Introduction and hypothesis
We aimed to translate and culturally adapt the Pelvic Organ Prolapse Symptom Score (POP-SS) into Amharic and evaluate its psychometric properties.
Methods
We followed an intercultural adaptation procedure to translate and adapt the POP-SS. One hundred and eighty-six women with POP symptoms completed the Amharic POP-SS and Prolapse Quality of Life (P-QoL) questionnaires. All women were examined using a simplified Pelvic Organ Prolapse Quantification (SPOP-Q) system and were divided into four groups based on the POP-Q scores as stage 1, 2, 3, and 4. Internal consistency and test–retest reliability were determined using Cronbach’s alpha and the intraclass correlation coefficient (ICC), respectively. Criterion validity was assessed against the SPOP-Q stage and the P-QoL scale. Furthermore, we tested construct validity using exploratory factor analysis.
Results
The POP-SS score was successfully translated and achieved good content validity. It had high internal consistency (Cronbach’s alpha = 0.86) and test–retest reliability (ICC = 0.81; p < 0.001). There was a statistically significant difference among four groups of stages in POP-SS score. and women with stage 3 had the highest median score (Kruskal-Wallis test; p < 0.05). The POP-SS score was also significantly correlated with the P-QoL score (Spearman’s correlation coefficient = 0.28, p < 0.001). The exploratory factor analysis identified two factors, namely, physical symptoms and evacuation symptoms.
Conclusions
The POP-SS scale was successfully translated to Amharic and appears reliable and valid for women with symptoms of POP. However, further studies are needed to evaluate its responsiveness.
