Survivors of sexual abuse: clinical,lifestyle and reproductive consequences

BACKGROUND: In recent years, an increase in the prevalence of sexual abuse of women has been reported in Canada and elsewhere. However, there are few empirical data on the extent of the problem in Canadian aboriginal populations. The authors investigated the presence of a reported history of sexual abuse and other health determinants in a sample of women attending a community health centre with a substantial aboriginal population. This allowed determination of whether reported sexual abuse and its associated demographic and health-related effects were different for aboriginal and non-aboriginal women. METHODS: A sample of 1696 women was selected from women attending a community health centre in a predominantly low-income inner-city area of Winnipeg for a cross-sectional survey designed to study the association between sexual behavior and cervical infections. The survey was conducted between November 1992 and March 1995 and involved a clinical examination, laboratory tests and an interviewer-administered questionnaire. A substudy was conducted among 1003 women who were asked 2 questions about sexual abuse. RESULTS: The overall response rate for the main study was 87%. Of the 1003 women who were asked the questions about sexual abuse, 843 (84.0%) responded. Among the respondents, 368 (43.6%) were aboriginal. Overall, 308 (36.5%) of the respondents reported having been sexually abused, 74.0% of the incidents having occurred during childhood. The prevalence was higher among aboriginal women than among non-aboriginal women (44.8% v. 30.1%, p < 0.001). Women who had been sexually abused were younger when they first had sexual intercourse, they had multiple partners, and they had a history of sexually transmitted diseases. In addition, non-aboriginal women who had been sexually abused were more likely than those who had not been abused to have been separated or divorced, unemployed and multiparous and to have used an intrauterine device rather than oral contraceptives. Aboriginal women who had been sexually abused were more likely than those who had not been abused to have been separated or divorced, unemployed and multiparous and to have used an intrauterine device rather than oral contraceptives. Aboriginal women who had been sexually abused were more likely than those who had not been abused to have had abnormal Papanicolaou smears. The proportion of smokers was higher among the abused women than among the non-abused women in both ethnic groups. INTERPRETATION: A history of sexual abuse was associated with other clinical, lifestyle and reproductive factors. This suggests that sexual abuse may be associated with subsequent health behaviors, beyond specific physical and psychosocial disorders. Aboriginal and non-aboriginal women who have suffered sexual abuse showed substantial differences in their subsequent health and health-related behaviours.     

Abuse History is related to Autonomic Regulation to Mild Exercise and Psychological Wellbeing

We investigated the potential impact of abuse history on autonomic regulation and psychological wellbeing in a sample of women who reported a history of abuse without Post Traumatic Stress Disorder. To measure autonomic regulation, heart rate data was collected before and after the participant rode a stationary bike for one mile. We found that abuse history was associated with less vagal regulation of the heart (i.e., respiratory sinus arrhythmia) and an inability to rapidly re-engage vagal regulation immediately following mild exercise to support a calm physiological state. These findings are consistent with clinical impressions that abused individuals may have a lower threshold to express fight/flight behaviors in response to stress and have difficulty shifting from mobilization to calmness. We also found that abuse history was related to psychological wellbeing. Women with an abuse history reported a greater use of dysfunctional coping methods and lower self-concept. Further, analyses indicated that there was a cumulative effect, whereby women who reported more recent abuse reported using more dysfunctional coping methods, having more mood disturbance, and lower self-concept. The findings underscore the importance of evaluating both the psychological and physiological effects of trauma, even in the absence of a diagnosis of PTSD.     

A 30‐year Follow‐up of the Effects of Child Abuse and Neglect on Obesity in Adulthood

