Brief summary
This study aims to investigate whether there is a difference between groups receiving group voice therapy and individual voice therapy in pediatric populations diagnosed with dysphonia. In this context, the goal is to comprehensively examine the effectiveness of group voice therapy in pediatric populations compared to similar studies in the literature. In line with this objective, it is aimed to comprehensively test its effectiveness by including perceptual and acoustic evaluation findings, objective and subjective assessments, and incorporating comparison and control groups into the study, as compared to similar studies in the literature.
Detailed description
There are three groups in total in the study: two research groups and one control group. The first research group will receive group voice therapy. Group voice therapy sessions are arranged in groups of three. A total of eight sessions will be given, one session per week. The second research group will receive individual voice therapy. In this context, participants will be given individual voice therapy for a total of eight sessions, one session per week. The voice therapy approach to be applied to participants receiving individual voice therapy and group voice therapy includes direct and indirect voice therapy methods.Control group participants will receive a one-session vocal hygiene training. Control group participants will be evaluated before and after vocal hygiene training. The first and second research groups will be evaluated four times in total: before therapy, after therapy, third month follow-up and sixth month follow-up. It is aimed to examine the effectiveness of group voice therapy by comparing the findings obtained from the approaches. Objective and subjective evaluation tools will be used in the evaluations. It is expected that Research Group 1, receiving group voice therapy, and Research Group 2, receiving individual voice therapy, will demonstrate a significant decrease in the primary outcome measure, the GRBAS score, and secondary outcome measures, including the Pediatric Voice Handicap Index score, the Teacher's Perception-Based Voice Handicap Index score, and a significant increase in the Pediatric Voice-Related Quality of Life Scale score when comparing pre-therapy and post-therapy assessments. It is anticipated that these significant changes will be sustained in the follow-up evaluations.
Interventions
BEHAVIORALGroup Voice Therapy
The group voice therapy intervention consists of a total of eight sessions. The session contents include both direct and indirect voice therapy approaches. Each group is composed of three participants. The session durations are planned to be 45-60 minutes each.
BEHAVIORALIndividual Voice Therapy
The individual voice therapy intervention consists of a total of eight sessions. The session contents include both direct and indirect voice therapy approaches. The session durations are planned to be 45-60 minutes each.
BEHAVIORALVocal Hygiene Education
Regarding vocal hygiene training, information related to voice production and respiratory characteristics will be provided, and guidance on correct and incorrect voice use will be given.

Masking description
The allocation of participants to groups will be carried out through stratified sampling based on the Grade parameter of the GRBAS scoring. Accordingly, individuals conducting GRBAS scoring will listen to the recordings of participants in an anonymous manner.
Intervention model description
Participants will be grouped based on the Grade scores on the GRBAS scale using a stratified sampling method.
