Metacognitions, anxiety, and distress related to motor fluctuations in Parkinson's disease

The Role of Metacognition in the Prediction of Depressive and Anxiety Symptoms in Chronically Ill Patients

INTRODUCTION

Cancer, diabetes, and heart diseases are frequent causes of depression and anxiety. The study explored the metacognitive beliefs manifested by chronically ill patients and the presence of depressive or anxiety symptoms and the predictive role of metacognition in both.

METHODS

A total of 254 chronically ill patients participated in the study. The Metacognitive Questionnaire was used to measure the patients' metacognitive beliefs, whereas the Hospital Anxiety and Depression Scale was applied to evaluate their psychopathological symptoms. A correlation analysis was performed to explore the relationships between metacognition and psychopathological symptoms. Regression analyses were conducted to examine the predictive role of metacognition in anxiety and depression.

RESULTS

The Negative Beliefs about Uncontrollability and Danger scale correlated with both anxiety and depression scales, and the Cognitive Confidence scale correlated with the depression scale. Linear regression analyses indicated that metacognitive beliefs were responsible for 32.2% of the variance of anxiety symptoms among all the chronically ill. Metacognitive beliefs accounted for 48.8% of the variance in anxiety symptoms and 36.6% in depressive symptoms among diabetes patients.

CONCLUSIONS

There are specific correlations between psychopathological symptoms and metacognition among chronically ill patients. Metacognitions have a moderate role in developing and sustaining anxiety and depressive symptoms.

Metacognitions in patients with chronic obstructive pulmonary disease: a psychometric study of the metacognitions questionnaire-30

The metacognitions questionnaire-30 (MCQ-30) was developed for the assessment of metacognitive beliefs and processes that are central components of the metacognitive model of emotional disorders. Anxiety and depression commonly occur in patients with chronic obstructive pulmonary disease (COPD). Testing such a model for anxiety and depression in patients with COPD is warranted. However, the psychometric properties of the MCQ-30 in COPD patients are unknown. Therefore, in this study we aimed to examine these properties in COPD patients. The MCQ-30 was administered to 203 COPD patients referred to a rehabilitation unit in respiratory medicine. Confirmatory factor analysis (CFA) was used to test the five-factor as well as the bi-factor models of MCQ-30. Exploratory factor analyses were also performed. Both models did not meet the criteria for an acceptable fit on Comparative Fit Index (CFI) of 0.810 and 0.858 vs. criterion of ≥0.9, but the Root Mean Square Error of Approximation (RMSEA) criterion ≤0.08 was acceptable for both models with RMSEA = 0.074 and 0.066, respectively. The factors were mostly moderately correlated (0.41-0.58) with acceptable reliability coefficients (0.73-0.87). The exploratory factor analysis identified three of the five factors originally described in the five-factor model of the MCQ-30. These data show that the factor structure of the MCQ-30 appears to differ from that of the original instrument in COPD patients and further studies are needed to confirm its validity and reliability in this patient group.

The role of uncertainty intolerance in adjusting to long-term physical health conditions: A systematic review

Long-term physical health conditions (LTPHCs) are associated with poorer psychological well-being, quality of life, and longevity. Additionally, individuals with LTPHCs report uncertainty in terms of condition aetiology, course, treatment, and ability to engage in life. An individual's dispositional ability to tolerate uncertainty-or difficulty to endure the unknown-is termed intolerance of uncertainty (IU), and may play a pivotal role in their adjustment to a LTPHC. Consequently, the current review sought to investigate the relationship between IU and health-related outcomes, including physical symptoms, psychological ramifications, self-management, and treatment adherence in individuals with LTPHCs. A systematic search was conducted for papers published from inception until 27 May 2022 using the databases PsycINFO, PubMed (MEDLINE), CINAHL Plus, PsycARTICLES, and Web of Science. Thirty-one studies (N = 6,201) met the inclusion criteria. Results indicated that higher levels of IU were associated with worse psychological well-being outcomes and poorer quality of life, though impacts on self-management were less clear. With the exception of one study (which looked at IU in children), no differences in IU were observed between patients and healthy controls. Although findings highlight the importance of investigating IU related to LTPHCs, the heterogeneity and limitations of the existing literature preclude definite conclusions. Future longitudinal and experimental research is required to investigate how IU interacts with additional psychological constructs and disease variables to predict individuals' adjustment to living with a LTPHC.

Effects of Mindfulness Meditation on Doctors' Mindfulness, Patient Safety Culture, Patient Safety Competency and Adverse Event

OBJECTIVE

This study investigated the effects of mindfulness meditation on doctors' mindfulness, patient safety culture, patient safety competency, and adverse events.

METHODS

We recruited 91 doctors from a hospital in China and randomized them to mindfulness meditation group (n = 46) and a waiting control group (n = 45). The mindfulness meditation group underwent an 8-week mindfulness meditation intervention, while the control group underwent no intervention. We measured four main variables (mindfulness, patient safety culture, patient safety competency, and adverse event) before and after the mindfulness meditation intervention.

