Overview

This study will be conducted to compare the effects of Peer- and Nurse-Led Health Protection and Promotion Training Programs Based on Social Cognitive Theory (SCT) on the health behaviors of older adults. This research will be carried out in two stages as a mixed-methods study with an embedded mixed-method design. The first stage has been planned as a parallel two-arm non-randomized experimental study. This stage will be conducted between October and December 2025 in two separate elderly homes where older adults are densely located in the Muratpaşa district of Antalya province. The sample size has been calculated as 108 older adults (Intervention-1 Peer Leadership: 54, Intervention-2 Nurse Leadership: 54). In the Intervention-1 group, the intervention will be implemented for 12 weeks through the Health Protection and Promotion Training Program Based on SCT under peer leadership, and the same interventions will be carried out in the Intervention-2 group under nurse leadership. Outcomes will be measured before the intervention and 12 weeks after the intervention using the Elderly Health Promotion Scale, Health Protection and Promotion Behavior Checklist, General Self-Efficacy Scale, and Health Seeking Behavior Scale. In the second stage, in order to evaluate the intervention process and experiences multidimensionally, it is aimed to deeply understand the experiences of older adults receiving peer-led intervention, older adults receiving nurse-led intervention, and peer leaders by using multiple data sources within the framework of qualitative research and a phenomenological approach. In the qualitative phase, the data will be collected based on the maximum variation sampling method through face-to-face in-depth individual interviews using semi-structured interview forms in the workshops of both elderly homes in January 2026.

Peer-Led Health Protection and Promotion Training ProgramBEHAVIORAL

The Peer-Led Health Protection and Promotion Training Program based on SCT aims to improve health behaviors, increase self-efficacy, and promote appropriate health-seeking behaviors among older adults with low or moderate levels of health promotion practices. Implemented in the Intervention-1 group, this program is defined as the ÖNDER (Self-efficacious Individuals-Qualified Guidance-Experience Sharing-Active Participation-Role Model) Program and was developed according to the Taba-Tyler Model. The program includes interactive group education; demonstration and guided use of Google Fit and E-Pulse applications; WhatsApp groups for peer interaction; peer walking activities; individual phone calls; digital reminders (messages, brochures, videos); peer meetings; and achievement badges. Interventions will be conducted by peer leaders in the workshop classroom and garden of the elderly home.

Health Protection and Promotion Training Program under the Leadership of a Public Health NurseBEHAVIORAL

The SCT-based Nurse-Led Health Protection and Promotion Training Program implemented in the Intervention-2 Nurse Leadership group has the same aim, duration, and weekly plan as the Intervention-1 Peer Leadership group and is conducted under nurse leadership. The program applied to the Intervention-2 Nurse Leadership group is briefly defined as the REHBER (Reflection-Education-Nurse Leadership-Information-Activation-Routine Formation) Program. The SCT-based Health Protection and Promotion Training Program provided to this group was also developed according to the Taba-Tyler Model.

Outcomes

Primary Outcomes

Elderly Health Promotion Scale

The Elderly Health Promotion Scale, developed by Wang et al. (2015), assesses health-promoting behaviors in individuals aged 65 and over and consists of 22 items and six subdimensions. Its Turkish validity and reliability were established by Gulsoy and Senturan (2020). The subdimensions include Health Behaviors, Participation in Society, Health Responsibility, Healthy Eating, Regular Exercise, and Oral Health. The four-point Likert scale ranges from "never" (1) to "always" (4), with total scores between 22 and 88; higher scores indicate greater engagement in health-promoting behaviors. Subscale scores are obtained by summing relevant items. Cronbach's alpha coefficients ranged from 0.80 to 0.91 for subdimensions, with an overall reliability of 0.85 (Gulsoy and Senturan, 2020).

Health Promotion and Prevention Behavior Checklist

This form was developed based on the literature to assess health promotion and prevention behaviors among individuals aged 65 and over (Gulsoy and Senturan, 2020; Ministry of Health, 2023). It includes items on the Elderly Health Promotion Scale, immunization, chronic disease screenings, smoking, obesity, and cancer screenings. Responses are coded as "Yes: 1" and "No: 0." Based on total scores, behaviors are classified as low, moderate, or high, with gender-specific cut-off points. Additionally, health promotion behavior is evaluated as insufficient or sufficient according to the scale score. Content validity was established using the Davis technique with input from 10 experts, yielding a high CVI of 0.96 (Davis, 1992).

General Self-Efficacy Scale

The General Self-Efficacy Scale, developed by Jerusalem and Schwarzer and later revised to 10 items, was adapted into Turkish by Aypay (2010). It is a four-point Likert scale (1=not at all true to 4=completely true), with total scores ranging from 10 to 40; higher scores indicate greater self-efficacy. The Cronbach's alpha coefficient is 0.83.

Health-Seeking Behavior Scale

The Health-Seeking Behavior Scale, developed by Kirac and Ozturk (2021), consists of 12 items across three subdimensions: online, professional, and traditional seeking behaviors. It is a five-point Likert scale (1=strongly disagree to 5=strongly agree), where higher mean scores indicate greater health-seeking behavior. The scale's Cronbach's alpha coefficient is 0.76.

Secondary Outcomes

Google Fit Mobile Application Use Checklist

The Google Fit Mobile Application Use Checklist consists of six items assessing the ability to log into the mobile application, start the application while walking, access the average walking duration (daily, weekly, and monthly) through the application, and set walking goals (in terms of duration). The responses to the checklist, which was developed based on the features available in the mobile application, were recorded as "Yes" and "No," and the use of the Google Fit mobile application among older adults was evaluated using an objective measurement tool.

E-Pulse Mobile Application Use Checklist

The E-Pulse Mobile Application Use Checklist consists of 24 items and was developed based on the features available in the E-pulse mobile application. The responses to this checklist were recorded as "Yes" and "No," and the use of the E-Pulse mobile application among older adults was evaluated using an objective measurement tool.
