Content validity and satisfaction with a stroke caregiver intervention program.

Area of Science:

• Rehabilitation and Allied Health
• Nursing Intervention Research
• Gerontology and Stroke Care

Background:

• Establishing content validity and user satisfaction is crucial for intervention research.
• Stroke caregiver needs require tailored support programs.
• The Telephone Assessment and Skill-Building Kit (TASK) is an 8-week intervention designed for stroke caregivers.

Purpose of the Study:

• To describe the content validity of the TASK intervention.
• To evaluate caregiver satisfaction with the TASK intervention.
• To assess the TASK intervention's effectiveness compared to an attention control group.

Main Methods:

• Ten experts evaluated the TASK intervention's accuracy, feasibility, acceptability, and problem relevance.
• A randomized controlled trial involved 40 stroke caregivers assessing satisfaction (usefulness, ease of use, acceptability).
• Data were analyzed using descriptive statistics, independent sample t tests, and content analysis.

Main Results:

• Experts provided strong evidence of content validity for TASK components (accuracy 4.71, feasibility 4.46, acceptability 4.40, problem relevance 4.67).
• TASK group caregivers reported significantly higher satisfaction than the control group (usefulness p=.02; ease of use p=.02; acceptability p=.05).
• Qualitative caregiver comments corroborated findings of high satisfaction.

Conclusions:

• The TASK intervention demonstrated significant content validity and user satisfaction.
• The TASK program is a viable, telephone-based support option for nurses.
• This intervention can effectively support family caregivers of stroke survivors post-discharge.
