<p>This study explores patterns of internet combination use based on diverse combined needs and their impact on problem behaviors after one year. A total of 7,882 Chinese college students (35.2% male) reported their internet use and problem behaviors in two waves. Five patterns of internet combination use were identified through latent profile analysis: low-intensity use (8.79%), high-intensity social media use (7.17%), moderate-intensity use (36.37%), low-intensity online games use (21.4%), and high-intensity use (26.27%). Among these, moderate-intensity and high-intensity users were more prevalent among college students. Higher levels of internalizing and externalizing problem behaviors were observed in patterns of high-intensity use, low-intensity online games use, and moderate-intensity use. These findings highlight the heterogeneity of internet combination use that varies according to internet use needs, and the relationships between different patterns of internet combination use and problem behaviors one year later. Early identification of patterns of internet combination use could be a crucial component of effective strategies to prevent problem behaviors in college students. It is beneficial to understanding their purposes or needs of internet use and helping them effectively identifing the risks of certain internet use patterns, rather than merely focusing on the duration of online engagement.</p>
