Pre-session data collection

All students studying in grades eighth, nineth, and tenth standards were approached for the study. Before a briefing session on responsible smartphone and social media use, data were collected using anonymous survey. Data collection form consisted of (a) sociodemographic information like age, gender, class in school, current living condition, (b) pattern of smartphone use and smartphone addiction scale-short version (SAS-SV), and (c) pattern of social media use and social media disorder (SMD) scale were used.[10,11]

SAS-SV has been developed and validated in South Korea.[10] In Indian setting, it has been used in a study on problematic use of smartphone amongst medical students by Basu et al.[12] It has ten-items rated on a Likert scale from strongly agree to strongly disagree. It has a sensitivity value of 0.867 and specificity value of 0.893 in boys, and sensitivity value of 0.875 and a specificity value of 0.886 in girls. It has been found to be reliable and valid measure of smartphone addiction.[10]

SMD scale has been developed in Dutch population. It has nine yes-no questions to be rated keeping the last one year in mind. It was found to be a psychometrically sound and valid instrument. As per DSM-5 definition, diagnosis of IGD is made if the person meet five (or more) of the nine criteria during 12 months.[3] Same criteria have been used earlier to define SMD.[11]
