Show moreIntroduction: No studies have reported mental health symptom comparisons prior to and during COVID-19 in vulnerable medical populations.Objective: To compare anxiety and depression symptoms among people with a pre-existing medical condition and factors associated with changes.Methods: Pre-COVID-19 Scleroderma Patient-centered Intervention Network Cohort data were linked to COVID-19 data from April 2020. Multiple linear and logistic regression were used to assess factors associated with continuous change and >= 1 minimal clinically important difference (MCID) change for anxiety (PROMIS Anxiety 4a v1.0; MCID = 4.0) and depression (Patient Health Questionnaire-8; MCID = 3.0) symptoms, controlling for pre-COVID-19 levels.Results: Mean anxiety symptoms increased 4.9 points (95% confidence interval [CI] 4.0 to 5.7). Depression symptom change was negligible (0.3 points; 95% CI-0.7 to 0.2). Compared to France (N = 159), adjusted anxiety symptom change scores were significantly higher in the United Kingdom (N = 50; 3.3 points, 95% CI 0.9 to 5.6), United States (N = 128; 2.5 points, 95% CI 0.7 to 4.2), and Canada (N = 98; 1.9 points, 95% CI 0.1 to 3.8). Odds of >= 1 MCID increase were 2.6 for the United Kingdom (95% CI 1.2 to 5.7) but not significant for the United States (1.6, 95% CI 0.9 to 2.9) or Canada (1.4, 95% CI 0.7 to 2.5). Older age and adequate financial resources were associated with less continuous anxiety increase. Employment and shorter time since diagnosis were associated with lower odds of a >= 1 MCID increase.Conclusions: Anxiety symptoms, but not depression symptoms, increased dramatically during COVID-19 among people with a pre-existing medical condition.

Show moreAnxiety disorders are characterized by difficulty distinguishing safe contexts from previous or imagined threats. Conditioned fears spread beyond what is reasonable or adaptive, leading to broad and interfering anxieties when people overgeneralize their fears. Difficulties with mnemonic discrimination, a component process of memory supporting the integration of old and new experiences, may foster overgeneralization and increase risk for anxiety disorders. Individuals along a spectrum of anxiety severity (n = 117) completed a differential fear conditioning paradigm and the computerized Mnemonic Similarity Task. The task measures mnemonic discrimination by requiring individuals to differentiate between highly similar old and new entities. We predicted that low mnemonic discrimination would be associated with overgeneralization, i.e., flatter slopes of change in response to stimuli increasingly dissimilar to the conditioned stimulus. Conditional growth models showed that as expected, participants with the highest mnemonic discrimination scores also exhibited the steepest declines in fear ratings as stimuli increasingly differed from the conditioned stimulus. Results were unchanged after adjusting for recognition memory, self-reported anxiety, and clinical diagnoses and symptoms. Results support the hypothesis that memory interference (i.e., low mnemonic discrimination) could increase vulnerability for overgeneralization. Findings justify additional exploration of mnemonic discrimination and its role in anxious psychopathology. Show less

Show moreIn this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models. More specifically, we have looked at the role of the ECS in regulating locomotion and anxiety, and its interaction with the hypothalamic-pituitary-interrenal (HPI) axis, or stress axis. This study has provided us with an interesting animal model which allows for pharmacological screening of Cnr1 agonists, and their involvement in the CNS, as shown by a change in locomotion, anxiety-like behavior and HPI axis activity. The zebrafish larval model can be used as a complementary model to the existing rodent animal models, to study the ECS. The zebrafish larval model brings several interesting features, such as optical transparency and possibilities for high-throughput screening. Furthermore, a complete ECS is present, there is lack of endogenous activity, allowing for exogenous compound screening, and zebrafish data is generally in line with rodent literature. Since the ECS is involved in many diseases, more research of this system may result in the discovery of novel drugs and drug targets. Show less

