背景:简短的问卷可以全面捕获不同被调查者的关键限制和重复行为(RRB),从而有可能支持自闭症诊断服务。我们测试了20项重复行为问卷-3(RBQ-3)的心理测量特性,包括自我报告和举报人报告版本的问卷,可在整个生命周期中使用。
方法:在研究1中,成年人参考了专门的成人自闭症诊断服务(N=110)完成了RBQ-3自我报告版本,一位亲戚或长期朋友完成了RBQ-3线人报告版本。作为诊断过程的一部分,临床医生与相同的成年人完成了社会和沟通障碍诊断访谈(DISCO-缩写)的缩写版本。对于一半的评估,临床医生对RBQ-3评分视而不见.我们测试了内部一致性,RBQ-3的交叉信息信度和收敛效度。在研究2中,一项针对自闭症(N=151)和非自闭症(N=151)成年人的在线随访研究,我们进一步测试了RBQ-3自我报告版本的内部一致性.我们还测试了该样本中的组差异和反应模式。
结果:研究1显示,RBQ-3的自我报告版本和线人报告版本(总分,α=0.90,ω=0.90,子尺度,α=0.76-0.89,ω=0.77-0.88)。研究1还显示了交叉信息的可靠性,因为RBQ-3自我报告得分与总分(rs=0.71)和子量表(rs=0.69-0.72)的RBQ-3信息报告得分显着相关。RBQ-3的自我和信息版本均具有收敛效度,与DISCO缩写的RRB域得分显着相关(rs=0.45-0.54)。此外,RBQ-3分数与DISCO-社交交流领域的缩写分数的关联显着较弱,证明了不同的有效性。重要的是,即使临床医生对RBQ-3项目视而不见,也发现了这些有效性模式.在研究2中,对于自闭症和非自闭症群体,总分(α=0.82-0.89,ω=0.81-0.81)和分量表(α=0.68-0.85,ω=0.69-0.85)存在内部一致性.发现组间存在组间差异。
结论:由于自闭症专科诊断服务的特点和范围,需要进一步测试,以包括年龄(包括儿童)和智力的代表性样本,和那些非自闭症的诊断结果。
结论:RBQ-3是可在整个生命周期中使用的RRB问卷。当前的研究对没有智力障碍的自闭症成年人测试了其心理测量特性,并支持其在临床诊断和研究环境中的实用性。
Brief questionnaires that comprehensively capture key restricted and repetitive behaviours (RRBs) across different informants have potential to support autism diagnostic services. We tested the psychometric properties of the 20-item Repetitive Behaviours Questionnaire-3 (RBQ-3), a questionnaire that includes self-report and informant-report versions enabling use across the lifespan.
In Study 1, adults referred to a specialised adult autism diagnostic service (N = 110) completed the RBQ-3 self-report version, and a relative or long-term friend completed the RBQ-3 informant-report version. Clinicians completed the abbreviated version of the Diagnostic Interview for Social and Communication Disorders (DISCO-Abbreviated) with the same adults as part of the diagnostic process. For half of the assessments, clinicians were blind to the RBQ-3 ratings. We tested internal consistency, cross-informant reliability and convergent validity of the RBQ-3. In Study 2, a follow-up online study with autistic (N = 151) and non-autistic (N = 151) adults, we further tested internal consistency of the RBQ-3 self-report version. We also tested group differences and response patterns in this sample.
Study 1 showed good to excellent internal consistency for both self- and informant-report versions of the RBQ-3 (total score, α = 0.90, ω = 0.90, subscales, α = 0.76-0.89, ω = 0.77-0.88). Study 1 also showed cross-informant reliability as the RBQ-3 self-report scores significantly correlated with RBQ-3 informant-report scores for the total score (rs = 0.71) and subscales (rs= 0.69-0.72). Convergent validity was found for both self and informant versions of the RBQ-3, which significantly correlated with DISCO-Abbreviated RRB domain scores (rs = 0.45-0.54). Moreover, the RBQ-3 scores showed significantly weaker association with DISCO -Abbreviated scores for the Social Communication domain, demonstrating divergent validity. Importantly, these patterns of validity were found even when clinicians were blind to RBQ-3 items. In Study 2, for both autistic and non-autistic groups, internal consistency was found for the total score (α = 0.82-0.89, ω = 0.81-0.81) and for subscales (α = 0.68-0.85, ω = 0.69-0.85). A group difference was found between groups.
Due to the characteristics and scope of the specialist autism diagnostic service, further testing is needed to include representative samples of age (including children) and intellectual ability, and those with a non-autistic diagnostic outcome.
The RBQ-3 is a questionnaire of RRBs that can be used across the lifespan. The current study tested its psychometric properties with autistic adults without intellectual disability and supported its utility for both clinical diagnostic and research settings.
