The Motivation Assessment Scale is an aid for hypothesis-driven functional analysis. This study presents its Spanish cross-cultural validation while examining psychometric attributes not yet explored. The study sample comprised 80 primary caregivers of children with autism. Acceptability, scaling assumptions, internal consistency, factor structure, inter-assessor reliability and agreement, and known-group validity analyses were performed. Scaling assumptions, internal consistency (Cronbach alpha of 0.75) and factor structure were satisfactory other than for the Escape domain which demonstrated low internal consistency (0.65), inadequate scaling assumptions (multitrait analysis, 50% success rate) and did not constitute a separate factor. Caregivers' agreement for the primary function reached 73.9% and known group-validity hypotheses across behavior topographies were partially met. The clinical appropriateness of the scale is discussed.
动机评估量表是一种有助于假设驱动的功能分析的工具。本研究介绍了其西班牙语跨文化验证,同时检验了尚未探索的心理测量属性。研究样本包括 80 名自闭症儿童的主要照顾者。进行了可接受性、刻度假设、内部一致性、因子结构、评估者间信度和一致性以及已知组有效性分析。除了逃避维度外,刻度假设、内部一致性(Cronbach alpha 为 0.75)和因子结构均令人满意,逃避维度的内部一致性较低(0.65),刻度假设不充分(多特质分析,成功率为 50%),且不能构成单独的因子。主要功能的照顾者一致性达到 73.9%,行为形态的已知组有效性假设得到部分满足。讨论了该量表的临床适宜性。
