Objective: To investigate an effect of a personal health record booklet (PHRB) to knowledge, self efficacy and healthy behaviors among Thai population at risk of CVD.
Material and Method: The present study was a quasi-experimental study conducted in a primary care unit during November 2008 and January 2009. A random sample of 204 CVD risk population were recruited as a comparison group (n = 102), who received a regular follow-up and recorded routine blood pressure using booklet and an experimental group (n = 102), who received the regular follow-up and the intervention consisting of health education for CVD information and self-monitoring practice. Data were collected by using self-administered questionnaires at the baseline, the 4th week and the 8th week. These data were analyzed by descriptive statistics, Chi-square test and GLM repeated measures.
Results: Knowledge score was significantly decreased although self-efficacy was increased over a time in the experimental group. However, except the figure of sweet/cookies consumption, the mean score of healthy behaviors were not improved in the experimental group when compared to the comparison group.
Conclusion: CVD information, activity illustrations with caption, health record section and daily self-monitoring tables in desired behaviors should be considered for inclusion in the booklet.
