The effects of interval length between sessions in a hypercholesterolemia education class

This study focused on the effects of different intervals between sessions of a hypercholesterolemia education class on post-intervention outcomes. The same comprehensive group-programme contents on hypercholesterolemia were delivered either monthly (for 6 months) or twice-monthly (for 3 months) by the same teaching professionals in a community setting. The twice-monthly programme included 46 participants (male/female = 7/39, average age: 65.8 years)and the monthly programme consisted of 48(male/female = 9/39, age: 66.4). At the beginning of the study, all subjects belonged to the 'contemplation' stage of diet and exercise habits within the Transtheoretical Model of Change. The stage-matched intervention helped many participants move to the 'action ' stage by 6 months after the last session, especially in the twice-monthly group. The change rate of exercise from the 'contemplation' stage to the 'action' stage was significantly higher in the twice-monthly group (76.1 percent) than in the monthly (54.2 percent ). In both monthly and twice-monthly formats, participants' satisfaction and understanding levels at the end of the programme were high, but were significantly higher in the twice-monthly group. Through favorable lifestyles and higher levels of satisfaction and learning, the twice-monthly format may produce more positive results in cholesterol management than the monthly format, as the shorter period of time makes the programme more intensive.
