scale was administered to 31 individuals with severe self-injurious skin picking and 78 individuals with non-self-injurious skin picking. Item difficulty levels and part-whole correlations resulted in a 10-item scale with good internal consistency. SPIS scores for those with self-injurious skin picking were significantly higher than for those with non-self-injurious skin picking. SPIS scores for those with self-injurious skin picking correlated with duration of daily picking, satisfaction during picking, and shame subsequent to picking, as well as Beck Depression Inventory and Beck Anxiety Inventory scores. Sensitivity and specificity analyses indicate that a scale cutoff score of 7 optimally discriminates individuals with self-injurious skin picking from those with non-self-injurious skin picking.
皮肤搔抓影响量表（SPIS）是一种为评估重复性皮肤搔抓的心理社会后果而开发的自我报告工具。最初的28项量表应用于31名有严重自伤性皮肤搔抓行为的个体和78名无自伤性皮肤搔抓行为的个体。根据项目难度水平和整体相关性，最终形成了一个10项量表，具有良好的内部一致性。有自伤性皮肤搔抓行为个体的SPIS得分显著高于无自伤性皮肤搔抓行为个体。有自伤性皮肤搔抓行为个体的SPIS得分与每日搔抓时长、搔抓时的满足感、搔抓后的羞耻感以及贝克抑郁量表和贝克焦虑量表得分相关。敏感性和特异性分析表明，量表截止分数为7时能最佳地区分有自伤性皮肤搔抓行为的个体和无自伤性皮肤搔抓行为的个体。
