Understanding the Landscape of Consultation Liaison Psychologists in Academic Medical Centers.

Current literature lacks data related to the role of psychologists on consultation-liaison (CL) services; previous data indicates only 4% of CL services are run by psychologists, while 32% of liaison mental health services include a psychologist. As CL psychologists' roles within hospitals grow, it is critical to identify clinical strategies and organizational structures of CL services across hospital systems. The current study seeks to provide a deeper understanding of CL psychologists' scope of work. Participants (N = 77) (15% response rate) completed a measure developed for this study, exploring psychologist roles, clinical practice, and departmental structures. Thirty-two percent of respondents were in Psychiatry Departments, 58% were in academic medical centers, almost half had training programs and the most frequently utilized billing code was: Given the limited data available, this study provided a contemporary and foundational understanding of the CL psychologist roles as well as future avenues of empirical inquiry such as discrete organization and structural characteristics.

Psychopathology, disordered eating, and impulsivity as predictors of weight loss 24 months after metabolic and bariatric surgery.

BACKGROUND: The relationship between theoretically relevant psychosocial and behavioral variables and outcomes of metabolic and bariatric surgery remains unclear. Some studies have found that the presence of psychopathology, disordered eating, and impulsivity, either before surgery or during the early postoperative period, is associated with suboptimal postoperative weight loss. Other studies have not found these relationships. OBJECTIVE: Examine the relationship between psychopathology, disordered eating, impulsivity, and weight loss 24 months postoperatively. SETTING: Two large, urban university health systems. METHODS: Participant characteristics were collected using validated interviews, patient-reported outcome measures, and computerized assessment methods. Linear mixed effect models were used to test the association of the variables of interest on percent weight loss (%WL). RESULTS: Three hundred participants were enrolled at baseline; weight data at 24 months were available for 227 participants; between 181 and 53 individuals completed other outcome measures. The mean %WL was 23.3 ± 9.9% at 24 months. Patients who underwent Roux-en-Y gastric bypass lost more weight than those who underwent sleeve gastrectomy. The presence of subjective binge episodes at baseline was related to a greater %WL at 24 months; there were no other baseline predictors. The presence of eating disorder diagnoses and disordered eating symptoms after surgery were associated with smaller weight losses over 24 months. Current and lifetime psychopathology and impulsivity were unrelated to %WL at 24 months. CONCLUSION: Disordered eating after bariatric surgery was associated with a smaller %WL at postoperative year 2. Additional monitoring of these symptoms in the early postoperative period is recommended. Psychotherapeutic and/or dietary interventions may promote more optimal weight loss outcomes.

Changes in Eating Behaviors and Their Relation to Weight Change 6 and 12 Months After Bariatric Surgery.

INTRODUCTION: Identifying eating behaviors associated with suboptimal weight loss following bariatric surgery remains important. This study assessed the relationship between eating behaviors and weight loss following bariatric surgery in a racially diverse sample. METHODS: Participants were assessed before surgery and 6 and 12 months postoperatively, with the Structured Clinical Interview for DSM-5, the Eating Disorder Examination-Bariatric Surgery Version, and validated measures assessing a range of eating behaviors. Linear mixed effect models were used to test the impact of eating behaviors on percent weight loss (%WL) at 6 and 12 months. RESULTS: We enrolled 300 participants (mean age 40.1 years; BMI 45.9 kg/m2; 87% women; 62% Black and 30% White). The majority (82%) underwent sleeve gastrectomy (SG). Mean %WL was 23.0 ± 5.1% at 6 months and 26.2 ± 7.6% at 12 months. Subjective binge episodes prior to surgery predicted greater %WL over the first 12 postoperative months (p = 0.028). Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and snacks per day were associated with smaller %WL over 12 months (all p's < 0.01). The presence of picking/nibbling and addictive-like eating behaviors was not associated with %WL at the end of the first postoperative year. CONCLUSION: Among a diverse participant sample, problematic eating behaviors following surgery were associated with smaller %WL over 12 months. Postoperative assessment and treatment of eating behaviors are needed to address these issues as they arise and to prevent attenuation of early weight loss in some patients.

