Dear Editor,

A recent article published in this journal discussed the academic success of college students and introduced an instrument for measuring it [1] but did not discuss the factors affecting it. Self-esteem (SE) is one of the factors behind the students' academic achievement. It also affects the clinical performance of nursing, midwifery,[2] and other medical sciences students. SE is a person's satisfaction toward oneself, and a sense of being valued.[3] A number of studies have investigated the relationship between SE and academic achievement in nursing and other medical sciences students and reported positive correlation.[4],[5],[6] However, no specific review study in this regard is available among Iranian medical sciences students. Therefore, this study aimed to conduct a meta-analysis study to explore the relationship between SE and academic achievement of Iranian medical sciences students.

The search was done in national and international databases, including Magiran, IranMedex, Scopus, PubMed, Web of Science, and the Google Scholar search engine. The keywords were self-esteem, academic achievement, nursing, midwifery, medical, and students. Study selection and data extraction were done by two independent researchers. The search was done on March 1, 2019, without any time limit. The study was done based on the protocol for reporting a systematic review and meta-analysis.

Assessing the nursing and other medical sciences students' SE and academic achievement (i.e. the grade point average) and their relationship, being conducted in Iran and being published in Persian or English languages were selected as the criteria for inclusion of the studies. The correlation coefficient was selected as the estimate for effect size. Considering the correlation coefficient score within the range of −1≤r≤−1 and also the nonnormal distribution of the coefficient, the value was normalized applying equation. Then, the standard deviation was calculated using formula. Finally, the meta-analysis was performed on Z scores, and then the Z values were transformed to the correlation coefficient (r) using equation.

[Figure 1] shows the steps for searching and selection of the studies and [Table 1] presents the characteristics of the included studies. [Figure 2] illustrates the association between academic achievement and SE among the medical sciences students. The mean correlation coefficient between the academic achievement and SE scores was obtained as r = 0.20 (95% confidence interval: 0.18-0.22. The Chi-square was 4.72 (df = 5, P = 0.000) and the I2 showed low heterogeneity. The I2 is a numerical index for estimating ratio of the variance between studies and is utilized as a surrogate for probability index. The I2 values ≤25%, 26%–75%, and >75% signifies low, medium, and high heterogeneity, respectively.[9] Due to the small number of studies, it was impossible to conduct a subgroup analysis. However, it can be concluded that SE can improve academic achievement in medical sciences students. Due to the crucial effect of SE on academic achievement and clinical performance of nursing and other medical sciences students, special actions should be taken to strengthen the SE of these students. Assessing the effect of active and student-centered teaching methods on the students' SE and their academic and clinical performance is recommended.
