In order to explore the relationship between mobile phone dependency and social self-efficacy and
reveal the mechanism of shy between them, 221 college students were investigated by questionnaire. Results:
Social self-efficacy and shy, mobile phone dependency are significantly negatively correlated, shy and mobile
phone dependency are significantly positively correlated; mobile phone dependency and shy negatively predict
social self-efficacy; shy plays a partial mediating role between mobile phone dependency and social self-efficacy.
Conclusion: Mobile phone dependency and shy are important predictors of social self-efficacy. The effect of
mobile phone dependency on social self-efficacy is partially through shy. The proportion of indirect effect to
total effect was 56.0%. Individuals could control mobile phone dependence to reduce the level of shy, and then
improve their social self-efficacy.