Childhood maltreatment has been implicated as a risk factor for adult obesity. We describe the first prospective assessment of adult obesity in individuals with documented histories of childhood physical and sexual abuse and neglect and a matched comparison group in a 30‐year follow‐up. Using a prospective cohort design, children with court substantiated cases of physical and sexual abuse and neglect (ages 0–11 years) from a Midwest county during 1967–1971 (n = 410) were matched with children without histories of abuse or neglect on age, sex, race/ethnicity and approximate family social class (n = 303) and followed up and assessed at mean age 41. Outcome measures include BMI and obesity assessed in 2003–2004 as part of a medical status examination and interview. Childhood physical abuse predicted significantly higher BMI scores in adulthood (β = 0.14, P < 0.05), even controlling for demographic characteristics, cigarette smoking, and alcohol consumption (β = 0.16, P < 0.01). Childhood sexual abuse (β = 0.07, not significant) and neglect (β = 0.02, not significant) were not significant predictors of adult BMI scores. These results demonstrate the long‐term impact of childhood physical abuse on weight into adulthood and suggest that physically abused children may be at risk for other adverse health outcomes associated with increased weight. Health professionals need to understand this risk for physically abused children and researchers should identify and evaluate strategies for effective interventions.     

Detecting Nestmate Recognition Patterns in the Fission-Performing Ant <Emphasis Type="Italic">Aphaenogaster senilis</Emphasis>: A Comparison of Different Indices

In this paper, we compare three indices for nestmate recognition behaviors in the ant Aphaenogaster senilis within and among colonies and populations: the classical Aggression Index, a multidimensional Principal Component Analysis (PCA) Behavioral Index incorporating all observed behaviors, and a Chemical Profile Index for cuticular hydrocarbon composition. With these indices, we quantified nestmate recognition behaviors between workers from a parent nest and between those from independent colonies. The PCA Behavioral Index performed as well as or better than the classical Aggression Index in distinguishing small differences in nestmate recognition. Correlation analysis of the PCA Behavioral Index with the Chemical Profile Index may assist in identifying the occurrence of colony fissions. The PCA Behavioral Index correlated strongly with the Chemical Profile Index, suggesting that hydrocarbon profiling may be used as an alternative to nestmate recognition assays. This correlation also suggests that nestmate recognition in A. senilis is a graded response rather than a threshold one.     

Childhood physical abuse in outpatients with psychosomatic symptoms

Background

In Japan and Asia, few studies have been done of physical and sexual abuse. This study was aimed to determine whether a history of childhood physical abuse is associated with anxiety, depression and self-injurious behavior in outpatients with psychosomatic symptoms.

Methods

We divided 564 consecutive new outpatients at the Department of Psychosomatic Medicine of Kyushu University Hospital into two groups: a physically abused group and a non-abused group. Psychological test scores and the prevalence of self-injurious behavior were compared between the two groups.

Results

A history of childhood physical abuse was reported by patients with depressive disorders(12.7%), anxiety disorders(16.7%), eating disorders (16.3%), pain disorders (10.8%), irritable bowel syndrome (12.5%), and functional dyspepsia(7.5%). In both the patients with depressive disorders and those with anxiety disorders, STAI-I (state anxiety) and STAI-II (trait anxiety) were higher in the abused group than in the non-abused group (p < 0.05).In the patients with depressive disorders, the abused group was younger than the non-abused group (p < 0.05). The prevalence of self-injurious behavior of the patients with depressive disorders, anxiety disorders and pain disorders was higher in the abused groups than in the non-abused groups (p < 0.005).

Conclusion

A history of childhood physical abuse is associated with psychological distress such as anxiety, depression and self-injurious behavior in outpatients with psychosomatic symptoms. It is important for physicians to consider the history of abuse in the primary care of these patients.

     

Behavioral evaluation and demographic information in the assessment of aggressiveness in shelter dogs

Behavioral evaluations of 2017 shelter dogs were used for identifying dogs with aggressive tendencies and for predicting post-adoption behavior problems. Associations between failure of the behavioral evaluation and demographic factors (age, breed, and sex) and the dog's behavioral history, evaluated by logistic regression, were highly significant (P < 0.0005), except for “old” dogs (age > 72 months). Dogs that failed the behavior evaluation were not placed for adoption; therefore it was not possible to study prospectively the capability of behavioral evaluation to predict future aggressiveness in these dogs. Instead we developed tests for classifying dogs as aggressive or not aggressive based on their demographic factors and behavior evaluation outcomes. The results were compared retrospectively to the dogs’ known behavioral histories, which were obtained at intake to the shelter. This allowed estimation of the sensitivity, specificity, and accuracy of the classification tests. The most significant postdictor (i.e., “retrospective predictor”) of aggressiveness was failure of the behavioral evaluation (odds ratio 11.83, P < 0.0005). Among dogs that passed the behavioral evaluation, classification as “unsocial” by the behavioral evaluation was associated with nonaggressive behavior problems reported at 6-month follow-up (P = 0.005), and classification as “borderline” was associated with return to the shelter for aggressive behavior (P = 0.028). Behavioral evaluations reduced the rate of returns of adopted dogs from 19% in the year prior to their institution to 14% (P = 0.001) during the 2-year study period. Returns for aggression were reduced from 5% to 3.5% (P = 0.05), with many fewer incidents of serious aggression. The majority of dogs (86%) that failed the behavioral evaluation failed multiple component tests, indicating general aggressive tendencies in these dogs. Together with demographic information and behavioral history, behavioral evaluations can help to improve decisions regarding the disposition of shelter dogs.     

