The mediating effect of rumination and fear of missing out between mobile phone addiction and sleep quality among college students

The impact of mobile phone addiction (MPA) on college students’ sleep quality (SQ) has received increasing attention in recent years. On this basis, the mediating roles of rumination and FOMO (fear of missing out) on MPA and SQ were examined in this study. In a cross-sectional study, preliminary data were gathered via questionnaires from 1401 college students (19.35 ± 0.81) from 5 universities in Jiangxi Province, China. Mobile Phone Addiction Tendency Scale, Rumination Response Scale, Fear of Missing Out Scale and Sleep Quality Scale were employed in the research. The mediation model was tested using SPSS 26.0, with FOMO and rumination acting as the mediating variables. Between MPA and SQ, rumination and FOMO each had their own unique mediation effect. Furthermore, rumination and FOMO function as a chain of mediators between college students’ MPA and SQ. This study provided confirmation and clarification that in college students, the association between MPA and SQ was mediated by rumination and FOMO. This study improves our understanding of MPA, SQ and how MPA may affect SQ in college students. It also shows that the impact of MPA and SQ of college students should be given more consideration by educators, parents, and college students themselves.

Facilitating Thought Progression to Reduce Depressive Symptoms: Randomized Controlled Trial.

The constant rise in the prevalence of major depressive disorder calls for new, effective, and accessible interventions that can rapidly and effectively reach a wide range of audiences. Recent developments in the digital health domain suggest that dedicated online platforms may potentially address this gap. Focusing on targeting ruminative thought, a major symptomatic hallmark of depression, in this study we hypothesized that delivering a digital health-based intervention designed to systematically facilitate thought progression would substantially alleviate depression. The study aims to investigate the efficacy of a novel digital intervention on the reduction of depressive symptoms. This intervention was designed as an easy-to-use gamified app specifically aimed to facilitate thought progression through intense practicing of associative, semantically broad, fast, and creative thought patterns. A randomized clinical trial was conducted, comparing changes in depression symptoms between participants who used the app in the intervention group (n=74) and waitlist control group (n=27) over the course of 8 weeks. All participants filled out a battery of clinical questionnaires to assess the severity of depression at baseline and 4 and 8 weeks after starting the study. These primarily included the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Patient Health Questionnaire-9 as well as the Positive Affect Negative Affect Scale-Negative Affect Score, Ruminative Response Scale, and Symptoms of Depression Questionnaire. Additional questionnaires were implemented to assess anxiety, positive affect, anhedonia, and quality of life. The results indicate that across multiple clinical measurements, participants in the intervention group who played the gamified app showed greater and faster improvement in depressive symptoms compared with their waitlist control counterparts. The difference between the groups in MADRS improvement was -7.01 points (95% CI -10.72 to -3.29; P<.001; Cohen d=0.67). Furthermore, the difference in improvement between groups persisted up to 4 weeks posttrial (MADRS differences at week 12: F49,2=6.62; P=.003; ηp2=0.21). At the end of the trial, participants who played the app showed high interest in continuing using the app. The results demonstrate that a gamified app designed to facilitate thought progression is associated with improvement in depressive symptoms. Given its innovative and accessibility features, this gamified method aiming to facilitate thought progression may successfully complement traditional treatments for depression in the future, providing a safe and impactful way to enhance the lives of individuals experiencing depression and anxiety.

Examining the indirect effects of acculturation stress on insomnia through rumination and alcohol use among Latinx women and men.

