The present study investigated the validity of the two-factor solution of items selected from the Rumination Scale of the Response Style Questionnaire proposed by Treynor, Gonzalez, and Nolen-Hoeksema (2003). In the first part of this study we used samples of currently depressed (MDD), formerly depressed (FD), socially anxious (SP), and healthy control participants to examine whether the brooding and reflective pondering components differentiate participants with an anxiety disorder from participants with depression. In the second part of this study we examined whether these components of rumination were differentially related to cognitive biases in depression. Overall, the MDD group exhibited higher brooding scores than did all other groups; SP and FD groups did not differ from each other but obtained higher brooding scores than did the control participants. Only the MDD and the control groups differed on the reflective pondering factor. Importantly, brooding and reflective pondering were differentially related to cognitive biases. Specifically, the correlation between brooding/reflective pondering and memory bias was not significant when depressive symptoms were partialed out. The correlation between brooding and attentional bias for sad faces, however, remained significant even when current depressive symptoms were taken into account. In sum, our results support the formulation that rumination is composed of an adaptive reflective pondering factor and a maladaptive brooding factor.

Previous reports suggest that massive hormonal changes that accompany the peripartum period may trigger perinatal depression. We investigated the relationship between magnitude of change and total level of estrogen and progesterone and grade of peripartal depression and depressive symptoms. One hundred and ninety two women were assessed in the 38th week of pregnancy (SDS scores), peripartum period (DSM-III-R diagnosis (n=105); SDS scores) and 6 months postpartum (EPDS; n=89) regarding diagnosis of depression, self-ratings of depressive symptoms and levels of estrogen and progesterone. The comparison of three diagnostic groups (lifetime major depressive disorder MDD (N=7), MDD at birth (N=12), healthy controls (N=70) showed that there were no differences in the magnitude of decline of estrogen and progesterone from day 1 to day 3 after birth . With respect to total levels of estrogen and progesterone, estrogen on day 3 was significantly higher [F(2,92)=6.6, p<0.05] in women with current MDD than in those with lifetime MDD or normal controls. Depression scores were significantly higher at the end of pregnancy (12.6% self-identified as depressed) than in postpartum period (5.8% day 3 p<.0004; 9.2% day 5 p<.008), whereas 13.3% of women received a DSM-III -R diagnosis for MDD 5 days postpartum. The results were in contrast to the current hypotheses of estrogen withdrawal or hypogonadal levels as an etiological factor for peripartum depression. But a limitation of the actual study is the low number of subjects with depression; therefore the current non-significant findings should be interpreted with great caution.

The studies of maxillofacial gunshot injuries mainly focused on evaluating the surgical interventions and physical outcomes of the procedures. In this study we aimed to analyze the pre- and post-injury psychiatric status of the patients with self-inflicted gunshot wounds to the face. This study is based on 12 subjects who attempted suicide resulting in extensive maxillofacial injuries using guns placed beneath their chins. The psychiatric evaluation was conducted by interview and using SCID-I, SCID-II, MMPI, Rosenberg Self-Esteem Scale and Suicide Probability Scale. Two subjects were healthy, 1 had bereavement, 6 had current and 5 had previous MDD (major depressive disorder), 2 had dysthymic disorder, 3 had alcohol abuse, 2 had drug abuse and 4 had antisocial personality disorder. The suicidal group was more socially introverted according to MMPI. According to Rosenberg self-esteem subscale, self esteem, the constancy of self respect and depressive mood subtests were statistically significant in the suicide group compared to the healthy controls (P < 0.01). Depressive spectrum disorders are the most common causes. It is obvious that untreated or undiagnosed depression may increase risk of committing suicide. The changes in the physical facial appearance after the suicide attempt caused impairment of self-esteem and the constancy of self-respect. Similar to other studies, none of our patients reattempted suicide and all tried to return to their pre-injury lifestyle and appeared to accommodate to the stigma of their physical deformities. Early diagnosis and treatment should be considered as a factor to reduce the risk for suicide attempt.

