title: Pediatric oncology: the use of cluster analysis to examine maternal concerns.
abstract: OBJECTIVE
  To examine data from mothers whose children have cancer and to identify the characteristics of uncertainty and distress that they reported. The objectives were (a) to use cluster analysis to identify subgroups of maternal uncertainty and distress, (b) to examine whether the subgroups differed based on demographics and children's illness-related variables, and (c) to explore whether mothers in the subgroups differed on quality of life (QOL) and hope.
  
  
  METHODS
  Descriptive, correlational study.
  
  
  METHODS
  Pediatric oncology units in northern Taiwan.
  
  
  METHODS
  200 mothers of children with cancer.
  
  
  METHODS
  Participants completed the Parental Perception of Uncertainty Scale, the Symptom Checklist-35-Revised, the Short-Form 36 Health Survey, the Herth Hope Index, and a demographic questionnaire. Cluster analyses were used to identify subgroups of mothers regarding maternal perceived uncertainty and distress. Differences in demographic variables, disease characteristics, and outcome measures were evaluated with descriptive statistics, analysis of variance, and chi-square analysis.
  
  
  METHODS
  Subgroup, maternal uncertainty, distress, QOL, and hope.
  
  
  RESULTS
  Four subgroups were identified by the cluster analyses: high uncertainty and high distress, moderate uncertainty and moderate distress, low uncertainty and low distress, and high uncertainty and low distress.
  
  
  CONCLUSIONS
  The subgroup of mothers who reported low uncertainty and low distress reported the highest QOL and hope.
  
  
  CONCLUSIONS
  The findings of this study provide insight for pediatric oncology clinicians and offer issues related to uncertainty, distress, and QOL that such professionals can discuss with the mothers of their patients.
