Health Belief Model-Based Telenursing for Hypertension

This randomized controlled trial evaluated the effects of a Health Belief Model-based telenursing intervention on self-efficacy, quality of life, blood pressure, body mass index, and health behaviors in individuals with hypertension. A total of 78 participants were randomly assigned to the intervention group (n=39) or control group (n=39). Participants in the intervention group received a 12-week telenursing intervention based on the Health Belief Model, including face-to-face education, training on home blood pressure monitoring, educational materials, weekly text messages, and telephone follow-up at weeks 2, 4, 8, and 12. The control group received usual care. Outcomes were assessed at baseline, 3 months, and 6 months.

Treatment and study plan

Health Belief Model-Based Telenursing Intervention

Behavioral

The intervention consisted of Health Belief Model-based education and a 12-week telenursing follow-up program. Participants received four telephone follow-up calls at weeks 2, 4, 8, and 12, each lasting approximately 10-15 minutes. Weekly text messages were sent for 12 weeks to remind participants about blood pressure monitoring and to provide information about hypertension management. Participants could also contact the researcher when they needed additional support.

Primary outcomes

  1. Hypertension Self-Efficacy

    Time frame: Baseline, 3 months, and 6 months

    Hypertension self-efficacy was assessed using the Hypertension Self-Efficacy Scale (HSES). The scale consists of 20 items, with higher scores indicating higher hypertension self-efficacy.

  2. Health-Related Quality of Life

    Time frame: Baseline, 3 months, and 6 months

    Health-related quality of life was assessed using the 12-Item Short Form Health Survey (SF-12), which provides Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Higher scores indicate better health-related quality of life.

Secondary outcomes

  1. Systolic Blood Pressure

    Time frame: Baseline, 3 months, and 6 months

    Systolic blood pressure was measured in mmHg. Blood pressure measurements were obtained to evaluate changes in systolic blood pressure during the study.

  2. Diastolic Blood Pressure

    Time frame: Baseline, 3 months, and 6 months

    Diastolic blood pressure was measured in mmHg. Blood pressure measurements were obtained to evaluate changes in diastolic blood pressure during the study.

  3. Body Mass Index

    Time frame: Baseline, 3 months, and 6 months

    Body mass index (BMI) was calculated as body weight in kilograms divided by height in meters squared (kg/m²).