Dependency and self-criticism have been proposed as personality dimensions that confer vulnerability to depression. In this study we set out to investigate the diagnostic specificity of these personality dimensions and their relationship with gender differences, severity of depression, and specific depressive symptoms. Levels of dependency and self-criticism as measured by the Depressive Experiences Questionnaire (DEQ) were compared among patients with major depressive disorder (MDD; n=93), mixed psychiatric patients (n=43), university students (n=501), and community adults (n=253). Associations with severity of depression and specific depressive symptoms were also explored. Results showed that dependency was more specifically associated with MDD, whereas self-criticism did not differ between depressed and mixed psychiatric patients. In line with the gender incongruence hypothesis, women with MDD and other psychiatric disorders had higher levels of self-criticism compared to men, whereas men with MDD had higher levels of dependency compared to women. Severity of depression was more clearly linked to self-criticism than to dependency, particularly in patients with MDD. Finally, both dependency and self-criticism were related to theoretically predicted clusters of depressive symptoms, especially after we controlled for shared variance between self-critical and dependent symptoms, respectively. Limitations of this study include the cross-sectional design, which limited the ability to draw causal conclusions. In addition, this study relied exclusively on self-reported personality and mood. Overall, findings of this study suggest that both dependency and self-criticism are associated with MDD, severity of depression, and specific depressive symptoms, and that gender-incongruent personality traits may be associated with increased risk for depression and other disorders.

The purpose of this study was to examine conjoint trajectories of depression-physical illness in elderly medical inpatients with heart failure and/or chronic pulmonary disease and major depression (MDD), and to identify baseline predictors of trajectory. Consecutive medically hospitalized patients over age 50 with heart failure and/or chronic pulmonary disease were screened for MDD using the Structured Clinical Interview for Depression. Patients were re-evaluated at 6, 12, 18, and 24 weeks. Four depression-physical illness conjoint trajectories were examined: depression better, illness better; depression better, illness same; depression same, illness better; and depression same, illness same. Baseline predictors of trajectory were examined. MDD was identified in 413 patients; 352 had at least one follow-up. By 6 weeks, 22.3% improved on both depression and illness and 38.1% improved on neither. By 24 weeks, 45.0% had improved on both and 24.8% on neither. Short-term baseline predictors of trajectory (6 weeks) differed from long-term (12-24 weeks); past psychiatric history, overall medical illness severity, and education were short-term predictors, whereas past psychiatric history, depression treatments, and physical functioning were long-term. Improvements in MDD and physical illness track closely together. Characteristics during baseline hospitalization predict outcome trajectory after discharge, and may be useful in understanding etiology and directing treatment.

Depression frequently is comorbid with a variety of medical illnesses; individuals who have such comorbidities may have increased morbidity and lower functional status. Usual antidepressant treatments can be effective in depressed patients who have comorbid medical illness. These patients, however, experience lower rates of recovery and remission of depressive symptoms and higher rates of relapse during follow-up than seen in patients who have MDD with no medical comorbidity. Comorbid medical illness therefore is a marker of treatment resistance in MDD. Collaborative treatments combining antidepressants, psychotherapy, education, and case management may be effective and could overcome the risk of treatment resistance. Two clinical strategies seem warranted in light of the studies presented here: (1) an increased index of suspicion for depression in medically ill patients, and (2) more intensive antidepressant treatment in depressed patients who have medical comorbidity.

