Romm, Madeline CarlyleThoughtfully reflective decision-making (TRDM) is a type of decision-making associated with favorable life outcomes. TRDM varies between and within individuals and, although there is evidence that TRDM is associated with beneficial choices, little research to date has examined the relationship between gender and TRDM. Using the AddHealth (public) data, this thesis investigates (1) whether TRDM is gendered; (2) how TRDM is related to delinquency; (3) whether the effect of TRDM on delinquency is moderated by gender and/or affected by offense type? Analyses reveal that particular components of TRDM are gendered and those components are related to delinquency participation. Further, although results show that utilization of TRDM is significantly different for males and females and TRDM generally is associated with a lower risk of minor delinquency involvement, neither gender nor gender*age moderates the TRDM-delinquency relationship. I thus conclude that TRDM is not a sufficient explanation for the gender gap in crime.enThesisCriminology
