1. CAARS: Conners' adult self-reporting scale

At the moment, there is no publicly available Arabic version of the CAARS. This instrument is proprietary and typically requires purchase through authorised distributors. For research purposes, I would advise that you contact the publisher to request information on Arabic translations or permissions for adaptation.

2. TCI-R: temperament and character inventory, revised version

An Arabic version of the TCI-R has been developed and validated in Moroccan Arabic. This version was tested among medical students and demonstrated acceptable psychometric properties for most dimensions. However, some scales, such as Reward Dependence and Persistence, showed lower reliability. This version could be suitable for research in North African contexts. You can consider using the Moroccan Arabic version if it aligns with your research population.

3. EPQ-R:

The EPQ-R has been translated into Arabic and validated in various studies: A study conducted in Kuwait assessed the psychometric properties of the Arabic EPQ-R short scale among undergraduates, finding satisfactory reliability for most scales. Another study in Algeria examined the factorial structure of the EPQ-R on an Algerian sample, confirming its applicability in that context. The validated Arabic versions from Kuwait or Algeria have been utilised in academic research and could be appropriate for your thesis.
