Altered temporal, but intact spatial, features of transient network dynamics in psychosis.

Contemporary models of psychosis suggest that a continuum of severity of psychotic symptoms exists, with subthreshold psychotic experiences (PEs) potentially reflecting some genetic and environmental risk factors shared with clinical psychosis. Thus, identifying abnormalities in brain activity that manifest across this continuum can shed new light on the pathophysiology of psychosis. Here, we investigated the moment-to-moment engagement of brain networks ("states") in individuals with schizophrenia (SCZ) and PEs and identified features of these states that are associated with psychosis-spectrum symptoms. Transient brain states were defined by clustering "single snapshots" of blood oxygen level-dependent images, based on spatial similarity of the images. We found that individuals with SCZ (n = 35) demonstrated reduced recruitment of three brain states compared to demographically matched healthy controls (n = 35). Of these three illness-related states, one specific state, involving primarily the visual and salience networks, also occurred at a lower rate in individuals with persistent PEs (n = 22), compared to demographically matched healthy youth (n = 22). Moreover, the occurrence rate of this marker brain state was negatively correlated with the severity of PEs (r = -0.26, p = 0.003, n = 130). In contrast, the spatial map of this state appeared to be unaffected in the SCZ or PE groups. Thus, reduced engagement of a brain state involving the visual and salience networks was demonstrated across the psychosis continuum, suggesting that early disruptions of perceptual and affective function may underlie some of the core symptoms of the illness.

Increased amygdala-visual cortex connectivity in youth with persecutory ideation.

BACKGROUND: Subclinical delusional ideas, including persecutory beliefs, in otherwise healthy individuals are heritable symptoms associated with increased risk for psychotic illness, possibly representing an expression of one end of a continuum of psychosis severity. The identification of variation in brain function associated with these symptoms may provide insights about the neurobiology of delusions in clinical psychosis. METHODS: A resting-state functional magnetic resonance imaging scan was collected from 131 young adults with a wide range of severity of subclinical delusional beliefs, including persecutory ideas. Because of evidence for a key role of the amygdala in fear and paranoia, resting-state functional connectivity of the amygdala was measured. RESULTS: Connectivity between the amygdala and early visual cortical areas, including striate cortex (V1), was found to be significantly greater in participants with high (n = 43) v. low (n = 44) numbers of delusional beliefs, particularly in those who showed persistence of those beliefs. Similarly, across the full sample, the number of and distress associated with delusional beliefs were positively correlated with the strength of amygdala-visual cortex connectivity. Moreover, further analyses revealed that these effects were driven by those who endorsed persecutory beliefs. CONCLUSIONS: These findings are consistent with the hypothesis that aberrant assignments of threat to sensory stimuli may lead to the downstream development of delusional ideas. Taken together with prior findings of disrupted sensory-limbic coupling in psychosis, these results suggest that altered amygdala-visual cortex connectivity could represent a marker of psychosis-related pathophysiology across a continuum of symptom severity.

Sex Differences in the Association between Heavy Drinking and Behavioral Distress Tolerance and Emotional Reactivity Among Non-Depressed College Students.

BACKGROUND: Heavy episodic drinking (HED) is a common behavior among college students that is associated with severe negative consequences. Negative reinforcement processes have been applied to elucidate mechanisms underlying relationships between consumption of alcohol and the desire to alleviate negative feelings. Distress tolerance (DT) and emotional reactivity are two mechanisms that are consistent with the self-medication model that may contribute to HED. The current study investigated relationships between DT, emotional reactivity, defined as frustration reactivity and irritability reactivity, and HED in a non-depressed college population. Given differential patterns of consumption and motivation for drinking between males and females, sex differences were also examined. SHORT SUMMARY: The study examined two constructs consistent with negative reinforcement processes, behavioral distress tolerance (DT) and emotional reactivity (frustration reactivity and irritability reactivity), to explain heavy episodic drinking (HED) among non-depressed college students. Behavioral DT and frustration reactivity independently predicted HED. Higher HED was associated with higher frustration reactivity and lower behavioral DT in women, but nor in men. METHODS: One-hundred-ten college students without depressive symptoms completed alcohol use measures and the Paced Auditory Serial Attention Task (PASAT-C) to assess behavioral DT and emotional reactivity. RESULTS: DT and frustration reactivity independently predicted HED. The association between DT and HED was moderated by sex such that higher levels of DT predicted higher HED among females, but not among males. Higher frustration reactivity scores were associated with a greater number of HED. CONCLUSIONS: Results provide supporting evidence that DT and emotional reactivity are distinct factors, and that they predict HED independently. Results underscore the importance of examining sex differences when evaluating the association between HED and negative reinforcement processes in this population.

