Mobile phone addiction is a type of technological addiction or nonsubstance addiction. The present study was conducted with the objectives of developing and validating a mobile phone addiction scale in medical students and to assess the burden and factors associated with mobile phone addiction-like behavior.
Materials and Methods:
A cross-sectional study was conducted among undergraduate medical students aged ≥18 years studying in a medical college in New Delhi, India from December 2016 to May 2017. A pretested self-administered questionnaire was used for data collection. Mobile phone addiction was assessed using a self-designed 20-item Mobile Phone Addiction Scale (MPAS). Data were analyzed using IBM SPSS Version 17.
The study comprised of 233 (60.1%) male and 155 (39.9%) female medical students with a mean age of 20.48 years. MPAS had a high level of internal consistency (Cronbach’s alpha 0.90). Bartlett’s test of sphericity was statistically significant (P < 0.0001), indicating that the MPAS data were likely factorizable. A principal component analysis found strong loadings on items relating to four components: harmful use, intense desire, impaired control, and tolerance. A subsequent two-stage cluster analysis of all the 20-items of the MPAS classified 155 (39.9%) students with mobile phone addiction-like behavior that was lower in adolescent compared to older students, but there was no significant difference across gender.
Mobile phone use with increasing adoption of smartphones promotes an addiction-like behavior that is evolving as a public health problem in a large proportion of Indian youth.
