Level of Physical Activity Measured by the World Health Organization Global Physical Activity Questionnaire (GPAQ)

Physical activity level assessed using the World Health Organization Global Physical Activity Questionnaire (GPAQ). The GPAQ measures physical activity across work, transport, and leisure domains. Total physical activity is calculated in metabolic equivalent task minutes per week (MET-minutes/week). Higher scores indicate higher levels of physical activity.

Time frame: Baseline (Week 0) and post-intervention (Week 13)

Intention to Quit Smoking Measured by the Intention to Quit Smoking Scale (IQSS)

Smoking cessation intention was assessed using the Intention to Quit Smoking Scale (IQSS) developed by Söyler and Yorulmaz (2024). The IQSS is a self-reported questionnaire consisting of multiple items rated on a Likert-type scale. Total scores range from 8 to 40, with higher scores indicating a stronger intention to quit smoking.
