Effects of responses to depression on the remediation of depressive affect

The effects of different types of responses to a depressed mood on the duration and severity of the mood were examined. On the basis of Nolen-Hoeksema's (1987) response styles theory of depression, it was hypothesized that distracting, active responses would be more effective in alleviating a depressed mood than would ruminative, passive responses. A depressed mood was induced in 35 male and 34 female Ss, and subjects were randomly assigned to engage in 1 of 4 types of responses: an active task that distracted them from their mood; a passive, distracting task; an active task designed to lead to ruminations about their mood; or a passive, ruminative task. As predicted, the greatest remediation of depressed mood was found in Ss in the distracting-active response condition, followed in order by the distracting-passive, ruminative-active, and ruminative-passive response conditions. Degree of rumination had a greater impact on remediation of depressive affect than level of activity, with greater rumination leading to lesser remediation of depressive affect. In addition, the effects of the response tasks were limited to depressed mood. The implications of these results for interventions with depressed persons are discussed.

Mental state decoding in past major depression: Effect of sad versus happy mood induction

Individuals with mild depression show an enhanced ability to read or “decode” others' mental states. The goal of the present study was to investigate whether this pattern of performance is related specifically to the pathology of depression or whether it is simply a feature of the transient dysphoric state. Forty-one undergraduates with a previous episode of major depression and 52 undergraduates with no depression history participated in a mental state decoding task following a sad versus happy mood induction. Previously depressed participants were significantly more accurate in their mental state judgements than were the never-depressed participants, suggesting that enhanced mental state decoding may be a specific feature of depression in remission. Furthermore, previously depressed participants whose positive mood increased in response to the happy mood induction showed a poorer level of performance on the task, similar to that observed in the never-depressed group. Thus, a happy mood may have induced a somewhat less accurate, but perhaps more adaptive, approach to processing social information. These findings were robust after controlling for current level of depression and anxiety symptoms, intensity of response to the mood induction, response times, and performance on a control task.     

Gender differences in responses to depressed mood in a college sample

Two studies tested the hypothesis that women are more likely than men to focus on themselves and their mood when in a depressed mood, and that this leads them to experience longer periods of depressed mood. In both studies subjects were predominantly Caucasian college students. In our first study, a laboratory study, females chose to engage in an emotion-related task significantly more often than did males, even when this lead them to focus on an existing sad mood. In the second study, a prospective naturalistic study, females were more likely than males to evince an emotion-focused ruminative style of coping with their moods. A ruminative response style at Time 1 was a significant predictor of depression scores at Time 2, even after initial levels of depressed mood were taken into account. Furthermore, once rumination levels were controlled for, gender was no longer a potent predictor of depression outcome. The implications of these response styles for treatment are discussed.We thank Brandi Battistoni, Kim Bergquist, Rachel Carr, Lisa Lougee, and especially Ariel Lang for their invaluable help in data collection.

Switching and backward inhibition in major depressive disorder: the role of rumination

Previous studies have demonstrated that individuals with major depressive disorder have difficulties switching attention from one task set to another. In the current study we examined whether ruminative thinking drives the switching deficits of depressed individuals. A secondary, more exploratory, goal of this study was to examine whether state rumination would impair depressed individuals' ability to activate a new task set, to inhibit a no longer relevant task set, or both. Participants underwent either a rumination induction or a distraction induction and then completed a backward inhibition task that measures general switching abilities and the ability to inhibit previous task sets. Although depression was not related to switching ability as a main effect, depressed individuals who were induced to ruminate exhibited poorer switching ability than did both depressed and control individuals who were distracted from ruminating and control participants who were induced to ruminate. These findings suggest that depressed individuals are characterized by switching deficits only if they are ruminating. Moreover, the finding that state rumination did not affect participants' ability to inhibit previous task sets suggests that state rumination primarily impairs noninhibitory task-switching processes. It is interesting that the opposite pattern of results was obtained for trait rumination, which was related to inhibitory deficits during switching, but not to generally poorer switching. Thus, state and trait rumination may be associated with dissociable cognitive deficits.     

Construct accessibility and depression: an examination of cognitive and affective factors

Two studies in which the parameters of construct accessibility in depression were examined are reported. In Experiment 1, depressed and nondepressed subjects were required to name the colors of tachistiscopically presented depressed-content, neutral-content, and manic-content words. Because of the predicted accessibility and interference effects of the depressed-content words, the depressed subjects were expected to demonstrate longer response latencies to these words than to the non-depressed-content words. This response pattern was found for the depressed subjects; the nondepressed subjects did not demonstrate differential response latencies. In Experiment 2, a mood-induction paradigm was used to investigate whether the interference effects obtained in Experiment 1 were due to temporary mood differences between the depressed and nondepressed subjects, or were a function of more stable depression-associated patterns of information processing. Although predicted group differences were obtained on a mood adjective checklist, no effects were found for task performance. These results suggest that transient mood is not a sufficient explanation for the results obtained in Experiment 1. The implications of the present findings for the understanding of both construct accessibility and depression are discussed, and directions for future research are suggested.     