Acculturation stress, a type of sociocultural stress, is positively associated with insomnia among Latinxs; however, the mechanisms of this association remain elusive. We tested the indirect effects of acculturation stress on insomnia through rumination and alcohol use, two coping strategies associated with insomnia, and explored these effects in gender-stratified models among Latinxs. We analyzed cross-sectional data from 187 Latinxs participating in the Latino Sleep and Health study in New York City in 2016-2019. We conducted bias-corrected boot-strap tests of mediation with case resampling (1,000 replications) in aggregate and gender-stratified models. Acculturation stress and insomnia were measured continuously using the Hispanic Stress Inventory and Insomnia Severity Index (ISI). Rumination was measured using a subscale of the Ruminative Response Scale. The Quantity-Frequency Index was used to measure alcohol use. Covariates included age, New York City poverty threshold, and perceived stress. Participants were Mage 37.43 (SD = 13.67). Most participants were women (64.17%). The average ISI was 6.65 (SD = 5.51). The indirect effect of acculturation stress on insomnia through rumination was statistically significant (b = 0.02, 95% BCa CI [0.01, 0.03]). Among women, this indirect effect had slightly larger coefficients than among men (b = 0.02, 95% BCa CI [0.01, 0.04]; b = 0.01, 95% BCa CI [0.004, 0.04]). Alcohol use was not a statistically significant mediator (b = -0.001, 95% BCa CI [-0.004, 0.0002]). These findings suggest that psychological interventions focused on reducing rumination in response to acculturation stress may promote healthy sleep among Latinxs, particularly among Latina women. Future studies should use longitudinal study designs to determine the causal relationships among these variables. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The temporal dynamics of perceived stress and depression in college students: An ecological momentary assessment.

Previous studies have implied that stress is a risk factor for depression, but relatively little is known about how healthy individuals' stress dynamically affects depression as a mood in daily life. Therefore, an ecological momentary assessment study was conducted among 141 college students to test the temporal dynamic effect of daily perceived stress on depression and the underlying mediating and moderating role of rumination. Perceived stress, state rumination, and depression were measured using self-compiled questionnaire three times a day over 12 days. Trait rumination was measured with the Nolen-Hoeksema Ruminative Response Scale. Hierarchical linear models with HLM 7.0 were adopted to examine the mediation and moderation effects. In the mediation model, the greater the daily perceived stress at time t, the higher the state rumination at time t + 1, and state rumination at t + 1 positively predicted college students' depression at t + 2. In the moderation model, trait rumination significantly facilitated perceived stress-induced depression. These results verified that daily perceived stress could affect college students' depression directly or indirectly through the critical mediating mechanism of state rumination, and this effect would be exacerbated with a higher level of trait rumination.

Structural alterations in a rumination-related network in patients with major depressive disorder

Rumination is a common symptom in major depressive disorder (MDD). Previous work has connected individual differences in rumination to structural properties in various brain regions. Some of these, such as the dorsolateral prefrontal cortex (dlPFC), have also been highlighted as being altered in MDD, suggesting a connection between structural changes and ruminative symptoms. Although informative, such localised relations have limitations in the context of a network view of the brain. To further investigate rumination-related structural changes in depression, and to situate these within potential functional networks, we acquired T1-weighted structural MRI data from patients with MDD (n=32) and controls (n=69). Rumination was measured with the Rumination Response Scale. Surface-based, whole-brain analysis of cortical grey-matter identified group differences in the dlPFC that were, however, not related to rumination. Instead, rumination was correlated with grey-matter properties in the right precuneus. Using normative functional connectivity analysis on an independent sample (n = 100), we show these two regions to be interconnected. Further developing a network-based perspective, it was shown that the rumination-related precuneus region is connected with networks associated with processes such as executive function, autobiographical memory, and visual perception. Notably, these processes have been connected to rumination. These results suggest that rumination in depression may be linked to focal structural changes. The effects of these focal changes on rumination may then be connected to their influence on distributed functional networks.

The association between aspects of expressive suppression emotion regulation strategy and rumination traits: a network analysis approach

Expressive suppression is an abnormal emotion regulation strategy, and its relationship with rumination traits is unclear. In this study with 395 participants in China (33.9% female, Mean age = 21.22, SD = 2.11), we estimated the association between expressive suppression and rumination traits, using the Rumination Response Scale (RRS) and the Emotion Regulation Questionnaire (ERQ) respectively. Considering there may be complex correlations between different behavioral symptoms of expressive suppression (“Keeping emotions to myself”, “Inhibiting positive emotion responses”, “Controlling emotions by not expressing them”, “Inhibiting negative emotion responses”) and different subtypes of rumination traits, this study employed a symptom-based network analysis method to uncover the differential association between rumination traits and expressive suppression, and the key symptoms linking the two. The study found the S3 node (Controlling emotions by not expressing them) had significant positive correlations with symptom rumination, brooding, and reflective pondering. Among the network, the S3 node acts as a bridge between two variables. This suggests that interventions targeting the S3 symptom may improve rumination traits. The present study was a cross-sectional study with limitations in revealing the causal relationships between expression suppression and rumination traits. Future studies could employ longitudinal tracing methods to explore the relationship between them.

