Note. Baseline values and social desirability were entered as covariates. Based on repeated measures MANCOVAs (and follow-up ANOVAs) using complete cases (Ns ranged from 194 for Self-monitored stress to 204 for most of the other measures). Means are not adjusted for baseline levels or covariates. * = p < .05; ** = p < .01; *** = p < .001; a = p < .1.
