Data based investigation of the peer education methods on self-efficacy in patients with myocardial infarction using a randomized control trial design

This database aims to show the effects of peer-education (PE) on self-efficacy in patients with MI referring to Zabol Emam Ali Hospital in 2016. The data provided in this paper are for a descriptive-analytical and experimental study which included 70 patients with MI that randomly assigned to PE group (n = 35) and control group (n = 35). We used two tools for data collection in this data article. Patient׳s demographic data questionnaire, consisting of two parts: the first section had questions about general details such as age, education, marital status, while the second section had questions about health status information. Cardiac self-efficacy questionnaire was the second questionnaire. Finally, the data of 30 intervention and 30 control individuals were then analyzed by SPSS software and P value < 0.05 was considered to be statistically significant. The data indicated that PE can be useful for providing a better care in MI patients, thus, it is recommended that it׳s better to use this training method besides the routine training of nurses for MI patients.

Researcher-made and validated questionnaire analysis Data format Raw, analyzed, descriptive and statistical data Experimental factors Sample consisted of 70 patients with acute MI, who were randomly divided into two groups of intervention (PE) and control groups (data are presented in the Fig. 1).
After inviting the patients, the researcher-made questionnaire including demographic data and questions which were related to the effects of peer-education on quality of nursing were completed. The cardiac self-efficacy rate in two groups were investigated by filling out the cardiac self-efficacy questionnaire. The data was collected at the baseline and then after four weeks of the intervention. Experimental features -Data was gathered using a randomized control trial (RCT) design.

Value of the data
The data can be used by clinicians and health policy makers in order to provide a better care for MI patients.
The data provides information about the effect of PE on the self-efficacy in patients with MI which is important in management of MI.
Our data showed that implication of PE for MI patients may resulted in a higher self-efficacy compared to those who were received routine nursing education.
The data suggests that PE can be useful for providing a better care in MI patients, thus, it is recommended that it's better to use this training method besides the training of nurses for MI patients.

Data
MI is the most common cardiovascular disease [1]. Sol et al. [2] reported that patients with cardiovascular disease can effectively control and manage the signs and symptoms of their disease by improving self-efficacy [2]. Also, educating and improving self-efficacy of patients with MI is important to take care of them [3]. Table 1 represents basic characteristics of patients with MI in two groups of PE and control. According to the Table 1, most patients were 51-60 age group (P ¼ .26), and majority of the participants were male with no difference between two groups (P ¼ .78). According to the data of the present article, 66.7% of intervention group and 46.7% of control group had lower education (P ¼ .06) and the rate of smoking was equal among two groups (60%). Table 2 shows that there is no statistically significant difference in means (7 SD) of self-efficacy between the PE and control group before the intervention. According to the Table 3, our data suggests a significant difference in mean (7 SD) of self-efficacy between pre-and post-intervention among intervention group (P ¼ .001) and this association was not found for control group (P ¼ .30).

Study area description
The data was gathered at the Zabol teaching hospital, affiliated with the Zabol University of medical sciences in Zabol, Sistan and Baluchestan Province, Iran. The canter is a principle referral center for all disease including hurt disease in this province [4]. This province is located in the Southeast of the country, neighboring two countries including Pakistan and Afghanistan. The province is one of the largest one in country, with an area of 181,785 km 2 and its population is estimated to be around 2.5 million. Zabol county has around 130,600 populations and it is located near Lake Table 3 Mean and standard deviation of self-efficacy score in two groups of peer education and control before and after intervention. Hamun [5]. Fig. 2 Illustrates the overview of the city. Zabol teaching hospital with 422 beds is located in the centre of Sistan and Baluchestan in the Southeast of Iran.
As shown in Fig. 1 in total we assessed 174 patients for eligibility, of them 96 patients did not meet our inclusion criteria and 18 declined to participate. Finally, we include 70 patients with MI that randomly assigned to PE group (n ¼ 35) and control group (n ¼ 35). We used two tools for data collection. Patients' demographic data questionnaire, consisting of two parts: the first section had questions about general details such as age, education, marital status, while the second section had questions about health status information-these were set after literature evaluation and consultation with professors who were expert in cardiovascular diseases. Cardiac self-efficacy questionnaire was the second questionnaire. The questionnaire Reliability was confirmed with coefficient Alfa 0.91. Then, the data of 30 intervention and 30 control individuals were analyzed using SPSS version 24. The data were analyzed, applying descriptive and statistical tests including independent t-test and pair t-test. P value o .05 was considered to be statistically significant.
