Based on the increasing importance of psychosocial factors in medicine, the thesis “Psychosocial aspects in voice therapy for functional dysphonia. Theoretical foundations and qualitative survey of voice therapy practice” deals with the relationships between psychosocial aspects and functional dysphonia, and how voice therapists should regard them. Based on theoretical foundations, voice therapy practice is evaluated by means of a qualitative survey with guided interviews. The question underlying the research is: when and how do Austrian voice therapists take account of psychosocial aspects in therapy for functional dysphonia and which possibilities and limitations do they see in considering these aspects? The results show that psychosocial factors are widely taken into account by direct and indirect means of voice therapy and which measures voice therapists use for each. Moreover, the results show the perceived possibilities and their limitations. The thesis offers a comprehensive insight into voice therapy practice, allowing voice therapists to reflect their own practice, and can be used as a basis for further research in this field.
