Does the apple fall far from the tree? when parenting styles disrupt the intergenerational pattern of substance use

Area of Science:

• Psychology
• Public Health
• Sociology

Background:

• Intergenerational transmission of substance use is a significant public health concern.
• Parenting styles are hypothesized to influence adolescent substance use behaviors.
• Understanding protective factors is crucial for developing effective interventions.

Purpose of the Study:

• To investigate the role of parenting styles in buffering the intergenerational transmission of substance use.
• To identify specific parenting styles that may protect adolescents from substance use.
• To examine the association between parental and adolescent substance use profiles.

Main Methods:

• Utilized a person-centered analytic strategy with 4,280 adolescent-parent dyads in Brazil.
• Employed Latent Class Analysis to identify substance use profiles across generations.
• Applied Latent Transition Analysis to model the association between these profiles.

Main Results:

• Parental and adolescent substance use profiles showed strong alignment, particularly among abstainers.
• Authoritative parenting significantly decreased adolescents' likelihood of polysubstance use, even with high-risk parents.
• Authoritarian parenting reduced overall risk but increased alcohol-specific transmission; permissive and neglectful styles offered no protection.

Conclusions:

• Parenting style plays a critical role in modulating intergenerational substance use.
• Authoritative parenting emerges as a key protective factor against adolescent polysubstance use.
• Family-based interventions focusing on authoritative parenting strategies can disrupt intergenerational substance use patterns.
