Prospective study of the association between neurobehavior disinhibition and peer environment on illegal drug use in boys and girls.

Background: Individual and contextual factors jointly participate in the onset and progression of substance abuse; however, the pattern of their relationship in males and females has not been systematically studied.

Objectives: Male and female children and adolescents were compared to determine the relative influence of individual susceptibility (neurobehavior disinhibition or ND) and social environment (deviancy in peers) on use of illegal drugs.

Methods: Boys (N = 380) and girls (N = 127) were prospectively tracked from age 10-12 to age 16 to delineate the role of ND and peer deviancy on use of illegal drugs.

Assessment of risk for substance use disorder consequent to consumption of illegal drugs: psychometric validation of the neurobehavior disinhibition trait.

Previous research has shown that the trait neurobehavior disinhibition (ND), which consists of affect, behavior, and cognitive indicators of self-regulation, is a significant predictor of substance use disorder (SUD) between childhood and young adulthood. The authors evaluated the psychometric properties of the ND trait in 278 boys evaluated at ages 10-12 and 16 years. ND score significantly predicted SUD and outcomes that commonly manifest in tandem with SUD by age 19, such as violence, arrests, committing crime while intoxicated, and concussion injury.

Reciprocal influence of parent discipline and child's behavior on risk for substance use disorder: a nine-year prospective study.

Aim: This study aimed at determining the association of father's and mother's (parental) substance use disorder (SUD) and discipline styles and son's neurobehavior disinhibition (ND) with son's SUD from childhood (age 10-12) to young adulthood (age 19). It was hypothesized that (1) parental discipline styles and son's ND mediate the association between parental SUD and son's SUD, (2) son's ND mediates the association between parental discipline styles and son's SUD, and (3) parental discipline styles mediate the association between ND and SUD in the son.

Methods: Two-hundred-sixty-three families including a 10-12 year-old son and both parents participated in the study.

Child neglect and oral health problems in offspring of substance-abusing fathers.

This study examined (1) orodental (OD) problems in 10-19-year-old children of substance use disorder (SUD) (n = 127) and non-SUD fathers (n = 111) and (2) the moderating effect of child's substance use (SU) involvement in the associations of paternal SUD and neglectful parenting with OD problems in the offspring. The results showed that periodontal problems differentiated between groups and the interactions between child's SU involvement and paternal SUD and neglectful parenting were respectively associated with hard/soft tissue lesions and carious lesions in the offspring, indicating that SU involvement increases risk for OD due to paternal SUD and neglectful parenting.

Executive functioning, temperament, and drug use involvement in adolescent females with a substance use disorder.

Background: This study determined whether temperament mediates the relation between executive functioning (EF) and drug use involvement and whether EF and temperament interact to account for unique variance in drug use involvement.

Method: Participants were 340, 14-18-year-old, adolescent females with a substance use disorder and controls. EF was measured using a battery of neuropsychological tests, temperament was assessed using the Dimensions of Temperament Survey--Revised, and drug use involvement was measured with the Drug Use Screening Inventory.

Origins and consequences of child neglect in substance abuse families.

The empirical literature pertaining to the prevalence, origins, and consequences of neglectful parenting as it relates to substance abuse is critically reviewed. Available evidence indicates that children who experience parental neglect, with or without parental alcohol or drug abuse, are at high risk for substance use disorder (SUD). The effects of parental substance abuse on substance abuse outcome of their children appear to be partly mediated by their neglectful parenting.
