Kehadiran Anak Berkebutuhan Khusus (ABK) membawa pengaruh bagi perkawinan. Adanya periode-periode kritis, tekanan psikososial, serta proses penerimaan terhadap anak yang hanya dilalui oleh orang tua ABK dapat membawa pengaruh bagi dinamika perkawinan. Selain itu, beratnya beban pengasuhan, perawatan dan pendidikan ABK menjadikan mereka lebih terfokus pada buah hati sehingga waktu untuk berinvestasi dalam perkawinan menjadi sedikit. Minimnya interaksi, keintiman, hingga memburuknya komunikasi antar pasangan dapat mempengaruhi kualitas hingga stabilitas perkawinan. Penelitian ini meneliti peran kepuasan perkawinan sebagai mediator dalam hubungan antara perilaku memelihara hubungan dan komitmen perkawinan. Partisipan penelitian merupakan orang tua dengan ABK yang tengah menjalani perkawinan pertama serta tinggal satu atap dengan pasangan. Walaupun demikian, hanya satu partisipan saja yang diukur dalam penelitian ini. Terdapat 142 partisipan yang didapatkan secara convenience sampling dan snowball sampling. Seluruh partisipan telah mengisi kuesioner Relationship Maintenance Behavior Measure untuk mengukur perilaku memelihara hubungan, Quality Marriage Index untuk mengukur kepuasan perkawinan, serta Marital Commitment Inventory untuk mengukur komitmen perkawinan. Dari hasil analisis mediasi ditemukan bahwa kepuasan perkawinan memedisi hubungan antara perilaku memelihara hubungan dengan komitmen perkawinan, baik komitmen personal, komitmen moral, serta komitmen struktural. Dari hasil penelitian dapat disimpulkan bahwa pada orang tua ABK, perilaku memelihara hubungan dapat memberikan pengaruh signifikan dan menyeluruh terhadap komitmen personal, moral serta struktural apabila kepuasan perkawinan telah dirasakan oleh orang tua terlebih dahulu.

The presence of children with special needs influences marriage. The existence of critical periods, psychosocial pressure, and the process acceptance of children, that only they go through, may influence the dynamics of marriage. In addition, the heavy burden of nurturing, caring and educating children with special needs makes them more focused on their children so that they have less time to invest in marriage. The lack of interaction, intimacy, and poor communication between partners can affect the quality and stability of marriage. This study examines the role of marital satisfaction as a mediator in the relationship between relationship maintenance behavior and marital commitment. Research participants are parents with special needs children who are undergoing their first marriage and live under the same roof. However, only one participant was assessed in this study. There were 142 participants obtained by convenience sampling and snowball sampling. All participants have filled out the Relationship Maintenance Behavior Measure questionnaire to measure relationship maintenance behavior, the Quality Marriage Index to measure marital satisfaction, and the Marital Commitment Inventory to measure marital commitment. From the results through the mediation analysis, it was found that marital satisfaction mediates the relationship between relationship maintenance behavior and marital commitment, both personal commitment, moral commitment, and structural commitment. From the results of the study, it can be concluded that in parents with special needs children, relationship maintenance behavior can have a significant and comprehensive influence on personal, moral and structural commitment if marital satisfaction has been felt by parents first.