Structural Pathways between Child Abuse,Poor Mental Health Outcomes and Male-Perpetrated Intimate Partner Violence (IPV)

Background

Violent trauma exposures, including child abuse, are risk factors for PTSD and comorbid mental health disorders. Child abuse experiences of men exacerbate adult male-perpetrated intimate partner violence (IPV). The relationship between child abuse, poor mental health and IPV perpetration is complex but research among the general population is lacking. This study describes the relationship and pathways between history of child abuse exposure and male-perpetrated IPV while exploring the potentially mediating effect of poor mental health.

Methods

We analysed data from a randomly selected, two-stage clustered, cross-sectional household survey conducted with 416 adult men in Gauteng Province of South Africa. We used multinomial regression modelling to identify associated factors and Structural Equation Modelling (SEM) to test the primary hypothesis that poor mental health (defined as abusing alcohol or having PTSD or depressive symptoms) mediates the relationship between child abuse and IPV perpetration.

Results

Eighty eight percent of men were physically abused, 55% were neglected, 63% were emotionally abused and 20% were sexually abused at least once in their childhood. Twenty four percent of men had PTSD symptoms, 24% had depressive symptoms and 36% binge drank. Fifty six percent of men physically abused and 31% sexually abused partners at least once in their lifetime. Twenty two percent of men had one episode and 40% had repeat episodes of IPV perpetration. PTSD symptomatology risk increased with severity of child trauma and other trauma. PTSD severity increased the risk for binge drinking. Child trauma, other trauma and PTSD symptomatology increased the severity of depressive symptoms. PTSD symptomatology was comorbid with alcohol abuse and depressive symptoms. Child trauma, having worked in the year before the survey, other trauma and PTSD increased the risk of repeat episodes of IPV perpetration. Highly equitable gender attitudes were protective against single and repeat episodes of IPV perpetration. There was a direct path between the history of child trauma and IPV perpetration and three other indirect paths showing the mediating effects of PTSD, other trauma and gender attitudes.

Conclusions

Child trauma is a risk factor for both poor mental health and male-perpetrated IPV among men in Gauteng. Male-perpetrated IPV in these settings should be explained through a combination of the Trauma, Feminist, and Intergenerational Transmission of Family Violence theories. Prevention interventions for male- perpetrated IPV in South Africa need to incorporate strategies and therapies to address poor mental health conditions.     

Medical problems of adults who were sexually abused in childhood.

The aim of the study was to see whether adults who had been sexually abused in childhood were vulnerable to physical symptoms and therefore investigation and intervention. The case histories of seven patients who were aged 22-39, were under the care of three consultant psychiatrists, had experienced childhood sexual abuse, and had a history of medical or surgical intervention were surveyed. The patients had had a mean of 18 contacts with non-psychiatric consultant teams and a mean of eight operations, with a high rate (66-70%) of normal findings. They had experienced many somatic symptoms, which led to investigations and interventions in the specialties of gynaecology, obstetrics, gastroenterology, urology, rheumatology, haematology, orthopaedics, neurology, and neuropsychiatry. The history of childhood sexual abuse was recognised only in the later stages of this medical and surgical intervention. The possibility of childhood sexual abuse should be considered earlier in such cases to prevent further unnecessary intervention.     

Child sexual abuse--children and families referred to a treatment project and the effects of intervention.

