EFFECTIVENESS OF A CLASS-FOCUSED INTERVENTION PROGRAM IN IMPROVING SHORT-FORM VIDEO USE BEHAVIORS AND MENTAL HEALTH IN ADOLESCENTS.

Abstract

This study investigated the effectiveness of a class-focused intervention program on short-form video (SFV) use behaviors and mental health in adolescents. A sample of 100 eighth-grade students from two parallel classes at a public junior high school in Xuchang City, Henan Province, China, was recruited. The experimental group (n=50) received a two-month embedded curriculum and group activity intervention, while the control group (n=50) underwent routine management. Results indicated that the experimental group showed a significant 21.2% reduction in entertainment-focused SFV usage time, an 18.1% decrease in anxiety scores, and a 33.3% increase in information-focused SFV usage time post-intervention, all significantly superior to the control group (p < .05). This school-based program requires no family-school collaboration, providing a feasible intervention pathway for resource-limited educational settings.
