“…In addition, the general rule of thumb as suggested by MacKinnon, Lockwood, Lockwood, West, and Sheets (2002) is that a sample size of 1000 is required to detect a small effect, a sample size of 100 is sufficient in detecting a medium effect, and a sample size of 50 is required to detect a large effect. In fact, based on previous research by the researchers with caregivers of persons with ASD (Bekhet, Johnson, & Zauszniewski, 2012), a medium effect size is used in the current study, therefore a sample of 117 caregivers in the current study is justifiable.…”
