Note: SEs are in parentheses. These means are based on analysis of covariance (ANCOVA) in which time 1 means for each outcome variable were used as the covariate in separate ANCOVAs. Covariates appearing in these ANCOVAs are evaluated at the following values: time 1 belonging = 5.406, time 1 threat = 4.247, time 1 threat/challenge ratio = 0.819, time 1 self-efficacy = 5.123, time 1 switching majors = 2.621, time 1 engineering advanced degree intentions = 5.552, and time 1 engineering career intentions = 6.284.
