Long-term evaluation of psychosocial impact and stuttering severity after intensive stuttering therapy.

Purpose: The purpose of this study was to assess the long-term stability of objective and subjective psychosocial improvements and fluency more than 10 years after participation in an intensive stuttering therapy camp.

Method: Ten former participants in intensive stuttering therapy (IST; mean age at time of intervention 14; 2 years) participated in this study. Outcomes of the IST at that time were assessed with the Stuttering Severity Instrument (SSI-3; Riley, 1994) and a questionnaire to measure the psychosocial impact of stuttering.
