Prevalence rates of challenging behaviour are high in children and adults with profound intellectual and multiple disabilities (PIMD). Moreover, many of these behaviours are observed daily. Direct support staff report that most challenging behaviour identified has little impact on the person with PIMD and attribute challenging behaviour in children and adults with PIMD mainly to a biomedical model. The purpose of this study was to evaluate whether an intervention (psycho-education) had any effect on direct support staff's assessment of challenging behaviour in terms of its severity and their biomedical causal explanations (attributions) for this behaviour.
A stepped wedge study design was used to evaluate the effects of a psycho-education intervention on the perceived severity and the attributions offered for challenging behaviour of people with PIMD by 198 direct support staff. We used questionnaires assessing the perceived severity of challenging behaviour and staff views of its causes. Data on the dependent variables were collected at four 1-month intervals.
The intervention was found to have an effect on the perceived severity of challenging behaviour identified in people with PIMD in the sense that staff generally scored challenging behaviour as more severe in its consequences after the intervention. However, this effect was very small. No significant effects were found in terms of reduction in the biomedical scale scores.
No evidence for the effectiveness of a psycho-educational approach on the assessment of challenging behaviour in terms of severity and the biomedical attributions for behaviour was found. More research is required to explore further the effects of more elaborate training using methods to enable direct support staff to reflect on the behaviour of people with PIMD and on their own behaviour.
重度智力和多重残疾(PIMD)儿童及成人中挑战性行为的发生率很高。此外,这些行为中有许多每天都会出现。直接支持人员报告称,所识别出的大多数挑战性行为对PIMD患者影响不大,并将PIMD儿童及成人的挑战性行为主要归因于生物医学模式。本研究的目的是评估一项干预措施(心理教育)是否会对直接支持人员在挑战性行为的严重程度评估及其对此行为的生物医学因果解释(归因)方面产生任何影响。
采用阶梯楔形研究设计,以评估心理教育干预对198名直接支持人员对PIMD患者挑战性行为的感知严重程度及归因的影响。我们使用问卷来评估挑战性行为的感知严重程度以及工作人员对其原因的看法。在四个1个月的间隔期收集了关于因变量的数据。
发现该干预措施对PIMD患者中所识别出的挑战性行为的感知严重程度有影响,即工作人员在干预后普遍将挑战性行为的后果评定为更严重。然而,这种影响非常小。在生物医学量表得分降低方面未发现显著影响。
未发现心理教育方法在挑战性行为严重程度评估及行为的生物医学归因方面有效的证据。需要开展更多研究,以进一步探索采用使直接支持人员能够反思PIMD患者行为及自身行为的方法进行更精细培训的效果。
