The proposed, three phase project will refine and test a first-ever care approach in SSA that combines LAI with a behavioral program specifically intended to promote medication adherence in chronic psychotic disorders (CPDs). In addition to the novel focus, innovative elements include: 1.) a manualized curriculum that targets specific barriers and facilitators to medication adherence in Tanzanians with CPD, 2.) targeting known, high-risk individuals with CPD (those who miss ≥20% of prescribed antipsychotic medication, and 3.) using existing injection clinic health workers to deliver the adherence promotion program. Strengths include the highly generalizable methods and use of LAIs that are available in low-resource settings.

---|---|---|---|---|
Primary | Tablets Routine Questionnaire (TRQ) | The TRQ evaluates adherence to medications via a brief self-report instrument that has been validated in populations with bipolar disorder medication adherence. The TRQ identifies nonadherent individuals, defined as those who miss 20-30% or more of their medication in the last week or month. Total scores are represented as a percentage and range from 0 to 100, with higher scores indicating a greater level of nonadherence (higher scores indicate worse adherence to medications). | Change from Baseline to 6 month visit | |
Primary | Long-Acting Injectable Adherence (LAI Adherence): Count of Participants Who Received All LAI Injections: | LAI injection adherence will be determined as a count of participants who received LAI injections at the appropriate time (within 7 days of scheduled time). | Baseline to 6 month visit | |
Secondary | Drug Attitude Inventory (DAI) | 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. | Baseline to 6 month visit | |
Secondary | Brief Psychiatric Rating Scale (BPRS) | The BPRS measures levels of mania. There are 24 items, scored on a 7-point scale ranging from 0 to 6. Total scores range from 0 to 42, with higher scores indicating higher levels of mania. | Baseline to 6 month visit | |
Secondary | Clinical Global Impressions (CGI) | The minimum possible score is 1 and the maximum score is 7. A higher score implies a worse condition. | Baseline to 6 month visit | |
Secondary | Social and Occupational Functioning Scale (SOFAS) | 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 6 month visit | |
Secondary | Body Mass Index | Body Mass Index kg/m^2 of participants | Baseline to Month 6(week 25) | |
Secondary | ESRS-A Parkinsonism | Extrapyramidal Symptoms Scale-Abbreviated version for Parkinsonism. It looks at drug-induced Parkinsonism which is made up of motor disturbances. Rigidity, tremor, reduced facial expression/speech, impaired gait/posture, postural instability, and bradykinesia. Each item is rated on a 4 point scale: 0=absent, 3=severe. The higher the value the more severe the Parkinsonism and worst outcomes. | Baseline to 6 months(25 weeks) | |
Secondary | ESRS-A Dystonia | Extrapyramidal Symptoms Scale-Abbreviated version for dystonia- drug-induced dystonia is a muscle disorder in which movements are jerky or twisting. Due to the 0.00 values at baseline and 25 weeks, unable to perform t-test and get a p value so no statistical analysis section is reported for this Outcome Measure. Each item is rated on a 4 point scale: 0=absent, 3=severe with the higher numbers indicating worse dystonia and worse outcomes. | Baseline to 6 months(25 weeks) | |
Secondary | ESRS-A Dyskinesia | Extrapyramidal Symptoms Scale-Abbreviated version for Dyskinesia- drug-induced dyskinesia which is repetitive and involuntary movements. Each item is rated on a 4 point scale: 0=absent, 3=severe and higher values indicate greater severity of dyskinesia and worse outcomes. | Baseline to 6 months(25 weeks) | |
Secondary | ESRS-A Akathisia | Extrapyramidal Symptoms Scale-Abbreviated version for akathisia- drug-induced akathisia consists of inner restlessness and urge to move. Items are measured on a 4 value scale: 0=absent, 3=severe, and higher values indicate more severe akathisia and worse outcomes. | Baseline to 6 months(25 weeks) |
