The purpose of the current study is to validate a measure of sensory processing sensitivity, the Highly Sensitive Person Scale, with a sample of high-ability individuals. Participants include 188 highly intelligent individuals. Results indicate a two-factor structure of the Highly Sensitive Person Scale. Validity and reliability evidence are…

Sleep problems are common in children with autism spectrum disorder (ASD) and adversely impact daytime functioning. Although no questionnaires have been developed to assess sleep in children with ASD, the 33-item Children's Sleep Habits Questionnaire (CSHQ) is widely used in this population. We examined the factor structure of the CSHQ in 2872…

The assumption of longitudinal measurement invariance underlies the interpretation of changes in assessment scale score levels over time. This study was conducted to examine the longitudinal measurement invariance of the "SuccessNavigator"® assessment (SN) in a sample of 407 first-year undergraduate students. SN is a psychosocial skills…

Transition from high school to college can be very challenging for Turkish students, and poor adjustment can affect students' physical and mental health and well-being. It is important for college counseling center staff in Turkey to have access to screening instruments to identify students with high risk for college life adjustment difficulties.…

This study analyzed the psychometric properties of the Italian translation of both the Short Almost Perfect Scale (SAPS) and the Short Multidimensional Perfectionism Scale (SMPS), and the academic implications of perfectionism on 414 Italian college students aged between 18 and 58 years. Results revealed some limitations with the SAPS factor…

While research to date on school leadership has identified instructional leadership as an effective means to improve academic achievement, little is known about how teachers and principals view instructional leadership both individually and collectively. We analyzed the OECD Teaching and Learning International Survey (TALIS) of 2008 of 59,152…

The aim of the study is to adapt the School Kindness Scale (SKS) to Turkish, and to examine its psychometric properties. For this purpose, two separate samples were used. Totally, 611 middle school students (302 boys, corresponding to 49.43% and 309 girls, corresponding to 50.57%) participated in the Study 1, and 759 middle school students (369…

Construct validation evidence for the Intercultural Development Inventory (IDI) offers support for the use of the IDI to assess individuals' ability to observe differences and similarities, and adapt behavior to cultural context. This review offers researchers and practitioners the information needed to make an informed decision about using the…

Background: Materialism is a topic of interest for many scholars. Among children it is often measured with the Material Values Scale for children (MVS-c) (Opree et al. in Personal Individ Differ 51(8):963-968, 2011). Although the MVS-c was originally validated for use among 8- to 12-year-olds, its 6-item version is increasingly implemented among…

Theories of reading and writing development suggest that the factor structure of achievement batteries could change across development. As a result, it is important to test achievement batteries for invariance across development. The purpose of these analyses is to determine whether the factor structure of reading, writing, and oral language…

The study aims to examine the interplay of two critical constructs in evaluation: essential evaluator competency and evaluator practice. The research questions in this study, according to Smith (2008), are essentially, what he defined as "fundamental issues in evaluation." These issues fall into one or multiple of the four aspects…

This study explores the psychometric properties of "Self-Determination Inventory: Student Report" (SDI:SR) in students with intellectual and developmental disabilities (IDD) and without disabilities in China. The paper-and-pencil version of SDI:SR Chinese Translation (SDI:SR Chinese) was used to explore self-determination across students…

For decades, achievement goal theory has been extensively used, but empirical research still requires a clearer understanding of the underlying factors conceptualized and measured during secondary school periods. In light of the increasing use of longitudinal studies in motivation research, this study aims to investigate the longitudinal…

This study aims to develop a valid and reliable measuring instrument that can measure the level of mathematical language used by students and their teachers during the teaching of fractions to fourth-grade primary school students. This study is a methodological validity and reliability study. In total, 999 students from fourteen different…

The Flourishing Scale is a new scale designed to measure psychological well-being. FS has been translated into more than 10 languages (e.g., Portuguese, Russian, Turki, Spanish, Egyptian, French, Chinses, Japanese, Malay, Urdu, and Persian). The psychometric analysis of the Flourishing Scale has not been explored in the Malaysian context. The aims…
