Evaluation of an integrated fluency and Acceptance and Commitment Therapy intervention for adolescents and adults who...

Childhood-onset stuttering is a neurodevelopmental disorder that may cause pervasive negative consequences for adults who stutter. In addition to significant challenges in personal, social, and emotional domains, stuttering has been shown to impose an economic burden on adults who stutter. Intervention for adults who stutter has historically addressed speech fluency more so than the covert psychosocial aspects of the disorder. There is an identified clinical need for holistic, efficacious, and cost-effective stuttering interventions that meet consumer needs. The purpose of the present study is to evaluate a novel, integrated intervention that combined traditional fluency techniques with Acceptance and Commitment Therapy, from the perspective of the adults who stutter who participated in the intervention.

Twenty-eight adults who stutter completed the intervention program. Participants were invited to complete an online post-program written survey (including qualitative comments) and a semi-structured interview to explore their evaluations of the program with respect to its authenticity, acceptability, and social validity.

Participants perceived positive psychosocial changes as a result of the program, and were satisfied with the program overall. Qualitative thematic analyses of the written survey comments and the semi-structured interviews identified two major themes: factors specific to the intervention and factors specific to the therapeutic process. Several important sub-themes were also identified.

Findings support the authenticity, acceptability, and social validity of an integrated fluency and psychosocial intervention for stuttering. Findings also highlight the need for consideration of the consumer voice in the management of stuttering disorders, in keeping with person-centred care.
