His Master of Arts research project (Diener & Hilsenroth 2004) examined the validity of an empirically derived personality factor from the Shedler-Westen Assessment Procedure. For his dissertation, he conducted a meta-analysis on the association between therapist focus on patient affect and treatment outcomes in psychodynamic therapy (Diener, Hilsenroth, & Weinberger 2007).
Marc Diener worked as an assistant professor in the clinical psychology doctoral program at the American School of Professional Psychology, Washington DC, from 2007 until 2012. Beginning in 2012, he was an assistant professor in the clinical psychology doctoral program at Long Island University—Post, subsequently becoming tenured as an associate professor in 2016. He has authored 16 peer-reviewed articles and nine book chapters/other publications. From 2013 until 2015, he served as a consulting editor for Journal of Personality Assessment. He is currently a consulting editor for Psychotherapy, Journal of Psychotherapy Integration, and Journal of Contemporary Psychotherapy. In 2015, he became a fellow in the Division of Independent Practice of the American Psychological Association.
Marc Diener’s program of research examines personality assessment, psychotherapy process, and psychotherapy outcome. His publications have focused on self-report and performance-based measures of personality (e.g., Diener & Hilsenroth 2004; Diener et al. 2011) attachment (e.g., Diener & Monroe 2011; Diener et al. 2009; Diener et al. 2013; Diener et al. 2016) psychotherapy technique (e.g., Diener & Hilsenroth 2009; Diener & Mesrie 2015; Diener & Pierson 2013; Diener et al. 2007) psychotherapy outcome (e.g., Diener & Hilsenroth 2009; Diener & Pierson 2013; Diener et al. 2007), and application of meta-analytic methodology (e.g., Diener & Monroe 2011; Diener et al. 2007; Diener et al. 2009; Diener et al. 2011; Diener et al. 2013; Diener et al. 2016).
