Readiness for change, as assessed by the readiness and motivation interview (RMI), predicts a number of clinical outcome variables in eating disorders including enrollment in intensive treatment, symptom change, dropout, and relapse. Although clinically useful, the training and administration of the RMI is time consuming. The purpose of this research was to (a) develop a self-report, symptom-specific version of the RMI, the readiness and motivation questionnaire (RMQ), that can be used to assess readiness for change across all eating disorder diagnoses and (b) establish its psychometric properties. The RMQ provides stage of change, internality, and confidence scores for each of 4 eating disorder symptom domains (restriction, bingeing, and cognitive and compensatory behaviors). Individuals (N = 244) with current eating disorder diagnoses completed the RMQ and measures of convergent, discriminant, and criterion validity. Similar to the RMI scores, readiness scores on the RMQ differed according to symptom domain. Regarding criterion validity, RMQ scores were significantly associated with ratings of anticipated difficulty of recovery activities and completion of recovery activities. The RMQ contributed significant unique variance to anticipated difficulty of recovery activities, beyond those accounted for by the RMI and a questionnaire measure of global readiness. The RMQ is thus an acceptable alternative to the RMI, providing global and domain-specific readiness information when time or cost prohibits use of an interview.
改变准备度评估,采用准备和动机访谈(RMI),可以预测多种进食障碍的临床结果变量,包括参加强化治疗、症状改变、脱落和复发。尽管在临床上有用,但 RMI 的培训和管理既耗时又费力。本研究的目的是:(a)开发一种 RMI 的自我报告、症状特异性版本,即准备和动机问卷(RMQ),可用于评估所有进食障碍诊断的改变准备度;(b)建立其心理测量特性。RMQ 为 4 个进食障碍症状领域(限制、暴食、认知和补偿行为)的每个领域提供阶段、内在性和信心得分。当前患有进食障碍的个体(N=244)完成了 RMQ 和趋同、区分和标准有效性的测量。与 RMI 评分相似,RMQ 的准备度评分因症状领域而异。关于标准有效性,RMQ 评分与预期恢复活动的难度评分和完成恢复活动的评分显著相关。RMQ 对预期恢复活动的难度评分有显著的独特贡献,超出了 RMI 和全球准备度问卷测量所解释的部分。因此,RMQ 是 RMI 的一个可接受的替代品,在时间或成本不允许使用访谈时提供全球和特定领域的准备信息。
