This study assessed factors that predicted therapy outcome for children and adolescents who stuttered after attendance at an intensive therapy course. The factors examined were stuttering severity, lexical diversity measured by Type Token Ratio, and psychosocial impact of stuttering on the child's life.
Fifty-four children who stuttered (CWS) participated in the study. The hypotheses were: (1) CWS with high initial stuttering severity would be more likely to persist than those with low initial severity; (2) lexical diversity before treatment should be related to therapy outcome; (3) psychosocial factors would affect therapy outcome. The predictions were assessed by linear and logistic regression analyses.
Initial stuttering severity was the only significant predictor for stuttering severity after therapy. However, psychosocial impact correlated with improvement in fluency, and lexical diversity correlated with therapy outcome.
Only initial stuttering severity was a significant predictor of therapy outcome after an intensive therapy intervention. This is in agreement with the study of Howell and Davis (2011).
Readers will get an overview of the literature on risk factors that are considered to predict therapy outcomes for CWS. They will be able to (a) identify what variable represent potential risk factors, (b) describe the psychosocial impact of stuttering, (c) explain how lexical diversity is measured, and (d) describe different assessment instruments used to decide on the outcome of therapy.
本研究评估了口吃儿童和青少年参加强化治疗课程后治疗效果的预测因素。检查的因素包括口吃严重程度、词汇多样性（用类型令牌比衡量）以及口吃对孩子生活的心理社会影响。
54 名口吃儿童（CWS）参加了这项研究。假设是：（1）初始口吃严重程度高的 CWS 比初始严重程度低的 CWS 更有可能持续存在；（2）治疗前的词汇多样性应与治疗效果相关；（3）心理社会因素会影响治疗效果。通过线性和逻辑回归分析评估了预测。
初始口吃严重程度是治疗后口吃严重程度的唯一显著预测因素。然而，心理社会影响与流畅度的改善相关，词汇多样性与治疗效果相关。
只有初始口吃严重程度是强化治疗干预后治疗效果的显著预测因素。这与 Howell 和 Davis（2011）的研究一致。
读者将对被认为可以预测 CWS 治疗效果的风险因素的文献有一个概述。他们将能够（a）识别哪些变量代表潜在的风险因素，（b）描述口吃的心理社会影响，（c）解释词汇多样性是如何衡量的，以及（d）描述用于决定治疗效果的不同评估工具。
