    Objectives. To examine the comorbidity between choice of drug and ADHD and to investigate the accuracy of a self-reported BADDS scale in identifying ADHD in adults. Methods. Forty consecutively recruited patients with SUDs were divided by choice of substance into three groups and administered DSM-IV semi-structured interviews and self-report questionnaires. Results. The groups did not differ as regards the prevalence of ADHD, the prevalence of which was 22.5%. The concordance between the tools used was 77.5% (κ 0.50). Conclusions. ADHD is unrelated to choice of drug so all patients with SUDs should be assessed for ADHD. The introduction of a self-reporting tool in the assessment process would reduce diagnostic errors

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