Show moreBackground Comorbidity between depressive and anxiety disorders is common. A hypothesis of the network perspective on psychopathology is that comorbidity arises due to the interplay of symptoms shared by both disorders, with overlapping symptoms acting as so-calledbridges, funneling symptom activation between symptom clusters of each disorder. This study investigated this hypothesis by testing whether (i) twooverlappingmental states "worrying" and "feeling irritated" functioned as bridges in dynamic mental state networks of individuals with both depression and anxiety as compared to individuals with either disorder alone, and (ii) overlapping or non-overlapping mental states functioned as stronger bridges. Methods Data come from the Netherlands Study of Depression and Anxiety (NESDA). A total of 143 participants met criteria for comorbid depression and anxiety (65%), 40 participants for depression-only (18.2%), and 37 for anxiety-only (16.8%) during any NESDA wave. Participants completed momentary assessments of symptoms (i.e., mental states) of depression and anxiety, five times a day, for 2 weeks (14,185 assessments). First, dynamics between mental states were modeled with a multilevel vector autoregressive model, using Bayesian estimation. Summed average lagged indirect effects through the hypothesized bridge mental states were compared between groups. Second, we evaluated the role of all mental states as potential bridge mental states. Results While the summed indirect effect for the bridge mental state "worrying" was larger in the comorbid group compared to the single disorder groups, differences between groups were not statistically significant. The difference between groups became more pronounced when only examining individuals with recent diagnoses (< 6 months). However, the credible intervals of the difference scores remained wide. In the second analysis, a non-overlapping item ("feeling down") acted as the strongest bridge mental state in both the comorbid and anxiety-only groups. Conclusions This study empirically examined a prominent network-approach hypothesis for the first time using longitudinal data. No support was found for overlapping mental states "worrying" and "feeling irritable" functioning as bridge mental states in individuals vulnerable for comorbid depression and anxiety. Potentially, bridge mental state activity can only be observed during acute symptomatology. If so, these may present as interesting targets in treatment, but not prevention. This requires further investigation. Show less

Show moreObjective: Contagious disease outbreaks and related restrictions can lead to negative psychological outcomes, particularly in vulnerable populations at risk due to pre-existing medical conditions. No randomised controlled trials (RCTs) have tested interventions to reduce mental health consequences of contagious disease outbreaks. The primary objective of the Scleroderma Patient-centered Intervention Network COVID-19 Home-isolation Activities Together (SPIN-CHAT) Trial is to evaluate the effect of a videoconference-based program on symptoms of anxiety. Secondary objectives include evaluating effects on symptoms of depression, stress, loneliness, boredom, physical activity, and social interaction.Methods: The SPIN-CHAT Trial is a pragmatic RCT that will be conducted using the SPIN-COVID-19 Cohort, a sub-cohort of the SPIN Cohort. Eligible participants will be SPIN-COVID-19 Cohort participants without a positive COVID-19 test, with at least mild anxiety (PROMIS Anxiety 4a v1.0 T-score >= 55), not working from home, and not receiving current counselling or psychotherapy. We will randomly assign 162 participants to intervention groups of 7 to 10 participants each or waitlist control. We will use a partially nested RCT design to reflect dependence between individuals in training groups but not in the waitlist control. The SPIN-CHAT Program includes activity engagement, education on strategies to support mental health, and mutual participant support. Intervention participants will receive the 4-week (3 sessions per week) SPIN-CHAT Program via video-conference. The primary outcome is PROMIS Anxiety 4a score immediately post-intervention.Ethics and dissemination: The SPIN-CHAT Trial will test whether a brief videoconference-based intervention will improve mental health outcomes among at-risk individuals during contagious disease outbreak.

