RESUMEN
Importance: Selecting effective antidepressants for the treatment of major depressive disorder (MDD) is an imprecise practice, with remission rates of about 30% at the initial treatment. Objective: To determine whether pharmacogenomic testing affects antidepressant medication selection and whether such testing leads to better clinical outcomes. Design, Setting, and Participants: A pragmatic, randomized clinical trial that compared treatment guided by pharmacogenomic testing vs usual care. Participants included 676 clinicians and 1944 patients. Participants were enrolled from 22 Department of Veterans Affairs medical centers from July 2017 through February 2021, with follow-up ending November 2021. Eligible patients were those with MDD who were initiating or switching treatment with a single antidepressant. Exclusion criteria included an active substance use disorder, mania, psychosis, or concurrent treatment with a specified list of medications. Interventions: Results from a commercial pharmacogenomic test were given to clinicians in the pharmacogenomic-guided group (n = 966). The comparison group received usual care and access to pharmacogenomic results after 24 weeks (n = 978). Main Outcomes and Measures: The co-primary outcomes were the proportion of prescriptions with a predicted drug-gene interaction written in the 30 days after randomization and remission of depressive symptoms as measured by the Patient Health Questionnaire-9 (PHQ-9) (remission was defined as PHQ-9 ≤ 5). Remission was analyzed as a repeated measure across 24 weeks by blinded raters. Results: Among 1944 patients who were randomized (mean age, 48 years; 491 women [25%]), 1541 (79%) completed the 24-week assessment. The estimated risks for receiving an antidepressant with none, moderate, and substantial drug-gene interactions for the pharmacogenomic-guided group were 59.3%, 30.0%, and 10.7% compared with 25.7%, 54.6%, and 19.7% in the usual care group. The pharmacogenomic-guided group was more likely to receive a medication with a lower potential drug-gene interaction for no drug-gene vs moderate/substantial interaction (odds ratio [OR], 4.32 [95% CI, 3.47 to 5.39]; P < .001) and no/moderate vs substantial interaction (OR, 2.08 [95% CI, 1.52 to 2.84]; P = .005) (P < .001 for overall comparison). Remission rates over 24 weeks were higher among patients whose care was guided by pharmacogenomic testing than those in usual care (OR, 1.28 [95% CI, 1.05 to 1.57]; P = .02; risk difference, 2.8% [95% CI, 0.6% to 5.1%]) but were not significantly higher at week 24 when 130 patients in the pharmacogenomic-guided group and 126 patients in the usual care group were in remission (estimated risk difference, 1.5% [95% CI, -2.4% to 5.3%]; P = .45). Conclusions and Relevance: Among patients with MDD, provision of pharmacogenomic testing for drug-gene interactions reduced prescription of medications with predicted drug-gene interactions compared with usual care. Provision of test results had small nonpersistent effects on symptom remission. Trial Registration: ClinicalTrials.gov Identifier: NCT03170362.

