Application of an egocentric social network approach to examine changes in social connections following treatment for anxiety and depression: A novel measurement tool for clinical trials research? Soc Sci Med 2024; 350:116914. [PMID: 38696938 DOI: 10.1016/j.socscimed.2024.116914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 04/02/2024] [Accepted: 04/23/2024] [Indexed: 05/04/2024]
Abstract
The epidemic of loneliness and social isolation has been recognized as a public health crisis warranting the same prioritization as other public health issues today, such as obesity, substance use disorders, and tobacco use. Social disconnection is particularly prevalent and disabling among individuals with anxiety and depression, yet it is inadequately evaluated and addressed in most clinical psychology treatment research. Studies generally employ global measures of perceived connectedness, loneliness, or relationship satisfaction, limiting understanding about elements of one's social network that may change with treatment. This study examined changes in the degree (number of people nominated) and quality of one's social network from pre-to post-treatment using an egocentric social network approach in 59 adults (mean age = 30.8 years, range = 18 to 54) with clinically elevated anxiety or depression who were randomized to a cognitive and behavioral positive valence treatment versus waitlist. Participants (egos) named people in their lives (alters) with whom they discussed important issues or spent free time. For each alter, participants rated how close they felt, how close they thought the alter felt to them, and how frequently they communicated. Linear regressions, which included treatment group as a predictor, revealed no group differences in changes in network degree, perceived alter feelings of closeness, or communication frequency, despite prior findings from this sample indicating larger increases in perceived global connectedness in the treatment group. Unexpectedly, the control group reported a greater increase in perceived closeness to alters. Post-hoc analyses revealed this was explained by the treatment group identifying more distal social ties (e.g., extended family, colleagues, roommates) as alters following treatment - an outcome positively associated with global improvements in connectedness. This proof-of-concept study suggests egocentric social network surveys may provide unique information on treatment-related changes in social functioning. Suggestions are provided for adaptations to facilitate application of social network surveys to mental health treatment research.

Amplification of Positivity Treatment for Anxiety and Depression: A Randomized Experimental Therapeutics Trial Targeting Social Reward Sensitivity to Enhance Social Connectedness. Biol Psychiatry 2024; 95:434-443. [PMID: 37607657 DOI: 10.1016/j.biopsych.2023.07.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 07/04/2023] [Accepted: 07/25/2023] [Indexed: 08/24/2023]
Abstract
BACKGROUND Social disconnection is common and causes significant impairment in anxiety and depressive disorders, and it does not respond sufficiently to available treatments. The positive valence system supports social bond formation and maintenance but is often hyporesponsive in people with anxiety or depression. We conducted an experimental therapeutics trial to test the hypothesis that targeting positive valence processes through cognitive and behavioral strategies would enhance responsivity to social rewards, a core mechanism underlying social connectedness. METHODS Sixty-eight adults who endorsed clinically elevated anxiety and/or depression with social impairment were randomized 1:1:1 to 5 (n = 23) or 10 (n = 22) sessions of amplification of positivity (AMP) treatment or waitlist (n = 23). Pre- to posttreatment change in striatal activity (primary outcome) during social reward anticipation was measured using functional magnetic resonance imaging, and reactivity to a social affiliation task (secondary) and self-reported social connectedness (exploratory) were examined. Primary analyses compared AMP (doses combined) versus waitlist. A second aim was to compare the effects of different doses. RESULTS AMP engaged the hypothesized treatment target, leading to greater striatal activation during anticipation of social rewards versus waitlist (d = 1.01 [95% CI = 0.42-1.61]; largest striatal volume). AMP yielded larger improvements in positive affect and approach behavior during the affiliation task (but not other outcomes) and social connectedness. Larger striatal and social connectedness increases were observed for 5-session versus 10-session AMP (d range = 0.08-1.03). CONCLUSIONS Teaching people with anxiety or depression strategies to increase positive thoughts, behaviors, and emotions enhances activity in brain regions that govern social reward processing and promotes social connectedness. Social reward sensitivity may be a transdiagnostic target for remediating social disconnection.

