The sustainability motive-alignment hypothesis posits that adolescents will be motivated to act sustainably when they view sustainable behavior as aligned with their motives for autonomy and peer status. Based on this hypothesis, we developed the Sustainability Motive-Alignment Scale (SMAS), a brief self-report scale of individual differences in…

Purpose: Standardised questionnaires are used to measure the outcomes of citizenship education. These outcomes are often compared across groups to document different outcomes, for example, between boys and girls. A prerequisite for cross-group comparisons is an assessment of measurement invariance. Methodology: This study used data from 6035…

In this study we measured the effect of COIL on intercultural competence development using a quasi-experimental design. Our sample consisted of 108 undergraduate students from two universities, one located in the Netherlands (NL) and one in the United States (US). Students' self-reported intercultural competence was measured using a pre-post…

This paper presents a cross validation study of four instruments commonly used to assess educator proficiency in technology integration. Data for the validation study were contributed by 357 teacher preparation candidates enrolled in university coursework in the Netherlands. Factor analysis, multidimensional scaling, reliability analyses and…

The goal of the study was to deliver and validate a new solution-focused instrument, the Focus Skills Questionnaire (FSQ), to assess the degree of executive functioning skills in the school context, for three different education levels (elementary, secondary, and tertiary education) and informant groups (students, teachers and parents) on a sample…

The present study addresses creativity as an employee strategy adopted to deal with challenges and distinguishes between incremental creativity (i.e., minor modifications to existing practices) and radical creativity (i.e., major departures from current practices). We hypothesize that employee self-reported mindfulness and other-rated personal…

This study investigates the life purposes and values of higher education students in the Netherlands and Finland (n[subscript Dutch] = 663, n[subscript Fin] = 846). The theoretical framework is built on the conceptualisation of life purpose by Damon et al. as well as Schwartz's values model. The study adopted a convergent mixed methods design…

Participants filled in an online questionnaire. Multiple Regression Analyses showed that…

Important adolescents' career-related decisions might be influenced by their beliefs about malleability of intelligence and learning (mindset). We combined quantitative and qualitative data to provide in-depth insights in the beliefs that 13- and 14-year olds hold about learning and intelligence, the factors influencing these beliefs, and the…

Negative self-esteem is an important transdiagnostic factor underlying various youth psychological problems. Most studies so far have examined the role of more conscious, explicit self-esteem, assessed with self-report questionnaires. Our study investigated the role of explicit as well as implicit self-esteem (with Rosenberg's self-esteem scale…

Differentiated instruction is considered to be an important teaching quality domain to address the needs of individual students in daily classroom practices. However, little is known about whether differentiated instruction is empirically distinguishable from other teaching quality domains in different national contexts. Additionally, little is…

The aim of the present study was to examine whether early adolescents' positive development (i.e., resilience and psychological wellbeing) could be enhanced by stimulating three dimensions of self-awareness: emotional self-regulation, self-esteem, and self-reflection. An experimental field study (randomized controlled trial) was conducted. Seventh…

This study was aimed at validating the Individual Recovery Outcomes Counter (I.ROC) for deaf, hard-of-hearing, and tinnitus patients in a mental health care setting. There is a need for an accessible instrument to monitor treatment effects in this population. The I.ROC measures recovery, seeing recovery as a process of experiencing a meaningful…

The role of motivation, temperament, personality and well-being as predicting propensity factors for mathematical abilities was investigated in 30 adults. By embedding these predictors in the Opportunity-Propensity framework, this study aimed to reveal their unique contribution in math development, which is important to improve mathematics…

The aim of the study is to illustrate a comprehensive approach to item bias in cross-cultural research by integrating quantitative and qualitative data in a mixed methods design. We studied responses and response processes of Dutch and Spanish participants to quality of life items from five international studies. Item bias was evaluated by…
