Disadvantaged neighborhoods and the spatial overlap of substantiated and unsubstantiated child maltreatment referrals

2019

Abstract Background Considerable debate exists on whether the substantiation decision is a reliable measure for rates of maltreatment. Studies have shown that risks among children victims of maltreatment versus children investigated but unsubstantiated are similar. Objective This paper aims to respond to two research questions: (1) Do most child maltreatment referrals, substantiated and unsubstantiated, come from the same neighborhoods? (2) Do substantiated and unsubstantiated referrals share the same neighborhood risk factors? Participants and settings We used geocoded data from substantiated (n = 1799) and unsubstantiated (n = 1638) child maltreatment referrals in Valencia, Spain (2004–20…

Validity of adult retrospective reports of adverse childhood experiences: review of the evidence

2004

Background:  Influential studies have cast doubt on the validity of retrospective reports by adults of their own adverse experiences in childhood. Accordingly, many researchers view retrospective reports with scepticism. Method:  A computer-based search, supplemented by hand searches, was used to identify studies reported between 1980 and 2001 in which there was a quantified assessment of the validity of retrospective recall of sexual abuse, physical abuse, physical/emotional neglect or family discord, using samples of at least 40. Validity was assessed by means of comparisons with contemporaneous, prospectively obtained, court or clinic or research records; by agreement between retrospecti…

Reporting heterogeneity in health: an extended latent class approach

2012

This article explores how individual socio-economic characteristics affect unobserved heterogeneity in self-reporting behaviour and health production using a multivariate finite mixture model. Results show a positive relationship between objective and subjective observable health indicators and true health and support the existence of self-reporting bias related to socio-economic characteristics and individual life styles.

Association of childhood leukaemia with factors related to the immune system

1999

The childhood peak of common acute lymphoblastic leukaemia has been proposed as being a rare response to delayed exposure to a common infection. In this context, factors related to the child’s immune system are of special interest. Information on such factors was obtained in a recent German case-control study comprising more than 1000 children with acute leukaemia. Neither being the first-born child, nor a short duration of breastfeeding, indicators of a deficit in viral contacts during infancy or the number of infectious diseases, were significant risk factors. We observed a strong association with fewer routine immunizations with a 3.2-fold increase for those children getting less than fo…
