This study discusses methodological considerations in assessing paternal identity with scale versus pie chart measures as they relate to paternal involvement. Additionally, it compares data on paternal identity and behavior at the role level (father) versus the domain level (more specific aspects of fathering, such as caregiving). Results indicate that pie chart and scale measures of identity both are positively correlated with measures of involvement. Further, domain-level measures of identity are more frequently correlated with measures of involvement than role-level measures of identity are. Findings suggest that domain-level pie chart measures of identity may be a viable alternative to scale measures of identity. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
