Validated Instruments for Problematic Digital Media Use in Elementary School Children
The term “brain rot” is increasingly used to describe concerns about excessive consumption of low‐quality digital content and its cognitive, behavioral, and educational effects in children. However, brain rot is not an established clinical construct, and no validated instruments have been specifically designed to measure it. Existing studies instead use related constructs, such as digital addiction, problematic internet use, gaming disorder, smar…
Influence of mothers' positive parenting on adolescents' future orientation
Indonesia is expected to benefit from a demographic transition that will result in a large proportion of the population entering the workforce by 2045, with approximately 70% of its population falling within the working-age population. To capitalize on this opportunity, high-quality education and effective family socialization are essential to prepare a capable generation for future leadership. Previous studies have demonstrated that positive par…
Adaptation and psychometric evaluation of the Indonesian Maladaptive Daydreaming Scale-16 (MDS-16-Ina)
Validation of the Child Development Card (KKA) as a growth and development tool for stunted and normal children in West Java, Indonesia
BACKGROUND: Stunting remains a major public health issue in Indonesia, and the limitations of anthropometric measures highlight the need for alternative tools such as the Child Development Card (KKA). OBJECTIVES: This study aimed to determine the validity and reliability of the KKA as a tool to measure the growth and development of stunted and normal children through direct observation. METHODS: The revised KKA was administered to 262 children ag…
The role of perceived teacher, peer, and parental support in school belonging among vocational high school students
This study investigates the role of perceived support from teachers, peers, and parents in fostering school belonging among vocational high school students. A total of 567 students participated in this research. Data were analysed using Structural Equation Modeling – Partial Least Squares (SEM-PLS). The results indicate that perceived teacher emotional support, perceived teacher instrumental support, and perceived parental emotional support signi…
Initial comparison of psychometric properties of the Japanese Parenting Style Scale (JPSS) in Indonesia and Japan
Parenting style is crucial in shaping children's development, particularly during early childhood. Therefore, this study aims to investigate the psychometric properties of the Japanese Parenting Style Scale (JPSS) and its applicability in cross-cultural contexts, specifically among Indonesian and Japanese mothers. JPSS, comprising four dimensions, namely warmth, hostility, permissiveness, and harsh control, was administered to 1095 female partici…
Evaluation of an environmentally friendly behavior scale among Indonesian university students using the Rasch model
Environmental degradation caused by human activities is becoming increasingly alarming, prompting efforts to address this issue, including understanding human behavior. This study aims to re-evaluate the validity of the Indonesian version of the Environmentally Friendly Behavior (EFB) scale using the Rasch model, which is considered superior to the Classical Test Theory (CTT) approach used in its initial adaptation. A total of 279 students from u…
Development of the Family Function Scale
The unproperly functioning family can provoke adolescent mental health and behavior problems. The measurement of family function in Indonesia still uses instruments from the West, so it is necessary to develop a more suitable community tool. This study aims to validate the Indonesian version of Chinese Family Assessment Inventory. We selected 396 participants randomly from four high schools in Medan. Data analysis showed that all scale items had …
The Development and Initial Validation of the Youth Sexual Intention Scale
Interventions for the early sexual problem in adolescents require proper measurement of sexual intentions. The adolescent sexual intention scales have been widely used by researchers in the West. However, those scales are not very suitable for adolescents in eastern cultures such as Indonesia. As a religious society, Indonesian people have different sexual expectations from liberal western society. Religious teachings and societal norms shape sex…
