ABSTRACT

Background

Intensive Comprehensive Aphasia Programs (ICAPs) implement evidence-based, holistic therapies in a short-duration cohort model. ICAPs are growing in popularity, yet there are still relatively few programs, partially due to the high cost of running an ICAP. ICAPs implemented by graduate student clinicians can reduce the overall cost of an ICAP, but Phase I efficacy data for cognitive-linguistic outcomes for an ICAP carried out by graduate students has yet to be reported.

Aims

To investigate the impact of a graduate student-run ICAP on measures of cognitive-linguistic change, and to identify relationships between individual and treatment variables and cognitive-linguistic function across pre- and post-ICAP administration.

Methods & Procedures

Fifty-three stroke survivors with chronic aphasia (33 males, 20 females; 32 first-time participants and 21 repeat participants; mean age = 65 years; mean time post-onset = 34 months) participated in an ICAP implemented by graduate students across eight cohorts. Cognitive-linguistic outcome measures included: Western Aphasia Battery, Revised (WAB-R); Boston Naming Test, Second Edition (BNT-2); and Raven’s Coloured Progressive Matrices (RCPM). Paired samples t-tests were used to compare pre- and post-ICAP performance for each measure, and Pearson’s r correlation coefficients were used to evaluate relationships between measures, as well as individual and treatment variables.

Outcomes & Results

Statistically significant change was observed on all three measures post-treatment, with small to no effect size. Participants who had completed a previous ICAP showed greater change on the WAB-R and RCPM, but no other individual or treatment variables significantly predicted change on outcome measures.

Conclusions

Results provide Phase I, proof-of-concept evidence of positive cognitive-linguistic change in stroke survivors with aphasia following ICAP participation. An ICAP implemented by graduate student clinicians produced significant improvements for persons with chronic aphasia.

由研究生临床医生实施的强化综合性失语症项目的认知语言结果

摘要

背景

强化综合失语计划 (ICAP) 在短期队列模型中实施基于证据的整体治疗。ICAP 越来越受欢迎，但程序仍然相对较少，部分原因是运行 ICAP 的成本很高。由研究生临床医生实施的 ICAP 可以降低 ICAP 的总体成本，但尚未报告由研究生实施的 ICAP 认知语言结果的 I 期疗效数据。

目标

调查研究生运行的 ICAP 对认知语言变化测量的影响，并确定个体和治疗变量之间的关系以及 ICAP 给药前后的认知语言功能。

方法和程序

53 名患有慢性失语症的中风幸存者（33 名男性，20 名女性；32 名首次参与者和 21 名重复参与者；平均年龄 = 65 岁；平均发病后时间 = 34 个月）参加了由 8 名研究生实施的 ICAP同伙。认知语言结果测量包括：西方失语电池，修订版(WAB-R)；波士顿命名测试，第二版(BNT-2)；和Raven 的彩色渐进矩阵(RCPM)。配对样本t检验用于比较每个测量的前后 ICAP 性能，并且使用 Pearson 的r相关系数来评估测量之间的关系，以及个体和治疗变量之间的关系。

结果和结果

在治疗后的所有三个测量中都观察到了统计学上的显着变化，影响大小很小甚至没有。完成之前 ICAP 的参与者在 WAB-R 和 RCPM 上表现出更大的变化，但没有其他个人或治疗变量显着预测结果测量的变化。

结论

结果为 ICAP 参与后患有失语症的中风幸存者提供了第一阶段的概念验证证据。由研究生临床医生实施的 ICAP 对慢性失语症患者产生了显着改善。
