Associations between relationship stability, relationship quality, and weight loss outcomes among bariatric surgery patients.

After weight loss surgery (WLS), psychosocial functioning, including the quality of social relationships, generally improves, but for a minority, relationships worsen. We examined how changes in relationship stability and quality from pre- to post-WLS relate to long-term weight loss outcomes. Postoperative patients (N=361) completed surveys which queried relationship changes and weight loss. The sample was 95.9% Caucasian, 80.1% female, averaged 7.7years post-WLS, with a mean age at surgery of 47.7years (range 21-72); 87.3% had a Roux-en-Y gastric bypass. Four relationship status groups were created: Not in a relationship at surgery or follow-up (No-Rel, n=66; 18.2%); Post-WLS relationship only (New-Rel, n=23; 6%); Pre-WLS relationship only (Lost-Rel, n=17; 5%); and Pre-Post Relationship (Maintainer, n=255; 70.6%). Current BMI was 34.5 for No-Rel; 40.5 for New-Rel; 37.4 for Lost-Rel; 33.3 for Maintainers (p<.05 for Maintainers and No-Rel vs. New-Rel). These same group differences were significant for weight loss, which was not associated with gender, time since surgery, or age at time of surgery, but was associated with pre-WLS BMI (lower pre-WLS BMI was associated with greater %EWL). Analyses were repeated with pre-WLS BMI as a covariate; group differences remained significant [F (3, 355)=3.09, p=.03], as did pre-WLS BMI, [F (1, 355)=9.12, p=.003]. Among Maintainers, relationship quality was associated with weight loss outcomes: those with improved relationships post-WLS had significantly greater %EWL [F (2, 234)=15.82, p<0.000; p<.05 for Improved>(Stayed Same=Got Worse)]. Findings support the importance of assessing relationship stability and quality in pre-WLS candidates, as healthy and stable relationships may support improved long-term outcomes. Interventions to improve relationships pre-and post-WLS may increase both quality of life and weight loss outcomes.

When treating the pain is not enough: a multidisciplinary approach for chronic pelvic pain

Chronic pelvic pain (CPP) is related to psychological distress and interference in daily activities; however, CPP is not as extensively researched as other forms of chronic pain. Therefore, the purpose of this study was to investigate the relationships among pain, psychological distress, and functional impairment in patients with CPP. There were chart reviews conducted of 107 female patients who completed a psychiatric evaluation at a specialty, CPP clinic as a part of a multidisciplinary evaluation. Results suggest that psychological distress and impairment in daily activities are common in CPP patients. Most areas of functional impairment were not associated with pain variables. Rather, several forms of functional impairment were related to higher levels of depression and anxiety. Results from this study suggest the possibility that psychiatric symptoms are contributing to functional impairment in this population. These findings highlight the importance of a multidisciplinary approach in the evaluation and treatment of CPP patients to help decrease functional impairment in these patients.

Pursuing bariatric surgery in an urban area: Gender and racial disparities and risk for psychiatric symptoms

BACKGROUND Bariatric surgery is effective for weight loss; however, only a small percentage of those who qualify choose to pursue it. Additionally, although psychiatric symptoms appear to be common among candidates, the risk factors for symptoms are not known. Therefore, the purpose of this study was to examine the characteristics of those who are pursuing bariatric surgery in an urban area, whether demographic disparities continue to exist, and identify characteristics of those who may be at higher risk for experiencing psychiatric symptoms. METHODS There were 424 bariatric candidates who completed a required psychological evaluation prior to bariatric surgery. RESULTS AND CONCLUSIONS Bariatric surgery candidates tended to be middle-aged, Caucasian females, which was unexpected when compared to the rates of obesity among these groups. Therefore, it appears that there are disparities in who chooses to seek out bariatric surgery compared to those who may qualify due to their obesity status. Cultural factors may play a role in why males and African Americans seek out bariatric surgery less frequently. Psychiatric symptoms among candidates are also common, with depression symptoms increasing with age and BMI. Perhaps the compounding effects of medical comorbidities over time are contributing to greater depressive symptoms in the older patients. Findings from this study suggest that we may need to explore ways of encouraging younger patients, males, and ethnic minorities to pursue bariatric surgery to increase weight loss success and decrease medical comorbidities.

Beyond Operant Theory of Observer Reinforcement of Pain Behavior

Operant theory has guided theoretical and empirical developments in the field of chronic pain for decades. This model has been the primary perspective from which behavioral interventions for chronic pain have been drawn. Recent evidence suggests that there is a need to expand upon the operant model with conceptual models found in the interpersonal, empathy, and pain communication literature. Although they each have a unique focus (e.g., communication, empathy), they each highlight the interpersonal dynamics that can impact the experience of pain for patients. Evidence is needed to know the extent to which treatment can intervene on these influential relationship variables and further, to elucidate the unique interplay between the communication of spouses in the context of pain and behavioral responses of close others. The theoretical models found in the interpersonal, empathy, and pain communication literature provide a way to view pain expressions in the context of the relationship and the deeper idiosyncratic meaning that these may have for an individual with chronic pain (ICP). These models provide a richer understanding of the motivations and antecedents that lead an observer to respond to a loved one’s pain behaviors and the effects of different observer responses on an ICP’s subjective rating of pain. Addressing communication, empathy, and intimacy correlates of observer responses to pain and gathering a better understanding of the communicative role of pain behaviors is necessary, as this is likely the direction that treatments for chronic pain are headed.
