Abstract

PURPOSE
The purpose of this study was to develop a scale to evaluate posttraumatic growth in patients with cancer and to examine the validity and reliability of the scale.
METHODS
A literature review, semi-structured patient interviews and an expert panel consultation produced a 27 preliminary item questionnaire. Participants were 150 cancer patients recruited to test the reliability and validity of the preliminary scale. Data were analyzed using item analysis, exploratory factor analysis, convergent validity and internal consistency.
RESULTS
Item reduction and exploratory factor analysis led to 23 items, grouped into five subscales which were labelled new possibilities (6 items), coping skills (5 items), preciousness of life (5 items), relating to others (4 items), and personal strength (3 items). Convergent validity was evaluated by total correlation with the Functional Assessment of Cancer Therapy-General (r=.45, p<.001). The final scale demonstrated satisfactory internal consistency (Cronbach's α =.94).
CONCLUSION
Findings from this study indicate that the Cancer-Specific Posttraumatic Growth Inventory has validity and reliability and is considered to be appropriate for assessing posttraumatic growth in patients with cancer.