Experimental modification of attribution processes

Attributional style is hypothesized to be a causative factor in depression vulnerability; however, no studies to date have examined whether manipulation of attributional style influences depressed mood. The purpose of this study was to determine whether computer-based cognitive bias modification (CBM) procedures could modify attributional style and influence stress vulnerability. Participants were provided with multiple training trials that were intended to promote the use of either a positive or a negative attributional style. Compared with individuals in the negative attributional style condition, individuals in the positive attributional style condition showed decreased tendency to make self-deficient causal attributions for poor performance on a difficult anagram test. Furthermore, individuals in the positive attributional style condition reported less depressed mood in response to this academic stressor. These results suggest that attributional style is not invariable and can potentially be modified with CBM approaches.     

Cognitive aspects of chronic depression

Previous research on chronic depression has focused on its link with other mood disorders and Axis II personality disorders. However, there are few data examining whether the cognitive perspective applies to this condition. In this cross-sectional study, 42 outpatients with chronic depression were compared with 27 outpatients with nonchronic major depressive disorder and 24 never psychiatrically ill controls on cognitive variables thought to be related to vulnerability to depression (e.g., dysfunctional attitudes, attributional style, a ruminative response style, and maladaptive core beliefs). Both depressed groups were more elevated than a never-ill comparison group. However, chronically depressed individuals were generally more elevated on measures of cognitive variables than those with major depressive disorders even after controlling for mood state and personality disorder symptoms.     

Links Between Antisocial Behavior and Depressed Mood: The Role of Life Events and Attributional Style

Comorbidity between antisocial behavior and depression in adolescence is widely recognized. This paper examines whether links with depressed mood differ among three subtypes of antisocial behavior: oppositionality, physical aggression and delinquency. In addition we examine two possible contributors to these links: negative life events that are dependent upon the individual's actions and depressogenic attributional style. Data are drawn from the G1219 large-scale community twin and sibling sample, and include 2409 questionnaire responses from youths aged between 13 and 19 living in the United Kingdom. Depressed mood was independently associated with both oppositionality and delinquency, but not with physical aggression. Dependent negative life events were strongly implicated in the association between delinquency and depressed mood, whereas depressogenic attributional style was implicated in the associations of both oppositionality and delinquency with depressed mood. Oppositionality remained a significant predictor of depressed mood after accounting for attributional style and life events whereas delinquency did not. The pattern of associations was largely similar in boys and girls. We discuss these results in terms of developmental models of the links between antisocial behavior and depressed mood.     

Interactions between emotion regulation strategies and affective style: Implications for trait anxiety versus depressed mood

Affective style reflecting approach and inhibition is thought to be associated in distinct ways with anxious versus depressed mood; relatively few studies, however, consider how the interaction between affective style and the strategies individuals use to regulate mood and emotion might influence these associations. Sixty-seven non-disordered adults self-reported on their use of two emotion regulation strategies (cognitive reappraisal and expressive suppression), behavioral approach (BAS) and behavioral inhibition sensitivity (BIS) dimensions of affective style, and anxious and depressed mood (trait anxiety and symptoms of depression). Trait anxiety versus depressed mood was associated with unique interactive patterns of emotion regulation and affective style: enhanced use of reappraisal was linked to less depressed mood in those reporting low BAS, whereas high suppression was linked to greater trait anxiety in those reporting low BIS. The implications of findings for typical emotional processes and for clinical disorders and interventions are discussed.

Perceived parenting style, self-esteem and psychological distress in adolescents with heart disease

The aim of the study was to assess the relationships between perceived parenting style, depressed mood, anxiety and self-esteem in adolescents with heart disease compared with healthy adolescents. Forty-five adolescents, aged 12-18 with congenital or acquired heart disease and 50 healthy age-matched adolescents answered perceived parental behaviour, self-esteem, depressed mood and anxiety questionnaires. The study group reported higher perceived acceptance and lower perceived parental control than healthy adolescents, but similar levels of depressed mood, anxiety and self-esteem. Fischer's r-to-z transformation and regression analyses showed different associations between perceived parenting style and depressed mood, anxiety and self esteem. In the study group, higher perceived parental acceptance was associated with lower depressed mood and higher self-esteem, whereas these associations were not significant in the control group. In the control, but not the study group, higher perceived parental control was associated with lower depressed mood and lower anxiety. Parenting style proved to exert a differential effect on adolescents with and without heart disease. For the former, perceived parental acceptance had a more substantial effect on psychological well-being than perceived parental control. Professionals caring for these adolescents should be aware of the special importance of parenting style on the well-being of adolescents with heart disease, and address this issue in the clinical setting with the patients and their parents.     