The characteristics of a series of 274 families who were referred to a sexual abuse treatment programme were analysed. Information was obtained on 411 abused children and 362 non-abused children. Different forms of sexual abuse were noted, with 77% of girls and 23% of boys affected. Boys tended to be abused at a younger age, more severely, and for longer periods than girls. There was a predominance of lower social class groups among the parents, and a wide variety of family structures, with reasonable stability over time. Ninety six per cent of perpetrators were men, and biological and step-parents predominated. Contributing factors in both the family history and the current perpetrators and their wives included sexual abuse, violence, chaotic families, marital problems, sexual difficulties, alcoholism, and subnormality. Follow up of 120 families, 180 victims, and 226 siblings showed that prosecution occurred in 60% of cases, with a high percentage of perpetrators being imprisoned. Treatment was offered to 87% of families, but because the treatment programme was in the early stages of development a variable number of children and parents were offered family treatment or treatment in groups for parents and children separately. There was an improvement in the victim''s circumstances in 61% of cases, and a noticeable reduction in "sexualised" and general emotional difficulties among victims, but there was reabuse rate of 16%. Protection of children was achieved through changes of family attitude and changes in family structure including divorce and separation: 14% of victims were rehabilitated to both parents, 33% to mothers only, and 26% to new families or other residences. Consensus in the family that abuse had occurred was seen as an important factor in determining which children could be rehabilitated with both their parents, with their mothers only, or with new families; which families could be offered or accepted treatment; and whether positive changes in the family occurred.     

Enrichment strategies for laboratory animals from the viewpoint of clinical veterinary behavioral medicine: emphasis on cats on dogs

Behavioral wellness has become a recent focus for the care of laboratory animals, farm and zoo animals, and pets. Behavioral enrichment issues for these groups are more similar than dissimilar, and each group can learn from the other. The emphasis on overall enhancement for laboratory dogs and cats in this review includes an emphasis on behavioral enrichment. Understanding the range of behaviors, behavioral choices, and cognitive stimulation that cats and dogs exhibit under non-laboratory conditions can increase the ability of investigators to predict which enrichments are likely to be the most successful in the laboratory. Many of the enrichment strategies described are surprisingly straightforward and inexpensive to implement.     

Growth variation in common marmoset monkeys (Callithrix jacchus) fed a purified diet: relation to care-giving and weaning behaviors

Significant relations were observed between select infant-care and weaning behaviors and growth in body weight in common marmoset monkeys (Callithrix jacchus). The patterns of these relations suggest that earlier occurrence of developmental milestones, such as cessation of transport (being off carriers) and weaning to solid food, were associated with slower growth during the subsequent period. In contrast, more frequent nursing bouts during the period in which weaning was initiated were associated with higher growth rates. In the case of being off carriers, these effects did not carry over to older ages, suggesting that any deficits in growth were temporary. In the case of earlier, more frequent consumption of solid food, there was some suggestion that there were longer-term effects, followed by catch-up growth. The knee-to-heel length of subjects was not related to the measured behaviors. There was no relation between early weaning to solid food and leanness at day 75, suggesting that, although this behavior was affecting overall weight, it did not affect relative gains of fat versus lean mass. There were, however, significant correlations between cessation of transport or frequency of nursing bouts during the weaning period and leanness, with earlier cessation of transport and less frequent nursing associated with leaner infants, after weaning. Our results differed from those of a previous study that found a relation between linear growth and abuse in this species, with abuse defined as physical injury by other members of the group. We found no differences in growth between abused and nonabused infants. However, abused infants had lower birth weight.     

Child abuse: The limits of sociobiology

A review of five population based studies indicates that rates of child abuse tend to be highest among young male children from poor families. Children from very large families, children from families with a history of marital disruption, and defective children are also at a high risk of abuse. Perpetrators are more apt to be fathers or stepparents than would be expected on the basis of their representation in families of abused children. Biological mothers are least apt to abuse their children.Although these data are consistent with an evolutionary model of child abuse, many of these findings are also consistent with alternative (especially economic) models for abuse. An attempt is made to develop testable predictions for child abuse that are consistent with evolutionary theory and inconsistent with more conventional models.     