RESULTS

In the experimental group, mindfulness, patient safety culture and patient safety competency were significantly higher compared with those of the control group. In the control group, there were no significant differences in any of the three variables between the pre-test and post-test. Adverse events in the experimental group were significantly lower than in the control group.

CONCLUSIONS

The intervention of mindfulness meditation significantly improved the level of mindfulness, patient safety culture and patient safety competency. During the mindfulness meditation intervention, the rate of adverse events in the meditation group was also significantly lower than in the control group. As a simple and effective intervention, mindfulness meditation plays a positive role in improving patient safety and has certain promotional value.

Graph Theory on Brain Cortical Sources in Parkinson's Disease: The Analysis of 'Small World' Organization from EEG

Parkinson’s disease (PD) is the second most common neurodegenerative disease in the elderly population. Similarly to other neurodegenerative diseases, the early diagnosis of PD is quite difficult. The current pilot study aimed to explore the differences in brain connectivity between PD and NOrmal eLDerly (Nold) subjects to evaluate whether connectivity analysis may speed up and support early diagnosis. A total of 26 resting state EEGs were analyzed from 13 PD patients and 13 age-matched Nold subjects, applying to cortical reconstructions the graph theory analyses, a mathematical representation of brain architecture. Results showed that PD patients presented a more ordered structure at slow-frequency EEG rhythms (lower value of SW) than Nold subjects, particularly in the theta band, whereas in the high-frequency alpha, PD patients presented more random organization (higher SW) than Nold subjects. The current results suggest that PD could globally modulate the cortical connectivity of the brain, modifying the functional network organization and resulting in motor and non-motor signs. Future studies could validate whether such an approach, based on a low-cost and non-invasive technique, could be useful for early diagnosis, for the follow-up of PD progression, as well as for evaluating pharmacological and neurorehabilitation treatments.

The psychological correlates of fatigue in Parkinson's disease: Contribution of maladaptive metacognitive beliefs

INTRODUCTION

Psychological factors can underlie fatigue in neurological disorders, but its relationship to fatigue in Parkinson's disease (PD) has not been explored. We assessed the association between maladaptive metacognitive beliefs and presence of fatigue in PD.

METHODS

Ninety-eight consecutive outpatients with PD (61% male; median age: 66.50 years) were assessed in terms of demographic, clinical, medication treatment, cognitive, or behavioural characteristics including metacognitive beliefs (Metacognitions Questionnaire-30 or MCQ). Fatigue was ascertained by PD-related diagnostic criteria. Univariate statistical approach (Mann-Whitney and Pearson chi-square tests) was used to compare PD patients with (f-PD) or without (nf-PD) fatigue in terms of demographic, clinical, medication treatment, cognitive, behavioural, and metacognitive measures.

RESULTS

Twenty-one PD patients (21%) displayed fatigue. The f-PD group scored higher on the MCQ-total score, MCQ-Cognitive Confidence subscale, and all behavioral measures (p_s < 0.01) relative to nf-PD. They also had a more advanced Hoehn and Yahr stage and Unified Parkinson's Disease Rating Scale-III score.

CONCLUSION

Maladaptive metacognitive beliefs such as the lack of cognitive confidence may play a key role to trigger and maintain fatigue in PD. Future studies, using a multivariate statistical approach, are needed to confirm these preliminary findings in a larger sample of patients with fatigue and to assess if modification of such metacognitive beliefs has the potential to ameliorate fatigue in PD.

The contribution of cognitive behavioural factors to social anxiety in Parkinson's disease

BACKGROUND

Social anxiety is prevalent in idiopathic Parkinson's disease but why this is, is not yet well understood. Social cognitions, safety-seeking behaviours and internally focused attention are all known to predict social anxiety in the general population. These associated factors have not yet been explored in idiopathic Parkinson's disease, where disease severity and motor symptoms might also influence the experience of social anxiety.

AIMS

This study aimed to explore the relationship between cognitive behavioural factors and social anxiety in Parkinson's disease.

METHOD

Using a cross-sectional design, 124 people with Parkinson's disease completed self-report questionnaires including measures of Parkinson's disease severity, social anxiety, negative social cognitions, safety-seeking behaviours, internally focused attention, anxiety and depression.

RESULTS

The final regression model accounted for 71.6% of variance in social anxiety. Cognitive behavioural variables accounted for the largest magnitude of unique variance (43.5%). Sex, anxiety and depression accounted for 23.4%, and Parkinson non-motor symptom severity for 4.7%. Negative social cognitions and safety-seeking behaviours were statistically significant predictors, while an internal focus of attention was not.

CONCLUSIONS

Social anxiety in Parkinson's disease is associated with negative social cognitions and safety-seeking behaviours. Findings indicate the need for further research into cognitive behavioural approaches to social anxiety in Parkinson's disease.