Similar changes in cognitions following cognitive-behavioral therapy or escitalopram for major depressive disorder: Implications for mechanisms of change.

BACKGROUND: Psychosocial treatments and medications both have been shown to be effective in treating major depressive disorder. We hypothesized that cognitive-behavioral therapy (CBT) would outperform medication on measures of cognitive change. METHODS: We randomized depressed individuals to 12 weeks of CBT (n = 15) or escitalopram (n = 11). In an intent-to-treat analysis (n = 26), we conducted a repeated measures analysis of variance to examine changes in depressive symptoms (ie, 17-item Hamilton Depression Rating Scale, Beck Depression Inventory), anhedonia (ie, Snaith-Hamilton Pleasure Scale), cognitive measures (ie, Dysfunctional Attitudes Scale, Automatic Thoughts Questionnaire, Perceived Stress Scale), and quality of life (ie, Quality of Life Enjoyment and Satisfaction Questionnaire) at 4 time points: baseline, week 4, week 8, and week 12. Treatment for both groups started at baseline, and patients received either 12 weeks of individual CBT or 12 weeks of escitalopram with flexible dosing (10 to 20 mg). RESULTS: Collapsing the escitalopram and CBT groups, there were statistically significant pre-post changes on all outcome measures. However, there were no statistically significant differences between treatment groups on any of the outcome measures, including cognitive measures across time points. CONCLUSIONS: Our results suggest that both CBT and escitalopram have similar effects across a variety of domains and that, in contrast to our a priori hypothesis, CBT and escitalopram were associated with comparable changes on cognitive measures.

College students with depressive symptoms with and without fatigue: Differences in functioning, suicidality, anxiety, and depressive severity.

BACKGROUND: We examined whether fatigue was associated with greater symptomatic burden and functional impairment in college students with depressive symptoms. METHODS: Using data from the self-report Beck Depression Inventory (BDI), we stratified a group of 287 students endorsing significant symptoms of depression (BDI score ≥ 13) into 3 levels: no fatigue, mild fatigue, or moderate/severe fatigue. We then compared the 3 levels of fatigue across a battery of psychiatric and functional outcome measures. RESULTS: Approximately 87% of students endorsed at least mild fatigue. Students with moderate/severe fatigue had significantly greater depressive symptom severity compared with those with mild or no fatigue and scored higher on a suicide risk measure than those with mild fatigue. Students with severe fatigue evidenced greater frequency and intensity of anxiety than those with mild or no fatigue. Reported cognitive and functional impairment increased significantly as fatigue worsened. CONCLUSIONS: Depressed college students with symptoms of fatigue demonstrated functional impairment and symptomatic burden that worsened with increasing levels of fatigue. Assessing and treating symptoms of fatigue appears warranted within this population.

Relationship between sleep disturbance and depression, anxiety, and functioning in college students.

BACKGROUND: Sleep disturbance (SD) has complex associations with depression, both preceding and following the onset and recurrence of depression. We hypothesized that students with depressive symptoms with SD would demonstrate a greater burden of comorbid psychiatric symptoms and functional impairment compared to students with depressive symptoms without SD. METHODS: During a mental health screening, 287 undergraduate students endorsed symptoms of depression (Beck Depression Inventory [BDI] ≥ 13) and filled out the following self-report measures: demographic questionnaire, BDI, Anxiety Symptom Questionnaire-intensity and frequency (ASQ), Beck Hopelessness Scale (BHS), Beck Anxiety Inventory (BAI), Quality of Life Enjoyment and Satisfaction Questionnaire (QLESQ), and the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ). SD was measured using the BDI sleep item #16 dichotomized (score 0: no SD; or score > 0: some SD). RESULTS: Students with depressive symptoms and SD (n = 220), compared to those without SD (n = 67), endorsed significantly more intense and frequent anxiety and poorer cognitive and physical functioning. Students with depressive symptoms with and without SD did not significantly differ in depressive severity, hopelessness, or quality of life. CONCLUSIONS: College students with depressive symptoms with SD may experience a greater burden of comorbid anxiety symptoms and hyperarousal, and may have impairments in functioning, compared to students with depressive symptoms without SD. These findings require replication.

