[ABSTRAK
Tindakan invasif yang didapat anak selama dirawat menimbulkan reaksi nyeri.Perawat perlu mengetahui faktor-faktor yang berhubungan dengan reaksi nyeri.Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang berhubungandengan reaksi nyeri akibat tindakan invasif. Desain penelitian adalah penelitianobservasional dengan pendekatan cross sectional dengan teknik pengambilansampel dilakukan secara non probability sampling melalui consecutive samplingdengan jumlah responden sebanyak 90 orang. Analisa data multivariatmenggunakan uji statistik regresi multinomial. Hasil analisis menunjukkanterdapat hubungan yang signifikan antara ketakutan dengan reaksi nyeri (p value= 0,018). Anak yang takut memiliki peluang 5 kali untuk terjadinya reaksi nyerikategori menghindar dibandingkan anak yang tidak takut. Perawat perlumelakukan intervensi keperawatan yang dapat mengurangi ketakutan pada anaksehingga reaksi nyeri kategori menghindar dapat diminimalkan.

ABSTRACT
Invasive treatments to the children during the period of hospitalization cause painreactions. The nurses need to know the factors related to pain reactions. Thestudy aims to identify the factors related with pain reactions related to invasivetreatments. The design of this study is observational research with cross sectionalapproach by using non probability sampling method through consecutivesampling with the amount of 90 children respondents. Multivariate data analysisuse multinomial regression statistic test. The result of the analysis indicated thatthere was a significant relationship between fear and pain reaction (p value =0,018). The emergence of pain reaction ?avoidance? from the children who are infear is as much 5 times greater than children who are not in fear. Nurses need toconduct nursing interventions that can reduce fear in the children behavior inorder to minimize pain reaction in form of avoidance.;Invasive treatments to the children during the period of hospitalization cause painreactions.
