Dysfunctional attitudes are mood-state dependent.

To test the hypothesis that self-report of dysfunctional attitudes is mood-state dependent, dysfunctional attitudes were assessed in 43 women before and after they received a depressed or elated mood induction. As predicted, the mood induction produced reliable changes in mood and in dysfunctional attitudes, although the increase in dysfunctional attitudes following the negative mood induction was not large enough to be statistically significant. We also tested the hypothesis, from the cognitive theory of depression, that subjects with previous episodes of depression would report more dysfunctional attitudes than would subjects without such a history. As predicted, subjects who reported previous episodes of depression endorsed more dysfunctional attitudes than did subjects who did not report such a history. However, this effect occurred only for subjects who were in a negative mood state when their dysfunctional attitudes were assessed. These findings support the proposition of the cognitive theory that dysfunctional attitudes are traits but suggest that these traits are mood-state dependent.

Cognitive–behavioral treatment for depression in smoking cessation.

Cigarette smokers with past major depressive disorder (MDD) received 8 group sessions of standard, cognitive–behavioral smoking cessation treatment (ST; n?=?93) or standard, cognitive–behavioral smoking cessation treatment (ST) plus cognitive–behavioral treatment for depression (CBT-D; n?=?86). Although abstinence rates were high in both conditions (ST, 24.7%; CBT-D, 32.5%, at 1 year) for these nonpharmacological treatments, no main effect of treatment was found. However, secondary analyses revealed significant interactions between treatment condition and both recurrent depression history and heavy smoking (≥25 cigarettes a day) at baseline. Smokers with recurrent MDD and heavy smokers who received CBT-D were significantly more likely to be abstinent than those receiving ST (odds ratios?=?2.3 and 2.6, respectively). Results suggest that CBT-D provides specific benefits for some, but not all, smokers with a history of MDD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Life events and depression in adolescence: Relationship loss as a prospective risk factor for first onset of major depressive disorder.

Although stressful life events have consistently been linked to the onset of major depressive disorder (MDD), most research has not distinguished 1st episodes from recurrences. In a large epidemiologic: sample of older adolescents (N?=?1,470) assessed at 2 time points, the risk conferred by a recent romantic break-up was examined as a predictor of 1st onset versus recurrence of MDD. Results indicated a heightened likelihood of 1st onset of MDD during adolescence if a recent break-up had been reported; in contrast, a recent break-up did not predict recurrence of depression. These results held for both genders and remained significant after controlling for gender. Additional analyses to determine the discriminant validity and specificity of these findings strongly supported the recent break-up as a significant risk factor for a 1st episode of MDD during adolescence. Implications of these findings and subsequent research directions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influences of Mood, Depression History, and Treatment Modality on Outcomes in Smoking Cessation.

The relationship between major depressive disorder (MDD), treatment modality, and mood was evaluated in smokers participating in cessation programs. Participants (N = 549, 53.7% women, 46.3% men, 28% endorsing past MDD episodes) were randomly assigned to a cognitive-behavioral treatment (CBT) or health education (HE) intervention. Participants with a history of recurrent MDD (MDD-R) had higher rates of abstinence in CBT compared with HE even when the contribution of mood and the interaction between mood and an MDD × Treatment variable were included in the model. Likewise, higher levels of mood disturbance were reported by MDD-R smokers compared with those reporting a single episode. The study replicated results reported by R. A. Brown et al. (2001) and expanded upon them by evaluating the differential contribution of poor mood on cessation outcomes relative to MDD history.

Primary early-onset dysthymia: Comparison with primary nonbipolar nonchronic major depression on demographic, clinical, familial, personality, and socioenvironmental characteristics and short-term outcome.

In order to explore the characteristics and validity of DSM-III-R primary early-onset dysthymia, we compared outpatients with primary early-onset dysthymia (n?=?32) and primary nonbipolar nonchronic major depression (n?=?35). Fifty-nine percent of the dysthymics were currently in a major depressive episode, and 97% had a history of major depression. Compared with the episodic major depressives, the early-onset dysthymics exhibited significantly higher rates of melancholia, greater global impairment, and an earlier age of onset of major depression; were more likely to have recurrent major depressive episodes; and had higher rates of personality and substance use disorders. In addition, significantly higher proportions of early-onset dysthymics than nonchronic major depressives had family histories of affective and antisocial personality disorders. The dysthymics also exhibited significantly higher levels of depressive personality traits and self-criticism, lower levels of extraversion and social support, and higher levels of chronic strain and perceived stress than did the major depressives. Finally, the early-onset dysthymics exhibited significantly greater depression and poorer social and global functioning over the course of a 6-month follow-up.

Congruence of personality and life events in depression.

