Background

The cervical cancer (CC) incidence rate is increasing among young women aged <50 years despite early screening is proven effective. Electronic health (e-health) has great potential for disseminating health education.

Methods

This study validated a newly developed e-health tool “SeDAR^®” and assessed its usability via evaluations by health experts (HE), media experts (ME), and women. The SeDAR^® content was developed based on protection motivation theory (PMT) using the nominal group technique and in-depth interviews that involved HE and women, respectively. Content validation was performed among the HE (n = 12) and ME (n = 5) using the content validation index (CVI) to identify their agreement. Subsequently, the Video Engagement Scale (VES^®) was used to validate SeDAR^® among women of different ethnicities (n = 11) to achieve ecological validity. The experts and women also commented on the presentation of the video.

Results

The validation yielded a good CVI among the HE (scale-level CVI-average [SCVI/Ave] = 0.986; scale-level CVI-universal agreement [SCVI/UA] = 0.900) and ME (SCVI/Ave = 0.979, SCVI/UA = 0.897). The highest VES^® score [mean (±SD) = 92.90(±3.46)] proved the ecological validity of SeDAR^®. The experts’ feedback established that SeDAR^® conveyed a clear message about awareness of performing CC screening and was suitable for public viewing. The women considered SeDAR^® easy to understand, and it advised early exposure for early CC screening.

Conclusions

SeDAR^® was valid and could constitute an important e-health tool to improve motivation and uptake of CC screening.
