Cultural adaptation, translation and validation of the ISPCAN Child Abuse Screening Tool - Retrospective Version (ICAST-R) for young adults in Sri Lanka

The aim of the present study was to adapt and validate the ISPCAN child abuse screening tool retrospective version (ICAST-R) in Sri Lanka with a view to investigating the experiences of physical, sexual and emotional abuse during childhood. The adaptation was performed using qualitative research methods with young adults, parents, teachers, and a multidisciplinary group of experts. The translation to Sinhala (the local Sri Lankan dialect) was carried out by a nominal group technique. A multidisciplinary team of experts assessed the Sinhala ICAST-R (SICAST-R) for its content validity. Moreover, acceptability, reliability and construct validity were determined by conducting a validation study among 200 schooling young adults. The principal component analysis (PCA) technique was used to assess the construct validity. Response rates for each item were taken as evidence of acceptability. The internal consistency was assessed by Cronbach's alpha, and test-retest reliability after two weeks was assessed using Cohen's kappa coefficient. The adaptation of ICAST-R included the introduction of an objective manner by which to measure severity of abuse and the inclusion of a set of questions regarding help-seeking behavior following physical and emotional abusive experiences. The SICAST-R showed adequate content validity and high acceptability, with response rates ranging from 90.3% to 99.5%. The minimum Cohen's kappa coefficient was 0.76, indicating good test-retest reliability. The internal consistency (Cronbach's alpha) for the total tool was 0.708, with the three constructs being 0.398, 0.844 and 0.637 for physical, sexual and emotional abuse, respectively. The PCA demonstrated good reproducibility for sexual and emotional abuse with the hypothesized structure. Overall, the SICAST-R showed adequate validity for the assessment of experiences of physical, sexual and emotional abuse during childhood among Sri Lankan young adults.