Comparative Efficacy of Exercise Training and Conventional Psychotherapies for Adult Depression: A Network Meta-Analysis.

Objective: An estimated 3.8% of the global population experiences depression, according to the [2019] WHO report. Evidence supports the efficacy of exercise training (EX) for depression; however, its comparative efficacy to conventional, evidence-supported psychotherapies remains understudied. Therefore, we conducted a network meta-analysis to compare the efficacy of exercise training (EX), behavioral activation therapy (BA), cognitive-behavioral therapy (CBT), and non-directive supportive therapy (NDST). Methods: Our search was performed in seven relevant databases (inception to March 10, 2020) and targeted randomized trials comparing psychological interventions head-to-head and/or to a treatment as usual (TAU) or waitlist (WL) control for the treatment of adults (18 years or older) with depression. Included trials assessed depression using a validated psychometric tool. Results: From 28,716 studies, 133 trials with 14,493 patients (mean age of 45.8 years; 71.9% female) were included. All treatment arms significantly outperformed TAU (standard mean difference [SMD] range, -0.49 to -0.95) and WL (SMD range, -0.80 to -1.26) controls. According to surface under the cumulative ranking (SUCRA) probabilities, BA was mostly likely to have the highest efficacy (1.6), followed by CBT (1.9), EX (2.8), and NDST (3.8). Effect size estimates between BA and CBT (SMD = -0.09, 95% CI [-0.50 to 0.31]), BA and EX (-0.22, [-0.68 to 0.24]), and CBT and EX (-0.12, [-0.42 to 0.17]) were very small, suggesting comparable treatment effects of BA, CBT, and EX. With individual comparisons of EX, BA, and CBT to NDST, we found small to moderate effect sizes (0.09 to 0.46), suggesting EX, BA, and CBT may equally outperform NDST. Conclusions: Findings provide preliminary yet cautionary support for the clinical use of exercise training for adult depression. High study heterogeneity and lack of sound investigations of exercise must be considered. Continued research is needed to position exercise training as an evidence-based therapy.

Arousability as a trait predisposition to insomnia: multidimensional structure and clinical utility of the Spanish and English versions of the Arousal Predisposition Scale.

OBJECTIVES: Traits related to a hyper-reactive arousal system (arousability) and weakened sleep system (sleep reactivity) are considered predisposing factors for insomnia of potential clinical utility. However, research examining the psychometric properties (ie, reliability and validity) of the Arousal Predisposition Scale (APS) and its clinical utility (ie, cut-off scores) among population-based and clinical samples is very limited. METHODS: A total of 500 adults (41.8% female, 39.1 ± 15.9 years) from the general population in Spain and 217 adults (64.5% female, 46.0 ± 16.1 years) from a clinical sample in the United States completed the APS, as well as measures of sleep reactivity, insomnia severity, anxiety, depression, and stress. Structural equation modeling was used to conduct confirmatory factor analysis (CFA) of the APS. Correlation and receiver operating characteristic (ROC) analyses were used to determine convergent and predictive validity of the APS and its factors. RESULTS: The CFAs supported two dimensions of emotional reactivity (APS-ER, 9 items) and trait anxiety (APS-TA, 3 items) in both independent samples. APS-ER was associated with sleep reactivity and performed better than APS-TA when predicting clinically significant sleep reactivity and similarly when predicting clinically significant insomnia severity. CONCLUSIONS: Our findings support the specificity of emotional reactivity and sleep reactivity as trait predispositions to insomnia, while trait anxiety is a predisposing factor for the comorbidity of insomnia with state anxiety rather than a specific diathesis for insomnia. These data provide further support for the diathesis-stress model of insomnia and, as a transdiagnostic process, its potential etiological link with psychopathology.

Psychopathology, disordered eating, and impulsivity in patients seeking bariatric surgery.

