To assess efficacy in patients with heart failure need to have a scientific tool based on psychometric features is evident. The researchers developed a scientific tool based on psychometric principles for assessing self-efficacy beliefs in patients with Myocardial Infarction (MI) as the only tool of its kind; however, Due to the large number of questions in the questionnaire, respondents may not desire to complete it accuracy. The present study was conducted to develop and validate a short form of this tool. This study was conducted on a sample of 311 patients diagnosed with MI by a cardiologist and selected through convenience sampling. The 80-20 rule was used for evaluating the 60 items of the short-form MI Self-Efficacy Measurement Tool (SF-SEMT) and for eliminating items without an adequate sensitivity and accuracy. The factor analysis revealed 5 factors that explained a total of 87.92% the variance; the kaiser-meyer-olkin index was calculated as 0.915 with a probable significance level of 0.001. A total of 22 items and 5 factors were extracted for this short-form tool. The reliability of the tool was confirmed with Cronbach’s alpha coefficients of 0.96 to 0.97 for the factors and 0.97 for the entire tool. The short-form MI self-efficacy measurement tool has better psychometric features than the original long form, as the former was found to have a better factor structure compared to the latter
