Methodological shortcomings in the pre- and post-test design and consequences for the self-evaluation results.

Shortcoming	Consequence
Non-random sample of participants	It is unknown whether the participants represent AOD front-line workers in Queensland. If they are not representative, then the employ of the workshop materials may be non-random and concentrated in one sector leading to non-efficacious results. Mandatory recruitment also raises the question as to the motivational level of participants, especially those whose duties do not involve significant client engagement (e.g., receptionists).
Non-collection of participant’s socio-demographic information and absence of individual identifiers	Severely limits data analysis and heightens the possibility for erroneous conclusions to be made. Precludes any possibility of linking responses.
