Abstract
This experiment represents a preliminary stage of inquiry in a series of planned studies. Adult females with nodules participated as paid subjects. Some subjects received confidential voice therapy, some received resonant voice therapy, and some received no therapy (control condition) over an approximately two-week period. Pre- and post-measures provided some evidence of a benefit from therapy. Baseline measures were then repeated two weeks after therapy was terminated, for therapy subjects. The final results indicated that compliance scores (which reflected the degree to which subjects appeared to use the therapy technique outside the clinic) were relevant for predicting the likelihood of benefiting from therapy. However, the specific type of therapy that was administered was not. The primary importance of these findings is that they point to a need to assess compliance factors in future efficacy studies. The findings also emphasize the critical role of compliance in clinical voice practice, in general.
