Incidence and Comorbidity of Reactive Attachment Disorder: Based on National Health Insurance Claims Data, 2010-2012 in Korea

A Systematic Review on Assessing Assessments: Unveiling Psychometric Properties of Instruments for Reactive Attachment Disorder and Disinhibited Social Engagement Disorder in Minors under Protective Measures

BACKGROUND

Reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED) manifest in individuals facing attachment system challenges, particularly observed in minors under protective measures. The lack of standardized tools for assessing these difficulties and uncertainty about the most effective instruments from a psychometric perspective prompted this study.

AIM

Using the COSMIN checklist, we systematically reviewed instruments assessing RAD, adhering to PRISMA.

METHODOLOGY

Examined tools included the Disturbance Attachment Interview, Preschool Age Psychiatric Assessment, Relationship Patterns Questionnaire, Assessment of RAD and DSED, Development and Well-Being Assessment, and Reactive Attachment Disorder Questionnaire.

RESULTS

Of the 10 articles analyzed, the results highlight a research emphasis on internal consistency and structural and construct validity, sidelining other properties.

CONCLUSION

Most articles review structural validity and internal consistency. These measures are satisfactory but insufficiently evaluated. It is necessary to evaluate these tools using other indicators such as cross-cultural validity, measurement error, or responsiveness in adolescents under protective measures.

Reactive Attachment Disorder and Its Relationship to Psychopathology: A Systematic Review

This study aimed to determine, through a systematic review, the relationship between Reactive Attachment Disorder (RAD) and the presence of psychopathology in children and adolescents, and to determine the existence of differences in terms of internalising and externalising psychological problems between the RAD group and groups with other disorders or with typical development. Following the PRISMA methodology, a search was carried out in the Web of Science, PubMed and Scopus databases. The search yielded 770 results, of which only 25 met the inclusion criteria. The results indicate a relationship between the presence of RAD and/or disinhibited social engagement disorder (DSED), with the presence of internalising and externalising problems. These difficulties are more present in children with RAD compared to children without personal difficulties, or children with DSED, children with autism, children with intellectual disabilities or children with hyperactivity. It can be concluded that the presence of RAD has negative consequences on the mental health of children and adolescents, with these being greater in the inhibited group than in the disinhibited group, and with respect to children with autism or hyperactivity.

Review of the Current Knowledge of Reactive Attachment Disorder

Reactive attachment disorder (RAD), classified under Trauma and Stressor Related Disorders in the DSM-5 manual, is a childhood psychiatric illness due to familial or social neglect or due to maltreatment. It is characterized by an inhibited and withdrawn social and emotional behavior toward an adult caregiver, typically before the age of 5. Neurobiological changes in patients with RAD have been shown to be substantially significant with features such as loss of grey matter volume and neurotransmitter deficiencies that not only impact the ability to form healthy attachments but also increase the risk of comorbidities such as depression and anxiety. Different theories, including the current mediation hypothesis and learning theory of attachment, showed childhood maltreatment from caregivers and desensitization toward deficiencies in social development in children from special education teachers to be key components in the development of RAD. Patients with RAD had an increased risk of developing psychiatric comorbidities, including learning disabilities and mood disorders. Institutionalized care and childhood maltreatment have a significant impact on the development of RAD. RAD is an underdiagnosed and underreported condition with significant repercussions that can severely impact the development of a child. By being able to raise awareness and promote further research into refining the diagnostic methodology, treatment protocols, and long-term follow-up, children afflicted with this condition may be able to develop better socio-emotional bonds and reduce the incidence of comorbidities such as depression and attention deficit hyperactivity disorder.

Classification, prevalence and integrated care for neurodevelopmental and child mental health disorders: A brief overview for paediatricians

‘Neurodevelopmental disorders’ comprise a group of congenital or acquired long-term conditions that are attributed to disturbance of the brain and or neuromuscular system and create functional limitations, including autism spectrum disorder, attention deficit/ hyperactivity disorder, tic disorder/ Tourette’s syndrome, developmental language disorders and intellectual disability. Cerebral palsy and epilepsy are often associated with these conditions within the broader framework of paediatric neurodisability. Co-occurrence with each other and with other mental health disorders including anxiety and mood disorders and behavioural disturbance is often the norm. Together these are referred to as neurodevelopmental, emotional, behavioural, and intellectual disorders (NDEBIDs) in this paper. Varying prevalence rates for NDEBID have been reported in developed countries, up to 15%, based on varying methodologies and definitions. NDEBIDs are commonly managed by either child health paediatricians or child/ adolescent mental health (CAMH) professionals, working within multidisciplinary teams alongside social care, education, allied healthcare practitioners and voluntary sector. Fragmented services are common problems for children and young people with multi-morbidity, and often complicated by sub-threshold diagnoses. Despite repeated reviews, limited consensus among clinicians about classification of the various NDEBIDs may hamper service improvement based upon research. The recently developed “Mental, Behavioural and Neurodevelopmental disorder” chapter of the International Classification of Diseases-11 offers a way forward. In this narrative review we search the extant literature and discussed a brief overview of the aetiology and prevalence of NDEBID, enumerate common problems associated with current classification systems and provide recommendations for a more integrated approach to the nosology and clinical care of these related conditions.

Clinical Study Using Healthcare Claims Database

The healthcare claims database is a database created using claims data accumulated while operating the government's health insurance system. The National Health Insurance Service (NHIS) provides benefits for health promotion, prevention, diagnosis, and disease and injury treatment, as well as for rehabilitation, birth, and death. Ninety-seven percent of the total population is enrolled in the NHIS; individuals pay a monthly insurance contribution to the system, and the NHIS pays a portion of the cost of reimbursement items to the medical institution when the subscriber receives medical services. In this process, the NHIS and Health Insurance Review Agency (HIRA) decide on payment, and claims data are documented items that medical institutions claim to these government agencies. The NHIS and HIRA have established a database to support policy and academic research, and they provide this database to researchers. Health claims data are representative of the nation, reflecting the actual medical environment. They also shorten the time and cost required for research and have several advantages as research data. However, studies should be conducted with an understanding of the limitations of claims data, a sufficient understanding of the characteristics of the Korean insurance system, and criteria for providing reimbursed services. Moreover, validating the healthcare claims database will facilitate more useful and reliable research.