The Association Between Maladaptive Metacognitive Beliefs and Emotional Distress in People Living With Amyotrophic Lateral Sclerosis

OBJECTIVE

Approximately half of all people living with amyotrophic lateral sclerosis (ALS) experience persistent or recurrent emotional distress, yet little is known about the psychological processes that maintain emotional distress in this population. The self-regulatory executive functioning (S-REF) model specifies that maladaptive metacognitive beliefs and processes are central to the development and maintenance of emotional distress. This study explored whether maladaptive metacognitive beliefs are associated with emotional distress after controlling for demographic factors, time since diagnosis, and current level of physical functioning.

DESIGN

In a cross-sectional design, 75 adults with a diagnosis of ALS completed self-report questionnaires. Participants had a mean age of 60.40 years, mean duration of symptoms 63.92 months, and male:female gender ratio of 14:11.

MAIN OUTCOME MEASURES

Questionnaires assessed emotional distress (HADS, adapted for ALS), physical functioning (ALSFRS-R), repetitive negative thinking (RTQ-10), metacognitive beliefs (MCQ-30), and demographic factors.

RESULTS

Maladaptive metacognitive beliefs explained additional variance in emotional distress after controlling for age, gender, time since diagnosis, physical functioning, and repetitive negative thinking. Repetitive negative thinking partially mediated the relationships between positive and negative metacognitive beliefs and emotional distress.

CONCLUSIONS

These data support the utility of the metacognitive model in understanding emotional distress in people with ALS. Examination of the temporal relationship between maladaptive metacognitive beliefs and emotional distress in people living with ALS may help to guide the development of therapeutic approaches.

Risk factors for neuropsychiatric symptoms in patients with Parkinson's disease during COVID-19 pandemic in Japan

The worsening of neuropsychiatric symptoms such as depression, anxiety, and insomnia in patients with Parkinson’s disease (PD) has been a concern during the COVID-19 pandemic, because most people worked in self-isolation for fear of infection. We aimed to clarify the impact of social restrictions imposed due to the COVID-19 pandemic on neuropsychiatric symptoms in PD patients and to identify risk factors associated with these symptoms. A cross-sectional, hospital-based survey was conducted from April 22, 2020 to May 15, 2020. PD patients and their family members were asked to complete paper-based questionnaires about neuropsychiatric symptoms by mail. PD patients were evaluated for motor symptoms using MDS-UPDRS part 2 by telephone interview. A total of 71 responders (39 PD patients and 32 controls) completed the study. Although there was no difference in the age distribution, the rate of females was significantly lower in PD patients (35%) than controls (84%) (P < 0.001). Participants with clinical depression (PHQ-9 score ≥ 10) were more common in PD patients (39%) than controls (6%) (P = 0.002). Multivariate logistic regression analysis revealed that an MDS-UPDRS part 2 score was correlated with the presence of clinical depression (PHQ-9 score ≥ 10) and clinical anxiety (GAD-7 score ≥ 7) (clinical depression: OR, 1.31; 95% CI, 1.04–1.66; P = 0.025; clinical anxiety: OR, 1.36; 95% CI, 1.07–1.72; P = 0.013). In the presence of social restrictions, more attention needs to be paid to the neuropsychiatric complications of PD patients, especially those with more severe motor symptoms.

Tinnitus and Metacognitive Beliefs-Results of a Cross-Sectional Observational Study

Recent research has highlighted the role of metacognitions as a moderator for psychological distress in patients with chronic diseases. The present study investigates the role of metacognitions and worry in the association between tinnitus distress, anxiety, and depression. A cross-sectional study was carried out with a sample of tinnitus-outpatients who completed the Tinnitus-Handicap Inventory, Beck Anxiety Inventory, Beck Depression Inventory, Metacognition Questionnaire-30, Penn-State-Worry-Questionnaire. Associations of metacognitions, worries, tinnitus distress, anxiety and depression were investigated using structural equation models (SEMs). A sample of n = 107 patients was included in the study. In the first SEM, tinnitus distress significantly predicted depression (β = 0.68, p < 0.001) and anxiety (β = 0.47, p < 0.001). In the second model, worries and meta-cognitions were added as moderators. The explained variance substantially increased for depression (46 to 53%) and anxiety (22 to 35%) and the association of tinnitus distress with depression (β = 0.57, p < 0.001) and anxiety was weakened (β = 0.32, p < 0.001). Negative beliefs significantly predicted worries (β = 0.51, p < 0.001) and explained 41% of its variance. A good model fit for the final model was found (comparative fit index (CFI) = 0.98; (Tucker Lewis index) TLI = 0.96; root mean square error of approximation (RMSEA) = 0.067). Anxiety and depression in tinnitus patients might be influenced by worries, which is mainly predicted by negative beliefs about uncontrollability and danger of worries. Thus, psychotherapeutic approaches focused on alterations of metacognitions in patients with tinnitus should be investigated in future studies.3 (List three to ten pertinent keywords specific to the article yet reasonably common within the subject discipline.)