Show moreObjective: Depression and anxiety often coexist in patients with end -stage -kidney disease. Recently, studies showed that a composite ?general distress score ? which combines depression and anxiety symptoms provides a good fit in dialysis and oncology patients. We aim to investigate if the three most frequently used self -report questionnaires to measure depression and anxiety in dialysis patients are sufficiently unidimensional to warrant the use of such a general distress score in two cohorts of dialysis patients. Methods: This study includes two prospective observational cohorts of dialysis patients (total n = 749) which measured depression and anxiety using Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Hospital Anxiety and Depression Scale (HADS). Confirmatory factor analyses was used to investigate both a strictly unidimensional model and a multidimensional bifactor model that includes a general distress, depression and anxiety factor. The comparative fit index (CFI) and The Root Mean Square Error of Approximation (RMSEA) were used as model fit indices. Results: Factor analysis did not show a good fit for a strictly unidimensional general distress factor for both the BDI/BAI and HADS (CFI 0.690 and 0.699, RMSEA 0.079 and 0.125 respectively). The multidimensional model performed better with a moderate fit for the BDI/BAI and HADS (CFI 0.873 and 0.839, RMSEA 0.052 and 0.102). Conclusions: This data shows that the BDI/BAI and HADS are insufficiently unidimensional to warrant the use of a general distress score in dialysis patients without also investigating anxiety and depression separately. Future research is needed whether the use of a general distress score might be beneficial to identify patients in need of additional (psychological) support. Show less

Show moreBackground and objectives: Emotion can be seen as the organizing process that coordinates response systems to deal effectively with challenges and opportunities. Synchronous change in subjective and physiological reactivity is regarded as an indication of this organizing process. Synchrony is expected to increase with the intensity of emotional stimuli. Conversely, adaptive emotional functioning could be indicated by progressive synchrony upon increasing demands, and the magnitude of synchrony could be an indication of progress during therapy.Methods: We examined whether synchronous change in subjective and physiological reactivity over repeated exposures increased from watching a flight video through simulated flight to actual flight, and whether the magnitude of synchronous change predicted favourable short- and long-term treatment outcome within a group of 77 aviophobic participants during CBT.Results: Results did not show a relationship between the intensity of the phobic stimuli and the magnitude of synchronous change in subjective and physiological reactivity. Moreover, synchronous change across both response systems did not predict treatment outcome.Limitations: By design this study had no control group. Additional treatment or life events between end of treatment and 3-year follow-up were not assessed.Conclusion: The results provide only weak support for the functionalistic view that successful treatment of anxiety disorders is indicated by synchronous change in reactivity across emotional response systems. The relationship between these systems is likely to be affected by many intervening variables including higher order cognitive processes. Show less

Show moreObjective: To describe the prevalence and prognostic factors of symptoms of anxiety and depression and posttraumatic stress symptoms (PTSS) after injury in the clinical trauma population.Design: Multicenter, prospective, observational cohort study.Setting: Ten hospitals in Noord-Brabant, The Netherlands.Participants: Four thousand two hundred thirty-nine adult patients (N=4239) admitted due to injury between August 2015 and December 2016.Interventions: Patients were asked to complete a questionnaire at 1 week and at 1, 3, 6, and 12 months after injury.Main Outcome Measures: The Hospital Anxiety and Depression Scale was used to assess anxiety and depressive symptoms and the Impact of Event Scale was used to assess PTSS.Results: The prevalence of symptoms of anxiety and depression decreased from 10% and 12%, respectively, at 1 week after injury to 7% and 7% at 12 months after injury. Acute traumatic stress symptoms were present in 13% at 1 week and PTSS was prevalent in 10% of the participants at 12 months after injury. Strong prognostic factors for poor psychological outcome in multivariable logistic mixed models were preinjury frailty, psychological complaints and nonworking status preinjury, female sex, low educational level, and accident category (ie, traffic accident, work-related accident, or accidents at home compared to sport injuries).Conclusions: Psychological distress is a common health problem during the first year after injury. Important prognostic factors for psychological distress include psychological complaints before injury and frailty. Early recognition of psychological problems after injury could facilitate discussion between caregivers and patients and improve recovery.