Positive mood is associated with the implicit use of distraction

Previous research demonstrates that individuals in a positive mood are differentially distracted by irrelevant information during an ongoing task (Rowe et al. in Proc Natl Acad Sci 104:383–388, 2007). The present study investigated whether susceptibility to distraction shown by individuals in a positive mood results in greater implicit memory for that distraction. Participants performed a similarity-judgment task on pictures that were superimposed with distracting words. When these previously distracting words could be used as solutions on a delayed implicit task administered several minutes later, performance was positively correlated with pleasantness of mood. Individuals in a positive mood are more likely than others to use previously irrelevant information to facilitate performance on a subsequent implicit task, a finding with implications for the relationship between positive mood and creativity.     

Delighted and distracted: positive affect increases priming for irrelevant information

Emotional states are known to influence how people process relevant information. Here, we address the impact of emotional state on irrelevant information. In this experiment, participants were randomly assigned to a neutral or positive mood induction, and then completed a task that involved viewing a sequence of overlapping pictures and words. They were instructed to attend to the pictures and ignore the distracting words. Following a filled interval, implicit memory for the distracting words was tested using a word fragment completion task. Individuals in the positive mood group showed increased implicit memory for previously irrelevant information compared to those in the neutral mood group. These findings are consistent with the view that positive mood broadens attention to include encoding of irrelevant information in the environment, and this can impact subsequent performance.     

Attentional Biases for Emotional Faces in Young Children of Mothers with Chronic or Recurrent Depression

Attentional biases for negative stimuli have been observed in school-age and adolescent children of depressed mothers and may reflect a vulnerability to depression. The direction of these biases and whether they can be identified in early childhood remains unclear. The current study examined attentional biases in 5–7-year-old children of depressed and non-depressed mothers. Following a mood induction, children participated in a dot-probe task assessing biases for sad and happy faces. There was a significant interaction of group and sex: daughters of depressed mothers attended selectively to sad faces, while children of controls and sons of depressed mothers did not exhibit biases. No effects were found for happy stimuli. These findings suggest that attentional biases are discernible in early childhood and may be vulnerability markers for depression. The results also raise the possibility that sex differences in cognitive biases are evident before the emergence of sex differences in the prevalence of depression.     

Mood-induced changes on the Implicit Association Test in recovered depressed patients

A mood induction paradigm was used to examine dysphoria-related changes in two types of cognitive processing in individuals who had previously experienced depression. Formerly depressed patients (n = 23) and never-depressed controls (n = 27) completed the Dysfunctional Attitudes Scale, a self-report measure of effortful processing, and performed the Implicit Association Test, an automatic-reaction time task that measures evaluative bias, before and after a negative-mood induction. The formerly depressed group showed both an increase in endorsement of dysfunctional attitudes and a more negative evaluative bias for self-relevant information after the induction, relative to controls--however, there was no association between the mood-linked changes observed on these two measures. The shift in evaluative bias shown by the formerly depressed group was similar to that seen in a group of 32 currently depressed individuals. These findings suggest that even a mild negative mood in formerly depressed individuals can reinstate some of the cognitive features observed in depression itself.     

Vulnerability to depression: cognitive reactivity and parental bonding in high-risk individuals

Although various conceptual proposals have suggested that disruptions in childhood bonding processes may be linked to the origins of these cognitive structures, little research has tested these proposals. This study assessed the information processing of vulnerable individuals and its relationship to childhood bonding. Formerly depressed (vulnerable) and never depressed (nonvulnerable) individuals participated in a mood induction task followed by an attentional allocation task. Results indicated that vulnerable individuals uniquely diverted attention toward negative stimuli when they were in a negative mood. Furthermore, level of maternal caring was found to be associated with performance on this task for vulnerable individuals in this mood state. These data support the idea that cognitive variables form a pathway between troublesome parental-child/adolescent interactions and depression.     

Affective and cognitive characteristics of depression in 10- and 11-year-old children

Indices of emotion experiences, attribution style, and intellectual performance were regressed on an index of childhood depression. The results indicated that the depressed children were like depressed adults in that they reported experiencing a pattern of emotions including sadness, anger, self-directed hostility, and shame, and they tended to explain negative events in terms of internal, stable, and global causes. The similarity between depressed children and depressed adults on these measures was greater for girls than for boys. Depression was not related to performance on a verbal task, but depressed girls performed worse than nondepressed girls on a block design task. The measures of emotion experiences accounted for 78.1% and 46.1% of the variance in girls' and boys' depression scores, respectively, after the variance accounted for by attribution style was partialed out.
