Background
Despite its popularity, little is known about the measurement invariance of the Patient Health Questionnaire‐9 (PHQ‐9) across U.S. sociodemographic groups. Use of a screener shown not to ...possess measurement invariance could result in under/over‐detection of depression, potentially exacerbating sociodemographic disparities in depression. Therefore, we assessed the factor structure and measurement invariance of the PHQ‐9 across major U.S. sociodemographic groups.
Methods
U.S. population representative data came from the 2005–2016 National Health and Nutrition Examination Survey (NHANES) cohorts. We conducted a measurement invariance analysis of 31,366 respondents across sociodemographic factors of sex, race/ethnicity, and education level.
Results
Considering results of single‐group confirmatory factor analyses (CFAs), depression theory, and research utility, we justify a two‐factor structure for the PHQ‐9 consisting of a cognitive/affective factor and a somatic factor (RMSEA = 0.034, TLI = 0.985, CFI = 0.989). On the basis of multiple‐group CFAs testing configural, scalar, and strict factorial invariance, we determined that invariance held for sex, race/ethnicity, and education level groups, as all models demonstrated close model fit (RMSEA = 0.025–0.025, TLI = 0.985–0.992, CFI = 0.986–0.991). Finally, for all steps ΔCFI was <−0.004, and ΔRMSEA was <0.01.
Conclusions
We demonstrate that the PHQ‐9 is acceptable to use in major U.S. sociodemographic groups and allows for meaningful comparisons in total, cognitive/affective, and somatic depressive symptoms across these groups, extending its use to the community. This knowledge is timely as medicine moves towards alternative payment models emphasizing high‐quality and cost‐efficient care, which will likely incentivize behavioral and population health efforts. We also provide a consistent, evidence‐based approach for calculating PHQ‐9 subscale scores.
Abstract Cross-sectional studies have found that individuals with depressive disorders or symptoms have elevated levels of inflammatory markers predictive of coronary artery disease, including ...interleukin-6 (IL-6) and C-reactive protein (CRP). Due to the paucity of prospective studies, however, the directionality of the depression–inflammation relationship is unclear. We evaluated the longitudinal associations between depressive symptoms and both IL-6 and CRP among 263 healthy, older men and women enrolled in the Pittsburgh Healthy Heart Project, a 6-year prospective cohort study. During the baseline and follow-up visits, participants completed the Beck Depression Inventory-II (BDI-II) to assess depressive symptoms and underwent blood draws to quantify serum IL-6 and CRP. Path analyses revealed that baseline BDI-II ( β = 0.18, p = 0.01, ΔR2 = 0.02) was a predictor of 6-year change in IL-6, even after adjustment for demographic, biomedical, and behavioral factors as well as other negative emotions. Of all the factors examined, only body-mass index was a stronger predictor of IL-6 change than depressive symptoms. In contrast to these results, baseline IL-6 did not predict 6-year change in BDI-II. Evidence of a weak bidirectional relationship between BDI-II and CRP was also observed; however, neither of these longitudinal associations was significant. The present findings indicate that depressive symptoms may precede and augment some inflammatory processes relevant to coronary artery disease among healthy, older adults. Therefore, our results imply that depression may lead to inflammation and that inflammation may be one of the mechanisms through which depression contributes to cardiovascular risk.
Although patient–provider language concordance has the potential to reduce health disparities for people with limited English proficiency, no previous work has synthesized this literature. Our ...systematic review sought to describe the characteristics of studies examining relationships between language concordance and health outcomes, summarize the nature of observed associations, and propose an evidence map and research agenda. A comprehensive search of published articles identified 38 quantitative studies for inclusion. Most studies were cross-sectional, conducted in primary care, concentrated in Western states, and focused on Spanish speakers and physician providers. Results were split between supporting a positive association versus no association of language concordance with patient behaviors, provider behaviors, interpersonal processes of care, and clinical outcomes. Several methodological limitations were identified. Based on these results, we developed an evidence map, identified knowledge gaps, and proposed a research agenda. There is a particular need for quasi-experimental longitudinal studies with well-characterized samples.
Abstract Objective We investigated whether number of recent stressful life events is associated with incident cardiovascular disease (CVD) and whether this relationship is stronger in adults with a ...history of clinical depression. Methods Prospective data from 28,583 U.S. adults (mean age = 45 years) initially free of CVD who participated in Waves 1 (2001–2002) and 2 (2004–2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined. Number of past-year stressful life events (Wave 1), lifetime depressive disorder (Wave 1), and incident CVD (Wave 2) were determined by structured interviews. Results There were 1069 cases of incident CVD. Each additional stressful life event was associated with a 15% increased odds of incident CVD Odds Ratio ( OR ) = 1.15, 95% Confidence Interval ( CI ): 1.11, 1.19. As hypothesized, a stressful life events by lifetime depressive disorder interaction was detected ( P = 0.003). Stratified analyses indicated that stressful life events had a stronger association with incident CVD among adults with ( OR = 1.18, 95% CI : 1.10, 1.27, n = 4908) versus without ( OR = 1.10, 95% CI : 1.07, 1.14, n = 23,675) a lifetime depressive disorder. Conclusion Our findings suggest that a greater number of recent stressful life events elevate the risk of new-onset CVD and that this risk is potentiated in adults with a history of clinical depression.
One might expect that the provision of integrated cardiovascular care—an approach that treats people as more than their biology; that spans primary, secondary, and tertiary prevention; and that is ...consistent with our understanding of behavioral and psychosocial factors as major drivers of chronic disease burden— would be the norm. This is clearly not the case, and this fact served as our central motivation for assembling this Special Issue of Health Psychology. The response to the Special Issue announcement as represented by the papers published here reflect where cardiovascular behavioral medicine (CVBM) has been, where our field needs to go, and how we might get there. We see needs (a) to expand our research beyond the epidemiologic and mechanistic studies that have dominated the field and to refocus our science on the design, testing, and implementation of integrated interventions and health care delivery models; (b) to fully integrate CVBM patient care into holistic, team-based cardiovascular care, which will require a louder voice and a place at the table with institutions and organizations that formulate health care reimbursement policies; and (c) to create new models of clinical and research training to develop a workforce that is well prepared to achieve these visions of CVBM research and patient care. Here, we elaborate on our view of these needs, identify barriers to realizing these visions, and discuss paths forward in science, patient care, and training to maximize the impact of cardiovascular behavioral medicine.