Metacognitive beliefs and their relationship with anxiety and depression in physical illnesses: A systematic review

Anxiety and depression are common among patients with chronic physical illnesses and have a significant impact on morbidity, quality of life, and health service utilisation. Psychological treatment of anxiety and depression has small to moderate efficacy in this group and is not commonly based on a model of causal mechanisms. A novel approach to understanding and improving mental health outcomes in physical illnesses is needed. One approach may be to explore the role of metacognitive beliefs which are reliably associated with anxiety and depression in individuals with mental health difficulties. The current systematic review aimed to evaluate the contribution of metacognitive beliefs to anxiety and depression across physical illnesses. Systematic searches were conducted on Web of Science, PsychINFO, MEDLINE, Embase, and CINAHL of studies published between 1997 and January 2019. 13 eligible studies were identified that in sum comprised 2851 participants. Metacognitive beliefs were found to have reliable, moderate, positive and significant associations with anxiety and depression symptoms across a range of physical illnesses. There appeared to be commonality and some specificity in the relationships. Negative metacognitive beliefs concerned with uncontrollability and danger of worry were associated with both anxiety and depression across all physical illnesses assessed, whilst more specific associations emerged for individual medical conditions where positive beliefs about worry, cognitive confidence and cognitive self-consciousness were unique correlates. Negative metacognitive beliefs of uncontrollability and danger significantly and positively predicted symptoms of anxiety and depression after controlling for factors including age, gender, disease factors and cognition (illness perceptions and intolerance of uncertainty). The results suggest that the metacognitive model of psychological disorder is applicable to psychological symptoms of anxiety and depression across a range of chronic medical conditions, implying that metacognitive therapy might be helpful in improving outcomes in multiple morbidities that involve poor mental and medical health.

Metacognitive Therapy for Adjustment Disorder in a Patient With Newly Diagnosed Pulmonary Arterial Hypertension: A Case Report

Adjustment disorders (ADs) belong to the worldwide most diagnosed mental disorders and are particularly frequent in patients with an underlying physical illness. Pulmonary arterial hypertension (PAH) is a severe and disabling disease, which significantly impacts on quality of life and has high mortality rates. The authors here present the case of a young female who developed a severe adjustment disorder with both anxious and depressive symptoms after a diagnosis of PAH requiring intensive care treatment due to right heart failure. Psychosocial functioning was severely impaired, and physical health reduced. Following hemodynamic stabilization and the establishment of PAH treatment, the patient was admitted to the Department of Psychiatry, Social Psychiatry and Psychotherapy and received metacognitive therapy (MCT). AD with mixed anxiety and depressed mood was diagnosed according to DSM-V criteria. At the start of treatment, she reported significant mental distress, indicated by a total sum score of the Hospital Anxiety and Depression Scale (HADS) of 20 points. The 6-min walking distance was only 358 m before the patient was exhausted. She then was treated with MCT without further psychopharmacological drugs. After only four MCT sessions, she fully remitted from AD which was accompanied by an 11-point reduction in the HADS (to 9 points). MCT specific scores also improved (MCQ-30 sum score decreased from 77 to 35). Notably, physical capacity improved as well, documented by an improved walking distance (439 m; +22%). This is the first case of a patient with AD in the context of PAH treated with MCT. The case report suggests that MCT is a possible psychotherapeutic treatment option for AD in the context of a potentially life-threatening disease. The study design does not permit an attribution of outcome to MCT but it suggests MCT is a potentially viable and acceptable treatment option.

A Systematic Review of Metacognitive Beliefs in Chronic Medical Conditions

Background: Psychological functioning plays an important role in medical conditions and impacts patients' quality of life. Previously, many studies have highlighted the association of metacognition to both the development and maintenance of emotional disorders. Recently, several researchers pointed out the relevant role of dysfunctional metacognitive beliefs in the context of chronic diseases. Hence, dysfunctional metacognitive beliefs could be directly related to anxiety and depression, regardless of the medical condition's expression. The aim of this systematic review was to summarize the available evidence regarding the association of metacognition with anxiety, depression, and perceived quality of life, in the context of medical conditions, according to Wells' theory.

Methods: A systematic review based on electronic bibliographic databases (PsycINFO, PubMed, Scopus, Web of Science, and Web of Knowledge) of scientific literature was carried out. Studies involving patients evaluated in clinical settings were included in the analysis.

Results: Our findings indicated that metacognition appears to be related to anxiety, depression, and quality of life in patients with medical chronic conditions. Therefore, dysfunctional metacognitive beliefs might be a relevant factor associated with the process of adapting to illness.

Conclusions: The additional evaluation of metacognitive factors in the context of several medical chronic conditions appears valuable. Due to the rising interest in the study of metacognition, suggestions for future research have also been provided.

