Trial Outcomes & Findings for Research Study of Bipolar Mood Symptoms and Cognitive Problems (NCT NCT00428298)

NCT ID: NCT00428298

Last Updated: 2017-04-11

Results Overview

The RBANS is a brief, independently administered measurement of cognitive decline or improvement. The test is comprised of 12 subtests which comprise 5 domains. The age of the participant and the scores from each domain inform the total RBANS score (Index Score) analyzed in this study. The range for total score is 40-160. If the total score for a subject increases this denotes improved performance on the RBANS. The RBANS was administered at baseline and 16 weeks.

PRIMARY outcome

Timeframe: 16 weeks

Population: Participants who completed screening/first visit Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and study completion/last visit RBANS. Discrepancies in number of participants analyzed are due to subjects who dropped out and did not have final RBANS scores. Imputed data was used for those participants.

SECONDARY outcome

Timeframe: 16 weeks

Population: Discrepancies in number of participants analyzed are due to subjects who dropped out and did not have final assessments. Imputed data was used for those participants.

The MADRS is a 10 item depression rating scale administered by a research team member. The MADRS is composed of 10 items with a 7 point fixed rating scale (0-6). A higher score indicates the presence of depressive symptoms.

OTHER_PRE_SPECIFIED outcome

Timeframe: 16 weeks

Population: Discrepancies in number of participants analyzed are due to subjects who dropped out and did not have final assessments. Imputed data was used for those participants.

The Young Mania Rating Scale has 11 items that rate the subject's subjective experience and clinician observation. Four items are rated 0-8, the remaining are rated 0-4. The score can range from 0 to 60. A higher score indicates the presence of manic symptoms.
