Writing the theoretical rationale for a study can be a daunting prospect for novice researchers. Nursing's conceptual models provide excellent frameworks for placement of study variables, but moving from the very abstract concepts of the nursing model to the less abstract concepts of the study variables is difficult. Similar to the five-paragraph essay used by writing teachers to assist beginning writers to construct a logical thesis, the authors of this column present guidelines that beginners can follow to construct their theoretical rationale. This guide can be used with any nursing conceptual model but Neuman's model was chosen here as the exemplar.

Towards an understanding of readiness for trauma-focussed therapy in post-traumatic stress disorder: A conceptual integration of empirical data and theoretical constructs.
Clin Psychol Rev
December 2024
Orygen, 35 Poplar Rd, Parkville, Victoria 3052, Australia; Centre for Youth Mental Health, The University of Melbourne, Victoria 3010, Australia. Electronic address:
For people with post-traumatic stress disorder (PTSD), the concept of being 'ready' for trauma-focused therapy (TFT) has emerged from research as an important factor in initiation and completion of therapy. Lack of readiness of individual service users has been proposed as a reason for poor uptake of TFT in large implementation programs. However, there has been almost no investigation of what constitutes readiness for TFT.

J Eval Clin Pract
February 2025
California State University Monterey Bay, Seaside, California, USA.
Rationale: Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.
Aims And Objectives: Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.
The factor structure of the International Trauma Questionnaire - Heywood cases in confirmatory factor analysis.
Eur J Psychotraumatol
December 2025
Research and Knowledge Centre, Danish Veterans Centre, Ringsted, Denmark.
A number of studies have tested the factor structure of the suggested ICD-11 symptom criteria for PTSD and complex PTSD (CPTSD) across various trauma populations, finding support for two different models in line with the ICD-11 theoretical rationale. Here, we aim to explore the factor structure of the Danish version of the International Trauma Questionnaire (ITQ) by testing two alternative factor models that have previously gained support in a large sample of treatment-seeking veterans. Treatment-seeking Danish soldiers and veterans ( = 599) recruited from the Military Psychology Department in the Danish Defence completed the International Trauma Questionnaire (ITQ).

Beijing National Laboratory for Molecular Science (BNLMS), State Key Laboratory for Structural Chemistry of Unstable and Stable Species, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, China.
Article Synopsis
- Clusters are key for understanding how the structure of materials relates to their properties, especially at the atomic level.
- There’s growing interest in stable clusters, but this isn’t the same for all transition metal clusters.
- Research on pure tantalum clusters showed that their stability and interactions with dinitrogen involve complex electronic behaviors and reaction dynamics, aiding insights for creating materials that can effectively resist nitrogen.
Comprehensive Insights into Mechanisms for Ventricular Remodeling in Right Heart Failure.
Rev Cardiovasc Med
December 2024
Department of General Medicine, First Affiliated Hospital of Xinjiang Medical University, 830011 Urumchi, Xinjiang, China.
Article Synopsis
- Ventricular remodeling in right heart failure (RHF) is a complex process involving neuro-hormonal activation, oxidative stress, cytokine expression, cardiomyocyte apoptosis, and changes in the extracellular matrix.
- This remodeling leads to myocardial hypertrophy and fibrosis, which negatively impacts heart function.
- Understanding these mechanisms is crucial for developing better treatments to enhance survival and quality of life for RHF patients, though research in this area remains limited.
