Background: This paper presents a description of the development and psychometric properties of a self-report instrument for the assessment of sexual behaviour and concerns of people with mild intellectual disabilities (SEBECOMID-S). Methods and procedures: The study included 281 people with mild intellectual disabilities. The psychometric…

Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick's Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of…

In the Attentional Boost Effect (ABE), words or images encoded with to-be-detected target squares are later recognized better than words or images encoded with to-be-ignored distractor squares. The present study sought to determine whether the ABE enhanced the encoding of the item-specific and relational properties of the studied words by using…

Introduction: Creativity is a capacity that is related to divergent thinking and is fundamental in the changing society of the 21st century for training competent students who can function in society. There are several psychometric tests for measuring creativity, among which the Creative Intelligence Test (CREA) stands out, which is widely used in…

The purpose of this research was to organize a cross-cultural adaptation study and analyze the reproducibility and test-retest reliability of the Infant Sensory Profile 2 (ISP2Br) to Brazilian babies. It was hypothesized that the instrument would be validated for use with Brazilian babies. The English language version of the profile was translated…

Creativity in science education and research on scientific creativity are becoming increasingly significant. Several domain-specific assessment tools focusing on different aspects of scientific creativity have been developed. Some of these tools consider a wide range of aspects, while others focus on very specific science-related aspects, thereby…

Teacher design work has gained increasing attention by re-conceptualizing teachers as designers rather than curriculum deliverers. However, assessing teacher design work can be challenging given that there are very few research tools to assess teacher design knowledge (TDK) competencies. To fill that gap, this study proposes a survey that assesses…

This study developed and tested a Turkish translation of the 23-item Sahin-Francis Scale of Attitude toward Islam (containing six negatively-voiced items) on data provided by 493 participants (191 school students and 302 undergraduate students). Two research questions were tested on these data. First, exploratory factor analyses suggested that…

Students' test-taking motivation confounds test performance. This study examines students' conceptions of tests and test-taking motivation when different test consequences are at play. In a between-subjects experimental design, a sample of 479 New Zealand senior secondary school students were randomly assigned to one of the three vignette…

Studying epistemically unwarranted beliefs (EUB) is relevant at basic, applied, and social levels. However, EUB scales validated in Spain are scare. Consequently, we aimed to develop and validate a scale of this kind. One thousand four hundred and sixty participants answered to a preliminary version of the questionnaire. Exploratory and…

Differential item functioning (DIF) occurs when the probability of endorsing an item differs across groups for individuals with the same latent trait level. The presence of DIF items may jeopardize the validity of an instrument; therefore, it is crucial to identify DIF items in routine operations of educational assessment. While DIF detection…

Evidence-based maternal and early childhood home visiting (EBHV) may support health and well-being among families headed by a caregiver with an intellectual disability or other learning difference. Little is known about tools EBHV staff can use to identify caregivers with learning differences and inform service delivery strategies. Investigators…

The discussion of whether multiple-choice questions can replace the traditional exam with essays and constructed questions in introductory courses has just started in Norway. There is not an easy answer. The findings depend on the pattern of the questions. Therefore, one must be careful in drawing conclusions. In this research, one will explore a…

The factor structure, the concurrent validity, and test-retest reliability of the Czech translation of the Gifted Rating Scales-School Form [GRS-S; Pfeiffer, S. I., & Jarosewich, T. (2003). "GRS (gifted rating scales) - manual." Pearson] were evaluated. Ten alternative models were tested. Four models were found to exhibit acceptable…

Cell biology is widely considered to be the most important subject for promoting current modern biology. This paper sheds new light on the subject with the development of a diagnostic test to investigate misconceptions among pre-service biology teachers in cell biology. In this study, we developed and validated a diagnostic test -- known as the…
