We will assess the quality of studies in terms of the presence of randomisation, the methodology of outcome assessment, intention-to-treat analyses and attrition rates.
Each clinical trial was graded according to the presence or absence of key elements such as concealed randomization, blinded outcome assessment, intention-to-treat analysis, and explicit definition of a primary outcome.
The evidence base is characterised by studies in which well described randomisation, blinding of allocation or outcome assessment, intention-to-treat analysis and restriction of analysis to primary outcomes are the exceptions.
For variables with additional assessments, intention-to-treat populations both with and without last observation carried forward were analysed.
The most comprehensive evaluation was detailed in High School Coaches' Assessments, Intentions to Use and Use of a Concussion Prevention Toolkit [ 17], which consisted of an information letter and brochure, reference cards, fact sheets, posters and a video.
For it is when actions are seen as subject to moral assessment that intention becomes relevant.
The assessment of intention of a suicide attempt is especially difficult in adolescents as they may not correctly perceive the lethality of their attempt [ 39].
This trial includes a number of key methodological features which will minimise bias including randomisation, concealed allocation, blinded outcome assessment and intention to treat analysis.
The strengths of this study include adequate randomisation, allocation concealment, blinded outcome assessment, and intention to treat analysis, all of which minimises the risk of bias.
Future studies may seek to align further measures of behaviour with the time orientation of items relating to the assessment of intention (i.e. in the next four weeks of pregnancy).
In Knowing the Adversary: Leaders, Intelligence, and Assessment of Intentions in International Relations, Yarhi-Milo describes how leaders rely on "vivid" information — such as one-on-one meetings — while intelligence analysts focus on factors such as military capability.
