Reliability and validity of a Farsi version of 18-item Mental Health Inventory

Mental health is an important criterion for people's health status. The 18-item mental health inventory is one of the short forms of mental health inventory. The aim of this study was to evaluate the psychometric performance of the Farsi version of MHI- 18. Data analysis showed MHI-18 is associated with GHQ Scores (r= -0.75). Factor analysis loaded two factors. Reliability for MHI-18 with Chronbach's alpha and spilt half method was 0.93. The results support internal consistency and factorial structure of MHI-18 and demonstrate that this scale is a valid and reliable instrument in Iranian population and can be used in clinical research and activity.
