Validation of the Brief Addiction to Smartphone Scale (BASS) and the Hungarian Smartphone Deprivation Inventory (HSDI) in adult sample

: Problematic smartphone use became noteworthy, since these devices, besides their undeniable utility, also carry the risk of excessive usage, proving an adverse effect on health, performance and social relationships. The study aims to analyze and validate the psychometric indicators of the Brief Addiction to Smartphone Scale (BASS) and Hungarian Smartphone Deprivation Inventory (HSDI) among the 442 adult participants. The factorial structure of the two scales was assessed through explorative factor analysis. Both scales showed a one-factor structure; the BASS accounted for 35% of the variance, and the nine items of HSDI accounted for 59% of the variance. The degree of smartphone usage and the occurrence of the symptoms of withdrawal showed a significant correlation with age, but gender differences were not detectable. The two scales proved to be reliable tools in the screening of problematic smartphone use among adults.