Testing relationships between metacognitive beliefs, anxiety and depression in cardiac and cancer patients: Are they transdiagnostic?

OBJECTIVE

Anxiety and depression symptoms are common in patients with physical health conditions. In the metacognitive model, beliefs about cognition (metacognitions) are a key factor in the development and maintenance of anxiety and depression. The current study evaluated if metacognitions predict anxiety and/or depression symptoms and if differential or common patterns of relationships exist across cardiac and cancer patients.

METHOD

A secondary data analysis with 102 cardiac patients and 105 patients with breast or prostate cancer were included. Participants were drawn from two studies, Wells et al. [1] and Cook et al. [2]. All patients reported at least mild anxiety or depression symptoms. Patients completed the Metacognitions Questionnaire 30 (MCQ-30) and the Hospital Anxiety and Depression Scale (HADS). Hierarchical linear regressions evaluated metacognitive predictors of anxiety and depression across the groups.

RESULTS

The results of regression analyses controlling for a range of demographics and testing for effect of illness type showed that uncontrollability and danger and positive beliefs were common and independent predictors of anxiety in both groups. There was one positive bi-variate association between metacognitive beliefs (uncontrollability and danger) and depressive symptoms.

CONCLUSIONS

Findings support the metacognitive model, suggesting that a common set of metacognitive factors contribute to psychological distress, particularly anxiety. Uncontrollability and danger metacognitions and positive beliefs about worry appear to make independent contributions to anxiety irrespective of type of physical illness. While metacognitive beliefs were not reliably associated with depressive symptoms this may be because the current sample exhibited low depression scores.

Cardiac Rehabilitation Patients' Accounts of Their Emotional Distress and Psychological Needs: A Qualitative Study

Background Psychological distress is prevalent among patients with cardiovascular disease and is linked to increased risk of future cardiac events. Cardiac rehabilitation (CR) is widely recommended for treating psychological distress but has been of limited benefit. This study aims to understand how distressed cardiac patients describe their emotional needs and the response of CR. Methods and Results A qualitative descriptive study was conducted with 46 patients who screened positively for anxiety and/or depression. Semi-structured interviews were held, and data were analyzed using a constant comparative approach. Patients described low mood and diverse concerns, including threat of another cardiac event, restrictions on their lives, and problems unrelated to their health. Patients described worrying constantly about these concerns, worrying about their worry, and feeling that worry was uncontrollable and harmful. Patients wanted to "get back to normal" but lacked any sense of how to achieve this and were reluctant to discuss their worries with CR staff. They hoped to recover over time, meanwhile seeking reassurance that they were responding "normally." Patients were mostly dismissive of psychological techniques used in CR. Conclusions These findings expose a conundrum. Distressed CR patients have diverse worries but do not generally want to discuss them, so they invest hopes for feeling better in time passing and reassurance. An intervention acceptable to CR patients would allow them to address diverse worries but without having to share the content of worries, would have "face validity," and would address patients' worry about worry. Metacognitive therapy is an intervention that might be suitable. Clinical Trial Registration URL: https://www.clinicaltrials.gov. Unique identifier: NCT02420431.

Cognitive behavioral therapy improves diverse profiles of depressive symptoms in Parkinson's disease

OBJECTIVE

Depression is among the most common and debilitating nonmotor complaints in Parkinson's disease (PD), yet there is a paucity of controlled research to guide treatment. Little research has focused on the extent to which specific depressive symptom profiles may dictate unique clinical recommendations to ultimately improve treatment outcomes. The current study examined the impact of cognitive behavioral therapy (CBT) on different types of depressive symptoms in PD. It was hypothesized that the cognitive (eg, guilt, rumination, and negative attitudes towards self) and behavioral (eg, avoidance and procrastination) symptoms targeted most intensively by the treatment protocol would show the most robust response. The extent to which stabilized antidepressant use moderated specific symptom change was examined on an exploratory basis.

METHOD

Eighty depressed people with PD participated in a randomized controlled trial of CBT plus clinical management, versus clinical management only. Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI) subscale scores, reflecting depressive symptom heterogeneity in PD, were the focus of this investigation.

RESULTS

CBT response was associated with significant improvements in mood, sleep, anxiety, and somatic symptoms (HAMD), and negative attitudes toward self, performance impairment, and somatic symptoms (BDI). As hypothesized, the largest effect sizes were observed for cognitive and behavioral (vs somatic) symptoms of depression. Stabilized antidepressant use moderated the effect of CBT on somatic complaints (HAMD and BDI).

CONCLUSIONS

CBT may improve a diverse array of depressive symptoms in PD. Cognitive and behavioral (vs somatic) symptoms showed the greatest change. Combining CBT with antidepressants may help optimize the management of somatic complaints in depression in PD (dPD).

