DSM-III disorders in preadolescent children. Prevalence in a large sample from the general population.

Abstract: • We investigated the prevalence of DSM-III disorders in 792 children aged 11 years from the general population and found an overall prevalence of disorder of 17.6% with a sex ratio (boys-girls) of 1.7:1. The most prevalent disorders were attention deficit, oppositional, and separation anxiety disorders, and the least prevalent were depression and social phobia. Conduct disorder, overanxious disorder, and simple phobia had intermediate prevalences. Pervasive disorders, reported by more than one source, had an overall prevalence of 7.3%. Examination of background behavioral data disclosed that children identified at 11 years as having multiple disorders had a history of behavior problems since 5 years of age on parent and teacher reports. Fifty-five percent of the disorders occurred in combination with one or more other disorders, and 45% as a single disorder.

Childhood sexual abuse and mental health in adult life

Abstract: The relationship between childhood sexual abuse and mental health in adult life was investigated in a random community sample of women. There was a positive correlation between reporting abuse and greater levels of psychopathology on a range of measures. Substance abuse and suicidal behaviour were also more commonly reported by the abused group. Childhood sexual abuse was more frequent in women from disrupted homes as well as in those who had been exposed to inadequate parenting or physical abuse. While elements in the individual's childhood which increased the risks of sexual abuse were also directly associated to higher rates of adult psychopathology, abuse emerged from logistic regression as a direct contributor to adult psychopathology. Severity of abuse reported was related to the degree of adult psychopathology. The overlap between the possible effects of sexual abuse and the effects of the matrix of disadvantage from which it so often emerges were, however, so considerable as to raise doubts about how often, in practice, it operates as an independent causal element. Further, many of those reporting childhood sexual abuse did not show a measurable long-term impairment of their mental health. Abuse correlated with an increased risk for a range of mental health problems, but in most cases its effects could only be understood in relationship to the context from which it emerged.

The effect of child sexual abuse on social, interpersonal and sexual function in adult life.

Abstract: Background The association was examined between reporting child sexual abuse (CSA) and a range of social, interpersonal and sexual difficulties in adult life. Method A random sample of 2250 women were posted a questionnaire exploring a range of abuse experiences. All 248 reporting CSA were invited for interview, together with an equal number of controls. At interview a detailed inquiry was made into the CSA and into current interpersonal, social and sexual function. Results Significant associations emerged between reporting CSA and a decline in socioeconomic status, increased sexual problems, and the disruption of intimate relationships by difficulties with trust as well as a propensity to perceive their partners as uncaring and overcontrolling. CSA was more common in those from disturbed and disrupted families and in those who also reported physical and emotional abuse. This explained part, but not all, of the apparent association between CSA and negative outcomes. Conclusions Those reporting CSA are more likely to suffer social, interpersonal and sexual difficulties in adult life.

DSM-III disorders from age 11 to age 15 years.

Abstract: Although research into the continuity of disorder from childhood to adolescence is sparse, results from both longitudinal and cross sectional studies suggest that the prevalence of disorder increases for girls but may remain more stable for boys. In this paper, the methodologies of two assessment phases of the Dunedin longitudinal study have been equated to estimate the continuity of DSM-III disorder from ages 11 to 15. Although the overall prevalence of disorder doubled between the ages, this was primarily because of an increase in nonaggressive conduct disorder and major depressive episode. The sex ratios in disorder had largely reversed from a male predominance at 11 to a female predominance at 15. In terms of persistence, over 40% of those with disorder at age 11 were also identified at age 15. However, over 80% of those identified with disorder at 15 did not have a history of disorder at 11. Significant sex differences were also found in the continuity of internalizing and externalizing disorders, with externalizing disorders showing more continuity for boys, and internalizing for girls. Logistic regression models were employed to evaluate the roles family background, academic and social competence, and early histories of behavior problems may play in the determination of disorder continuity.

Prevalence of Childhood Sexual Abuse Experiences in a Community Sample of Women

Abstract: Objective The study was designed to ascertain the prevalence and nature of sexual abuse in childhood for a community sample of women. Method A two-stage design, using questionnaires and face-to-face interviews, was employed, providing information on prevalence rates, types of abuse, ages of victims, relationship to the abuser, and cohort effects. Results Nearly one woman in three reported having one or more unwanted sexual experiences before age 16 years. A significant number of these experiences (70%) involved genital contact or more severe abuse, and 12% of those abused were subjected to sexual intercourse. The abusers were usually known to the victim, being family members in 38.3% of cases and acquaintances in another 46.3% Stranger abuse accounted for 15% of all abuse experiences. Most of the abusers were young men, disclosure of the abuse was infrequent, and only 7% of all abuse was ever officially reported. Prevalence rates showed no urban/rural differences, no cohort effect with subject age, and no age differences in disclosure rates. Conclusions Child sexual abuse is common, serious, infrequently reported, and the abuser is usually known to the child. Preadolescent girls are at greatest risk.

