Objective: to determine the relationship between bounding attachment and the incidence of postpartum blues in patients after caesarean section surgery at RSIA AMC Metro City. Method: Quantitative research type, cross sectional method. Sample of 75 respondents, purposive sampling technique, data collection tool, Edinburgh Postnatal Depression Scale questionnaire & bounding attachment observation. Chi Square test analysis. Results: Post partum mothers who did not do good bonding attachment experienced post partum blues as many as 37 (88.1%), mothers who did good bonding attachment experienced postpartum blues as many as 3 respondents (9.1%). The results of the chi square test obtained a p-value = 0.000, so it was found that bounding attachment had a significant relationship with the incidence of postpartum blues in patients after caesarean section surgery. OR = 74,000, meaning that mothers who are not good at bonding attachment have a 74 has risk of experiencing postpartum blues.

Tujuan: untuk mengetahui hubungan bounding attachment dengan kejadian posartum blues pada pasien pasca operasi sectio caesarea di RSIA AMC Kota Metro. Metode: Jenis penelitian kuantitaif, metode cross sectional. Sampel 75 responden, teknik purposive sampling, Alat pengumpulan data kuesioner Edinburg Postnatal Depression Scale & observasi bounding attachment. analisis uji Chi Square. Hasil: Ibu post partum yang tidak baik melakukan bounding attachment mengalami post partum blues sebanyak 37 (88,1%), Ibu yang melakukan bounding attachment yang baik mengalami postpartum blues sebanyak 3 responden (9,1%) . Hasil uji chi square diperoleh nilai p-value = 0,000, sehingga didapat bounding attachment memiliki hubungan signifikan terhadap kejadian postpartum blues pada pasien pasca operasi sectio caesarea. OR = 74.000, artinya Ibu yang tidak baik melakukan bounding attachment berisiko 74 kali mengalami postpartum blues Kesimpulan: Terdapat hubungan antara bounding attachment ibu post partum SC dengan terjadinya post partum blues.
