Child maltreatment, alexithymia, and problematic internet use in young adulthood

The goals of this study were to (a) examine the phenomenology and developmental correlates of problematic Internet use (PIU) in a large and diverse college student sample; (b) evaluate a developmental process model of PIU in which the expected association between child maltreatment and PIU would be explained by alexithymia; and (c) explore these relations as a function of gender and race. PIU was assessed in a sample of 1,470 college students (62.9 percent female, 37.1 percent male; M(age)=19.13 years [SD=1.49]; 46.1 percent Asian, 28.2 percent Hispanic, 16.3 percent White, 5.9 percent Black, and 3.5 percent Multiracial/Other) who participated in a larger study of young adult adaptation, which included measures of child maltreatment, alexithymia, self-concept, social support, and psychopathology. Males and Asian students endorsed higher levels of PIU than females and other ethnoracial groups, respectively. PIU was related to contemporaneous maladaptation in the form of decreased self-concept, lower social support, and increased psychopathology across groups. Experiences of child maltreatment were related to increased PIU, and mediation analyses showed that this relation was partially explained by alexithymia. These relations were comparable across males and females and between Asian and non-Asian respondents. The analyses provide evidence for the significant role of child maltreatment and the cognitive-affective deficits it precipitates in understanding pathways toward PIU in young adulthood. Our findings suggest that maltreated youth are at disproportionate risk for PIU, and their capacities to regulate and process emotion are important targets for prevention and therapeutic intervention.
