Having a reliable and valid self-care measure for mental health professionals is the first step to analyzing the long-term implications of self-care. We suggest researchers fully utilize the existing measures or information and continue to assess and improve the psychometric properties of these scales. Moreover, training program faculty may consider tracking self-care development and its relations to professional outcomes longitudinally, both within the course of training and beyond. The professional organization may also consider incorporating self-care assessment into continuous education or professional development programs for independent and experienced professionals.

Based on the results of our review, we identified several self-care instruments for psychologists or psychology trainees with moderate to strong evidence for most of the measurement properties however, researchers should keep in mind that further evidence to support the use of these scales is needed. :

• Specifically, if the focus is on self-care behaviors at the individual level, we recommend the use of PSCS (designed for psychologists, Dorociak et al., 2017) and SCBI (designed for graduate trainees, Santana et al., 2017).

• If systems-level factors are considered, suggested measures include the PSEQ (designed for graduate trainees, Goncher et al., 2013) and TISC-Revised (designed for child welfare workers, Salloum et al., 2018).

• We also recommend the inclusion of a variety of validity measures (e.g., competence, professional functioning, and well-being) in assessment.
