Dysphonia, Distress, and Perceived Control: Technology Based Assessment and Intervention

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to pilot test a version of the intervention that has been tailored for participants with dysphonia. The study seeks to determine if the adapted intervention: a) increases perceived control over voice-related stressors and b) decreases stress and distress resulting from voice problems. The study will also explore the usability and acceptability of the program. The goal is to help people with voice problems achieve better voice and quality of life outcomes.

Detailed Description
-----------------
In the investigator's voice clinic, a high prevalence of severe distress has been identified. Distress and voice handicap were positively correlated, and perceived control moderated the relationship. Perceived control is associated with less distress in a variety of medical conditions, has an impact beyond that of coping and personality, and can be increased via targeted intervention. This is a randomized controlled trial. Participants will be randomly assigned to one of the two groups. Both groups involve completing surveys and receiving information online about voice problem. Participants complete an initial baseline assessment focused on voice function and emotions, including items from the Perceived Control Scale, Voice Handicap Index-10, Perceived Stress Scale, Brief Symptom Inventory-18. Finally, the participants will complete some brief feedback questions about the material. Next, twice a week for up to three weeks participants will complete check-ins from the online program. Participants in the intervention arm will complete self-guided exercises and brief assessment questions. Participants in the information-only arm will complete mini knowledge quizzes. All participants will complete brief a post-intervention assessment parallel to the baseline assessment. Lastly, they will have an opportunity to provide final feedback on their experience. Follow-up with each participant will occur one and three months after finishing the program. Questionnaires will be sent via email including Voice Handicap Index-10, Present Perceived Control-8, and questions regarding treatment adherence and voice outcomes.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Patients who are seen at the Otolaryngology Clinic (University of Minnesota Health Clinics and Surgery Center, or Fairview Hospital Maple Grove or Southdale) with Muscle Tension Dysphonia Patients between 18-80 years of age experiencing a voice problem Scored high (>10) on the Voice Handicap Index (VHI-10) Has the ability to complete informed consent process Interested in using an online program/intervention Has reliable access to internet Exclusion Criteria: Patients who have clinical need for concurrent treatment will be excluded to decrease confounding introduced by having multiple simultaneous interventions. This may include: Concurrent laryngeal lesion requiring immediate operative or other intervention Concurrent participation in speech therapy Concurrent need for new medications that may directly affect voice-related symptoms Participant has a Speech Language Pathology visit scheduled in two weeks or less from when they will start the program (if applicable) Unable to read English (as determined by their ability to complete the clinic intake forms) Female and pregnant Prisoner Unable to provide informed consent (e.g., patients with dementia)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: VOICE Intervention Arm<br>Participants participate in the online VOICE program to learn about perceived control and stress reduction to improve voice outcomes. | Behavioral: VOICE Intervention Arm<br>* Introductory and background information about voice problems and psychosocial distress Examples of concerns raised by patients with voice problems (e.g., I feel left out of conversations because of my voice problem) Information about perceived control and how improving perceived control can lead to decreased distress Examples of strategies that have helped patients identify controllable and uncontrollable aspects of their voice problems (e.g., I learned to plan to take breaks to rest my voice between teaching classes) Self-guided exercises designed to help improve perceived control and develop better management skills for voice problem symptoms<br>|
| Sham Comparator: Information-Only Arm<br>Participants participate in the information only program to learn about voice problems, anatomy and physiology. | Behavioral: Information-Only Arm<br>* General introduction of the program and background on voice related information in an interactive manner Examples of what patients want to learn more about the voice (e.g., I would like to learn more about how the voice works when it is healthy) Information on the anatomy of the voice and how the voice works Educational materials to help understand voice physiology and function Self-guided learning exercises (e.g., what are some things about vocal function that you would like to learn more about?)<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Perceived Control | Change from baseline assessment using a questionnaire, Perceived Present Control-8 (PPC-8). The PPC-8 questionnaire has 8 questions about perceptions of present control over their voice problem, assessed on a 4-point Likert-type scale, with scores of 1-4 (1=Strongly Disagree, 2=Disagree Somewhat, 3=Agree Somewhat, 4=Strongly Agree). Total scores range from 1-32. Higher scores indicate more perceived control over the patient's voice problems. | 2 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Voice Handicap | Change from baseline assessment using a questionnaire, Voice Handicap Index-10 (VHI-10). The VHI-10 questionnaire has 10 questions about voice problems and the effect it has on the patients life, assessed on a 4-point Likert-type scale, with scores of 0-4 (0=Never, 1=Almost Never, 2=Sometimes, 3=Almost Always, 4=Always). Total scores range from 0-40. Higher scores indicate a more problematic voice. The clinical cutoff for a problematic voice is a VHI-10 score of 10, where scores >10 indicate voice problems. A change of at least 6 points is clinically significant. | 2 weeks | 
| Perceived Stress | Change from baseline assessment using a questionnaire, Perceived Stress Scale-4 (PSS-4). The PSS-4 questionnaire has 4 questions about perceived stress, assessed on a 5-point Likert-type scale, with scores of 0-4 (0=Never, 1=Almost Never, 2=Sometimes, 3=Fairly Often, 4=Very Often). Total scores range from 0-16. Higher scores indicate more perceived stress in the patient's life. | 2 Weeks | 
| Psychological Symptoms | Change from baseline assessment using a questionnaire, Brief Symptom Inventory-18 (BSI-18). The BSI-18 questionnaire has 18 questions about psychological symptoms, assessed on a 5-point Likert-type scale, with scores of 0-4 (0=Not at all, 1=A little bit, 2=Moderately, 3=Quite a bit, 4=Extremely). Total scores range from 0-72. Higher scores indicate more extreme psychological symptoms. Patients with High Risk psychological symptoms have a score of 57 (75 percentile) or greater. | 2 weeks |
