Postponing worrisome thoughts in children: The effects of a postponement intervention on perseverative thoughts, emotions and somatic complaints

Worry Postponement From the Metacognitive Perspective: A Randomized Waitlist-Controlled Trial

Background

Pathological worry is associated with appraisals of worrying as uncontrollable. Worry postponement (WP) with a stimulus control rationale appears to be effective in non-clinical samples. However, preliminary research in participants with generalized anxiety disorder (GAD) does not support its efficacy in reducing negative metacognitions or worry. The aim of this study was to investigate the efficacy of WP with a metacognitive rationale.

Method

Participants with GAD (n = 47) or hypochondriasis (HYP; n = 35) were randomly assigned to either an intervention group (IG) or waitlist (WL). The IG received a two-session long WP intervention aiming at mainly reducing negative metacognitions concerning uncontrollability of worrying. Participants were instructed to postpone their worry process to a predetermined later time during the six days between the two sessions. Participants completed questionnaires of negative metacognitions and worry at pre-assessment, post-assessment, and follow-up.

Results

We observed a significant Time*Group interaction for negative metacognitions and worry. Post-hoc analyses on the total sample and separately for GAD and HYP revealed significantly lower worry scores in the treated GAD sample compared to the WL, representing the only significant effect. In the GAD group, pre-post-effect sizes were small for negative metacognitions and large for worry. Effects persisted to a four-week follow-up.

Conclusion

WP with a metacognitive rationale seems to be effective in reducing worry in participants with GAD. The effectiveness for HYP seems limited, possibly due to the small sample size.

Does workplace telepressure get under the skin? Protocol for an ambulatory assessment study on wellbeing and health-related physiological, experiential, and behavioral concomitants of workplace telepressure

BACKGROUND

The daily working life of many employees requires the use of modern information and communication technology (ICT) devices such as computers, tablets, and smartphones. The double-edged nature of digital work environments has been increasingly highlighted. Benefits such as increased flexibility come at a personal cost. One of the potential downsides is workplace telepressure, i.e., the experience of urge and preoccupation to quickly reply to work-related messages and demands using ICT. There is initial - mainly survey-based-evidence that workplace telepressure may have negative effects on a variety of wellbeing and health outcomes.

AIMS AND HYPOTHESES

Adopting the Effort-Recovery Model and the concept of allostatic load as theoretical frameworks, the present study aims to investigate the hypothesis that workplace telepressure is significantly associated with increased "wear and tear", in the form of more psychosomatic complaints, worse sleep quality (self-reported and actigraphy-based), worse mood, and biological alterations (lower cardiac vagal tone, lower anabolic balance defined as the ratio of salivary dehydroepiandrosterone to salivary cortisol, and higher salivary alpha-amylase). Additionally, the study aims to investigate the hypothesis that connection to work defined as work-related workload and work-related perseverative cognition plays a significant role in the mediation of these relationships.

METHODS

To test our hypotheses, we will conduct an ambulatory assessment study with a convenience sample of 120 healthy workers regularly using ICTs for job communication. For one week, participants will be asked to complete electronic diaries assessing their level of workplace telepressure, psychosomatic complaints, sleep quality, mood, work-related workload, and work-related perseverative cognition. They will also continuously wear the Bittium Faros 180L ECG monitor, the wrist-worn actigraph MotionWatch 8, and perform saliva sampling five times per day.

DISCUSSION

This study will be the most comprehensive ambulatory investigation of workplace telepressure and its psychophysiological concomitants to date and constitutes an important step towards understanding how high levels of workplace telepressure may lead in the long term to secondary alterations (e.g., hypertension, chronic inflammation) and disease (e.g., heart disease). The findings of this study are also anticipated to contribute to guiding the development and implementation of interventions, programs, and policies relevant to employees' digital wellbeing.

Exploring personalized psychotherapy for depression: A system dynamics approach

Depressive disorders are the leading contributor to medical disability, yet only 22% of depressed patients receive adequate treatment in a given year. Response to treatment varies widely among individuals with depression, and poor response to one treatment does not signal poor response to others. In fact, half of patients who do not recover from a first-line psychotherapy will recover from a second option. Attempts to personalize psychotherapy to patient characteristics have produced better outcomes than usual care, but research on personalized psychotherapy is still in its infancy. The present study explores a new method for personalizing psychotherapy for depression through simulation modeling. In this study, we developed a system dynamics simulation model of depression based on one of the major mechanisms of depression in the literature and investigated the trend of depressive symptoms under different conditions and treatments. Our simulation outputs show the importance of individualized services with appropriate timing, and reveal a new method for personalizing psychotherapy to heterogeneous individuals. Future research is needed to expand the model to include additional mechanisms of depression.

