Background and Objectives: This study evaluated the effectiveness of a web-based stress management program among community college students that focused on increasing perceived control over stressful events. Design: Students (N = 257) were randomly assigned to a Present Control Intervention or a Stress-information only comparison group. Methods: Primary outcomes were perceived stress and stress symptoms; secondary outcomes were depression and anxiety. Self-report measures were completed online at preintervention, postintervention, and three-week follow-up. Intervention effects were estimated using linear mixed models. Seventy-five percent of the sample (n = 194) completed the pretest and comprised the intent-to-treat sample. Results: Participants in the intervention group reported significant increases in present control, and significant decreases in all four primary and secondary outcome measures from baseline to postintervention and follow-up. Within-group effect sizes were small to medium at postintervention (mean d = -.34) and follow-up (mean d = -.49). The mean between-group effect size on the four outcome measures was d = .35 at postintervention but d = .12 at follow-up, due to unexpected decreases in distress in the comparison group. Conclusions: Our online program is a cost-effective mental health program for college students. Limitations and future direction are discussed. [ABSTRACT FROM AUTHOR]
