A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Area of Science:

  • Psychology
  • Educational Psychology
  • Child and Adolescent Psychiatry

Background:

  • Problematic smartphone use is a growing concern among children.
  • Accurate assessment tools are needed to identify at-risk students.
  • The Smartphone Application-Based Addiction Scale (SABAS) requires psychometric evaluation in diverse populations.

Purpose of the Study:

  • To assess the psychometric properties of the SABAS in Chinese primary school students.
  • To evaluate the validity, reliability, and factor structure of the SABAS.
  • To identify potential gender biases and understand item interrelationships.

Main Methods:

  • A sample of 1108 primary school students in China participated.
  • Item Response Theory (IRT) was used for factor structure, item parameters, and reliability analysis.
  • Network Analysis (NA) explored item interrelationships, and Differential Item Functioning (DIF) assessed gender bias.

Main Results:

  • Confirmatory factor analysis supported a unidimensional structure for the SABAS.
  • IRT analysis demonstrated high item discrimination and established a cut-off score of 27.
  • A small percentage (1.7%) of students were classified as high-risk; gender DIF was observed in one item.

Conclusions:

  • The SABAS is a valid and reliable instrument for assessing problematic smartphone use in Chinese primary school students.
  • The scale is particularly useful for identifying students at moderate to high risk.
  • Findings support the use of SABAS for early intervention and targeted support.
