In the present study, using a relational efficacy framework, I examined the advisory working alliance and its associations with research self-efficacy among clinical and counseling psychology PhD students. Moreover, I examined whether the research training environment (RTE) and relation-inferred self-efficacy (RISE) mediated the relationship between the advisory working alliance and research self-efficacy. Finally, I examined whether other-efficacy moderated the relationship between RISE and research self-efficacy. Utilizing Qualtrics software, 144 PhD students from American Psychological Association-accredited clinical and counseling psychology programs completed questionnaires measuring the advisory working alliance, RTE, RISE, other efficacy, and research self-efficacy. Results from path analysis found that RISE mediated the relationship between the advisory working alliance and research self-efficacy. Although RTE did not mediate this relationship, the advisory alliance significantly and positively predicted student perceptions of the larger RTE. Moreover, other-efficacy moderated the relationship between RISE and research self-efficacy. It appears that the advisory working alliance transmits relationship-specific information to students that in turn fosters students' perceived research self-efficacy. However, the extent to which this relationship-specific information fosters research self-efficacy may depend in part on the extent to which students view their advisors as adept and competent researchers. Lastly, positive advisory alliances may play a key role in shaping students' perceptions of the larger RTE. Theoretical and training implications are discussed accordingly.
