Prestasi belajar anak yang dimediasi oleh peregulasian-diri dalam belajar dipengaruhi secara tidak langsung oleh dukungan ibu sebesar = 1,26; p = 0,00, nilai R2 = 0,25.

This correlational study was conducted at the grade 9 students of SMP Muhammadiyah Malang. The study involved 184 students determined based on the purposive sampling technique. The Child and Adolescent Social Support Scale (CASSS) and the Self-Regulation of Learning Self-Report Scale (SRL-SRS) were used to measure the mother's support, while the child's learning achievement was measured based on the child's report card score.
