Critical issues about scientific reproducibility have been raised about biomedical research, including the reliability of data and analyses within a given study. The case example in this article examined a reproducibility issue pertaining to the use of administrative data systems for evaluation of child maltreatment (CM) prevention, making use of a prevention study conducted over a decade ago that provided a unique opportunity. The place-randomization study, which randomized counties to condition, found that community-wide implementation of a parenting and family support intervention produced positive impact on county-wide rates for substantiated CM cases and out-of-home placements, documented through a state information system. The key consideration is whether and to what extent the administrative record data re-examined retroactively a decade later for the original study’s time period would yield comparable results to those based on data acquired at the time of the study. The results indicated that despite small changes over time, the same data patterns and statistical effects were reproducible for the two archival outcome variables. For substantiated CM, the reproduced analyses reflected higher effect sizes and a clear pattern of reduction as a function of intervention. For out-of-home placements, effect sizes were quite comparable to the original ones, reflecting preventive impact. Overall, this case study illustrated the verifiability of data reproducibility in the context of a population outcome evaluation, which underscores the importance of reliable population-prevalence measurement as an essential part of a comprehensive public health strategy aimed at the prevention of CM.  相似文献

Objective

The persecution of children as witches has received widespread reportage in the international mass media. In recent years, hundreds of children have been killed, maimed and abandoned across Africa based on individual and village-level accusations of witchcraft. Despite the media focus, to date, very little systematic study has investigated the phenomenon. In this case study, the persecution of child witches in Ghana is studied to explore the nature and patterns of witch hunts against children in the West African nation.

Methods

There are no reliable national data on child abuse related to witchcraft accusations in Ghana. For this study, 13 cases of child witch hunts appearing in the local media during 1994-2009 were analyzed. Case summaries were constructed for each incident to help identify the socio-demographic characteristics of assailants and victims, victim-offender relationships, the methods of attacks, the spatial characteristics, as well as the motivations for the attacks.

Results

Children branded as witches ranged in age from 1-month-old to 17-years-old, were primarily from poor backgrounds, and lived in rural areas of the country. Accusations of witchcraft and witch assaults were lodged by close family members often through the encouragement of, or in concert with Christian clergymen and fetish priests. Accused witches were physically brutalized, tortured, neglected, and in two cases, murdered. For school-aged children, imputations of witchcraft contributed to stigmatization in both the community and at school, resulting in dropping out. The most frequently expressed reason for persecution of the child was suspicion that the child had used witchcraft to cause the death or illness of family relations or someone in the community. Another reason was suspicion that the child was responsible for the business failure or financial difficulties of a perceived victim.

Conclusions

The results of this research are consistent with findings in the witchcraft literature suggesting that seemingly inexplicable illnesses, untimely deaths, and financial hardships tend to be the major causal forces generating witch hunts. Additional research is necessary to further shed light on child witch hunts in Ghana and other countries.

Practice implications

To reduce the incidence of such abuse, there is a need for increased advocacy and protections for children in the society. The government must also increase the penalties for child abuse. This will serve as a deterrent to potential offenders. Additionally, through public service campaigns, educating citizens about the causes and trajectories of diseases, will lead to a significant diminution of witchcraft accusations and the associated violence.  相似文献

Background

Emotional/psychological child maltreatment (ECM) is a major public health problem with serious consequences including emotional and behavioral problems. Nevertheless, ECM is an understudied area.

Objectives

The aims of this review are to identify measures of ECM and to evaluate their psychometric properties and utilities. We provide a summary of ECM measures that have been tested for their reliability and validity, evaluate the quality of these assessments and suggest directions for future research.

Methods

We searched PsycINFO and Medline databases from 2000 to 2010 in addition to a hand search of retrieved references; 2344 were identified and the abstracts reviewed independently by two authors to identify relevant articles. Using pre-established criteria, 144 of those articles were selected and reviewed in full to assess whether the instruments included a separate measure of ECM and its psychometric properties.

Results

Forty-five articles examining 33 measures met the inclusion criteria and were selected for further review. The majority of measures demonstrated acceptable reliability; fewer measures had evaluated one or more types of validity.