Do Worry and Brooding Predict Health Behaviors? A Daily Diary Investigation

BACKGROUND

Meta-analyses have reported associations between perseverative cognition (both worry and brooding) and increased engagement in health-risk behaviors, poorer sleep, and poorer physiological health outcomes.

METHOD

Using a daily diary design, this study investigated the within- and between-person relationships between state and trait perseverative cognition and health behaviors (eating behavior, physical activity, alcohol consumption, and sleep) both cross-sectionally and prospectively. Participants (n = 273, 93% students, M_age = 20.2, SD = 4.11, 93% female) completed morning and evening diaries across 7 consecutive days.

RESULTS

Multilevel modeling analyses revealed that, cross-sectionally, higher levels of state worry were associated with more time spent sitting and higher levels of state brooding predicted less daily walking.

CONCLUSION

Worry and brooding may represent useful intervention targets for improving inactivity and walking levels, respectively.

Social anxiety disorder and emotion regulation problems in adolescents

BACKGROUND

Social anxiety disorder (SAD) in adolescents may be associated with the use of maladaptive emotion regulation (ER) strategies. The present study examined the use of maladaptive and adaptive ER strategies in adolescents with SAD.

METHODS

30 adolescents with SAD (CLIN) and 36 healthy adolescents for the control group (CON) aged between 11 and 16 years were assessed with the standardized questionnaires PHOKI (Phobiefragebogen für Kinder und Jugendliche) for self-reported fears as well as FEEL-KJ (Fragebogen zur Erhebung der Emotionsregulation bei Kindern und Jugendlichen) for different emotion regulation strategies.

RESULTS

Compared to controls, adolescents with SAD used adaptive ER strategies significantly less often, but made use of maladaptive ER strategies significantly more often. There was a significant positive correlation between maladaptive ER and social anxiety in adolescents. Examining group differences of single ER strategy use, the CLIN and CON differed significantly in the use of the adaptive ER strategy reappraisal with CLIN reporting less use of reappraisal than CON. Group differences regarding the maladaptive ER strategies withdrawal and rumination, as well as the adaptive ER strategy problem-solving were found present, with CLIN reporting more use of withdrawal and rumination and less use of problem-solving than CON.

CONCLUSIONS

Promoting adaptive emotion regulation should be a central component of psychotherapy (cognitive behavioral therapy-CBT) for social anxiety in adolescents from the beginning of the therapy process. These findings provide rationale for special therapy programs concentrating on the establishment of different adaptive ER strategies (including reappraisal). As an increased use of maladaptive ER may be associated with SAD in adolescents, it may be paramount to focus on reduction of maladaptive ER (for example withdrawal and rumination) from the beginning of the psychotherapy process. Incorporating more ER components into psychotherapy (CBT) could increase the treatment efficacy. Further investigations of the patterns of emotion regulation in specific anxiety groups like SAD in adolescents is needed to continue to optimize the psychotherapy (CBT) concept.

Application of a worry reduction intervention in a medically unexplained symptoms-analogue student-sample

OBJECTIVE

Worry is an important perpetuating factor of Medically Unexplained Symptoms (MUS). Former research has shown that a worry postponement instruction is effective in reducing Subjective Health Complaints (SHC) in non-clinical samples. This study aimed to (1) replicate these findings in a MUS-analogue student-sample and (2) assess alexithymia as a moderator.

DESIGN

The current study had an experimental design with two waves of data collection: pre- and post-intervention.

MAIN OUTCOME MEASURES

A MUS-analogue student-sample consisting of 114 undergraduate students with high self-reported health worry and a minimum of two doctor visits in the previous year with no current diagnosis for a (chronic or acute) disease were instructed to register their worry frequency and duration eight times per day via an experience sampling-application on their smartphones. The intervention group additionally postponed their worries to a 30-minute period in the evening. SHC were assessed pre- and post-intervention.

RESULTS

The intervention did not have an effect on worry or SHC. Alexithymia did not moderate this effect (p's > .05).

CONCLUSION

Our study did not find evidence for the effectiveness of the worry reduction intervention on SHC in a MUS-analogue student-sample. This finding contributes to several previous studies that have found mixed evidence for the effectiveness of the worry reduction intervention on SHC and suggests that the worry intervention may not be effective in all cases.

