Introduction: Posting results to clinical trial registers is encouraged and even mandatory for certain trials. This study assessed the feasibility of using structured results data on trial registries over journal articles for meta-analyses using two exemplary approaches. Methods: In study one, we searched ClinicalTrials.gov for studies employing Co...
Patient health literacy is crucial for effective patient–physician communication, and interventions targeting health literacy can use measures based on either actual performance (competence) or self-ratings (confidence). This paper analyzed the development of these measures through three studies. Study 1 reviewed articles describing the development...
'Optimal cutpoints' for binary classification tasks are often established by testing which cutpoint yields the best discrimination, for example the Youden index, in a specific sample. This results in 'optimal' cutpoints that are highly variable and systematically overestimate the out-of-sample performance. To address these concerns, the cutpointr p...
This research, comprising three experiments with a total of 1718 population‐representative participants, investigates the strategies Muslim organizations can utilize to sustain trust and positive perceptions in the direct aftermath of terrorist attacks. It evaluates the effectiveness of different crisis communication strategies as outlined by the S...
Introduction
Intensive interdisciplinary pain treatment (IIPT) is the best therapy available for children and adolescents affected by severe chronic pain. Psychosocial aftercare (PAC) offered for 6 months after IIPT can improve treatment outcomes for up to 12 months.
Objectives
The current study is the first to explore whether PAC is superior to t...

Crisis communication st...
In this study, we describe the development and validation of a revised Pediatric Chronic Pain Grading (P-CPG) for children aged 8 to 17 years that adds emotional impairment to previously used measures of pain intensity and functional impairment. Such a measure enables the assessment of chronic pain severity in different epidemiological and clinical...
Although negative effects of psychological interventions are suspected to be common, they are rarely investigated. Experts and international guidelines agree that monitoring for negative effects in clinical studies is needed to make psychological interventions safer and to empower patients before they give their consent to participate. Therefore, m...
This study explores the reactions to being denied access to medical services, such as skin cancer screenings, as a form of social exclusion. Early detection of skin cancer is crucial for reducing morbidity, treatment costs, and mortality. However, access to these services is not equally distributed, with statutorily insured individuals facing disad...
Objectives
Changes in pain scores that represent clinically significant differences in children with headaches are necessary for study design and interpretation of findings reported in studies. We aimed to determine changes in pain scores associated with a minimum clinically significant difference (MCSD), ideal clinically significant difference (IC...
Background
The dual-factor model of mental health posits that mental health and mental illness constitute two distinct axes; accordingly the model identifies four mental health groups: (1) complete mental health, (2) troubled, (3) vulnerable, (4) symptomatic but content. Yet, only a few studies investigated effectiveness of therapy on both dimensio...

Questions
Question (1)
Many social sciences (Psychology, Business, Sociology, etc.) require their undergraduates to learn some basic quantitative methods (aka stats). This is often coupled with learning to use a software. In psychology SPSS has been the method of choice because many believe that the graphical user interface makes it easier for students to learn, while programming languages such as R are too hard.
I wonder if this is backed by any hard evidence? Working in medicine for some time I would prefer some randomized controlled trials, but for starters anything else would be great.
The outcome I would be most interested in is are they able to apply the methods on their own problems?
