Rates of adolescent mood disorders and adolescent smartphone use have risen in parallel, leading some to suggest that smartphone use might have detrimental effects on adolescents' moods. Alternatively, it is possible that adolescents turn to smartphone use when experiencing negative mood. Past experimental study suggests that certain smartphone activities can reduce adolescents' negative moods or induce more positive moods, but little is known about the effects of real-world smartphone use, which can involve many different activities. A sample of N = 253 adolescents participated in an Ecological Momentary Assessment (EMA) procedure, which assessed which smartphone activities they were engaged in at random moments throughout the day. This procedure also prompted adolescents to rate their moods before and during smartphone use. Adolescents reported mood improvements during almost all smartphone activities and did not report that moods became more negative during any smartphone activity. Mood improvements were the largest when adolescents said they were listening to music, podcasts, or audiobooks. This may suggest some adolescent smartphone use is driven by a desire to alleviate negative mood.
