虽然运动性抽搐和/或发声性抽搐是慢性抽动障碍（CTD）和抽动秽语综合征（TS）的特征，但老年人和成年人经常报告他们的抽搐之前有不愉快的感觉或“先兆冲动”。“虽然先兆冲动现象可能在CTD/TS的行为干预中发挥重要作用，但先兆冲动的标准化评估并不存在。目前对42名TS或CTD青少年的研究为一种新的、简短的自我报告量表提供了初步的心理测量数据，该量表旨在测量抽搐相关的先兆冲动。结果显示，抽搐先兆冲动量表（PUTS）在1周（r = 0.79，p <0.01）和2周（r = 0.86，p <0.01）时具有内部一致性（α = 0.81）和时间稳定性。PUTS评分也与耶鲁整体抽动严重程度量表（YGTSS; r = 0.31，p <0.05）和YGTSS数量（r = 0.35，p <0.05）、复杂性（r = 0.49，p <0.01）和干扰（r = 0.36，p <0.05）子量表测量的整体抽动严重程度相关。最后，对先兆冲动现象的精神病学相关性进行了检查，发现PUTS和儿童行为检查表（CBCL）焦虑/抑郁之间存在显著相关性（r = 0.33，p <0.05）和退缩（r = 0.38，p <0.05）分量表以及儿童耶鲁-布朗强迫量表（CYBOCS; r = 0.31，p <0.05）。然而，对数据的横断面检查显示，PUTS的心理测量特性对于10岁及以下的青少年是不可接受的。同样，YGTSS分量表，CBCL分量表，CYBOCS和PUTS之间的显着相关性没有出现在这个年轻的年龄组。这些研究结果的临床和理论意义进行了讨论。
Although motor tics and/or vocal tics are the defining features of chronic tic disorder (CTD) and Tourette syndrome (TS), older youths and adults often report their tics to be preceded by an unpleasant sensation or "premonitory urge." While premonitory urge phenomena may play an important role in behavioral interventions for CTD/TS, standardized assessments for premonitory urges do not exist. The current study of 42 youths with TS or CTD presents initial psychometric data for a new, brief self-report scale designed to measure tic-related premonitory urges. Results showed that the Premonitory Urge for Tics Scale (PUTS) was internally consistent (alpha = .81) and temporally stable at 1 (r = 0.79, p < .01) and 2 (r = 0.86, p < .01) weeks. PUTS scores were also correlated with overall tic severity as measured by the Yale Global Tic Severity Scale (YGTSS; r = 0.31, p < .05) and the YGTSS number (r = 0.35, p < .05), complexity (r = 0.49, p < .01), and interference (r = 0.36, p < .05) subscales. Finally, an examination of the psychiatric correlates of the premonitory urge phenomenon yielded significant correlations between the PUTS and the Child Behavior Checklist (CBCL) anxiety/depression (r = 0.33, p < .05), and withdrawal (r = 0.38, p < .05) subscales as well as the Children's Yale-Brown Obsessive Compulsive Scale (CYBOCS; r = 0.31, p < .05). However, a cross-sectional examination of the data showed that the psychometric properties of the PUTS were not acceptable for youths 10 years of age and younger. Likewise, significant correlations found between the YGTSS subscales, CBCL subscales, CYBOCS, and the PUTS did not emerge in this younger age group. The clinical and theoretical implications of these findings are discussed.
