Christensen, R., Constable Fernandez, C., Topalian, N., Vaughan, L., Krenz, K., Pitman, A. and Fett, A.-K. (2025) ‘A systematic review of geographically informed ecological momentary assessment studies on the place-based correlates of mental health, substance use and wellbeing’, Landscape and Urban Planning, 264, 105487. https://doi.org/10.1016/j.landurbplan.2025.105487

Christensen and colleagues place environmental exposure inside lived time. Their review of 33 geographically informed ecological momentary assessment studies examines how GPS, GIS, mobile sensing and momentary self-report can connect specific places with mental health, wellbeing and substance use as experience unfolds. The methodological innovation is not simply mobility tracking, but the synchronisation of spatial context and psychological state in ways designed to reduce retrospective bias and increase ecological validity. Eleven studies focused on natural environments, nineteen on built-environment characteristics and three on ambient conditions, yet temporal associations remain comparatively underdeveloped despite the method’s longitudinal potential. The paper thus identifies a critical frontier: exposure cannot be reduced to residential buffers or static neighbourhood attributes when people move through changing environments during the day. Its wider bridge links environmental psychology, urban analytics and mobile methods, recasting place as a time-dependent exposure relation rather than a fixed container around residence.
