Abstract Introduction Thalassemia, as the most common chronic hereditary blood disorder in humans, can impose many adverse effects on parents and their affected children. On the other hand, positive thinking is the method or the result of a positive focus on a constructive issue, so by teaching positive thinking, we can improve physical and social function, and promote emotional health and overall quality of life. The aim of this study was to determine the effect of positive thinking training on the quality of life of parents of adolescents with thalassemia. Methods This quasi-experimental study was performed on 52 parents of adolescents with thalassemia who attended Taleghani Hospital in Golestan province, Iran in 2017. Samples were randomly assigned into two groups of intervention and control. The positive thinking training (based on the theory of Martin Seligman) was carried out in the intervention group in 10 (45–60 min) sessions over a 5-week period. Data collection tools in this study were the World Health Organization (WHO) quality of life questionnaire (WHOQOL-BREF) and a demographic information questionnaire. Data were analyzed by SPSS-16 software using independent t-test, the paired t-test and a covariance test. Results The results of paired t-test showed a significant difference in the score of quality of life in intervention group before and after the intervention (p < 0.001). However, this test did not show any significant difference in the control group (p = 0.11). The covariance test, after removing the pre-test score, showed a significant difference between the intervention and control groups in terms of the score of quality of life, so that 13% of the changes after the intervention were due to the intervention (p = 0.009, η = 0.13). Conclusion The positive thinking training increased the quality of life of parents of adolescents with thalassemia. Therefore, using this program can be an effective way of improving the quality of life of parents. Thus, positive thinking training is suggested to be used as an effective strategy for increasing the quality of life of parents with ill children.
