Abstract Background Signs and symptoms of psychopathology can be chronic but are generally regarded as less stable over time than markers of cognitive vulnerability and personality. Some findings suggest that these differences in temporal stability are modest in size but a rigorous examination across concepts is lacking. The current study investigated the temporal stability of affective symptoms, cognitive vulnerability markers and personality traits at various assessments over nine years. Metho...

Background Psychometric theory offers a range of tests that can be used as supportive evidence of both validity and reliability of instruments aimed at measuring patient-reported outcomes (PRO). The aim of this paper is to illustrate psychometric tests within the Classical Test Theory (CTT) framework, comprising indices that are frequently applied to assess item- and scale-level psychometric properties of PRO instruments.

Background The course of health-related quality of life (HRQOL) during and after completion of neoadjuvant chemoradiotherapy (nCRT) for esophageal or junctional carcinoma is unknown.
Abstract Objective: Physicians are increasingly expected to share uncertain information, yet there is concern about possible negative effects on patients. How uncertainty is conveyed and by whom may influence patients’ response. We tested the effects of verbally and non-verbally communicating uncertainty by a male vs . female oncologist on patients’ trust and intention to seek a second opinion. Methods: In an experimental video vignettes study conducted in The Netherlands, oncologist communicati...

Abstract Objective To examine whether the use of persuasive messages in which cancer patients’ attitudes and perceived social norms were either simultaneously or exclusively targeted can positively change patients’ attitudes, perceived social norms and the intention to express concerns in consultations. Methods Two online experiment s were conducted. The first experiment had a pre-test and post-test measurements design with 4 conditions (attitudes message, social norms message, combined message,...

Background Video vignettes are used to test the effects of physicians’ communication on patient outcomes. Methodological choices in video-vignette development may have far-stretching consequences for participants’ engagement with the video, and thus the ecological validity of this design. To supplement the scant evidence in this field, this study tested how variations in video-vignette introduction format and camera focus influence participants’ engagement with a video vignette showing a bad new...

Previous findings suggest immigrant patients have lower trust in their physicians, and perceive nonverbal communication differently compared to non-immigrant patients. We tested discrepancies in trust and the impact of non-verbal behavior between immigrants and non-immigrants in The Netherlands. Nonverbal communication of an oncologist was systematically varied in an experimental video vignettes design. Breast cancer patients (n = 34) and healthy women (n = 34) viewed one of eight video versions...

Previously, a total of 121 children with an autism spectrum disorder (ASD) performed an adaptive working memory (WM)-training, an adaptive flexibility-training, or a non-adaptive control (mock)-training. Despite overall improvement, there were minor differences between the adaptive and mock-training conditions. Moreover, dropout was relatively high (26%). In the current study we explored potential predicting and moderating factors to clarify these findings. The effects of intelligence, autism tr...