An evaluation of the contribution of maladaptive attitudes specific to motherhood and metacognitions in perinatal depression

The cognitive model of depression suggests that dysfunctional attitudes represent vulnerability towards developing depression. The metacognitive model suggests that metacognitions may play a more important role in predicting depression, compared to cognitions. We tested the relative contribution of dysfunctional attitudes and metacognitions, and their interrelationship, in predicting perinatal depressive symptomatology. A cross-sectional perinatal sample (N = 344) completed questionnaires of dysfunctional attitudes (both general and specific to motherhood), metacognitions, and sociodemographic factors including age, ethnicity, education, marital status, parity and previous history of mental health problems. Correlational analyses indicated that dysfunctional attitudes (both general and specific to motherhood), as well as metacognitions were intercorrelated and all were associated with perinatal depressive symptomatology. Controlling for sociodemographic factors, hierarchical regression analysis showed that general dysfunctional attitudes were weakly associated with perinatal depression. Moreover, maladaptive attitudes specific to motherhood and negative beliefs about the uncontrollability and danger of worry were independently associated with perinatal depressive symptomatology, with the latter variable having the strongest association with the outcome variable. Path analyses demonstrated that negative beliefs about the uncontrollability and danger of worry partially mediated the relationship between maladaptive attitudes specific to motherhood and perinatal depressive symptomatology. The results support the metacognitive conceptualisation of psychopathology which places importance on metacognitions in the maintenance of depression.

Transcultural, transdiagnostic, and concurrent validity of a revised metacognitions about symptoms control scale

Anxiety and depression add to the burden of chronic fatigue syndrome (CFS), fibromyalgia (FM), and type 1 diabetes mellitus (T1DM). Metacognitions play a role in this distress. The metacognitions about symptoms control scale (MaSCS) measure metacognitive beliefs regarding symptoms but have weaknesses. The current study created a revised MaSCS (MaSCS-R) in English, German, and Arabic versions using CFS, FM, and T1DM samples and examined the transcultural, transdiagnostic, and concurrent validity of metacognitions about symptom control. This study used data from 563 participants clinically diagnosed with CFS (n = 124; English), FM (n = 348; German), or T1DM (n = 91; Lebanese). CFS and FM data had been used in earlier published studies but were subjected to new analyses. CFS data were used to create the English version of the MaSCS-R and FM and T1DM data for German and Arabic versions. Metacognitions about worry, anxiety, depression, and symptom severity were measured. The three MaSCS-R versions, consisting of two factors (each with four items), had adequate psychometric properties, possessing configural and metric invariance. Metacognitive factors were associated with distress and symptom severity in all three samples. Metacognitions about symptom control have transcultural, transdiagnostic, and concurrent validity.

Qualitative Analysis of Emotional Distress in Cardiac Patients From the Perspectives of Cognitive Behavioral and Metacognitive Theories: Why Might Cognitive Behavioral Therapy Have Limited Benefit, and Might Metacognitive Therapy Be More Effective?

Introduction: Cognitive behavioral therapy (CBT) alleviates emotional distress in mental health settings, but has only modest effects in cardiac patients. Metacognitive therapy (MCT) also alleviates depression and anxiety in mental health settings and is in its initial stages of evaluation for cardiac patients. Aim: Our objective is to compare how CBT and MCT models conceptualize cardiac patients' distress, and to explore why CBT has had limited benefit for cardiac patients and whether MCT has the potential to be more efficacious. Method: Forty-nine cardiac rehabilitation patients, who screened positively for anxiety and/or depression, provided semi-structured interviews. We analyzed transcripts qualitatively to explore the "fit" of patients' accounts of their distress with the main elements of cognitive behavioral and metacognitive theories. Four illustrative cases, representative of the diverse presentations in the broader sample, were analyzed in detail and are presented here. Results: Conceptualizing patients' distress from the perspective of CBT involved applying many distinct categories to describe specific details of patients' talk, particularly the diversity of their concerns and the multiple types of cognitive distortion. It also required distinction between realistic and unrealistic thoughts, which was difficult when thoughts were associated with the risk or consequences of cardiac events. From the perspective of MCT a single category-perseverative negative thinking-was sufficient to understand all this talk, regardless of whether it indicated realistic or unrealistic thoughts, and could also be applied to some talk that did not seem relevant from a CBT perspective. Discussion: Conceptualizing distress from the perspective of CBT presents multiple, diverse therapeutic targets, not all of which a time-limited therapy would be able to address. Given the difficulty of identifying them as unrealistic or not, thoughts about disease, death or disability may not be amenable to classic CBT techniques such as reality testing. MCT proved more parsimonious and, because it did not distinguish between realistic and unrealistic thoughts, might prove a better fit to emotional distress in cardiac patients.

Tolerance of uncertainty: A systematic review of health and healthcare-related outcomes

BACKGROUND

Uncertainty tolerance (UT) is thought to be a characteristic of individuals that influences various outcomes related to health, healthcare, and healthcare education. We undertook a systematic literature review to evaluate the state of the evidence on UT and its relationship to these outcomes.