Conclusion

Both reliability and validity testing are required in order to establish more accurate measures of ECM.

Practice implications

Reliable and valid measures are necessary to enhance our limited knowledge about the distribution, determinants and consequences of ECM.  相似文献

BackgroundChild sexual abuse (CSA) rates have been declining since the 1990s (Dunne et al., 2003; Finkelhor & Jones, 2004, 2012; Jones et al., 2001). Discrepancies in contexts and measures complicate comparing CSA rates across jurisdictions and studies, and there is limited literature about trends in CSA in Canada.ObjectiveUsing data from the Ontario Incidence Study of Reported Child Abuse and Neglect (OIS), the only source of provincially aggregated data in Ontario, Canada, that describes child welfare investigations, this paper provides information on reported and investigated CSA over the past 20 years.Participants and settingThe OIS uses a file review methodology; information is collected directly from investigating child welfare workers.MethodsA sample of child welfare agencies is selected for the study, and data are collected over a three-month period. Weights are applied to produce annual provincial estimates.ResultsThe rates of investigated CSA in Ontario decreased between 1993 and 2013, from 5.20 (95% CI [3.94, 6.47]) to 1.81 (95% CI [0.97, 2.66]) children per 1000. During this time, the rate of all child maltreatment-related investigations doubled, from 21.41 (95% CI [18.38, 24.42]) to 53.32 ([29.61, 77.03]) children per 1000.ConclusionsUnlike other forms of child maltreatment, the incidence of investigated CSA in Ontario declined since 1993. Substantiation rates for CSA investigations decreased more dramatically than the rate of all CSA investigations, which could indicate a true decline in rate or an inability to accurately identify cases of CSA.  相似文献

BackgroundMental health problems in parents have been identified as a risk factor for child maltreatment. The perinatal period (from conception to 1 year) is a critical period but it is unclear whether perinatal mental health problems are also associated with increased risk.ObjectiveTo review evidence on perinatal mental health and risk of child maltreatment.MethodsSearches were conducted on six databases and 24 studies reported in 30 papers identified. Studies were conducted in seven countries, mainly the USA (n = 14). Sample sizes ranged from 48-14,893 and most examined mothers (n = 17). Studies were conducted in community (n = 17) or high-risk (n = 7) samples.ResultsThe majority of studies found a relationship between parental perinatal mental health problems and risk of child maltreatment, but inconsistent findings were observed between and within studies. The few studies that examined fathers (n = 6) all found a relationship between fathers’ mental health and risk of child maltreatment. Meta-analysis of 17 studies (n = 22,042) showed perinatal mental health problems increased risk of child maltreatment by OR 3.04 (95% CI 2.29–4.03). This relationship was moderated by type of sample, with larger effects for risk of child maltreatment in high-risk samples. The relationship was not moderated by type of mental illness, child maltreatment; methodological or measurement factors.ConclusionThe association between perinatal mental health and risk of child maltreatment is similar to that observed at other times during childhood. Methodological heterogeneity and inconsistent findings mean conclusions are tentative and need to be considered alongside other individual, family and social/cultural risk factors.  相似文献

BackgroundChild maltreatment by caregivers seem to make a significant contribution to general maltreatment rates. Interestingly, research assessing prevalence rates of maltreatment mainly focuses on individual components either in relation to different types of maltreatment or in relation to different types of institutions.ObjectiveThe current study assesses prevalence rates for child maltreatment by caregivers in hospitals, rehabilitation centers, facilities for the disabled, schools, Kindergartens, and after-school care or residential care.Participants and setting: In a cross-sectional survey, a representative sample of the German population above the age of 14 (N = 2,516) was selected in a random route approach. Participants were questioned retrospectively for the experience of physical, emotional and sexual abuse and neglect by caregivers in institutions.ResultsThe results demonstrate a relatively high rate of child maltreatment in German institutions. In detail, during inpatient stays in medical institutions, 19.0% of the participants reported to have experienced at least one type of maltreatment by nursing staff. Furthermore, 30.3% reported to have experienced at least one type of maltreatment by teachers during school life and 11.6% reported maltreatment by caregivers in care facilities. A significant number of participants reported multiple forms of maltreatment in all assessed institutions. Younger age of the respondents was associated with lower prevalence rates, which could be attributed to higher awareness for maltreatment in institutions nowadays.ConclusionsOur results demonstrate that child maltreatment by caregivers in institutions is a prevalent problem. A higher awareness for caregivers as potential perpetrators of maltreatment in institutions, including schools, medical institutions and care facilities, is needed in order to improve this alarming situation.  相似文献

