We conclude that the majority of behavior problems associated with theophylline occur during the induction phase, and that for most children behavior and attention problems rapidly return to baseline or improve.

A pre‐post quantitative research design showed that the pre‐contemplation, contemplation and preparation stages progressed significantly after the campaign. The findings suggest that stimuli incorporating specialized information and small action steps allow migration to successive stages. With the strong presence of internet culture among Singap...
