Given the detrimental effects associated with problematic internet use (PIU) and the need to better understand its nature and evolution, the present study examined the development of PIU in a sample of 1,750 adolescents (aged 16-19) from Finland over a 3-year period. We documented the social (loneliness, perceived maternal and paternal behaviors) and individual (sex) antecedents, as well as the outcome implications (depressive symptoms, substance use, academic achievement) of PIU trajectories. Outcomes also predicted PIU trajectories. Latent curve modeling revealed an initially moderate, and subsequently decreasing trajectory of PIU. PIU was predicted by loneliness, paternal neglect, maternal care, depressive symptoms, and being male. In turn, PIU trajectories predicted increases in depressive symptoms and substance use, but decreases in academic achievement.
鉴于与问题性互联网使用（PIU）相关的有害影响，以及需要更好地理解其性质和演变，本研究在芬兰对 1750 名青少年（年龄在 16-19 岁）进行了为期 3 年的研究，以考察 PIU 的发展。我们记录了 PIU 轨迹的社会（孤独感、感知到的母亲和父亲的行为）和个体（性别）前因，以及结果的影响（抑郁症状、物质使用、学业成绩）。结果也预测了 PIU 轨迹。潜在曲线建模显示 PIU 最初呈中等程度，随后呈下降趋势。孤独感、父忽视、母关爱、抑郁症状和男性预测 PIU。反过来，PIU 轨迹预测抑郁症状和物质使用的增加，但学业成绩的下降。
