Measurement invariance allows for the comparison and interpretation of scores obtained from the same scales at different times. In this respect, the purpose of this research is to examine the measurement invariance of the satisfaction with life scale applied to different age groups. The study employs the survey model, a type of quantitative…

The patient health questionnaire-9 (PHQ-9) is widely utilized in assessing individuals' depression levels. Nevertheless, research regarding its factor structure and measurement invariance remains inadequate. The aim of this study was to delve into the factor structure of the PHQ-9 and to further investigate its measurement invariance across gender…

Purpose in life is a key construct in the development of young adults, particularly college students. There are many instruments measuring sense of purpose in life, but few studies have examined their measurement properties among college students. The current study compares the measurement invariance properties of the Purpose in Life (PIL) scale…

This study tested factorial structure, reliability as well as gender, age, and cultural measurement invariance of the Brief Inventory of Thriving (BIT). Data were collected from 981 Italian, Portuguese, and Chinese emerging adults. Results showed that BIT scores were reliable, mono-dimensional, and suitable to assess thriving across different…

Researchers are combining self-reports from mobile surveys with passive data collection using sensors and apps on smartphones increasingly more often. While smartphones are commonly used in some groups of individuals, smartphone penetration is significantly lower in other groups. In addition, different operating systems (OSs) limit how mobile data…

The role of feelings of belonging at school in adolescents' academic and psychological functioning is well established. This study aimed to validate the School Connectedness subscale from the Maryland Safe and Supportive Schools (MDS3) School Climate Survey for secondary school students in Spain. This subscale encompasses the three key dimensions…

The Kaufman Domains of Creativity Scale (K-DOCS; Kaufman, J. C. (2012). Counting the muses: Development of the Kaufman domains of creativity scale (K-DOCS). Psychology of Aesthetics, Creativity, and the Arts, 6(4), 298-308. doi:10.1037/a0029751) is a self-report assessment of five creative domains: Everyday, Scholarly, Performance, Scientific, and…

This article is the fourth in a series arguing that there is serious mismeasurement of enrolment in early childhood development (ECD) and in the early grades of education systems in many countries, especially, and most damagingly, in those making the most progress on access to schooling and in the sustainable development goals. Other reports have…

The Abbreviated Math Anxiety Scale (AMAS) is commonly used to compare groups on math anxiety. Group comparisons should however be preceded by a demonstration of metric and scalar measurement invariance, which is currently only available for undergraduate students in the USA. This study tested for metric and scalar measurement invariance of AMAS…

The Student-Teacher Relationship Scale-Short Form (STRS-SF) is one of the most frequently used instruments globally to measure professional caregivers' perceptions of the relationship quality with a specific child. However, its psychometric properties for children younger than 3 years of age enrolled in early childhood education and care (ECEC)…

Students' perceptions of the learning environment play an important role in their academic achievement and social lives. While most measures of school environment have been developed for middle- and high-school students, they also have been used for younger students, such as 4th and 5th graders. What is unclear is whether these measures are…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

Purpose: Teacher ratings were used to compare children with developmental language disorders (DLD) and their typically developing peers on 2 subtypes of social withdrawal (shyness and unsociability). Measurement invariance analysis was utilized to determine if teachers rated the 2 groups using the same underlying construct for each of the rating…

The study examines the concurrent and longitudinal associations between ratings-based measures (parents, secondary caregivers, and observers) and performance-based measures of focused attention in toddlers aged 30 (n = 147), 36 (n = 127), and 42 months (n = 107). Parents and secondary caregivers rated focused attention behaviours using the…

The Reynolds Intellectual Assessment Scales (RIAS) measures general intelligence and its two main components, verbal and nonverbal intelligence, each comprising of two subtests. The RIAS has been recently standardized in Denmark, Germany, Switzerland, and Spain. Using the standardization samples of the U.S. (n = 2,438), Danish (n = 983), German (n…
