Frequency and duration of mood fluctuations: effects of dependency, self-criticism, and negative events

Few studies have examined the relation between depressive vulnerability factors and the duration of symptom disturbance, defined as the length of time during which mood states are elevated above a certain threshold. We examined the duration of mood disturbances in male (N=31) and female (N=71) college-aged individuals who completed mood checklists twice weekly for 10 weeks. Results showed that dependency and self-criticism were related to the mean severity of ratings across all checklists and the mean duration of disturbances, as well as the number of disturbances lasting at least 7 or 14 days. Some evidence for the congruency model was found. Dependency and self-criticism moderated the relation between vulnerability congruent hassles and mood. Sensitivity analyses showed that altering the threshold at which symptom scores were designated as symptom disturbances did not affect the pattern of results for dependency and self-criticism. Results have implications for the debate concerning the relation between vulnerability factors and depressive severity.     

Effects of alcohol,rumination, and gender on the time course of negative affect

This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants (N?=?263) completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.     

Organizing Interactions in the Study of Judgmental Accuracy

Over the last two decades, an emphasis on cognitive factors in depression has contributed significantly to the psychological modeling of this disorder and to the development of effective treatments. This work has spanned basic processes of mood and cognition regulation as well as more applied work in the evaluation of psychotherapy outcome, short-term therapy delivery, and adherence to protocol. Reconciliation of cognitive models of depression with more recent experimental work, and the implications of the success of models that emphasize primarily noncognitive variables in predicting and treating depression, has yet to be fully explored. To grapple with these challenges, the Consensus Development Conference on Cognitive Models of Depression was convened to appraise the field and advise on future directions in the areas of cognitive models, cognitive assessment, cognitive vulnerability, and theoretical integration. This report describes obstacles to the continued progress of this approach for understanding affective disorders and psychological distress in general and offers specific recommendations for research strategies thought to be most productive for their resolution.     

5-HTTLPR,HTR1A,and HTR2A cumulative genetic score interacts with mood reactivity to predict mood-congruent gaze bias

Genetic variation within the serotonin system has been associated with biased attention for affective stimuli and, less consistently, with vulnerability for major depressive disorder. In particular, 5-HTTLPR, HTR1A (rs6295), and HTR2A (rs6311) polymorphisms have been linked with biased cognition. The present study developed a serotonergic cumulative genetic score (CGS) that quantified the number of risk alleles associated with these candidate polymorphisms to yield a single CGS. The CGS was then used to model genetic influence on the relationship between reactivity to a negative mood induction and negatively biased cognition. A passive-viewing eye-tracking task was administered to 170 healthy volunteers to assess sustained attention for positive, dysphoric, neutral, and threatening scenes. Participants were then induced into a sad mood and readministered the passive-viewing task. Change in gaze bias, as a function of reactivity to mood induction, was the primary measure of cognitive vulnerability. Results suggest that, although none of the individual genes interacted with mood reactivity to predict change in gaze bias, individuals with higher serotonin CGS were significantly more likely to look toward dysphoric images and away from positive images as mood reactivity increased. These findings suggest that a CGS approach may better capture genetic influences on cognitive vulnerability and reaffirm the need to examine multilocus approaches in genomic research.     

Personality and mood correlates of avoidant personality disorder

Avoidant personality disorder (APD) has been recognized as prevalent and clinically important; however, it is not clear how APD maps onto established personality and mood dimensions. In this cross-sectional survey study, 365 college students completed questionnaires assessing APD features and theoretically relevant personality and mood dimensions. Based on these self-report data, 6.6% may meet DSM-IV criteria for APD. Hierarchical regression analyses showed that APD features were associated with introversion, neuroticism, low self-esteem, and pessimistic expectancies. Additionally, APD features were linked with self-reports of elevated emotional responsiveness to threats and reduced emotional responsiveness to incentives (the behavioral inhibition system and behavioral activation system scales). After controlling for the effects of other personality, temperament, and cognitive measures, affective distress (i.e., anger, anxiety, and depression) was no longer related to APD. Results are consistent with APD models that emphasize the joint influences of emotional vulnerability and social-cognitive triggering and sustaining factors.     

