Artikel: Psychometric evaluation of novel measures of partner interfering and supportive behaviors among women with cancer (2016)

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).

Methods

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).

Results

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.

Conclusion

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.
