Repetitive Negative Thinking Predicts Depressed Mood at 3-Year Follow-up in Students

Repetitive negative thinking (RNT; e.g., rumination and worry) is a key-factor involved in the maintenance of emotional problems like depression and anxiety. Recently, the Perseverative Thinking Questionnaire (PTQ) was developed as a content-independent measure of RNT. The current study investigated the validity of this new measure in predicting depressive symptoms prospectively. Eighty-one students completed measures of depressive symptoms, depressive rumination and repetitive negative thinking. Depressive symptoms were re-assessed 3?years later (40?months follow-up). Results showed that repetitive negative thinking as measured by the PTQ predicts depressive symptoms at follow-up, even when taking into account baseline depressive symptoms and rumination. The results suggest that the PTQ has good (prospective) predictive validity for depressed mood and reconfirm RNT’s role in the course of emotional complaints.     

When Being Discrepant from One's Ideal or Ought Selves Hurts: The Moderating Role of Neuroticism

Self‐discrepancy theory posits that people experience emotional consequences when they perceive discrepancies between their actual and possible selves. However, the extent to which people react emotionally to these self‐discrepancies (i.e. ideal, ought and undesired) may be a function of individual differences in neuroticism. Across both experimental (Study 1; N = 155) and correlational designs (Study 2; N = 139) involving college students, the authors demonstrated that neuroticism moderated the discrepancy–emotion associations such that high‐neuroticism individuals showed elevated depression and anxiety symptoms when their self‐discrepancies were activated. The heightened symptoms were maintained over time. Negative repetitive thoughts (i.e. rumination and worry) were examined as potential mediating mechanisms between the discrepancy × neuroticism interaction and symptoms. Partial support was obtained in that rumination mediated between undesired discrepancy × neuroticism interaction and anxious/depressive symptoms. Implications and possible theoretical extensions for self‐discrepancy theory are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Repetitive Thought and Self-Reported Sleep Disturbance

Repetitive thought has been focused upon as a transdiagnostic risk factor for depression, anxiety, and poor physical health. Among the forms of repetitive thought, rumination and worry are considered to play important roles in the onset and maintenance of insomnia. However, there have been few attempts to clarify the similarities, differences, and interaction between the functions of rumination and worry in sleep problems. Furthermore, no study has investigated the prospective relationships between these two forms of repetitive thought and sleep disturbance. In the present study, we examined the prospective associations between repetitive thought and subjective sleep quality, measured by a self-report questionnaire. A total of 208 undergraduates participated in a 2-wave longitudinal survey with an interval of 3 weeks between assessments. Hierarchical multiple regression analyses showed that baseline rumination predicted reduction in the follow-up assessment of subjective sleep quality, controlling for levels of depressive and anxious symptoms. This main effect of rumination was qualified by the levels of worry; for individuals with higher levels of worry, rumination was associated with greater reduction in subjective sleep quality. These results suggest that both rumination and worry have unique associations with sleep and that their interaction is especially important in sleep problems.     

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.     

Neuroticism,Life Events and Negative Thoughts in the Development of Depression in Adolescent Girls

Theories of depression suggest that cognitive and environmental factors may explain the relationship between personality and depression. This study tested such a model in early adolescence, incorporating neuroticism, stress-generation and negative automatic thoughts in the development of depressive symptoms. Participants (896 girls, mean age 12.3 years) completed measures of personality and depressive symptoms, and 12 months later completed measures of depressive symptoms, recent stressors and negative automatic thoughts. Path analysis supported a model in which neuroticism serves as a distal vulnerability for depression, conferring a risk of experiencing dependent negative events and negative automatic thoughts, which fully mediate the effect of neuroticism on later depression. A second path supported a maintenance model for depression in adolescence, with initial levels of depression predicting dependent negative events, negative automatic thoughts and subsequent depressive symptoms. Unexpectedly, initial depression was also associated with later independent life events. This study establishes potential mechanisms through which personality contributes to the development of depression in adolescent girls.     

Intelligence and emotional disorders: Is the worrying and ruminating mind a more intelligent mind?

Previous research has shown that anxiety and depression symptoms are negatively associated with measures of intelligence. However, this research has often not taken state distress and test anxiety into account, and recent findings indicate possible positive relationships between generalized anxiety disorder (GAD), worry, and intelligence. The present study examined the relationships between GAD, depression, and social anxiety symptoms, as well as their underlying cognitive processes of worry, rumination, and post-event processing, with verbal and non-verbal intelligence in an undergraduate sample (N = 126). While the results indicate that verbal intelligence has positive relationships with GAD and depression symptoms when test anxiety and state negative affect were taken into account, these relationships became non-significant when overlapping variance was controlled for. However, verbal intelligence was a unique positive predictor of worry and rumination severity. Non-verbal intelligence was a unique negative predictor of post-event processing. The possible connections between intelligence and the cognitive processes that underlie emotional disorders are discussed.     

