This study examined influences of subjective adjustment to university life on self-expression among first-year university students in the early stages of university entrance. In Study 1, factor analysis results of the self-expression scale revealed three factors: “expression of favorable feelings,” “expression of proactive intentions,” and “expression of help-seeking.” In Study 2, the questionnaire survey results showed that: “expression of proactive intention” to family members was the highest regardless of timing or subjective adjustment to university life and “expression of helpseeking” to family members was highest in May regardless of subjective adjustment. Additionally, “expression of help-seeking” to friends was higher in July than in May regardless of subjective adjustment and higher in July for students with high subjective adjustment than for students with low subjective adjustment. “Expression of favorable feelings” toward friends was most expressed regardless of subjective adjustment or timing. In July, “expression of help-seeking” towards people they do not normally interact with was higher for students with high subjective adjustment than those with low subjective adjustment. As support for first-year university students, regular contact with family members and friendship formation should be promoted, and opportunities to connect with students they do not normally interact with should be provided.
