Psychological Tests in Arabic: A Review of Methodological Practices and Recommendations for Future Use.

Mental health research among Arabic speakers is increasing, and with it the need to assess psychopathology of Arabic-speaking populations, including natives, refugees, and immigrants. However, major challenges include the unavailability of appropriate Arabic tools, and the difficulty of judging whether available tools are appropriate. Critical judgment of psychometric tools is important, because they are used for high stake decisions such as clinical outcomes and diagnoses. We identified Arabic-language tests that measure constructs related to mental illness and health, critically analyzed their methodologies, and provided broad recommendations for future research. We conducted a systematic search query using four online databases and followed step-wise exclusions. We identified 115 articles published between January 1998 and August 2019 which produced 138 Arabic tests to screen or diagnose or plan treatment for psychological disorders. More than 80% of tests were translated or adapted from English using methods that are not comparable with the latest standards. Methods of establishing validity, reliability, and equivalence, were also limited, with one quarter not reporting reliability, and the majority using only one source of validity evidence. There is much room for improvement when making decisions about translation or adaptation designs, as well as conducting and reporting psychometric evidence.
