This study examined social workers' perceived use of theories and methods in practice through a questionnaire completed by social workers in New York City (N=105) followed by individual interviews (N=20). Social workers received approximately one to six courses on theory in their education that moderately influenced their current practice. The most commonly used theories in practice included Cognitive Behavioral Therapy, Strengths Perspective, and Trauma-Informed Care. Social workers either applied theory to practice in an intentional and systematic way or indicated their "practice was not that intentional." Social work education was reported to provide a breadth but not depth of knowledge on theory. Recommendations for social work education to strengthen the link between theory and practice are provided.
