"Validation of a cyberbullying questionnaire as a screening tool for other forms of intimate-partner violence towards young women".

BACKGROUND

The use of electronic media is widespread among young people and is a potential tool for the perpetration of intimate-partner violence (IPV) towards women. The aim of this study is to validate two questions focused on harassment and control by electronic tools (HCE-2) as a screening tool for the detection of IPV in young women.

METHODS

The data source was the third Community of Madrid IPV survey in 2014. The screening tool consisted of two questions with five possible answers prepared by a group of experts. As the gold standard we used the definition of intimate partner violence based on a 26- question survey. The validity indices (with 95% confidence intervals) were compared between two age groups: 18-24 and 25-29 years.

RESULTS

Six hundred ninty-four women were sampled. The response rate was 68.7%, and 477 surveys were analyzed. The prevalence of IPV was 10.7% (95% CI: 8.2-13.8). HCE-2 was positive in 5.9% (95% CI: 4.1-8.4). The overall efficiency of the test was 93.5% (95% CI: 91.1-96.7), sensitivity 47.1% (95% CI: 33.7-60.8), specificity 99.1% (95% CI: 97.5-99.6), and positive predictive value 85.7% (95% CI: 67.1-94.6). The best validity indices of the questionnaire were observed in women aged 18 to 24 years: overall efficiency of the test 95.1% (95% CI: 92.6-97.7), sensitivity 62.5% (95% CI: 44.5-77.6), specificity 99.6% (95% CI: 97.0-99.9), and positive predictive value 95.2% (95% CI: 71.7-99.4).

CONCLUSIONS

The existing need to improve the detection of IPV in young women and the good validity indices observed here justify the recommendation of the HCE-2 questionnaire as a screening tool in young women.
