Improving Outcomes for Individuals With Serious Mental Illness and Diabetes

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.

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.

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.

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.

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.

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.

Scores above 50 reflect higher functional status than the average population and scores below 50 reflect lower than average function.

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.

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.

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.

The ISMI (Internalized Stigma of Mental Illness) has 29 questions, broken into 5 subscales. This subscale, Alienation, has 6 Likert-scale items. Each question is rated as 1= strongly disagree, 2= disagree, 3= neutral, 4= agree, 5= strongly agree. Total scores on the Alienation subscale range from 6-30, with higher scores reflecting higher levels of reported internalized stigma of mental illness.

The ISMI (Internalized Stigma of Mental Illness) has 29 questions, broken into 5 subscales. This subscale, Stereotype Endorsement, has 7 Likert-scale items. Each question is rated as 1= strongly disagree, 2= disagree, 3= agree, 4= strongly agree. Total scores on the Stereotype Endorsement subscale range from 7-28, with higher scores reflecting higher levels of reported internalized stigma of mental illness.

The ISMI (Internalized Stigma of Mental Illness) has 29 questions, broken into 5 subscales. This subscale, Discrimination Experience, has 5 Likert-scale items. Each question is rated as 1= strongly disagree, 2= disagree, 3= neutral, 4= agree, 5= strongly agree. Total scores on the Discrimination Experience subscale range from 5-25, with higher scores reflecting higher levels of reported internalized stigma of mental illness.

The ISMI (Internalized Stigma of Mental Illness) has 29 questions, broken into 5 subscales. This subscale, Social Withdrawal, has 6 Likert-scale items. Each question is rated as 1= strongly disagree, 2= disagree, 3= neutral, 4= agree, 5= strongly agree. Total scores on the Social Withdrawal subscale range from 6-30, with higher scores reflecting higher levels of reported internalized stigma of mental illness.

The ISMI (Internalized Stigma of Mental Illness) has 29 questions, broken into 5 subscales. This subscale, Stigma Resistance, has 5 Likert-scale items. Each question is rated as 0= strongly disagree, 1= disagree, 2= neutral, 3= agree, 4= strongly agree. These scores are all reverse coded. Total scores on the Stigma Resistance subscale range from 0-20, with higher scores reflecting higher levels of reported internalized stigma of mental illness.

The Utilization of Physical Education score looks at how many times a participant used these resources. Analyses include a simple mean and SD.

The Utilization of Mental Education score looks at how many times a participant used these resources. Analyses include a simple mean and SD.

The Utilization of Mental Hospital score looks at how many times a participant used these resources. Analyses include a simple mean and SD.

The diabetes knowledge score has 23 questions which assess how much knowledge one has about diabetes. They are in multiple choice format, with 4 choices, and only one is correct. The total amount correct is added up, and then calculated into a percentage of answers correct.

The Multidimensional Scale of Perceived Social Support is a 12 question Likert scale, with each item ranging from 1-5. Total scores range from 12-60, with higher scores indicating more perceived social support.

The Perceived Diabetes Self-Management Scale is an 8-item Likert scale, with each question ranging from 1-5. Items 1, 2, 6, and 7 are reverse coded. Total summed scores range from 8-40, with higher scores indicating higher perceived self-management competence in regards to diabetes.

The Perceived Mental Health Self-Management Scale is an 8-item Likert scale, with each question ranging from 1-5. Total summed scores range from 8-40, with higher scores indicating higher perceived self-management competence in regards to mental health.
