title: Stage Validity of the Health Action Process Approach in African American Breast Cancer Survivors.
abstract: The Health Action Process Approach (HAPA) has been applied in a number of populations because it proposes to overcome limitations from previous health behavior theories. However, it has yet to be applied to cancer survivors or racial/ethnic minorities. In this study, we examined the construct validity of the HAPA phase and stage algorithms in a sample of African American breast cancer survivors. A total of 259 African American breast cancer survivors (mean age = 54 years) participated in a Web-based survey that assessed sociodemographic and medical characteristics, physical activity, and HAPA constructs. Analysis of covariance was used to compare mean differences between HAPA phase/stage. Statistical significance was determined at p < 0.017 due to multiple comparisons. Phase and stage inconsistencies were observed for most constructs. However, adequate distinctions were made for motivational self-efficacy and intentions (i.e., P = I < A) by phase, and both action and coping planning (i.e., P < I < A) by stage. Our data indicate partial support of the HAPA algorithm to classify African American breast cancer survivors according to stage or phase. Modifying the staging algorithm or constructs are needed if stage- or phase-based interventions can be designed for this population.
