Thanks, Thomas. I did a search and didn't find any papers that provided or mentioned validated cut-off scores for the SDQ self-report Arabic version. More common is to use cut-offs validated on a different version (e.g., parent report for younger children) or different population (e.g., US or UK).
Thanks very much. I just requested the full text from the authors. From the abstract, however, it looks like they set cut-offs for measures other than the SDQ and used the SDQ to calculate convergent validity (I'm assuming they correlated the scales). Not clear to me whether they established a clinical cut-off for the SDQ as well.
