All the variables reported are from KA women, but socio-demographic variables are from both KA women and their husbands. Mammography uptake was measured by self-report at 6- months and 15-months post-baseline, based on the ACS guideline recommending that women 40 and older receive a mammogram every year. Predictor variables measured were age, education, employment, and level of acculturation. Level of acculturation was measured by the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA). The SL-ASIA was modified slightly by deleting one item about generation because it was not relevant for first-generation KAs. The words "Asian" and "Oriental" in the original instrument were also changed to "Korean." Scoring for the revised SL-ASIA was the same as the original SL-ASIA, using a 5-point Likert scale with a final score ranging from 1.00 (low acculturation) to 5.00 (high acculturation). Questions on health care resources and utilization, health insurance status, usual source of care (a regular place or doctor to visit), and physical examinations in the past 2 years without sickness or for health problems were measured. Family history of breast cancer and history of mammography (when the last mammogram was, if they ever had one) were also measured.
