Hasil penelitian menunjukkan bahwa sikap terhadap OSA memiliki hubungan positif yang signifikan dengan OSA (β=.1884, t(462)=4.5161, p<.05). Selain itu, variabel lain yang memiliki hubungan yang signifikan dengan OSA adalah jenis kelamin dan orientasi seksual. Meskipun demikian, perceived peer norms tidak memoderatori hubungan sikap terhadap OSA dengan OSA (β=-.0023, t(462)=-1.5836, p>.05). Terdapat beberapa kemungkinan yang dapat menyebabkan penelitian ini gagal menolak hipotesis null, seperti keterlibatan OSA partisipan yang kurang merata serta persentase jenis kelamin dan orientasi seksual yang cukup berbeda, serta terdapat kemungkinan perceived peer norms sebagai independen variabel.
