  1. a“High” life satisfaction indicates that the patient has all 5 of the following conditions present: a sense of completion, a sense of progress towards completion, acceptance of the situation, inner strengths that can be encouraged/nurtured AND a positive outlook. “Low” life satisfaction” indicates that one or more of the 5 conditions are absent in the patient.

  3. c“Sleep disorders” is a composite (summative) measure based on two items: too little sleep (5 severity levels ranging from 0 to 4) and too much sleep (5 severity levels ranging from 0 to 4). “Severe” sleep disorders represent scores of 4+, “moderate” are scores of 2 or 3, and “minimal” are scores of 0 or 1.