Show moreThis thesis describes the relation of fear of childbirth (FOC), measured pre- and postpartum, with the preferred and actual place and mode of giving birth and with the use of pharmacological pain relief during labour. The studies were embedded in the Dutch obstetric system, where midwives have an independent profession and where home birth is an accepted option for women with a low-risk pregnancy. The general finding, consistent across all studies in this thesis, is that the level of FOC in pregnancy was strongly related to, and predictive of the level of postpartum FOC. Furthermore, women with severe FOC during pregnancy were prone to preferring a hospital birth, having pharmacological pain relief during labour and requesting an elective Caesarean Section. Congruence between one’s own preference (of place or mode of giving birth) and the actual delivery situation was not related to the degree of postpartum FOC. Instead, predictors for high postpartum FOC were: being referred from midwifery-led care to obstetrician-led care, emergency Caesarean Section, and a poor condition of the new-born. For guiding women with severe FOC through pregnancy and childbirth, a close collaboration between the obstetric caregiver and a psychotherapist is advised. Show less

Show morePurpose Adherence to the Mediterranean diet has been associated with fewer depressive symptoms, however, it is unknown whether this is attributed to some or to all components. We examined the association between the individual food groups of the Mediterranean Diet Score (MDS), in isolation and in combination, with depression and anxiety (symptom severity and diagnosis). Methods Data from 1634 adults were available from the Netherlands Study of Depression and Anxiety. Eleven energy-adjusted food groups were created from a 238-item food frequency questionnaire. In regression analysis, these were associated in isolation and combination with (1) depressive and anxiety disorders (established with the Composite International Diagnostic Interview) (current disorder n = 414), and (2) depression and anxiety severity [measured with the Inventory of Depressive Symptomatology (IDS), the Beck Anxiety Inventory (BAI) and the Fear Questionnaire (FEAR)]. Results Overall, the MDS score shows the strongest relationships with depression/anxiety [Diagnosis: odds ratio (OR) 0.77 per SD, 95% confidence interval (95% CI) 0.66-0.90, IDS: standardised betas (beta) - 0.13, 95% CI - 0.18, - 0.08] and anxiety (BAI: beta - 0.11, 95% CI - 0.16, - 0.06, FEAR: beta - 0.08, 95% CI - 0.13, - 0.03). Greater consumption of non-refined grains and vegetables was associated with lower depression and anxiety severity, whilst being a non-drinker was associated with higher symptom severity. Higher fruit and vegetable intake was associated with lower fear severity. Non-refined grain consumption was associated with lower odds and being a non-drinker with greater odds of current depression/anxiety disorders compared to healthy controls, these associations persisted after adjustment for other food groups (OR 0.82 per SD, 95% CI 0.71-0.96, OR 1.26 per SD 95% CI 1.08-1.46). Conclusion We can conclude that non-refined grains, vegetables and alcohol intake appeared to be the driving variables for the associated the total MDS score and depression/anxiety. However, the combined effect of the whole diet remains important for mental health. It should be explored whether an increase consumption of non-refined grains and vegetables may help to prevent or reduce depression and anxiety. Show less

Show moreArt therapy is an often provided but little studied treatment option in mental health care.The effectiveness of art therapy in the treatment of anxiety was studied and its working mechanisms were explored. Outcomes of a randomised controlled trial (n=59) showed preliminary evidence of the effectiveness of art therapy. The treatment, consisting of three months of anthroposophic art therapy, showed major reduction of anxiety symptom severity in women, compared to a wait list condition. The therapy also improved quality of life and various aspects of self-regulation: higher HRV at rest (which may indicate an overall lower stress level), improvements in emotion regulation and improvements in daily executive functioning.The second part of this PhD research focused on case report methodology and the development of tools for research within this field, with and for therapists in clinical practice, and for education. A publication guideline for case reports was developed and positively evaluated in practice. An exemplary case report of a female client with anxiety was provided.The outcomes of this research support the indication of art therapy in the treatment of anxiety and justify further studying of the effectiveness and mechanisms of art therapy.