Stopping the Train of Thought: A Pilot Study Using an Ecological Momentary Intervention with Twice-Daily Exposure to Natural versus Urban Scenes to Lower Stress and Rumination

BACKGROUND

Stress, and specifically perseverative cognition, is considered to have considerable detrimental effects on mental and physical health. Interventions that can offer temporary stress relief could, therefore, bring considerable health benefits. Previous research has pointed to stress-reducing effects of exposure to nature after acute stressors, but has not yet investigated effects in the realm of everyday life. The present pilot study explores whether an ecological momentary intervention using exposure to natural images could be effective in lowering stress and improve mood.

METHODS

Fifteen participants (12 females) scoring above threshold on stress, depression, or anxiety completed two study periods of 6 days. They watched an urban (control) or natural slideshow twice daily. Using Ecological Momentary Assessment, effects on mood, and stress-related complaints were measured in everyday life.

RESULTS

Compliance to the study protocol was high, especially in the first week, with slightly more videos watched in the morning than in the evening. We found indications of improvements in mood, self-reported worrying (but not stress levels), and heart rate.

CONCLUSIONS

The results suggest that twice-daily exposure to restorative visual content could be a viable Ecological Momentary Intervention, with the potential to reduce self-reported worry, lower autonomic activity, and increase positive affect.

Gender Invariance and Psychometric Properties of the Nonproductive Thoughts Questionnaire for Children

Perseverative cognitions—rumination and worry—can contribute to mental and somatic health problems in adolescence. Girls usually report stronger rumination or worry than boys even in earlier years across the development age spectrum. Our aim was to test the gender invariance and psychometric properties of the Nonproductive Thoughts Questionnaire for Children (NPTQ-C). Study 1 involved 1,572 students (mean age = 15.39 years, SD = 2.26; 49% boy) recruited representatively from local schools. We applied confirmatory factor analysis (CFA) to test the measurement model of perseverative cognitions. The gender invariance of the measurement model and the convergent validity were analyzed as well with CFA with covariates model. The original one-factor structure of NPTQ-C was supported in our adolescent sample. Gender invariance was also confirmed. The NPTQ-C indicated high convergent validity: showing positive correlations with emotional instability and emotional symptoms. In Study 2 (385 students; mean age = 16.05; SD = 1.23; 34% boy), we tested the construct validity of NPTQ-C. The applied CFA with covariates model supported the construct validity. In summary, NPTQ-C proved to be a good instrument for measuring ruminative and worrying thoughts of adolescents, which reliably measures perseverative cognitions across genders.

Ever at the ready for events that never happen

Stress, whether daily stress, work stress or traumatic stress, is unhealthy. This lecture covers three recent theoretical approaches in explaining the mechanisms underlying the influence of psychological stress on somatic health. It is argued that stress research should focus less on stressors themselves and put more emphasis on prolonged stress responses. Three mechanisms are identified that cause this unhealthy prolonged stress response: first, the partly-proven mechanism of perseverative cognition; second, the mechanism of unconscious stress, which is currently being explored; and third, the notion of the stress response being a default response that is inhibited only when safety is perceived. All three mechanisms are deeply rooted in millions of years of our evolution. Although the dangers of the past have virtually disappeared, many of us remain ever at the ready for events that never happen.

Reducing worry and subjective health complaints: A randomized trial of an internet-delivered worry postponement intervention

OBJECTIVES

Several studies have shown that perseverative, worrisome thoughts are prospectively related to subjective health complaints (SHC) and that a short worry postponement intervention can decrease these complaints. As SHC and worry are prevalent and costly, we tested whether the intervention can be offered online to reduce these complaints in the general population.

DESIGN

A randomized parallel-group trial was conducted with self-selected participants from the general population.

METHODS

Via the research website, 996 participants were instructed to register their worrying for 6 consecutive days. The intervention group was instructed to postpone worry to a special 30-min period in the early evening. The Subjective Health Complaints inventory, as administered before and after the intervention, and daily worry frequency and duration were considered the primary outcomes.

RESULTS

Three hundred and sixty-one participants completed the study. Contrary to our expectation, the registration group (n = 188) did not differ from the intervention group (n = 163) in SHC (ηp² = .000, CI [0.000-0.003]), or in worry frequency or duration. Nevertheless, the different worry parameters were moderately related to SHC (r between .238 and .340, p ≤ .001).

