The assessment of 361 youths with bipolar disorder reveal that irritable-only subgroups constitute 10 percent of this sample while elated-only subgroups constitute 15 percent of the sample. These findings support continued consideration for episodic irritability in the diagnosis of pediatric bipolar disorder.

The behaviours of infants were observed using home videos, in an attempt to identify social difficulties characteristic of infants with autistic disorder.

The definition of mental disorder in the third edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-III-R) explains that a disorder is harmful and represents a dysfunction, but it fails to capture the idea of dysfunction.

The Autism Behavior Checklist was evaluated with 94 autistic and 63 nonautistic subjects. Although the two groups differed significantly in ratings of pathology both false positive and false negative diagnostic classifications occurred.

Individuals with developmental disability (n=400) were assessed with the "Dyskinesia Identification System: Condensed User Scale" (DISCUS), a 15-item tardive dyskinesia rating scale shortened from the "Dyskinesia Identification System-Coldwater." Based on interrater reliability, 2-week stability, and other analyses, DISCUS is…

A self-report measure for the Type A subcomponent of time urgency and perpetual activation (TUPA) was developed using 10 coronary heart disease (CHD) patients and validated with another 48 CHD patients. The internal consistency and test-retest reliabilities indicate that the instrument has clinical and research applications. (SLD)
