Background & Objectives: The purpose of this study was to review trends and advancements in treatments for stuttering and to provide directions for future research on the treatment of stuttering.
Methods: Experimental research articles were selected based on the following criteria: (1) the characteristics of people who stutter (PWS) related to treatment or treatment affects; (2) articles published between 2000 and 2009 (within a 10 year span); and (3) publication in one of four major journals in the field of communication disorders: Korean Journal of Communication Disorders (KJCD), Korean Journal of Speech- Language, and Hearing Disorders (KJSLHD), Journal of Speech, Language, and Hearing Research (JSLHR), and Journal of Fluency Disorders (JFD). Independent and dependent variables were separately analyzed.
Results: A total of 77 articles that met all criteria were chosen. The results show that 29 articles (37.66%) investigated the efficacy of stuttering treatment, 24 articles (31.17%) compared the characteristics of PWS with people who do not stutter, and 24 articles (31.17%) studied the characteristics of PWS. In terms of participants, 50 articles (64.94%) included participants who were adolescents and/or adults, 14 articles (18.18%) included preschool children, and 6 articles (7.79%) included school-aged children. Articles based on the effects of treatment focused on behavioral components using treatment methods and longitudinally compared the changes between groups and/or within groups. The majority of characteristic articles also focused on behavioral components and cross-sectionally compared the characteristics between groups and/or within groups. The analyses of dependent variables demonstrated that articles on the effects of treatment and characteristics mostly measured or compared speech patterns, such as types and frequencies of disfluencies, naturalness of speech, and speaking rate. Perceptions of stuttering treatment, accessory behaviors, and emotional/personality characteristics were also studied.
Discussion & Conclusion: Overall trends show that there are more studies related to the characteristics of stuttering than the effects of stuttering treatment. Even though the history of research regarding the effects of stuttering intervention for children is relatively short, as compared to that of adults, recently, several treatment methods have been developed or updated for early childhood stuttering, and empirical studies have shown efforts to validate the treatment efficacy. For the adolescent and adults who stutter, several behavioral and/or cognitive treatment methods and devices are used to diminish stuttering. Suggestions from the perspective of evidence-based treatment are provided as future directions.
