SMU AND WELLBEING ACROSS COUNTRIES 119 4 association was ( B = 2.839, p = 0.011; Figure 4.3B), which explained 33.3% of the country-variance in this association. The country-level prevalence of intense SMU did not explain any country-variance in this association. Cross-National Differences in the Prevalence of Intense and Problematic Social Media Use Table 4.3 shows that the prevalence of intense SMU varied from 17.35% (Switzerland) to 49.87% (Italy), while the prevalence of problematic SMU varied from 3.22% (the Netherlands) to 14.17% (Spain). Costs of mobile broadband and internet speed did not explain these differences in the country-level prevalence of intense SMU ( B < 0.001, p = 0.628; B = -0.005, p = 0.254) and problematic SMU ( B = < 0.001, p = 0.568; B = -0.001, p = 0.338).
