“…Although the option of creating separate cut scores by gender was considered, it was ultimately decided against doing so because of the absence of a gender effect for the clinical sample, the small effect size observed in the non-clinical sample, and previous research that suggests that externalizing profiles in preschoolers do not substantially vary across gender. Longitudinal research has found that the trajectory for externalizing behaviors for males and females are similar in preschool aged children (Beyer, Postert, Muller, Furniss, 2012;Hill, Degan, Calkins, and Keane, 2006). For example, Hill, Degan, Calkins, and Keane (2006) found that although reasons for membership in externalizing groups were different across genders, the trend in the developmental course across genders for preschool aged children was markedly similar.…”
