Brief Summary

This randomized controlled trial aims to evaluate the impact of a mobile-friendly, web-based hydration tracking application (named "SIVI") on hydration-related knowledge, attitudes, and behaviors in older adults. Inadequate fluid intake is a common and modifiable risk factor for dehydration in the elderly, leading to increased morbidity, hospitalizations, and functional decline. However, many older individuals forget to drink fluids or face barriers such as fear of incontinence, mobility limitations, or cognitive challenges. This study will include 70 community-dwelling older adults aged 65-84 years, recruited from a Family Health Center. Participants will be randomly assigned to either the intervention or control group. The intervention group will use the SIVI application for two months. The app is specially designed for older adults and includes features such as personalized fluid goals, reminders, hydration education modules, feedback, and a user-friendly interface with large fonts and high contrast. Participants will log their daily fluid intake, receive motivational messages, and access videos and information about healthy hydration habits. A water bottle will be provided to standardize measurement across groups. The control group will receive only routine care. Both groups will complete questionnaires measuring demographics, hydration knowledge, attitudes, behaviors, and fluid consumption habits at baseline, one month, and two months. Data collection will be conducted face-to-face by the researcher, and analysis will be performed using SPSS 22.0. Statistical tests will include descriptive statistics, Shapiro-Wilk for normality, chi-square for categorical data, and t-tests and ANOVA for comparisons over time. The results are expected to show that the SIVI application improves older adults' hydration knowledge, fosters positive attitudes, and promotes healthy fluid intake behaviors, thus supporting self-management of hydration and potentially reducing dehydration-related health risks.

Outcome Measures

Primary Outcomes (1)

• Hydration Knowledge, Attitude, and Behavior Scale Scores

  Participants' hydration-related knowledge, attitude, and behavior will be assessed using the Turkish version of the Hydration Knowledge, Attitude, and Behavior Scale (HyKS). The scale includes 16 knowledge items, 18 attitude items, and 4 behavior items. Scores are calculated separately for each domain. Higher scores indicate improved knowledge, more positive attitudes, and healthier hydration behaviors.

  Baseline and 8 weeks after the intervention

Secondary Outcomes (1)

• System Usability Score of the Mobile Hydration Tracking Application

  Week 4 and Week 8 after intervention

Other Outcomes (1)

• Fluid Intake Habits Based on Self-Reported Form

  Baseline, Week 4, and Week 8

Study Arms (2)

Arm 1: Intervention Group

EXPERIMENTAL

Participants in this group will receive individualized face-to-face training and use the mobile-compatible, web-based hydration tracking application (SIVI) daily for 8 weeks. They will receive reminders, set personalized fluid intake goals, track their daily intake using visual tools, and access educational materials through the app. A standard water bottle will also be provided for consistent measurement.

Behavioral: Mobile-Compatible Web-Based Hydration Tracking Program

Arm 2: Control Group

NO INTERVENTION

Participants in this group will receive rutine care. They will not receive access to the SIVI application or any structured follow-up. A standard water bottle will also be provided for intake tracking purposes.

Interventions

Mobile-Compatible Web-Based Hydration Tracking Program BEHAVIORAL

Intervention Description: The SIVI Hydration Application is a mobile-compatible, web-based behavioral intervention designed specifically for older adults. It supports self-monitoring and self-management of daily fluid intake through features such as personalized fluid goals, visual drink-logging with icons, daily reminders, progress graphics, educational videos, and motivational digital badges. The app was developed using gerotechnology and universal design principles to accommodate cognitive and sensory changes common in aging. Its unique focus on hydration behavior, combined with usability features like large fonts, high contrast, and voice-assisted guidance, distinguishes it from general health or diet tracking apps. Participants use the app for 8 weeks as part of a structured intervention with training and weekly follow-up.
