Abstract:
The purpose of this quasi-experimental study was to evaluate the effect of a consumer health promoting program on cosmetics usage behavior among students based on Protection Motivation Theory in secondary educational service area office 1 Bangkok. The samples were randomly recruited from two schools in secondary educational service area office 1 Bangkok. One school was assigned to an experimental group received the program, and the another school was assigned to a control group, 35 students of each school were randomly recruited into the study groups. The study period was nine weeks with 5 weeks for intervention period and 4 weeks for follow-up period. Data were collected using self-administered questionnaires, developed by the application of the protection motivation theory including perceived severity of harmful cosmetics usage, perceived susceptibility, self-efficacy expectation, outcome expectation of cosmetics usage, and intention to practice of harmful cosmetics usage protection. Statistical analysis was performed by using percentage, mean, standard deviation, Independent t-test, and Paired t-test. The results revealed that, after intervention period the experimental group had significantly higher perceived severity, perceived susceptibility, self-efficacy expectation, and outcome expectation mean scores than the control group (p < 0.05). However, no significant differences in intention to practice of harmful cosmetics usage protection were found between the experimental and the control group. No statistical significant changes were found in the control group. ช The cosmetics usage behavior promoting program had the potential to increase perceived severity, perceived susceptibility, self-efficacy expectation, and outcome expectation in preventing harmful cosmetics usage and leading to have an increasing safe cosmetics usage behavior among students.