The Mediating Role of Automatic Thoughts in the Personality–Event–Affect Relationship

Although cognitive theory gives automatic thoughts a causal role in the onset of negative mood and depressive symptoms, little research has directly tested this relationship, and no research has examined whether automatic thoughts explain the effects of personality factors, life events, and positive mood on negative affect. Accordingly, automatic thoughts were prospectively tested as a mediator of the effects of personality vulnerability factors, positive affect, and hassles on mood. Measures of self-criticism and dependency were administered at baseline, and measures of automatic thoughts, hassles, and positive and negative affect were administered once per week for 4 weeks to 102 college students. Automatic thoughts fully mediated the effects of self-criticism and partially mediated the effects of dependency and hassles on mood. Findings suggest that negative thoughts only partially account for the relationship among personality, hassles, and mood. Results also showed that the impact of positive affect on negative affect may be mediated by the presence or absence of automatic thoughts.     

The subjective–agentic personality sector (SAPS): Introduction to the special issue on self,identity, and psychopathology

This special issue is predicated upon the premise that there exists a subjective–agentic personality sector (SAPS) that is crucially relevant to the understanding and treatment of psychopathology. SAPS is often overlooked by “trait” models in personality psychology. It is comprised of “hot” cognitions about one's self and identity as they unfold throughout the life span and are brought to bear on interpersonal relationships. There are four ways in which SAPS may be involved in psychopathology: (a) inherently, as a component of psychiatric disorders, (b) as a passive vulnerability dimension, namely by interacting with life stress, (c) as an active vulnerability dimension, that is, by propelling external situations that culminate in psychopathology, and (d) by constituting a central consequent of psychopathology (i.e., the scarring pattern, see below). In this Journal of Personality special issue, experts in personality and psychopathology demonstrate the centrality of SAPS in unipolar depression, anxiety disorders, bipolar spectrum disorder, eating disorders, posttraumatic stress disorder, complex trauma and borderline personality disorder, social anxiety disorder, suicidality in the context of mood disorders, and recovery from schizophrenia. A commentary by Dan McAdams, a leader in the study of self and identity, concludes this special issue.     

Creative Cognition and Psychosis Vulnerability: What’s the Difference?

Evidence from experimental psychology provides unequivocal support for enhanced creativity among individuals who are prone to psychotic and mood disorders. At the same time, there is strong epidemiological evidence for greater incidence of creative achievement among those diagnosed with bipolar disorder (but not schizophrenia). This review examines the evidence for common factors predisposing an individual to creativity and psychosis, as well as factors that distinguish the capacity for creative achievement from the creative potential that may be inherent in psychosis vulnerability. Factors implicated as common to creative potential and psychosis vulnerability include enhanced divergent thinking, reduced latent inhibition and preattentive filtering mechanisms; on the other hand, greater cognitive flexibility, motivation, and openness to experience tend to be associated with creative achievement, but not psychosis. This evidence is considered with respect to the utility of tailored vocational interventions to effectively harness creative potential, which may be useful for young individuals in the early stages of illness or their unaffected family members.     

Biased processing of emotional information in girls at risk for depression

Researchers have documented that children of depressed mothers are at elevated risk for developing a depressive disorder themselves. There is currently little understanding, however, of what factors place these children at elevated risk. In the present study, the authors investigated whether never-disordered daughters whose mothers have experienced recurrent episodes of depression during their daughters' lifetime are characterized by biased processing of emotional information. Following a negative mood induction, participants completed an emotional-faces dot-probe task. Daughters at elevated risk for depression, but not control daughters of never-disordered mothers, selectively attended to negative facial expressions. In contrast, only control daughters selectively attended to positive facial expressions. These results provide support for cognitive vulnerability models of depression.     

