The purpose of this mixed methods sequential explanatory study was to explore factors contributing to college counselors' spiritual competency by obtaining quantitative results from surveying 199 current members of the American College Counseling Association (ACCA) and then following up with 32 purposefully selected respondents based on high and low spiritual competency scores to explore those results in more depth. In the first quantitative phase, training exposure explained 15% of the variance in professional exposure. And professional exposure explained 40% of the variance in spiritual competency. An unexpected result was that there was no significant relationship between training exposure and spiritual competence. In second qualitative phase, follow up interview questions were used to explore what aspects of participants' training program were barriers or strategies to integrating spiritual competencies into their current practice, what aspects of professional exposure contributed to current practice, and what motivated counselors to integrate spiritual competencies into their current practice. In response the following themes emerged: (1) the role of faculty; (2) the role of counselor training program structure; (3) the role of personal worldview; (4) the role of honoring the client's worldview; (5) the role of supervision, consultation, and practice; and (6) the role of client needs. The results of this study inform a deeper understanding of the relationship between college counselor background factors and current counseling practice with regards to religious and spiritual issues. Implications and recommendations for college counselors are provided. [The dissertation citations contained here are published with the permission of ProQuest LLC.
