'I just wanted someone to ask me': when to ask (about child sexual abuse)

A systematic review of the measurement properties of self-report screening tools to detect risk or exposure to child sexual abuse for children under 12

Child sexual abuse (CSA) is a substantial public health issue that is challenging to measure epidemiologically due to the "pact of silence" among those involved. Validated tools could contribute to early recognition or risk detection for CSA. We aimed to systematically assess self-report tools' measurement properties and methodological quality that detect risk or exposure to CSA for children under twelve. The search strategy, selection criteria, data extraction, data analysis, and synthesis followed the COSMIN methodology for systematic reviews (2018). PROSPERO 2021 registration CRD42021278465. MEDLINE, COCHRANE, EMBASE, CINAHL, SCOPUS, and ERIC were searched until August 2021, with an updated search on September 23, 2021, and unlimited by language. The inclusion criteria were: to assess risk or exposure to CSA under twelve years old by objective items and self-report tools; sexual violence risk or exposure in the domestic context; the application context should include health facilities (such as hospital emergency rooms, outpatient clinics, pediatric wards, psychology centers, social services), education (such as schools) and community; no language or date restriction. The exclusion criteria were: non-self-report tools studies, comprehensive articles, comments, editorials, expert opinions, and studies of projective techniques. The COSMIN risk of bias checklist was used to evaluate the methodological quality of the included studies. Feasibility aspects were assessed. This study had no funding source; 29 studies describing eight tools met eligibility criteria. No single instrument reported all nine measurement properties outlined by the COSMIN methodology. The strength of the evidence was moderate to high for six out of eight instruments. ICAST-C and JVQ were the tools that obtained the highest number of rated measurement properties and strength of evidence.

Reliability of the Sexual Knowledge Picture Instrument: a potential diagnostic instrument for sexual abuse in young children

OBJECTIVE

To determine the intra-rater and inter-rater reliability of the Sexual Knowledge Picture Instrument (SKPI), a potential diagnostic instrument for young suspected victims of sexual abuse containing three scoring forms, that is, verbal responses, non-verbal reactions and red flags.

DESIGN

Video-recorded SKPI interviews with children with and without suspicion of child sexual abuse were observed and scored by two trained, independent raters. The second rater repeated the assessment 6 weeks after initial rating to evaluate for intra-rater reliability.

SUBJECTS

78 children aged 3-9 years old were included in the study. 39 of those included had known suspicion of sexual abuse and the other 39 had no suspicion.

MAIN OUTCOME MEASURES

Intra-rater and inter-rater reliability of the scores per study group and in the total sample were assessed by Cohen's kappa and percentage of agreement (POA).

RESULTS

The median intra-rater Cohen's kappa exceeded 0.90 and the POA exceeded 95 for all three forms in both study groups, except for the red flag form (median Cohen's kappa 0.54 and POA 87 in the suspected group, and 0.84 and 92, respectively, in the total sample). For the verbal scoring form the median inter-rater Cohen's kappa and POA were 1.00 and 100, respectively, in both groups. For the non-verbal form the median inter-rater kappa and POA were 0.37 and 97, respectively, in the suspected group, and 0.47 and 100, respectively, in the control group. For the red flag form, they were 0.37 and 76, respectively, in the suspected group and 0.42 and 77, respectively, in the control group.

CONCLUSION

The reliability of the SKPI verbal form was sufficient, but there is room for improvement in the non-verbal and red flag scoring forms. These forms may be improved by adjusting the manual and improving rater training.
