Improving Family History Collection

Family history is important for assessing risk of cancer. This study aimed to improve cancer family history communication and collection by training and motivating lay individuals to construct pedigrees. The authors' ultimate goal is to improve identification of familial cancer. Participants (n = 200) completed preintervention, postintervention, and 1-week follow-up surveys to assess pedigree construction. The intervention reviewed basic construction and interpretation of a pedigree for familial cancer. As a result of intervention, individuals reported more positive attitudes about collecting family history, were more likely to intend to speak to family and physicians about cancer risk, better understood a sample pedigree, and constructed more detailed pedigrees of their family history. At follow-up, 25% of the sample had spoken with their families about cancer risk. For those individuals who had not spoken with family, higher postintervention pedigree knowledge was associated with greater intentions to speak with family in the future. The intervention improved the communication and collection of pedigrees and communication about cancer risk, which could be used to improve the identification of individuals with familial cancers and awareness of family cancer risk.
