Trial Outcomes & Findings for Pilot Study of Cognitive Behavioral Therapy for Anxiety and Bipolar I Disorder (NCT NCT01892306)

NCT ID: NCT01892306

Last Updated: 2017-05-12

Results Overview

The Hamilton Anxiety Rating Scale (HAM-A) is a well-validated clinician administered rating of anxiety-related symptoms. Ratings are made on a 0 (no symptoms) to 4 (most severe in frequency/duration/interference/distress) for each item (14 items), with a minimum score of 0 and a maximum score of 56 calculated by summing scores of all 14 items. Higher scores indicate greater impairment.

Participant Flow

37 were invited to consent. 34 consented to be screened for inclusion. 5 did not meet study inclusion criteria thus were not randomized (1 not on a stabilized medication; 1 did not meet criteria for anxiety disorder; 2 were currently substance dependent; 1 reported psychosis). 29 were randomized to TAU or TAU plus 18 sessions of CBT (UP+TAU).

Participants were excluded from the trial before assignment to study arms based on exclusion criteria related to diagnosis and unstable medication regime.

PRIMARY outcome

Timeframe: Six months

Population: ITT analysis, data imputed to account for 30% missing data. A total of 28 people were included in the ITT analysis - one TAU participant initiated CBT through a private practitioner mid-study (an exclusion criteria) and was subsequently excluded from the analysis.

The Hamilton Depression Rating Scale (HAM-D) is a well-validated clinician administered rating of depression-related symptoms. Scores are calculated by summing scores across all 17-items, with a minimum score of 0 and a maximum score of 54. Higher scores indicate greater impairment.

The Client Satisfaction Questionnaire (CSQ) is an 8-item scale that assesses perceptions of acceptability and quality of outpatient treatment. Ratings are made on a 1 (poor) to 4 (excellent) scale for each item and then summed for a total score, with a minimum score of 8 and a maximum score of 32. Higher scores indicate greater satisfaction with treatment.

Emotion regulation skills were assessed using a measure of emotion regulation (Difficulties in Emotion Regulation Scale- DERS), a 36-item Likert-type scale (1-6) calculated by averaging scores across all items. See Baseline Characteristics for baseline DERS score. See Primary Outcome Measure for a description of HAM-A.

Neuroticism was assessed using the NEO Five Factor Inventory (NEO-FFI-N) which is a subscale of the NEO-FFI, a 60-item Likert-type scale (1-5) calculated by summing scores for each subscale. Only the 15-item Neuroticism subscale is included in this study. See Baseline Characteristics for baseline NEO-FFI-N. See Primary Outcome Measure for description of HAM-A.

Timeframe: Six Months

Population: Participating in the fMRI portion of the study was optional. A total of 15 participants consented to participate in fMRI portion (7 TAU+UP, 8 TAU). Data from all 15 subjects were analyzed.

Resting state functional magnetic resonance imaging (rsfMRI) data (non-task, eyes opened) was acquired to investigate anterior insula and ventrolateral prefrontal cortex functional connectivity as a predictor of change on depression (HAM-D). See primary outcome description of HAM-D.
