Abstract This research aims to assess multilanguage versions of the IRQS-2018 to determine Intergenerational relationship quality in the older persons. In a psychometric investigation, the instrument was completed by 707 persons whose age is older than 60; those people were from 6 populated ethnic groups in Iran. It is noteworthy that the Rasch partial credit model (PCM) and the classic method were employed.The PCM showed that items 3 and 7 were misfitting in all versions of IRQS. Furthermore, consecutive response groupings for all items were situated in the predictable order, and the version of IRQS with 11-items had further interior consistency. Although Rasch analysis specified to pertinent of IRQS 11-Items, it should be assessed in additional investigations and deviating settings such as public residence grown-up adults.
