The present study examined the relationship between adult attachment and subjective social status (SSS) in college students through a cross-sectional survey (Study 1) and a longitudinal study (Study 2). In Study 1, 1300 college students were recruited via research flyers and online campus advertisements. They completed measures of adult attachment and SSS. The results showed that higher attachment anxiety and avoidance negatively predicted SSS. In Study 2, 958 freshmen students were recruited via the Freshmen Entrance Ceremony and underwent assessment four times (T1, T2, T3, and T4) at monthly intervals. The latent growth model results showed a significant decline in SSS during the first month of campus life, followed by a slow increase over the subsequent 2 months. While attachment avoidance did not predict a decline in SSS, attachment anxiety positively predicted the rate of decline in SSS, which meant that the higher the attachment anxiety was, the slower the rate of decline in SSS. Both studies indicated that both dimensions of attachment influence freshmen's SSS and that only attachment anxiety plays a role in the dynamics of SSS.
