Abstract

Objectives The Coping Strategies Inventory-Short Form (CSI-SF) measures four coping strategies based on 16 items: 4 items each indicating problem- vs. emotion-focused engagement or disengagement. Here we provide the first assessment of reliability and construct validity of the CSI-SF among hemodialysis patients across 13 countries. Methods The CSI-SF was completed by patients in 9 languages in phase 4 of the Dialysis Outcomes and Practice Patterns Study (2009–11). Cronbach's alpha was used to assess internal consistency. Exploratory and confirmatory factor analyses were applied to assess the factor structure of the CSI-SF by country and language. CSI-SF data were analyzed from 7201 patients (60% male; median age 62.5 [range 18–96] years). Results Good internal consistency (α = 0.56–0.80) was seen for three scales in English (US, UK, Canada, Australia, New Zealand), German, and Swedish versions. The fourth scale was internally consistent if two items were dropped. In these countries, both exploratory and confirmatory factor analyses indicated a factor structure consistent with the four CSI-SF scales. Other language versions showed a factor structure inconsistent with these four scales. Conclusion The slightly modified English, German, and Swedish versions of the CSI-SF are reliable and valid instruments for measuring coping strategies in hemodialysis patients.
