The aim of this study was to explore the relation between Problematic Gaming Behaviour (PGB) and specific psychological factors (gaming motives, self-awareness of problematic gaming behaviour) and structural factors (game genres) among Finnish adolescents and young adults. A national survey of 271 respondents, aged 13 to 24, participated in the study. The study sample was randomly selected from the Population Register Center. Multiple regression analysis was used as a means of examining links between game genres, gaming motives and PGB. In addition, pairwise comparisons of a non-problematic gaming behavior group and a problematic gaming behavior group were used as a means of examining differences across game genre use and self-awareness of PGB. PGB was particularly associated with the use of a group of games encompassing role-playing, progression (e.g., character development), action and strategy features. The findings indicated that entertainment-achievement, social and escapism motives were associated with PGB. On the whole, this study emphasized that specific game genres and playing motives are involved in problematic use of digital game playing.
