There was over 79% agreement between interview scores and questionnaire scores for each dimension. Construct validity was confirmed by showing that subscale scores varied in predicted ways. For women who were recalled for further investigation, scores on each subscale measuring negative consequences, were higher at the recall clinic that at screening clinic (emotional: t=-7.28; df=70; P
