Travis’ Illness-Wellness Continuum
composed of two arrows pointing in opposite directions and joined at a neutral point
HEALTH AND ILLNESS
33
movement to the right on the arrows (towards high-level wellness) equals an increasing level of health and well-being
achieved in three steps:
awareness education growth HEALTH AND ILLNESS
34
movement to the left on the arrows (towards premature death) equates a progressively decreasing state of health
achieved in three steps:
signs symptoms disability HEALTH AND ILLNESS
35
most important is the direction the individual is facing on the pathway
if towards high-level health, a person has a genuinely optimistic or positive outlook despite his/her health status if towards premature death, a person has a genuinely pessimistic or negative outlook about his/her 36 HEALTH AND ILLNESS
compares a treatment model with a wellness model
if a treatment model is used, an individual can move right only to the neutral point
e.g., a hypertensive client who only takes his medications without making any other life-style changes
if a wellness model is used, an individual can move right past the neutral point
e.g., a hypertensive client who not only takes his medications, but stops smoking, looses weight, starts an exercise program, etc. HEALTH AND ILLNESS