In-Kennel Behavior Predicts Length of Stay in Shelter Dogs

Previous empirical evaluations of training programs aimed at improving dog adoption rates assume that dogs exhibiting certain behaviors are more adoptable. However, no systematic data are available to indicate that the spontaneous behavior of shelter dogs has an effect on adopter preference. The aim of the present study was to determine whether any behaviors that dogs exhibit spontaneously in the presence of potential adopters were associated with the dogs'' length of stay in the shelter. A sample of 289 dogs was videotaped for 1 min daily throughout their stay at a county shelter. To account for differences in adopter behavior, experimenters varied from solitary passive observers to pairs of interactive observers. Dogs behaved more attentively to active observers. To account for adopter preference for morphology, dogs were divided into “morphologically preferred” and “non-preferred” groups. Morphologically preferred dogs were small, long coated, ratters, herders, and lap dogs. No theoretically significant differences in behavior were observed between the two different dog morphologies. When accounting for morphological preference, three behaviors were found to have a significant effect on length of stay in all dogs: leaning or rubbing on the enclosure wall (increased median length of stay by 30 days), facing away from the front of the enclosure (increased by 15 days), and standing (increased by 7 days). When combinations of behaviors were assessed, back and forth motion was found to predict a longer stay (increased by 24 days). No consistent behavioral changes were observed due to time spent at the shelter. These findings will allow shelters to focus behavioral modification efforts only on behaviors likely to influence adopters'' choices.     

Is there a link between cot death and child abuse?

Forty five babies delivered in Oxford obstetric units who subsequently died unexpectedly in infancy were compared with 134 controls matched for maternal age, social class, parity, and year of birth to see whether five factors identified in an earlier study as predictive of subsequent child abuse would also predict the sudden infant death syndrome. Epidemiological findings had suggested certain similarities between the two events. In contrast with babies who were abused, four of the five factors did not distinguish between babies who died suddenly and unexpectedly and their controls, but there was a slight increase in the proportion of mothers of babies who died suddenly and unexpectedly for whom nursing staff thought that support and advice on feeding the baby were needed. Factors predictive of child abuse did not predict sudden infant death in this study.     

The Relationship between Child Maltreatment and Emotion Recognition

Child abuse and neglect affect the development of social cognition in children and inhibit social adjustment. The purpose of this study was to compare the ability to identify the emotional states of others between abused and non-abused children. The participants, 129 children (44 abused and 85 non-abused children), completed a children’s version of the Reading the Mind in the Eyes Test (RMET). Results showed that the mean accuracy rate on the RMET for abused children was significantly lower than the rate of the non-abused children. In addition, the accuracy rates for positive emotion items (e.g., hoping, interested, happy) were significantly lower for the abused children, but negative emotion and neutral items were not different across the groups. This study found a negative relationship between child abuse and the ability to understand others’ emotions, especially positive emotions.     

Detecting and managing elder abuse: challenges in primary care

OBJECTIVE: To determine family physicians'' perceptions of barriers and strategies in the effective detection and appropriate management of abused elderly people. DESIGN: Questionnaire survey; the protocol included an advance notification letter and 3 follow-up mailings. SETTING: Regional Municipality of Hamilton-Wentworth, Ont. PARTICIPANTS: All active nonspecialist physicians who reported seeing elderly patients in their practices were eligible for inclusion. Fifty health service organization (HSO) physicians were randomly selected from among those listed with the HSO Mental Health Program, and 200 fee-for-service physicians were randomly selected from the Canadian Medical Directory. Of the 189 eligible physicians 122 returned completed questionnaires, a response rate of 65%. OUTCOME MEASURES: Physicians'' ratings of the importance of potential barriers in assisting older people experiencing abuse and of the usefulness of strategies for dealing with elder abuse. RESULTS: Physicians identified the following barriers as fairly or very important: denial of abuse, resistance to intervention, not knowing where to call for help, lack of protocols to assess and respond to abuse, lack of guidelines about confidentiality, fear of reprisal, and lack of knowledge of the prevalence and definition of elder abuse. Strategies deemed to be helpful included a single agency to call, a directory of services, a list of resource people, an educational package, guidelines for detection and management, reimbursement for time spent on legal matters, continuing education, revision of fee structure and a central library of resources on elder abuse. CONCLUSION: Although the physicians perceived numerous barriers to their detection and management of elder abuse, they identified many strategies that could be implemented at a local level. Preparation of an algorithm to help physicians is the next phase of this work.     

