A qualitative codebook developed from n = 85 U.S. Latino/Hispanic first-time fathers of 18-month old children participating in the Baby Books 2 parenting intervention. During a home visit, fathers were asked the question: "What makes you want to be a good parent?" and responses were video-recorded and transcribed by Spanish-English bilingual research assistants. A team of five researchers used thematic analysis to analyze the transcript data and produce the codebook, capturing emergent themes and subthemes regarding fathers' motivations to be good parents.
