The ADHD Lifespan Functioning Interview (ALFI) is a clinical interview developed to support a diagnostic assessment of ADHD in adults. The ALFI should be used in conjunction with the ALFI Manual, which provides information on how to administer and score the ALFI. Users are guided to ask questions about ADHD symptoms, personal history, school history, occupational history, antisocial behaviour, social functioning and presentation to services. Aside from garnering helpful qualitative information to support a clinical assessment, ratings are generated that can be used for research purposes. A version of ALFI that can be administered at follow-up to assess clinical and functional outcomes is also available (ALFI-2). Download all the ALFI materials here.
