For details of quality scores of included studies see Additional file 2 (Adequacy of included studies), and of the quality scoring tools used see Additional file 3 (Quality and validity tools).
Hence, in terms of true validity, the tool can only be used in those populations where the original tool is validated but they have Spanish speakers as well.
Internal structure (reliability, 22 tools) and content validity (14 tools) when described were found to be moderate.
The PEPA, training for use, inter-rater reliability information, construct and predictive validity, and tool usefulness are described.
An external validity assessment tool (EVAT) was developed based on previous work by others.
The EVAT also expanded on existing external validity assessment tools by modifying/adding items and protocol language to make the tool relevant to environmental and policy interventions as well as individually based programs.
To investigate the predictive validity of tools commonly used to assess the risk of violence, sexual, and criminal behaviour.
The results showed a positive, significant and generalisable convergent validity between tools, in the psychopathy dimension, as well as in the affective and anti-social factors.
Data collection methods, modes, and techniques; validity of tools.
Thus, there is variation in smoking susceptibility questions and validity of tools is questionable.