METHODS

We conducted electronic and bibliographic searches to identify relevant studies examining associations between UT and health, healthcare, or healthcare education outcomes. We used standardized tools to assess methodological quality and analyzed the major findings of existing studies, which we organized and classified by theme.

RESULTS

Searches yielded 542 potentially relevant articles, of which 67 met inclusion criteria. Existing studies were heterogeneous in focus, setting, and measurement approach, were largely cross-sectional in design, and overall methodological quality was low. UT was associated with various trainee-centered, provider-centered, and patient-centered outcomes which were cognitive, emotional, and behavioral in nature. UT was most consistently associated with emotional well-being.

CONCLUSIONS

Uncertainty tolerance is associated with several important trainee-, provider-, and patient-centered outcomes in healthcare and healthcare education. However, low methodological quality, study design limitations, and heterogeneity in the measurement of UT limit strong inferences about its effects, and addressing these problems is a critical need for future research.

The contribution of illness perceptions and metacognitive beliefs to anxiety and depression in adults with diabetes

AIMS

Anxiety and depression are highly prevalent in people with diabetes (PwD). The most widely used psychological model to explain anxiety and depression in PwD is the Common-Sense Model, which gives a central role to illness perceptions. The Self-Regulatory Executive Function (S-REF) model proposes metacognitive beliefs are key to understanding the development and maintenance of emotional disorders. To test the potential utility of the S-REF model in PwD, the study explored if metacognitive beliefs explained additional variance in anxiety and depression after controlling for demographic and illness perceptions.

METHODS

614 adults with either Type 1 (n = 335) or Type 2 (n = 279) diabetes participated in a cross sectional online survey. All participants completed questionnaires on anxiety, depression, illness perceptions and metacognitive beliefs.

RESULTS

Regression analyses showed that metacognitive beliefs were associated with anxiety and depression in PwD and explained additional variance in both anxiety and depression after controlling for demographics and illness perceptions.

CONCLUSIONS

This is the first study to demonstrate that metacognitive beliefs are associated with anxiety and depression in PwD. The clinical implications of the study are illustrated.

Somatization in Parkinson's Disease: A systematic review

The current systematic review study is aimed at critically analyzing from a clinimetric viewpoint the clinical consequence of somatization in Parkinson's Disease (PD). By focusing on the International Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive electronic literature research strategy on ISI Web-of-Science, PsychINFO, PubMed, EBSCO, ScienceDirect, MEDLINE, Scopus, and Google Scholar databases. Out of 2.926 initial records, only a total of 9 studies were identified as clearly relevant and analyzed in this systematic review. The prevalence of somatization in PD has been found to range between 7.0% and 66.7%, with somatoform disorders acting as clinical factor significantly contributing to predict a progressive cognitive impairment. We highlighted that somatization is a highly prevalent comorbidity affecting PD. However, the clinical consequence of such psychiatric symptom should be further evaluated by replacing the clinically inadequate diagnostic label of psychogenic parkinsonism with the psychosomatic concept of persistent somatization as conceived by the Diagnostic Criteria for Psychosomatic Research (DCPR).

Metacognitive Therapy for Emotional Distress in Adult Cancer Survivors: A Case Series

Many adult cancer survivors experience persistent emotional distress after completing cancer treatment. The aim of this study was to test the potential of a brief transdiagnostic psychological intervention—metacognitive therapy (MCT)—in reducing emotional distress in adult cancer survivors. A non-concurrent multiple baseline design with 3- and 6-months follow-up was used to evaluate the effects of MCT in four patients consecutively referred to a psycho-oncology service. Each patient received six 1-h sessions of MCT. Anxiety, depression, worry/rumination, fear of cancer recurrence and metacognitive beliefs were assessed using self-report questionnaires. MCT was associated with clinically significant reductions in anxiety, depression, fear of cancer recurrence, worry/rumination and metacognitive beliefs at the end of treatment, and gains were maintained in all patients to 3-months follow-up and in three out of four patients to 6-months follow-up. MCT is a promising brief transdiagnostic approach to psychological morbidity in adult survivors of cancer. Larger scale controlled trials are now required.

Human behavioral assessments in current research of Parkinson's disease

Parkinson's disease (PD) is traditionally classified as a movement disorder because patients mainly complain about motor symptoms. Recently, non-motor symptoms of PD have been recognized by clinicians and scientists as early signs of PD, and they are detrimental factors in the quality of life in advanced PD patients. It is crucial to comprehensively understand the essence of behavioral assessments, from the simplest measurement of certain symptoms to complex neuropsychological tasks. We have recently reviewed behavioral assessments in PD research with animal models (Asakawa et al., 2016). As a companion volume, this article will systematically review the behavioral assessments of motor and non-motor PD symptoms of human patients in current research. The major aims of this article are: (1) promoting a comparative understanding of various behavioral assessments in terms of the principle and measuring indexes; (2) addressing the major strengths and weaknesses of these behavioral assessments for a better selection of tasks/tests in order to avoid biased conclusions due to inappropriate assessments; and (3) presenting new concepts regarding the development of wearable devices and mobile internet in future assessments. In conclusion we emphasize the importance of improving the assessments for non-motor symptoms because of their complex and unique mechanisms in human PD brains.

