This study aimed to develop and validate The Cancer Family Impact Scale (CFIS), an instrument for use in studies investigating relationships among family factors and colorectal cancer (CRC) screening when family history is a risk factor. We used existing data to develop the measure from 1,285 participants (637 families) across the United States who were in the Johns Hopkins Colon Cancer Genetic Testing study. Participants were 94% white with an average age of 50.1 years, and 60% were women. None had a personal CRC history, and eighty percent had 1 FDR with CRC and 20% had more than one FDR with CRC. The study had three aims: (1) to identify the latent factors underlying the CFIS via exploratory factor analysis (EFA); (2) to confirm the findings of the EFA via confirmatory factor analysis (CFA); and (3) to assess the reliability of the scale via Cronbach's alpha. Exploratory analyses were performed on a split half of the sample, and the final model was confirmed on the other half. The EFA suggested the CFIS was an 18-item measure with 5 latent constructs: (1) NEGATIVE: negative effects of cancer on the family; (2) POSITIVE: positive effects of cancer on the family; (3) COMMUNICATE: how families communicate about cancer; (4) FLOW: how information about cancer is conveyed in families; and (5) NORM: how individuals react to family norms about cancer. CFA on the holdout sample showed the CFIS to have a reasonably good fit (Chi-square = 389.977, df = 122, RMSEA= 0.058 (.052-.065), CFI=.902, TLI=.877, GF1=.939). The overall reliability of the scale was α=0.65. The reliability of the subscales was: (1) NEGATIVE α = 0.682; (2) POSITIVE α = 0.686; (3) COMMUNICATE α = 0.723; (4) FLOW α = 0.467; and (5) NORM α = 0.732. ^ We concluded the CFIS to be a good measure with most fit levels over 0.90. The CFIS could be used to compare theoretically driven hypotheses about the pathways through which family factors could influence health behavior among unaffected individuals at risk due to family history, and also aid in the development and evaluation of cancer prevention interventions including a family component. ^

An earlier version of this manuscript was prepared for the Chapin Hall invitational seminar on family preservation, The Chapin Hall Center for Children at the University of Chicago, September 16 & 17, 1999. The author wishes to acknowledge the comments and helpful suggestions of seminar participants-Jacqueline McCroskey, Martha Shirk, Fran Jacobs, John Schuerman, Lee Schorr, Charlotte Booth, Kristi Nelson, Susan Kelly, Frank Farrow, and Susan Notkin. These comments, as indeed many of their prior contributions, have had a seminal effect on my thinking about family preservation services over the years. Clark Peters and other Chapin Hall staff deserve special thanks for creating the conditions necessary to produce a lively and productive discussion. As always, Harold Richman, Executive Director of Chapin Hall, and Hermon Dunlap, Smith Professor at the School of Social Service Administration of the University of Chicago, as seminar convenor combined perfectly the skills of gracious host and incisive critic. We in the child welfare field are in his debt for continually raising the level of discourse in our field. In the end, as it should be, the thoughts and opinions in the following paper are wholly my own.
