Abstract
Abstract:
Background and Aim
Increasing life expectancy and improving the quality of life of patients with cancer is one of the health
priorities. The attitude towards life is one of the most important effective factors. The objective of present
study was psychometric evaluation of revised life attitude scale in cancer patients undergoing chemotherapy.
Materials and Methods
This was a methodological study. 138 patients with cancer patients undergoing chemotherapy have been
selected by simple random sampling. First, the scale was translated to Persian. Internal consistency was
estimated using Cronbach's coefficient alpha. The validity was determined by constructed validity using
exploratory factor analysis exploratory, content validity (by calculating content validity index and content
validity ratio) and also face validity.
Results
Results of factor analysis showed six essential factors as the basis of Persian life attitude profile-revised
scale. The first factor (goals) explained the main portion of variance of scale’s questions. The index of
Kaiser-Meyer-Olkin showed the adequacy of sample size. (0.601). Content validity index was 0.79-0.85. The
content validity ratio for the above choices of scale was equal to +0.99 (p<0. 05).
Conclusions
According to the results of this study the Persian version of life attitude in patients scale in cancer patients
had appropriate validity and reliability. The mentioned tool is also suitable for researches and useful as a
screening tool in clinical environments.
