The Negative Effects Questionnaire (NEQ) has currently been translated into eleven different languages. Each translation is made by an authorized translator and in accordance with the coordinated framework agreements in Sweden, thereby ensuring a high standard, satisfactory reliability, and that each translation is made in compliance with the quality certification ISO 9001:2008. Furthermore, each translation has also been reviewed by clinical psychologists with the given language as their native tongue in order to make sure that the translation is easy to comprehend, feels unsophisticated, and does not include words or expressions that are unfamiliar to most people.
The self-report measure is free to download and use in both clinical and research settings. If implemented in clinical trials or similar studies, please include a reference to its original evaluation.
