The spiritual dimension constitutes the fourth dimension of human existence, supplementing the other three: physical, psychological and social ones. It can both be conducive to health – by giving or rather continuous discovering of the purpose in life, suffering or dying, and it can have a negative impact – by idle devotion to the Supreme Being, involving passive waiting for an intervention or religious interpretation of causes of illness leading to experiencing it in sense of guilt, injustice or harm. The feeling of meaningfulness is expressed by an individual’s motivation to act, at the same time it is a degree to which a person experiences their existence both in the cognitive and emotional dimensions, reaching the final conclusion that their life makes sense. The presented research aims at checking whether and to what extent healthy people feel different from chronically ill persons in the intensity of the feeling of purpose in their own life, and whether individual groups of chronically ill persons differ in expectations about the future and assessment of their relations with relatives.
