The Interplay between Rumination and Intrusions in the Prediction of Concurrent and Prospective Depressive Symptoms in Two Nonclinical Samples

Are the knowledge of non-malignant asbestos-related diseases and lung function impairment differentially associated with psychological well-being? A cross-sectional study in formerly asbestos-exposed workers in Germany

OBJECTIVES

The knowledge of past asbestos exposure may lead to chronic psychological strain. In addition, the information about an increased cancer risk can place a psychological burden on individuals triggering mental health symptoms of depression or anxiety. This applies in particular to individuals with non-malignant asbestos-related disease (ARD) such as lung fibrosis and pleural thickening with or without lung function impairment. ARDs with or without lung function impairment may develop even years after exposure cessation. Therefore, the aim of the present study was to test for our cohort whether non-malignant ARD and lung function impairment have differential effects on mental health and psychological strain.

DESIGN

Cross-sectional study.

PARTICIPANTS AND SETTING

Overall, 612 male participants (mean age=66.2 years, SD=9.5) attending a surveillance programme for ARDs received routine examinations including lung function testing (24% refused to fill in the psychological questionnaire) at a German university hospital study centre from August 2008 to August 2013.

OUTCOME MEASURES

Using multiple hierarchical regression analysis, ARD diagnosis and lung function impairment were used to predict psychological health as measured with validated questionnaires for depression and anxiety. Psychological strain was operationalised by intrusive thoughts and specific fear of cancer.

RESULTS

The strongest predictor for mental health was obstructive functional impairment (eg, anxiety: β=0.22, p<0.001). Psychological strain was predicted by the presence of a non-malignant ARD (eg, intrusive thoughts: β=0.17, p=0.003).

CONCLUSIONS

The presence of mental health symptoms is associated with ventilation disturbances, whereas the knowledge of an already initiated morphological change-caused by asbestos exposure-is primarily associated with psychological strain. Specifically, the affected individuals are more prone to intrusive thoughts and specific fear of asbestos-related cancer. As an implication, physicians should be sensitised about possible consequences of risk communication and functional impairment to counteract excessive fear or anxiety.

The tendency for experiencing involuntary future and past mental time travel is robustly related to thought suppression: an exploratory study

Involuntary mental time travel (MTT) refers to projecting oneself into the past or into the future without prior conscious effort. The previous studies have shown high inter-individual variability in the frequency of involuntary MTT, but a few systematic studies exist. In three exploratory studies, we investigated the relation between individual differences in experiencing involuntary past and future MTT, and selected emotional and cognitive processes, with a special focus on thought suppression. Across all three studies, thought suppression emerged as a robust predictor of involuntary MTT above and beyond emotion-related variables, mind-wandering, daydreaming styles, and demographic variables. Findings from Studies 1 and 2 showed that higher thought suppression consistently predicted both more frequent involuntary past and future MTT across an American and a Danish sample, whereas rumination and emotion regulation were less consistently related to involuntary MTT. In Study 3, thought suppression reliably predicted more frequent involuntary MTT, even when controlling for mind-wandering, as well as for positive and negative daydreaming styles, which were all related to greater involuntary MTT. Overall, the individual differences assessed showed similar relationships to the tendency for having past and future involuntary MTT, with the possible exception of daydreaming styles, which appeared more strongly related to future-directed involuntary MTT.

Association between intrusive negative autobiographical memories and depression: A meta-analytic investigation

The study investigated several associations between depression and intrusive negative autobiographical memories. A systematic literature search identified 23 eligible studies (N = 2,582), which provided 59 effect sizes. Separate meta-analyses indicated that depression was moderately, positively associated with intrusive memory frequency, memory distress, maladaptive memory appraisals, memory avoidance, and memory rumination. Intrusive memory vividness was not significantly associated with depression. There were insufficient data to examine the relationship between depression and memory vantage perspective. Between-study heterogeneity was high for intrusive memory frequency and memory avoidance, and the percentage of females in studies significantly moderated the relationship between these variables and depression. An additional exploratory meta-analysis (3 studies; N = 257) indicated that intrusive memories were experienced more frequently by those with posttraumatic stress disorder than those with depression. Overall, the findings suggest that intrusive memories warrant clinical attention as they may contribute to the maintenance of depressive symptomatology.

