  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.
  2. bCHESS = Changes in Health and End-Stage Disease Signs and Symptoms.
  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.
  4. dCPS = Cognitive Performance Scale.
  5. eN/S = Not significant at alpha = 0.05 level.
  6. fMean (Minimum-Maximum).
  7. gAssumes a CHESS cutoff of 3+ versus <3 (to improve discriminatory power in this smaller sample focused on patients with prognosis < 6 months).