Over the past 20 years, jurisdictions across the United States have implemented differential response (DR), which provides child protective services with the flexibility to tailor their response to reports of child abuse or neglect based on the level of risk. Given the widespread adoption of DR, there has been an increasing demand from policymakers, practitioners, and community stakeholders to build the evidence base for this innovative child welfare approach. This study was designed to answer the big questions regarding the effect of differential response on child welfare outcomes and costs using a randomized controlled trial in five Colorado counties. Specifically, the study examined the safety outcomes and costs of families who were randomly assigned to either a family assessment response (FAR) or an investigation response (IR). According to the regression results, there were no differences between the tracks on measures of system re-involvement. However, survival analysis findings indicate that FAR families were 18% less likely, over time, to have a high risk assessment after their initial accepted referral than were IR families. The cost study revealed no differences between the tracks on initial costs for caseworker contacts, services, and out-of-home placements. However, the results suggest that follow-up costs for IR cases were significantly higher (p < 0.001) than for FAR cases. The authors discuss policy and practice implications for jurisdictions considering DR.  相似文献

Despite the high rate of early parenthood among youth in foster care as well as the increased risk of child maltreatment among children whose adolescent parents have been neglected or abused, very little is known about child welfare services involvement among children whose parents were in foster care when they were born. This study uses administrative data from the Illinois Department of Children and Family Services (DCFS) to examine the occurrence of child abuse and neglect investigations, indicated reports and out of home care placements among the children of youth in foster. Thirty-nine percent of the children were the subject of at least one CPS investigation, 17 percent had at least one indicated report and 11 percent were placed in out of home care at least once before their 5th birthday. Cox proportional hazard models are also estimated to identify characteristics of parenting foster youth and their placement histories associated with the risk of child welfare services involvement. Implications of the findings for policy and practice are discussed.  相似文献

从产生“民工荒”的直接原因入手,分析其根本原因在于城乡分割的二元社会保障体制。而社会保障制度在这个问题上并未能体现出公平性来,从而影响了社会经济效率。在社会保障制度不能处理好公平与效率的关系时,它的保障功能也就无从体现。只有打破城乡分割的二元体制,社会保障制度真正做到“非歧视性原则”才能提高社会经济效率。  相似文献

Medical neglect is under-researched and the extent of the problem in Australia is unknown. We conducted a review of the referrals for medical neglect to the Child Protection Unit (CPU) at a tertiary children’s hospital in Sydney over a 5 years period, from 2011 to 2016, to determine what medical conditions are being referred, the reason for the medical neglect concern and whether cases are managed in line with American Academy of Pediatrics (AAP) guideline on medical neglect.61 cases of medical neglect were identified, constituting 4.1% of all referrals to the Child Protection Unit for physical abuse and neglect. There was a wide variety of medical conditions. Most were chronic medical conditions (87%). The top two medical conditions were chronic and complex multi-system disorders (37.7%) and endocrine disorders (18%). The majority of medical neglect were related to concerns that the caregivers were unwilling to follow medical advice (45.9%) or unable to provide necessary medical care (26.2%). In line with the AAP guideline on medical neglect, all cases were managed by addressing communication difficulties (100%) and resource issues were addressed in 80% of cases. A report to statutory child protection agencies was made in 50% of cases. Directly observed therapy and medical contracts were used in 30% and 26% of cases. We conclude that children with chronic medical conditions may be at risk of medical neglect. Communication difficulties were a factor in all cases. Statutory agency intervention is often required.  相似文献