A Cluster Randomized Trial of Primary Care Practice Redesign to Integrate Behavioral Health for Those Who Need It Most: Patients With Multiple Chronic Conditions. Ann Fam Med 2023; 21:483-495. [PMID: 38012036 PMCID: PMC10681692 DOI: 10.1370/afm.3027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 05/05/2023] [Accepted: 05/31/2023] [Indexed: 11/29/2023] Open
Abstract
PURPOSE Patient outcomes can improve when primary care and behavioral health providers use a collaborative system of care, but integrating these services is difficult. We tested the effectiveness of a practice intervention for improving patient outcomes by enhancing integrated behavioral health (IBH) activities. METHODS We conducted a pragmatic, cluster randomized controlled trial. The intervention combined practice redesign, quality improvement coaching, provider and staff education, and collaborative learning. At baseline and 2 years, staff at 42 primary care practices completed the Practice Integration Profile (PIP) as a measure of IBH. Adult patients with multiple chronic medical and behavioral conditions completed the Patient-Reported Outcomes Measurement Information System (PROMIS-29) survey. Primary outcomes were the change in 8 PROMIS-29 domain scores. Secondary outcomes included change in level of integration. RESULTS Intervention assignment had no effect on change in outcomes reported by 2,426 patients who completed both baseline and 2-year surveys. Practices assigned to the intervention improved PIP workflow scores but not PIP total scores. Baseline PIP total score was significantly associated with patient-reported function, independent of intervention. Active practices that completed intervention workbooks (n = 13) improved patient-reported outcomes and practice integration (P ≤ .05) compared with other active practices (n = 7). CONCLUSION Intervention assignment had no effect on change in patient outcomes; however, we did observe improved patient outcomes among practices that entered the study with greater IBH. We also observed more improvement of integration and patient outcomes among active practices that completed the intervention compared to active practices that did not. Additional research is needed to understand how implementation efforts to enhance IBH can best reach patients.

COVID-19 vaccine hesitancy: Associations with gender, race, and source of health information. FAMILIES, SYSTEMS & HEALTH : THE JOURNAL OF COLLABORATIVE FAMILY HEALTHCARE 2022; 40:252-261.

Abstract
INTRODUCTION Vaccinations for COVID-19 are being distributed, yet vaccine hesitance is placing many people at risk for infection, negative outcomes, and compromising public health. Given primary care clinics are where people most often interact with health care providers, understanding factors associated with this hesitance may help providers in integrated primary care settings best address this hesitance. METHOD Between September and November of 2020, a survey was sent to all primary care patients within a large southern California health system, with over 10,000 responding (22% response rate). Survey items included sociodemographic variables, level of vaccine hesitance, "proximity to COVID" (e.g., direct exposure to COVID-19 and consequences), as well as a patient's primary source of health information (e.g., traditional news, social media, etc.). Responses assessed the strength of hesitance. RESULTS Results showed that while 78% of participants "strongly" believed vaccines generally are a good way to protect from illness, only 51% reported strong willingness to get the COVID-19 vaccine. Consistent with previous surveys, younger patients were more hesitant to get vaccinated, as were people of color. Unique to this survey was the finding that those relying on social media, faith-based organizations, or family/friends for health information had the greatest vaccine hesitance. DISCUSSION While our patient sample was less hesitant than other U.S. adult samples previously reported in the literature, our data suggest that targeting those patients who report reliance on nontraditional health information sources should be approached by primary care teams, including behavioral health providers, to address vaccine hesitancy.

