As the nation becomes more diverse, multicultural competence and social justice are being increasingly recognized as essential components to effective therapy practice (Hays, 2020; Ratts et al., 2016; Vera & Speight, 2003). While some scholars in the field of Couple and Family Therapy (CFT) have urged the importance of infusing social justice into training and clinical practice for years (see Hardy, 2001; Knudson-Martin et al., 2019; McDowell et al., 2019; McGoldrick, 2007), this topic is understudied and underprioritized by the field at large. Recent CFT scholars also acknowledge the importance of advocacy as an accompaniment to therapy (J. M. Goodman et al., 2018, Jordan & Seponski, 2018a, 2018b). Counseling and social work fields have prioritized social justice advocacy and codified it into mission statements and ethical codes (Ratts et al., 2016; Ratts & Greenleaf, 2018; Toporek & Daniels, 2018). Although CFTs are trained systemically, and may be enacting micro-level advocacy intervention in the therapy room, they do not always view themselves as advocates or enact macro-level advocacy interventions (J. M. Goodman et al., 2018; Holyoak et al., 2020; Jordan & Seponski, 2018b). This study utilized a sequential transformative mixed methods design to assess multicultural competence, social justice commitment and self-efficacy, and advocacy competence in a nationally representative sample of CFTs (n = 101) using survey methods. A subsample of 22 participants were interviewed to further explore their practices as multiculturally competent and socially just clinicians. Three complementary frameworks were utilized to ground the study: The Multicultural and Social Justice Counseling Competencies (MSJCC), critical consciousness, and Public Health Critical Race praxis. Overall, multicultural competence, social justice commitment, and social justice self-efficacy scores were high in this sample, while advocacy competence scores were lower. Results showed that identifying as Black or African American and completing additional training in multicultural competence and social justice were associated with multicultural competence. Results also showed that working in an agency setting vs. other settings was associated with lower levels of multicultural competence. Results showed that identifying as female compared to male, having a higher level of oppression, a higher level of civic engagement, and more additional training in multicultural competence were all associated with social justice commitment. Results showed that being older, completing more additional training, and having a higher level of oppression were all associated with higher levels of social justice self-efficacy. Finally, results showed that identifying as non-binary compared to male, completing more hours of additional training, and experiencing higher levels of oppression were all associated with advocacy competence. Additionally, receiving more post-graduate hours of training in multicultural competence, social justice, and advocacy competence was associated with higher multicultural competence, social justice, and advocacy competence. Qualitative findings revealed ways in which CFTs developed and embodied socially just clinical practice and explored recommendations for training.
