Psychological strain and suicidal ideation in young university students during Covid-19 outbreak: the mediating roles of rumination and depression.

The link between psychological strain and suicidal ideation is well embedded in literature, however, the underlying mechanism is rarely explored. Therefore, this study aimed to examine the relationship between psychological strain, suicidal ideation, rumination, and depression among Pakistani young adults during the Covid-19 outbreak. In addition, it will also try to determine the mediating role of ruminative subtypes and depression in the relationship between psychological strain and suicidal ideation. The sample consists of 400 university students (83 males and 289 females) with the age range from 18 to 30 years (M = 22.25, SD = 2.40). Psychological strain scale, Suicidal Ideation Scale, Beck Depression Inventory, and Ruminative Response Scale were administered to the participants. Results indicated a significant and positive association between the study variables. Psychological strain positively influenced suicidal ideation both directly, and indirectly via brooding and depression. Both variables were found to be serially mediated by the brooding subtype of rumination and depression and not with the reflective subtype. Strain theory of suicide and response style theory also postulated important insights regarding the association of these variables in young adults, among which, strain is serially related to first brooding and then depression, which is eventually related to suicidal ideation. The present study makes a significant contribution to the literature by providing a unique conceptual and theoretical framework to identify suicide at the ideation level before it proceeds to behavior during this unprecedented time of the pandemic outbreak.

Executive Functioning and Negative Affect: an Examination of the Meditational Effects of Emotion Regulation

Recent data highlight maladaptive emotion regulation strategies as a transdiagnostic risk factor. Executive functioning (EF) is also conceptualized as a transdiagnostic mechanism. Drawing these two areas together, data supports the intervening role of rumination, a form of emotion regulation, in the EF clinical symptomatology link. However, research has yet to fully examine various emotion regulation strategies as transdiagnostic mechanisms in youth. The relationship between EF components, emotion regulation strategies, and transdiagnostic negative affect was examined. Set-shifting was associated with general emotion regulation difficulties as well as rumination, worry, and thought suppression. Inhibition was only related to general emotion regulation difficulties and the brooding subtype of rumination. Finally, various forms of emotion regulation were observed to mediate the relationship between set-shifting and negative affect.

Early life stress predicts negative urgency through brooding, depending on 5-HTTLPR genotype: A pilot study with 6-month follow-up examining suicide ideation

The present study examined the interaction between early life stress and 5-HTT genotypes in predicting two risk factors for suicidal behavior – the brooding subtype of rumination and impulsivity, in the form of negative urgency – over time. Furthermore, we examined early life stress, brooding, and impulsivity as predictors of suicidal ideation over time. Participants with and without a history of early life stress were genotyped for the 5-HTTLPR polymorphism and completed assessments assessing brooding and negative urgency at baseline and 6-month follow up. Early life emotional abuse was associated with negative urgency at follow-up. We found an indirect effect of early life emotional abuse on negative urgency through brooding among individuals with 5-HTT low expressing genotypes but not among individuals with 5-HTT high expressing genotypes. Further, a logistic regression analysis revealed that negative urgency was associated with higher odds (O.R. = 16.2) of reporting suicide ideation (versus no ideation) at follow-up. Our findings suggest that brooding and negative urgency may result from the interaction between early life emotional abuse and 5-HTT low expressing genotypes. Further research is necessary to understand how early life stress interacts with 5-HTT genotypes to confer risk for suicidal behavior through psychological mechanisms.

Positive future-oriented fantasies and depressive symptoms: Indirect relationship through brooding.

Although a positive future outlook is generally associated with psychological well-being, indulging in positive fantasies about the future has been found to exacerbate negative mood-related outcomes such as depressive symptoms. We examined rumination as a cognitive mechanism in this relationship, using an objectively coded measure of future-oriented fantasies, among 261 young adults assessed twice. Engaging in a positive fantasy about the future was associated with the brooding subtype of rumination but not with reflection at baseline. There was an indirect relationship between fantasies at baseline and depressive symptoms at six-week follow-up through brooding at average and high levels of fantasy positivity when fantasizing was consistent or increased over time but not when it decreased. Engaging in fantasies was indirectly associated with perceived difficulty anticipating likely positive future outcomes through brooding. These findings extend previous research on positive fantasies by suggesting brooding as a mechanism to explain when they are maladaptive.

Stress-Related Symptoms and Suicidal Ideation: The Roles of Rumination and Depressive Symptoms Vary by Gender.

There is a growing body of literature suggesting that reactions to stressful life events, such as intrusive thoughts, physiological hyperarousal, and cognitive/behavioral avoidance (i.e., stress-related symptoms) may increase risk for thinking about and attempting suicide. Cognitive vulnerability models have identified rumination (i.e., perseverating on a negative mood) as a maladaptive response that may increase risk for suicidal behavior, as it has also been linked to depression. The present study examined the direct and indirect effects of stress-related symptoms on suicidal ideation through rumination and depressive symptoms. Participants were 1375 young adults, primarily non-White (78 %) females (72 %), recruited from a public university in the Northeastern U.S., who completed measures of stress-related symptoms (as a response to a stressful event), rumination, depressive symptoms, and suicidal ideation. The relation between stress-related symptoms and suicidal ideation was accounted for by the brooding subtype of rumination and depressive symptoms among females. Depressive symptoms, but not rumination, better accounted for suicidal ideation among males. These findings suggest that the role of brooding and depressive symptoms in the relationship between stress-related symptoms and suicidal ideation may vary by gender.

