Beliefs about the controllability of behaviour have been consistently shown to be important in understanding the responses of carers to the challenging behaviour of people with intellectual disabilities (IDs). This paper reports the reliability and validity of the controllability beliefs scale (CBS), a 15-item measure of beliefs regarding the controllability of challenging behaviour when used with carers of people with IDs.
Two hundred and sixty-four carers of people with IDs completed the CBS, 74 people also completed the modified attributional style questionnaire and the self-injury behavioural understanding questionnaire scale to determine concurrent and convergent validity and 34 people completed the scale twice within a 2- to 4-week period to determine test-retest reliability.
The scale has a two-factor structure and has adequate internal reliable. The scale is significantly correlated with the controllability, internality and stability items from the Modified Attributional Style Questionnaire, showed expected associations with behavioural and internal emotional understanding items from the self-injury behavioural understanding questionnaire. The scale has good test-retest reliability.
The data support use of the CBS in clinical practice and research to assess carers' beliefs regarding challenging behaviour of people with IDs.
行为可控性信念一直被证明在理解照顾者对智力障碍（ID）患者挑战性行为的反应方面非常重要。本文报告了可控性信念量表（CBS）的信度和效度，该量表是一个包含 15 个项目的测量工具，用于测量照顾者对 ID 患者挑战性行为的可控性信念。
264 名 ID 患者的照顾者完成了 CBS，74 名照顾者还完成了修改后的归因风格问卷和自我伤害行为理解问卷量表，以确定同时和收敛效度，34 名照顾者在 2 到 4 周的时间内两次完成量表，以确定测试-重测信度。
该量表具有双因素结构，具有足够的内部可靠性。该量表与修改后的归因风格问卷中的可控性、内在性和稳定性项目显著相关，与自我伤害行为理解问卷中的行为和内部情绪理解项目具有预期的关联。该量表具有良好的测试-重测信度。
数据支持在临床实践和研究中使用 CBS 来评估照顾者对 ID 患者挑战性行为的信念。
