University students’ learning approaches : An adaptation of the revised two-factor study process questionnaire to Norwegian

2020

This paper reports a Norwegian validation study of a widely used instrument to measure students’ approaches to learning, namely, Bigg’s revised two-factor study process questionnaire (R-SPQ-2F). Its cultural sensitivity and psychometry evaluations have provoked rigorous discussion among educators in different languages. A survey design was adopted involving 253 undergraduate engineering students across two universities. Confirmatory factor analyses were used to test six models hypothesized to reflect the factor structures of R-SPQ-2F and unidimensionality of its subscales. The results showed appropriate fits of a two-factor first-order model with 10 items measuring deep approach and 9 items…

SLFTD: A Subjective Logic Based Framework for Truth Discovery

2019

Finding truth from various conflicting candidate values provided by different data sources is called truth discovery, which is of vital importance in data integration. Several algorithms have been proposed in this area, which usually have similar procedure: iteratively inferring the truth and provider’s reliability on providing truth until converge. Therefore, an accurate provider’s reliability evaluation is essential. However, no work pays attention to “how reliable this provider continuously providing truth”. Therefore, we introduce subjective logic, which can record both (1) the provider’s reliability of generating truth, and (2) reliability of provider continuously doing so. Our propose…

A reliability generalization meta‐analysis of self‐report measures of muscle dysmorphia

2020

This study is a reliability generalization meta‐analysis that reviews continuous measures used to assess muscle dysmorphia (MD): The Muscle Appearance Satisfaction Scale, Muscle Dysmorphic Disorder Inventory, four different versions of the Muscle Dysmorphia Inventory, Adonis Complex Questionnaire, and the Modified Dysmorphia Symptoms Questionnaire. A total of 15,156 individuals from 61 studies provided 73 reliability estimates (alpha coefficients and/or test–retest reliability coefficients) for this meta‐analysis. Random‐ and mixed‐effects models were applied in the statistical analyses. We present the average reliability estimates for each measure, moderator analysis of reliability estimat…

Background: The Self-Regulation of Eating Behavior Questionnaire (SREBQ) is an economical way of assessing an individual's self-regulatory abilities regarding eating behavior. Such scales are needed in the German population; therefore, the purpose of the present study was the translation and validation of a German version of the SREBQ.Method: First, we conducted a pilot study (Study 1; N = 371) after the translation procedure. Second, we assessed the final scale in a representative sample of the German population (Sample 2; N = 2,483) and its underlying factor structure. Further, we tested for measurement invariance and evaluated the SREBQ's associations with related scales to explore conve…

Background The SCL-K-9 is the latest short version of the multidimensional Symptom-Checklist 90-R. Up to now, its psychometric properties have not been clarified sufficiently as the nine items have not yet been presented exclusively in a representative sample. Therefore, psychometric properties, model fit values as well as norm-values were analyzed. Methods For the sample, N = 2,507 participants aged 14 to 92, n = 1,379 women and n = 1,128 men, and a mean age of 48.79 (SD = 17.91), were selected from the general population by random-route sampling. Confirmatory factor analyses applying full information maximum likelihood (FIML) tested the model fit. The reliability estimations and effect si…

Validation of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents

2021

Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of signifi…

Messages beyond the phone: Processing variable message signs while attending hands-free phone calls.

2021

We examined the effects of different types of cognitive distraction coming from a hands-free phone conversation on the processing of information provided by variable message signs (VMS), on driving performance indicators, and on a physiological index of mental effort (heart rate). Participants drove a route in a driving simulator and had to respond to VMS messages under three conditions: no-distraction, visuospatial distraction (attending phone calls with questions inducing visuospatial processing), and conceptual distraction (attending phone calls with questions requiring semantic memory). Results showed more errors responding to VMS messages in the visuospatial distraction condition. In a…

Would New Zealand adolescents cycle to school more if allowed to cycle without a helmet?

2018

Abstract Introduction The effectiveness of bicycle helmet use in preventing head injuries has been well documented. Mandatory helmet-use legislation is present in multiple countries including New Zealand. However, studies examining the correlates of adolescents' perception that they would cycle to school more often if helmet legislation was repealed are scant. This study examined these correlates in a sample of New Zealand adolescents. Methods Adolescents (n = 774; age: 13–18 years) from all 12 secondary schools in Dunedin, New Zealand, completed an online questionnaire about their cycling to school and cycling in general behaviours and perceptions and opinions about bicycle helmet use as a…

Spatial analysis of traffic accidents near and between road intersections in a directed linear network.

2019

Although most of the literature on traffic safety analysis has been developed over areal zones, there is a growing interest in using the specific road structure of the region under investigation, which is known as a linear network in the field of spatial statistics. The use of linear networks entails several technical complications, ranging from the accurate location of traffic accidents to the definition of covariates at a spatial micro-level. Therefore, the primary goal of this study was to display a detailed analysis of a dataset of traffic accidents recorded in Valencia (Spain), which were located into a linear network representing more than 30 km of urban road structure corresponding t…

A GIS-Based Methodology to Estimate the Potential Demand of an Integrated Transport System

2017

In the design of a new public transport system or of an extension of an existing system, the choice of a suitable placement of stations and stops in the territory and the definition of the main axes are very important. The different choice in the number and distribution of the stops of a road transport system or of a railway transport system, in fact, makes the system more or less widespread and affects the consistency of the catchment area and the attractiveness of the system. The accessibility of a system, add to the reliability in providing the service, is the fundamental parameter influencing the modal split of the users. Therefore, the Public Administration must have tools able to eval…
