The transition from financial dependence on one's parents to financial self-sufficiency is one of the most relevant transitions during emerging adulthood. It is important to have an instrument able to assess emerging adults' financial capabilities and to detect its change over time. The current article aims to collect international evidence of the…

Background: The present study examined the psychometric properties of the Dynamic Risk Outcome Scales (DROS ), an instrument developed to measure dynamic risk factors in individuals with mild intellectual disabilities or borderline intellectual functioning (MID -BIF ) and externalizing (including offending-like) behaviour problems. Method: The…

Background: Structured assessments have been shown to assist professionals to evaluate the risk of aggression in secure services for general offender populations and more recently among adults with intellectual disabilities. There is a need to develop intellectual disability sensitive measures for predicting risk of aggression in community…

When first learning how to write mathematical proofs, it is often easier for students to work with statements using the universal quantifier. Results that single out special cases might initially come across as more puzzling or even mysterious. In this article we explore three specific statements from abstract algebra that involve the number…

The purpose of this study was to determine the validity and reliability of the Power Walker® 610(PW) pedometer for step counting in children. The study sample was composed of 30 boys and 22 girls, from 8-13 years old. Participants were equipped with both a PW and a Digiwalker® SW-200(DW) pedometers and walked 400 m around an outdoor athletic track…

Psychological flexibility (PF), teaching resiliency (tRES), and sense of purpose (SOP) are characteristics that influence physical education teaching sustainability. The study's purpose was to validate an instrument measuring PF, tRES, and SOP relative to teachers' intent to remain teaching (IRT) in high poverty (>60% low-income) schools and…

Concurrent enrollment programs, which allow college credit-bearing classes to be offered in the high school taught by qualified high-school teachers, are a potential solution to the student debt issues impacting the United States and other countries.

The authors developed and initially validated the Supervisee Disclosure in Supervision Scale (SDSS). Exploratory and confirmatory factor analyses with 2 independent samples revealed that the SDSS is a 17-item instrument with 2 subscales showing promising psychometric properties. The authors discuss the findings with implications for supervision…

This study was conducted to describe the validation of learning environment inventory (LEI) for secondary school contexts. A survey method was used for data collection through the 20-item LEI. This study consists of two phases. In Phase 1, an exploratory factor analysis (EFA) was conducted using the Statistical Package for Social Sciences (SPSS…

Developing communication skills is critical for all young children, especially for those receiving early intervention (EI) services. Thus, many researchers have investigated evidence-based practices for teaching social communication skills. In an attempt to minimize the gap between research and practice, research investigating training caregivers…

In order to reach valid and reliable test scores, various test theories have been developed, and one of them is nonparametric item response theory (NIRT). Mokken Models are the most widely known NIRT models which are useful for small samples and short tests. Mokken Package is useful for Mokken Scale Analysis. An important issue about validity is…

The purpose of this study was to develop a questionnaire to assess body posture habits in adolescents' daily activities. To develop and assess the instrument we used the Delphi method, and a test-retest reliability design. The questionnaire consisted of 31 questions with 4-level Likert scale. One hundred and sixty-eight students were studied, 72…

Background: Families of children with disabilities often face unique challenges. Developed in a U.S. context, the Beach Center Family Quality of Life measure assesses the effectiveness of supports and services that families receive. This study examines whether items from three sub-scales of the Beach Center instrument perform similarly for two…
