The psychometric properties of an e-headache diary in migraine.

ObjectiveTo evaluate the psychometric characteristics of a previously validated electronic headache diary with automated algorithm for the purpose of identifying migraine days.MethodsThe psychometric properties of 13 variables in this e-diary were analyzed using item response theory (IRT) in migraine patients from the Leiden Headache Center. The included items were headache presence, duration, unilaterality, severity, pulsating, aggravation by physical activity, visual aura, aura duration, nausea, vomiting, photophobia or phonophobia and triptan usage.

Association between device-based measured physical activity timing and depression risk: a prospective cohort study of UK Biobank participants.

Introduction: Physical activity (PA) decreases the risk of mental diseases. Although PA timing has been hypothesised to affect mental health outcomes, no large-scale epidemiological cohort studies have been performed. We investigated the association between PA timing and incident depression in the general population.

Dynamic time warping network analysis of posttraumatic stress symptoms in Japanese first responders.

A more inclusive approach for addressing the diverse spectrum of mental health experiences is needed. Network theory frames psychopathological complaints as complex dynamic systems, that can be modelled in a network of mutually interacting symptoms. These networks may provide important markers of symptom improvement or exacerbation, and inform strategies for early intervention and treatment.

Temporal dynamics of perceived self-reliance and psychiatric symptoms in older adults: applying dynamic time warping to longitudinal cohort data.

Objectives: Contemporary public health and care policies expect that promoting self-reliance can help older adults prevent or recover from morbidity, including psychiatric disorders. We sought to clarify the role of self-reliance dynamics in developing and recovering from psychiatric symptoms throughout the aging process.

Method: We used dynamic time warping to analyze the temporal ordering of within-person changes in five self-reliance indicators (three self-efficacy dimensions, mastery, self-esteem) and psychiatric symptoms in  = 1968 participants aged 55+ in the Longitudinal Aging Study Amsterdam, measured up to ten times across up to 30 years.

Dynamic time warping to model daily life stress reactivity in a clinical and non-clinical sample - An ecological momentary assessment study.

Background: Dysregulated stress reactivity has been closely linked to psychopathology. However, most studies have applied cross-sectional lab-based methodologies rather than longitudinal designs, like ecological momentary assessment (EMA). EMA provides dynamic, time-sensitive data that require advanced analytical approaches.

Hair Cortisone Levels and the Metabolic Syndrome: Stronger Links in Younger Compared to Older Adults.

Background: The striking link between Cushing's syndrome, the metabolic syndrome (MetS), and cardiovascular disease suggests that long-term exposure to high glucocorticoid levels catalyzes cardiometabolic deterioration. However, the relation of subtle variations in long-term glucocorticoid levels with MetS remains poorly understood. Specifically, little is known about potential moderating roles of age, sex and mental health status in this association.

Six-year trajectories of core depressive symptoms and insomnia symptoms in depressed older adults: a NESDO study.

Objectives: This study aimed to identify trajectories of core depressive symptoms and insomnia symptoms in depressed older adults, their prevalence and association, and predictors of unfavorable trajectories.

Method: We examined 6-year follow-up data of 329 depressed older adults from the Netherlands Study of Depression in Older persons. Core depressive symptoms and insomnia symptoms were assessed with the Inventory of Depressive Symptomatology.

Introduction to the "Japanese and Western approaches to psychotrauma" symposium.

Understandings of psychotrauma have changed throughout medical history, shaped by cultural and social factors. Reviewing transcultural perspectives of psychotrauma helps understand its complexities and contextual impacts. This paper summarizes the Japan-Netherlands symposium on psychotrauma held on March 1, 2024.

Unveiling Transitions in Disease States: Study of Depressive and Anxiety Symptom Networks over Time.

Background: Major depressive disorder (MDD) and anxiety disorders (AD) have high degrees of comorbidity and show great overlap in symptoms. The analysis of covarying depressive- and anxiety symptoms in longitudinal, sparse data panels has received limited attention. Dynamic time warping (DTW) analysis may help to provide new insights into symptom network properties based on diagnostic- and disease-state stability criteria.

The Metabolomic Signature of Childhood Trauma.

Background: Although childhood trauma is an important risk factor for various diseases, the underlying biological mechanisms remain insufficiently understood. To deepen this understanding, we investigated the wide-spectrum metabolomic signature of childhood trauma exposure in a large adult cohort.

Methods: Baseline and 6-year follow-up data from NESDA (Netherlands Study of Depression and Anxiety) were used (N = 2902, N = 4800).

Community Norms for the Symptom Questionnaire (SQ-48): Normalised T-Scores and Percentile Rank Order Scores.

