Discusses data on S selection processes obtained from a literature survey and 52 members of the Association for Behavior Analysis. Choice of S samples is discussed in terms of marker variables, including age, gender, and diagnostic category, and S characteristics. S selection and recruitment procedures are explored in terms of S source, recruitment procedures, random selection, restrictions on generality, and informed consent. Issues related to S completion are also addressed. Emphasis is on the need for more detailed information about S selection and recruitment procedures and examination of S characteristics as they affect research outcome.
