The single available observational study found that, at 7 days post colposcopy, women with a colposcopic impression of high-grade disease who had been managed by immediate LLETZ reported lower anxiety and higher relief and perception of control than those managed by biopsy and selective recall (Orbell et al, 2004; Balasubramani et al, 2007).
We identified two conceptually and empirically distinct and internally consistent summary scales measuring Sen-Sei-Ro consumers' perceptions of its effects, Relief of Symptoms and Functional Well-being (Cronbach's alpha: Relief of Symptoms, α =.74; Functional Well-Being, α =.91).
