Kecemasan adalah gangguan psikiatri yang umum terjadi, terutama pada ibu hamil. perubahan hormon saat hamil dapat menyebabkan mood swing dan pelepasan kortisol yang berlebihan yang dapat berdampak negatif pada kesehatan ibu dan janin. deep breathing (relaksasi nafas dalam) merupakan terapi sederhana yang melibatkan pengaturan pola pernafasan secara perlahan, dengan menahan inspirasi dan menghembuskan nafas perlahan, metode ini efektif untuk mengurangi ketegangan otot, rasa jenuh dan kecemasan. adapun teknik relaksasi lainnya yaitu self-instruction training (sit) yang merupakan salah satu strategi yang dapat membantu ibu hamil untuk mengganti pemikiran negatif menjadi pemikiran yang positif. tujuan dari penelitian ini yaitu untuk mengidentifikasi tingkat kecemasan pre dan post intervensi deep breathing dengan teknik self-instruction training melalui media audio. penelitian ini menggunakan metode kuantitatif dengan desain quasi-experimental one group pretest-posttest, melibatkan 46 ibu hamil di kecamatan sebatik tengah. instrumen yang digunakan adalah kuesioner hars (hamilton anxiety rating scale). hasil pre-intervensi menunjukkan tingkat kecemasan yang bervariasi, sebanyak 30,4% responden mengalami kecemasan ringan hingga berat sekali. setelah intervensi, 54,3% responden tidak mengalami kecemasan. analisis wilcoxon signed-rank menunjukkan ada pengaruh yang signifikan dari deep breathing dengan teknik self-instruction training melalui media audio terhadap pengurangan kecemasan pada ibu hamil, dengan p value= 0.001 (α < 0,05). kesimpulannya penerapan relaksasi sangat penting untuk mengurangi kecemasan pada ibu hamil, terutama di daerah perbatasan. intervensi deep breathing dengan teknik self-instruction training ini diharapkan dapat diterapkan di lingkungan puskesmas atau klinik yang sering dikunjungi oleh ibu hamil, agar intervensi ini dapat diintegrasikan dalam pelayanan kesehatan. kata kunci: kecemasan, deep breathing, self-instruction training, ibu hamil

Anxiety is a common psychiatric disorder, especially among pregnant women. hormonal changes during pregnancy can cause mood swings and excessive cortisol release, which can negatively affect the health of the mother and fetus. deep breathing (deep breathing relaxation) is a simple therapy that involves regulating breathing patterns slowly by holding the inhalation and exhaling slowly. this method is effective in reducing muscle tension, boredom, and anxiety. another relaxation technique employed is self-instruction training (sit), a strategy that has been demonstrated to facilitate the transition of negative thoughts to positive ones in pregnant women. the objective of this study is to ascertain the pre-and post- intervention anxiety levels associated with deep breathing techniques employing self-instruction training techniques through audio media. the present study used a quantitative method, utilizing a quasi-experimental one-group pretest-posttest design, encompassing 46 pregnant women in central sebatik district. the instrument used was the hamilton anxiety rating scale (hars) questionnaire. before the intervention, the results obtained indicated that a significant proportion of the respondents exhibited varying degrees of anxiety, with 30.4% reporting levels ranging from mild to severe. the present study used a quantitative method, employing a quasi-experimental one-group pretest-posttest design, encompassing 46 pregnant women in central sebatik district. the instrument used was the hamilton anxiety rating scale (hars) questionnaire. before the intervention, the results obtained indicated that a significant proportion of the respondents exhibited varying degrees of anxiety, with 30.4% reporting levels ranging from mild to severe. after the intervention, anxiety levels markedly diminished, with 54.3% of respondents indicating no sense of anxiety. the deep breathing technique and audio-based self-instruction training markedly diminished anxiety in pregnant women (p= 0.001, a < 0.05, as per wilcoxon signed-rank analysis). keywords: anxiety, deep breathing, self-instruction training, pregnant women
