"One in five teens say that Instagram makes them feel worse about themselves, with UK girls the most negative" Stated effect of Instagram, as the chart prints it (Much worse / Somewhat worse / No effect / Somewhat better / Much better): US Total 3% / 16% / 41% / 29% / 12%; US Boys 2% / 12% / 37% / 32% / 18%; US Girls 3% / 18% / 43% / 29% / 8%; UK Total 2% / 19% / 46% / 28% / 5%; UK Boys 1% / 13% / 50% / 31% / 5%; UK Girls 2% / 23% / 44% / 26% / 4%. Much worse and Somewhat worse combined, which is the figure this card's title rests on and is the archive's own arithmetic rather than anything printed on the slide: 19% (US Total), 14% (US Boys), 21% (US Girls), 21% (UK Total), 14% (UK Boys), 25% (UK Girls). "Q: In general, how has Instagram affected [the way you feel about yourself/your mental health]? There were no statistically significant differences among those who answered for 'the way you feel about yourself' and those who answered for 'your mental health' US n = 1296; UK n = 1308"
