This project tests a model for improving illness self-management among persons who have both serious mental illness and diabetes and will be performed within a primary care setting at a safety net hospital system. The information gained from the randomized trial will be supplemented with reports from participants about their experiences of trying to improve illness self-management. Improvements in self-management should result in a reduction of psychiatric symptoms and improvements in functioning and physical health.
This project will test a novel intervention, Targeted Training in Illness Management (TTIM), intended to improve both serious mental illness (SMI) and diabetes mellitus (DM) self-management in 100 individuals with SMI-DM vs. 100 individuals with SMI-DM receiving treatment as usual (TAU). The intervention will be conducted in a safety-net health system primary care setting and will be conducted as a randomized controlled trial (RCT). The primary effects of TTIM will be assessed with respect to SMI symptoms, Functional Status/Role Impairment, General Health Status, and DM outcomes. Secondary outcomes include adherence to psychotropic and DM medication, and engagement in healthy behaviors. This assessment will include quantitative assessment of facilitators/barriers targeted by the proposed intervention as well as a supplemental qualitative assessment. The qualitative assessments will include input from patients and interventionists. Specific aims for the qualitative analysis are to validate findings from the RCT, expand understanding of "key active ingredients" of TTIM, and provide information to inform future studies on individuals with SMI and related medical conditions.

This intervention blends psychoeducation, problem identification/goal-setting, behavioral modeling and reinforcement via use of Peer Educators, and health care linkage, has been adapted to the primary care setting and targeted for SMI-DM participants. Generalizability is enhanced with relatively brief in-person participation requirements and by utilizing professional staff typically found in primary care. TTIM will stress information sharing that is accessible to participants, and through a collaborative process, foster motivation for SMI-DM self-management.

Brief Psychiatric Rating Scale (BPRS) at 60 Weeks
The BPRS measures psychotic and non-psychotic symptoms in serious mental illness. Possible total scores range from 7 to 126, with higher scores indicating greater symptom severity. For this study, the BPRS with 18 items was used. Each symptom measured ranges from 1-7, and all 18 items/symptoms are summed to create the total score. Only the BPRS total score was utilized in the analyses.
Time frame: 60 weeks
Montgomery Asberg Depression Rating Scale (MADRS) at 60 Weeks
The MADRS is a 10-item depression severity scale widely utilized in studies with patients with serious mental illness. Possible scores range from 0 to 60 with higher scores indicating worse depression.
Time frame: 60 weeks
Clinical Global Impression (CGI) at 60 Weeks
The Clinical Global Impression (CGI) is a broad measure of global psychopathology that evaluates illness severity on a 1 to 7 point continuum. Possible scores range from 0 to 7, with higher scores indicating greater psychopathology.
Time frame: 60 weeks
Global Assessment of Functioning (GAF) at 60 Weeks
The GAF is a 100-point single-item scale that measures global functioning. Possible scores range from 1 to 100, with higher scores indicating better functioning.
Time frame: 60 weeks
Sheehan Disability Scale (SDS) at 60 Weeks
The SDS measures role impairment in three domains (work/school; family life/home; social life). Possible total scores range from 0 to 30, with higher scores indicating greater disability. Only the total score was reported in our analyses, and is denoted here. The total score is calculated by summing the three domain scores, each which range from 0-10.

SF-36 (Short-form) Health Survey at 60 Weeks; Mental Health Component
The Short Form 36 Health Survey (SF-36) is a self-report of general health divided into a physical component summary (PCS) and mental component summary (MCS). Norm-based scores are placed on the same metric with a mean of 50 and standard deviation of 10. Scores above 50 reflect higher functional status than the average population and scores below 50 reflect lower than average function.

Tablets Routine Questionnaire (TRQ) at 60 Weeks
The self-reported Tablets Routine Questionnaire (TRQ) measures change in treatment adherence. The TRQ determines proportion of prescribed medication missed, and ranges from 0 (no medication missed/100% adherent) to 100 (no medication taken/0% adherent). The TRQ format captured an exact proportion (%) of days with a missed medication dose for each oral maintenance psychotropic medication and then an average combined TRQ was calculated for all orally-prescribed medications.
Time frame: 60 weeks
Self-rated Diabetes Self-Care Activities (SDSCA) Questionnaire at 60 Weeks
The SDSCA measure is a brief self-report questionnaire of diabetes self-management that includes items assessing the following aspects of the diabetes regimen: general diet, specific diet, exercise, blood-glucose testing, foot care, and smoking. It is comprised of 10 questions, to which each have a 5 point scale with anchors 1= never through 5= always. The items are summed to a total score, which ranges from 10-50.

Comparison of AUDIT (Alcohol Use Disorders Identification Test) Score Between TTIM and TAU (Treatment as Usual) at 60 Weeks
The AUDIT scale (Alcohol Use Disorders Identification Test) has 10 questions, with scores on each question ranging from 0 to 4 (0= never, 1= less than monthly, 2= monthly, 3= weekly 4= daily/almost daily). Questions 9 and 10 only have three anchors: 0, 2, and 4. The scores are summed to get total. Therefore, the range of possible scores are 0-40, with higher scores indicating indicating a greater likelihood of hazardous and harmful drinking. However, such scores may also reflect greater severity of alcohol problems and dependence, as well as a greater need for more intensive treatment.