Integrating Behavioral Health and Primary Care (IBH-PC) to improve patient-centered outcomes in adults with multiple chronic medical and behavioral health conditions: study protocol for a pragmatic cluster-randomized control trial. Trials 2021; 22:200. [PMID: 33691772 PMCID: PMC7945346 DOI: 10.1186/s13063-021-05133-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 02/15/2021] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Chronic diseases that drive morbidity, mortality, and health care costs are largely influenced by human behavior. Behavioral health conditions such as anxiety, depression, and substance use disorders can often be effectively managed. The majority of patients in need of behavioral health care are seen in primary care, which often has difficulty responding. Some primary care practices are providing integrated behavioral health care (IBH), where primary care and behavioral health providers work together, in one location, using a team-based approach. Research suggests there may be an association between IBH and improved patient outcomes. However, it is often difficult for practices to achieve high levels of integration. The Integrating Behavioral Health and Primary Care study responds to this need by testing the effectiveness of a comprehensive practice-level intervention designed to improve outcomes in patients with multiple chronic medical and behavioral health conditions by increasing the practice's degree of behavioral health integration. METHODS Forty-five primary care practices, with existing onsite behavioral health care, will be recruited for this study. Forty-three practices will be randomized to the intervention or usual care arm, while 2 practices will be considered "Vanguard" (pilot) practices for developing the intervention. The intervention is a 24-month supported practice change process including an online curriculum, a practice redesign and implementation workbook, remote quality improvement coaching services, and an online learning community. Each practice's degree of behavioral health integration will be measured using the Practice Integration Profile. Approximately 75 patients with both chronic medical and behavioral health conditions from each practice will be asked to complete a series of surveys to measure patient-centered outcomes. Change in practice degree of behavioral health integration and patient-centered outcomes will be compared between the two groups. Practice-level case studies will be conducted to better understand the contextual factors influencing integration. DISCUSSION As primary care practices are encouraged to provide IBH services, evidence-based interventions to increase practice integration will be needed. This study will demonstrate the effectiveness of one such intervention in a pragmatic, real-world setting. TRIAL REGISTRATION ClinicalTrials.gov NCT02868983 . Registered on August 16, 2016.

Abstract
Essential to the implementation of a patient-centered medical home is use of evidence-based interventions by a well-coordinated team of providers in a cost-effective manner. Group Medical Visits (GMVs), designed to increase self-management behaviors in patients with chronic illness, have shown inconsistently to be efficacious. Despite the modest results reported thus far in the literature, GMVs have been promoted by the American Academy of Family Physicians as an important component in the patient-centered medical home. This paper describes the challenges of translating GMVs into clinical practice when research support is not available. A review of 5+ years experience in conducting GMVs in clinical practice, including the numerous barriers, is presented through a "three-world view" model utilized by collaborative care leaders. This review is followed by a comparison of variables extracted from patients' electronic health records of those who participated in GMVs to similar patients who did not participate in GMVs. Results suggest that outcomes often reported in efficacy trials are not easily obtained in real clinical practice. Overcoming the operational and financial obstacles to offering GMVs is necessary before they can be promoted as essential elements in a patient-centered medical home.

Abstract
Objective The purpose of this study was to investigate patients’ experiences when diagnosed with type 2 diabetes and diabetes-related distress and self-management years later. Method One hundred seventy-nine adults with type 2 diabetes, 1 to 5 years after diagnosis, completed a questionnaire assessing what they were told and what was recommended at diagnosis as well as current diet, physical activity, and diabetes distress. Results Most patients (60%) expressed confidence in their health care provider (HCP) at diagnosis, but 30% reported that a clear action plan was not communicated. Current diabetes distress was significantly lower among those who reported being reassured at diagnosis that diabetes could be managed successfully and had developed a clearer action plan with their HCP. Patients’ current dietary behaviors were significantly better among those receiving a clearer action plan at diagnosis. Conclusion Patients’ retrospective reports of reassuring HCP messages when diagnosed, along with the presentation of a clear action plan, are associated with less diabetes distress and better self-management at 1 to 5 years after diagnosis. Practical implications Findings suggest a long-lasting impact on patients’ attitudes and behaviors when the diagnosis of type 2 diabetes is delivered clearly, a sense of hope is provided, and a specific care plan is put forward.

