Dynamics of forensic interviews with suspected abuse victims who do not disclose abuse.

OBJECTIVES: The present study was designed to explore structural differences between forensic interviews in which children made allegations and those in which children did not make allegations. METHODOLOGY: Fifty forensic interviews of 4- to 13-year-old suspected victims of abuse who did not disclose abuse during the interview were compared with the same number of forensic interviews of alleged victims who made allegations of sexual or physical abuse. Only cases in which there was substantial reason to believe that abuse had taken place were included in the study. Audiotapes of the interviews were examined with a focus on interviewer utterances and children's responses during the pre-substantive rapport-building, episodic memory training, and 'getting the allegation' phases of the interviews, which all employed the NICHD Investigative Interview Guide. FINDINGS: Forensic interviews which yielded allegations of child abuse were characterized by quite different dynamics than interviews with children who did not make allegations. When interviewing non-disclosers, interviewers made less frequent use of free recall prompts and offered fewer supportive comments than when interviewing children who made allegations of abuse. Children who did not disclose abuse were somewhat uncooperative, offered fewer details, and gave more uninformative responses, even at the very beginning of the interview, before the interviewers focused on substantive issues and before the interviewers themselves began to behave differently. CONCLUSIONS: A premature focus on substantive issues may prevent children who are not responsive in the episodic memory training phase from disclosing abuse. Identifying reluctant disclosers and making more extensive efforts to build rapport before substantive issues are broached, or interviewing such children in more than one session, may help suspected victims disclose their experiences.

How does the legal system respond when children with learning difficulties are victimized?

OBJECTIVE: To understand how the Swedish legal system perceives and handles mentally handicapped children who may have been victimized. METHOD: Twenty-two judicial districts in Sweden provided complete files on 39 District Court cases (including the Appeals Court files on 17 of these cases) involving children with learning difficulties or other handicaps as alleged victims of abuse, threat and neglect. The children (25 girls and 14 boys) averaged 11.8 years of age when first allegedly victimized. Sexual abuse was the most frequently alleged crime (33 cases). Court transcripts, court files and expert assessments of the alleged victims' handicaps and their possible consequences were examined to elucidate the ways in which courts evaluated the credibility of the alleged victims. RESULTS: The children's reports of their victimization were expected to have the characteristics emphasized by proponents of Statement Reality Analysis (SRA) and Criterion Based Content Analysis (CBCA) in order to be deemed credible. Expert reports were seldom available or adequate. Because many reports were poorly written or prepared by experts who lacked the necessary skills, courts were left to rely on their own assumptions and knowledge when evaluating children's capacities and credibility. CONCLUSIONS: Children with learning difficulties or other handicaps were expected to provide the same sort of reports as other children. To minimize the risk that judgments may be based on inaccurate assumptions courts need to require more thorough assessments of children's limitations and their implications. Assessments by competent mental health professionals could inform and strengthen legal decision-making. A standardized procedure that included psycho-diagnostic instruments would allow courts to understand better the abilities, capacities, and behavior of specific handicapped children.

Effects of early and later family violence on children's behavior problems and depression: a longitudinal, multi-informant perspective.

OBJECTIVES: To examine the effects of different forms of family violence at two developmental stages by assessing a sample of 110 Israeli children, drawn from the case files of Israeli family service agencies, studied longitudinally in both middle childhood and adolescence. METHODS: Information about the children's adjustment was obtained from parents, teachers, and the children themselves when the children averaged 10.6 and 15.9 years of age using the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), Youth Self-Report (YSR), and Children's Depression Inventory (CDI). Information about the history of family violence was obtained from the mothers, fathers, children, and social workers. RESULTS: The results paint a mixed picture of the effects of family violence on children and adolescents. The relationship between concurrent behavior problems and abuse group varied by informant and study phase, although they were strongest when children were the informants. Predictions regarding the relationship between early abuse and later adjustment were only partially confirmed. Different informants did not agree about which groups of children were most adversely affected, there was little stability over time in the pattern of reported effects, and children were more likely than other informants to report levels of maladjustment that varied depending on recent or concurrent exposure to family violence. Many families changed their abuse status over time, and children who were new victims at follow-up had the most internalizing problems. Girls were found to be at more risk for internalizing and externalizing behavior problems than boys. CONCLUSIONS: Multiple informants are necessary to evaluate and assess the effects of family violence on children's behavior. Younger children may be more susceptible to the effects of family violence than older children, but problems manifest by some children may not carry over to adolescence. Changes in family and parenting practices, as well as in children's capacity to appraise and cope with family violence may help mitigate the adverse effects of family violence.

