Question 110

A study was conducted to compare the effectiveness of two stress-reduction interventions over a 4-week period. Participants in Group 1 used a mobile Mindfulness App daily, while participants in Group 2 practiced structured Deep Breathing Exercises daily. Stress levels were measured both before and after the 4-week intervention using a self-report compliance questionnaire (where a higher score indicates higher stress levels).
