Previous issue date: 2017-01-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Maltreatment is the main form of violence in childhood and considered a global public health
problem. The impact of this phenomenon is known through a body of solid evidence, mainly
on its neurobiological, cognitive and psychopathological consequences. Among the most
studied are the deregulation of the Hypothalamic-Hypophyseal-Adrenal axis and the
concentrations of the hormone cortisol, which can generate several deleterious effects for the
victims. It is also known that many subtypes of maltreatment occur simultaneously,
characterizing exposure to multiple victimizations. In addition, other forms of victimization,
such as peer and community violence, are highly prevalent in several countries. However, few
studies emphasize the relevance of assessing different types of victimization through valid
instruments. Similarly, few studies investigates the role and influence of different methods of
cortisol measurement in children exposed to maltreatment. In this sense, the objective of this
dissertation was to investigate the most used methodologies for measuring cortisol in children
victims of maltreatment and to make the transcultural adaptation of the Juvenile Victimization
Questionnaire (JVQ R2). For this, a theoretical study of systematic review of methods of
measurement of cortisol in abused children and an empiric of cross-cultural adaptation and the
beginning of the psychometric examination of the JVQ-R2 were carried out. The review
found a homogeneity of methods restricted to saliva samples in studies of the last 5 years.
Important gaps have been discussed regarding long-term cortisol measurement. The
adaptation of the JVQ R2 has been completed adequately, as well as preliminary
examinations of psychometric properties. The full validation of the instrument with all its
versions for youth and caregivers is already under way. / Maus tratos s?o as principais formas de viol?ncia na inf?ncia e considerados um
problema de sa?de p?blica mundial. O impacto desse fen?meno ? conhecido atrav?s de um
corpo de evid?ncias s?lidas, principalmente, sobre as suas consequ?ncias neurobiol?gicas,
cognitivas e psicopatol?gicas. Entre as mais estudadas, est? a desregula??o do eixo
Hipotal?mico-Hipofisi?rio-Adrenal e das concentra??es do horm?nio cortisol, que podem
gerar diversos efeitos delet?rios para o organismo das v?timas. Sabe-se tamb?m que muitos
subtipos de maus tratos ocorrem simultaneamente, caracterizando a exposi??o a m?ltiplas
vitimiza??es. Al?m disso, outras formas de vitimiza??o, como viol?ncia entre pares e
comunit?ria s?o de alta preval?ncia em diversos pa?ses. No entanto, poucos estudos
enfatizam a relev?ncia da avalia??o de diferentes tipos de vitimiza??o, atrav?s de
instrumentos v?lidos. Da mesma forma, ? escassa a literatura que investiga o papel e
influ?ncia de diferentes m?todos de mensura??o de cortisol em crian?as expostas a maus
tratos. Nesse sentido, o objetivo da presente disserta??o foi investigar quais as metodologias
mais empregadas para mensurar cortisol em crian?as v?timas de maus tratos e fazer a
adapta??o transcultural Juvenile Victimization Questionnaire (JVQ R2). Para tal, foi
realizado um estudo te?rico de revis?o sistem?tica sobre m?todos de medida de cortisol em
crian?as maltratadas e um emp?rico de adapta??o transcultural e do in?cio do exame
psicom?trico do JVQ-R2. A revis?o encontrou uma homogeneidade de m?todos restritos a
amostras de saliva em estudos dos ?ltimos 5 anos. Foram discutidas lacunas importantes
sobre a mensura??o de cortisol a longo prazo. A adapta??o do JVQ R2 foi conclu?da de
forma adequada, assim como os exames preliminares das propriedades psicom?tricas. A
valida??o integral do instrumento com todas as suas vers?es para jovens e cuidadores j?
encontra-se em andamento.
