THALASSEMIA
In the present quasi-experimental study, 99 patients with thalassemia at Shahid Beheshti Hospital in Yasuj, Iran, in 2019 who were eligible to enter the study, were selected. The block randomization was done with the block sizes of 3, 6, and 9, and participants were randomly assigned to 3 groups: smartphone application (A), lecture intervention (B), and control (c). Smartphone application and lecture interventions were performed for intervention groups A and B, respectively, during 8 weeks. Scherer's self-efficacy measure was used to collect the data at baseline and eight weeks after the intervention. Data were analyzed by SPSS-version 25 software using Paired t-test, Wilcoxon and Kruskal–Wallis tests.
