SMS Reminders for Exercise Among Older Adults. Malaysian Physical Activity for Health Study

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is: 1) To evaluate the efficacy and feasibility of an SMS reminder intervention for promoting an health-related exercise programme (myPAtHS) among older Malaysian adults, in a randomized controlled trial (RCT). Hypothesis: Frequency and duration of the exercise programme execution will be higher for the SMS reminder condition compared to the programme only condition. The effect may be reduced from post- to follow-up measurement (24 weeks after baseline and 12 weeks after post-measurement) but all outcomes will remain significantly higher at 24 weeks.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of myPAtHS exercise sessions. | This will be assessed with an exercise diary. | 12 weeks & 24 weeks | 
| Time spent doing the myPAtHS exercise programme. | This will be assessed with an exercise diary. | 12 weeks & 24 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in overall physical activity. | The International Physical Activity Questionnaire (short version) will be used to collect physical activity data. | baseline, 12 weeks & 24 weeks | 
| Change in exercise self-efficacy. | The Exercise Self-Efficacy-Scale will be used to collect exercise self-efficacy data. | baseline, 12 weeks & 24 weeks | 
| Change in grip strength. | Grip strength will be assessed using the North Coast strength dynamometer (North Coast Hydraulic Hand Dynamometer, North Coast Medical Inc, Morgan Hill, California, USA). | baseline, 12 weeks & 24 weeks | 
| Change in leg-strength. | Leg-strength will be collected using the 30 seconds chair-stand-test. | baseline, 12 weeks & 24 weeks | 
| Subjective intensity while doing the myPAtHS exercise programme. | This will be assessed with an exercise diary. | 12 weeks & 24 weeks |