Use of standardised scores, such as T-scores and percentile rank order scores, enhances measurement-based care. They facilitate communication between therapists and clients about test results, particularly for multidimensional measures such as the Symptoms Questionnaire (SQ-48). By transforming raw scores into a common metric, clinicians can more easily interpret and discuss patient profiles of scores on the various scales of the measure.

Temporal Dynamics of Depressive Symptoms, Apathy, Daily Activities, and Cognitive Decline in Older People From the General Population: A Network Analysis.

Background: The prevalence of depressive symptoms, apathy, and cognitive decline increases with age. Understanding the temporal dynamics of these symptoms could provide valuable insights into the early stages of cognitive decline, allowing for more timely and effective treatment and management.

Methods: Participants from the Prevention of Dementia by Intensive Vascular Care (preDIVA) trial cohort with baseline and ≥3 follow-up measurements were included, with a median of 7.

Immune-neuroendocrine crosstalk in mood and psychotic disorders: A meta-analysis and systematic review.

Background: Bidirectional interactions between immune and neuroendocrine mechanisms are involved in mood and psychotic disorders, although individual studies report inconsistent and even contradictory findings on the nature of this crosstalk. Our objective was to perform an up to date systematic review and meta-analysis of the association between hypothalamic-pituitary-adrenal (HPA) axis and immune system functioning in mood and psychotic disorders.

Methods: We searched the Pubmed, Web of Science and Embase databases for studies reporting correlations between one or more HPA- and immune markers (IM) in patients with mood or psychotic disorders.

Adopting a complex systems approach to functional ageing: bridging the gap between gerontological theory and empirical research.

Functional ageing, related to but distinct from biological and environmental systems, is defined as the changes in physical, psychological, cognitive, and social functioning, as well as behavioural factors of individuals as they age. In this Personal View, we propose that a complex systems perspective to functional ageing can show how outcomes such as quality of life and longevity, and success in prevention and treatment, emerge from dynamic interactions among these domains, rather than from single causes. We support this view in three ways.

Symptoms of Posttraumatic Stress Disorder Among Japanese Peacekeepers Deployed in South Sudan.

Importance: Peacekeepers in United Nations missions experience potentially traumatic events, resulting in increased risk for posttraumatic stress disorder (PTSD). Understanding the course and risk factors of PTSD symptom severity is crucial to ensure personnel safety.

Objective: To investigate the incidence of PTSD, symptom severity trajectories, and potential risk factors associated with adverse trajectories among Japanese peacekeepers deployed in South Sudan.

Borderline personality features in relationship to childhood trauma in unipolar depressive and bipolar disorders.

Background: Childhood trauma, including emotional neglect, emotional abuse, physical abuse, and sexual abuse, may contribute to borderline personality features like affective instability, identity problems, negative relationships, and self-harm. This study aims to explore how different types of childhood trauma affect these features in bipolar versus unipolar depressive disorders.

Methods: We included 839 participants of the Netherlands Study of Depression and Anxiety (NESDA) with a lifetime diagnosis of major depressive disorder single episode (MDDS; N = 443), recurrent major depressive disorder (MDD-R; N = 331), or bipolar disorder (BD; N = 65).

Network dynamics of self-compassion, anxiety, and depression during eating disorder therapy.

Background: Recovery processes during residential treatment for eating disorders, especially in patients with a history of maltreatment, are insufficiently understood. This study aimed to explore the temporal relationships among comorbid factors, including depression, anxiety, and self-compassion, with the influence of childhood maltreatment.

Method: Using Dynamic Time Warp (DTW), weekly scores from the Symptom Checklist-5, Eating Disorder Examination, and Self-Compassion Scale were analysed over 12 weeks.

Temporal dynamics of depressive symptoms and cognitive decline in the oldest old: dynamic time warp analysis of the Leiden 85-plus study.

Background: The prevalence of depressive symptoms and cognitive decline increases with age. We investigated their temporal dynamics in individuals aged 85 and older across a 5-year follow-up period.

Methods: Participants were selected from the Leiden 85-plus study and were eligible if at least three follow-up measurements were available (325 of 599 participants).

The clinical effectiveness of a self-management intervention for patients with persistent depressive disorder and their partners/caregivers: results from a multicenter, pragmatic randomized controlled trial.

Background: Persistent depressive disorder (PDD) is prevalent and debilitating. For patients with PDD, psychiatric rehabilitation using self-management interventions is advised as the next therapeutic step after multiple unsuccessful treatment attempts. The "Patient and Partner Education Program for All Chronic Diseases" (PPEP4All) is a brief, structured self-management program that focuses on functional recovery for patients and their partners/caregivers.
