title: Neuropsychological correlates of complicated grief in older spousally bereaved adults.
abstract: OBJECTIVE
  Across many research domains, evidence for complicated grief as a distinct psychopathology continues to grow. Previous research from neuropsychology has shown an increased attentional bias to emotionally relevant stimuli in those suffering from complicated grief. This study furthers our understanding of the characteristics that distinguish complicated grief. We expand on previous research by (a) testing older adults, (b) excluding those with comorbid major depressive disorder, (c) using participant-chosen grief-related stimuli, and (d) using a married, nonbereaved control group.
  
  
  METHODS
  We recruited 76 older adults in 3 groups: spousally bereaved with complicated grief, spousally bereaved with noncomplicated grief, and nonbereaved controls. Performance on the Wisconsin Card Sorting Task, Digit Span Backwards, and the emotional counting Stroop was examined.
  
  
  RESULTS
  Results indicate longer reaction time across 3 blocks of grief-related words in the complicated grief group but no difference across 3 blocks of the neutral words. The 3 groups performed comparably on the other neurocognitive tasks, indicating no cognitive differences in working memory or set shifting between groups. Furthermore, these effects of complicated grief generalize to older adults and appear independent of major depression.
  
  
  CONCLUSIONS
  Complicated grief has cognitive interference as a neuropsychological component highlighting it as distinct from noncomplicated grief.
