Intervention model description

Assuming a power of 80% and an α risk of. 05, a sample size of 75 was determined to be appropriate. Considering the possibility of missing data, the study initially included 80 participants in both the experimental and control groups. A computer-based random number generator was used for group assignment, and allocation concealment was ensured by using sealed envelopes containing random numbers opened by a separate researcher. The study was completed with 40 participants in the experimental group and 40 in the control group, due to some participants withdrawing.