Anxiety,Depression, and Procrastination Among Students: Rumination Plays a Larger Mediating Role than Worry

Procrastination is prevalent among students and is associated with negative outcomes, including poor academic performance and psychological distress. Research also suggests that anxiety and depression can exacerbate procrastination; however, the mechanisms associated with the development of procrastination are less understood. The current study aimed to clarify the role of negative repetitive thought (i.e., rumination and worry) in the links between anxiety and procrastination, and depression and procrastination. Ninety-one undergraduate students completed self-report measures of anxiety, depression, worry, brooding rumination, and procrastination, and two multiple mediator models were tested. Procrastination was positively correlated with the study variables, including medium effects for anxiety and depression, a large effect for rumination, and a small effect for worry. Rumination independently mediated the relationships between anxiety and procrastination, and depression and procrastination. Worry did not independently mediate these relationships. The current findings suggest rumination plays a larger role in the links between anxiety, depression, and procrastination than worry. Thus, students with higher levels of anxiety and depression engage in more negative repetitive thought, which may contribute to procrastinatory behavior as a result of a preoccupation with depressing or painful thoughts about the past.     

Rumination and worrying as possible mediators in the relation between neuroticism and symptoms of depression and anxiety in clinically depressed individuals

Rumination and worrying are considered possible mediating variables that may explain the relation between neuroticism and symptoms of depression and anxiety. The current study sought to examine the mediational effects of rumination and worry in the relationships between neuroticism and symptoms of depression and anxiety in a sample of clinically depressed individuals (N = 198). All patients completed a battery of questionnaires including measures of neuroticism, rumination, worrying, depression, and anxiety. Results showed that in subsequent analyses, rumination and worrying both mediated the relation between neuroticism and depression and anxiety. When rumination and worrying were simultaneously entered in the mediation analysis, only rumination was found to mediate the relation between neuroticism and symptoms of anxiety and depression. Two components of rumination (i.e., brooding and reflection) were also analyzed in the mediational analysis. Both reflection and brooding were significant mediators with respect to depressive symptoms, whereas brooding was the only significant mediator in relation to anxiety symptoms. The results are discussed in the light of current theories, previous research, and recent treatment developments. Clinical implications and suggestions for future research are provided.     

Does worry affect adjustment to bereavement? A longitudinal investigation

Background and objectives: Repetitive thought is a trans-diagnostic risk-factor for development of psychopathology. Research on repetitive thought in bereaved individuals has focused primarily on clarifying the role of rumination, repetitive thinking about past negative events and/or negative emotions. While detrimental effects of rumination have been demonstrated following bereavement, surprisingly few studies have aimed to clarify the role of worry, repetitive thinking about potential future negative events, in adjustment to loss. This study sought to fill this gap in knowledge. Methods/Design: One hundred eighty-three bereaved individuals (85.3% women) filled out questionnaires on sociodemographic and loss-related characteristics, worry, and symptom measures of depression, anxiety, and prolonged grief. After six months, 155 participants completed worry and symptom measures again. Using multiple regression analyses, concurrent and longitudinal associations between loss-related variables, worry, and symptoms of psychopathology were examined. Results: Main results were that worry was strongly positively associated with symptoms of anxiety, depression and prolonged grief concurrently and also predicted higher levels of anxiety, depression and prolonged grief longitudinally. Conclusions: Findings suggest that worry influences adjustment to bereavement negatively and may be a potential target in grief therapy, especially when aiming to reduce anxiety.     

Repetitive Thought and Health Anxiety: Tests of Specificity

Researchers suggest that worry, rumination, and unwanted intrusive thoughts are forms of repetitive thought (RT) important to health anxiety. To better understand RT-health anxiety interrelations, four tests of specificity between these three forms of RT and health anxiety were completed in the present research using a large community sample of medically healthy adults (N = 410). Results were that worry and rumination shared particularly strong zero-order correlations with health anxiety. In addition, worry, rumination, and unwanted intrusive thoughts each shared statistically stronger zero-order correlations with health anxiety than did another form of RT (i.e., reflection). Moreover, worry, rumination, and unwanted intrusive thoughts each shared unique relations with health anxiety after accounting for negative affect. Finally, these three forms of RT each evidenced incremental validity beyond one another as they relate to health anxiety. The pattern of relations was replicated across three commonly used measures of health anxiety. Implications for the conceptualization, assessment, and treatment of health anxiety are discussed.     

