In addition to the assessment of side effects, other scales will be used to measure side effects commonly associated with antipsychotic medications. Each month, a blinded research assistant will perform an Abnormal Involuntary Movement Scale (AIMS, to assess for tardive dyskinesia), Barnes Akathisia Scale, and Simpson-Angus Scale (to assess for dystonia and parkinsonian side effects). Movement disorders can affect the ability of patients to perform on cognitive tests and in skills training groups. Patients with akathisia often have reduced attention and reduced ability to concentrate in groups. Patients with parkinsonian symptoms can be slower on manual tasks and may have slower mental abilities.
