Andrew J. Freeman is an assistant professor of psychology and director of the Development of Irritability Mood and Emotions Laboratory. Freeman teaches graduate level courses in Assessment of Children and supervises graduate students providing therapy services to children and adolescents at UNLV’s the PRACTICE.

Freeman’s research interest is primarily focused on irritability as a link between disruptive behavior disorders (e.g., oppositional defiance) and mood disorders (e.g., depression). Irritability is a normal emotion that occurs when we try to accomplish goals and are frustrated. Maladaptive irritability is a common symptom or associated feature of most types of psychopathology. Irritability is the primary reason why many individuals seek mental health services. Irritability is poorly understood and new classification systems created a disorder specific to irritability. In doing so, irritability was moved from being primarily a disruptive behavior disorder to a mood disorder. Therefore, his research examines the underlying etiology of irritability, best methods for assessing clinically significant irritability, and treatment of irritability in children and adolescents.

In addition, Freeman has served as a consultant for statistical services and to organizations regarding the implementation of evidence-based practice. He is a published author in evidence-based assessment. Evidence-based assessment examines methods for making clinical decisions about an individual regarding prediction (accurate diagnosis), prognosis (course of illness), and process (therapeutic process).