Trends in children's disclosure of abuse in Israel: a national study.

OBJECTIVE: To identify characteristics of suspected child abuse victims that are associated with disclosure and nondisclosure during formal investigations. METHODOLOGY: The database included all suspected cases of physical and sexual abuse investigated in the state of Israel between 1998 and 2002. All investigative interviews were conducted using a single standardized protocol, the National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. FINDINGS: Overall, 65% of the 26,446 children made allegations when interviewed, but rates of disclosure were greater in the case of sexual (71%) than physical (61%) abuse. Children of all ages were less likely to disclose/allege abuse when a parent was the suspected perpetrator. Rates of disclosure/allegation increased as children grew older, with 50% of the 3- to 6-year-olds, 67% of the 7- to 10-year-olds, and 74% of the 11- to 14-year-olds disclosing abuse when questioned. CONCLUSIONS: Although most interviews of suspected victims yielded allegations, such rates of disclosure varied systematically depending on the nature of the alleged offences, the relationship between alleged victims and suspected perpetrators, and the age of the suspected victims. The findings obtained in this large and unselected data set confirm patterns previously reported in smaller and quite selective samples, most of them obtained in the United States.

Adolescents' perceptions of attachments to their mothers and fathers in families with histories of domestic violence: a longitudinal perspective.

OBJECTIVE: The effects of both childhood and teenage experiences of domestic violence on adolescent-parent attachments were examined. METHOD: Israeli adolescents (M = 15.9 years) who were either victims of physical abuse, witnesses of physical spouse abuse, victims and witnesses of abuse, or neither victims nor witnesses of abuse were questioned about attachments to their parents using the Inventory of Parent and Peer Attachment [IPPA; Armsden, G. C., & Greenberg, M. T. (1987). The inventory of parent and peer attachment: Individual differences and their relationship to psychological well-being in adolescence. Journal of Youth and Adolescence, 16, 427-454]. FINDINGS: Abuse status 5 years earlier was unrelated to the adolescents' current perceptions of their attachments whereas current abuse status predicted the adolescents' perceptions of attachment to their mothers. Adolescents who were victims of physical abuse reported weaker attachments to their parents than adolescents who were not abused or who had solely witnessed interparental physical abuse. Attachments to mothers were weaker whether or not mothers were the perpetrators of abuse. CONCLUSIONS: These findings suggest that victimization adversely affects children's perceptions of relationships with their parents, but that changes in the exposure to family violence are associated with changes in relationships with parents. These findings suggest that intervention can have positive effects on parent-child relationships despite violent histories.

Mothers' and fathers' behaviors toward their 3- to 4-month-old infants in lower, middle, and upper socioeconomic African American families.

African American mothers' and fathers' availability, caregiving, and social behaviors toward their infants in and around their homes were examined. Twenty lower, 21 middle, and 21 upper socioeconomic families and their 3- to 4-month-old infants were observed for 4 3-hr blocks between 8:00 a.m. and 8:00 p.m. on 4 different weekdays. With increasing economic resources, children's exposure to multiple caregivers and nonresident fathers declined. Mothers were more available to infants than fathers were, regardless of socioeconomic status. Mothers fed infants more than fathers did, whereas fathers vocalized more and displayed more affection to infants than mothers did when they were examined in proportion to caregiver presence. Mothers and fathers interacted with male and female infants quite similarly, although, in the upper socioeconomic families, fathers of daughters were more available than fathers of sons. Fathers and mothers in the different socioeconomic groups held, displayed affection to, and soothed their infants differently.

Developmental differences in the function and use of anatomical dolls during interviews with alleged sexual abuse victims.

The impact of anatomical dolls on reports provided by 3- to 12-year-old alleged sexual abuse victims (N = 178) was examined. Children produced as many details in response to open-ended invitations with and without the dolls. In response to directive questions, the 3- to 6-year-olds were more likely to re-enact behaviorally than to report verbally, whereas the 7- to 12-year-olds produced more verbal details than enactments when using the dolls. With the dolls, the younger children were more likely than the older children to play suggestively and to contradict details provided without the dolls, whereas the older children were more likely to provide details that were consistent. Children in both age groups produced proportionally more fantastic details with the dolls than without the dolls.

