|---|---|---|---|---|---|
| Atroszko et al. (2018) | Poland | Cross-sectional | N = 1157 undergraduates (F = 51.9%) Age = 20.33 (1.68) |
Bivariate correlation Positive association between GN and FB problematic use (r = 0.13, p < 0.01) Multiple regression analysis GN was a significant positive predictor of BFAS total score after controlling for the Big Five Personality traits (β = 0.17, p < 0.01) |

| Blachnio and Przepiórka (2018) | Poland | Cross-sectional | N = 360 undergraduates (F = 64%) Age = 22.22 (SD = 6.84) |
Bivariate correlation Positive association between GN and FB intrusion (r = 0.32, p < 0.01). Structural Equation Modeling A positive significant path between GN and FB intrusion was found |

| Brailovskaia and Margraf (2017) | Germany | Longitudinal | N = 179 undergraduates (F = 77.1%) Age = 22.52 (5.00) |
Bivariate correlation GN at T1 was significantly and positively associated with FB addiction one year later (r = 0.19, p < .05). Multiple Regression analysis Controlling for gender and age, narcissism explained 7.1% of the variance in FB addiction scores (β = 0.26, p < .001) |

| Brailovskaia, Schillack, and Margraf (2018) | Germany | Cross-sectional | N = 520 undergraduates (F = 75%) Age = 22.42 (4.61) |
Multiple Regression Analysis GN predicted BFAS total score (β = 0.136, p < .001) |

| Brailovskaia et al. (2019) | Germany | Cross-sectional | N = 112 inpatients with psychological problems (F = 71.4%) Age = 49.43 (9.17) |
Bivariate correlation Significant positive association between GN and BFAS total score (r = 0.21, p < .05) |

| Casale and Fioravanti (2018) | Italy | Cross-sectional | N = 535 undergraduates (F = 50.08%) Age = 22.70 (2.76) |
Bivariate correlation Positive association between both GN and VN and FB problematic use (r = 0.13 and r = 0.25, p < .001, respectively) Structural Equation Modeling GN was indirectly associated with FB addiction via the need to belong and the need for admiration |