Consistent with the personality–event congruence hypothesis, highly sociotropic depressed patients (n?=?19) reported more recent negative interpersonal events than negative autonomy events and more negative interpersonal events than did highly autonomous depressed patients (n?=?22), for whom the hypothesis was not supported. There was no evidence of such congruence among nondepressed schizophrenic patients (n?=?44). In a 2nd study, there was significant personality–event congruence in dysphoric students (n?=?26) but not in nondysphoric students (n?=?56). Both the high-sociotropy and high-autonomy dysphoric groups separately yielded nonsignificant trends consistent with congruence. These findings add to the growing support for the importance of the sociotropy construct in depression and weaker support for the autonomy construct or its measurement, and they suggest that the congruence effect does not generalize to all psychopathologies.

A prospective study of stress autonomy versus stress sensitization in adolescents at varied risk for depression.

This longitudinal study investigated the stress autonomy, stress sensitization, and depression vulnerability hypotheses in adolescents across 6 years (i.e., Grades 6 through 12). Participants were 240 children (Time 1 mean age = 11.86, SD = 0.57) who varied in risk for depression on the basis of their mother's history of mood disorders. All analyses were conducted as multilevel models to account for nesting in the data. Results were consistent with the stress sensitization hypothesis. The within-subject relation of stress levels to depressive symptoms strengthened with increasing numbers of prior depressive episodes. In addition, evidence consistent with the vulnerability hypothesis was found. The relation of stress levels to depressive symptoms was stronger for adolescents who were at risk for depression on the basis of maternal depression history and for those who had experienced more depressive episodes through Grade 12. These findings suggest that onsets of depression in adolescents may be predicted by both relatively stable and dynamic transactions between stressful life events and vulnerabilities such as maternal depression and youths' own history of depressive episodes.

Major depressive disorder: a prospective study of residual subthreshold depressive symptoms as predictor of rapid relapse

BACKGROUND: The study tested whether level of recovery from major depressive episodes (MDEs) predicts duration of recovery in unipolar major depressive disorder (MDD) patients. METHODS: MDD patients seeking treatment at five academic centers were followed naturalistically for 10 years or longer. Patients were divided on the basis of intake MDE recovery into residual depressive symptoms (SSD; N=82) and asymptomatic (N=155) recovery groups. They were compared on time to first episode relapse/recurrence, antidepressant medication, and comorbid mental disorders. Recovery level was also compared to prior history of recurrent MDEs ( > 4 lifetime episodes) as a predictor of relapse/recurrence. RESULTS: Residual SSD compared to asymptomatic recovery patients relapsed to their next MDE > 3 times faster (median=68 vs. 23 weeks) and to any depressive episode > 5 times faster (median=33 vs. 184 weeks). Residual SSD recovery status was significantly associated with early episode relapse (OR=3.65) and was stronger than history of recurrent MDEs (OR=1.64). Rapid relapse in the SSD group could not be attributed to higher comorbidity or lower antidepressant treatment. LIMITATIONS: Although inter-rater agreement on weekly depressive symptom ratings was very high (ICC > 0.88), some error may exist in assigning recovery levels. Antidepressant treatments were recorded, but were not controlled. CONCLUSIONS: MDE recovery is a powerful predictor of time to episode relapse/recurrence. Residual SSD recovery is associated with very rapid episode relapse which supports the idea that SSD is an active state of illness. Asymptomatic recovery is associated with prolonged delay in episode recurrence. These findings of this present study have important implications for the goals of treatment of MDD and for defining true MDE recovery.     

Family group cognitive–behavioral preventive intervention for families of depressed parents: 18- and 24-month outcomes.

Objective: In a long-term follow-up of a randomized controlled trial (Compas et al., 2009) to examine the effects at 18- and 24-month follow-ups of a family group cognitive–behavioral (FGCB) preventive intervention for mental health outcomes for children and parents from families (N = 111) of parents with a history of major depressive disorder (MDD). Method: Parents with a history of MDD and their 9- to 15-year-old children were randomly assigned to a FGCB intervention or a written information comparison condition. Children's internalizing, externalizing, anxiety/depression, and depressive symptoms; episodes of MDD and other psychiatric diagnoses; and parents' depressive symptoms and episodes of MDD were assessed at 18 and 24 months after randomization. Results: Children in the FGCB condition were significantly lower in self-reports of anxiety/depression and internalizing symptoms at 18 months and were significantly lower in self-reports of externalizing symptoms at 18 and 24 months. Rates of MDD were significantly lower for children in the FGCB intervention over the 24-month follow-up (odds ratio = 2.91). Marginal effects were found for parents' symptoms of depression at 18 and 24 months but not for episodes of MDD. Conclusions: Support was found for a FGCB preventive intervention for children of parents with a history of MDD significantly reducing children's episodes of MDD over a period of 2 years. Significant effects for the FGCB intervention were also found on internalizing and externalizing symptoms, with stronger effects at 18- than at 24-month follow-up.