Affective temperament, attachment style and life events related to abandonment in an Italian sample with somatic symptoms

ObjectiveThis study investigates the psychological factors influencing somatic symptoms following the end of a romantic relationship. We hypothesize that affective temperaments may predict attachment styles and depressive rumination components in individuals who have experienced abandonment. Furthermore, we postulate that gender differences exist in the variables under investigation. MethodsThe administered tests included: Temperament Evaluation of Memphis, Pisa, Paris and San Diego Questionnaire (TEMPS-A), Attachment Style Questionnaire (ASQ) and Ruminative Response Scale (RRS). The differences between the groups were assessed using Student's t-test for independent samples. In addition, regression analysis, in which the RRS (Brooding, Reflection and Depression) and ASQ (Confidence, Discomfort with Closeness, Need for Approval, Preoccupation with Relationships, and Relationships as Secondary) variables were considered dependent variables and all the TEMPS-A factors were included in the equation. ResultsSubjects at the end of a love affair presented the following psychosomatic symptoms: difficulty breathing, chest pain, feeling faint, sweating, dizziness, fatigue, palpitations, air hunger, difficulty sleeping, and swollen legs and ankles. The Anxious and Hyperthymic temperaments were negative predictors of the ruminative depressive dimension, and of “Confidence” and “Discomfort with Closeness” in the ASQ. The Cyclothymic and Anxious temperaments were predictors of “Discomfort with Closeness”, “Need for Approval”, “Preoccupation with Relationships”, and “Relationships as Secondary”. ConclusionAffective temperaments play a crucial role in determining how an individual deals abandonment in a romantic relationship, significantly influencing attachment styles and the tendency towards depressive rumination.

The burden of brooding on neural error processing: The role of repetitive negative thinking in major depressive disorder with and without comorbid anxiety disorders

BackgroundRepetitive negative thinking (RNT), particularly its brooding aspect, is a prominent feature in Major Depressive Disorder (MDD) with and without comorbid anxiety. Error processing, an adaptive cognitive operation, seems to be impaired in individuals with exaggerated RNT. This study measured a post-error neural response, error-related negativity (ERN), during an inhibitory task to examine the mechanism underlying the relationship between RNT and faulty error processing. MethodsWe examined current MDD patients with (n = 61) and without comorbid anxiety disorders (COM; n = 38), propensity-matched into High- or Low-RNT groups according to Ruminative Response Scale Brooding subscale scores. Using 32-channel electroencephalography (EEG) during a stop-signal task, we measured baseline-corrected ERN amplitude at FCz 0–100 ms after an incorrect response. A between-subjects ANOVA was conducted with group (High RNT, Low RNT) and comorbidity (MDD, COM) as factors. ResultsA significant group-by-comorbidity interaction (η2 = 0.07) was found, with MDD participants exhibiting high RNT revealing smaller (more positive) ERN amplitudes compared to their COM counterparts with high RNT (d = 0.77) and MDD participants with low RNT (d = 0.92). ConclusionsNon-anxious individuals with MDD and high RNT showed blunted post-error neural responses, potentially indicating a diminished adaptive neural mechanism for recognizing and correcting errors. However, the presence of comorbid anxiety disorders in individuals with high RNT appears to counteract this reduction, potentially through an enhanced neural response to errors, thereby maintaining a higher level of error-processing activity. Further understanding of these relationships is essential for developing targeted interventions for MDD, with particular focus on the detrimental impact of brooding RNT.

