title: Psychometric evaluation of novel measures of partner interfering and supportive behaviors among women with cancer.
abstract: The aim of this study was to evaluate the psychometric properties of complementary and novel measures of partner interfering and partner supportive behaviors in cancer care (PIB-C and PSB-C).
  
  
  
  Structured telephone interviews were conducted with 378 women (aged 18-79) in partnered relationships and recruited from the Kentucky Cancer Registry. Psychometric analyses of PIB-C and PSB-C were used to determine scale reliability, and scale construct and predictive validity (correlations with indicators of partner abuse, symptoms of depression, anxiety, and stress after cancer).
  
  
  
  Cronbach's alpha and split-half calculations indicated excellent internal consistency of the 20-item PIB-C (0.936 and 0.87, respectively) and 12-item PSB-C (0.930 and 0.89). Three thematic clusters for the PIB-C and two for the PSB-C were identified through factor analyses. Regarding construct validity, higher PIB-C and lower PSB-C scores were associated with a measure of psychological impacts from abuse. Predictive validity was suggested through (1) lower PSB-C associated with depression, (2) higher PIB-C associated with anxiety, and (3) higher perceived stress associated with higher PIB-C/lower PSB-C scores.
  
  
  
  Both PIB-C and PSB-C have strong psychometric properties and distinguish partner behaviors more likely to negatively impact women's depression, anxiety, and stress during cancer care/recovery. Use of these measures may assist clinical teams in comprehensively assessing women patients' home environment to best ensure cancer care/recovery. Copyright © 2015 John Wiley & Sons, Ltd.
