International Journal of Methods in Psychiatric Research, Journal Year: 2024, Volume and Issue: 33(4)

Published: Nov. 14, 2024

Abstract Network approaches to psychopathology have become increasingly common in mental health research, with many theoretical and methodological developments quickly gaining traction. This article illustrates contemporary practices applying network analytical tools, bridging the gap between concepts their empirical applications. We explain how we can use graphs construct networks representing complex associations among observable psychological variables. then discuss key models, including dynamic networks, time‐varying models derived from panel data, intervention analysis, latent moderated models. In addition, Bayesian role causal inference a focus on cross‐sectional data. After presenting different methods, theories meaningfully inform each other. conclude discussion that summarizes insights technique provide research.

The future of psychological treatments: The Marburg Declaration

Clinical Psychology Review, Journal Year: 2024, Volume and Issue: 110, P. 102417 - 102417

Published: March 25, 2024

Although psychological treatments are broadly recognized as evidence-based interventions for various mental disorders, challenges remain. For example, a substantial proportion of patients receiving such do not fully recover, and many obstacles hinder the dissemination, implementation, training treatments. These problems require those in our field to rethink some basic models disorders their treatments, question how research practice clinical psychology should progress. To answer these questions, group experts convened at Think-Tank Marburg, Germany, August 2022 review evidence analyze barriers current future developments. After this event, an overview state-of-the-art was drafted suggestions improvements specific recommendations were integrated. Recommendations arising from meeting cover further improving through translational approaches, methodology, bridging gap between more nomothetic (group-oriented) studies idiographic (person-centered) decisions, using network approaches addition selecting single mechanisms embrace complexity reality, making use scalable digital options assessments interventions, education psychotherapists, accepting societal responsibilities that has national global health care. The objective Marburg Declaration is stimulate significant change regarding understanding with aim trigger new era interventions.

New diagnosis in psychiatry: beyond heuristics

Psychological Medicine, Journal Year: 2025, Volume and Issue: 55

Published: Jan. 1, 2025

Abstract Background Diagnosis in psychiatry faces familiar challenges. Validity and utility remain elusive, confusion regarding the fluid arbitrary border between mental health illness is increasing. The mainstream strategy has been conservative iterative, retaining current nosology until something better emerges. However, this led to stagnation. New conceptual frameworks are urgently required catalyze a genuine paradigm shift. Methods We outline candidate strategies that could pave way for such These include Research Domain Criteria (RDoC), Hierarchical Taxonomy of Psychopathology (HiTOP), Clinical Staging, which all promote blend dimensional categorical approaches. Results alternative still heuristic transdiagnostic models provide varying levels clinical research utility. RDoC was intended framework reorient beyond constraints DSM. HiTOP began as derived from statistical methods now pursuing Staging aims both expand scope refine diagnosis by inclusion dimension timing. None yet fit purpose. Yet they relatively complementary, it may be possible them operate an ecosystem. Time will tell whether have capacity singly or jointly deliver Conclusions Several developed separately synergistically build infrastructure enable new define structure, development, mechanisms disorders, guide treatment meet needs patients, policymakers, society.

Schizotypal Traits, Psychopathology, and Reflective Functioning Impairments During Adolescence: A Bayesian Network Approach

Schizophrenia Bulletin, Journal Year: 2025, Volume and Issue: 51(Supplement_2), P. S214 - S225

Published: March 1, 2025

New theoretical and measurement models related to Bayesian networks can usefully be implemented enrich our understanding of psychosis risk. The present study aims explore, using a directed acyclic graph (DAG), the putative causal relationship within schizotypal facets, as well between dimensions, psychopathology, reflective functioning (RF) impairments, in representative sample non-clinical adolescents. A 1476 adolescents from general population participated cross-sectional survey. Oviedo Schizotypy Assessment Questionnaire-Revised, Strengths Difficulties Questionnaire, Reflective Functioning Questionnaire (RFQ) were used. Schizotypal traits positively associated with psychopathology hypomentalizing. Putative relationships are presented Reality distortion, Social disorganization, Anhedonia. In addition, estimated DAG suggests that dimensions influence RF impairments. findings suggest different pathways connecting traits, mental health problems, impairments during adolescence. use probabilistic may allow us make more robust conclusions about direction causation unravel potentially complex chains

Abstract The Self and its Disorders develops a philosophical interdisciplinary approach to the formulation of an “integrative” perspective in psychiatry. In contrast some integrative approaches that focus on narrow brain-based conceptions, or strictly symptomology, this book takes bearings from embodied enactive conceptions human experience builds understands self as self-pattern—a pattern processes include bodily, experiential, affective, cognitive-psychological, reflective, narrative, intersubjective, ecological, normative factors. It provides analysis notion self-pattern, framed terms dynamical organization. then draws phenomenological, developmental, clinical, experimental evidence propose method for studying effects psychopathologies includes discussions network theory, predictive processing models, role narrative.

So You Want to Do ESM? 10 Essential Topics for Implementing the Experience-Sampling Method

Advances in Methods and Practices in Psychological Science, Journal Year: 2024, Volume and Issue: 7(3)

Published: July 1, 2024

The experience-sampling method (ESM) captures psychological experiences over time and in everyday contexts, thereby offering exciting potential for collecting more temporally fine-grained ecologically valid data research. Given that rapid methodological developments make it increasingly difficult novice ESM researchers to be well informed about standards of research identify resources can serve as useful starting points, we here provide a primer on 10 essential design implementation considerations studies. Specifically, (a) compare with cross-sectional, panel, cohort approaches discuss regarding (b) item content phrasing; (c) choosing formulating response options; (d) timescale (sampling scheme, sampling frequency, survey length, study duration); (e) change properties stationarity; (f) power effect sizes; (g) missingness, attrition, compliance; (h) assessment administration; (i) reliability; (j) replicability generalizability. For all topics, challenges and—if available—potential solutions literature points in-depth readings. We also share access living, web-based library extensive catalogue facilitate further learning the ESM. Finally, list topics although beyond scope our article, relevant success Taken together, article highlights most studies, aids identification readings, support quality future

Methodological and Statistical Practices of Using Symptom Networks to Evaluate Mental Health Interventions: A Review and Reflections

Multivariate Behavioral Research, Journal Year: 2024, Volume and Issue: 59(4), P. 663 - 676

Published: May 11, 2024

The network approach to psychopathology, which assesses associations between individual symptoms, has recently been applied evaluate treatments for mental disorders. While various options conducting analyses in intervention research exist, an overview and evaluation of the approaches are currently missing. Therefore, we conducted a review on research. Studies were included if they constructed symptom network, analyzed data that collected before, during or after treatment disorder, yielded information about effect. 56 studies reviewed regarding their methodological analytic strategies. About half based from randomized trials analysis, while other compared networks groups. majority estimated cross-sectional networks, even when repeated measures available. All but five investigated group level.
