Penelitian ini menguji hubungan antara traits kepribadian gelap (Machiavellianisme, narsisme, psikopati, dan sadisme) dan motivasi kebermaknaan dalam memprediksi intensi pengorban diri (normatif dan non-normatif). Riset meta-analisis menunjukkan bahwa kepribadian gelap merupakan faktor signifikan yang penting terkait dengan pengorbanan diri. Studi dilakukan kepada 270 partisipan yang merupakan warga negara Indonesia berusia 18 tahun ke atas. Setelah melakukan skrining uji atensi, diperoleh 172 partisipan (Musia = 24,87, SDusia = 4,77; 58,72% perempuan) yang datanya dapat diolah untuk analisis. Hasil analisis Pearson Correlation menunjukkan adanya hubungan positif yang signifikan antara Machiavellianisme dan narsisme pada pengorbanan diri normatif. Sedangkan, masing-masing trait kepribadian gelap, yaitu Machiavellianisme, narsisme, psikopati, dan sadisme juga berkorelasi signifikan dengan pengorbanan diri non-normatif. Sementara itu, hasil analisis regresi PROCESS Model 1 Hayes menunjukkan bahwa motivasi kebermaknaan memoderasi trait Machiavellianisme dan narsisme dengan pengorbanan normatif. Sedangkan, pada pengorbanan diri non-normatif, motivasi kebermaknaan memoderasi hubungan trait Machiavellianisme dan sadisme secara signifikan.
