Rahe concluded that:
-If the environment that pps are in is stressful, previous life events have less effect on illness.
-Better predictions can be made for older pps (over 21) and also for enlisted married men, than for young single sailors.
-There was a low-order positive relationship between pre-cruise life change intensity and reported illnesses at sea.
-The amount of earlier stress and illnesses experienced by all the sailors was low- if a population with greater illness variability had been used a stronger relationship may have occurred.
