With the exception of Sample 6, all samples were recruited by the author. Sample 6 was recruited by the author, Addiction Unit clinical staff and a research assistant. Protocols for recruitment and supervision of the recruitment procedure were provided by the author. A summary of the studies and the way the samples were used in these studies are presented in Table 4.1. The data collected and instruments administered in each sample are reported in the methods and procedures sections of each of the studies.
The origin of the research was in the routine audit and evaluation of clinical services at the Leeds Addiction Unit and the programme of follow-up has ethical approval. Written consent for follow-up was given at the outset specifically by participants in these studies and the two consent forms used are shown in Appendix 17 and Appendix 18.
