Abstract
The relation between early mother-infant interaction and later socio-emotional development has been well established. The present study addresses the more recent interest in the impact of maternal caregiving on cognitive development and their role in decision-making in young adulthood. Using data from a prospective longitudinal study on attachment, prediction from early mother-infant interactions at age 18 months and from verbal and nonverbal cognitive skill at age 5 were examined as predictors of a substance use disorder (abuse/dependence) in young adulthood (age 20) on the Structured Clinical Interview for DSM-IV (SCID). Results reveal that the mother's withdrawal from interaction with the infant at age 18 months, coded using the AMBIANCE coding system (Atypical Maternal Behavior Instrument for Assessment and Classification), was associated with the child's lower nonverbal cognitive scores but not verbal cognitive scores at age 5. In addition, maternal withdrawal at 18 months predicted a clinical diagnosis of substance use disorder (alcohol/cannabis) at age 20. Finally, nonverbal reasoning at age 5 mediated the relationship between early maternal withdrawal and substance use disorder (alcohol/cannabis) in young adulthood. Findings indicate the need for further work examining how early maternal withdrawal affects nonverbal cognitive development by school entry, and how these nonverbal deficits further contribute to maladaptive coping strategies such as substance use by young adulthood.

The relation between early mother–infant interaction and later socio-emotional development has been well established
The present study addressed these gaps by examining the impact of a specific type of disrupted early caregiving, maternal withdrawal, on the development of verbal and nonverbal cognitive skills at age 5, as well as on Axis I substance use disorder (SUD) diagnoses assessed using the Structured Clinical
SUD involving illicit substances other than alcohol and cannabis was associated with higher maternal withdrawal (r = .42, p < .05), only a small number of participants qualified for a SUD involving these substances (14.3%, N = 5) so these results were not further followed up
Summary
The relation between early mother–infant interaction and later socio-emotional development has been well established. Using data from a prospective longitudinal study on attachment, prediction from early mother–infant interactions at age 18 months and from verbal and nonverbal cognitive skill at age 5 were examined as predictors of a substance use disorder (abuse/dependence) in young adulthood (age 20) on the Structured Clinical Interview for DSM-IV (SCID). Results reveal that the mother’s withdrawal from interaction with the infant at age 18 months, coded using the AMBIANCE coding system (Atypical Maternal Behavior Instrument for Assessment and Classification), was associated with the child’s lower nonverbal cognitive scores but not verbal cognitive scores at age 5. Nonverbal reasoning at age 5 mediated the relationship between early maternal withdrawal and substance use disorder (alcohol/cannabis) in young adulthood. Findings indicate the need for further work examining how early maternal withdrawal affects nonverbal cognitive development by school entry, and how these nonverbal deficits further contribute to maladaptive coping strategies such as substance use by young adulthood. In addition to child behavioral problems, disruptions in the mother–infant attachment relationship have been shown to influence cognitive development