Predicting response to depression treatment: The role of negative cognition.

Repeated experiences with major depressive disorder (MDD) may strengthen associations between negative thinking and dysphoria, rendering negative cognition more accessible and pronounced with each episode. According to cognitive theory, greater negative cognition should lead to a more protracted episode of depression. In this study of 121 adults with MDD, number of previous episodes was associated with slower change in depression across inpatient and outpatient treatment. Further, although pretreatment negative cognition and pretreatment family impairment both uniquely predicted slower change in depressive symptoms, only negative cognition mediated the association between depression history and depression change. Findings suggest that repeated MDD episodes are specifically associated with increased negative cognition, which in turn contributes to a more pernicious course of symptom change during treatment for depression.

Personality disorders in adolescents with major depression, substance abuse disorders, and coexisting major depression and substance use disorders.

This study examined the presence of personality disorders in adolescent inpatients with major depression (MDD; n?=?45), substance use disorders (SUD; n?=?27), or both disorders combined (MDD-SUD; n?=?42). A consecutive series of patients were given structured diagnostic interviews for Axes I and II disorders. The groups did not differ with regard to age, gender, ethnicity, socioeconomic status, psychiatric history, or global assessment of functioning. Borderline personality disorder was diagnosed more frequently in the MDD-SUD group than in the MDD or SUD groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

New minimal substrate structural requirements in the enzymatic peroxidation of alkenes with soybean lipoxygenase

A longitudinal study was conducted to investigate the association between human immunodeficiency virus (HIV) infection, history of major depressive disorder (MDD), and persistent or recurrent MDD among intravenous drug users. Psychiatric disorders were assessed in a sample of HIV-positive (HIV+) and HIV-negative (HIV-) intravenous drug users every 6 months for 3 years. Results indicated that HIV status and baseline MDD independently predicted persistent or recurrent episodes of MDD after gender, drug use, ethnicity, income, and the presence other psychiatric disorders were controlled statistically. Among HIV+ intravenous drug users with baseline MDD, 90% experienced at least one subsequent episode of MDD and 47% experienced at least three subsequent episodes of MDD. However, less than 40% of intravenous drug users with current MDD received treatment for emotional problems. These findings indicate that intravenous drug users with HIV infection and a history of MDD are at considerable risk for future episodes of MDD or recurrent MDD, and that increased provision of treatment for intravenous drug users with MDD may be necessary.     

Sex dfferences in the relation of mood to weight gain after quitting smoking.

Weight gain with smoking cessation is well documented. In this study the authors explored the impact of mood state on weight gain after quitting. Data of 350 participants enrolled in 2 smoking cessation trials were analyzed; primary analyses assessed the relation of affective factors to weight gain in abstinent participants only. Weight gain was predicted by abstinence status. Depression history, gender, and mood change from pre- to postcessation assessments were included in a model predicting weight gain in abstinent participants at the end of smoking cessation treatment (N?=?201) and at 1-year follow-up (N?=?87). At posttreatment, depression history positive women gained more than depression negative women, whereas depression history positive men gained less than depression history negative men. At 1-year follow-up, weight gain was predicted by improved mood in "normal" men and by worsened mood in both depression history positive and negative women.

Recurrence of MDD: A prospective study of personality pathology and cognitive distortions.

Major depressive disorder (MDD) is characterized by a high risk of recurrence, especially among individuals whose initial episode occurs during adolescence. Identifying predictors of recurrence of MDD among young samples is therefore of paramount clinical importance. Survival analytic models were used to evaluate the effects of dysfunctional cognitions and Axis II personality pathology on MDD recurrence in a sample of 130 previously, but not currently, depressed young adults. Participants were initially assessed for depression, dysfunctional attitudes, and personality pathology during their first semester in college and then reevaluated via the Longitudinal Interval Follow-up Evaluation interview every 6 months for 18 months. Baseline level of depressive symptoms significantly (HR-1.07, p = .002) predicted recurrence of MDD. In the survival analyses with baseline level of depression serving as a current mood state covariate, overall personality pathology (HR-1.04, p DSM–IV personality disorder cluster scores uniquely predicted recurrence. We discussed the theoretical, empirical, and clinical implications of these findings, and we noted the limitations of the study. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

A prospective 12-year study of subsyndromal and syndromal depressive symptoms in unipolar major depressive disorders

