Astute observations in their analysis of modifying existing person--environment interaction theory in disability.
Jahiel and Scherer point out very astutely that time can be a baffling confounder in viewing disability, taxing our ability to meaningfully apply the International Classification of Function, Disability and Health (ICF) model to outcomes analysis. Their approach to segmenting person and environment is constructive. But distilling factors based upon an a priori self-determination of disability as part of the model may also undercut the validity of the larger construct. While the authors are to be applauded for their efforts to extend existing models of disability to address their current shortcomings, attention must also be given to important socio- or geo-political factors that may deserve more than a contextual discussion and their own place in this developing theory.
