Titre : Language disorder and retrospectively reported sexual abuse of girls: severity and disclosure Type de document : Texte imprimé et/ou numérique Auteurs : E. B. BROWNLIE, Auteur ; Eva GRAHAM, Auteur ; Lin BAO, Auteur ; Emiko KOYAMA, Auteur ; Joseph H. BEITCHMAN, Auteur Article en page(s) : p.1114-1121 Langues : Anglais (eng) Mots-clés : Language disorder sexual abuse trauma longitudinal studies Index. décimale : PER Périodiques Résumé : Background Despite emerging evidence for an association between communication disorders and maltreatment, little research has examined sexual abuse characteristics or disclosure experiences among individuals with language disorder (LD). Given that communication difficulties may constitute a barrier to disclosure, the disclosure experiences among individuals with and without communication difficulties may also differ. Methods Five-year-old children identified with a language and/or speech disorder from a nonclinical community sample and a control group were followed to adulthood in a prospective longitudinal study. At age 31, participants completed a behaviorally specific questionnaire on experiences of sexual abuse and questionnaires on disclosure experiences and social reactions to disclosure. Due to low endorsement of sexual victimization among male participants and low sample size, results are reported for women only and exclude nine participants with speech disorder without LD. Participation rates were 28 of 40 in the LD cohort and 45 of 51 controls. Sexual victimization severity was defined using an index combining five indicators (duration, invasiveness, relationship to perpetrator, coercive tactics used, and number of perpetrators). Subthreshold sexual victimization was defined as a single, noncontact incident with a perpetrator unknown to the child; experiences with greater severity were classified as child sexual abuse. Results Among women who reported sexual victimization by age 18, invasiveness and overall severity were greater in the LD cohort than in the control cohort. Women in the LD cohort (43%) were more likely than controls (16%) to report child sexual abuse, excluding subthreshold experiences. There were no differences between cohorts in probability of disclosure, latency to disclosure, or social reactions. Conclusions Women with a history of child LD in a nonclinical sample reported substantial child sexual abuse experiences. Implications for understanding associations between LD and mental health and for prevention and early intervention are discussed.

Titre : Models and determinants of vocabulary growth from kindergarten to adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Joseph H. BEITCHMAN, Auteur ; Hedy JIANG, Auteur ; Emiko KOYAMA, Auteur ; Carla J. JOHNSON, Auteur ; Michael ESCOBAR, Auteur ; Leslie ATKINSON, Auteur ; E. B. BROWNLIE, Auteur ; Ron VIDA, Auteur Année de publication : 2008 Article en page(s) : p.626-634 Langues : Anglais (eng) Mots-clés : Longitudinal-study speech/language-impairment speech-disordervocabulary-growth language-disorder Index. décimale : PER Périodiques Résumé : Background: Increasing evidence suggests that childhood language problems persist into early adulthood. Nevertheless, little is known about how individual and environmental characteristics influence the language growth of individuals identified with speech/language problems.
Method: Individual growth curve models were utilised to examine how speech/language impairment and environmental variables (socioeconomic status, family separation, and maternal factors) influence vocabulary development from age 5 to 25. Participants were taken from a community sample of children initially diagnosed with speech/language problems at age 5 and their sex- and age-matched controls.
Results: The language impaired group had significantly poorer receptive vocabulary than the speech impaired and control groups throughout the 20-year period. Family income was a significant predictor of vocabulary growth when considered separately, but ceased to be a predictor when language impairment status was taken into account. Maternal education and family separation were determinants of vocabulary at age 5, over and above language impairment status.
Conclusion: Language impairment is a significant risk factor for vocabulary development from childhood to adulthood. Individuals with speech impairment were less impaired on receptive vocabulary than individuals with language impairment. Further investigation into maternal and familial risk factors may provide targets for early intervention with children at risk for language impairment.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.01878.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=457
