title: Toward a model of person-environment congruence: development of the EPPIS.
abstract: The Person Environment (P-E) Congruence model represents an approach to understanding the impact of the environment on the well-being and adjustment of elderly which may also provide information for the development of intervention programs at individual, group and/or institutional levels. Assessment of P-E congruence, or fit between the person and his/her environment, was operationalized in two studies through the development of the Environmental Perception, Preference and Importance Scale (EPPIS). the EPPIS provides scales to assess environmental perceptions, individual environmental preferences and the important or salience of the environment on 15 empirically derived, commensurate dimensions. In a third study, the four-month test-retest reliability of the overall P-E congruence score of the EPPIS, defined as the absolute difference between the perceived and preferred environment weighted by importance, was .78 while the unweighted model reliability was .76. Also, the 15 dimensions of the EPPIS were observed to be significant predictors of well-being. It was proposed that the EPPIS may be used both to determine areas of intervention which the elderly themselves feel are important and as a means to evaluate the effectiveness of interventions intended to reduce P-E incongruence and increase psychological well-being.