Effectiveness of Self-compassion Therapy for Distress Tolerance and Rumination in Women with Multiple Sclerosis

Background: Multiple sclerosis (MS) patients face many challenges that significantly affect their daily lives. Multiple sclerosis symptoms are unpredictable and can disrupt work, relationships, and social interactions, leading to emotional consequences like anxiety and depression, as well as social stigma. Objectives: This study aimed to evaluate the effectiveness of self-compassion therapy for distress tolerance and rumination in women with MS. Methods: This quasi-experimental study adopted a pretest-posttest design with a control group and recruited women aged 18 - 55 diagnosed with MS by a neurologist who visited the MS Society of Ahvaz, Iran, in 2023. Forty participants diagnosed with MS were randomly assigned to two groups (control group: n = 20; experimental group: n = 20). The experimental group received self-compassion therapy delivered in eight 90-minute sessions. The control group did not receive the intervention and instead served as a waitlist control. The research instruments included the Distress Tolerance Scale (DTS) and Ruminative Response Scale (RRS). The data were analyzed using analysis of covariance in SPSS V.27. Results: Posttest results revealed significant between-group differences. The experimental group exhibited lower mean scores (mean ± SD = 46.13 ± 3.40 for distress tolerance, 35.41 ± 3.41 for rumination) compared to the control group (mean ± SD = 27.71 ± 4.27 for distress tolerance, 53.90 ± 5.83 for rumination). The results demonstrated that self-compassion therapy significantly diminished rumination and enhanced distress tolerance in the experimental group. Conclusions: This study demonstrated that self-compassion therapy has the potential to be an effective intervention for reducing rumination and enhancing distress tolerance in women with MS. However, further research with more extensive and diverse samples is necessary before recommending widespread adoption within healthcare settings.

Gender and trait rumination moderates the link between trait impulsivity and gambling problems severity in young adults

AimsTrait impulsivity and trait rumination appear to uniquely contribute to problem gambling. However, only a limited number of studies have investigated their relationship with each other, and no study has tested whether their interplay could explain problem gambling. In this study, we aimed to examine these associations, especially focusing on the putative moderator role of gender. MethodsThe present study utilized data from the first wave of the Budapest Longitudinal Study, representatively surveying young adults. The final, weighted sample consisted of N = 1202 (649 men; mean age = 28.04 years; SD = 4.31) participants who reported gambling in the past year. Gambling severity was assessed by the Problem Gambling Severity Index (PGSI), trait impulsivity was measured by Barratt Impulsiveness Scale short form (BIS-R-10), while rumination was assessed by the short version of Ruminative Response Scale (RRS). ResultsMultiple linear regression analysis showed significant positive association between impulsivity and problematic gambling, and we found that both trait rumination and gender moderated this association, even after controlling for depressed mood, age, level of education, and subjective relative wealth. For men, when the level of trait rumination was high, higher levels of trait impulsivity were associated with an increase in gambling problems. However, these associations were not found among women. ConclusionsOur results suggested that the interplay of trait rumination and trait impulsivity might contribute to problem gambling, potentially by the impulsive desire to alleviate negative mood states. Our results also revealed that these associations could be stronger among men than in women.

Effects of Transcranial Direct-Current Stimulation on Rumination and Self-inhibition in Patients with Panic Disorder

Background: Panic disorder causes patients to cease their daily activities and avoid social interactions. Appropriate treatment helps these patients manage their worries, rumination, and self-inhibition, allowing them to return to normalcy. Objectives: This research aims to investigate the effectiveness of transcranial direct-current stimulation (tDCS) on rumination and self-inhibition in patients with panic disorder. Methods: This quasi-experimental research used a pretest-posttest control group design. The statistical population comprised patients with panic disorder aged 18 - 45 years who visited psychotherapy centers in Ahvaz, Iran, in 2023. Convenience sampling was employed to select 40 eligible participants, who were then randomly assigned to an experimental group (n = 20) and a control group (n = 20). Participants completed rumination and self-inhibition questionnaires at the pretest and posttest stages. The experimental group received ten 20-minute sessions of tDCS. Data were collected using the Ruminative Response Scale (RRS) and Self-Restraint Scale (SRS). Analysis of covariance (ANCOVA) was used for data analysis. Results: The results indicated that tDCS improved rumination and self-inhibition in the posttest stage, demonstrating the treatment's effectiveness (P &lt; 0.001). Conclusions: Transcranial direct-current stimulation can alleviate rumination and improve self-inhibition in patients with panic disorder. It is recommended that tDCS be used as a complementary treatment for these patients.