BACKGROUND: Most patients who undergo bariatric surgery experience significant weight loss and improvements in obesity-related co-morbidities in the first 6-18 months after surgery. However, 20%-30% of patients experience suboptimal weight loss or significant weight regain within the first few postoperative years. Psychosocial functioning may contribute to suboptimal weight loss and/or postoperative psychosocial distress. OBJECTIVE: Assess psychosocial functioning, eating behavior, and impulsivity in patients seeking bariatric surgery. SETTING: Two university hospitals. METHODS: Validated interviews and questionnaires. Impulsivity assessed via computer program. RESULTS: The present study included a larger (n = 300) and more racially diverse (70% non-White) sample than previous studies of these relationships. Forty-eight percent of participants had a current psychiatric diagnosis and 78% had at least 1 lifetime diagnosis. Anxiety disorders were the most common current diagnosis (25%); major depressive disorder was the most common lifetime diagnosis (44%). Approximately 6% of participants had a current alcohol or substance use disorder; 7% had a positive drug screen before surgery. A current psychiatric diagnosis was associated with greater symptoms of food addiction and night eating. Current diagnosis of alcohol use disorder or a lifetime diagnosis of anxiety disorders was associated with higher delay discounting. CONCLUSION: The study identified high rates of psychopathology and related symptoms among a large, diverse sample of bariatric surgery candidates. Psychopathology was associated with symptoms of disordered eating and higher rates of delay discounting, suggesting impulse control issues.

Psychopathology, disordered eating, and impulsivity as predictors of outcomes of bariatric surgery.

Outcomes of bariatric surgery, while frequently impressive, are not universal and vary between patients and across surgical procedures. Between 20% and 30% of patients experience suboptimal weight loss or significant weight regain within the first few postoperative years. The reasons for this are not fully understood, but likely involve both physiologic processes, behavioral factors, and psychological characteristics. Evidence suggests that preoperative psychosocial status and functioning can contribute to suboptimal weight losses and/or postoperative psychosocial distress. Much of this work has focused on the presence of recognized psychiatric diagnoses and with particular emphasis on mood disorders as well as binge eating disorder. Several studies have suggested that the presence of preoperative psychopathology is associated with suboptimal weight losses, postoperative complications, and less positive psychosocial outcomes. Contemporary psychological theory suggests that it may be shared features across diagnoses, rather than a discrete diagnosis, that better characterizes psychopathology. Mood and substance use disorders as well as binge eating disorder, share common features of impulsivity, although clinicians and researchers often use complementary, yet different terms, such as emotional dysregulation or disinhibition (i.e., loss of control over eating, as applied to food intake), to describe the phenomenon. Impulse control is a central factor in eating behavior and extreme obesity. It also may contribute to the experience of suboptimal outcomes after bariatric surgery, including smaller than expected weight loss and psychosocial distress. This paper reviews the literature in these areas of research and articulates a direction for future studies of these complex relationships among persons with extreme obesity.

Am I (hyper)aroused or anxious? Clinical significance of pre-sleep somatic arousal in young adults.

