The purpose of this study was to determine effects of an empowerment education program (EEP) on internet games addiction, empowerment, and stress in middle school students.

The EEP used in this study was based on the Freire's Empowerment Education Model. The research design of this study was a non-equivalent control group pretest-posttest design for 48 middle school students, who were conveniently assigned to an experimental group or a control group. The data were collected from May 29 to June 19, 2005. Data were analyzed using SPSS/PC program with frequencies, χ²-test, Fisher exact test, t-test, mean, standard deviation and ANCOVA.

1) The first hypothesis that, "the experimental group would have higher empowerment scores than the control group." was supported. 2) The second hypothesis that, "the experimental group would have lower internet games addiction scores than the control group." was supported. 3) The third hypothesis that, "the experimental group would have lower stress scores than the control group." was supported.

We suggest, therefore, that the EEP should be used with adolescent to help them control their stress, internet games addiction and to increase their empowerment.

Meta-analysis of this study was to analyze the character of adolescent smoking cessation programs, to calculate the effect size according to variables and to compare the weighted mean effect sizes on adolescent smoking cessation programs in Korea.

Twenty two studies for meta-analysis were selected from dissertations, theses, articles and research papers that had been published from 1995 to 2003. The selected studies had a randomized or nonequivalent control group in a pretest-post test design and had reported statistical value to calculate the effect size.

The mean number of sessions was 6.5. The education time per each session varied from 40 to 150 min and the most applied theories were Bandura's social-cognitive theory and the cognitive-behavioral theory. Smoking-knowledge, smoking-attitudes and smoking-amount showed high effects on the first post test after mediating adolescent smoking cessation programs according to the criteria of Cohen. The effect size of urine-cotinine found no homogeneity on the first post test, but it was significantly effective on the second post test.

Adolescent smoking cessation programs analyzed in this study were relatively effective in smoking abstinence.
