Measurement of variables in one moment does not mean that all objects are observed exactly at the same time, but it means that each subject is observed only once and the measurement of the subject variable is performed during the examination. The results of research based on chi square test showed a significant influence that is attitude ρ = 0,18 where ρ > α (0,05) so that H0 accepted mean no attitude influence. The subjective norm ρ = 0.35> ρ > α (0,05) so that H0 is accepted which means there is no influence between subjective norms. Ability to control ρ = 0.12 > ρ > α (0,05) so that H0 is accepted which means there is no influence between the perception of control ability. Interest ρ = 0.96 > ρ > α (0.05) so that H0 is accepted which means there is no influence of interest. The most dominant fator is the education level, p = 0.03 > p < α (0.05) so that H0 is rejected which means there is an influence between the level of education in behavior on postpartum care at Rumah Sakit Ibu Anak Fauziah Tulungagung.
