Early detection of Autism Spectrum Disorder (ASD) has proven to be of high significance, however there is a limited availability of ASD screening tools in Serbian language. In this study we aim to translate, assess reliability and, in part, test the applicability of Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT R/F) in Serbian Healthcare environment. We screened 128 children in three primary healthcare centres and 20 children in a tertiary psychiatric center, using M-CHAT R/F translated into Serbian language, between December 2014 and October 2015. At the end of the screening process 80% of participants in the risk group screened positive for ASD, while in the control group 4 (3.1%) participants screened positive, with a mean total scores of 8.25 and 0.66 respectively. The Cronbach’s α coefficient was 0.91 and Guttman’s λ6 was 0.93. Test – retest reliability was deemed as acceptable, and no significant correlation was found between M-CHAT-R/F scores and Epworth Sleepiness Scale for children scores. The Serbian version of the M-CHAT-R/F has shown satisfactory reliability. We can therefore assert that it is a reliable tool for identifying ASD and it can be used in clinical practice to improve early detection, assessment and treatment.

(1) Background: Short Assessment of Health Literacy for Spanish Adults (SAHLSA-50) was originally designed for Spanish-speaking regions, and translations validated for several languages. The aim of the study was to adapt and verify the psychometric characteristics of SAHLSA-50 in the Croatian context; (2) Methods: The cross-sectional study included 590 respondents from the general population older than 18 years of age. Health literacy was measured by two scales: SAHLCA-50 and the Croatian version of the Newest Vital Sign screening test (NVS-HR), which was used as a measure of concurrent validity. Subjective Health Complaints (SHC) and Satisfaction with Life Scale (SWLS) questionnaires were also used to assess convergent validity; (3) Results: Internal consistency reliability of SAHLCA-50 was high and corresponds to the findings of the authors of the original research. The Cronbach alpha coefficient for SAHLCA-50 version was 0.91. The correlation of SAHLCA-50 with the NVS-HR test speaks in favor of concurrent validity. Correlation between health literacy and SHC speaks for convergent validity, just as was expected, while correlation with life satisfaction was not observed; (4) Conclusions: The SAHLCA-50 test can be a good and quick tool to assess health literacy of the adult population in the Croatian language. HL can affect the health and quality of life of the individual and the wider community.
