investigate the moderating role of mobile phone dependency in the model of predicting subjective vitality based on perceived social support and Alexithymia mediated by academic procrastination

The purpose of this study was to investigate the moderating role of mobile phone dependency in the model of predicting subjective vitality based on perceived social support and alexithymia mediated by academic procrastination in adolescent girls.

The statistical population included the Bandar Imam Khomeini high school girl students, in 2019. 352 of them were selected by multistage cluster random sampling. They responded to these questionnaires: smartphone addiction scale, Multidimensional Scale of Perceived Social Support, Alexithymia Questionnaire, academic procrastination Scale, and subjective vitality questionnaire. Data were analyzed by structural equation modeling

The results showed that in both groups of addicted students to mobile and non-mobile addicted, the direct path of social support and alexithymia was not significant with subjective vitality, but the direct path of academic procrastination to subjective vitality was negative and significant and social support had a negative and significant relationship with academic procrastination and alexithymia had a positive and significant relationship with academic procrastination. Academic procrastination also mediated the relationship between social support and alexithymia with subjective vitality. Dependence on mobile phones moderated this mediation model.

By increasing social support and treating alexithymia, it is possible to reduce academic procrastination in adolescents and thereby improve subjective vitality. And by teaching the correct use of mobile phones, the intensity of the impact of factors on reducing subjective vitality decreased.
