The purpose of this study was to develop a computer-based cognitive behavioral therapy program for weight control in obese women and prove its efficacy. The subjects of this study were chosen from obese women whose BMI scores were above 23 and who had no other clinical problem except obesity. The 8 person for each group were randomly assigned into an experimental group, a comparison group(received a computer?based behavioral control program) and a control group. For the therapy, participants connected to designated computer-based websites and completed assignments twice a week for 8 weeks. The main findings of this study are as follows. First, BMI score for the comparison group significantly decreased at the posttest assessment while the score for the experimental group decreased significantly at the 3-month and 1-year follow-up tests. Second, after receiving the program, the experimental group was marked with significant increase in the expected target weight while the level of irrational beliefs and negative automatic thoughts decreased. Self-efficacy of health increased for both experimental group and comparison group after the program, while psychological efficacy increased only for the experiment group, and the effect was maintained at the 3-month and 1-year follow-up tests. Third, after receiving the program, the experimental group showed decrease in the level of depression and unrest, and the effect was maintained at the 3-month and 1-year follow-up tests. Fourth, after receiving the program, the experimental group showed decrease in the level of general problematic feeding behavior, and the effect was maintained at the 3-month and 1-year follow-up tests. For the comparison group, the level of external feeding decreased after the program, but emotional feeding and restrained feeding were found to increase at the 3-month and 1-year follow-up tests. In case of stress coping strategies, problem-focused coping strategy increased while relaxing-emotion strategy and wishful thinking strategy decreased for the experimental group. Social support-seeking strategy of the experimental group was also found to increase at the 1-year follow-up test. For the comparison group, problem-focused coping strategy increased while wishful thinking strategy decreased after the program. However, at the 1-year follow-up test, wishful thinking strategy was found to increase significantly. The control group, at the posttest, was not marked with significant changes in all of the variables except for the level of health promotion which, actually, was marked with a significant decrease. This study is significant in the fact that it attempted a new way of conducting CBT with an online-based method rather than a traditional face-to-face method by developing and conducting a computer-based CBT program and verifying its effect as a preliminary study.