Psychometric Qualities of Turkish Version of Perseverative Thinking Questionnaire (PTQ)

Repetitive negative thinking (RNT) is an umbrella term that refers to an individual’s tendency to have negative thoughts in an uncontrollable and repetitive manner regardless of their content and temporal focus. RNT is suggested to be a transdiagnostic factor that may be associated with vulnerability for many different psychological disorders. The aim of the present study is to examine the psychometric qualities of Perseverative Thinking Questionnaire (PTQ), which is a scale that assesses non-disorder-specific form of RNT. The data was gathered from 446 Turkish individuals between the ages of 18 and 58 years through a web based data collection method. In addition to PTQ, the participants also completed questionnaires that measure worry, rumination, anxiety, depression, and thought suppression. Two models were tested, and CFA revealed a better fit for the 3-factor model. Results indicated that the scale has satisfactory levels of internal consistency, split-half reliability, and test–retest reliability. Further, correlation analyses showed moderate correlations with measures of worry, rumination, anxiety, and depression; which is indicative of satisfactory levels of both convergent and concurrent validity. In sum, Turkish version of PTQ is a psychometrically sound measure that researchers can utilize in research focusing on transdiagnostic processes.     

Worry and rumination: differential associations with anxious and depressive symptoms and coping behavior

Worry and rumination are closely allied cognitive processes that impact on the experience of anxious and depressive symptoms. Using a prospective design, this study examined overlapping and distinct features of worry and rumination in relation to symptoms and coping behavior in a nonclinical sample of Singaporean college students. Worry and rumination were highly correlated, but they retained distinct components that predicted anxious and depressive symptoms differentially within and across time. Specifically, worry was uniquely associated with anxious and depressive symptoms whereas rumination was uniquely related to depression. In comparison to rumination, worry emerged as the dominant cognitive vulnerability factor that predicted increments in symptoms over time. With regards to coping behavior, low perceived coping effectiveness partially mediated the relation between worry and increases in anxiety and depression. Conversely, rumination uniquely predicted higher disengagement from problems, which resulted in further exacerbation of depressive mood. These results demonstrated not only the distinct features of worry and rumination on coping behavior, but also the different coping pathways by which they differentially impact on subsequent symptoms.     

Relation of Repetitive Thinking Styles with Anxiety and Depression in Patients with Inflammatory Bowel Disease

In this study, we aimed to evaluate the relationship between the repetitive thinking styles and anxiety and depression in patients with inflammatory bowel disease (IBD). One hundred IBD outpatients (39 active and 61 remission) attending the gastroenterology clinic and 100 healthy controls were included.The rumination and worry scores of IBD patients, particularly in their active period, were significantly higher than controls. Additionally, the correlation of rumination and worry with anxiety and depression was statistically significant. Our results suggest that psychological interventions targeting repetitive thinking would alleviate depression and anxiety as well as GI symptoms in people with IBD which should be confirmed by further studies.

     

Perfectionism and negative repetitive thoughts: Examining a multiple mediator model in relation to mindfulness

Perfectionism is known to be associated with various maladaptive outcomes, yet little research has examined mechanisms underlying perfectionism or potential protective factors. This study investigated worry and rumination as mediators between perfectionism and psychological distress in university students (N = 213), and related the multiple mediator model to a five-facet conceptualization of mindfulness. Socially prescribed perfectionism was related to higher levels of distress, including negative affect, depression, anxiety, and stress, while self-oriented perfectionism and other-oriented perfectionism appeared unrelated to distress. Mindfulness facets of acting with awareness, non-judging of inner experience, and to a lesser extent non-reactivity to inner experience, were the strongest independent contributors to perfectionism, negative repetitive thoughts, and distress. Worry and rumination mediated the relationship between socially prescribed perfectionism and negative affect; however, the mediating effect of rumination was absent in those high in mindfulness. These findings suggest that a mindfulness disposition may mitigate distress related to socially prescribed perfectionism by removing the mediating effect of ruminative thought. Future research might explore a mindfulness-training program to target negative repetitive thoughts underlying socially prescribed perfectionism.     

Rumination, worry, cognitive avoidance, and behavioral avoidance: examination of temporal effects

Recently, cross-sectional research has demonstrated that depressive rumination is significantly associated with the tendency to engage in cognitive and behavioral avoidance. This evidence suggests that rumination may be the result of attempts to avoid personally threatening thoughts, in a manner suggested by multiple contemporary theories of worry. This investigation examined the temporal relationship among daily levels of cognitive avoidance, behavioral avoidance, rumination, worry, and negative affect. Seventy-eight adolescents completed baseline questionnaires and then electronically completed daily measures of rumination, worry, behavioral avoidance, and cognitive avoidance, as well as sad and anxious affect for 7 days. Lagged-effect multilevel models indicated that increases in daily sadness were predicted by greater daily rumination and cognitive avoidance. Increases in daily anxiety were predicted by greater daily rumination, worry, and both cognitive and behavioral avoidance. Further, both daily rumination and worry were positively predicted by daily cognitive, but not behavioral, avoidance. Mediation analyses suggested that rumination mediated the effect of cognitive avoidance on both sadness and anxiety. Also, worry mediated the effect of cognitive avoidance on anxiety. Implications for models of avoidance, rumination, and worry are discussed.     

