Study protocol of a telephone problem-solving intervention for Spanish-speaking caregivers of veterans post-stroke: an 8-session investigator-blinded, two-arm parallel (intervention vs usual care), randomized clinical trial

Abstract

Abstract Background Stroke is one of the leading causes of death and the main cause of long-term disability in the United States. The significant risk factors of stroke among Hispanics are well-documented. The majority of stroke survivors return home following a stroke and are cared for by family caregivers. Due to the abrupt nature of strokes, caregivers experience unexpected changes and demands that oftentimes lead to caregiver burden and depression. Given the significant risk factors for stroke in Hispanics and the influence of culture in family norms and family management, we developed a telephone and online problem-solving intervention for Spanish-speaking stroke caregivers. This study tests the impact of a telephone and online problem-solving intervention for Spanish-speaking stroke caregivers on caregiver outcomes. Methods The design is a two-arm parallel randomized clinical trial with repeated measures. We will enroll 290 caregivers from 3 Veterans Affairs (VA) medical centers. Participants randomized into the intervention arm receive a problem-solving intervention that uses telephone and online education and care management tools on the previously developed and nationally available RESCUE en Español Caregiver website. In the usual care group, participants receive the information and/or support caregivers of veterans with stroke normally receive through existing VA resources (e.g., stroke-related information and support). The primary outcome is change in caregiver’s depressive symptoms at 1- and 12-weeks post-intervention. Secondary outcomes include changes in stroke caregivers’ burden, self-efficacy, problem-solving, and health-related quality of life (HRQOL) and veterans’ functional abilities. We will also determine the budgetary impact, the acceptability of the intervention and participation barriers and facilitators for Spanish-speaking stroke caregivers. Discussion This is an ongoing study. It is the first known randomized controlled trial testing the effect of a telephone and online problem-solving intervention in Spanish for caregivers of veterans post-stroke. If successful, findings will support an evidence-based model that can be transported into clinical practice to improve the quality of caregiving post-stroke.
