Primary outcome measures |
Feasibility: Recruitment rate (per month), randomization success, blind success, retention/attrition rates |
Acceptability: Likert scale (from 0 [strongly disagree] to 10 [strongly agree]) composed of ten affirmatives regarding the use of home-based tDCS. For example, question 1: “It was easy to prepare the device and accessories,” question 7: “I felt confident using the device.” Overall acceptability across groups will be evaluated by descriptive measures of satisfaction ratings [31] |
Safety: Side effects questionnaire that include itching, burning, headache, fatigue, and dizziness [31] |