Interviewing youthful suspects in alleged sex crimes: a descriptive analysis.

OBJECTIVE: To introduce and evaluate a structured interview protocol designed for investigative interviews of youthful alleged perpetrators of child sexual abuse. METHOD: Seventy-two alleged perpetrators ranging from 9 to 14 years of age (M = 12 years) were interviewed by 1 of 13 experienced youth investigators, employed by the Israeli Ministry of Labour and Social Affairs, about incidents that had been reported by alleged victims. All interviews were conducted as part of the investigators' regular work and followed the structured interview guide appended to this article. RESULTS: Interviewers questioned older and younger children similarly, but addressed fewer invitations, directive questions, and option-posing prompts to suspects who denied the allegations than to those who partially or fully admitted them. The total number of details provided by the suspects did not vary depending on their age or whether or not they fully or partially admitted the allegations. In both cases, more information was elicited using invitations rather than suggestive or option-posing prompts. CONCLUSION: Contrary to expectations, suspects who at least partially admitted their involvement provided considerable amounts of information and were very responsive to free recall prompts, although interviewers used more risky (potentially error-inducing) prompts when interviewing suspects rather than alleged victims.

Using a human figure drawing to elicit information from alleged victims of child sexual abuse.

Ninety 4- to 13-year-old alleged victims of sexual abuse were interviewed by police officers using the National Institute of Child Health and Human Development (NICHD) investigative interview protocol, following which they were shown a human figure drawing and asked a series of questions. The drawing and associated questions elicited an average of 86 new forensically relevant details. They were especially productive with 4- to 7-year-olds, who provided an average of 95 additional details (27% of their total) after the drawing was introduced despite having previously "exhausted" their memories. Information elicited using the drawing may be less accurate, however, because recognition memory prompts predominated, so such drawings should only be introduced late in investigative interviews.

The child maltreatment log: a computer-based program for describing research samples.

The Child Maltreatment Log (CML) is a computer-based program designed to record information about children's maltreatment experiences and associated life events. Addressing concerns posed by scientific panels and grant review panels, the CML was designed to improve upon existing instruments to facilitate collaboration among researchers interested in maltreatment. The CML encourages researchers to collect information from multiple sources and informants concerning children's maltreatment experiences. Rather than classifying types of maltreatment a priori, the CML allows researchers to describe children's experiences using objective descriptors pertaining to potential acts of abuse, potential perpetrators, frequency, onset, consequential injuries, and treatment. The CML can be downloaded by interested agencies and groups without charge.

Differences between accounts provided by witnesses and alleged victims of child sexual abuse.

OBJECTIVES: To determine whether child witnesses of sexual abuse were more or less informative about the alleged incidents than alleged victims when interviewed similarly. METHOD: Twenty-six alleged victims of child sexual abuse (aged 5 to 14 years; M=9.8 years) and 26 children who had witnessed but not experienced similar events were interviewed by experienced youth investigators about the alleged abuse. Children in the two groups were matched with respect to their age, relationships with the alleged perpetrator, and seriousness of the alleged offenses. All children were interviewed using the NICHD investigative interview protocol. RESULTS: Witnesses and victims provided similar amounts of information about the incidents of abuse. Interviewers used more open-ended invitations and elicited more information using open-ended prompts from witnesses than from victims, whereas they used more risky (including suggestive) prompts when interviewing victims. DISCUSSION: These results confirm that young children can be informative witnesses about events that they have either experienced or witnessed.

The effects of interviewer gender and child gender on the informativeness of alleged child sexual abuse victims in forensic interviews.

Most students of forensic interviews have focused on the interrogatory techniques used to elicit information from alleged child abuse victims. We asked how the gender of the interviewer and the gender of the child affected this process. Forensic investigators in three countries used either the NICHD structured interview protocol or local standard interview practices to interview 672 alleged victims who ranged in age from 4 to 14 years. Analyses of the interviews showed significant effects of gender on both the interviewers' behavior and the amount of information provided by children. Female interviewers asked boys more invitations, as well as absolutely and proportionally more suggestive questions, than they did girls, whereas male interviewers interviewed boys and girls similarly. Children's responses varied depending on their gender and age, the gender of the interviewer, and the type of question asked. Girls of all ages provided more information in response to directive questions posed by female rather than male interviewers whereas boys did not respond differently to male and female interviewers. The oldest girls provided more information in response to option-posing questions posed by male interviewers. More information was provided by the younger children in response to suggestive prompts from interviewers of the opposite gender. The gender-of-interviewer effects were attenuated in protocol-guided interviews.

