Brief summary

A randomized controlled trial that uses a Stage-matched intervention based on the Transtheoretical Model of Change to enhance engaging in regular physical exercise among high school female students.

Detailed description

A randomized controlled trial that uses a Stage-matched intervention based on the Transtheoretical Model of Change to enhance engaging in regular physical exercise among high school female students. The researchers will use two groups (study and control) in which participants will be randomly selected and assigned in each of the study and control groups using simple random sampling. The study intervention will be designed based on each Stage of Change of the Transtheoretical Model of Change in that participants in each Stage of Change will receive the intervention that matches the Stage of Change they would be in. A 12-week interval would be considered between administering the intervention and posttest 1 and the same interval would be used between posttest 1 and posttest 2.