THE RELATIONSHIP BETWEEN PSYCHOLOGICAL PAIN, RUMINATION AND SUICIDE AND ACNE SEVERITY IN ACNE VULGARIS PATIENTS

Objective: Acne vulgaris is among dermatological diseases that increase suicide risk significantly. We aimed to investigate the relationship between suicide risk and acne severity, psychological pain, and especially brooding rumination in 18-36 year old acne vulgaris patients. Material and Methods: Our study was conducted with 103 acne vulgaris patients and 87 healthy controls. Study data were collected with a Socio-demographic Data Form, Global Acne Scoring System (GASS), Suicide Probability Scale (SPS), Psychological Pain Scale (PPS), Rumination Response Scale – Short Form (RRS-SF), and Beck Depression Inventory (BDI). Results: It was determined that median brooding rumination, total SPS scores and Hopelesness, hostility subscale scores were statistically significantly higher in the patient group (p values; 0.035, 0.006, 0.032, 0.007). In the patient group, the analysis of the correlations between the GASS and scale scores when the BDI score is controlled demonstrated that there were weak positive correlations between SPS despair and hostility subscale scores and total SPS score and PPS and brooding rumination scores (p: 0.003; r: 0.270), (p:0.014; r: 0.218), (p:0.010; r:0.229),(p:&amp;lt;0.001; r:0.389), (p:0.001, r: 0.304), (p:0.010; r:0.229). It was determined that brooding rumination, PPS and GASS scores contributed significantly to the multiple linear regression model structured estimate of the total SPS score. Conclusion: Since the suicidal risk of acne patients with acne who present to dermatology clinics could be high, it is important to follow up these patients with the psychiatry clinic, and in addition to acne treatment, therapeutic interventions that aim to reduce ruminative ideation and psychological pain could significantly contribute to the reduction of suicide risk.

The chain mediating role of rumination and social withdrawal in the relationship between smartphone distraction and depression among Chinese nursing students

Smartphone distraction (SD) is closely related to depression, and the prevalence of SD among nursing students is gradually increasing. However, the potential mechanism of the effect of SD on nursing students’ depression is unclear. A total of 574 nursing students were assessed using Smartphone Distraction Scale, Ruminative Response Scale, Hikikomori Questionnaire, and Patient Health Questionnaire-9. The results indicated that SD among nursing students had an impact on depression through four pathways: (1) SD was positively associated with depression (β = 0.353, P < 0.001); (2) Rumination (β = 0.199, 95% CI: 0.081 to 0.162) and social withdrawal (β = 0.061, 95% CI: 0.034 to 0.091) mediated the effects of SD on depression, respectively; and (3) Rumination and social withdrawal played a chain mediating role in the effect of SD on nursing students’ depression (β = 0.027, 95% CI: 0.015 to 0.042). The negative impact of SD on nursing students’ mental health should not be taken lightly. Schools and hospitals should guide nursing students to use smartphones correctly, including providing mental health education and professional psychological counselling; families could play a supervisory role and communicate regularly to understand the psychological state and learning of nursing students. These measures can help nursing students cope with stress and reduce the risk of depression.

Childhood Trauma and Non-Suicidal Self-Injury Among Chinese Adolescents: The Chain-Mediated Role of Alexithymia and Rumination.

To explore the associations between childhood trauma, alexithymia, rumination, and non-suicidal self-injury (NSSI) among adolescents and to provide theoretical and empirical evidence for effective prevention, identification, and intervention of NSSI in the future. Questionnaires, including the Childhood Trauma Questionnaire, the twenty-item Toronto Alexithymia scale, the Ruminative Responses Scale, and the Adolescents Self-Harm Scale, were given to 1,270 Chinese teenagers. The mediating role was simulated utilizing Amos 24.0. The Pearson's product-difference correlation analyses indicated the two-by-two significant correlations between childhood trauma, alexithymia, rumination, and NSSI. The structural equation modeling suggests that alexithymia and rumination partially mediate between childhood trauma and NSSI in teenagers, respectively. Additionally, it reveals that alexithymia and rumination chain mediate between childhood trauma and NSSI. The study confirms the impact of childhood trauma on adolescents' NSSI and also highlights the mediating role of alexithymia and rumination between the two. This study enriches the findings of NSSI and provides a theoretical basis for preventing and intervening in dysfunctional behaviors among adolescents.

