Assessment of Testifying Ability in Preschool Children: CAPALIST

Purpose: Interviews to obtain statements in judicial procedures need to be adapted to the witnesses' abilities to testify. Moreover, knowing the cognitive abilities involved in testifying provides relevant criteria to assess statement credibility. As age or intelligence quotient is not enough to estimate these capabilities, an instrument to evaluate witnesses' specific abilities to testify is needed. The present paper validates CAPALIST, a procedure that considers relevant capabilities when assessing the testimony given by children. Methods: This study analyzed, by means of an invariant measurement approach (Rasch model), four scales included in CAPALIST: language, memory, contextual information, and social thinking. In addition, gender and age differences were analyzed in 83 children [45 males and 38 females; M _age = 4.3 years, SD = 0.74, range (3.06-5.11)] from three courses in early childhood education. Results: The four scales do not severely violate the requirements of the model. The principal component analysis of the residuals indicates that the four scales are one dimensional and that the assumption of local independence was not violated. Differential item functioning of the scales associated with gender was not detected. A significant effect of the school year was obtained, with an increase in ability in successive courses. The percentage of children who presented severe misfit responses with the model was low. In addition, the number of items with a severe misfit was also low. Conclusion: An acceptable performance of CAPALIST is demonstrated for most of the scales, although items with a severe misfit must be replaced, and more difficult items have to be included in some scales of the revised version of the instrument. CAPALIST is a promising procedure to assess the abilities of children to testify in order to adapt interviews and to evaluate their statements correctly.

Prevalence and sequelae of self-reported and other-reported sexual abuse in adults with intellectual disability

BACKGROUND

Sexual victimisation is an important problem that affects millions of people around the world, especially those with some kind of disability. The aim of this study was to determine the prevalence of self-reported and documented sexual abuse in people with mild or moderate intellectual disability and to analyse the sequelae that such experiences can have on their psychosocial health.

METHODS

The sample consisted of 360 adults (50% men and 50% women) between 18 and 55 years of age (M = 39.87; standard deviation = 10.55).

RESULTS

The prevalence of sexual abuse is 6.10% when it is self-reported (9.4% in women and 2.8% in men) and 28.6% when it is reported by professionals (27.8% in women and 29.4% in men). People who self-report cases of abuse present poorer quality of life, more negative attitudes towards sex and a lower capacity to identify situations that entail a risk of sexual abuse. Individuals who have suffered documented cases of abuse are more likely to present encopresis, social isolation, self-harm and a higher number of suicide attempts.

CONCLUSIONS

Our results evidence the need to have access to all sources of information so as to be able to obtain prevalence figures that match the real situation and to perform a proper analysis of the sequelae.