Factors that distinguish college students with depressive symptoms with and without suicidal thoughts.

BACKGROUND: Suicide among college students is a significant public health concern. Although suicidality is linked to depression, not all depressed college students experience suicidal ideation (SI). The primary aim of this study was to determine potential factors that may distinguish college students with depressive symptoms with and without SI. METHODS: A total of 287 undergraduate college students with substantial depressive symptoms (Beck Depression Inventory [BDI] total score >13) with and without SI were compared across psychiatric and functional outcome variables. Independent sample t tests were conducted for each outcome variable using the suicide item of the BDI as a dichotomous (ie, zero vs nonzero score) grouping variable. RESULTS: Relative to students with substantial depressive symptoms without SI, those with SI were more symptomatic overall, having significantly higher levels of depressive symptoms, hopelessness, and anxiety. However, contrary to our expectations, nonsuicidal and suicidal students did not differ on measures of everyday functioning (ie, cognitive and physical functioning and grade point average). CONCLUSIONS: Our findings suggest that SI among college students is associated with increased subjective distress but may not adversely impact physical or cognitive functioning or academic performance.

Correlates of irritability in college students with depressive symptoms.

Depression is a prevalent psychiatric disorder associated with significant personal and societal burden. There is accumulating evidence for the presence of a subtype of depression characterized by the presence of irritability that is associated with increased morbidity, risk for suicidal ideation, and functional impairments in adults. Little is known about the features of depressive symptoms with and without irritability among young adults in college. The primary aim of this study was to characterize the presentation of college students with depressive symptoms and irritability. Two-hundred eighty-seven undergraduate college students with depressive symptoms with and without irritability were compared across several psychiatric and functional outcome variables. Independent samples t-tests or logistic regressions were conducted for each outcome variable using the irritability item of the Beck Depression Inventory as a dichotomous grouping variable. Analyses were conducted separately for the men and the women. Both male and female students with depressive symptoms and severe irritability reported a greater severity of depressive symptoms compared with their peers with no or mild irritability. In the women, the presence of irritability was associated with greater symptoms of anxiety, whereas in the men, it was associated with increased likelihood of engaging in risky behaviors, including compulsive use of alcohol, illicit drugs, and prescription drugs. The male and female college students with depressive symptoms with and without irritability did not differ on severity of suicidal ideation, hopelessness, or cognitive functioning. The findings from this study suggest that depressive symptoms and irritability may characterize a subtype of college students who have a greater symptom burden and with the potential need for more aggressive and prompt treatment.

Prevalence of MTHFR C677T and MS A2756G polymorphisms in major depressive disorder, and their impact on response to fluoxetine treatment.

OBJECTIVE: To examine the prevalence of the C677T polymorphism of the methylene tetrahydrofolate reductase (MTHFR) gene and the A2756G polymorphism of methionine synthase (MS), and their impact on antidepressant response. METHODS: We screened 224 subjects (52% female, mean age 39 ± 11 years) with SCID-diagnosed major depressive disorder (MDD), and obtained 194 genetic samples. 49 subjects (49% female, mean age 36 ± 11 years) participated in a 12-week open clinical trial of fluoxetine 20-60 mg/day. Association between clinical response and C677T and A2756G polymorphisms, folate, B12, and homocysteine was examined. RESULTS: Prevalence of the C677T and A2756G polymorphisms was consistent with previous reports (C/C = 41%, C/T = 47%, T/T = 11%, A/A = 66%, A/G = 29%, G/G = 4%). In the fluoxetine-treated subsample (n = 49), intent-to-treat (ITT) response rates were 47% for C/C subjects and 46% for pooled C/T and T/T subjects (nonsignificant). ITT response rates were 38% for A/A subjects and 60% for A/G subjects (nonsignificant), with no subjects exhibiting the G/G homozygote. Mean baseline plasma B12 was significantly lower in A/G subjects compared to A/A, but folate and homocysteine levels were not affected by genetic status. Plasma folate was negatively associated with treatment response. CONCLUSION: The C677T and A2756G polymorphisms did not significantly affect antidepressant response. These preliminary findings require replication in larger samples.

The absence of depressive symptoms is not the presence of wellness: validation of the Clinical Positive Affect Scale.