Abstract
OBJECTIVE To compare mental health treatment history and preferences in older and younger primary care patients. METHOD We surveyed 77 older (60+) and 312 younger adult primary care patients from four outpatient medical clinics about their mental health treatment history and preferences. RESULTS Older adults were less likely than younger adults to report a history of mental health treatment (29% vs. 51%) or to be currently receiving treatment (11% vs. 23%). They were also less likely to indicate that they currently desire help with emotional problems (25% vs. 50%). Older adults were more likely to hold a belief in self-reliance that could limit their willingness to accept treatment for mental health problems, although they were less likely than younger adults to identify other barriers to treatment. Older adults reported that they were less likely to attend programs in primary care targeting mental health issues (counseling, stress management) than younger adults, although they were as willing as younger adults to attend programs targeting physical health issues (healthy living class, fitness program). Age remained a significant predictor of mental health treatment history and preferences even after controlling for other demographic variables. CONCLUSION These results suggest that older adults in the primary care setting may be less willing to accept mental health services than younger adults. Results further suggest that perceived barriers may differ for older and younger patients, which may indicate the need for age-specific educational messages and services targeted to older adults in primary care.

Abstract
Cluster headache, an excruciating, unilateral headache usually accompanied by conjunctival injection and lacrimation, can occur episodically or chronically, and can be difficult to treat. Existing effective treatments may be underused because of underdiagnosis of the syndrome. Oxygen and sumatriptan have been demonstrated to be effective in the acute treatment of cluster headaches. Verapamil has been shown to be effective for prophylaxis. For cluster headache completely refractory to all treatments, surgical modalities and newer interventions such as the implantation of stereotactic electrodes may be useful. Patients should be encouraged to avoid possible triggers such as smoking or alcohol consumption, especially during the duster period. The intensity of duster headache pain leads to ethical concerns among researchers over the use of placebo, making randomized controlled trials difficult. As new technology and genetic studies clarify the etiology of duster headache, it is possible that more specific therapies will emerge.

Abstract
PURPOSE We sought to evaluate 3 methods for imputing utility-based outcomes from clinical trial data measured using the Medical Outcomes Study 36-Item Short Form (SF-36). SUBJECTS Our subjects included 131 male and 505 female adults (mean age, 55.42 +/- 12.59 years) who were participating in a randomized clinical trial evaluating a new treatment of adults with rheumatoid arthritis (RA). MEASURES Participants completed the SF-36, 2 versions of the Health Utilities Index (HUI-2 and HUI-3), the EuroQol EQ-5D, and the Health Assessment Questionnaire (HAQ). SF-36 scores were transformed to utility-based scores using 4 methods developed independently by Fryback, Nichol, and Brazier. RESULTS All 4 imputed scores were significantly correlated with HUI-2, HUI-3, EQ-5D, and the disease-specific HAQ scores at baseline and at the end of the clinical trial period (P < 0.05). Changes in the imputed scores from baseline to end of study also were significantly correlated with corresponding changes in the measured utility scores and the HAQ score (P < 0.0001). For all imputed and measured scores, changes from baseline were associated with the clinical assessments, ACR20 and ACR50. The associations were stronger for the utility-based measures than the imputed indices. Both imputed and measured scores were sensitive to change in the clinical trial. However, mean scores for the HUI-3 and the Brazier VAS were significantly lower than for the other measures. CONCLUSION Imputed utility-based score estimates are significantly correlated with measured utility outcomes. However, the imputed measures had more constrained variability, showed poorer correspondence to the ACR20 and ACR50 benchmarks, and predicted less than half of the variance in actual utility-based outcomes. Therefore, directly assessed, not imputed, utility-based measures should continue to be favored for cost-effectiveness analysis.

Abstract
OBJECTIVE To evaluate the self-administered Quality of Well-Being (QWB-SA) Scale for patients with rheumatic diseases. METHODS Family medicine patients (n = 562) and rheumatology patients (n = 334) were assessed using the following tools: QWB-SA, Health Assessment Questionnaire (HAQ), Arthritis Impact Measurement Scales (AIMS), and Rapid Assessment of Disease Activity in Rheumatology (RADAR). RESULTS Patients with arthritis had significantly lower QWB-SA scores and significantly higher HAQ scores than family medicine patients with and without adjustment for covariates. The QWB-SA was significantly associated with quartiles from the RADAR, AIMS, and HAQ, providing evidence for the validity of the generic measure in patients with arthritis. Discriminant function analysis was used to create an arthritis-specific scoring system for the QWB-SA. Analyses demonstrated systematic relationships between the Quality of Well-Being arthritis composite and the disease-specific RADAR, AIMS, and HAQ. CONCLUSIONS Evidence supports the validity of the QWB-SA for patients with rheumatic diseases. QWB-SA items can be used to calculate an arthritis-specific score. The QWB-SA can be used to gain generic information for cost-utility analysis and disease-specific outcomes information for patients with arthritis.

