Area of Science:

  • Psychology
  • Computer Science
  • Measurement Theory

Background:

  • Increasing mobile phone usage correlates with negative effects like problematic mobile phone use.
  • Existing measurement tools, often paper-and-pencil based on Classical Test Theory (CTT), have limitations.
  • There is a need for more precise and efficient methods to assess problematic mobile phone use.

Purpose of the Study:

  • To develop a Computerized Adaptive Test for problematic mobile phone use (CAT-PMPU) utilizing Item Response Theory (IRT).
  • To evaluate the performance and measurement efficiency of the CAT-PMPU.
  • To compare the accuracy and reliability of CAT-PMPU against traditional paper-and-pencil tests.

Main Methods:

  • Development of the CAT-PMPU based on Item Response Theory (IRT).
  • Simulation of CAT using real-world data.
  • Comparative analysis of measurement accuracy and reliability between CAT-PMPU and paper-and-pencil tests under identical test lengths.

Main Results:

  • CAT-PMPU demonstrated superior performance compared to traditional paper-and-pencil tests across all evaluated aspects.
  • The CAT-PMPU effectively reduces the number of items required for assessment.
  • Measurement efficiency was significantly improved using the CAT-PMPU.

Conclusions:

  • The developed CAT-PMPU exhibits good reliability and offers a more efficient measurement of problematic mobile phone use.
  • This study provides novel technical support for assessing problematic mobile phone use.
  • CAT-PMPU shows significant potential for practical application in the field.