BACKGROUND: Investigations of unipolar major depressive disorder (MDD) have focused primarily on major depressive episode remission/recovery and relapse/recurrence. This is the first prospective, naturalistic, long-term study of the weekly symptomatic course of MDD. METHODS: The weekly depressive symptoms of 431 patients with MDD seeking treatment at 5 academic centers were divided into 4 levels of severity: (1) depressive symptoms at the threshold for MDD; (2) depressive symptoms at the threshold for minor depressive or dysthymic disorder (MinD); (3) subsyndromal or subthreshold depressive symptoms (SSDs), below the thresholds for MinD and MDD; and (4) no depressive symptoms. The percentage of weeks at each level, number of changes in symptom level, and medication status were analyzed overall and for 3 subgroups defined by mood disorder history. RESULTS: Patients were symptomatically ill in 59% of weeks. Symptom levels changed frequently (1.8/y), and 9 of 10 patients spent weeks at 3 or 4 different levels during follow-up. The MinD (27%) and SSD (17%) symptom levels were more common than the MDD (15%) symptom level. Patients with double depression and recurrent depression had more chronic symptoms than patients with their first lifetime major depressive episode (72% and 65%, respectively, vs 46% of follow-up weeks). CONCLUSION: The long-term weekly course of unipolar MDD is dominated by prolonged symptomatic chronicity. Combined MinD and SSD level symptoms were about 3 times more common (43%) than MDD level symptoms (15%). The symptomatic course is dynamic and changeable, and MDD, MinD, and SSD symptom levels commonly alternate over time in the same patients as a symptomatic continuum of illness activity of a single clinical disease.     

Validity and efficiency of screening for history of depression by self-report.

Because of the recurrent nature of depression, there is a need for a rapid means of screening for history of depression that is either valid in itself or an efficient means of identifying respondents needing further assessment. This study examined the validity and efficiency of assessment of lifetime history of depression by self-report screening questions in comparison with the results of a structured interview assessment conducted a year earlier. Self-reported lifetime 2-week mood disturbance was unrelated to the results of the earlier interview. Self-report of treated episodes of mood disturbance were related to interview-assessed history of depression, but too modestly for practical applications. Self-report of past depression was more strongly related to concurrent distress than to the earlier interview assessment of history of depression. Implications of these findings for screening and assessment of history of depression are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mood and depression diagnosis in smoking cessation.

The history of major depressive disorder (MDD), mood at baseline and during quitting, and abstinence at 2 and 52 weeks in 62 smoking treatment patients were examined. Of these participants, 44% were positive for a history of MDD. Depressive history participants had more anger and less vigor at baseline and greater increases in anger and depression during quitting than those without a history. There were significant interactive effects of baseline mood by depression history in predicting abstinence at Week 2 but not at Week 52. Participants with a depression history and who reported greater depression, fatigue, and anger at baseline had lower 2-week abstinence rates than those without a depression history, although not significantly. Participants with a depression history and who reported less depression, fatigue, and anger at baseline had higher 2-week abstinence rates than those without a depression history, although not significantly. Baseline-to-quitting increases in depression were negatively related to 2-week abstinence. Mood during quitting was not significantly related to abstinence at either week.

Comorbidity of unipolar depression: I. Major depression with dysthymia.

The degree of current and lifetime comorbidity between major depressive disorder (MDD) and dysthymia (DY) was examined in large community samples of older adolescents (n?=?1,710) and adults (n?=?2,060). DY was highly comorbid with MDD (lifetime odds ratio of 3.4 for adolescents and 1.6 for adults) and was more likely to precede than to follow MDD, especially in persons who became depressed early in life. MDD was by far the more frequent form of depression: Approximately 80% of the depressed persons experienced only MDD, 10% experienced only DY, and 10% experienced both MDD and DY. The large number of persons who had become depressed twice experienced MDD in the 2nd episode, regardless of the nature of the 1st depression. History of depression was associated with a greater probability for other mental disorders in both adolescents and adults; however, the rates of comorbidity for MDD did not differ from rates for DY or for both MDD and DY.

Dysphoria and social interaction: an integration of behavorial confirmation and interpersonal perspectives

To investigate the process by which dysphoric persons are rejected by others, authors integrated behavioral confirmation and interpersonal theories of depression. The expectations of nondysphoric perceiver participants (college students) were manipulated, such that half expected to interact with a same-sex dysphoric target and half expected to interact with a same-sex nondysphoric target. The targets' actual mood status was consistent or inconsistent with these expectations. Pre- and postinteraction impressions, as well as postinteraction acceptance of partners, were solicited from perceivers and targets (N = 240). Audiotaped verbal behaviors were coded during the 1st and last 3 min of the interactions. Acceptance of targets and verbal behaviors were an interactive function of perceivers' expectancies and targets' mood status, such that dysphoric targets who were expected to be nondysphoric were the least accepted group and had the most dysfunctional interactions.