Considerable epidemiologic evidence and plausible biobehavioral mechanisms suggest that depression is an independent risk factor for diabetes. Moreover, reducing the elevated diabetes risk of ...depressed individuals is imperative given that both conditions are leading causes of death and disability. However, because no prior study has examined clinical diabetes outcomes among depressed patients at risk for diabetes, the question of whether depression treatment prevents or delays diabetes onset remains unanswered. Accordingly, we examined the effect of a 12-month collaborative care program for late-life depression on 9-year diabetes incidence among depressed, older adults initially free of diabetes. Participants were 119 primary care patients M (SD) age: 67.2 (6.9) years, 41% African American with a depressive disorder but without diabetes enrolled at the Indiana sites of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) trial. Incident diabetes cases were defined as diabetes diagnoses, positive laboratory values, or diabetes medication prescription, and were identified using electronic medical record and Medicare/Medicaid data. Surprisingly, the rate of incident diabetes in the collaborative care group was 37% (22/59) versus 28% (17/60) in the usual care group. Even though the collaborative care group exhibited greater reductions in depressive symptom severity (p = .024), unadjusted (HR = 1.29, 95% CI: 0.69-2.43, p = .428) and adjusted (HR = 1.18, 95% CI: 0.61-2.29, p = .616) Cox proportional hazards models indicated that the risk of incident diabetes did not differ between the treatment groups. Our novel preliminary findings raise the possibility that depression treatment alone may be insufficient to reduce the excess diabetes risk of depressed, older adults.

Although depression is a risk and prognostic factor for cardiovascular disease (CVD), depression trials involving cardiac patients have not observed the anticipated cardiovascular benefits. To test ...our hypothesis that depression treatment delivered before clinical CVD onset reduces risk of CVD events, we conducted an 8-year follow-up study of the Indiana sites of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) randomized controlled trial.
Participants were 235 primary care patients 60 years or older with major depression or dysthymia who were randomized to a 12-month collaborative care program involving antidepressants and psychotherapy (85 without and 35 with baseline CVD) or usual care (83 without and 32 with baseline CVD). Hard CVD events (fatal/nonfatal) were identified using electronic medical record and Medicare/Medicaid data.
A total of 119 patients (51%) had a hard CVD event. As hypothesized, the treatment × baseline CVD interaction was significant (p = .021). IMPACT patients without baseline CVD had a 48% lower risk of an event than did usual care patients (28% versus 47%, hazard ratio = 0.52, 95% confidence interval = 0.31-0.86). The number needed to treat to prevent one event for 5 years was 6.1. The likelihood of an event did not differ between IMPACT and usual care patients with baseline CVD (86% versus 81%, hazard ratio = 1.19, 95% confidence interval, 0.70-2.03).
Collaborative depression care delivered before CVD onset halved the excess risk of hard CVD events among older, depressed patients. Our findings raise the possibility that the IMPACT intervention could be used as a CVD primary prevention strategy.

Although the Hispanic population is a burgeoning ethnic group in the United States, little is known about their pain-related experience. To address this gap, we critically reviewed the existing ...literature on pain experience and management among Hispanic Americans (HAs). We focused our review on the literature on nonmalignant pain, pain behaviors, and pain treatment seeking among HAs. Pain management experiences were examined from HA patients' and health care providers' perspectives. Our literature search included variations of the term "Hispanic" with "AND pain" in PubMed, Embase, Web of Science, ScienceDirect, and PsycINFO databases. A total of 117 studies met our inclusion criteria. We organized the results into a conceptual model with separate categories for biological and/or psychological and sociocultural and/or systems-level influences on HAs' pain experience, response to pain, and seeking and receiving pain care. We also included information on health care providers' experience of treating HA patients with pain. For each category, we identified future areas of research. We conclude with a discussion of limitations and clinical implications.
In this critical review of the literature we examined the pain and management experiences of the HA population. We propose a conceptual model, which highlights findings from the existing literature and future areas of research.
