Abstract:
PURPOSE: Cervical cancer can be prevented by regular cervical screening. Embarrassment has been reported as one important barrier to cervical screening uptake. The absence of appropriate instrumentation, however, has limited our understanding of the links between embarrassment and health care outcomes. The purpose of this study was to evaluate psychometric attributes of the uterine cervical cancer screening embarrassment questionnaire. METHODS: A convenience sample for field study was recruited from four gynecological clinics in Gyeongju, Korea. Within a cross-sectional descriptive design, 339 women who had cervical screening completed self-administered measures of embarrassment including a visual analogue, general medical embarrassment, dispositional embarrassment, and Pap smear related negative emotion. RESULTS: Rasch analysis of items demonstrated the evidence of one-dimensional construct and good 7-point rating scales functioning. Factor analysis revealed that uterine cervical cancer screening embarrassment was comprised of two domains-bodily manifestations and perceiving an undesirable social face. Construct validity was demonstrated by a high subscale-to-subscale correlation. Convergent and discriminant validity was evidenced by significant correlations with a 100 mm VAS scale, general medical embarrassment, and Pap smear related negative emotion. Known-group validity was established by comparing women with high versus low trait embarrassment. Both two sub-scales and overall scale demonstrated good internal reliability. CONCLUSION: The Uterine uterine cervical cancer screening questionnaire is a reliable and valid instrument suited to assessing the manifestations of embarrassment during screening. The use of instrument can be extended to understand the client's embarrassment undergoing health examinations which require the exposure of their private parts.
