      validity.

AB  - BACKGROUND: The recently refined Demoralization Scale-II (DS-II) is a 16-item, 
      self-report measure of demoralization. Its 2 factors-Meaning and Purpose and 
      Distress and Coping Ability-demonstrate sound internal validity, including item 
      fit, unidimensionality, internal consistency, and test-retest reliability. The 
      convergent and discriminant validity of the DS-II with various measures is 
      reported here. METHODS: Patients who had cancer or other progressive diseases and 
      were receiving palliative care (n = 211) completed a battery of questionnaires, 
      including the DS-II and measures of symptom burden, quality of life, depression, 
      and attitudes toward the end of life. Spearman rho correlations were determined to 
      assess convergent validity. Mann-Whitney U tests with calculated effect sizes 
      were used to examine discriminant validity and establish the minimal clinically 
      important difference (MCID). Cross-tabulation frequencies with chi-square 
      analyses were used to examine discriminant validity with major depression. 
      RESULTS: The DS-II demonstrated convergent validity with measures of 
      psychological distress, quality of life, and attitudes toward the end of life. It 
      also demonstrated discriminant validity, as the DS-II differentiated patients who 
      had different functional performance levels and high/low symptoms, with a 
      difference of 2 points between groups on the DS-II considered clinically 
      meaningful. Furthermore, discriminant validity was demonstrated, as comorbidity 
      with depression was not observed at moderate levels of demoralization. 
      CONCLUSIONS: The DS-II has sound psychometric properties and is an appropriate 
      measure of demoralization. Given its structural simplicity and brevity, it is 
      likely to be a useful tool in meaning-centered therapies. Cancer 2016;122:2260-7.
