Based on self-determination theory, this study examined how basic psychological need satisfaction influenced job search intensity among Chinese graduating college students. A two-wave longitudinal survey was conducted with a sample of 244 graduating students (50.4% female; mean age = 21.44 years, SD = 0.85). Data were collected using the Basic Psychological Need Satisfaction and Frustration Scale, the Goal Orientation Scale, the College Students’ Job Search Stress Scale, and the Job Search Behavior Scale. The results showed that higher basic psychological need satisfaction predicted greater job search intensity, and this relationship was partially mediated by stronger mastery goal orientation. However, the positive association was weakened under conditions of high job search stress. These findings highlight the interplay between internal motivation and external stress in shaping job search behavior, extending our understanding of the drivers of job-searching efforts and offering practical implications for supporting students during the transition to employment.

Maternal and paternal attachment may relate differently to adolescent depressive symptoms, but the potential contribution of oxytocin receptor (OXTR) gene single nucleotide polymorphisms (SNPs) to these associations remains unclear. This six-month longitudinal study included 746 seventh- and tenth-grade students (50.7% female) from Guangzhou, China. Parent-child attachment and saliva samples for genotyping were collected at baseline, and depressive symptoms were assessed at follow-up using the CES-D-10. Overall, 48.8% of adolescents screened positive for depressive symptoms. Compared with adolescents below the cutoff, those who screened positive reported lower parental trust/communication and higher alienation (all p < 0.01). In adjusted linear regression models, father-child trust/communication was negatively associated with subsequent depressive symptoms (β = −0.26, p < 0.01), whereas mother-child alienation was positively associated with subsequent depressive symptoms (β = 0.15, p = 0.02). Exploratory moderation analyses showed a nominal rs2254295 × mother-child alienation interaction before correction (β = −0.07, p = 0.046), but this effect did not survive FDR correction. Father-child trust/communication and mother-child alienation showed distinct associations with adolescent depressive symptoms. The possible moderating role of OXTR rs2254295 should be regarded as preliminary and requires replication in larger independent samples.
