Kesulitan belajar siswa pada materi kimia telah menjadi perhatian dalam beberapa penelitian sebelumnya, kajian yang secara khusus membahas faktor-faktor penyebab kesulitan belajar siswa pada materi hukum dasar kimia kelas X Fase E SMA masih terbatas. Penelitian ini bertujuan untuk mengetahui validitas instrumen angket faktor-faktor penyebab kesulitan belajar siswa pada materi hukum dasar kimia Kelas X Fase E SMA secara teoritis yang dikembangkan. Studi ini menggunakan metode pengembangan (Research and Development) yang merujuk pada tahapan pengembangan skala yang dikemukakan oleh De Vellis tahun 2017 yang terdiri dari penetapan konstruk, penyusunan butir pernyataan, penetapan format pengukuran, validasi oleh para ahli, dan revisi instrumen, dengan melibatkan lima dosen kimia sebagai validator ahli. Data dikumpulkan menggunakan instrumen angket dan dianalisis dengan teknik analisis Aiken’s V. Hasil menunjukkan bahwa instrumen memperoleh rata-rata dengan nilai Aiken’s V sebesar 0,88 sehingga dinyatakan dalam kategori valid. Oleh karena itu, instrumen angket yang dikembangkan memenuhi kriteria validitas isi sehingga dapat digunakan untuk mengidentifikasi faktor-faktor penyebab kesulitan belajar siswa pada materi hukum dasar kimia. Instrumen ini dapat berkontribusi bagi pengembangan pendidikan melalui penyediaan instrumen angkat faktor-faktor kesulitan belajar.
