Youth self-report of physical and sexual abuse: a latent class analysis.

OBJECTIVE: To determine if meaningful groups of at-risk pre-adolescent youth could be identified based on their self-report of physical and sexual abuse histories. METHODS: Youth participating in a consortium of ongoing longitudinal studies were interviewed using an audio-computer assisted self-interview (A-CASI) when they were approximately 12 years of age to obtain information about their perceived experiences of physical (18 items) and sexual (12 items) abuse. In addition, Child Protective Service records were reviewed and the taxonomy developed for defining maltreatment characteristics (Barnett, Manly, & Cicchetti, 1993) was applied. A total of 795 youth completed the age 12 interview and had their records reviewed during the period from birth to the time of their age 12 interview. A latent variable modeling approach, specifically latent class analysis (LCA), was used to generate profiles of youth based on their endorsements of the physical and sexual abuse items. These profiles were then compared to CPS reports of physical or sexual abuse to determine their validity. RESULTS: The LCA identified 4 interpretable classes or groups of pre-adolescent youth. Based on the pattern of responses to specific items the classes were identified as follows: (1) no physical or sexual abuse; (2) high physical abuse/low sexual abuse; (3) no physical abuse/moderate sexual abuse; and (4) high physical and sexual abuse. Follow-up analyses indicated that the odds of a CPS report for Classes 2, 3, and 4 compared to Class 1 were significantly greater (2.21, 2.55, and 5.10, respectively). CONCLUSION: The latent variable modeling approach allowed for the identification of meaningful groups of youth that accounted for both the occurrence of multiple types of abuse as well as differing severities associated with each type. It is suggested that this methodological approach may be most useful in future efforts to identify the antecedents and consequences of maltreatment. PRACTICE IMPLICATIONS: The results of the present study not only have implications for future research efforts, but also suggest that in practice, youth at-risk for maltreatment may be reliable and valid reporters of their physical and sexual abuse experiences.

Sexual intercourse among adolescents maltreated before age 12: a prospective investigation.

OBJECTIVE: To examine whether child maltreatment (physical, emotional, and sexual abuse, and neglect) predicts adolescent sexual intercourse; whether associations between maltreatment and sexual intercourse are explained by children's emotional distress, and whether relations among maltreatment, emotional distress, and sexual intercourse differ according to gender. METHODS: The Longitudinal Studies of Child Abuse and Neglect was a multisite, longitudinal investigation. Participants ranged from at-risk to substantiated maltreatment. Maltreatment history was assessed through Child Protective Service records and youth self-report at age 12. Youth reported emotional distress by using the Trauma Symptom Checklist at the age of 12 years and sexual intercourse at ages 14 and 16. Logistic and multiple regressions, adjusting for gender, race, and site, were used to test whether maltreatment predicts sexual intercourse, the explanatory effects of emotional distress, and gender differences. RESULTS: At ages 14 and 16, maltreatment rates were 79% and 81%, respectively, and sexual initiation rates were 21% and 51%. Maltreatment (all types) significantly predicted sexual intercourse. Maltreated youth reported significantly more emotional distress than non-maltreated youth; emotional distress mediated the relationship between maltreatment and intercourse by 14, but not 16. At 14, boys reported higher rates of sexual intercourse than girls and the association between physical abuse and sexual intercourse was not significant for boys. CONCLUSIONS: Maltreatment (regardless of type) predicts sexual intercourse by 14 and 16. Emotional distress explains the relationship by 14. By 16, other factors likely contribute to intercourse. Maltreated children are at risk for early initiation of sexual intercourse and sexually active adolescents should be evaluated for possible maltreatment.

Describing maltreatment: do child protective service reports and research definitions agree?

OBJECTIVE: The National Research Council identified inadequate research definitions for abuse and neglect as barriers to research in child maltreatment. We examine the concordance between child protective services (CPS) classifications of maltreatment type with the determinations of type from two research coding systems. We contrast the two coding systems and the CPS classification, in their ability to predict subsequent difficulties in the psychological functioning of maltreated children at age 8. METHOD: The sample included 545 children who were enrolled in Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) with a report of child maltreatment, had data collected at approximately 4 and 8 years of age, and had a lifetime review of CPS records to age 8. CPS Maltreatment reports were coded using LONGSCAN's modification of the Maltreatment Classification System (MMCS) and the Second National Incidence Study maltreatment coding system (NIS-2). The first analyses used reports as the unit of analysis to examine agreement between CPS and research determinations of allegation type. Validation analyses examined outcomes for each type of maltreatment experienced after age 4 under each coding system using the Child Behavior Checklist (CBCL), Trauma Symptom Checklist-Alternative form, and the Vineland Screener as the measures of outcome. Control variables were the CBCL and Battelle Developmental Screener, measured at age 4. RESULTS: There were a total of 1980 reports of maltreatment for 545 study children although only 1593 CPS reports specified at least one type of maltreatment. There were differences between the type of maltreatment recorded in child protective service records and the conclusions reached by either research classification system. CPS classifications were most discordant with the research systems for emotional abuse and neglect. Nearly 10% of physical and sexual abuse reports, as determined by the MMCS, were classified as neglect by the child protective service agencies. The NIS-2 system and the MMCS had very high Kappa statistics for agreement for physical and sexual abuse. The validity of the research definitions for physical and sexual abuse was demonstrated in models predicting children's functioning at age 8. Prediction of child functioning was significantly but modestly improved in several domains compared to the CPS classifications. CONCLUSION: Both research classification systems moderately improved on the prediction of the adverse effects of maltreatment compared to the characterization of a maltreatment exposure as recorded by CPS.