OBJECTIVE : Psychiatric hospitalizations and emergency department (ED) visits are costly, stigmatizing, and often ineffective. Given the immune and kynurenine activation in bipolar disorder (BD) and schizophrenia, as well as the immune-modulatory effects of statins, we aimed to compare the relative risk (RRs) of psychiatric hospitalizations and ED visits between individuals prescribed lipophilic vs. hydrophilic statins vs. no statins. We hypothesized (a) reduced rates of hospitalization and ER utilization with statins versus no statins and (b) differences in outcomes between statins, as lipophilia increases the capability to penetrate the blood-brain barrier with potentially beneficial neuroimmune, antioxidant, neuroprotective, neurotrophic, and endothelial stabilizing effects, and, in contrast, potentially detrimental decreases in brain cholesterol concentrations leading to serotoninergic dysfunction, changes in membrane lipid composition, thus affecting ion channels and receptors. METHODS : We used VA service utilization data from October 1, 2010 to September 30, 2015. The RRs for psychiatric hospitalization and ED visits, were estimated using robust Poisson regression analyses. The number of individuals analyzed was 683,129. RESULTS : Individuals with schizophrenia and BD who received prescriptions for either lipophilic or hydrophilic statins had a lower RR of psychiatric hospitalization or ED visits relative to nonstatin controls. Hydrophilic statins were significantly associated with lower RRs of psychiatric hospitalization but not of ED visits, compared to lipophilic statins. CONCLUSION : The reduction in psychiatric hospitalizations in statin users (vs. nonusers) should be interpreted cautiously, as it carries a high risk of confounding by indication. While the lower RR of psychiatric hospitalizations in hydrophilic statins relative to the lipophilic statins is relatively bias free, the finding bears replication in a specifically designed study. If replicated, important clinical implications for personalizing statin treatment in patients with mental illness, investigating add-on statins for improved therapeutic control, and mechanistic exploration for identifying new treatment targets are natural next steps.
RESUMEN
Adults with serious mental illness have high rates of obesity, with associated negative impacts on health-related quality of life. The present study utilized data from a randomized controlled trial (N = 276) to examine the effectiveness of in-person and online-delivered weight management interventions, compared to usual care, for improving health-related quality of life in this population. Participants completed quality of life assessments at baseline, 3 months, and 6 months. Mixed effects models examined group by time interactions. Compared to usual care, in-person MOVE was associated with improvements in loneliness (t = - 2.76, p = .006) and mental health related quality of life (t = 1.99, p = 0.048) at 6 months, and webMOVE was associated with improvements in weight-related self-esteem at 6 months (t = 2.23, p = .026) and mental health-related quality of life at 3 months (t = 2.17, p = 0.031) and 6 months (t = 2.38, p = .018). Web-based and in-person weight management led to improvements in health-related quality of life for adults with serious mental illness.ClinicalTrials.gov Identifier: NCT00983476.

BACKGROUND: People with psychosis struggle with decisions about their use of antipsychotics. They often want to reduce the dose or stop, while facing uncertainty regarding the effects these decisions will have on their treatment and recovery. They may also fear raising this issue with clinicians. The purpose of this study was to develop and test a shared decision making (SDM) tool to support patients and clinicians in making decisions about antipsychotics. METHODS: A diverse editorial research team developed an Encounter Decision Aid (EDA) for patients and clinicians to use as part of the psychiatric consultation. The EDA was tested using 24 semistructured interviews with participants representing six stakeholder groups: patients with first-episode psychosis, patients with long-term psychosis, family members, psychiatrists, mental health counselors, and administrators. We used inductive and deductive coding of interview transcripts to identify points to revise within three domains: general impression and purpose of the EDA; suggested changes to the content, wording, and appearance; and usability and potential contribution to the psychiatric consultation. RESULTS: An EDA was developed in an iterative process that yielded evidence-based answers to five frequently asked questions about antipsychotic medications. Patients with long-term psychosis and mental health counselors suggested more changes and revisions than patients with first-episode psychosis and psychiatrists. Family members suggested more revisions to the answers about potential risks of stopping or adjusting antipsychotics than other respondents. CONCLUSIONS: The EDA was perceived as potentially useful and feasible in psychiatric routine care, especially if presented during the consultation.

OBJECTIVE: The study was designed to explore patterns of prescriber communication behaviors as they relate to consumer satisfaction among a serious mental illness sample. METHODS: Recordings from 175 antipsychotic medication-monitoring appointments between veterans with psychiatric disorders and their prescribers were coded using the Roter Interaction Analysis System (RIAS) for communication behavioral patterns. RESULTS: The frequency of prescriber communication behaviors (i.e., facilitation, rapport, procedural, psychosocial, biomedical, and total utterances) did not reliably predict consumer satisfaction. The ratio of prescriber to consumer utterances did predict consumer satisfaction. CONCLUSIONS: Consistent with client-centered care theory, antipsychotic medication consumers were more satisfied with their encounters when their prescriber did not dominate the conversation. PRACTICE IMPLICATIONS: Therefore, one potential recommendation from these findings could be for medication prescribers to spend more of their time listening to, rather than speaking with, their SMI consumers.

