“…The WHO-5 is a generic scale which is used to evaluate the general mental well-being of persons (Hall et al, 2011;Bech, 2012) in clinical settings. The WHO-5 was reported to be one of the very frequently used scales that measure mental wellness and quality of life in Primary Care settings in different population groups such as adolescents and students (Yusoff et al, 2013;Christensen et al, 2015;Downs et al, 2017); pregnant women (Mortazavi et al, 2015); individuals using primary care services (Henkel et al, 2004;Saipanish et al, 2009;Guðmundsdóttir et al, 2014;Christensen et al, 2015); and in population-based studies (Khosravi et al, 2015). Two main studies clearly mentioned the use and the superiority of the WHO-5 for screening mental well-being in PHC settings: Henkel et al (2003) observed that, being the briefest screening questionnaire (and therefore the most practical to use), the WHO-5 produced very high sensitivity (93%) and negative predictive values (98%) compared to the other questionnaires with standard cut-off points in their paper (Henkel et al, 2003), whereas Löwe et al (2004) concluded that, all three questionnaires (The Hospital Anxiety and Depression Scale, the Patient Health Questionnaire and the WHO-5) performed well in screening of the depressive mood (Löwe et al, 2004).…”
