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.
The behavioral restrictions disrupting daily life during the COVID-19 pandemic have profoundly impacted well-being, and health behaviors have been advocated to prevent decline. To understand how processes related to fluctuation in well-being unfold within individuals, analyses on the within-person level are required. In this preregistered intensive longitudinal study, 1,709 individuals from the Norwegian adult population provided data daily over 40 consecutive days during the pandemic.

We aimed to assess the prevalence of physical symptoms in relation to acute illness severity up to more than 2-years after diagnosis of COVID-19.
Methods: This multinational study included 64,880 adult participants from Iceland, Sweden, Denmark, and Norway with self-reported data on COVID-19 and physical symptoms from April 2020 to August 2022.
Objective: Posttraumatic stress disorder (PTSD) remains a growing public health challenge across the globe and is associated with negative and persistent long-term consequences. The last decades of research have identified different mechanisms associated with the development and persistence of PTSD, including maladaptive coping strategies, cognitive and experiential avoidance, and positive and negative metacognitions. Despite these advances, little is known about how these different processes interact with specific PTSD symptoms, and how they influence each other over time at the within-person level.

Longitudinal within-person analyses of therapy processes are scarce. Our aim was to investigate central change processes in therapy in a transdiagnostic sample, considering the influence of childhood maltreatment.

However, the specific psychopathological processes related to within-person variation and maintenance of anxiety symptomatology and parental distress components in the parental population have been largely unexplored in the literature.
Methods: In this preregistered intensive longitudinal study, a multilevel dynamic network was used to model within-person interactions between anxiety symptomatology, psychopathological processes, parental distress, and protective lifestyle components in a sample of 495 parents-each responding to daily assessments over a 40-day period.
Background: A large proportion of patients with eating disorders (ED) report experiences of childhood trauma. Latent trajectory analysis in ED samples reveals the complexities in course and outcome and can explore the long-term impact of adverse experiences in childhood.
Method: A total of 84 patients with longstanding ED were included.
Objective: This study examines treatment effects in STAIR Narrative Therapy (SNT), a phase-based treatment where Skills Training in Affective and Interpersonal Regulation (STAIR) precedes Narrative Therapy (NT), compared to Prolonged Exposure (PE) and to STAIR.
Method: Ninety-two adult patients diagnosed with DSM-5 PTSD and ICD-11 CPTSD following childhood abuse were randomly assigned to enhanced versions of SNT (12 group STAIR sessions + 8 individual NT sessions), PE (8-16 individual sessions), or STAIR (12 group STAIR sessions) provided in residential care. Outcome was assessed by mixed models.
Statistical methods are a cornerstone of research in clinical psychology and are used in clinical trials and reviews to determine the best available evidence. The most widespread statistical framework, frequentist statistics, is often misunderstood and misused. Even when properly applied, this framework can lead to erroneous conclusions and unnecessarily prolonged trials.

We conducted a longitudinal two-waves survey among a sample of 574 migrants and multilevel modelling was used to analyse anxiety, health anxiety and depressive symptoms. Demographic and psychological predictors were investigated.
View Article and Find Full Text PDFBackground: Patients with eating disorders and childhood trauma have clinical presentations that make them less suitable for standard eating disorder treatment. This might be due to high levels of shame and self-criticism. Self-compassion can be a mechanism of change, especially for patients with eating disorders and childhood trauma.

A sample of 1706 individuals completed daily measures during a 40-day period with strict mitigation protocols. Data of 1368 individuals who completed at least 30 assessments were analyzed with the multilevel vector autoregressive (mlVAR) model.

Using Latent Change Score Models to analyze 26,166 observations, the study empirically corroborates that critical fluctuations in depressive symptomatology within and across individuals occur during the first 3 months of the pandemic, after which symptom profiles are predominantly consolidated throughout the pandemic period. Contrary to established belief, female sex, young age, lower education and preexisting psychiatric diagnosis only served as adequate predictors of the initial shocks to symptomatology observed during the onset of the pandemic and did not adequately predict subsequent change observed in symptoms within and across individuals.

We used a sample of 4361 Norwegian adults recruited online and stratified to be nationally representative to investigate the evolution of anxiety following each modification in national SDPs across a 20-month period from the onset of the pandemic to the reopening of society and discontinuation of SDPs. The mean anxiety level fluctuated throughout the observation period and these fluctuations were related to the stringency of the modified SDPs.

Methods: In total, 62 of the 80 living patients (78% response rate) with anorexia nervosa (n = 23), bulimia nervosa (n = 25), or other specified feeding or ED (n = 14) at baseline were evaluated during hospital treatment and at 1-year, 2-year, 5-year, and 17-year follow-up. PD were assessed using the Structured Clinical Interview for DSM-IV Axis II disorders, and the eating disorder examination (EDE) interview was used to assess ED.
The present study investigates differences in the trajectories of anxiety, depression, and sleep problems among infected versus non-infected case-controlled individuals. Patients who tested positive for COVID-19 were selected from a representative sample in Norway (N > 10,000). In total, 126 of these individuals were infected during the project period, and this group was analyzed at T5 (May 2021).

Although these qualities are highly relevant for researchers in child and adolescent mental health, Bayesian methods are still quite rarely employed. This editorial perspective will briefly describe what is different about Bayesian statistical methods, discuss some of the ways they may benefit research in our field, and provide an introduction to how Bayesian statistics are employed in practical research.

One way to formulate emotional distress symptoms is to view them as state manifestations of underlying personality traits. However, the metacognitive model suggests that emotional distress is maintained by metacognitive strategies directed by underlying metacognitive beliefs.
View Article and Find Full Text PDFTo address the increased levels of depressive symptoms during the COVID-19 and other pandemics, it is useful to identify the psychological processes that may explain the relationship between pandemic-related stressors and symptoms. In this study, both the combined network of metacognitions and maladaptive coping strategies-derived from the metacognitive therapy model-and the depressive symptoms were studied during the COVID-19 related lockdown and the partial reopening of the Norwegian society about 3 months later. In an online survey, 4936 participants responded at both these time points.
