Reduction of Demoralization in Patients With Tardive Dyskinesia After Treatment With Valbenazine

Phase 1
Recruiting
Conditions
Tardive Dyskinesia
Interventions
Registration Number
NCT05053321
Lead Sponsor
Yale University
Brief Summary

This will be an Investigator-initiated pilot study in which participants will be assessed with various scales to measure demoralization, anxiety, depression, and subjective incompetence at baseline and every two weeks after treatment with Valbenazine for a total of 6 weeks. Improvement in TD will be assessed as well and correlated with reduction in demoralization.

Detailed Description

This will be an Investigator-initiated, prospective, single center, interventional pilot study. This study will examine the feasibility of a larger study aimed at determining if there is an association between the improvement in tardive dyskinesia and the reduction in demoralization and subjective incompetence in patients with tardive dyskinesia after treatment with Valbenazine. Participants in that larger study will be treated with Valbenazine for a total of 7 weeks.

Primary Outcome Measures
NameTimeMethod
Change in demoralization ScaleBaseline, week 2, week 4, and week 6

The change in symptoms of demoralization will be measured using the Demoralization Scale-II (DS-II). Scale scores range from 0 (minimum) to 32 (maximum), with higher scores indicating more demoralization (i.e., a worse outcome). Reduction of score to below 10 will be measured

Secondary Outcome Measures
NameTimeMethod
Change in subjective incompetence scale (SIS) scoreBaseline, week 2, week 4, and week 6

The SIS consists of 12 items, each item has 4 response alternatives scored as 0, 1, 2, 3. The scores range from 0 to 36. Higher scores mean more severe subjective incompetence.
