Defocused Attention in Depressed Mood: Evidence From Source Monitoring.

The authors suggest that depressed mood is associated with a defocused mode of attention, allowing irrelevant information to be noticed and processed more than in nondepressed states. Working on a source monitoring task, subclinically depressed college students selected with the Beck Depression Inventory (A. T. Beck, 1967; D. Kammer, 1983) had better memory for irrelevant stimulus aspects than nondepressed control students. However, depressed students' performance on the relevant stimulus aspects was unimpaired. These results are in conflict with a capacity reduction view of depressed mood and support the hypothesized altered, defocused mode, in which attentional resources are more evenly allocated across various aspects of the materials. The results are discussed within the framework of adaptive functions of emotional states. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory Accessibility, Mood Regulation, and Dysphoria: Difficulties in Repairing Sad Mood With Happy Memories?

Recent studies have suggested that mood-incongruency effects are due to mood-regulatory processes, in which people retrieve positive memories to repair negative moods. In Study 1, the authors investigated whether dysphoria influences the accessibility of autobiographical memories following a positive or a negative mood induction combined with subsequent rumination or distraction. The results showed a mood-repair effect for nondysphoric but not for dysphoric participants following rumination. In Study 2, participants were asked to either distract themselves or to recall positive autobiographical memories after a negative mood induction. Whereas nondysphoric participants' mood improved under both conditions, dysphoric participants' mood improved only after distraction. These results suggest that dysphoria is associated with a reduced ability to use mood-incongruent recall to repair sad moods. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Mood and personality-based models of substance use.

Mood and personality-based vulnerabilities have been extensively examined in patients with substance use disorders, but their relevance as models of etiology remains to be fully investigated. The present investigation examined mood and personality-based models of substance use in a nonclinical sample of young adults. Two-hundred and twelve individuals were assessed for personality and clinical characteristics and participated in computerized ambulatory monitoring of mood states and substance use over a 1-week period. Personality factors were strong predictors of substance use frequency over the previous 30 days, as well as of substance use in daily life using ambulatory monitoring. A linear increase was also observed in the intensity of novelty seeking and antisocial personality traits as a function of the social deviance of substances used. However, mood disorder history was related only to the use of illicit drugs other than cannabis, and fluctuations in mood states did not prospectively predict daily use of substances in a manner consistent with self-medication. Moreover, there was little evidence that personality characteristics moderated relations between mood states and substance use in daily life. The relevance of results for mood and personality models of substance use etiology is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotion regulation and its effects on mood improvement in response to an in vivo peer rejection challenge.

This study examined children's spontaneous use of behavioral emotion regulation (ER) strategies and their effects on subsequent mood change in response to an in vivo peer rejection manipulation. Participants (N = 186), ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (being voted out of the game) or nonrejection control. In response to rejection, more than one third of the participants (38%) displayed a marked worsening (i.e., reliable change) in state mood. After receiving feedback, time spent on several behavioral ER strategies during a 5-minute postfeedback period was assessed. At the end of the postfeedback period, children's cognitive activity was also assessed. More time spent on behavioral distraction was positively linked to subsequent increases in positive affect, whereas the reverse pattern was found for disengagement/passive behavior. Moreover, higher endorsement ratings for the strategy of "cognitive analysis" were associated with stronger increases in negative affect.

Family functioning in bipolar I disorder.

In a sample of 62 patients with Bipolar I disorder, the authors used a repeated measures longitudinal design to examine whether global family functioning was associated with the presence of a concurrent bipolar episode as well as whether global family functioning was associated with the presence of manic and depressive episodes in the following 3 months. Participants were recruited for a randomized clinical trial examining the efficacy of family treatments combined with pharmacotherapy for bipolar disorder. Global family functioning was repeatedly measured with both clinician-rated and patient-rated assessment instruments over the 28-month study period. Results indicated that mood episodes were associated with concurrent global family functioning within individuals, but global family functioning was not associated with episode status in the subsequent 3 months. The repeated measures nature of these results suggests that global family functioning and bipolar episodes may fluctuate in concert with each other but that global family functioning is not associated with subsequent change in episode status.

