ObjectivesThe origin and development of dysphonia, particularly behavioral dysphonia, is associated with several risk factors. Here, we verified the effectiveness of group therapy in reducing the risk factors, and established the association between risk factors and sex, age, profession, and diagnosis of laryngeal disorders in patients with behavioral dysphonia.Study DesignThis is a descriptive, quantitative, field intervention study.MethodsParticipants (n = 26, adult patients of both sexes), with a diagnosis of behavioral dysphonia, received group therapy intervention. Data for risk factors were collected pre- and posttherapy using the Vocal Screening Protocol. The data were analyzed using descriptive and inferential statistics (Student t test, chi-squared test or Spearman correlation test).ResultsThe majority (80.8%, n = 21) of patients were female, 65.4% (n = 17) were not in a vocal profession, and 42.3% (n = 11) presented with a lesion in the membranous portion of the vocal fold. The number of personal risk factors decreased after group therapy (P = 0.04). In addition, age was correlated with total (P = 0.001), environmental (P = 0.002), and personal (P = 0.003) vocal risk factors posttherapy.ConclusionsThis study revealed an association between the reduction of personal risk factors and vocal group therapy, and a correlation between age and total, environmental, and personal vocal risk factors posttherapy. Thus, maintenance and origins of the behaviors that modify the behavioral aspects of the participants directly influence the production of individual vocal habits.
