CAE Plus LAI in Individuals With Bipolar Disorder at Risk for Treatment Non-adherence (BD-CAEL)

Study Overview
=================
Brief Summary
-----------------
This is a prospective study using customized adherence enhancement (CAE) and long-acting injectable (LAI) antipsychotic in 30 individuals with bipolar disorder (BD) at risk for treatment non-adherence. The CAE approach is expected to improve treatment adherence, as well as improve BD symptoms, functioning and treatment attitudes among subjects with bipolar disorder.

Detailed Description
-----------------
Oral Abilify (aripiprazole) is effective in the treatment of patients with BD when prescribed as an acute anti-manic agent and for the maintenance treatment of bipolar disorder. Abilify Maintena is an intramuscular (IM) depot formulation of oral aripiprazole (Abilify). Abilify Maintena appears to be as effective as standard oral Abilify and may maximize patient adherence. Recent clinical trials suggest that Abilify Maintena is effective for the treatment of patients with BD. Customized Adherence Enhancement (CAE) is a brief behavioral intervention that improves adherence approximately 30% more than an educational control in adults with BD. The CAE program is a brief, practical intervention consisting of a series of up to four psychosocial treatment modules based upon an adult's unique adherence barriers: 1) Psychoeducation on BD Medications; 2) Communication with Providers; 3) Strategies to Enhance Medication Routines; and 4) Targeting Substance Use Problems with Modified Motivational Enhancement Therapy. Multiple studies conducted by these investigators has shown that CAE is effective in in treating poorly adherent BD adults. In addition, studies by these investigators have shown that combining LAI + CAE dramatically improves adherence, symptoms and functional outcomes in people with schizophrenia and schizoaffective disorder. In summary, LAI can maximize medication adherence, while CAE addresses individual barriers to sustained adherence and behavioral change. Combining LAI + CAE improves adherence, symptoms and functioning in high-risk people with primary psychotic disorders. The proposed project will test the efficacy of combining Abilify Maintena with CAE to help improve outcomes in poorly adherent patients with BD. Pilot data suggest that adherence with concomitantly prescribed psychotropic drugs improves with LAI + CAE. The findings have particular relevance to BD because many BD patients are on concomitant oral psychotropic drugs in addition to antipsychotic. Thus, it is expected that combining CAE with LAI will lead to a halo effect in that these BD patients will engage in their own care more broadly.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patient Noncompliance<br>Subjects enrolled in the study will receive both Abilify Miantena and the Customized Adherence Enhancement (CAE) intervention | Drug: Abilify Maintena<br>* Drug is in an injectable form and will be administered approximately every four weeks through Week 24 of the study. Dosage is per package insert or at the discretion of the psychiatrist.<br>Behavioral: Customized Adherence Enhancement (CAE)<br>* CAE targets key areas relevant to non-adherent populations with schizophrenia or schizoaffective disorder: 1) inadequate or incorrect understanding of mental disorder; 2) lack of medication-taking routines; 3) poor communication with care providers; and 4) substance use which interferes with adherence and healthy behaviors that promote recovery. CAE is delivered based upon initial assessment of reasons for non-adherence and only those components of CAE that are determined to be indicated for that individual are delivered (psychoeducation, modified motivational interviewing, assistance with medication routines, coaching in communication with providers).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Tablets Routine Questionnaire (TRQ, Past Week) | Treatment non-adherence is measured as a percentage of medications not taken within the past week at time of assessment. The minimum score is 0% and the maximum score is 100%. A higher score implies poorer treatment adherence. | Screen to Week 24 | 
| Change in Tablets Routine Questionnaire (TRQ, Past Month) | Treatment non-adherence is measured as a percentage of medications not taken within the past month at time of assessment. The minimum score is 0 and the maximum score is 100. A higher score implies poorer treatment adherence. | Screen to Week 24 | 
| LAI Injection Adherence | LAI injection adherence will be determined as a proportion of LAI injections received at the appropriate time (within 7 days of scheduled time). | Baseline to Week 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Brief Psychiatric Rating Scale (BPRS) Score | The BPRS measure psychiatric symptoms such as depression, anxiety, hallucinations and unusual behavior. The minimum score is 18 and the maximum score is 126. A higher score implies a worse condition. | Baseline to Week 24 | 
| Change in Young Mania Rating Scale (YMRS) Score | The YMRS measures symptoms of mania. The minimum possible score is 0 and the maximum score is 60. A higher score implies a worse condition. | Screen to Week 24 | 
| Change in Montgomery Asberg Rating Scale (MADRS) Score | The MADRS measures symptoms of depression. The minimum possible score is 0 and the maximum score is 60. A higher score implies a worse condition. | Screen to Week 24 | 
| Change in Clinical Global Impressions (CGI) Score | The minimum possible score is 1 and the maximum score is 7. A higher score implies a worse condition. | Screen to Week 24 | 
| Change in Drug Attitude Inventory (DAI) Score | DAI-10 scoring ranges from -10 to +10 with a total score >0 indicating a positive attitude toward psychiatric medications and a total score of <0 indicating a negative attitude toward psychiatric medications | Screen to Week 24 | 
| Change in Attitude Towards Medication Questionnaire (AMSQ) Score | A modification of the Lithium Attitudes Questionnaire (Harvey 1991) which evaluates an individual's attitudes towards mood stabilizers. The AMSQ is used to measure attitudes towards medications. The scale contains 19 items grouped into 7 subscales: general opposition to prophylaxis (4 items), denial of therapeutic effectiveness (2 items), fear of side effects (2 items), difficulty with medication routines (4 items), denial of illness severity (3 items), negative attitudes toward drugs in general (3 items), and lack of information about psychiatric medication (1 item). Responses which suggest positive attitudes towards medications are scored 0, while responses which suggest negative attitudes towards medications are scored 1. The items scores are added for a total score which is reported, with the minimum total score of 0 and maximum total score of 19. Higher scores on each subscale represent more negative attitudes toward mood stabilizers. | Screen to Week 24 | 
| Change in Social and Occupational Functioning Assessment Scale (SOFAS) Score | The SOFAS measures social and occupational functioning independent of the overall severity of the individual's psychological symptoms. The minimum score is 0 and the maximum score is 100. A higher rating implies a higher level of functioning. | Baseline to Week 24 | 
| Change in Global Assessment of Functioning (GAF) Score | The minimum score is 1 and the maximum score is 100. A higher score implies higher functioning. | Baseline to Week 24 | 
| Change in Oxford Bipolar Knowledge Questionnaires (OBQ) Score | The OBQ assess knowledge of BD management. Total score rangers from 0-80, with a higher score indicative of better knowledge of bipolar mood management. | Screen to Week 24 | 
| Change in The Self-Report Habit Index (SRHI) Score | The SRHI is a measure of habit strength. The minimum score is 12 and the maximum score is 84. A higher score implies stronger habits. | Screen to Week 24 | 
| Change in Communication Styles Scale Score | The Communication Styles Scale is a measure of the impact of physician communication style on medication beliefs and adherence behavior. Total scores range from 0-27 where the higher score indicates a more initial collaborative communication style. | Screen to Week 24 | 
| Change in Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES 8A) Score | The SOCRATES measures motivation to reduce the use of substances. The minimum score is 10 and the maximum score is 50. A higher score indicates a higher desire to reduce drinking. | Screen to Week 24 |
