Tóm tắt	The Overtourism Perception Scale (OPS) measures residents' and visitors' concerns about excessive tourism, measuring crowding, environmental degradation, cultural erosion, infrastructure strain, and resulting experience quality diminishment. Rooted in carrying capacity theory (Shelby & Heberlein, 1986) and resident impact perception research (Andereck et al., 2005), the OPS operationalizes overtourism as a multifaceted phenomenon affecting both visitor experience satisfaction and community wellbeing. Overtourism is increasingly critical for destination sustainability; the OPS enables monitoring of perception trends and targeting of mitigation strategies (visitor dispersal, infrastructure investment, capacity management) before crises (resident backlash, environmental damage, reputation loss) occur.	The Perceived Value Scale for Tourism (PVST) measures visitors' judgments of whether tourism experiences deliver fair value—balancing perceived benefits (quality of experience, emotional satisfaction, novelty) against perceived costs (monetary price, time investment, effort). Rooted in Zeithaml's value perception theory (1988) and extended by Petrick (2002) to leisure contexts, the PVST operationalizes value as multidimensional (not price alone), capturing emotional and relative components alongside financial fairness. Value perception is a critical satisfaction driver and predictor of repeat visitation and word-of-mouth, particularly for experiences with high upfront investment and uncertain return.