Neuroinflammation as a Common Denominator of Complex Diseases (Cancer,Diabetes Type 2, and Neuropsychiatric Disorders)

The term neuroinflammation refers to inflammation of the nervous tissue, in general, and in the central nervous system (CNS), in particular. It is a driver of neurotoxicity, it is detrimental, and implies that glial cell activation happens prior to neuronal degeneration and, possibly, even causes it. The inflammation-like glial responses may be initiated in response to a variety of cues such as infection, traumatic brain injury, toxic metabolites, or autoimmunity. The inflammatory response of activated microglia engages the immune system and initiates tissue repair. Through translational research the role played by neuroinflammation has been acknowledged in different disease entities. Intriguingly, these entities include both those directly related to the CNS (commonly designated neuropsychiatric disorders) and those not directly related to the CNS (e.g., cancer and diabetes type 2). Interestingly, all the above-mentioned entities belong to the same group of “complex disorders”. This review aims to summarize cumulated data supporting the hypothesis that neuroinflammation is a common denominator of a wide variety of complex diseases. We will concentrate on cancer, type 2 diabetes (T2DM), and neuropsychiatric disorders (focusing on mood disorders).     

Social interaction moderates the relationship between depressive mood and heart rate variability: Evidence from an ambulatory monitoring study.

Objective: There is considerable evidence that depressive mood is related to lower parasympathetic control of the heart, thus increasing cardiovascular risk. However, little is known about social factors (e.g., social affiliation) that might moderate this relationship. Design: The authors examined whether cardiac autonomic control in healthy individuals with depressive symptoms could be altered by social interaction. Therefore, the authors conducted a 22-hr ambulatory monitoring study with a sample of 63 adults. Main Outcome Measures: Depression was assessed by questionnaire. Heart rate, heart rate variability (HRV), physical activity, and negative affect were recorded throughout one day via portable monitoring devices. Results and Conclusion: Multilevel analyses revealed that depression was related to elevated negative affect and higher heart rate throughout the day. Moreover, there was a tendency toward lower HRV in individuals with higher depression scores. This association, however, was moderated by social context. When depressive participants were alone they evidenced lower HRV and higher negative affect, but not when they were engaged in social interactions with a partner, family members, or friends. These findings suggest that the relation between depression and cardiac autonomic control could be altered by social interaction, thus possibly buffering adverse health effects.

Elevated positive mood: A mixed blessing for abstinence.

The present study, a secondary analysis of published data (B. Hitsman et al., 1999), assessed (a) the influence of initial positive mood (PM) on smoking cessation and (b) whether smokers low in PM benefited from fluoxetine versus placebo for cessation. Euthymic adult smokers (N = 103) received 10 weeks of cessation treatment. Analyses showed a Time × PM interaction, indicating that higher baseline PM predicted decreased abstinence during treatment but increased abstinence afterward, mediated by time to dropout. Dichotomous initial PM interacted with drug, suggesting a benefit of fluoxetine for low-PM smokers. Results indicate that lower pretreatment PM may inhibit long-term cessation. Smokers with lower baseline PM may benefit from treatment that increases PM. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do people aggress to improve their mood? Catharsis beliefs, affect regulation opportunity, and aggressive responding.

Do people aggress to make themselves feel better? We adapted a procedure used by G. K. Manucia, D. J. Baumann, and R. B. Cialdini (1984), in which some participants are given a bogus mood-freezing pill that makes affect regulation efforts ineffective. In Study 1, people who had been induced to believe in the value of catharsis and venting anger responded more aggressively than did control participants to insulting criticism, but this aggression was eliminated by the mood-freezing pill. Study 2 showed similar results among people with high anger-out (i.e., expressing and venting anger) tendencies. Studies 3 and 4 provided questionnaire data consistent with these interpretations, and Study 5 replicated the findings of Studies 1 and 2 using measures more directly concerned with affect regulation. Taken together, these results suggest that many people may engage in aggression to regulate (improve) their own affective states. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