The association between metacognitions and the impact of Fibromyalgia in a German sample

OBJECTIVES

Fibromyalgia is a chronic condition of unknown aetiology, characterised by widespread pain, sleep disturbances, and fatigue. In this paper we examined the relationship metacognitions and the impact of Fibromyalgia in a German sample, detailing the translation and validation of a self-report metacognitive instrument.

METHODS

The Metacognitions about Symptoms Control Scale (MaSCS) was translated into German using the back-forward translation process. A total of 348 patients (316 female and 26 male) with Fibromyalgia contributed data to the study to test the structure and psychometric properties of the MaSCS.

RESULTS

Confirmatory factor analyses, informed by modification indices, resulted in a 16-item scale consisting of two factors pertaining to positive and negative metacognitions about symptoms control. Further analyses revealed that both factors had good internal consistency. Correlation analyses established convergent validity, indicating that both factors were significantly associated with: (1) established positive and negative metacognitions scales; and (2) with symptoms severity in Fibromyalgia. Regression analyses revealed that positive metacognitions about symptoms control significantly predicted impairment in physical functioning while negative metacognitions about symptoms control significantly predicted the overall Fibromyalgia impact value, when controlling for stress, anxiety, and depression and a general metacognitions.

CONCLUSION

The findings support the potential relevance of metacognitions, and utility of the German version of MaSCS, in examining the role of metacognitions in Fibromyalgia and other chronic health conditions.

Clinical utility of the Metacognitions Questionnaire 30 in people with epilepsy

OBJECTIVE

The Metacognitions Questionnaire 30 (MCQ-30) has been widely used to assess metacognitive beliefs and processes linked to emotional disorders. The aim of the present study was to test the utility of the MCQ-30 in assessing metacognitions in people with epilepsy.

METHODS

Three hundred forty-nine people with epilepsy completed the MCQ-30 and self-report measures of anxiety and depression at two time points, 12 months apart. Factor analyses and structural equation modeling were used to test the factor structure, internal consistency, and convergent validity of the MCQ-30.

RESULTS

Confirmatory and exploratory factor analyses supported the original five-factor structure and demonstrated that each factor had good to excellent levels of internal consistency.

CONCLUSION

The MCQ-30 is a robust measure of metacognitive beliefs and processes and has clinical utility in PWE.

Rumination and behavioural factors in Parkinson's disease depression

OBJECTIVE

Parkinson's disease is associated with high rates of depression. There is growing interest in non-pharmacological management including psychological approaches such as Cognitive Behaviour Therapy. To date, little research has investigated whether processes that underpin cognitive models of depression, on which such treatment is based, apply in patients with Parkinson's disease. The study aimed to investigate the contribution of core psychological factors to the presence and degree of depressive symptoms.

METHODS

104 participants completed questionnaires measuring mood, motor disability and core psychological variables, including maladaptive assumptions, rumination, cognitive-behavioural avoidance, illness representations and cognitive-behavioural responses to symptoms.

RESULTS

Regression analyses revealed that a small number of psychological factors accounted for the majority of depression variance, over and above that explained by overall disability. Participants reporting high levels of rumination, avoidance and symptom focusing experienced more severe depressive symptoms. In contrast, pervasive negative dysfunctional beliefs did not independently contribute to depression variance.

CONCLUSION

Specific cognitive (rumination and symptom focusing) and behavioural (avoidance) processes may be key psychological markers of depression in Parkinson's disease and therefore offer important targets for tailored psychological interventions.

Thinking about motor fluctuations: An examination of metacognitions in Parkinson's disease

OBJECTIVE

Motor fluctuations (characterised by a sudden increase in symptom intensity, referred to as an 'off-period') are common side effects after treatment of Parkinson's disease (PD) with dopaminergic medication. A proportion of these people find motor fluctuations highly distressing. This study aimed to identify metacognitions associated with cognitive and attentional responses to these experiences.

METHODS

Ten individuals with PD who experience motor fluctuations were interviewed for this study using an adapted metacognitive profiling schedule. Participants were asked about their metacognitions, and the cognitive processes and attentional strategies activated in response to a distressing off-period.

RESULTS

Metacognitions identified were more often related to conceptual thinking about symptoms rather than symptom focus and data suggested trends for increased depressive symptoms among individuals with stronger metacognitive beliefs.

CONCLUSION

Metacognitions may play a role in determining or maintaining off-period distress in PD.
