Area of Science:

  • Psychology
  • Public Health
  • Digital Media Studies

Background:

  • Smartphone addiction poses risks to functioning and mental health.
  • Early identification is crucial for timely intervention.
  • No validated tool existed for assessing excessive mobile phone use in India.

Purpose of the Study:

  • To develop and validate the Mobile Phone Use Screening Test (MUST).
  • To provide a screening tool for addictive smartphone use in the Indian context.

Main Methods:

  • A new 18-item self-report Likert-type scale was developed.
  • The study involved 500 participants aged 18-40 in Bangalore, India.
  • Data collected included sociodemographics and patterns of excessive mobile phone use.

Main Results:

  • The MUST demonstrated strong reliability (test-retest: 0.93, Cronbach's alpha: 0.86).
  • Scoring criteria were established: <30 (mild), 31-49 (moderate), ≥50 (excessive/addictive).
  • The scale measures craving, loss of control, coping, and consequences of mobile phone use.

Conclusions:

  • The MUST is a reliable and valid tool for identifying addictive/excessive smartphone use.
  • It is suitable for use with adolescents and young adults.
  • The MUST can aid in early identification and intervention for problematic smartphone use.
