A cohort study is a particular form of longitudinal study that samples a cohort, performing a cross-section at intervals through time. It is a type of panel study where the individuals in the panel share a common characteristic.
Co-sleeping or bed sharing is a practice in which babies and young children sleep close to one or both parents, as opposed to in a separate room. Co-sleeping individuals sleep in sensory proximity to one another, where the individual senses the presence of others. This sensory proximity can either be triggered by touch, smell, taste, or noise. Therefore, the individuals can be a few centimeters away or on the other side of the room and still have an effect on the other. It is standard practice in many parts of the world, and is practiced by a significant minority in countries where cribs are also used.
Reactive attachment disorder (RAD) is described in clinical literature as a severe disorder that can affect children, although these issues do occasionally persist into adulthood. RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating socially in most contexts. It can take the form of a persistent failure to initiate or respond to most social interactions in a developmentally appropriate way—known as the "inhibited form". In the DSM-5, the "disinhibited form" is considered a separate diagnosis named "disinhibited attachment disorder".
Grandparents, individually known as grandmother and grandfather, are the parents of a person's father or mother – paternal or maternal. Every sexually-reproducing living organism who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, thirty-two genetic great-great-great-grandparents, sixty-four genetic great-great-great-great grandparents, etc. In the history of modern humanity, around 30,000 years ago, the number of modern humans who lived to be a grandparent increased. It is not known for certain what spurred this increase in longevity, but it is generally believed that a key consequence of three generations being alive together was the preservation of information which could otherwise have been lost; an example of this important information might have been where to find water in times of drought.
An attachment theory is a psychological, evolutionary, and ethological theory concerning relationships between humans. The most important tenet is that young children need to develop a relationship with at least one primary caregiver for normal social and emotional development. The theory was formulated by psychiatrist and psychoanalyst John Bowlby (1907–1990).
Edward John Mostyn Bowlby, CBE, FBA, FRCP, FRCPsych was a British psychiatrist, and psychoanalyst, notable for his interest in child development and for his pioneering work in attachment theory. A Review of General Psychology survey, published in 2002, ranked Bowlby as the 49th most cited psychologist of the 20th century.
A form of child abuse, child neglect is an act of caregivers that results in depriving a child of their basic needs, such as the failure to provide adequate supervision, health care, clothing, or housing, as well as other physical, emotional, social, educational, and safety needs. All societies have established that there are necessary behaviours a caregiver must provide for a child to develop physically, socially, and emotionally. Causes of neglect may result from several parenting problems including mental disorders, unplanned pregnancy, substance use disorder, unemployment, over employment, domestic violence, and, in special cases, poverty.
Child psychopathology refers to the scientific study of mental disorders in children and adolescents. Oppositional defiant disorder, attention-deficit hyperactivity disorder, and autism spectrum disorder are examples of psychopathology that are typically first diagnosed during childhood. Mental health providers who work with children and adolescents are informed by research in developmental psychology, clinical child psychology, and family systems. Lists of child and adult mental disorders can be found in the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), published by the World Health Organization (WHO) and in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA). In addition, the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood is used in assessing mental health and developmental disorders in children up to age five.
Early childhood caries (ECC), formerly known as nursing bottle caries, baby bottle tooth decay, night bottle mouth and night bottle caries, is a disease that affects teeth in children aged between birth and 71 months. ECC is characterized by the presence of 1 or more decayed, missing, or filled tooth surfaces in any primary tooth. ECC has been shown to be a very common, transmissible bacterial infection, usually passed from the primary caregiver to the child. The main bacteria responsible for dental cavities are Streptococcus mutans (S.mutans) and Lactobacillus. There is also evidence that supports that those who are in lower socioeconomic populations are at greater risk of developing ECC.
Attachment measures, or attachment assessments, are the various procedures used to assess the attachment system in children and adults. These procedures can assess patterns of attachment and individual self-protective strategies. Some assessments work across the several models of attachment and some are model-specific. Many assessments allow children and adults' attachment strategies to be classified into three primary attachment pattern groups: B-pattern, A-pattern, C-pattern. In most models, each pattern group is further broken down into several sub-patterns. Some assessments are capable of finding additional information about an individual, such as unresolved trauma, depression, history of family triangulation, and lifespan changes in the attachment pattern. Some assessments specifically or additionally look for caregiving behaviors, as caregiving and attachment are widely considered two separate systems for organizing thoughts, feelings, and behavior. Some methods assess disorders of attachment or romantic attachment.
Attachment-based therapy applies to interventions or approaches based on attachment theory, originated by John Bowlby. These range from individual therapeutic approaches to public health programs to interventions specifically designed for foster carers. Although attachment theory has become a major scientific theory of socioemotional development with one of the broadest, deepest research lines in modern psychology, attachment theory has, until recently, been less clinically applied than theories with far less empirical support. This may be partly due to lack of attention paid to clinical application by Bowlby himself and partly due to broader meanings of the word 'attachment' used amongst practitioners. It may also be partly due to the mistaken association of attachment theory with the pseudo-scientific interventions misleadingly known as attachment therapy. The approaches set out below are examples of recent clinical applications of attachment theory by mainstream attachment theorists and clinicians and are aimed at infants or children who have developed or are at risk of developing less desirable, insecure attachment styles or an attachment disorder.
The epidemiology of child psychiatric disorders is the study of the incidence, prevalence, and distribution of conditions in child and adolescent psychiatry. Subfields of pediatric psychiatric epidemiology include developmental epidemiology, which focuses on the genetic and environmental causes of child psychiatric disorders. The field of pediatric psychiatric epidemiology finds widely varying rates of childhood psychiatric disorders, depending on study population, diagnostic method, and cultural setting.
Child-to-parent violence (CPV), also recognized as abuse of parents by their children, constitutes a manifestation of domestic violence characterized by the infliction of maltreatment upon parents. This mistreatment commonly manifests in verbal or physical forms.
Birth cohort studies in Britain are four long-term medical and social studies, carried out over the lives of a group of participants, from birth. The earliest two started in 1946 and 1958.
James William Bruce Douglas was a British social researcher. Douglas was responsible for the National Survey of Health & Development that in turn led to other national birth cohort studies, such as the National Child Development Study, the 1970 British Cohort Study and the Millennium Cohort Study.
The Future of Families and Child Wellbeing Study (FFCWS) is a longitudinal birth cohort study of American families. Formerly known as the Fragile Families and Child Wellbeing Study, the study’s name was changed in January 2023.
David Murray Fergusson was a New Zealand psychologist. He was a professor of psychological medicine at the University of Otago, Christchurch, from 1999 until 2015. He is notable for work on the Christchurch Health and Development Study and for his research on abortion and mental health.
Jean Golding, FMedSci, is a British epidemiologist, and founder of the Avon Longitudinal Study of Parents and Children (ALSPAC), also known as "Children of the Nineties". She is Emeritus Professor of Paediatric and Perinatal Epidemiology at the University of Bristol.
Janis Paterson is a New Zealand academic. She is currently a full professor at the Auckland University of Technology.
Helen Aspasia Petousis-Harris is a New Zealand vaccinologist and associate professor in the Department of General Practice and Primary Health Care at the University of Auckland. She has been involved in research related to vaccination in New Zealand since 1998, with her main areas of focus being vaccine safety and effectiveness.
