Descriptive Longitudinal Analysis of Stereotypy and Corresponding Changes in Psychotropic Medication.

Introduction: Psychotropic medication is often prescribed to individuals with intellectual and developmental disabilities who engage in challenging and other behavior (e.g., aggression and stereotypy, respectively), but there is limited understanding of the effects of these medications on behavior.

Characterizing Mood States in Individuals Diagnosed with Bipolar Disorder and Intellectual Disability.

Introduction: The purpose of this study was to gain additional insight on patterns of behavior of three individuals dually diagnosed with Intellectual disability (ID) and Bipolar disorder as they cycled between elevated and depressed mood states.

Methods: Data were collected from weekly, one hour observations across a period of several months. The total duration of time spent engaged in target responses (pacing, rocking, and talking), in addition to indirect measures of activity (irritability and hyperactivity subscale of the Aberrant Behavior Checklist-Community; ABC-C), were assessed to characterize and monitor changes in overall state.
