Background: Misconceptions about ADHD stigmatize affected people, reduce credibility of providers, and prevent/delay treatment. To challenge misconceptions, we curated findings with strong evidence base. Methods: We reviewed studies with more than 2000 participants or meta-analyses from five or more studies or 2000 or more participants. We excluded meta-analyses that did not assess publication bias, except for meta-analyses of prevalence. For network meta-analyses we required comparison adjusted funnel plots. We excluded treatment studies with waiting-list or treatment as usual controls. From this literature, we extracted evidence-based assertions about the disorder. Results: We generated 208 empirically supported statements about ADHD. The status of the included statements as empirically supported is approved by 80 authors from 27 countries and 6 continents. The contents of the manuscript are endorsed by 366 people who have read this document and agree with its contents. Conclusions: Many findings in ADHD are supported by meta-analysis. These allow for firm statements about the nature, course, outcome causes, and treatments for disorders that are useful for reducing misconceptions and stigma.
We investigate deverbal zero-derived nominals in English (e.g., to walk > a walk) from the perspective of the lexical semantics of their base verbs and the interpretations they may receive (e.g., event, result state, product, agent). By acknowledging that, in the absence of an overt affix, the meaning of zero-nominals is highly dependent on that of the base, the ultimate goal of this study is to identify possible meaning regularities that these nominals may display in relation to the different semantic verb classes. We report on a newly created database of 1,000 zero-derived nominals, which have been collected for various semantic verb classes. We test previous generalizations made in the literature in comparison with suffix-based nominals and in relation to the ontological type of the base verb. While these generalizations may intuitively hold, we find intriguing challenges that bring zero-derived nominals closer to suffix-based nominals than previously claimed.