BACKGROUND: People with serious mental illness have high rates of obesity and related medical problems, and die years prematurely, most commonly from cardiovascular disease. Specialized, in-person weight management interventions result in weight loss in efficacy trials with highly motivated patients. In usual care, patient enrollment and retention are low with these interventions, and effectiveness has been inconsistent. OBJECTIVE: To determine whether computerized provision of weight management with peer coaching is feasible to deliver, is acceptable to patients, and is more effective than in-person delivery or usual care. DESIGN: Mixed-methods randomized controlled trial. PARTICIPANTS: Two hundred seventy-six overweight patients with serious mental illness receiving care at a Veterans Administration medical center. INTERVENTIONS: Patients were randomized to 1) computerized weight management with peer coaching (WebMOVE), 2) in-person clinician-led weight services, or 3) usual care. Both active interventions offered the same educational content. MAIN MEASURES: Body mass index; and feasibility and acceptability of the intervention. KEY RESULTS: At 6 months, in obese patients (n = 200), there was a significant condition by visit effect (F = 4.02, p = 0.02). The WebMOVE group had an average estimated BMI change from baseline to 6 months of 34.9 ± 0.4 to 34.1 ± 0.4. This corresponds to 2.8 kg (6.2 lbs) weight loss (t = 3.2, p = 0.001). No significant change in BMI was seen with either in-person services (t = 0.10, p = 0.92), or usual care (t = -0.25, p = 0.80). The average percentage of modules completed in the WebMOVE group was 49% and in the in-person group was 41% (t = 1.4, p = 0.17). When non-obese patients were included in the analyses, there was a trend towards a condition by visit effect (F = 2.8, p = 0.06). WebMOVE was well received, while the acceptability of in-person services was mixed. CONCLUSIONS: Computerized weight management with peer support results in lower weight, and can have greater effectiveness than clinician-led in-person services. This intervention is well received, and could be feasible to disseminate.

BACKGROUND: Smartphones with programmable apps may offer innovative interactive interventions for improving adherence among people living with HIV with substance use problems. METHODS: This pilot randomized controlled trial sought to primarily determine the usability and feasibility of using a smartphone-based intervention called Heart2HAART as an adjunct to directly observed treatment with adherence counseling compared to directly observed treatment with adherence counseling alone among those with HIV and a history of substance use over a three-month time frame. Participants in the Heart2HAART condition completed an additional survey on usability and acceptability. Adherence was measured using unannounced pill counts assessed via a phone call. RESULTS: Twenty-eight participants were randomized to receive Heart2HAART (n = 19) or control (n = 9). All were receiving either weekly (n = 9) or daily (n = 19) observed treatment. Among those randomized to Heart2HAART, 63.2% reported no difficulty using the Heart2HAART smartphone application and 94.7% responded that the medication reminders did not interfere negatively with their activities. On average participants used Heart2HAART application 56.8 times over the three-month trial. In analyses adjusting for age, there was no difference in adherence to HAART medication between the Heart2HAART and control group as evaluated by the random pill count assessment (P = .29). CONCLUSIONS: Heart2HAART was feasible to use during a three-month pilot trial. Future studies may evaluate a more tailored approach, with more robust contingency management.

Adherence to recommendations for monitoring of metabolic side effects of antipsychotic medications has been historically low. This randomized controlled trial tested whether a computerized, patient-centered intervention that educated Veterans with serious mental illness about these side effects and encouraged them to advocate for receipt of monitoring would increase rates of monitoring compared to enhanced treatment as usual. The mean proportion of days adherent to monitoring guidelines over the 1-year study was similarly high and did not differ between the intervention (range 0.81-0.98) and comparison (range 0.76-0.96) groups. Many individuals in both groups had persistent abnormal metabolic parameter values despite high rates of monitoring, contact with medical providers, and receipt of cardiometabolic medications. Participants exposed to the intervention were interested in receiving personalized information about their cardiometabolic status, demonstrating the preliminary feasibility of brief interventions for enhancing involvement of individuals with serious mental illness in health care decision making.

This study sought to: (1) determine the prevalence of gambling disorder using the Diagnostic and Statistical Manual of Mental Disorders Version 5 (DSM-5; American Psychiatric Association in Diagnostic and statistical manual of mental disorders, American Psychiatric Publishing, Arlington, 2013) criteria; (2) identify the frequency and amount of money spent on gambling behaviors; and (3) determine demographic and treatment related predictors associated with gambling disorder in a substance using population. People receiving methadone maintenance treatment (N = 185) in an urban medical center consented to participate in the study. We used DSM-5 criteria to assess the 12-month prevalence of gambling disorder. Questions adapted from a previously developed measure were used to identify, describe and quantify the frequency of use and amount of money spent on gambling behaviors. Most participants were African-American (71.4 %), male (54.1 %), unmarried (76.8 %), unemployed (88.1 %) and had an income of <$20,000 (88.5 %). On average, participants were receiving 81.0 mg of methadone (SD: 22.8) daily. Nearly half (46.2 %) of participants met DSM-5 criteria for gambling disorder. Compared to those without gambling disorder, those with gambling disorder did not differ significantly with respect to demographic characteristics nor methadone dose. However, those with gambling disorder had been in methadone maintenance treatment for significantly less time. Those with gambling disorder were significantly more likely to report engaging in a variety of gambling behaviors. Given that the 12-month prevalence of DSM-5 defined gambling disorder was nearly 50 % future efforts to screen and treat gambling disorder in the context of methadone maintenance treatment are clearly warranted.