Psychometric Properties of the Response to Anxiety Questionnaire

Recent research highlights the importance of transdiagnostic factors of psychopathology, particularly in understanding comorbidity. Repetitive negative thinking (RNT) is one such factor, which may elucidate anxiety-depression comorbidity. The Response to Anxiety Questionnaire (RAQ) aims to evaluate repetitive negative thinking (RNT) related to anxiety-depression comorbidity, specifically hopelessness and rumination about anxiety symptoms. Anxious hopelessness is negative thoughts about the future due to anxiety symptoms, and anxious rumination includes negative evaluations of the meaning of anxiety symptoms, therefore the current study assessed the RAQ in three studies. We used exploratory and confirmatory factor analysis methodologies to examine the factor structure of the RAQ. In addition, we tested indirect effects of the two factors of RAQ (Rumination and Hopelessness) between anxiety and depression, and tested measure convergent validity. Results of the current study provide additional support for the psychometric properties of the RAQ, suggesting a two factor makeup (hopelessness, rumination), as well as its use in predicting anxiety and depressive symptoms.     

Exploring the Link Between Emotional and Behavioral Dysregulation: A Test of the Emotional Cascade Model

The emotional cascade model (Selby, Anestis, & Joiner, 2008) posits that the link between emotional and behavioral dysregulation may be through emotional cascades, which are repetitive cycles of rumination and negative affect that result in an intensification of emotional distress. Dysregulated behaviors, such as non-suicidal self-injury, are used to reduce aversive emotions and distract the person from ruminative processes. The aim of the present study was to investigate the emotional cascade model in a non-Western sample of Turkish university students. Accordingly, a structural equation model was tested, and the results demonstrated that the emotional cascades were indeed associated to dysregulated behaviors, even when the effect of current symptoms of depression and anxiety on behavioral dysregulation was statistically controlled. Furthermore, thought suppression had a stronger relationship with all symptom patterns as compared to rumination, which may point to a cultural difference. Possible implications of the findings are discussed.     

Distinguishing rumination from worry in clinical insomnia

Research has found that repetitive thought processes, such as worry and rumination, play an important role in several disorders; however, these cognitive processes have not yet been examined in insomnia. This study explores rumination and worry in insomnia by examining: 1) whether those high and low on rumination and worry differ on subjective sleep measures, and 2) whether rumination and worry are distinct processes in insomnia. Participants (N = 242) were diagnosed with an insomnia disorder by sleep experts. Participants completed measures of worry and rumination and maintained a 2-week daily sleep log. Results of a multivariate analysis of variance found no main effect of worry; although high and low ruminators differed on several sleep log indices, including sleep efficiency, wakefulness after sleep onset and sleep quality. Factor analysis supported the idea that rumination and worry are separate constructs. Whereas previous research has focused on worry in insomnia, these findings suggest that rumination is important for understanding sleep disturbance. Further, although rumination and worry are both repetitive thought processes, these results indicate that they are distinct processes within insomnia and should be treated as such. The results are discussed with respect to treatment implications for Cognitive Behavioural Therapy for Insomnia.     

Reciprocal Relations of Worry,Rumination, and Psychopathology Symptoms After Loss: A Prospective Cohort Study

Bereavement can precipitate symptoms of depression, prolonged grief disorder, and posttraumatic stress disorder. Targeting repetitive negative thought (i.e., worry, rumination) in treatment may help reduce post-loss psychopathology. Yet, evidence on longitudinal associations of depressive rumination and worry with post-loss psychopathology symptoms has been mixed and the directions of effects are still unclear. Recently bereaved adults (78% female) completed questionnaires assessing depressive rumination (brooding), worry, and depression, prolonged grief and posttraumatic stress symptoms 11 times in 1.5 month intervals. We applied random-intercept cross-lagged panel models (RICLPMs) to examine reciprocal within-person associations between worry and psychopathology symptoms, between rumination and these symptoms, and between worry and rumination. Main findings were that worry showed reciprocal relationships with psychopathology symptoms (although worry did not consistently predict prolonged grief symptoms). Depressive rumination was predicted by psychopathology symptoms, but not vice versa. Worry showed reciprocal relations with depressive rumination. Findings suggest that worry may be part of a downward spiral, enhancing psychopathology symptoms following loss, whereas depressive rumination is solely a consequence of such symptoms.
