<b>Objective</b> To investigate whether language used in science abstracts can skew towards the use of strikingly positive and negative words over time. <b>Design</b> Retrospective analysis all scientific PubMed between 1974 2014. <b>Methods</b> The yearly frequencies positive, negative, neutral (25 preselected each category), plus 100 randomly selected were normalised for total number abstracts. Subanalyses included pattern quantification individual words, specificity high...
Codes of conduct mainly focus on research misconduct that takes the form fabrication, falsification, and plagiarism. However, at aggregate level, lesser forms misbehavior may be more important due to their much higher prevalence. Little is known about what most frequent misbehaviors are impact if they occur. A survey was conducted among 1353 attendees international integrity conferences. They were asked score 60 according views perceptions frequency occurrence, preventability, truth...
There is increasing evidence that scientific misconduct more common than previously thought. Strong emphasis on productivity may increase the sense of publication pressure. We administered a nationwide survey to Flemish biomedical scientists whether they had engaged in and experienced A total 315 participated survey; 15% respondents admitted fabricated, falsified, plagiarized, or manipulated data past 3 years. Fraud was among younger working university hospital. Furthermore, 72% rated...
Publication of scientific research papers is important for professionals working in academic medical centres. Quantitative measures output determine status and prestige, serve to rank universities as well individuals. The pressure generate maximum high, quantitative aspects may tend dominate over qualitative ones. How this influences professionals' perception science their personal well-being unknown.We performed an online survey inviting all professors (n = 1206) the 8 centres Netherlands...
Personality influences decision making and ethical considerations. Its influence on the occurrence of research misbehavior has never been studied. This study aims to determine association between personality traits self-reported questionable practices misconduct. We hypothesized that narcissistic, Machiavellianistic psychopathic as well self-esteem are associated with misbehavior.Included in this cross-sectional design were 535 Dutch biomedical scientists (response rate 65%) from all...
Many randomized controlled trials (RCTs) are biased and difficult to reproduce due methodological flaws poor reporting. There is increasing attention for responsible research practices implementation of reporting guidelines, but whether these efforts have improved the quality RCTs (e.g., lower risk bias) unknown. We, therefore, mapped risk-of-bias trends over time in RCT publications relation journal author characteristics. Meta-information 176,620 published between 1966 2018 was extracted....
Although job-related burnout and its core feature emotional exhaustion are common among medical professionals compromise job satisfaction professional performance, they have never been systematically studied in professors, who central positions academic medicine.We performed an online nationwide survey inviting all 1206 professors The Netherlands to participate. They were asked fill out the Maslach Burnout Inventory, a 'professional engagement' inventory, provide demographic job-specific...
Objective To investigate the biomedical scientist's perception of prevailing publication culture. Design Qualitative focus group interview study. Setting Four university medical centres in Netherlands. Participants Three randomly selected groups scientists (PhD, postdoctoral staff members and full professors). Main outcome measures themes for discussion were by participants. Results Frequently perceived detrimental effects contemporary culture strong on citation (like Journal Impact Factor...
Publications determine to a large extent the possibility stay in academia ("publish or perish"). While some pressure publish may incentivise high quality research, too much publication is likely have detrimental effects on both scientific enterprise and individual researchers. Our research question was: What level of perceived four academic institutions Amsterdam does differ between ranks disciplinary fields? Investigating researchers with revised Publication Pressure Questionnaire, we find...
Breaches of research integrity have shocked the academic community. Initially explanations were sought at level individual researchers but over time increased recognition emerged important role that climate may play in influencing researchers' (mis)behavior. In this study we aim to assess whether from different ranks and disciplinary fields experience differently. We sent an online questionnaire Amsterdam using Survey Organizational Research Climate. Bonferroni corrected mean differences...
Abstract Research integrity (RI) is usually discussed in terms of responsibilities that individual researchers bear towards the scientific work they conduct, as well institutions have to enable those do so. In addition these two bearers responsibility, a third category often surfaces, which variably referred culture and practice . These notions merit further development beyond residual contain everything not covered by attributions individuals institutions. This paper discusses how thinking...
Abstract The widespread problems with scientific fraud, questionable research practices, and the reliability of results have led to an increased focus on integrity (RI). International organisations networks been established, declarations issued, codes conducts formed. abstract principles these documents are now also being translated into concrete topic areas that Research Performing (RPOs) Funding (RFOs) should on. However, so far, we know very little about disciplinary differences in need...
Background Many psychiatrists are worried their patients, at increased risk for COVID-19 complications, precluded from receiving appropriate testing. There is a lack of epidemiological data on the associations between psychiatric disorders and testing rates outcomes. Aims To compare probability results among individuals with those without such diagnoses, to examine diagnoses. Method This population-based study perform association analyses disorder diagnoses test results, by using two-sided...
The research climate plays a key role in fostering integrity research. However, little is known about what constitutes responsible climate. We investigated academic researchers' perceptions on this through focus group interviews. recruited researchers from the Vrije Universiteit Amsterdam and University Medical Center to participate discussions that consisted of similar ranks disciplinary fields. asked participants reflect characteristics climate, barriers they perceived which interventions...
This opinion piece aims to inform future research funding programs on responsible practices (RRP) based three specific objectives: (1) give a sketch of the current international discussion (RRPs); (2) an overview initiatives and already obtained results regarding RRP; (3) potential needs for RRP. In this piece, we have used seven iterative methodological steps (including literature review, ranking, sorting exercises) create proposed agenda. We identified six main themes that believe need...
The power of language to modify the reader’s perception interpreting biomedical results cannot be underestimated. Misreporting and misinterpretation are pressing problems in randomized controlled trials (RCT) output. This may partially related statistical significance paradigm used clinical centered around a P value below 0.05 cutoff. Strict use this lead strategies researchers describe their with values approaching but not reaching threshold “almost significant.” question is how phrases...
Reports of questionable or detrimental research practices (QRPs) call into question the reliability scientific evidence and trustworthiness research. A critical component ecosystem is organization within which takes place. We conducted a survey to explore attitudes beliefs European American researchers about organisations in they work, their own towards integrity policies.
Background: Psychologists play a crucial role in providing essential psychological aid to individuals navigating the challenges posed by COVID-19 pandemic. However, studies focusing on mental health of psychologists during pandemic remain scarce. This study investigates interaction between coping strategies and distress among group Indonesian psychologists.

While some fields have led way introduced various practices procedures, call for efforts to ‘improve’ in has not come without criticisms. Generally, there ample ambiguity about desired most productive make progress with research. To study desirable towards this progress,the current uses future studies methodology...
