Aims Childhood chronic disease is rising dramatically throughout the world. This study aimed to determine the construct and convergent validity and internal consistency of Family Management Measure. Instrument Methods This descriptive study was carried out with a methodologic research approach involving 300 mothers of children with chronic diseases in 2017. The convergent validity was assessed, and the confirmatory factor analysis was perfumed for construct validity. The internal consistency of the tool was assessed by calculating Cronbach’s alpha coefficient. Corrected Item Total Correlation of items was calculated. Lisrel 8.8 and SPSS 24 were used. Findings The results showed that the model of the six scales had a relatively good index. The correlation between the FaMM scales and The General Functioning Scale in the convergent validity was significant and in the predicted directions (r=-0.293, -0.379, -0.621, 0.255, 0.401, 0.358). The Cronbach’s alpha values for the scales were between 0.78 and 0.94, and the corrected item-total correlation was above 0.30. Conclusion According to the study results, the Persian version of FaMM has acceptable validity and reliability. Therefore, this tool can evaluate the management of families with a child with a chronic disease.
