Table 2 Differences in SPSI-R and subscales among categories of physical activity

From: Attitude and practice of physical activity and social problem-solving ability among university students

  Physical activity P value
Do not exercise Exercise but not regularly Exercise regularly
And never think about doing so But intend to start Try to exercise
