PERSON
Person: adaptive system constantly interacting
with external and internal environment
Persons major task: Maintain personal
integrity (wholeness) in face of
environmental stimuli.

13. Environment is the second major concept of the model.
The environment refers to all conditions and circumstances and influences
surrounding and affecting the development and behavior of persons and
groups, with particular, consideration of mutuality of person and earth
resources.
It is the changing environment that stimulates the person to make adaptative
responses.

ENVIRONMENT
According to Roy, stimuli from within the human adaptive system & stimuli from around the
system represent the element of internal & external environment.
Roy specifically defines environment as “all conditions, circumstances & influences that
surround & affect the development & behavior of humans as adaptive systems, with particular
consideration of person & earth resources”.

15. Roy wrote about health as existing along a continuum, she now
views this conceptualization of health as simplistic and un realistic .
Wellness and illness excludes individuals with chronic disabilities or
terminal illness who in spite of their condition, are dealing effectively
with life's challenges.
In either conceptualization, health is viewed as a reflection of
adaptation.
