Introduction
This document presents research collated to inform the Guidelines for attention deficit
hyperactivity disorder (ADHD) 2008. The research questions and tables are organised to reflect
the order of the guidelines. Each table provides the lead author, a brief description of the sampleand the design, a brief description of the intervention or diagnostic criteria, the outcome measures
used and a brief conclusion. Readers are recommended to read the original articles for more
details.
Funding
The Royal Australasian College of Physicians gratefully acknowledges the financial assistance
for the development of these guidelines, which was provided by the Australian Government
Department of Health and Ageing.

Literature review methods
The aim of this systematic literature review is to assist in the development of guidelines for theassessment, treatment and care of individuals with ADHD. The methods used in the systematicreview comply with NHMRC requirements (1-4).
Literature searchesA comprehensive literature search for relevant research using multiple databases as well asinternet searching, pearling and hand searches was carried out for each research question (Table1). The literature review was designed to update the 1997 NHMRC Guidelines on ADHD. Theliterature searches were conducted to encompass the years1997 - 2007. Research publicationsmeeting the NHMRC designated levels of evidence I-IV were sought (4). In the first instance asearch was conducted to identify any systematic reviews or meta-analyses that were available toaddress each research question (Level I). If a systematic review or meta-analysis addressing the
research question was not identified the search limits were extended to include Level II evidence.In the absence of Level I or II evidence, Level III and IV evidence was sought. Search strategiesfor systematic reviews / meta-analyses and randomised controlled trials are described in Table 2.The searches for each question were conducted by one reviewer. Twenty percent of the searcheswere independently conducted and checked for agreement by a second reviewer.
Inclusion and exclusion criteria
A set of individual inclusion and exclusion criteria were developed for each research questionbased on study population, intervention, comparator, relevant outcomes, study design, searchperiod and language.
For all questions the identified studies were excluded on the following rationale. Animal studies Inadequate outcome data presented Review articles with no original data Sample size of less than 10 participants The article could not be located Articles that fall outside the NHMRC designated levels of evidence I-IV.

Study Selection Process
1. All citations identified for each question or for a designated group of questions werecollated into an Endnote database and duplicate references were removed.
2. The title and abstract of these citations were screened for relevance. Studies thatwould clearly not meet the inclusion criteria were excluded at the level of title andabstract.
3. The remaining studies were retrieved for assessment of the full-text.4. The inclusion and exclusion criteria were applied to each retrieved article by two
independent reviewers. Articles that did not meet the inclusion criteria followingassessment of the full-text were excluded and are listed with the reasons for exclusionwith each question. Articles that met the inclusion criteria were included for data-extraction and critical appraisal.
Data-Extraction and Critical appraisalData were extracted into standardised data-extraction / critical appraisal tables. The internal andexternal validity of all included studies was critically appraised based on the NHMRC criticalappraisal checklists (1) and the NHMRC interim levels and grades of evidence (4). In addition,the modified Overview Quality Assessment Questionnaire (OQAQ) (5-7) was used to assess thequality of systematic reviews and meta-analysis. The data-extraction / critical appraisal tables foreach included study are available from the RACP on request.