This study evaluated internet use among 239 veterans with serious mental illness who completed questionnaires assessing demographics and internet use in 2010-2011. The majority of individuals (70 %) reported having accessed the internet and among those, 79 % had accessed it within the previous 30 days. Those who were younger and more educated were more likely to have accessed the internet, as were those with a schizophrenia spectrum disorder, bipolar disorder, or major depressive disorder, compared to individuals with PTSD. Veterans with serious mental illness commonly use the internet, including to obtain health information, though use varies across demographic characteristics and clinical diagnosis.

BACKGROUND AND OBJECTIVES: The goal of this study was to determine the diagnostic accuracy of brief screens for Gambling Disorder within a sample of people receiving outpatient treatment for substance use disorders. METHODS: Individuals (n = 300) recruited from intensive outpatient substance use treatment (23.67%) or methadone maintenance programs (76.34%) participated in the study. Four brief screens for Gambling Disorder were administered and compared to DSM-5 criteria. Receiver operator curves were created and an Area Under the Curve (AUC) analysis (an overall summary of the utility of the scale to correctly identify Gambling Disorder) was assessed for each. RESULTS: On average participants were aged 46.4 years (SD = 10.2), African American/Black (70.7%), with an income less than $20,000/year (89.5%). Half the participants were female. Approximately 40% of participants (40.5%; n = 121) met DSM-5 criteria for Gambling Disorder. Accuracy of the brief screens as measured by hit rate were .88 for the BBGS, .77 for the Lie/Bet, .75 for NODS-PERC, and .73 for the NODS-CLiP. AUC analysis revealed that the NODS-PERC (AUC: .93 (95% CI: .91-.96)) and NODS-CLiP (AUC: .90 (95% CI: .86-.93)) had excellent accuracy. DISCUSSION AND CONCLUSIONS: The NODS-PERC and NODS-CLiP had excellent accuracy at all cut-off points. However, the BBGS appeared to have the best accuracy at its specified cut-off point. SCIENTIFIC SIGNIFICANCE: Commonly used brief screens for Gambling Disorder appear to be associated with good diagnostic accuracy when used in substance use treatment settings. The choice of which brief screen to use may best be decided by the needs of the clinical setting.

OBJECTIVE: Consumers with serious mental illness smoke more and are at higher risk for smoking-related illness. We examined provider and consumer factors influencing the implementation of the evidence-based "5 A's" (ask, advise, assess, assist, arrange) in six community mental health centers in greater Baltimore. METHODS: Data collected as part of a larger study examining the effectiveness of delivery of the 5 A's at patient visits. First, we examined responses to a survey administered to 49 clinicians on barriers and attitudes toward delivering the 5 A's. Second, we used multilevel models to examine variance between patients (n = 228), patient factors, and variance between their psychiatrists (n = 28) in the delivery of the 5 A's (and first 3 A's). RESULTS: The most strongly endorsed barrier was perceived lack of patient interest in smoking cessation. Psychiatrists and patients both accounted for significant variance in the delivery of the 5 A's and 3 A's. Patient "readiness to change" predicted delivery of the full 5 A's, while smoking severity predicted delivery of the first 3 A's. CONCLUSIONS: There is a critical need for creative and collaborative solutions, policies, and clinician training to address actual and perceived obstacles to the delivery of evidence-based smoking cessation treatment in the mental health care setting.