Abuse of elderly people by their carers.

OBJECTIVE--To assess the prevalence of abuse of elderly people by their carers and the characteristics of abusers and the abused. DESIGN--Information on abuse and risk factors was collected over six months from carers and patients. Risk factors were identified in the abused group and compared with those in a non-abused control group. SETTING--Carers were interviewed at home; patients were examined in the wards of Putney and Barnes geriatric hospitals, London. SUBJECTS--All patients referred from any source for respite care to the geriatric services over a six month period and their carers. MAIN OUTCOME MEASURES--Amount of physical and verbal abuse or neglect. Quantification of risk factors and correlation with the presence or absence of abuse. RESULTS--45% Of carers openly admitted to some form of abuse. Few patients admitted abuse. The most significant risk factor for physical abuse was alcohol consumption by the carer (p less than 0.001). Other significant risk factors were a poor pre-morbid relationship and previous abuse over many years. Abuse was often reciprocated and was associated with social dysfunction in many patients. Service delivery, respite care, and level of mental and physical disability were not significantly associated with abuse. CONCLUSION--The high level of abuse found in elderly patients in respite care was particularly associated with alcohol abuse and long term relationships of poor quality, which are difficult to change. Even with increased provision of services, care in the community may not be the best solution for these people.     

Testing the Validity and Reliability of the Shame Questionnaire among Sexually Abused Girls in Zambia

Purpose

The aim of the current study is to test the validity and reliability of the Shame Questionnaire among traumatized girls in Lusaka, Zambia.

Methods

The Shame Questionnaire was validated through both classical test and item response theory methods. Internal reliability, criterion validity and construct validity were examined among a sample of 325 female children living in Zambia. Sub-analyses were conducted to examine differences in construct validity among girls who reported sexual abuse and girls who did not.

Results

All girls in the sample were sexually abused, but only 61.5% endorsed or reported that sexual abuse had occurred. Internal consistency was very good among the sample with alpha = .87. Criterion validity was demonstrated through a significant difference of mean Shame Questionnaire scores between girls who experienced 0–1 trauma events and more than one traumatic event, with higher mean Shame Questionnaire scores among girls who had more than one traumatic event (p = .004 for 0–1 compared to 2 and 3 events and p = .016 for 0–1 compared to 4+ events). Girls who reported a history of witnessing or experiencing physical abuse had a significantly higher mean Shame Questionnaire score than girls who did not report a history of witnessing or experiencing physical abuse (p<.0001). There was no significant difference in mean Shame Questionnaire score between girls who reported a sexual abuse history and girls who did not. Exploratory factor analysis indicated a two-factor model of the Shame Questionnaire, with an experience of shame dimension and an active outcomes of shame dimension. Item response theory analysis indicated adequate overall item fit. Results also indicate potential differences in construct validity between girls who did and did not endorse sexual abuse.

Conclusions

This study suggests the general utility of the Shame Questionnaire among Zambian girls and demonstrates the need for more psychometric studies in low and middle income countries.     

Kin recognition by paternal half-siblings in captive Papio cynocephalus

Our objective in this study was to evaluate whether a group of paternally related, subadult baboons (Papio cynocephalus) would preferentially interact with kin or nonkin when they had been raised apart from kin other than their mothers. Subjects and their mothers were removed from the breeding group and placed in alternate housing within 24 h after birth to ensure that the subjects would not have a social history with either their sire or their half-siblings. At 90 days of age, the 23 subjects were separated from their mothers and assigned to a peer–peer social group. Behavioral performance was measured using focal animal sampling techniques and 12 molecular behavioral criteria. Analyses of the data indicate that in dyadic interactions kin did not interact more frequently than nonkin in performance of affiliative, sociosexual, and agonistic behaviors. The hypothesis that baboons recognize kin in the absence of maternal associations was not supported by the data; moreover, we suggest that social learning and social history are the most likely mechanisms for kin recognition.