CONCLUSIONS

In contrast to previous studies using pen-and-pencil versions of the worry postponement intervention, this study suggests that a direct online implementation was not effective in reducing SHC and worry. Overall, participants had high trait worry levels and reported difficulty with postponing worrying. Reducing SHC and worries via the Internet might require more elaborate interventions that better incorporate the advantages of delivering interventions online.

STATEMENT OF CONTRIBUTION

What is already known on this subject? The perseverative cognition hypothesis argues that perseverative cognition, such as worry and rumination, acts as a mediator by which psychosocial stress may produce negative health effects. Prior research has indeed shown that worry and subjective health complaints (SHC) are prospectively related, but causality studies - that is, showing that changes in worry induce changes in health outcomes - are scarce and have mainly been conducted in young samples. These studies showed that reducing worry, using a worry postponement intervention, can reduce daily worrying and SHC. What does this study add? Trait and daily worrying are associated with SHC. An online worry postponement intervention is ineffective in reducing worry and SHC. Paper-and-pencil interventions cannot directly be used as online interventions.

Perseverative thoughts and subjective health complaints in adolescence: Mediating effects of perceived stress and negative affects

Stable tendency to perseverative thoughts such as trait rumination and worry can influence somatic health. The purpose of the study was to investigate the relationship between perseverative thoughts and somatic complaints, and the possible mediating effects of perceived stress, negative and positive affectivity in adolescence. Having an acute or a chronic condition was also assessed to be controlled for and to reveal their effects on symptom reporting. Three hundred and six adolescents from 7th to 12th grade with mean age of 16.33 (SD = 1.29) participated in the study. Mediation analysis suggested that impact of trait-like perseverative thoughts on complaints were mediated by perceived stress and negative affectivity. Having an acute condition had also an effect on symptom reporting through increased negative affectivity. Our results highlight that ruminations or worry as stable intrapersonal characteristics are relevant processes in health and can be potential targets in prevention programmes in adolescence.

Cognitive, behavioral, and autonomic correlates of mind wandering and perseverative cognition in major depression

Autonomic dysregulation has been hypothesized to play a role in the relationships between psychopathology and cardiovascular risk. An important transdiagnostic factor that has been associated with autonomic dysfunction is perseverative cognition (PC), mainly present in Major Depressive Disorder (MDD) in the form of rumination. As the ability to adaptively let our mind wander without ruminating is critical to mental health, this study aimed to examine the autonomic concomitants of functional vs. dysfunctional intrusive thoughts in MDD. Ambulatory heart rate (HR) and variability (HRV) of 18 MDD subjects and 18 healthy controls were recorded for 24 h. Approximately every 30 min during waking hours subjects reported their ongoing thoughts and moods using electronic diaries. Random regression models were performed. Compared to controls, MDD subjects were more often caught during episodes of PC. In both groups, PC required more effort to be inhibited and interfered more with ongoing activities compared to mind wandering (MW) (ps < 0.0001). This cognitive rigidity was mirrored by autonomic inflexibility, as PC was characterized by lower HRV (p < 0.0001) compared to MW. A worse mood was reported by MDD patients compared to controls, independently of their ongoing cognitive process. Controls, however, showed the highest mood worsening during PC compared to being on task and MW. HRV during rumination correlated with self-reported somatic symptoms on the same day and several dispositional traits. MDD subjects showed lower HRV during sleep, which correlated with hopelessness rumination. Results show that PC is associated with autonomic dysfunctions in both healthy and MDD subjects. Understanding when spontaneous thought is adaptive and when it is not may clarify its role in the etiology of mood disorders, shedding light on the still unexplained association between psychopathology, chronic stress, and risk for health.

Does unconscious stress play a role in prolonged cardiovascular stress recovery?

According to recent insights, humans might not be aware of a substantial part of their cognitive stress representations while these still have prolonged physiological effects. 'Unconscious stress' can be measured by implicit affect (IA) tests. It was shown that IA predicts physiological stress responses, in fact better than explicit ('conscious') affect. It is not known yet whether IA is associated with concurrent prolonged stress responses. In two studies (n = 62 and 123), anger harassment was used to induce stress. Blood pressure (BP) and heart rate (HR) were measured continuously. During BP and HR recovery, IA was measured by an 'anger' version of the implicit association test (IAT) or the implicit positive and negative affect test (IPANAT). Blood pressure and HR increased during anger harassment and recovery afterwards. When using the IPANAT BP recovery levels were lower when positive IA was high and higher when negative IA was high, independent of explicit affect and rumination. These results were not found using the IAT. These results provide preliminary evidence that physiological stress recovery is associated with IA. This is in line with the theory that unconscious stress is responsible for a-possibly considerable-part of unhealthy prolonged stress-related physiological activity.