Abstract
BACKGROUND This study evaluated the cross-sectional and longitudinal relationship between depression severity and the Quality of Well-Being scale self-administered version (QWB-SA) in subjects diagnosed with current major depression. METHODS The research design was prospective and observational. Data were collected on a convenience sample of 58 subjects. Additional measures included the Quality of Well-Being scale interviewer-version (interviewer-QWB), Hamilton Rating Scale for Depression (HRSD-17), Beck Depression Inventory, and each were collected at baseline, 4 weeks, and 4 months postmedication treatment. RESULTS Cross-sectional and longitudinal QWB-SA scores were significantly correlated with depression severity and the interviewer-QWB. Treatment response, defined as 50% improvement in HRSD-17, was associated with 0.10 and 0.16 unit changes in the QWB-SA at 4 weeks and 4 months, respectively. The QWB-SA was significantly and negatively correlated with cross-sectional and longitudinal depression severity. LIMITATIONS The study design was observational and used a convenience sample of subjects. CONCLUSIONS The QWB-SA is less expensive to administer than the interviewer-QWB and is a useful alternative for determining the effectiveness and cost-effectiveness of treatments for depression relative to other physical and mental illness treatments.

Abstract
BACKGROUND The importance of psychological morbidity after major trauma, such as posttraumatic stress disorder (PTSD), is continuing to gain attention in trauma outcomes research. The Trauma Recovery Project is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life (QoL) and PTSD. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to examine gender differences in prolonged PTSD (L-PTSD) and to assess the impact of PTSD by gender on QoL at the 6-, 12-, and 18-month follow-up time points in the Trauma Recovery Project population. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the study. The enrollment criteria for the study included the following: age 18 years and older; admission Glasgow Coma Scale score of 12 or greater; and length of stay greater than 24 hours. QoL was measured after injury using the Quality of Well-being (QWB) scale, a sensitive index to the well end of the functioning continuum (range: 0 = death to 1.000 = optimum functioning). Early symptoms of acute stress reaction (SASR) at discharge were assessed using the Impact of Events Scale (score > 30 = SASR). PTSD at 6-, 12-, and 18-month follow-up was diagnosed using standardized Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. PTSD (L-PTSD) was diagnosed if full or partial (F + P) or full (F) PTSD Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria were present at all follow-up time points. RESULTS PTSD (L-PTSD) (F + P) was diagnosed in 35% (221 of 627) of patients at follow-up. PTSD (L-PTSD) (F) was present in 32% (153 of 627). Women were at significantly higher risk of PTSD (F + P) (odds ratio = 2.4, p = 0.001) and PTSD (F) (odds ratio = 2.8, p = 0.001) than men. The association of gender with PTSD was independent of mechanism and injury event-related factors such as perceived threat to life. In multivariate logistic regression, female gender, perceived threat to life, and SASR were strongly and independently associated with PTSD risk. Women were also at risk for worse QWB outcomes; beginning at discharge through the 18-month follow-up, women had significantly lower QWB scores at each follow-up time than men, regardless of prolonged PTSD status. CONCLUSION These results provide important new evidence that high rates of PTSD persist in the long-term aftermath of major trauma. The association of gender with PTSD was independent of mechanism and injury event-related factors such as perceived threat to life. Within categories of specific mechanism of injury and injury event-related factors, women were at significantly higher risk of prolonged PTSD onset. Prolonged PTSD was associated with significantly reduced quality of life in both men and women, with markedly worse QWB outcomes in women regardless of prolonged PTSD status.

Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. RESULTS PTSD was diagnosed in 32% (261 of 824) patients at 6-month follow-up. Perceived threat to life predicted PTSD onset (odds ratio [OR], 1.6; p < 0.01) and early SASR (OR, 2.2; p < 0.001). PTSD was more frequent in women (39%) than in men (29%) and in younger low-income patients. Other major risk factors were penetrating trauma (OR, 2.3; p < 0.001) and assaults (OR, 1.5; p < 0.05). PTSD had a major impact on QoL at 6-, 12-, and 18-month follow-up (Quality of Well-being scale score: 6 months, 0.576 vs. 0.658; 12 months, 0.620 vs. 0.691; 18 months, 0.620 vs. 0.700; p < 0.0001). CONCLUSION These results provide new and provocative evidence that perceived threat to life and mechanism predict PTSD after major traumatic injury. PTSD had a prolonged and profound impact on short- and long-term outcome and QoL.

Abstract
Screening tests for colon cancer, breast cancer, and elevated serum cholesterol are widely advocated and included in some practice guidelines. Failure to complete these tests is regarded as patient noncompliance. The purpose of this paper is to review noncompliance with screening tests from the perspective of a traditional biomedical model and an outcomes model. According to the traditional biomedical model, compliance with screening tests is necessary to identify disease at an early stage and to initiate treatment. In contrast, the outcomes model argues that patients and providers should engage in activities that maximize benefit from the patient's perspective. Screening may lead to significant increases in case identification and in treatment rates. However, screening might also identify "pseudodisease," defined as disease that is not clinically important. For some diagnostic tests, cases of pseudodisease far exceed cases of clinically meaningful disease. The outcomes model suggests shared medical decision making in which uncertainties surrounding tests are disclosed to patients. Using information about the risks and expected health outcomes of screening and treatment, patients can participate in decisions about their own health care. Control Clin Trials 2000;21:233S-240S

Assessing the impact of migraine on health-related quality of life: An additional use of the quality of well-being scale-self-administered. Headache 2000; 40:662-71.

Abstract
OBJECTIVES To compare the interviewer-administered Quality of Well-being Scale (QWB) with a self-administered form (QWB-SA) for patients with migraine, and to compare the health status of migraineurs to other medical populations. BACKGROUND With the increasing need to document the cost-effectiveness of treatment for migraine, limitations with both the Medical Outcomes Study Short Form-36 items and the QWB have been an impediment to research using cost-effectiveness as an outcome. Demonstrating the sensitivity of an alternative instrument which addresses these limitations would facilitate cost-effectiveness analyses on treatments for migraine. METHODS Eighty-nine adults (87% women) known to suffer from migraine were asked to complete both the interviewer-administered QWB and the self-administered version (QWB-SA) on three occasions. The first occasion was on a day when no migraine was experienced in the previous 7 days. The second and third assessments were completed within 48 hours of the onset of a migraine. RESULTS While both the QWB and the QWB-SA successfully distinguished migraine from nonmigraine days, more migraines were reported on the QWB-SA. Overall, both instruments showed similar patterns of patient dysfunction during a migraine attack. Each component of the QWB-SA successfully distinguished migraine from nonmigraine days, and the QWB-SA showed a linear sensitivity to pain intensity and disability during a migraine episode. Both instruments are able to detect a migraine's effect on multiple domains of quality of life. Study participants scored significantly lower on the QWB-SA during a migraine episode than several comparison medical populations. CONCLUSIONS The QWB and the QWB-SA appear to have sensitivity to migraine severity, and the ability to quantitate an effect in multiple quality-of-life domains. Both measures can be used to calculate quality-adjusted life-years, thus facilitating cost-effectiveness and health policy work in this important clinical area.

