Research identifies academic workload as a major source of stress in high school students and self-organization as a criterion of psychological well-being. A survey involved 202 students in grades 9–11, using the PSM-25 scale by Lemur, Tessier and Fillion in Vodopyanova’s Russian adaptation, together with measures of self-organization and time management. Statistical differences were assessed using Pearson’s chi-squared test for 2 × 2 contingency tables. Low stress was found in 52% of students and moderate or high stress in 48%. Self-organization scores outside the normal range occurred in 52.4% of the low-stress group and 52.6% of the moderate- or high-stress group. No statistically significant differences were found. The authors conclude that self-organization does not affect stress levels in this sample and advocate a comprehensive approach incorporating social support, physical activity and time management skills.