Repetitive thought impairs sleep quality: an experience sampling study

Although previous research has suggested that presleep negative cognitive activities are associated with poor sleep quality, there is little evidence regarding the association between negative thoughts and sleep in real-life settings. The present study used experience sampling and long-term sleep monitoring with actigraphy to investigate the relationships among negative repetitive thought, mood, and sleep problems. During a 1-week sampling period, 43 undergraduate students recorded their thought content and mood eight times a day at semirandom intervals. In addition to these subjective reports, participants wore actigraphs on their wrists in order to measure sleep parameters. Analyses using multilevel modeling showed that repetitive thought in the evening was significantly associated with longer sleep-onset latency, decreased sleep efficiency, and reduced total sleep time. Furthermore, impaired sleep quality was significantly associated with reduced positive affect the next morning, and decreased positive affect was indirectly associated with increased repetitive thought in the evening. These findings suggest the existence of a self-reinforcing cycle involving repetitive thought, mood, and impaired sleep quality, highlighting the importance of cognitive and emotional factors in enhancement and maintenance of good-quality sleep.

Mind magic: a pilot study of preventive mind-body-based stress reduction in behaviorally inhibited and activated children

PURPOSE OF STUDY

The aim of this pilot study was to examine a mind-body-based preventive intervention program and to determine relationships between children's behavioral inhibition system (BIS) and behavioral activation system, stress, and stress reduction after the program.

DESIGN OF STUDY

Children participated in the program (n=30) or in a control condition (n=24). They filled out questionnaires before and after the program and reported their levels of stress before and after each of the five sessions.

METHOD

The program consisted of weekly sessions. Each session incorporated yoga postures, visualization, and social exercises. Breathing techniques were integrated.

FINDINGS

Stress reductions were only seen in the intervention group and mainly in children with high BIS--irrespective of their behavioral activation system.

CONCLUSION

The results demonstrate that children with high BIS may benefit from a mind-body-based stress reduction program.

Conscious and unconscious perseverative cognition: is a large part of prolonged physiological activity due to unconscious stress?

Prolonged physiological activity is believed to be a key factor mediating between stress and later disease outcomes. Few studies, however, have investigated the crucial psychological factors that cause prolonged activity. This article proposes that conscious as well as unconscious perseverative cognition are the critical factors. Perseverative cognition indicates repetitive or sustained activation of cognitive representations of past stressful events or feared events in the future. In daily life, most prolonged physiological activity is not due to stressful events but to perseverative cognition about them. We and others have already found evidence that conscious perseverative cognition, i.e., worry, has physiological effects, in both laboratory and real life settings, and that perseverative cognition mediates prolonged responses to stressful events. Yet, there are convincing reasons to expect that unconscious perseverative cognition has an even larger role in stress-related prolonged activity. Firstly, since the greater part of cognitive processing operates without awareness, a considerable part of perseverative cognition is likely to be unconscious too. People may not be aware of most of their stress-related cognitive processes. Secondly, our recent studies have shown that increased activity of the autonomic nervous system continues after conscious perseverative cognition has stopped: It goes on for several hours and even during sleep. This and several other findings suggest that a considerable part of increased physiological activity may be due to unconscious perseverative cognition. The article closes with suggesting methods to test unconscious perseverative cognition and ways to change it, and concludes with stating that the notion of unconscious perseverative cognition potentially opens an entirely new area within stress research.

Markers of chronic stress: prolonged physiological activation and (un)conscious perseverative cognition

In daily life, not stressful events themselves but their sustained cognitive representation is likely to cause prolonged physiological activity, which is believed to lead to a pathogenic state and finally somatic disease. The typically human ability to make cognitive representations of past stressful events (rumination) or feared events in the future (worry) is called perseverative cognition (PC). PC is associated with increased activity in various bodily systems, and there is emerging evidence that it mediates the prolonged effects of stressors on physiology and on disease. Yet, there are strong reasons to believe that people may not be aware of the greater part of their stress-related cognitive processes, while several studies suggest that these processes may still cause increased physiological activity, during sleep as well as during waking. This may imply that unconscious PC is an even more important source of prolonged stress-related activity than conscious PC. Thus, 'unconscious stress' research has the potential to become a new important area and may yield new important markers of chronic stress.
