Evaluating the Feasibility and Preliminary Effects of BE+

This non-randomized, single group study will test a 12-week, behavioral intervention for physical activity and stress management for survivors of non-small cell lung cancer (NSCLC) and a partner (family member or friend). The goals of this intervention, Breathe Easier+ (BE+), are to increase overall physical activity and overall fitness and to reduce symptoms (fatigue, breathlessness, sleep, and stress). The aim of this study is to evaluate the enrollment, retention, adherence, participation, and acceptability of the 12-week BE+ among NSCLC survivors and their partners. The study also aims to: 1. Explore preliminary intervention effects of BE+ on increasing physical activity and overall fitness (measured by 7-day Fitbit wear, step-in-place test, chair sit-and-stand, arm curl test, and balance test) from baseline to post-intervention among NSCLC survivors and their partners. 2. Explore preliminary effects of BE+ for improvement in stress response, symptom burden (fatigue, dyspnea), sleep, and HRQL from baseline to post-intervention among NSCLC survivors and their partners. Participants will receive education, social support, coaching, a guided walking program, supervised resistance training (RT), and meditations delivered via digital technology (tablet, smartphone, and Fitbit).

Effect of a Mobile-Based Hydration Tracking Program on Knowledge, Attitudes, and Behaviors in Older Adults

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.

Health Behavior Nudge Strategies for Chronic Disease Patients: the Study of Hypertension and Type 2 Diabetes

This study is conducted from the perspective of behavioral economics, where individuals often display bounded rationality in decision-making, opting for habitual choices rather than those most advantageous to themselves. Nudge strategies can utilize individuals\' cognitive and motivational shortcomings to influence behavior. Therefore, the study first examines the decision-making biases present in patients with hypertension (HP) and type 2 diabetes mellitus (T2DM) regarding the maintenance of healthy behaviors based on individuals' bounded rationality; subsequently, it develops an intervention program to encourage healthy behaviors in HP and T2DM patients alongside nudge strategies; finally, it assesses the intervention effects of the program on blood pressure, blood glucose, and health behaviors in HP and T2DM patients.