Tobacco smoking is highly prevalent in persons with psychosis and is the leading cause of preventable mortality in this population. Less is known about tobacco smoking in persons with first episode psychosis (FEP) and there have been no estimates about the prevalence of nicotine vaping in FEP. This study reports rates of tobacco smoking and nicotine vaping in young people with FEP enrolled in Coordinated Specialty Care programs in Pennsylvania and Maryland. Using data collected from 2021 to 2023, we examined lifetime and recent smoking and vaping and compared smokers and vapers to nonusers on symptoms, functioning, and substance use. The sample included 445 participants aged 13-35 with recent psychosis onset. Assessments were collected by program staff. Overall, 28 % of participants engaged in either smoking or vaping within 30 days of the admission assessment. Smokers and vapers were disproportionately male, cannabis users, and had lower negative symptom severity than non-smokers. Vapers had higher role and social functioning. Both smoking and vaping were related to a longer time from psychosis onset to program enrollment. We compare these findings to previous studies and suggest steps for addressing smoking and vaping in this vulnerable population.

OBJECTIVE: This study surveyed the use of anticholinergic medications (ACMs) in older Asian patients with schizophrenia and examined its demographic and clinical correlates. METHOD: A total of 1452 hospitalized patients with schizophrenia aged 55 years or older in nine Asian countries and territories were surveyed between 2001 and 2009. The cross-sectional data of patients' socio-demographic and clinical characteristics and the prescriptions of antipsychotic drugs and ACM were recorded using a standardized protocol and data collection procedure. RESULTS: The frequency of ACM prescription was 64.6% in the pooled sample, with 72.4%, 61.9%, and 59.5% in 2001, 2004, and 2009, respectively. Multiple logistic regression analysis of the whole sample revealed that patients on ACM had a higher dose of antipsychotic medications, and were more likely to have extrapyramidal side effects and receive first-generation antipsychotic medications. CONCLUSIONS: Anticholinergic medications were frequently used in older Asian patients with schizophrenia. Considering the potential side effects of ACM, the rationale for their widespread use in this patient population should be revisited.

OBJECTIVE: The aim of this study was to survey the use of antipsychotic polypharmacy (APP) in older Asian patients with schizophrenia and examine its demographic and clinical correlates. METHODS: Information on hospitalized patients with schizophrenia aged 55 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns study. Data on 1439 patients in 6 Asian countries and territories including China, Hong Kong, Japan, Korea, Singapore, and Taiwan were analyzed. Sociodemographic and clinical characteristics and antipsychotic prescriptions were recorded using a standardized protocol and data collection procedure. RESULTS: The frequency of APP prescription was 51.6% in the pooled sample with wide intercountry variations. Multiple logistic regression analysis of the whole sample showed that patients on APP had higher antipsychotic doses and also were more likely to receive first-generation antipsychotics. CONCLUSIONS: Use of APP was common in older Asian patients with schizophrenia. Given the limited evidence supporting its efficacy, the potentially severe side effects and high costs, APP should be used with caution in this population. The reasons for and outcomes of the use of APP in this patient population merit further exploration.

OBJECTIVE: This study surveyed the prescribing patterns of antipsychotic medications in Asian older schizophrenia patients with extrapyramidal side effects (EPS) during the period between 2001 and 2009. METHOD: Information on 848 hospitalized patients with schizophrenia aged 60 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001 - 2009). Data from those patients with reported EPS from 8 Asian countries and territories including China, Hong Kong, Japan, Korea, Singapore, Taiwan, India and Malaysia were analyzed. The cross-sectional data of sociodemographic and clinical characteristics and antipsychotic prescriptions were collected using a standardized protocol and data collection procedure. RESULTS: Of the 309/848 (36%) patients suffering from EPS, 210 patients (210/309; 68.0%) received at least one type of first generation antipsychotic (FGA), and 99 (99/309; 32.0%) received second generation antipsychotics (SGAs) only. Of SGAs prescribed in patients with EPS, risperidone was the most commonly used (100/309; 32.4%) followed by olanzapine (33/309; 10.7%) and quetiapine (25/309; 8.1%). CONCLUSIONS: FGAs were frequently used in Asian older schizophrenia patients with EPS. Considering the potential adverse effects of FGAs on existing EPS, the reasons for the frequent use of FGAs need to be urgently identified.

