Adolescent depression presents a problem that cannot be ignored in modern society. Motivational interviews for planned health education management are considered a potential intervention method to address this issue.

The study selected adolescent students from several schools as the research subjects and divided them into an experimental group and a control group. The experimental group received motivational interviews on planned health education management, including individual interviews and group discussions; The control group continued to receive routine health education. To clarify the grouping, we used a random sampling method to randomly assign students to two groups. The study collected depression scores and mental health questionnaire survey data from adolescents as research indicators and used Stata statistical software for data processing and analysis.

In the experimental results, the depression scores of the experimental group students were significantly reduced. The depression score of the experimental group students decreased from the initial 25.6 to 18.9, while the depression score of the control group students decreased from the initial 26.3 to 24.5. The results of Stata statistical software showed that the difference between the experimental group and the control group was statistically significant.

The research results indicate that motivational interviews in planned health education management have a positive effect on adolescent depression. Motivational interviews such as individual interviews and group discussions can significantly reduce adolescent depression scores and help alleviate their depressive symptoms.
