Building on prior research (Cable, Gino, & Staats, 2013) showing that an orientation program that emphasizes authentic self-expression (ASE) may facilitate newcomer adjustment, the present longitudinal quasi-field experiment further tests the effects of the ASE program, with a focus on the dynamic treatment effects on socialization outcomes (i.e., perceived stress, popularity, and job performance). Participants were two cohorts of newly-hired nurses entering into a large hospital in China, with the first cohort receiving a traditional orientation and the second cohort receiving an ASE orientation. The final sample consists of two groups of 37 nurses, matched on various demographic variables. Participants were followed up four times (Months 3, 6, 9, and 12) post-entry. Results showed that compared with the control group, nurses in the ASE condition (a) reported a lower level of perceived stress at Month 3, and this effect was maintained over 12 months, (b) were rated by their peers as more popular and had better job performance ratings by their mentors at Month 12, with the treatment effect emerging over time. Further, perceived stress and rate of popularity change mediated the ASE effect on job performance at Month 12.