OBJECTIVE: Many patients with depression respond or remit with current treatments, but often experience persistent distress, in part because they perceive that they have not returned to their normal or premorbid state. Some continue to have a lack of subjective psychological well-being and positive affect following treatment. It would be useful to measure these deficits and explore whether interventions can improve them. Currently, no clinically useful scale has been developed to measure positive affect. To fill this gap, we developed the Clinical Positive Affect Scale (CPAS). METHOD: The purpose of this study is to describe the development and validation of the CPAS, a 16-item self-report measurement of self-perceived affective and cognitive correlates of positive affect, in a sample of 300 college students. RESULTS: A principal component analysis with varimax rotation showed one major factor of positive affect, with all items revealing high loadings (≥ 0.65) on the single factor. The CPAS also demonstrated good internal consistency (α = 0.97) and strong part-whole correlations. Finally, the CPAS revealed some degree of divergent validity through moderately strong negative correlations with validated measures of depression, anxiety and drug abuse. CONCLUSIONS: This study supports the validity of the CPAS, which may help clinicians and researchers to assess patients' current self-perceived levels of hedonic capacity and enthusiasm for life.

Depression and suicidal ideation in college students.

BACKGROUND/AIMS: Suicide is one of the leading causes of death in college students and is often associated with depression. The aim of this study was to assess the rates of suicidal ideation (SI) on college campuses and to identify its correlates. METHODS: On-campus depression screening sessions were conducted at 3 universities (n = 898; 55% female; mean age 20.07 ± 1.85 years). Participants completed the Beck Depression Inventory (BDI; mean ± SD of total score = 6.27 ± 6.31) and other measures. Eighty-four students endorsed a '1' on the BDI suicidality item, suggesting thoughts of suicide. RESULTS: Results showed that students with greater depression severity, higher levels of hopelessness, and poorer quality of life were more likely to endorse SI. CONCLUSION: Factors associated with SI highlighted in this study may aid in the identification of college students at risk for suicide.

Diminished frontal pole size and functional connectivity in young adults with high suicidality.

BACKGROUND: Suicide rates among young people have been increasing in recent years, yet no validated methods are available for identifying those who are at greatest risk for suicide. Abnormalities in the medial prefrontal cortex have been previously observed in suicidal individuals, but confounding factors such as treatment and chronic illness may have contributed to these findings. Thus, in this study we tested whether the size of the medial prefrontal cortex is altered in suicidal young adults who have received no treatment with psychotropic medications. METHODS: Suicidality was evaluated using the Suicide Behaviors Questionnaire-Revised (SBQ-R) and surface areas of four regions-of-interest (ROIs) within the medial prefrontal cortex were measured using magnetic resonance imaging (MRI) in a cohort of college students (n = 102). In addition, a secondary seed-based functional connectivity analysis was conducted using resting-state functional MRI data. Areas and functional connectivity of the medial prefrontal cortex of young adults with high suicidality (HS; SBQ-R score > 7; n = 20) were compared to those with low suicidality (LS; SBQ-R score = 3, n = 37). RESULTS: Compared to the LS group, the HS group had a significantly lower surface area of the right frontal pole (p < 0.05, Bonferroni-corrected) and significantly lower functional connectivity of the right frontal pole with the bilateral inferior frontal cortex (p < 0.001, Monte-Carlo corrected). LIMITATION: These findings require replication in a larger sample and extension in younger (adolescent) populations. CONCLUSION: Diminished frontal pole surface area and functional connectivity may be linked to elevated levels of suicidality in young people.

Relationships among subclinical psychotic symptoms in young adults over time.

BACKGROUND: Subclinical psychotic symptoms are common in the general population and are often benign. However, those that become distressing or persistent may increase risk for the development of a psychotic disorder. Cognitive models have proposed that certain appraisals of hallucinatory experiences can lead to delusional beliefs, particularly if an individual is experiencing negative mood. However, the dynamic relationships among these symptoms are poorly understood. This study examined the longitudinal relationships among subclincal hallucinations, delusional ideation, and depression in a sample of young adults. METHODS: 677 college students completed baseline questionnaires to assess: delusional ideation (Peters Delusions Inventory), hallucinations (Launay-Slade Hallucinations Scale-Extended), and depression (Beck Depression Inventory). These measures were repeated 7, 13, 19, and 25 months later. RESULTS: Higher baseline severity of hallucinations was strongly predictive of severity of delusions across all future follow-up timepoints, specifically when baseline depression was high. However, the severity of hallucinations did not change over time, nor were they predicted by baseline delusional ideation. CONCLUSIONS: These findings support the proposal that hallucinations frequently precede more severe delusional ideation, rather than the reverse sequence, particularly when depressive symptoms are present. Such longitudinal relationships provide clues to the underlying mechanisms of psychosis, highlighting one pathway for intervention.