Age differences in young children's responses to open-ended invitations in the course of forensic interviews.

To elucidate age differences in responses to free-recall prompts (i.e., invitations and cued invitations) and focused recognition prompts (i.e., option-posing and suggestive utterances), the authors examined 130 forensic interviews of 4- to 8-year-old alleged victims of sexual abuse. There were age differences in the total number of details elicited as well as in the number of details elicited using each of the different types of prompts, especially invitations. More details were elicited from older than from younger children in response to all types of prompts, but there were no age differences in the proportion of details (about 50%) elicited using invitations. Cued invitations elicited 18% of the total details, and the number of details elicited using cued invitations increased with age. Action-based cues consistently elicited more details than other types of cues.

Developmental issues in relocation cases involving young children: when, whether, and how?

Many divorced parents seek the court's permission each year to move their children to a new location away from their other parents. Such moves stress and often disrupt psychologically important parent-child relationships, and this may in turn have adverse consequences for children. This article discusses the development of attachment relationships in infants and toddlers and the ways in which relocation is likely to affect young children of different ages; recent trends in judicial decisions regarding relocation; factors to consider when deciding whether or not to permit relocation; ways of promoting long-distance relationships between young children and their non-moving parents; and implications for legal policy and clinical practice.

Marital conflict and boys' peer relationships: the mediating role of mother-son emotional reciprocity.

This study examined the role of mother-son emotional reciprocity in connections between marital conflict and the quality of boys' peer relationships. Parents from 84 intact families with preadolescent boys reported on the level of conflict in their marital relationship. Observations of mother-son interaction were coded for emotional reciprocity, and assessments of boys' peer relationships were obtained from both teachers and classmates. No direct connection between marital conflict and boys' peer relationships was observed. Rather, marital conflict affected boys' social competence indirectly, through its effect on the emotions expressed between mother and son. The findings support the proposal that emotional processes play an important role in connections between marital conflict and children's peer relationships and suggest that family emotional expressiveness deserves greater attention in both research and intervention.

Emergence and constructvalidation of the big five factors in early childhood: a longitudinal analysis of their ontogeny in Sweden.

Researchers have shown that the five major dimensions of personality (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) and two additional factors (irritability and positive activity) are evident from adolescence. This study attempted to replicate and extend these results in a longitudinal study of 102 Swedish children, followed from 2.3 to 15.2 years of age. Item analyses revealed consistently reliable irritability, conscientiousness, and positive activity factors, whereas the internal reliability of the extraversion, agreeableness, neuroticism, and openness to experience factors increased over time. Irritability and positive activity were not independent of the other factors. Scores on most of the personality factors were fairly stable over time. Over time, children became less extraverted, more agreeable, and more conscientious. Neuroticism and openness to experience increased in Phase III, although openness then decreased in Phase V. Validity of the original factors was demonstrated by correlations with independent assessments of the children's cognitive performance and adjustment to school.

Shared care: establishing a balance between home and child care settings.

The onset of regular nonparental care for infants and toddlers has complex psychobiological and behavioral effects on their functioning both at home and in child care centers. Maladaptive behavior on the part of children who spend many hours in child care may reflect not the direct effects of nonparental care but the inability of parents to buffer the enhanced levels of stress experienced in child care. Successful adaptation demands careful equilibration of the contrasting limitations and benefits of the two environments, with parental care characterized by stress reduction and emotional regulation and providers' care characterized by emphasis on cognitive stimulation and behavioral regulation.

Transition to child care: associations with infant-mother attachment, infant negative emotion, and cortisol elevations.

Seventy 15-month-old infants were studied at home before starting child care, during adaptation (mothers present) and separation (first 9 days without mothers) phases, and 5 months later. Security of infant-mother attachment was assessed before and 3 months after child care began. In the separation phase, salivary cortisol rose over the first 60 min following the mothers' departures to levels that were 75% to 100% higher than at home. Compared with insecure infants, secure infants had markedly lower cortisol levels during the adaptation phase and higher fuss and cry levels during the separation phase, and their fuss and cry levels were significantly correlated with their cortisol levels. Attachments remained secure or became secure if mothers spent more days adapting their children to child care.
