Cross-cultural adaptation and psychometric properties of the Chinese version of the Intermittent Self-Catheterization Questionnaire (ISC-Q).

Discriminant validity The dimension “Ease of Use” displayed no significant correlation with “Convenience” ( P > 0.001) but exhibited a highly significant positive correlation with “Discreetness” ( P < 0.001, r = 0.744). “Convenience” demonstrated a significant positive correlation with “Psychological Well-being” ( P < 0.001, r = 0.720) but showed no association with “Discreetness”. “Psychological Well-being” had no discernible relationship with either “Ease of Use” or “Discreetness” ( P > 0.001) (See Fig. 4 ).