Assessing depression and factors possibly associated with depression during the course of Parkinson's disease.

BACKGROUND: Although research suggests depression is common among individuals with Parkinson's disease (PD), it is unclear how to best assess depression in PD (dPD). We wanted to examine the prevalence of dPD using different definitions of depression, as well as examine factors associated with dPD. METHODS: One hundred fifty-eight individuals (68% male; age 66.8 ± 9.6 SD) with a primary diagnosis of PD were assessed for depression using the Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS) in an outpatient setting at the Movement Disorders Clinic at Massachusetts General Hospital. We defined depression using 4 thresholds based on the HANDS and whether or not an individual was ever on an antidepressant regimen. We also examined potential predictors of the presence of dPD. RESULTS: The prevalence of depression among study participants ranged from 11% to 57%, depending on which of the 4 definitions of depression was applied. Younger age and longer duration of PD predicted a relatively higher prevalence of depression. Having a history of depression prior to onset of PD also was predictive of dPD. CONCLUSIONS: Depression appears to be relatively common among individuals with PD, and history of depression, younger age, and longer PD duration may be factors associated with dPD.

Compulsive alcohol use and other high-risk behaviors among college students.

The association between heavy alcohol consumption and risky behaviors has been amply investigated among college students. However, less is known with regard to types of drinking behaviors associated with high-risk activities. The present study extends this area of research by examining the relationship between compulsive drinking and hazardous behaviors in this population. Nine hundred and four college students completed measures on compulsive drinking and other risky behaviors in the context of mental health screenings at three campuses. Results showed that in males, compulsive drinking increased the risk for compulsive street drugs use, compulsive prescription drugs use, compulsive sexual activities, and gambling. Among females, compulsive drinking increased the risk for compulsive street drugs use, and compulsive sexual activities. These findings suggest that inquiring about compulsive drinking among college students may have great utility in identifying those at greater risk for other risky behaviors. The high co-occurrence of compulsive drinking, illicit substances, compulsive sexual activities, and gambling in college students suggests the need for comprehensive programs addressing high-risk behaviors together.

Gender, depressive symptoms and patterns of alcohol use among college students.

BACKGROUND: Serious alcohol-related negative consequences are associated with a number of drinking behaviors among college students. Thus, it is critical to identify students who are at greater risk for hazardous drinking. Although some studies have shown that depressive symptoms may be associated with alcohol use in this population, findings are not consistent. The current study extends previous research by investigating the relationship between depressive symptoms, daily alcohol use and compulsive drinking among college students and whether gender moderates these relationships. SAMPLING AND METHODS: The participants were 904 college students (495 females; mean age = 20.07 ± 1.85 years) who filled out questionnaires that focused on drinking behaviors and severity of depressive symptoms. RESULTS: Gender moderated the relationship between depressive symptoms and daily alcohol consumption. In male college students, worse depressive symptoms were associated with increased daily alcohol use and with greater risk for compulsive drinking. In female college students, worse depressive symptoms increased the risk for compulsive drinking, but not for greater daily alcohol use. CONCLUSIONS: Results suggest that prevention programs aimed at decreasing harmful alcohol use among college students must take into consideration the role of both gender and depressive symptoms in the development of problematic drinking behaviors.

Anxious attachment is associated with heightened responsivity of a parietofrontal cortical network that monitors peri-personal space.

BACKGROUND: Attachment, or affiliative bonding among conspecifics, is thought to involve neural mechanisms underlying behavioral responses to threat and reward-related social signals. However, attachment-oriented responses may also rely on basic sensorimotor processes. One sensorimotor system that may play a role in attachment is the parietofrontal cortical network that responds to stimuli that are near or approaching the body, the peripersonal space (PPS) monitoring system. We hypothesized that this network may vary in responsivity to such potentially harmful stimuli, particularly those with social salience, based on individual differences in attachment styles. METHODS: Young adults viewed images of human faces or cars that appeared to move towards or away from them, while functional magnetic resonance imaging data were collected. Correlations between each of four adult attachment styles, measured using the Relationship Questionnaire, and responses of the PPS network to approaching (versus withdrawing) stimuli were measured. RESULTS: A region-of-interest (ROI) analysis, focused on six cortical regions of the PPS network that showed significant responses to approaching versus withdrawing face stimuli in an independent sample (n = 80), revealed that anxious attachment style (but not the other 3 attachment styles) was significantly positively correlated with responses to faces (but not to cars) in all six ROIs (r = 0.33-0.49, p = 0.01-0.0001, n = 50). CONCLUSIONS: These findings suggest that anxious attachment is associated with over-responsivity of a sensorimotor network involved in attending to social stimuli near the body.

