An examination of predisposing and enabling factors that predict dental utilization among individuals with serious mental illness in Detroit, Michigan.

OBJECTIVES: This study evaluated which predisposing and enabling factors prospectively predicted dental utilization over 6 months among people with serious mental illness. METHODS: A sample of individuals with serious mental illness (86.3% African American; 97.4% with public health insurance) was recruited from community mental health centres in Detroit, Michigan, and responded to questionnaires at baseline and at least one follow-up visit at 3 or 6 months (N = 190). Baseline assessments included demographic and clinical information, established measures of health literacy, health insurance literacy, stigma related to mental illness, experiences of racial discrimination and medical mistrust. Insurance coverage for dental care and the availability of dental services at the participants' mental health centres was recorded. At follow-up visits, participants reported healthcare utilization, including dental and primary care, since baseline. RESULTS: Three factors emerged as meaningful predictors of having a dental visit in bivariate and multivariate analyses: more medical comorbidities and dental care co-located with mental health care predicted increased likelihood of a dental visit, whereas having experienced racial discrimination in a medical setting predicted lower odds of having a dental visit in the follow-up period. Co-location of dental care with mental health care was the strongest predictor of having a dental visit. CONCLUSIONS: Co-locating dental care with mental health care may increase dental utilization among people with serious mental illness, possibly by mitigating known barriers to dental care for this population. Among African Americans, the co-location of dental care with mental health care may also attenuate the negative effect of prior racial discrimination in a medical setting on dental utilization.

Treating pain in primary care: Optimizing an integrated psychological intervention based on perspectives of psychologists, primary care providers, and patients.

INTRODUCTION: Although behavioral health treatment can improve distress and pain functioning for patients with chronic pain, few who are referred by their primary care physician will see a behavioral health specialist. Given the benefits of integrating behavioral health into primary care, this may be an avenue for delivering a psychological intervention for chronic pain. The purpose of this study was to optimize a psychological intervention for patients with chronic pain to be delivered in primary care, utilizing the perspectives of providers and patients. METHOD: Psychologists (n = 9), primary care providers (n = 9), and patients with chronic pain (n = 9) participated in separate focus groups. Participants reviewed the proposed 4-session intervention, provided feedback prompted by a set of open-ended questions, and completed a survey. RESULTS: Statements from focus groups were transcribed and coded into 2 thematic categories: (a) content of the intervention and (b) logistics and design. Participants believed that offering a brief, behavioral intervention for chronic pain in a primary care clinic was feasible and useful. All providers (100%) agreed or strongly agreed that they would refer a patient to this intervention, and 100% of patients agreed or strongly agreed that they would participate. DISCUSSION: Feedback solicited from the focus groups led to alterations to the treatment manual, such as adding a fifth session, using different psychological strategies, and logistical changes in delivery (i.e., meeting biweekly and intervisit contacts). The modified version of this intervention will be evaluated with a pilot randomized controlled clinical trial. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

A New Measure of Health Numeracy: Brief Medical Numbers Test (BMNT).

BACKGROUND: Approximately half of Americans have inadequate health literacy, which leads to poorer health outcomes. Health numeracy is an important component of literacy, which reflects one's ability to understand and manipulate numbers. This is especially important for transplant candidates, as adherence to medical recommendations is essential for posttransplant care. Although validated measures of numeracy exist, they can be inconvenient and time consuming to administer. OBJECTIVE: The Brief Medical Numbers Test (BMNT) was created in 2011 to quickly assess the health numeracy of a patient during presurgical psychiatric transplant evaluations. The purpose of this study was to evaluate the reliability and validity of the BMNT for this use via retrospective chart review. METHODS: There were 293 patients referred over a 2-year period for a presurgical psychiatric evaluation. The evaluation consisted of a semistructured interview and completion of several measures, including the BMNT, a measure of health literacy, and a brief test of cognitive functioning. RESULTS: The BMNT had acceptable internal consistency (α = .71), convergent validity with health literacy and cognitive functioning, and predictive validity with surgical outcomes. CONCLUSIONS: Preliminary data suggests the BMNT is a reliable and valid measure of health numeracy in patients being evaluated for transplant.

Problematic Eating Behaviors Predict Outcomes After Bariatric Surgery.

BACKGROUND: There are no clear psychosocial predictors of weight loss following bariatric surgery. The purpose of this study was to investigate whether preoperative problematic eating behaviors predict weight loss outcomes following bariatric surgery. METHODS: Clinical records were utilized to examine outcomes of 101 patients who completed a pre-surgical psychosocial evaluation and underwent gastric bypass or sleeve gastrectomy. Information analyzed included binge eating history and scores from the Hospital Anxiety and Depression Scale, Yale Food Addiction Scale, and Emotional Eating Scale. Measures of weight loss 1 year post-surgery were compared to pre-surgical assessments. RESULTS: One-year follow-up data were available for 60 patients. Patients with higher levels of eating in response to anger/frustration (p = .02), anxiety (p = .01), or depression (p = .05) were more likely to miss the 1-year follow-up appointment. Eating in response to anger/frustration and depression were related to poorer weight loss outcomes. There was a trend for binge eating to predict greater %EWL (p = .06). A higher number of food addiction symptoms increased the likelihood that patients would experience less weight loss (p = .01). Psychiatric symptoms were not related to weight loss outcomes. CONCLUSIONS: Patients who endorsed higher levels of pre-surgical emotional eating and food addiction symptoms had poorer weight loss 1 year post-surgery. Providers should consider screening patients for these behaviors during the pre-surgical psychosocial evaluation which would allow opportunities for psychotherapy and potential improvement in weight loss outcomes. Future research should examine which interventions are successful at improving problematic eating behaviors.

Endogenous Opioid Mechanisms Are Implicated in Obesity and Weight Loss in Humans.

CONTEXT: Successful long-term weight loss is challenging. Brain endogenous opioid systems regulate associated processes; however, their role in the maintenance of weight loss has not been adequately explored in humans. OBJECTIVE: In a preliminary study, the objective was to assess central µ-opioid receptor (MOR) system involvement in eating behaviors and their relationship to long-term maintenance of weight loss. DESIGN: This was a case-control study with follow-up of the treatment group at 1 year after intervention. SETTING: The study was conducted at a tertiary care university medical center. PARTICIPANTS: Lean healthy (n = 7) and chronically obese (n = 7) men matched for age and ethnicity participated in the study. INTERVENTIONS: MOR availability measures were acquired with positron emission tomography and [(11)C]carfentanil. Lean healthy men were scanned twice under both fasted and fed conditions. Obese men were placed on a very low-calorie diet to achieve 15% weight loss from baseline weight and underwent two positron emission tomography scans before and two after weight loss, incorporating both fasted and fed states. MAIN OUTCOME MEASURES: Brain MOR availability and activation were measured by reductions in MOR availability (nondisplaceable binding potential) from the fed compared with the fasted-state scans. RESULTS: Baseline MOR nondisplaceable binding potential was reduced in obese compared with the lean and partially recovered obese after weight loss in regions that regulate homeostatic, hedonic, and emotional responses to feeding. Reductions in negative affect and feeding-induced MOR system activation in the right temporal pole were highly correlated in leans but not in obese men. A trend for an association between MOR activation in the right temporal pole before weight loss and weight regain 1 year was found. CONCLUSIONS: Although these preliminary studies have a small sample size, these results suggest that obesity and diet-induced weight loss impact central MOR binding and endogenous opioid system function. MOR system activation in response to an acute meal may be related to the risk of weight regain.