Golden steps: A nursing approach for vitality, agility, and rumination in geriatric clients with depressive disorders through mindful walking

BackgroundDepression is a prevalent issue among older adults and can significantly impact their overall quality of life. While traditional treatments may not always be sufficient or suitable for all individuals, the potential of alternative interventions, such as mindful walking, offers a ray of hope. This study aimed to evaluate the impact of mindful walking on rumination, agility, vitality, and mindfulness in geriatric patients with depressive disorders. MethodA prospective quasi-experimental design was employed with a purposive sample of 35 clients in the intervention group and 33 in the control group. This study utilized the Ruminative Responses Scale – Short Form (RRS-SF) and Five Facet Mindfulness Questionnaire (FFMQ) to measure the primary outcome. The Timed Up and Go Test (TUG) and State-Level Version of the Subjective Vitality Scale (SVS) were used to measure the secondary outcomes. ResultsMindful walking significantly affected vitality, mindfulness, and rumination, with effect sizes (ղ2 = 0.168, 0.137, and 0.127), respectively. On the other hand, the intervention had a less significant effect on agility, with an effect size (ղ2 = 0.047). ConclusionThis study revealed that geriatric clients with depressive disorders showed more significant improvements in vitality, followed by improvement in rumination and agility. Integrating mindful walking as a part of care plans for those clients would promote their physical activity and mental well-being.

Does rumination moderate the effect of attention bias modification for depressive symptoms?

BackgroundCurrent treatment of major depressive disorders still leave many patients with modest improvement. Attention Bias Modification (ABM) is an approach that may serve as an adjuvant therapy for subgroups of patients. We examined whether rumination, often found to be associated with a negative attentional bias, acts as a moderating variable in a computerized ABM procedure in participants with recurrent depression. MethodsA total of 301 patients were randomized to receive either active - or sham ABM twice daily for 14 days. A regression-based moderator analysis was applied to evaluate whether baseline brooding, from the Rumination Response Scale (RRS-B), moderated the effect of ABM on Hamilton Depression Rating Scale (HDRS) and Beck Depression Inventory II (BDI-II). ResultsThere was no significant interaction effect of ABM and RRS-B on HDRS or BDI-II at post-intervention or at 1 month follow-up. In addition, no correlation was found for pre-training attention bias and RRS-B. Limitations: Generalizability is limited to individuals with non-clinical symptom scores. ConclusionsThere was no moderator effect of brooding rumination on clinical depression scales in the largest clinical study on ABM to date.

The Relationship of Rumination, Worry and OCD Symptoms During Technology Supported Mindfulness Therapy for OCD.

In this study, we re-examined data from a previous randomized controlled trial investigating 'technology supported mindfulness' (TSM)-an 8-week treatment intervention for individuals experiencing OCD. The current analysis involves an examination of the longitudinal relationships between rumination, worry and OCD symptom changes during mindfulness treatment, in comparison to a waitlist control. Participants experiencing OCD (n = 71) were randomly assigned to 8 weeks of (1) TSM or (2) waitlist control. We tested the extent to which rumination (using the Ruminative Response Scale) and worry (using the Penn State Worry Questionnaire) are associated with OCD symptom changes during the acute phase of treatment, concurrently (i.e., within the same longitudinal model). Generalized linear model (GLM) results indicated a significant time (week 1 vs. week 8) by condition interaction involving decreased rumination in the TSM condition: F(1, 61) = 13.37, p = 0.001, partial η2 = 0.18 and observed power = 0.94. A second GLM demonstrated decreased worry in the TSM condition: F(1, 69) = 37.34, p = 0.001, partial η2 = 0.35 and observed power = 0.83. Longitudinal 'latent difference' structural equation analyses demonstrated a cross-lagged association between worry (but not rumination) and OCD symptom changes. Individuals in the TSM condition experienced greater reductions in rumination and worry during 8 weeks of TSM treatment compared to the waitlist control, and reduced worry predicted subsequent OCD symptom reduction.