Relationship between cannabis use and psychotic experiences in college students.

BACKGROUND: Emerging data suggest cannabis use is a component cause of psychotic disorders; however, the sequence of processes accounting for this association is poorly understood. Some clues have come from studies in laboratory settings showing that acute cannabis intoxication is associated with subclinical hallucinations and delusional thinking, i.e., "psychotic experiences". Although psychotic experiences are relatively common, those that are severe and distressing are linked to an increased risk of developing a psychotic disorder. This study aimed to investigate the association between the frequency of cannabis use and psychotic experiences in young adults. METHODS: 1034 U.S. college students completed questionnaires to assess: cannabis use in the past week, delusional ideation (Peters Delusions Inventory), hallucinations (Launay-Slade Hallucinations Scale-Extended), and depression (Beck Depression Inventory). RESULTS: Participants reporting higher rates of weekly cannabis use were more likely to report hallucinatory experiences and delusional ideation. The relationship between cannabis use and hallucinatory experiences, but not the relationship between cannabis use and delusional ideation, remained significant after controlling for levels of depression. Moreover, those who reported greater amounts of cannabis use had more distressing delusional ideas, that were held with more conviction. CONCLUSIONS: Cannabis use is linked to the presence of subclinical hallucinations and delusional ideation in U.S. college students.

Early improvements in anxiety, depression, and anger/hostility symptoms and response to antidepressant treatment.

BACKGROUND: The purpose of this study was to examine whether treatment response to fluoxetine by depressed outpatients was predicted by early improvement on any of 3 subscales (Anxiety, Depression, and Anger/Hostility) of the Symptom Questionnaire (SQ). METHODS: We evaluated 169 depressed outpatients (52.6% female) between ages 18 and 65 (mean age, 40.3 +/- 10.6 years) meeting DSM-IIIR criteria for major depressive disorder (MDD). All patients completed the SQ at baseline (week 0) and at weeks 2, 4, and 8 of treatment with fluoxetine 20 mg/d. We defined treatment response as a > or= 50% reduction in score on the 17-item Hamilton Rating Scale for Depression, and early improvement on 3 SQ subscales (Anxiety, Depression, and Anger/Hostility) as a >30% reduction in score by week 2. RESULTS: The percentage of patients with significant early improvement in anger was significantly greater than the percentage of those with early improvements in anxiety or depression. When early improvement on the Anxiety, Depression, and Anger/Hostility subscales of the SQ were assessed independently by logistic regression, all 3 subscales were predictors of response to treatment. CONCLUSIONS: Early improvement in anger, anxiety, and depressive symptoms may predict response to antidepressant treatment among outpatients with MDD.

Health-related quality of life in depression: a STAR*D report.

BACKGROUND: Although major depressive disorder (MDD) is associated with significant impairments in health-related quality of life (HRQOL), few studies have evaluated HRQOL dysfunction in multiple domains. This report examined the psychological, physical, and social domains in a large sample of outpatients who entered the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial. METHODS: The relationship of HRQOL and baseline sociodemographic and clinical features, including depressive severity, was evaluated. We assessed HRQOL with the 12-item Short Form Health Survey, the 5-item Work and Social Adjustment Scale, and the 16-item Quality of Life Enjoyment and Satisfaction Questionnaire. RESULTS: Among 2307 participants, greater depressive symptom severity was associated with poorer HRQOL. After controlling for age and depression severity, lower HRQOL was related independently to being African American or Hispanic, less educated, unemployed, divorced or separated, having public medical insurance, and to having more general medical disorders. We found impairments across all 3 domains, with low correlations between the 3 measures of HRQOL chosen, suggesting that they evaluate different and nonoverlapping aspects of function. CONCLUSION: Sociodemographically disadvantaged patients with greater general medical and depressive illness burden are at greatest risk for poorer quality of life. Distinct impairments are seen in the 3 domains of HRQOL.