Abstract
BACKGROUND The importance of outcome after major injury has continued to gain attention in light of the ongoing development of sophisticated trauma care systems in the United States. The Trauma Recovery Project (TRP) is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma in adults aged 18 years and older, including quality of life, functional outcome, and psychologic sequelae such as depression and posttraumatic stress disorder (PTSD). Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to describe functional outcomes at the 12-month and 18-month follow-ups in the TRP population and to examine the association of putative risk factors with functional outcome. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the TRP study. The admission criteria for patients were as follows: (1) age 18 years or older; (2) Glasgow Coma Scale score on admission of 12 or greater; and (3) length of stay greater than 24 hours. Functional outcome after trauma was measured before and after injury using the Quality of Well-Being (QWB) Scale, an index sensitive to the well end of the functioning continuum (0 = death, 1.000 = optimum functioning). Follow-up at 12 months after discharge was completed for 806 patients (79%), and follow-up at 18 months was completed for 780 patients (74%). Follow-up contact at any of the study time points (6, 12, or 18 months) was achieved for 926 (88%) patients. RESULTS The mean age was 36 +/- 14.8 years, and 70% of the patients were male; 52% were white, 30% were Hispanic, and 18% were black or other. Less than 40% of study participants were married or living together. The mean Injury Severity Score was 13 +/- 8.5, with 85% blunt injuries and a mean length of stay of 7 +/- 9.2 days. QWB scores before injury reflected the norm for a healthy adult population (mean, 0.810 +/- 0.171). At the 12-month follow-up, there were very high levels of functional limitation (QWB mean score, 0.670 +/- 0.137). Only 18% of patients followed at 12 months had scores above 0.800, the norm for a healthy population. There was no improvement in functional limitation at the 18-month follow-up (QWB mean score, 0.678 +/- 0.130). The majority of patients (80%) at the 18-month follow-up continued to have QWB scores below the healthy norm of 0.800. Postinjury depression, PTSD, serious extremity injury, and intensive care unit days were significant independent predictors of 12-month and 18-month QWB outcome. CONCLUSION This study demonstrates a prolonged and profound level of functional limitation after major trauma at 12-month and 18-month follow-up. This is the first report of long-term outcome based on the QWB Scale, a standardized quality-of-life measure, and provides new and provocative evidence that the magnitude of dysfunction after major injury has been underestimated. Postinjury depression, PTSD, serious extremity injury, and intensive care unit days are significantly associated with 12-month and 18-month QWB outcome.

Abstract
PURPOSE To summarize the development and application of a generic measure of health-related quality of life known as the Quality of Well-Being Scale (QWB). BACKGROUND The QWB is part of a general health policy model. The measure includes functional components for mobility, physical activity, and social activity. In addition, it includes a comprehensive list of symptoms and problems. QWB scoring allows placement of each individual on a continuum of wellness ranging from 0 (for dead) to 1.0 for asymptomatic full function. The General Health Policy Model combines this point in time measure with information on prognosis and mortality to estimate quality-adjusted life-years (QALYs). Forming a ratio of program costs to QALYs yields estimates of cost per quality-adjusted life year. Evidence supports the validity of the QWB for a wide variety of applications in population monitoring, descriptive studies of patient populations, and clinical trials. We offer a variety of comparisons between the QWB and Medical Outcomes Study Short Form 36 (SF-36). MAIN FINDINGS In comparison with the SF-36, the QWB provides less information on health profiles, but has the advantage of providing a metric that can be used for cost-utility or cost-effectiveness analysis. Although ceiling effects are common for some SF-36 subscales, perfect scores on the QWB are very rare. The QWB has an approximately normal distribution for populations of adults. Although, often criticized for not including a mental health component, we present evidence documenting the validity of the QWB for patients with psychological and psychiatric diagnoses. CONCLUSIONS The QWB and SF-36 are alternative comprehensive measures of health outcomes.

