This study examined the relationship of limit-setting interventions and six-month outcomes in assertive community treatment.
Case managers from 40 Veterans Affairs assertive community treatment teams at 40 different sites documented their use of 25 limit-setting activities with 1564 clients during the first six months of treatment. Five scales were constructed representing different types of limit-setting activities: withholding certain types of assistance until the client curtailed certain behaviors; behavioral contracting in which specific goals were identified and linked to reinforcers if the goals were achieved; invocation of external authorities, such as a probation officer; seeking a declaration of incompetence to manage funds or initiation of a request for a payee; and forced hospitalization through civil commitment. Structured interviews conducted at baseline and six months documented changes in clinical status and community adjustment. Multiple regression analysis was used to examine the relationship between limit-setting interventions and outcomes at both the level of the individual client and at the level of the team, adjusting for potentially confounding baseline client characteristics.
All five measures of specific limit-setting activities were associated with poorer outcomes on four to six of the eight outcome measures. The site-level comparison of outcomes showed more violent behavior at sites that made more extensive use of these interventions but also greater employment.
After the analysis controlled for potentially confounding factors, clients exposed to limit-setting interventions had poorer outcomes than others on many measures, suggesting that within the limits of a nonexperimental study, such interventions do not appear to prevent adverse outcomes.
本研究探讨了在积极社区治疗中设定界限干预措施与六个月治疗结果之间的关系。
来自40个不同地点的40个退伍军人事务积极社区治疗团队的个案管理员记录了他们在治疗的前六个月中对1564名客户使用25种设定界限活动的情况。构建了五个量表,代表不同类型的设定界限活动:在客户减少某些行为之前 withhold 某些类型的援助;行为契约,即确定具体目标并在目标实现时与强化物相联系;援引外部权威,如缓刑监督官;寻求无能力管理资金的声明或启动指定收款人请求;以及通过民事强制住院。在基线和六个月时进行的结构化访谈记录了临床状况和社区适应情况的变化。使用多元回归分析在个体客户层面和团队层面检验设定界限干预措施与结果之间的关系,并对潜在的混淆基线客户特征进行调整。
所有五项特定设定界限活动的测量指标都与八项结果测量指标中的四项至六项较差的结果相关。结果的地点层面比较显示,在更广泛使用这些干预措施的地点,暴力行为更多,但就业情况也更好。
在分析控制了潜在的混淆因素后,接受设定界限干预措施的客户在许多指标上的结果比其他客户差,这表明在非实验性研究的范围内,此类干预措施似乎无法预防不良结果。
