Abstract CN53
Background
The Brief COPE Inventory has been proven as acceptable psychometric properties and become the most often used instrument to examine various coping strategies among cancer patients. However, most of the psychometric properties testing studies have been conducted in Western countries which have different cultures, beliefs and norms, raising concerns with their relevance and applicability in Indonesian cultural context. The purposes of this study were to present psychometric properties of the Brief COPE in a sample of advanced cancer patients in Indonesia. Specifically, we aimed at examining the factorial structure as well as the validity and reliability of the measure.
Methods
This is a cross-sectional study with a secondary data analysis. The study included 440 patients from parent study who completed the Indonesian version of Brief COPE. The Quality of Life (Functional Assessment of Cancer Therapy-general) and Depression, anxiety and Stress (DASS scale) were also measured. Explaratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess factor structure and to evaluate the structural model fit, respectively. Reliability was demonstrated by internal consistency that represented by Cronbach’s alpha coefficient. Validity was evaluated by content, convergent, divergent and contrast group comparison.
Results
The factor analysis identified a 24 items scale with 4 factors (avoidance coping, active and emotional coping, social support and religioun). A CFA demonstrated a good model fit. The Cronbach’s alpha coefficients for the whole scale and its subscales were acceptable ranged from 0.79 to 0.86 indicating good reliability. Content validity were supported by content validity index = 0.97. Convergent, divergent validity and contrast group comparison were evidenced by statistically significant correlations among subscales and the other instruments used.
Conclusions
The Indonesian version of Brief COPE may be a reliable and valid instrument to measure coping in advanced cancer patients and is ready for using in this population in Indonesian cultural context.
