"Single-case experimental studies are particularly important for substantiating evidence for effective interventions or treatments. They have been used in a variety of disciplines, such as, education, counseling, psychology, psychiatry, neuroscience, medicine, social work, and sport sciences (Gustafson, Nassar, & Waddell, 2011; Kratochwill, 2015; Richards, Taylor, & Ramasamy, 2014). Yet such studies present unique methodological challenges to researchers and practitioners. Among these challenges are small sample sizes, naturally occurring trends, missing data, difficulty in meeting statistical assumptions, autocorrelation in the outcome measure, lack of a clear definition for population parameters, and the validity of visual analyses. This presentation will focus on three of these challenges, namely, visual analysis, trends, and missing data methods. Future research needs are identified and discussed."
