The participants' internet use was labelled pathological, risky, or non-problematic following a diagnostic interview. Those with more severe problematic internet use reported worse moods, greater stress, longer usage times, and more neglect of other parts of their lives. The strongest predictor of whether someone would engage in their designated activity on a given day wasn't stress or mood but temptation. The latest study found that days involving stronger temptation also brought more time online, more pleasure and relief, and more neglect. The observational study found associations and can't establish whether problematic internet use directly caused the worse mood or stress.
