Experimental Functional analysis (EFA) is considered the "gold standard" of behavioural assessment and its use is predictive of treatment success. However, EFA has a number of limitations including its lengthy nature, the high level of expertise required, and the reinforcement of challenging behaviour. This study aimed to further validate a novel interview-informed synthesised contingency analysis (IISCA).
An open-ended interview and brief direct observation informed an IISCA for a young boy with autism who engaged in challenging behaviour. Resulting data supported the hypothesis that the target behaviour was multiply controlled by escape from demands and access to tangible items. An intervention comprised of most-to-least prompting, escape extinction, differential reinforcement and a high-probability instruction sequence was evaluated using a reversal design.
This intervention reduced challenging behaviour to low levels and resulted in increased compliance.
Findings support the status of the IISCA as a valid, practical, and effective process for designing function-based interventions.
实验性功能分析（EFA）被视为行为评估的“金标准”，其应用可预测治疗效果。然而，EFA存在诸多局限性，包括耗时较长、所需专业知识水平较高以及强化挑战性行为等。本研究旨在进一步验证一种新型的基于访谈的综合权变分析（IISCA）。
通过开放式访谈和简短直接观察，为一名有挑战性行为的自闭症小男孩进行IISCA。所得数据支持了目标行为受逃避要求和获取有形物品多重控制的假设。采用反转设计对由从最多提示到最少提示、逃避消退、差别强化和高概率指令序列组成的干预措施进行了评估。
该干预措施将挑战性行为减少到低水平，并提高了依从性。
研究结果支持IISCA作为设计基于功能的干预措施的有效、实用且高效流程的地位。
