Is More Intensive Better? Client and Service Provider Outcomes for Intensive Versus Standard Therapy Schedules for Functional Voice Disorders

Abstract

Functional dysphonias are commonly associated with reduced treatment attendance leading to variable treatment outcomes. Preliminary research has proposed that intensive treatment may improve client adherence and outcomes; however, further research into the application of intensive models in functional dysphonia in comparison with standard intensity models is warranted. The present study evaluated the impact of intensive and standard treatments on functional, well-being, and service outcome measures in clients with functional dysphonia. Participants with a functional dysphonia were randomly allocated to one of two treatment groups: (1) intensive treatment (n=7) or (2) standard treatment (n=9). Participants completed the voice handicap index (VHI) and the Australian therapy outcome measures voice assessment (conducted by a blinded assessor) before and after treatment and 4weeks after treatment. Satisfaction questionnaires were completed after treatment and data pertaining to attendance and duration of intervention were collected throughout treatment. In addition to a vocal hygiene education session, all participants received a total of 8hours of treatment; intensive treatment consisted of four 1-hour treatment sessions per week over 2weeks, whereas the standard group received one 1-hour treatment session per week over 8weeks. High satisfaction and statistically significant improvements on the VHI ratings were found after treatment in the intensive group. Significantly greater attendance rates were found in the intensive group. Intensive treatment is a potentially viable service delivery option for functional dysphonia and warrants further larger scale investigation.
