| Abstract: | Individuals with a history of childhood abuse (CA, including neglect and abuse by caregivers before the age of 18 years) have more severe substance dependence problems than those without a history of childhood abuse. However, whether a history of CA exacerbates craving and the mechanism of this effect remain largely unknown. The aim of this study was to explore the role of alexithymia in the effects of CA on craving in a large sample of methamphetamine-dependent individuals based on latent vulnerability theory. A total of 324 methamphetamine-dependent individuals who met DSM-5 criteria for substance use disorder were recruited. CA, alexithymia, and craving data were collected from the Childhood Trauma Questionnaire, the Toronto Alexithymia Scale-20, and the Obsessive Compulsive Drug Use Scale, respectively. t tests and ANCOVA were conducted to compare variables between the CA and non-CA groups, while partial correlation and mediation analyses were conducted to examine the potential mediating role of alexithymia in the relationship between CA and craving. Abused methamphetamine-dependent individuals reported higher levels of craving and higher levels of alexithymia than those of non-abused methamphetamine-dependent individuals. Alexithymia partially mediated the link between CA and craving, especially the effect of CA on craving frequency was fully mediated by alexithymia. Our findings reveal that a history of childhood abuse has a lasting effect on craving in stimulant-dependent individuals, and alexithymia contributes to some extent to the severity of substance abuse problems in abused methamphetamine-dependent individuals.
