Use of a Linguistically Appropriate Decision Aid for Cervical Cancer Screening of South Asian Ethnic Minority Women in Hong Kong: A Pilot Randomised Controlled Trial.

Abstract

Decision aids have been shown to be effective in assisting the decision-making process in healthcare settings. This study aimed to examine the feasibility and acceptability of a linguistically appropriate printed decision aid for cervical cancer screening in South Asian women and to preliminarily estimate its effects on decisional conflicts, clarity of values, risk perception, the screening decision and screening uptake. This was a pilot randomised controlled trial. Forty-eight South Asian women aged 25 to 64years were recruited and allocated to either the intervention group or control group. The participants in the intervention group read a linguistically appropriate printed decision aid. All of the participants in the intervention group agreed that the decision aid was useful in aiding their decision-making. These participants showed significantly greater improvement in decisional conflicts, clarity of values and risk perceptions than those in the control group (all p < 0.05). The screening uptake rate was significantly higher in the intervention group than in the control group (p < 0.001). The decision aid was feasible and acceptable among South Asian women, and it resulted in reduced decisional conflict and increased screening uptake compared with usual care. To improve the convenience of using decision aids, they could be developed in various forms, such as printed and mobile application forms, to meet individual requirements. The trial was registered at the Chinese Clinical Trial Registry on 23 October 2021 (ChiCTR2100052225).