Behavioral inhibition, sustained attention, and executive functions: Constructing a unifying theory of ADHD.

Abstract: Attention deficit hyperactivity disorder (ADHD) comprises a deficit in behavioral inhibition. A theoretical model is constructed that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution: (a) working memory, (b) self-regulation of affect-motivation-arousal, (c) internalization of speech, and (d) reconstitution (behavioral analysis and synthesis). Extended to ADHD, the model predicts that ADHD should be associated with secondary impairments in these 4 executive abilities and the motor control they afford. The author reviews evidence for each of these domains of functioning and finds it to be strongest for deficits in behavioral inhibition, working memory, regulation of motivation, and motor control in those with ADHD. Although the model is promising as a potential theory of self-control and ADHD, far more research is required to evaluate its merits and the many predictions it makes about ADHD.

Lifetime Prevalence of Mental Disorders in U.S. Adolescents: Results from the National Comorbidity Survey Replication-Adolescent Supplement (NCS-A)

Abstract: Objective To present estimates of the lifetime prevalence of DSM-IV mental disorders with and without severe impairment, their comorbidity across broad classes of disorder, and their sociodemographic correlates. Method The National Comorbidity Survey–Adolescent Supplement NCS-A is a nationally representative face-to-face survey of 10,123 adolescents aged 13 to 18 years in the continental United States. DSM-IV mental disorders were assessed using a modified version of the fully structured World Health Organization Composite International Diagnostic Interview. Results Anxiety disorders were the most common condition (31.9%), followed by behavior disorders (19.1%), mood disorders (14.3%), and substance use disorders (11.4%), with approximately 40% of participants with one class of disorder also meeting criteria for another class of lifetime disorder. The overall prevalence of disorders with severe impairment and/or distress was 22.2% (11.2% with mood disorders, 8.3% with anxiety disorders, and 9.6% behavior disorders). The median age of onset for disorder classes was earliest for anxiety (6 years), followed by 11 years for behavior, 13 years for mood, and 15 years for substance use disorders. Conclusions These findings provide the first prevalence data on a broad range of mental disorders in a nationally representative sample of U.S. adolescents. Approximately one in every four to five youth in the U.S. meets criteria for a mental disorder with severe impairment across their lifetime. The likelihood that common mental disorders in adults first emerge in childhood and adolescence highlights the need for a transition from the common focus on treatment of U.S. youth to that of prevention and early intervention.

Prevalence and Development of Psychiatric Disorders in Childhood and Adolescence

Abstract: Results: Although 3-month prevalence of any disorder averaged 13.3% (95% confidence interval [CI], 11.7%15.0%), during the study period 36.7% of participants (31% of girls and 42% of boys) had at least 1 psychiatric disorder. Some disorders (social anxiety, panic, depression, and substance abuse) increased in prevalence, whereas others, including separation anxiety disorder and attention-deficit/hyperactivity disorder (ADHD), decreased. Lagged analyses showed that children with a history of psychiatric disorder were 3 times more likely than those with no previous disorder to have a diagnosis at any subsequent wave (odds ratio, 3.7; 95% CI, 2.94.9; P.001). Risk from a previous diagnosis was high among both girls and boys, but it was significantly higher among girls. Continuity of the same disorder (homotypic) was significant for all disorders except specific phobias. Continuity from one diagnosis to another (heterotypic) was significant from depression to anxiety and anxiety to depression, from ADHD to oppositional defiant disorder, and from anxiety and conduct disorder to substance abuse. Almost all the heterotypic continuity was seen in girls. Conclusions: The risk of having at least 1 psychiatric disorder by age 16 years is much higher than point estimates would suggest. Concurrent comorbidity and homotypic and heterotypic continuity are more marked in girls than in boys.

A gradient of childhood self-control predicts health, wealth, and public safety

Abstract: Policy-makers are considering large-scale programs aimed at self-control to improve citizens’ health and wealth and reduce crime. Experimental and economic studies suggest such programs could reap benefits. Yet, is self-control important for the health, wealth, and public safety of the population? Following a cohort of 1,000 children from birth to the age of 32 y, we show that childhood self-control predicts physical health, substance dependence, personal finances, and criminal offending outcomes, following a gradient of self-control. Effects of children's self-control could be disentangled from their intelligence and social class as well as from mistakes they made as adolescents. In another cohort of 500 sibling-pairs, the sibling with lower self-control had poorer outcomes, despite shared family background. Interventions addressing self-control might reduce a panoply of societal costs, save taxpayers money, and promote prosperity.