Self-reported somatic arousal remains a challenging clinical construct, particularly because only a subset of patients report symptoms such as racing heart, palpitations or increased body temperature interfering with their sleep. It is unclear whether self-reported somatic arousal is a marker of hyperarousal or co-morbid clinical anxiety in individuals with insomnia. Participants included 196 young adults aged 20.2 ±â€…1.0 years old who were predominantly females (75%). About 39% of the sample reported subthreshold insomnia, and about 8% reported clinically significant insomnia, based on their Insomnia Severity Index. Participants completed the Pre-Sleep Arousal Scale, Beck Anxiety Inventory, Beck Depression Inventory, Arousal Predisposition Scale, and Ford Insomnia Response to Stress Test. Multivariable stepwise regression assessed which factors were independently associated with pre-sleep cognitive (Pre-Sleep Arousal Scale-Cognitive) and somatic (Pre-Sleep Arousal Scale-Somatic) arousal. Receiver-operating characteristic analysis assessed the predictive value to identify clinically significant anxiety (Beck Anxiety Inventory ≥ 20), insomnia (Insomnia Severity Index ≥ 15) and arousability (Arousal Predisposition Scale ≥ 32). Beck Anxiety Inventory (ß = 0.42) was the best single correlate of Pre-Sleep Arousal Scale-Somatic, while Insomnia Severity Index (ß = 0.33) was of Pre-Sleep Arousal Scale-Cognitive. A Pre-Sleep Arousal Scale-Somatic score of 12 or more identified those with clinically significant anxiety with 65% specificity and 65% sensitivity, while a cut-off score of 14 increased its sensitivity (86%). Self-reported pre-sleep somatic arousal may be an index of co-morbid clinical anxiety in individuals with insomnia. These findings aid clinicians with assessment and treatment, particularly in the absence of clinical guidelines indicating when somatically focused relaxation techniques should be included as part of multicomponent cognitive behavioural treatment of insomnia.

Patients' Reported Usage of Weight Management Skills Following Bariatric Surgery.

Little is known about which specific weight management skills bariatric patients find most and least valuable. Participants completed a measure assessing their usage of weight management skills at a follow-up appointment one or more years after undergoing bariatric surgery. Decreased usage of skills was associated with unsuccessful weight outcome, defined as losing less than 50% of excess weight, as well as weight regain. Weighing regularly was the skill selected most often by successful participants as helpful, and was chosen by a significantly smaller percentage of unsuccessful participants and those who regained a clinically significant amount of weight. A majority of both successful and unsuccessful participants indicated that they had discontinued food journaling. Weighing regularly may be perceived as a more useful method of self-monitoring.

Impact of the Metabolic Syndrome on Mortality is Modified by Objective Short Sleep Duration.

BACKGROUND: To examine whether objective sleep duration is an effect modifier of the impact of metabolic syndrome (MetS) on all-cause and cardiovascular disease/cerebrovascular mortality. METHODS AND RESULTS: We addressed this question in the Penn State Adult Cohort, a random, general population sample of 1344 men and women (48.8±14.2 years) who were studied in the sleep laboratory and followed up for 16.6±4.2 years. MetS was defined by the presence of 3 or more of obesity (≥30 kg/m2), elevated total cholesterol (≥200 mg/dL), triglycerides (≥150 mg/dL), fasting glucose (≥100 mg/dL), and blood pressure (≥130/85 mm Hg). Polysomnographic sleep duration was classified into clinically meaningful categories. Among the 1344 participants, 22.0% of them died during the follow-up. We tested the interaction between MetS and polysomnographic sleep duration on mortality using Cox proportional hazard models controlling for multiple potential confounders (P<0.05). The hazard ratios (95% CI) of all-cause and cardiovascular disease/cerebrovascular mortality associated with MetS were 1.29 (0.89-1.87) and 1.49 (0.75-2.97) for individuals who slept ≥6 hours and 1.99 (1.53-2.59) and 2.10 (1.39-3.16) for individuals who slept <6 hours. Interestingly, this effect modification was primarily driven by the elevated blood pressure and glucose dysregulation components of MetS. CONCLUSIONS: The risk of mortality associated with MetS is increased in those with short sleep duration. Short sleep in individuals with MetS may be linked to greater central autonomic and metabolic dysfunction. Future clinical trials should examine whether lengthening sleep improves the prognosis of individuals with MetS.

Findings from an online behavioural weight management programme provided with or without a fortified diet beverage.