Association between non-restorative sleep and psychotic-like experiences among Chinese college students: A latent profile and moderated mediation analysis

BackgroundNon-restorative sleep (NRS) is a core symptom of insomnia that has considerable consequences for daily life. However, the association between NRS and psychotic-like experiences (PLEs) remains unclear. The current study was designed to explore the relationship between NRS and PLEs as well as the mediation/moderation role of rumination and resilience among college students in China. Methods3060 college students were recruited from two universities in South China from September 21st to October 26th, 2022. Non-restorative Sleep Scale, 8-item Positive Subscale of the Community Assessment of Psychic Experiences, Ruminative Response Scale, and 10-item Connor-Davidson Resilience Scale were administered. Latent profile analysis and moderated mediation analysis were performed. Results11.3 % participants reported frequent PLEs in the past one month. Three profiles of rumination were identified and named as “low rumination” group (27.7 %), “medium rumination” group (55.3 %), and “high rumination” group (16.9 %). NRS directly predicted PLEs, and rumination played a significant mediation role between NRS and PLEs. Resilience significantly moderated the association between NRS and rumination as well as the association between NRS and PLEs. ConclusionsNRS, rumination and resilience are important predictors to PLEs. Strategies on increasing restorative sleep, decreasing rumination, and enhancing resilience are of great significance in the prevention of PLEs.

On assessing trait rumination using the Ruminative Response Scale.

This study explores the stability of scores on psychometrically validated trait questionnaires over time. We illustrate potential pitfalls through a larger study that used the Ruminative Response Scale (RRS) to categorize participants prior to study inclusion into two groups based on their habitual tendency to ruminate. Surprisingly, when we re-administered the RRS at the start of an experimental session, significant score changes occurred, resulting in participants shifting between the two groups. To address this, we modified our recruitment process, aiming to reduce careless responses, including an online RRS assessment a week before the lab appointment. We analyzed the different samples prior to and after changing the recruitment procedure, as well as the total sample regarding the psychometric properties of the RRS. We also explored various indices to identify and predict score changes due to careless responding; however, only a subgroup of participants was successfully identified. Our findings suggest that Mahalanobis distances are effective for identifying substantial score changes, with baseline state rumination emerging as a marginally significant predictor. We discuss the importance of conducting manipulation checks and offer practical implications for research involving psychometrically validated trait questionnaires.

Rumination in patients with major depressive disorder before and after antidepressant treatment

BackgroundRumination is a maladaptive response to distress characteristic of Major Depressive Disorder (MDD). It is unclear to what degree rumination is associated with depression severity prior to treatment and how it responds to antidepressant treatment. Therefore, we evaluated the association between rumination and depression severity in 92 untreated patients with MDD and explored the changes in rumination after initiation of antidepressant medication. MethodWe measured rumination using the Rumination Response Scale (RRS) and depression severity with the Hamilton Depression Rating Scale (HDRS17 or HDRS6) before and after initiation of 12 weeks of antidepressant treatment. The association between RRS and pre-treatment HDRS17 was evaluated using a linear regression model. RRS at week 4, 8, and 12 across treatment response categories (remission vs. non-response) were evaluated using a mixed effect model. ResultsRRS was positively associated with depression severity prior to treatment at a trend level (p = 0.06). After initiation of treatment RRS decreased significantly (p < 0.0001) and remitters exhibited lower rumination compared to non-responders at week 4 (p = 0.03), 8 (p = 0.01), and 12 (p = 0.007). LimitationsThe study had no placebo group. ConclusionsAlthough pre-treatment rumination did not significantly associate with depressive symptoms, rumination was closely connected to change in depressive symptoms. Tormented patients could be reassured that rumination symptoms may be alleviated over the course of antidepressant treatment.
