“…(Program was written by Franz Faul, Universität Kiel, Germany) (Faul, Erdfelder, Buchner et al, 2007; Faul, Erdfelder, Lang et al, 2009). Based on the study by Sulima et al (2014), a three-unit difference from the known average (44.27 ± 9.84), the effect size of 0.305, a power of 0.90, an alpha level of .05, and two-way hypothesis options were selected, and thus 115 participants were obtained after the operations. Considering that some data may be lost, the study was performed with 126 pregnant women by adding an extra 10% to 115 participants (63 in the intervention and 63 in the control groups).…”