The present multi-centre randomised weight-loss trial evaluated the efficacy of a low-intensity 12-week online behavioural modification programme, with or without a fortified diet beverage using a 2 × 2 factorial design. A total of 572 participants were randomised to: (1) an online basic lifestyle information (OBLI) intervention, consisting of one online informational class about tips for weight management; (2) an online behavioural weight management (OBWM) intervention, entailing 12 weekly online classes focused on weight-loss behaviour modification; (3) an OBLI intervention plus a fortified diet cola beverage (BEV) containing green tea extract (total catechin 167 mg), soluble fibre dextrin (10 g) and caffeine (100 mg) (OBLI+BEV); (4) OBWM+BEV. Assessments included height, weight, dual-energy X-ray absorptiometry-derived body composition, and waist circumference (WC). Attrition was 15·7 %. Intention-to-treat (ITT) models demonstrated a main effect for type of Internet programme, with those assigned to the OBWM condition losing significantly more weight (F= 7·174; P= 0·008) and fat mass (F= 4·491; P= 0·035) than those assigned to the OBLI condition. However, there was no significant main effect for the OBWM condition on body fat percentage (F= 2·906; P= 0·089) or WC (F= 3·351; P= 0·068), and no significant main effect for beverage use or significant interactions between factors in ITT models. A 12-week, low-intensity behaviourally based online programme produced a greater weight loss than a basic information website. The addition of a fortified diet beverage had no additional impact.

Similarities and differences between weight loss maintainers and regainers: a qualitative analysis.

Obesity is remarkably refractory to treatment. Despite a plethora of quantitative studies, little qualitative research has been conducted on the topic of weight loss maintenance. This study used six focus groups to explore which factors promoted or prevented maintaining weight loss among a diverse, urban population. Eligible participants were those who had intentionally lost ≥10% of their body weight in the past 2 years and were categorized as either "regainers" or "maintainers" using self-reported length of weight maintenance and amount (%) regained. Regainers had regained ≥33% of their weight loss and maintainers had regained ≤15%. Participants (n=29) were predominantly African-American (58.6%) females (65.6%) with a mean age of 46.9±11.2 years. Four themes reflected similarities between regainers and maintainers, and four reflected differences between the groups. Both groups experienced lapses, used clothing fit for feedback on weight status, desired greater support during maintenance, and decreased self-monitoring of food intake over time. When compared with regainers, maintainers more often continued strategies used during weight loss, weighed themselves regularly, and used productive problem-solving skills and positive self-talk. Regainers experienced greater difficulty independently continuing food and exercise behaviors during maintenance, identifying decreased accountability and waning motivation as barriers. These findings suggest that weight loss maintenance efforts can be improved by addressing challenges such as long-term self-monitoring and problem-solving skills, and that maintenance success might depend on how people think as much as what they do.

The effects of a commercially available weight loss program among obese patients with type 2 diabetes: a randomized study.

The purpose of this study was to assess the effects of a commercially available weight loss program on weight and glycemic control among obese patients with type 2 diabetes. Participants included 69 patients (49 females, 20 males) with type 2 diabetes who had a mean +/- SD age of 52.2 +/- 9.5 years, a body mass index of 39.0 +/- 6.2 kg/m(2), and hemoglobin A1c (HbA1c) of 7.5 +/- 1.6%. Over half (52.2%) of the participants were African American. Participants were randomly assigned to: 1) a portion-controlled diet (NutriSystem D) (PCD) or 2) a diabetes support and education (DSE) program. After the initial 3 months, the PCD group continued on the PCD for the remaining 3 months, and the DSE group crossed over to PCD for the remaining 3 months. The primary comparison for this study was at 3 months. At 3 months, the PCD group lost significantly more weight (7.1 +/- 4%) than the DSE group (0.4 +/- 2.3%) (P < 0.0001). From 3 to 6 months the change in weight for both groups was statistically significant. After 3 months, the PCD group had greater reductions in HbA1c than the DSE group (-0.88 +/- 1.1 vs 0.03 +/- 1.09; P < 0.001). From 3 to 6 months the PCD group had no further change in HbA1c, while the DSE group showed a significant reduction. These data suggest that obese patients with type 2 diabetes will experience significant improvements in weight, glycemic control, and cardiovascular disease risk factors after the use of a commercially available weight management program.
