Summary:
This study aims to explore the feasibility and preliminary effectiveness of a mobile phone-based intervention among elderly individuals with chronic diseases.

Primary Outcome Measures: Time spent in sedentary behavior, The time spent sedentary behavior (min/week) in the last 7 days, 3 and 6 months follow-up|Acceptability of the Mobile Phone-Based Intervention, Acceptability will be assessed using a series of 4 items from previous studies on mobile physical activity interventions. Participants will rate each statement on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). The statements will cover aspects such as ease of use, personal relevance, clarity of information, and overall satisfaction with the intervention., 3 and 6 months follow-up|Perceived Usefulness of the Mobile Phone-Based Intervention, Perceived usefulness will be assessed using 5 items from previous studies on online physical activity interventions. Participants will rate each question on a 5-point Likert scale, ranging from 1 (not at all useful) to 5 (very useful). The questions will explore how useful participants found the intervention in helping them to (1) increase confidence in engaging in regular physical activity, (2) overcome barriers to physical activity, (3) increase support for participating in physical activity, (4) plan for physical activity, and (5) stay motivated to engage in physical activity., 3 and 6 months follow-up
Secondary Outcome Measures: Time spent in zero-time exercise, The time spent physical activity while seated and standing (min/week) in the last 7 days, 3 and 6 months follow-up|Exercise self-efficacy, This outcome measure evaluates participants' confidence in their ability to engage in regular physical activity (self-efficacy). Participants will rate their confidence on a single-item scale ranging from 1 to 10, with higher scores indicating greater self-efficacy., 3 and 6 months follow-up|Anxiety and depression, Anxiety and depression levels will be assessed using the Patient Health Questionnaire-4 (PHQ-4), a validated tool comprising two items for anxiety and two items for depression. The PHQ-4 score ranges from 0 to 12, with higher scores indicating greater severity of anxiety and depression symptoms., 3 and 6 months follow-up|Perceived subjective happiness, This outcome measure assesses participants' subjective happiness using a Self-Reported Happiness scale. Participants will rate their happiness on a single-item scale ranging from 1 (not at all happy) to 5 (extremely happy), with higher scores indicating greater perceived happiness., 3 and 6 months follow-up|Perceived life satisfaction, This outcome measure assesses participants' subjective life satisfaction using a self-reported life satisfaction scale. Participants will rate their life satisfaction on a single-item scale ranging from 1 to 5, with higher scores indicating greater perceived life satisfaction., 3 and 6 months follow-up
