Introduction
Gottfredson and Hirschi’s general theory of crime (1990)
Proposes that low self-control is the main cause of crime and related behaviors.
Lacks empirical work examining factors that give rise to low self-control.
Parental Influence
Gottfredson and Hirschi suggest parents are the sole factors in fostering or thwarting low self-control.
Disregard for genetic influences on self-control.
Genetic Research
ADHD and frontostriatal system deficits show high heritability.
Research aims to determine if "parents matter" in creating low self-control after considering genetic factors.
Sample Population: Twin children were studied to evaluate parenting measures and their effect on self-control.
Literature Review
Strength of Gottfredson and Hirschi’s Theory
Supported by meta-analytic review by Pratt and Cullen (2000).
Low self-control is a predictor of criminal behavior across various samples.
Theory continues to influence criminological discourse (Geis, 2000; Marcus, 2004; Sampson and Laub, 1995).
Parental Impact on Self-Control Development
Study connections between effective parenting behaviors and low self-control in children.
Effective monitoring = higher self-control; ineffective = lower self-control.
Empirical Evidence
Limited studies supporting parenting influence.
Previous findings link effective child-rearing to self-control (Cochran et al., 1998).
Studies consistently attribute low self-control to proper parenting practices.
Genetic Considerations in Self-Control
Critique of Gottfredson and Hirschi's Stance
Argued that genetic factors contribute significantly to traits related to low self-control (Price et al., 2001; Rietveld et al., 2003).
ADHD heritability = 75% (Spencer et al., 2002).
Barkley (2005): ADHD 97% heritable, suggesting genetics overpower environmental factors.
Harris’s Perspective
Challenges the idea that parenting significantly influences personality traits.
Varied parenting environments lead to inconsistency in child outcomes (Harris, 1998).
Parenting practices can appear significant due to shared genetic influences.
Research Design and Methodology
Two-Part Focus
Assess parenting effects on self-control in children using a national dataset (mother/teacher reports).
Utilize twin samples to address genetic variability.
Sample Details
Data sourced from: Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K).
Study size: over 21,000 children, with specific focus on 1,000 randomly selected samples.
Unique feature: capability to control for shared genetic variance among twins.
Variables and Measures
Low Self-Control Measurement
Utilized Gresham and Elliott’s Social Skills Rating Scale (SSRS).
Reliable metrics for parental and teacher assessments of self-control and impulsivity.
Parenting Measures
Five main scales assessed:
Parental Involvement (time spent on activities with child).
Parental Withdrawal (emotional distance from child).
Parental Affection (warmth and closeness).
Physical Punishment (disciplinary measures).
Family Rules (structure of parenting dynamics regarding media consumption).
Statistical Analysis
Compared Ordinary Least Squares (OLS) regression models with Hierarchical Linear Models (HLM) to account for genetic clustering.
OLS models: higher significance in parenting measures.
HLM models: reduced significance for parenting measures when clustering accounted.
Results
Parenting Effects in Kindergarten
Findings From OLS Regression
Significant factors influencing low self-control included:
Parental withdrawal (positive correlation).
Parental affection and family rules (negative correlation).
Control factors: gender, academic preparedness, neighborhood disadvantage.
Findings From HLM Analysis
Consistent with critiques suggesting overestimation in OLS models.
Only parental withdrawal and affection remained statistically significant after controlling for genetics.
Teacher-reported measures had differences revealing fewer parenting significance effects.
Parenting Effects in First Grade
OLS Findings
Similar to kindergarten results, with parental withdrawal retaining significance.
Gender and academic preparedness again proved significant.
HLM Analysis Results
Only parental withdrawal and academic preparedness remained significant, indicating overestimation in parent-reported data.
Discussion
The findings question the weight of parenting’s impact on self-control relative to genetic influences.
Parenting variables influence diminished significantly when genetic similarities emerged.
Suggests that external environmental factors, habitual interaction, and genetic predispositions combine complexly to determine self-control in children.
Conclusions
Parenting practices, when assessed in isolation, show an association with low self-control but may not be as impactful when factoring genetics.
Need for further research to understand the dynamics between parental socialization, genetic heritability, and behavioral outcomes.
