Socioeconomic status, depression disparities, and financial strain: What lies behind the income‐depression relationship?
Prior studies have consistently found the incidence and persistence of depression to be higher among persons with low incomes, but causal mechanisms for this relationship are not well understood. This study uses the National Longitudinal Survey of Youth 1979 cohort to test several hypotheses about the robustness of the depression–income relationship among adults. In regressions of depression symptoms on income and sociodemographic variables, inco…

Theoretical ideas regarding the relatively high comorbidity rates are presented along with a model describing putative interactions between anxiety disorders and asthma. METHOD: A search of the literature from the last 2 decades using MEDLINE by pairing the word, "asthma," with the following words: "anxi…
Influence of Patient Attachment Style on Self-care and Outcomes in Diabetes
OBJECTIVE: Difficulties collaborating with providers and important others may adversely influence self-management in patients with diabetes. We predicted that dismissing attachment style, characterized by high interpersonal self-reliance and low trust of others, would be associated with poorer self-management in patients with diabetes. METHODS: A population-based mail survey was sent to all patients with diabetes from nine primary care clinics of…
Appraised changeability of a stressor as a modifier of the relationship between coping and depression: A test of the hypothesis of fit
The goodness of fit among the appraised changeability of a stressor, coping, and depression in people with psychiatric, physical health, work, and family problems was examined (N = 746). It was expected that problem-focused coping (as opposed to emotion-focused coping) would be used more and be more adaptive in situations appraised as changeable as compared with situations appraised as not changeable. Although few relationships existed between ap…

Improving Services for Women with Depression in Primary Care Settings
Women have a higher prevalence of depressive disorders compared to men. The current system of care for women with depressive disorders provides significant financial barriers for patients with lower incomes to access mental health services. Primary care systems are used extensively by women and have the potential to diagnose patients at early stages of mental illness and to provide evidence-based treatments, but this potential is largely unfulfil…
Depression and somatization: A review
Responses to illness and health in chronic pain patients and healthy adults
Although it is clear that health care utilization rates differ among individuals, what is not so obvious is the explanation for the variation in illness responses, nor is it known whether responses to illness are consistent or predictable. This pilot study compared responses to common symptoms and health maintenance activities in 1) healthy subjects with no medical visits in the previous year, 2) patients with chronic headaches with high medical …

Medical and psychiatric symptoms in women with childhood sexual abuse
Although there is increasing awareness of the short-term psychological and social adaptations to childhood sexual abuse, little is known about the long-term effects of such abuse, particularly its effect on subsequent medical utilization and the experience and reporting of physical symptoms. We re-analyzed data from a previous study of 100 women scheduled for diagnostic laparoscopy (50 for chronic pain, 50 for tubal ligation or infertility evalua…
Adequacy and Duration of Antidepressant Treatment in Primary Care
Among a sample of 119 distressed high-utilizers of primary care, 45% of patients evaluated by a psychiatrist as needing antidepressant treatment had been treated in the year before the examination. However, only 11% of the patients needing antidepressants had received adequate dosage and duration of pharmacotherapy. In the year following the intervention, study patients whose physicians were advised regarding treatment during a psychiatric consul…

OBJECTIVES. The purposes of this study were to (1) characterize the social disability associated with the common psychiatric illnesses of primary care patients in terms of role dysfunction (self-care, family role, social role, occupational role) and (2) establish whether severity of psychiatric illness and disability level show synchrony of change. METHODS. A two-stage sample design was employed. In the first stage, 1994 consecutive attenders of …
Methodologic issues in randomized trials of liaison psychiatry in primary care
Most anxiety, depressive, and substance abuse disorders are treated exclusively in the primary care health system. However, recognition and treatment of these disorders in primary care is deficient. Psychopharmacologic and psychotherapeutic interventions have been developed and proven effective in randomized trials in specialty care. However, the results of successful trials of mental health interventions in specialty settings may not generalize …

Attachment Theory: A Model for Health Care Utilization and Somatization
Objective Attachment theory proposes that cognitive schemas based on earlier repeated experiences with caregivers influence how individuals perceive and act within interpersonal relationships. We hypothesized that medical patients with two types of insecure attachment—preoccupied and fearful attachment—would have higher physical symptom reporting compared with those with other attachment styles, but that preoccupied attachment would be associated…
Cost-Effectiveness of a Program to Prevent Depression Relapse in Primary Care
OBJECTIVE: Evaluate the incremental cost-effectiveness of a depression relapse prevention program in primary care. MATERIALS AND METHODS: Primary care patients initiating antidepressant treatment completed a standardized telephone assessment 6-8 weeks later. Those recovered from the current episode but at high risk for relapse (based on history of recurrent depression or dysthymia) were offered randomization to usual care or a relapse prevention …
Depression and Pain Comorbidity: A Literature Review
Because depression and painful symptoms commonly occur together, we conducted a literature review to determine the prevalence of both conditions and the effects of comorbidity on diagnosis, clinical outcomes, and treatment. The prevalences of pain in depressed cohorts and depression in pain cohorts are higher than when these conditions are individually examined. The presence of pain negatively affects the recognition and treatment of depression. …