On the Integration of Need–related Autobiographical Memories among Late Adolescents and Late Adults: The Role of Depressive Symptoms and Self–congruence

Within self–determination theory, integration denotes the process through which people accept past and present experiences and harmonize these experiences within their sense of self. We investigated associations between indicators of successful and poor integration of need–related memories and memory–related affect. We also examined the role of depressive symptoms and self–congruence as antecedents of these indicators. Moreover, we investigated whether late adults, compared with late adolescents, were better capable of integrating need–frustrating memories through higher levels of self–congruence. Participants were 132 late adolescents (Mage = 17.83) and 147 late adults (Mage = 76.13), who reported on their level of depressive symptoms and self–congruence. Next, participants generated a need–satisfying and need–frustrating memory and reported on the memories‘ integration (in terms of acceptance, connection and rumination) and associated affect. Whereas depressive symptoms related mainly to the poor integration of need–frustrating memories, self–congruence related positively to the integration of both need–satisfying and need–frustrating memories. In turn, integration was related to more positive and less negative affect. Late adults scored higher than late adolescents on the integration of need–frustrating memories, an effect that was partly accounted for by late adults‘ elevated self–congruence. Results suggest that self–congruence, depressive symptoms and age play a role in the integration of need–based autobiographical memories.

Understanding Dysregulated Behaviors and Compulsions: An Extension of the Emotional Cascade Model and the Mediating Role of Intrusive Thoughts

Objective: The Emotional Cascade Model (ECM) by Selby et al. (2008) proposes that people often engage in dysregulated behaviors to end extreme, aversive emotional states triggered by a self-perpetuating vicious cycle of (excessive) rumination, negative affect, and attempts to suppress negative thoughts.

Method: Besides replicating the ECM, we introduced intrusions as a mediator between rumination and behavioral dysregulation and tested this extended ECM for compulsions as part of obsessive–compulsive disorders. A structural equation modeling approach was used to test this in a sample of N = 414, randomly recruited from the general population.

Results: Intrusions were found to fully mediate the effect of rumination on a broad array of dysregulated behaviors and compulsions. This mediation endured when controlling for symptoms of depression.

Conclusion: These findings support the idea that rumination fuels intrusions, which in turn foster dysregulated behaviors. Therefore, addressing rumination as well as intrusions may improve psychotherapeutic interventions for mental disorders characterized by dysregulated behaviors and/or extreme aversive emotional states.

Balancing emotional processing with ongoing cognitive activity: the effects of task modality on intrusions and rumination

In the present paper we aimed to show that competition for resources between post-emotional processes and the execution of a cognitive task will result in two possible effects: (1) an impairment of the cognitive task in the short run and (2) an elongation of intrusions and rumination in the long run. The outcome of this competition is influenced by the interaction of the modality (verbal vs. visuospatial) of cognitive tasks run in the aftermath of an emotional experience and the nature (verbal vs. visuospatial) of the same experience. Non-clinical participants were given a working memory task (OSPAN vs. an analog Visual task) before and after the presentation of negative vs. neutral material (a novel excerpt in Experiment 1 and a video clip in Experiment 2). Intrusions and rumination were measured after a 24-h delay. Rumination was also assessed immediately after the experimental induction. Results showed that exposure to verbal negative material impaired verbal performance (Experiment 1); by contrast, exposure to visual negative material impaired both verbal and visuospatial performance (Experiment 2). Intrusions were only affected by the emotional valence of the original experience, while performing a visuospatial task resulted in enhanced rumination only after exposure to verbal emotional material. The findings of both experiments suggest that emotional processing spreads over time in balance with ongoing cognitive activities, and, in such a balance, the visuospatial processing mode tends to prevail over verbal engagements.

Anticipatory and Post-Event Rumination in Social Anxiety Disorder: A Review of the Theoretical and Empirical Literature

Social anxiety disorder (SAD) is a psychological disorder characterised by an excessive and persistent fear of social or performance situations, which interferes with daily functioning. Cognitive models of SAD (Clark & Wells, 1995; Hofmann, 2007; Rapee & Heimberg, 1997) emphasise the importance of negative pre- and post-event rumination as a maintaining factor in the cycle of SAD. While the link between negative rumination and SAD is well supported by empirical research, little is understood about this cognitively important process; thus, research investigating the predictors of negative rumination in SAD is important to consider. Within the current literature, performance appraisal appears to be the most likely unique cognitive predictor of post-event rumination. There is limited research into cognitive predictors of pre-event rumination. Treatments targeting this maintaining factor are important to consider. Suggestions for future research examining the cognitive models of SAD by experimentally manipulating perceived social standards in order to examine the impact of high and low perceived social standard on appraisal processes (i.e., threat appraisal and performance appraisal), state social anxiety, and negative pre-event and post-event rumination, are proposed. Implications for theoretical models and efficacious treatments for SAD are discussed.
