Summary	Recreation substitutability analysis studies the interchangeability of leisure experiences, asking when and for whom one recreation activity, site, or time can acceptably replace another. Bo Shelby and Jerry Vaske's work, exemplified by their 1991 study of salmon fishing in New Zealand, organized substitution into distinct types, varying the activity, the resource or setting, the timing, or the strategy of participation, and measured anglers' willingness to accept each kind of substitute when their preferred option was unavailable. Seppo Iso-Ahola's 1986 theory framed substitution as a psychological process in which perceived freedom of choice is the critical mediator: people substitute more willingly when they feel they are choosing rather than being forced, and when the alternative shares the valued qualities of the original. The analysis combines a typology of substitution with measures of willingness conditioned on choice freedom, the quality of alternatives, and recreationists' specialization and commitment.	The Recreation Experience Preference (REP) scales are a hierarchical battery of self-report measures, developed by B. L. Driver and colleagues over three decades, that quantify the desired psychological outcomes people seek from recreation. Rather than asking which activity someone prefers, REP asks why — capturing the experiences a person hopes to attain, organized into broad domains (such as enjoying nature, escaping pressure, achievement, affiliation, and learning) that each contain narrower scales. Manfredo, Driver, and Tarrant's 1996 meta-analysis in the Journal of Leisure Research consolidated more than three dozen studies that had used REP items, documenting a stable factor structure and reliable subscales and establishing REP as the standard motivational measure in outdoor recreation. The instrument operationalizes the behavioral, or expectancy-valence, view that recreation is goal-directed: people choose settings and activities expecting to satisfy specific experiential goals.
