In this study, the authors examined the efficacy of an Internet-based stress management program (1). The program is based on cognitive-behavioral therapy and was inspired by the "Funambule" program in Quebec. Four questionnaires (Perceived Stress Scale, Rosenberg Self-Esteem Scale, Scale of Satisfaction in Studies, and General Health Questionnaire) uploaded online were answered thrice: during "preintervention", "postintervention", and "follow-up" stages, the latter of which occurred three months after the intervention. The sample comprised 128 university students, with the majority being women (81.25%). The self-esteem scores of the control group were significantly higher than those of the experimental group at the preintervention stage, but this difference disappeared at the postintervention and follow-up stages. There were also significantly lower scores on the General Health Questionnaire subfactors of somatic symptoms and anxiety/insomnia in the experimental group than in the control group during the postintervention stage, though no differences were observed before the intervention. These differences no longer remained after three months. The authors conclude that this type of Internet-based program has the ability to reach a large number of students due to its rather short format and accessibility.