Abstract
BACKGROUND The study of both short-term and long-term outcomes after major trauma has become an increasingly important focus of injury research because of the improved survival rates attributable to the evolution of sophisticated trauma care systems. The Trauma Recovery Project (TRP) is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma in adults aged 18 years and older, including quality of life, functional outcome, and psychologic sequelae such as depression and posttraumatic stress disorder (PTSD). Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to describe functional outcomes at the discharge and 6-month follow-up time points in the TRP population and to examine the association of putative risk factors with functional outcome. METHODS Between December 1, 1993, and September 1, 1996, 1,048 eligible trauma patients triaged to four participating trauma center hospitals in the San Diego Regionalized Trauma System were enrolled in the TRP study. The admission criteria for patients were as follows: (1) age 18 years or older, (2) Glasgow Coma Scale score on admission of 12 or greater, and (3) length of stay greater than 24 hours. Functional outcome after trauma was measured before and after injury using the Quality of Well-Being (QWB) scale, a more sensitive index to the well end of the functioning continuum (range, 0 = death to 1.000 = optimum functioning). Functional outcome was also measured using a standard activities of daily living (ADL) scale (range, 13 = full function to 47 = maximum dysfunction). Follow-up at 6 months after discharge was completed for 826 patients (79%). RESULTS The mean age was 36 +/- 14.8 years; 70% of the patients were male; 52% of the patients were white, 30% were Hispanic, and 18% were black or other. Less than 40% of study participants were married or living with a partner. The mean Injury Severity Score was 13 +/- 8.5, with 85% blunt injuries, and a mean length of stay of 7 +/- 9.2 days. QWB scores before injury reflected the norm for a healthy adult population (mean, 0.810 +/- 0.171). After major trauma, QWB scores at discharge showed a significant degree of functional limitation (mean, 0.401 +/- 0.045). At 6-month follow-up, QWB scores continued to show high levels of functional limitation (mean, 0.633 +/- 0.122). Limitation measured using the standard ADL scale found only moderate dysfunction at discharge (mean, 30.0 +/- 7.7) and at 6-month follow-up (mean, 15.0 +/- 4.2). Postinjury depression, PTSD, serious extremity injury, and length of stay were significant independent predictors of 6-month QWB outcome. CONCLUSION Postinjury functional limitation is a clinically significant complication in trauma patients at discharge and a 6-month follow-up. The QWB yields a more sensitive assessment of functional status than traditional ADL instruments. Postinjury depression, PTSD, serious extremity injury, and length of stay are significantly associated with 6-month QWB outcome.

Abstract
PURPOSE To evaluate how well a rapid, self-report of the costs of illness correlates with health-related quality of life. METHODS A total of 211 patients, participating in a clinical trial of an arthritis medication, completed a Quality of Well-being scale interview and an 18-item self-assessment of healthcare utilization. Subjects completed both these instruments at each of three time points during the trial. RESULTS Correlations between the measures and across time suggest that patient-reported costs are associated with quality of life and function. CONCLUSIONS A self-reported cost of illness measure may provide valuable information. With the increase move to assess cost as well as health outcomes, such rapid self-report techniques may prove useful to health services researchers, healthcare system managers, and clinicians.

Abstract
Changes in natural killer cell (NK) activity and proportions of circulating T and NK lymphocyte subsets were assessed in adult males immediately after exposure to controllable or uncontrollable stress (noise) as well as 24 and 72 h later, in order to track the time course of the effects of stress. The role of control-relevant personality variables as moderators of the stress-immunosuppression relationship was considered. Subjects who perceived they had control over the noise as well as no-noise "control" subjects showed no reduction in NK activity. By contrast, subjects who perceived that they had no control over the stressor showed reduced NK activity immediately after the conclusion of the first 20-min stress session, and the reduced NK activity was found as long as 72 h later. Optimism and one's desire to be in control enhanced the negative impact of uncontrollable noise on NK activity. No differences between conditions were found on number of NK cells or a variety of T cell subsets. The results suggest the importance of perceived control in moderating the short- and long-term effects of stress on NK activity.

Abstract
The present study examined the relationship between depression and a constellation of pain-related variables that describe the experience of chronic pain patients. Thirty-seven depressed and 32 non-depressed heterogeneous chronic pain patients were identified through structured interviews, use of standardized criteria and scores on the Beck Depression Inventory (BDI). The 2 groups were compared on demographic variables and scores on the Marlowe-Crowne Social Desirability scale (MC), as well as measures of disability and medication use, pain severity, interference due to pain and reported pain behaviors. The depressed group was found to be younger and to score lower on the MC than the non-depressed group. Multivariate analyses of covariance (MANCOVA), using age and MC as covariates, revealed that depressed chronic pain patients, relative to their non-depressed counterparts, reported greater pain intensity, greater interference due to pain and more pain behaviors. There were no group differences on the measures of disability and use of medications. The results provide further support for the importance of incorporating depression into clinical and theoretical formulations of chronic pain. Future use of structured interviews and standardized criteria for diagnosing depression may clarify some of the inconsistencies found in the literature.