P.3.034 Brooding subtype of rumination is modulated by the interplay between serotonin receptor 2A gene and childhood adversity

In recent years, sophisticated fate-mapping tools have been developed to study the behavior of stem cells in the intact organism. These experimental approaches are beginning to yield a quantitative picture of how cell numbers are regulated during steady state and in response to challenges. Focusing on hematopoiesis and immune responses, we discuss how novel mathematical approaches driven by these fate-mapping data have provided insights into the dynamics and topology of cellular differentiation pathways in vivo. The combination of experiment and theory has allowed to quantify the degree of self-renewal in stem and progenitor cells, shown how native hematopoiesis differs fundamentally from post-transplantation hematopoiesis, and uncovered that the diversification of T lymphocytes during immune responses resembles tissue renewal driven by stem cells.

Examining the Relation Between Mood and Rumination in Remitted Depressed Individuals

Cognitive theories of recurrent depression suggest that the relationship between mood and cognition is altered by previous depressive episodes. In individuals remitted from depression (RMD) this would be linked to a larger susceptibility for new depressive symptoms. This study explored whether the association between mood and rumination indeed is different between RMD and nondepressed controls relying on dynamic systems theory (DST). From DST we selected entropy, defined here as the level of unpredictability in the relation between mood and rumination, as the main variable of interest. Daily electronic dairy measures of mood and rumination were administered in 31 RMD patients and 32 healthy controls. The results indicate that mean levels of rumination and negative mood were elevated in RMD compared with controls. At the group level, entropy did not differ significantly and entropy was also not associated with the number of episodes. However, entropy predicted depressive symptoms in the RMD group and the brooding subtype of rumination in both groups at the 6-month follow-up. These data are specific for entropy and were not obtained using mean levels of momentary mood and rumination.

The internalizing pathway to adolescent substance use disorders: Mediation by ruminative reflection and ruminative brooding

Two subtypes of rumination were examined in relationship to substance use and substance use disorders in adolescents. In the 8th and 9th grade, 521 adolescents completed measures assessing depressive symptoms, conduct problems, and reflective and brooding subtypes of rumination. In 12th grade, adolescents reported substance use and were administered the substance use disorders modules from the DISC. Path analyses conducted with data from 428 participants indicated that neither depression nor rumination variables significantly affected the presence of substance use. However, indirect effects of depression through reflection and brooding were differentially related to risk of developing substance use disorders, with brooding positively associated with Marijuana Use Disorders, and reflection negatively related to both Marijuana and Alcohol Use Disorders. Pathways did not differ by sex. These findings suggest that promoting self-reflection may be an effective strategy to prevent and intervene with the development of problematic substance use.

Cognitive Vulnerability to Emotional Symptoms: Reconsidering the Role of Worry and Rumination

The present study explored the pathways whereby cognitive variables (worry, rumination) may explain the relation between neuroticism and emotional symptoms in a community sample of adults (N = 499). All participants completed a battery of questionnaires including measures of neuroticism, worry, rumination, anxiety and depression. Multiple mediation and moderated mediation analyses were used. Worry was a common pathway explaining the effect of neuroticism on both anxiety and depressive symptoms. The brooding subtype of rumination significantly mediated the relation between neuroticism and anxiety symptoms, but the reflection subtype did not have a mediating effect. Although worry by itself mediated the association between neuroticism and anxiety symptoms, it required a certain level of brooding to exert its mediating effect on the relation between neuroticism and depressive symptoms. The results are discussed in light of previous research and recent developments in treatment. Clinical implications and suggestions for future research are also discussed.

Brooding and reflective rumination among suicide attempters: Cognitive vulnerability to suicidal ideation

Previous research suggests that the brooding subtype of rumination is associated with increased suicidal ideation, but findings are inconsistent with respect to reflection, considered to be the more adaptive form of rumination. This study investigated the circumstances under which reflective rumination might be associated with increased suicidal ideation by examining whether a suicide attempt history moderated the relationship between the ruminative subtypes and current suicidal ideation. Thirty-seven young adults who reported a past suicide attempt and fifty-nine young adults without a suicide attempt history completed measures of rumination and depression symptoms in an initial study session. They then completed a measure of suicidal ideation and hopelessness during a second study session. Overall, brooding was associated with higher self-reported suicidal ideation, whereas reflection was not significantly associated with ideation. However, reflection – but not brooding – interacted with suicide attempt history to statistically predict suicidal ideation, even after adjusting for symptoms of depression and hopelessness, whereas brooding no longer predicted ideation after adjusting for these symptoms. These findings qualify earlier suggestions that reflection is a more adaptive form of rumination by indicating that among vulnerable individuals – in particular those with a history of a suicide attempt – a higher degree of reflective rumination is associated with increased suicidal ideation.