The goal of this study was to compare neural activation patterns in patients with PTSD with and without current comorbid major depression. Traumatized subjects with PTSD (n=11), PTSD+major depression (MDD, n=15), and subjects (n=16) who met criterion A for PTSD but never developed the disorder were studied using the script-driven symptom-provocation paradigm adapted to functional magnetic resonance imaging (fMRI) at a 4-Tesla field strength. Both the PTSD+MDD and PTSD-MDD groups revealed decreased brain activation in the anterior cingulate gyrus (BA 24) and the right ventrolateral prefrontal cortex (BA 47). After covariation for differences in PTSD severity between these groups, the left insula (BA 13) remained more significantly activated in the PTSD-MDD group than in the PTSD+MDD group. In contrast, the PTSD+MDD group showed greater activation than the PTSD-MDD group in the bilateral anterior cingulate gyrus (BA 24) and posterior cingulate cortices (BA 23, 31). These results suggest different patterns of brain activation related to comorbid major depression occurring in the context of PTSD.

We sought to examine the effects of age, depression chronicity, and treatment responsiveness on glucose metabolism in a large well-characterized sample of depressed men and a psychiatrically unaffected control group. The subjects were unmedicated, symptomatic, right-handed males (n=66) who met DSM-IV criteria for a major depressive episode in the context of a major depressive disorder (MDD, n=66) and never depressed, right-handed, healthy control subjects (HC, n=24). Subjects in the MDD group were subsequently classified as responders, or non-responders to a six-week trial of paroxetine monotherapy (20-60 mg). Statistical parametric mapping (SPM) was used to analyze the relationship between age and cerebral glucose metabolism (18-fluorodeoxyglucose positron emission tomography) and the modulation by treatment responsivity and a history of prior depressive episodes. Metabolic activity in the rostral and dorsal anterior cingulate cortex showed a significant negative correlation with age in MDD, but not in HC. Non-response to treatment and previous depressive episodes were associated with a higher degree of age-dependent hypometabolism in the rostral and anterior cingulate cortex. The age-dependent changes documented herein may influence the distinct clinical presentation and treatment response described in older-age depression.

Co-occurring psychiatric disorders have been associated with poor prognosis among substance-dependent patients, but few studies have examined this association among patients with cocaine dependence (CD). We compared baseline characteristics and treatment outcome between cocaine-dependent patients with major depressive disorder (MDD; n = 66), those with attention-deficit/hyperactivity disorder (ADHD; n = 53), and those with CD without comorbid disorders (CD alone; n = 48) who had been randomized to the placebo arms of clinical trials with venlafaxine, methylphenidate, and gabapentin, respectively. The three groups differed significantly in racial makeup, with more Caucasians and Hispanics among patients with MDD and those with ADHD but more African Americans among those with CD alone. The groups did not differ significantly in treatment retention, with retention rates ranging from 42% to 47%; neither did they differ in the rates of achieving 2 consecutive weeks of urinalysis-confirmed abstinence, with rates ranging from 40% to 50%. Using logistic regression for repeated measures with general estimating equations, modeling the likelihood of a cocaine-positive week over time in treatment, we found the diagnostic group to interact with the baseline level of cocaine use and time. Among cocaine-dependent patients who achieved abstinence at baseline, those with MDD and those with ADHD had better outcome over time as compared with patients with CD alone. However, among patients with cocaine-positive urine specimens at baseline, those with MDD and those with ADHD were associated with poor outcome as compared with patients with CD alone. The findings suggest that diagnosis and treatment of co-occurring disorders such as depression and ADHD may be important components of treatment planning for CD and that the baseline level of cocaine use should be included as a covariate in studies evaluating the impact of such treatment.

MDD and anxiety disorders are highly prevalent among persons who have MS and have been associated with decreased adherence to MS treatment and poorer functional status and quality of life. Effective treatment is available for MDD, but this disorder continues to be underdetected and undertreated by MS providers. Treatment with pharmacotherapy is particularly challenging in this patient population, given the somatic symptom overlap between MS and depression and the increased burden of side effects. Larger randomized, controlled trials are needed to elucidate further the effectiveness of pharmacotherapy and to identify subgroups of patients who would benefit from this type of treatment for depression. There have been few rigorous studies of the prevalence and impact of anxiety disorders, substance use disorders, or serious mental illness such as bipolar disorder or schizophrenia, in MS samples.
