Virtual Coaching Trial for Heart Failure Caregivers in the United States

Aggregating data from a randomized controlled trial with 250 enrolled informal caregivers of adults with heart failure, assessing a virtual support health coaching intervention against a control group. Data were collected at baseline, 3 months, and 6 months, measuring self-care, stress, coping, and health status. The trial tested the intervention's efficacy on caregiver outcomes and explored its effect on patient outcomes.

Use Cases

• Analyze changes in self-care maintenance scale and Health Self-Care Neglect (HSCN) scale scores between the intervention and control groups over the 6-month period.
• Model the relationship between perceived stress scale scores (categorized as low, moderate, or high) and caregiver burden or coping strategy scores.
• Examine the correlation between active, avoidance, and minimization coping scores from the ways of coping questionnaire and caregiver health status measured by the short-form 36 scale.
• Assess the impact of baseline sociodemographic and clinical characteristics of caregivers on primary outcome measures like self-care and perceived stress.

Strengths

• Data from a randomized controlled trial design with 250 enrolled participants, providing a basis for causal inference.
• Longitudinal data collection at three time points (baseline, 3 months, 6 months) allows for analysis of change over time.
• Includes multiple validated psychological scales (e.g., self-care inventory, perceived stress scale, ways of coping questionnaire) for measuring key constructs.

Limitations

• Sample size is limited to 250 enrolled caregivers from an initial pool of 667 assessed, which may limit statistical power for some subgroup analyses.
• Primary reasons for ineligibility (e.g., low HSCN score, insufficient caregiving hours) and participant refusal (e.g., perceived time burden) may introduce selection bias.
• The 3-month data collection point was brief and only included one primary outcome measure, limiting the depth of mid-point analysis.
