Data from an international multi-centre Study of Statistics and Mathematics Anxieties and Related Variables in University Students (the SMARVUS Dataset)

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and the cognitive reflection test, and collected demographics, previous mathematics grades, self-reported and official statistics grades, and statistics module details. Data reuse potential is broad, including testing links between anxieties and statistics/mathematics education factors, and examining instruments’ psychometric properties across differ…

In Search of Determinants of Time-Discounting in Monetary Choices : Personal Characteristics Matter Only a Little

Time-discounting in monetary choices is determined by aspects related to the reward, contextual factors and characteristics of a person. In the present study, we used three datasets (Ndata1 = 419; Ndata2 = 485; Ndata3 = 240) to examine how well personal characteristics (sociodemographic, financial situation, self-control, cognitive abilities, negative experiencing, and trustfulness) predict time-discounting in both hypothetical and real reward scenarios. The results of the regression analyses indicate that the characteristics of a person only explain a small proportion of the variance in time-discounting (R2 ranged from .10 to .19). The only substantive predictors of time-discounting in mon…

Risk and protective factors for (internet) gaming disorder: A meta-analysis of pre-COVID studies.

This large-scale meta-analysis aimed to provide the most comprehensive synthesis to date of the available evidence from the pre-COVID period on risk and protective factors for (internet) gaming disorder (as defined in the DSM-5 or ICD-11) across all studied populations. The risk/protective factors included demographic characteristics, psychological, psychopathological, social, and gaming-related factors. In total, we have included 1586 effects from 253 different studies, summarizing data from 210557 participants. Apart from estimating these predictive associations and relevant moderating effects, we implemented state-of-the-art adjustments for publication bias, psychometric artifacts, and o…

Measuring Internet Gaming Disorder and Gaming Disorder : A Qualitative Content Validity Analysis of Validated Scales

Numerous instruments have been developed to measure gaming-related health problems based on “internet gaming disorder” (IGD) in the third section of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and “gaming disorder” (GD) in the International Classification of Diseases (11th rev.). However, the criteria in the manuals tend to be operationalized in numerous diverse ways, which can make screening outcomes incomparable. A content validity analysis is needed to reassess the relationships between the diagnostic criteria and the items that operationalize them. The IGD and GD criteria were divided into sematic components. A qualitative content validity analysis was carried ou…

Statistical misconceptions, awareness, and attitudes towards open science practices in Slovak psychology researchers

In the years following the reproducibility crisis in behavioral sciences, increased attention of the scientific community has been dedicated to the correct application of statistical inference and promotion of open science practices. In the present survey, we contacted psychology researchers, lecturers, and doctoral students from all universities in Slovakia and the Slovak Academy of Sciences via email. Together we re-ceived answers from 65 participants. Questions in the survey covered the most common misconceptions about statistical hypothesis testing, as well as awareness, attitudes, and barriers related to the adherence to open science practices. We found a high prevalence of statistical…