Understanding vulnerability for depression from a cognitive neuroscience perspective: A reappraisal of attentional factors and a new conceptual framework

We propose a framework to understand increases in vulnerability for depression after recurrent episodes that links attention processes and schema activation to negative mood states, by integrating cognitive and neurobiological findings. Depression is characterized by a mood-congruent attentional bias at later stages of information processing. The basic idea of our framework is that decreased activity in prefrontal areas, mediated by the serotonin metabolism which the HPA axis controls, is associated with an impaired attenuation of subcortical regions, resulting in prolonged activation of the amygdala in response to stressors in the environment. Reduced prefrontal control in interaction with depressogenic schemas leads to impaired ability to exert attentional inhibitory control over negative elaborative processes such as rumination, leading in turn to sustained negative affect. These elaborative processes are triggered by the activation of negative schemas after confrontation with stressors. In our framework, attentional impairments are postulated as a crucial process in explaining the increasing vulnerability after depressive episodes, linking cognitive and biological vulnerability factors. We review the empirical data on the biological factors associated with the attentional impairments and detail how they are associated with rumination and mood regulation. The aim of our framework is to stimulate translational research.     

Predictors of Health Self-Appraisal: What's Involved in Feeling Healthy?

Increased interest in the prevention of illness underscores the importance of understanding how people evaluate their health. This study investigated self-report measures of health status, medical complaints, and psychosocial factors in 455 undergraduates. After controlling for neuroticism, regression analyses indicated that positive mood, negative mood, perceived vulnerability to illness, and vitality were significant contributors to self-assessed health independent of physical symptoms and diseases. Together, psychosocial factors accounted for more variance in health assessments (R² = .44) than did disease and symptom reports alone (R² = .25; p. < .01 for all betas). These results demonstrate the strong association of psychosocial stares with evaluations of health and suggest that physical discomfort may play a relatively minor role in how "healthy" we feel.     

Cognitive processes in hoarding: The role of rumination

Rumination, defined as an individual's repetitive negative cognitions of upsetting symptoms in response to distress, has been established as an important cognitive vulnerability factor within various forms of psychopathology. Despite compelling data to suggest that rumination is associated with a number of mood and anxiety-related conditions, no research to date has examined the relationship between rumination and hoarding. Participants consisted of 275 undergraduate students as well as 106 individuals recruited from the community to participate in a larger randomized clinical trial investigating the effects of a computerized treatment targeting specific risk factors associated with anxiety and suicide. Consistent with initial prediction, results indicated that rumination was a significant predictor of hoarding severity, even after controlling for overall general levels of depression. These findings add to a growing body of literature identifying various cognitive vulnerability factors important for the development and maintenance of hoarding. Increasing our knowledge of cognitive vulnerability factors has import implications for the prevention and treatment of anxiety disorders.     

Eyewitness memory: The impact of a negative mood during encoding and/or retrieval upon recall of a non-emotive event

The police often appeal for eyewitnesses to events that were unlikely to have been emotive when observed. An eyewitness, however, may be in a negative mood whilst encoding or retrieving such events as mood can be influenced by a range of personal, social, and environmental factors. For example, bad weather can induce a negative mood. This experiment compared the impact of negative and neutral moods during encoding and/or retrieval upon eyewitness recall of a non-emotive event. A negative mood during encoding had no impact upon the number of correct details recalled (provided participants were in a neutral mood at retrieval) but a negative mood during retrieval impaired the number of correct details recalled (provided participants were in a neutral mood at encoding). A negative mood at both time points enhanced the number of correct details recalled, demonstrating a mood-dependent memory enhancement. The forensic implications of these findings are discussed.     

Unique association of approach motivation and mania vulnerability

Bipolar disorder involves experiences of both mania and depression over time, and measures of mania-risk and depression-risk therefore tend to be correlated, making it difficult to disentangle the shared versus unique aspects of mania and depression vulnerability. In theory, strong approach motivation is uniquely linked with mania risk, but this relation tends to be obscured unless co-occurring depression risk is statistically controlled. In this study, 461 college students completed the General Behaviour Inventory (GBI)—a validated questionnaire of bipolar disorder vulnerability—and they reported their degree of approach motivation in response to four vignettes that varied in relative incentive versus threat strength. After controlling for the effect of depression vulnerability, mania vulnerability was associated with approach motivation, particularly in response to more threatening scenarios, and this association remained significant even when controlling for dispositional threat and incentive responsiveness, current symptoms, mood, self-esteem, and optimism. The results are consistent with models that regard heightened approach motivation as a unique aspect of mania vulnerability.     

