The role of patient perceptions and hyperfunctional voice disorders in predicting voice therapy attendance.

OBJECTIVES/HYPOTHESIS: Attendance is essential to voice therapy's effectiveness in the treatment of voice and laryngeal disorders. With such high rates of drop-out and non-attendance, it is important to understand the factors that influence this behavior. This study sought to identify potential predictors of attendance to voice therapy at an interdisciplinary voice clinic.

STUDY

DESIGN

Single-institution retrospective cohort study.

METHODS

In this retrospective cohort study, patients evaluated at an interdisciplinary voice clinic who received a referral for voice therapy were identified. Age, gender, voice-related diagnoses, Voice Handicap Index-10 scores, Reflux Symptom Index scores, and measures of patient perceptions (self-rated severity, importance of voice in one's life, and "feelings about voice therapy") were recorded to evaluate associations with attendance to at least one therapy session. Standard statistical analysis and logistic regressions were performed.

RESULTS

Of 168 subjects included, 111 (66.1 %) attended at least one session of voice therapy. Patients diagnosed with primary hyperfunctional voice disorders had a significantly higher attendance rate than other groups. Attenders had higher self-ratings of severity and more positive "feelings about voice therapy" compared to non-attenders. Regression models found three significant predictors of therapy attendance: primary diagnosis of hyperfunctional voice disorder, self-rated severity, and "feelings about voice therapy."

CONCLUSION

In this cohort, patients with more positive feelings about voice therapy, higher self-rated severity, and a diagnosis of primary hyperfunctional voice disorder were more likely to attend voice therapy.
