Positive behaviour support (PBS) is behaviour analysis applied in support of people with challenging behaviour. Questions have been raised as to PBS effectiveness, costs, and accessibility.
Outcome studies meeting specified criteria for PBS were selected for review. All told, 12 outcome studies encompassing 423 cases were included.
This review showed that PBS was effective with both severe and high-rate behaviour problems, was cost-effective, used a methodology that was easily trained and widely disseminated, and worked in institutional settings in which the most difficult problems are thought to be, as well as in the community.
The major implication of this review is that practitioners may be obligated to use PBS when faced with the need to develop a plan of support given the ethical principle of using the least restrictive method consistent with the right to effective treatment.
积极行为支持（PBS）是一种应用于支持具有挑战性行为的人的行为分析方法。人们对PBS的有效性、成本和可及性提出了疑问。
选择符合PBS特定标准的结果研究进行综述。总共纳入了12项涵盖423个案例的结果研究。
该综述表明，PBS对严重和高频行为问题均有效，具有成本效益，采用的方法易于培训且广泛传播，在被认为存在最困难问题的机构环境以及社区中均有效。
该综述的主要意义在于，鉴于使用与有效治疗权相一致的限制最少方法这一伦理原则，从业者在面临制定支持计划的需求时可能有义务使用PBS。
