“…Originally developed in English for use in the United States, these instruments have been translated to several other languages and extensively used in other settings as measures of nonspecial psychological distress and serious mental illness (SMI; see below) in epidemiologic studies (Aldworth et al, ; Arnaud et al, ; Carra et al, ; Donker et al, ; Fassaert et al, ; Han, Gfroerer, Colpe, Barker, & Colliver, ; Kessler et al, ; Kessler et al, ; Sakurai, Nishi, Kondo, Yanagida, & Kawakami, ). These measures have also been clinically used as screeners for establishing treatment referrals in PHC settings and for disability claimants (Allen et al, ; Cornelius, Groothoff, van der Klink, & Brouwer, ; Donker et al, ; Fassaert et al, ; Furukawa, Kessler, Slade, & Andrews, ; Kessler et al, ). We further compared the psychometric properties of these measures with the 12‐item General Health Questionnaire (GHQ‐12) that has been validated and extensively used in Iran (Bahremand et al, ; Emami, Ghazinour, Rezaeishiraz, & Richter, ; Heidari, Feizi, Roohafza, Hassanzadeh Keshteli, & Adibi, ; Montazeri et al, ) and other countries (Danielsson, Lundin, Allebeck, & Agardh, ; Diniz et al, ; Padron, Galan, & Rodriguez‐Artalejo, ; Pope et al, ).…”
