Tóm tắt	The hierarchical leisure constraints model proposes that the three types of constraint on recreation participation are not faced all at once but encountered in a fixed sequence, from the most personal to the most external. Crawford, Jackson and Godbey's 1991 paper in Leisure Sciences synthesized earlier work on intrapersonal, interpersonal, and structural constraints into a single ordered framework: a person must first overcome internal psychological constraints to form a preference for an activity, then resolve interpersonal constraints by coordinating with companions, and only then confront structural constraints such as cost and access. This ordering, which extended Crawford and Godbey's 1987 reconceptualization of leisure barriers, implies that the most powerful constraints are the intrapersonal ones encountered earliest, because they prevent a preference from ever forming. The model became the dominant organizing structure for constraints research and the foundation on which the later negotiation perspective was built.	The leisure constraints negotiation model studies how people who encounter obstacles to participation do not simply abstain but instead deploy strategies that allow them to take part anyway, often in modified form. Building on Crawford, Jackson and Godbey's tripartite classification of constraints into intrapersonal, interpersonal, and structural types, Jackson, Crawford and Godbey's 1993 paper overturned the prevailing assumption that constraints are insurmountable barriers, arguing instead that participation is the outcome of a negotiation process in which motivation and effort can offset constraint. Hubbard and Mannell's 2001 study formalized this insight by pitting four competing models of the constraint-negotiation process against one another with structural equation modeling, establishing the constraint-effects-mitigation model as the dominant account. The framework reframes non-participation as just one possible endpoint of an active negotiation rather than the inevitable consequence of facing a constraint.