The association of perimenopausal mood disorders with other reproductive-related disorders

Data regarding the increased incidence of psychiatric illness during midlife in women are still conflicting. However, there is a growing consensus that certain groups of women may in fact be at higher risk for mood symptoms and psychiatric disorders during the perimenopausal transition. Mood symptoms during the perimenopause may be related to mood disorders during other periods of hormonal fluctuation throughout a woman's reproductive lifecycle. Elucidating these associations may advance the understanding of mood disorders during the perimenopausal transition. The epidemiology and treatment of perimenopausal mood symptoms compared with the epidemiology and treatment of mood disorders during the late luteal phase of the menstrual cycle, pregnancy, and postpartum. Common risk factors associated with mood disorders during these periods of hormonal changes or instability include poor lifestyle habits, a history of hormonally related mood disorders, stress and negative life events, ethnicity, and comorbidity. Reproductive-related mood disorders also are subject to an improvement in symptoms in response to treatment with selective serotonin reuptake inhibitors. As the morbidity associated with mood disorders during midlife may be quite significant, and as life expectancy continues to increase, recognition, prevention, and treatment of perimenopausal affective illness is becoming increasingly essential.     

Endorsement of dysfunctional beliefs depends on current mood state

In two studies we tested the hypothesis that endorsement of dysfunctional beliefs depends on current mood state for persons who are vulnerable to depression. The first study showed that reports of dysfunctional beliefs vary with spontaneous diurnal mood fluctuations in 47 depressed psychiatric patients. The effect of mood state was highly significant (p less than .01); dysfunctional thinking increased when mood was worst and decreased when mood was best. The second study conceptually replicated this finding in a population of asymptomatic subjects. As predicted, reports of dysfunctional beliefs varied as a function of mood state in 14 persons who had experienced a depressive episode but not in 27 who had never been depressed. These findings support the cognitive theory of depression, which proposes that dysfunctional beliefs are vulnerability factors for depression but also that reporting of dysfunctional beliefs depends on current mood state.     

Depressive symptoms and cognitive control in a mixed antisaccade task: specific effects of depressive rumination

Growing empirical evidence suggests that cognitive and affective problems in depression may be a reflection of cognitive control impairments. However, to date, the nature of such impairments is still poorly understood and further investigation of this topic is required to advance current knowledge on the underlying vulnerability factors for depression. Using a mixed antisaccade paradigm, the present study examined if depressive symptoms in general, and more specifically rumination, are related to impairments in cognitive control functions such as inhibition and switching. The results on antisaccade latency and error rates indicated that depressive symptoms in general were not related to impairments in inhibition and switching. However, rumination was associated with impaired inhibition such that high, compared to low, ruminators had slower antisaccade latencies. No group differences were observed on antisaccade error rates. Implications for understanding the underlying vulnerability factors for the development of depressive symptoms are discussed.     

Drivers’ and cyclists’ safety perceptions in overtaking maneuvers

Drivers overtaking cyclists on rural roads are a safety concern, as drivers need to handle the interaction with the cyclist and possibly an oncoming vehicle. Improving the maneuver’s outcome requires an understanding of not only the objective, measurable safety metrics, but also the subjective, perceived safety of each road user. Previous research has shown that the perceived safety of the cyclist is most at risk at the passing moment, when driver and cyclist are closest to each other. However, to develop safety measures, it is necessary to know how both road users perceive safety, by understanding the factors that influence their perceptions during the overtaking maneuver. This study measured the perceived safety of drivers in a test-track experiment in Sweden and the perceived safety of cyclists in a field test in Spain. For both drivers and cyclists, we developed Bayesian ordinal logistic regression models of perceived safety scores that take as input objective safety metrics representing the different crash risks at the passing moment. Our results show that while drivers’ perceived safety decreases when there is an oncoming vehicle with a low time-to-collision, cyclists’ perceived safety is reduced by a small lateral clearance and a high overtaking speed. Although our datasets are heterogeneous and limited, our results are in line with previous research. In addition, the Bayesian models presented in this paper are novel and may be improved in future studies once more naturalistic data become available. We discuss how our models may support infrastructure development and regulation, policymaking, driver coaching, the development of active safety systems, and automated driving by providing a possible method for predicting perceived safety.