BACKGROUND: This study examined the use of low doses of antipsychotic medications (300 mg/day CPZeq or less) in older Asian patients with schizophrenia and its demographic and clinical correlates. METHODS: Information on hospitalized patients with schizophrenia, aged 55 years or older, was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001-2009). Data on 1,452 patients in eight Asian countries and territories including China, Hong Kong, Japan, Korea, Singapore, Taiwan, India, and Malaysia were analyzed. Sociodemographic and clinical characteristics and antipsychotic prescriptions were recorded using a standardized protocol and data collection procedure. RESULTS: The prescription frequency for low doses of antipsychotic medications was 40.9% in the pooled sample. Multiple logistic regression analysis of the whole sample showed that patients on low doses of antipsychotic medications were more likely to be female, have an older age, a shorter length of illness, and less positive symptoms. Of patients in the six countries and territories that participated in all the surveys between 2001 and 2009, those in Japan were less likely to receive low doses of antipsychotics. CONCLUSION: Low doses of antipsychotic medications were only applied in less than half of older Asian patients with schizophrenia.

OBJECTIVE: This study examined the prescribing patterns of several first- (FGAs) and second-generation antipsychotic (SGAs) medications administered to older Asian patients with schizophrenia during the period between 2001 and 2009. METHOD: Information on hospitalized patients with schizophrenia aged 65 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001-2009). There were no older patients in Thailand, therefore data on 467 patients in eight Asian countries and territories including China, Hong Kong SAR, India, Japan, Korea, Malaysia, Singapore, and Taiwan were analysed. Cross-sectional socio-demographic data, clinical characteristics and antipsychotic prescriptions were assessed using a standardized protocol and data collection procedure. RESULTS: Of the 467 patients, 192 patients (41.1%) received FGAs only, 166 (35.5%) received SGAs only and 109 (23.3%) received a combination of FGAs and SGAs. Of the FGAs, haloperidol was the most commonly used (31.3%; mean 9.4 ± 6.7 mg/day), followed by chlorpromazine (15.4%; mean 126.4 ± 156.4 mg/day) and sulpiride (6.6%; mean 375.0 ± 287.0 mg/day). Of the SGAs, risperidone was the most commonly used (31.5%; mean 4.5 ± 2.7 mg/day), followed by olanzapine (13.1%; mean 13.6 ± 6.5 mg/day), quetiapine (7.3%; mean 325.0 ± 237.3 mg/day) and aripiprazole (1.9%; mean 17.6 ± 7.7 mg/day). CONCLUSIONS: FGAs and higher doses of certain SGAs (risperidone, olanzapine and quetiapine) were still commonly dispensed to older Asian patients with schizophrenia. Considering older patients' reduced tolerability of potentially severe side effects associated with FGAs and higher doses of certain SGAs, continuing education and training addressing the rational use of antipsychotics in this population is clearly needed.

Inadequate self-management of chronic medical conditions like Type 2 diabetes may play a role in the poor health status of individuals with serious mental illnesses. We compared adherence to hypoglycemic medications and blood glucose control between 44 diabetes patients with a serious mental illness and 30 patients without a psychiatric illness. The two groups did not differ in their ability to manage a complex medication regimen as assessed by a performance-based measure of medication management capacity. However, significantly fewer patients with a mental illness self-reported nonadherence to their hypoglycemic regimens compared to those without a mental illness. Although individuals with mental illnesses also had better control of blood glucose, this metabolic parameter was not correlated with adherence to hypoglycemic medications in either patient group. The experience of managing a chronic mental illness may confer advantages to individuals with serious mental illnesses in the self-care of co-occurring medical conditions like Type 2 diabetes.

PURPOSE: The aim of the current study is to compare the predictors of health-related quality of life in individuals with schizophrenia, major mood disorder, and no mental illness, all with type 2 diabetes. METHODS: A total of 100 individuals with schizophrenia, 101 with a major mood disorder, and 99 without mental illness, all with type 2 diabetes, rated their health-related quality of life on the Medical Outcomes Survey, Short Form-12; physical and mental composite scores (PCS and MCS) were calculated. We performed a hierarchical multiple regression on PCS and MCS in each sample starting with a basic set of predictors and then adding diabetes-related variables. We compared the regression weights and incremental variance explained within each group. RESULTS: The number of co-occurring medical conditions was significantly associated with lower PCS in all three groups and with lower MCS in the no mental illness group. Diabetes-related variables added significant incremental variance to the prediction of PCS in the no mental illness group but not in either psychiatric group. CONCLUSIONS: For persons with diabetes and mental illness, as well as with no mental illness, additional medical conditions exert a strong effect on physical well-being. The impact on quality of life of diabetes-related factors may be lower in persons with diabetes and serious mental illness compared to those with diabetes and no mental illness.
