This 3-year follow-up study compares background variables, extent of criminality and criminal recidivism in the form of all court convictions, the use of inpatient care, and number of early deaths in Swedish institutionalized adolescents (N=100) with comorbid substance use disorders (SUD) and Attention-Deficit/Hyperactivity Disorder (ADHD) (n=25) versus those with SUD but no ADHD (n=30), and those without SUD (n=45). In addition it aims to identify whether potential risk factors related to these groups are associated with persistence in violent criminality. Results showed almost no significant differences between the three diagnostic groups, but the SUD plus ADHD group displayed a somewhat more negative outcome with regard to criminality, and the non-SUD group stood out with very few drug related treatment episodes. However, the rate of criminal recidivism was strikingly high in all three groups, and the use of inpatient care as well as the number of untimely deaths recorded in the study population was dramatically increased compared to a age matched general population group. Finally, age at first conviction emerged as the only significant predictor of persistence in violent criminality with an AUC of .69 (CI (95%) .54-.84, p=.02). Regardless of whether SUD, with or without ADHD, is at hand or not, institutionalized adolescents describe a negative course with extensive criminality and frequent episodes of inpatient treatment, and thus requires a more effective treatment than present youth institutions seem to offer today. However, the few differences found between the three groups, do give some support that those with comorbid SUD and ADHD have the worst prognosis with regard to criminality, health, and untimely death, and as such are in need of even more extensive treatment interventions.
This project studies the effect of group-based Acceptance and Commitment Therapy (ACT) following Attention Bias Modification (ABM) on residual symptoms in recurrent depression. ACT is a cognitive-behavioral intervention combining acceptance and mindfulness processes with commitment and behavior-change processes. ACT enjoys modest empirical support in treating depression and has also shown promising results in secondary prevention of depression. The experimental cognitive bias modification (ABM) procedure has been shown to reduce surrogate markers of depression vulnerability in patients in remission from depression. The aim of the current project is to investigate if the effect of group-based ACT on reducing residual depressive symptoms can be enhanced by preceding it with ABM. Also, assessment of the relationship between conceptually relevant therapeutic processes and outcome will be investigated.
An invitation to participate in this project was extended to 120 individuals within a larger sample who had just completed a separate randomized, multisite, clinical trial (referred to hereafter as Phase 1) in which they received either ABM (n = 60) or a control condition without bias modification (n = 60). This larger Phase-1 sample consisted of 220 persons with a history of at least two episodes of major depression who were currently in remission or not fulfilling the criteria of major depression. After its inclusion, Phase-1 participants from the Sørlandet site (n = 120) were also recruited for this study in which they received an 8-week group-based ACT intervention. Measures will be taken immediately after Phase 1, 1 month, 2 months, 6 months, and 1 year after the conclusion of Phase 1.
This study sequentially combines acceptable, nondrug interventions from neuropsychology and cognitive-behavioral psychology in treating residual symptoms in depression. The results will provide information about the effectiveness of treatment and on mechanisms and processes of change that may be valuable in understanding and further developing ABM and ACT, combined and alone.

Acetaminophen (paracetamol) is the most commonly used medication for pain and fever during pregnancy in many countries. Research data suggest that acetaminophen is a hormone disruptor, and abnormal hormonal exposures in pregnancy may influence fetal brain development.
To evaluate whether prenatal exposure to acetaminophen increases the risk for developing attention-deficit/hyperactivity disorder (ADHD)-like behavioral problems or hyperkinetic disorders (HKDs) in children.
We studied 64,322 live-born children and mothers enrolled in the Danish National Birth Cohort during 1996-2002.
Acetaminophen use during pregnancy was assessed prospectively via 3 computer-assisted telephone interviews during pregnancy and 6 months after child birth.
To ascertain outcome information we used (1) parental reports of behavioral problems in children 7 years of age using the Strengths and Difficulties Questionnaire; (2) retrieved HKD diagnoses from the Danish National Hospital Registry or the Danish Psychiatric Central Registry prior to 2011; and (3) identified ADHD prescriptions (mainly Ritalin) for children from the Danish Prescription Registry. We estimated hazard ratios for receiving an HKD diagnosis or using ADHD medications and risk ratios for behavioral problems in children after prenatal exposure to acetaminophen.
More than half of all mothers reported acetaminophen use while pregnant. Children whose mothers used acetaminophen during pregnancy were at higher risk for receiving a hospital diagnosis of HKD (hazard ratio?=?1.37; 95% CI, 1.19-1.59), use of ADHD medications (hazard ratio?=?1.29; 95% CI, 1.15-1.44), or having ADHD-like behaviors at age 7 years (risk ratio?=?1.13; 95% CI, 1.01-1.27). Stronger associations were observed with use in more than 1 trimester during pregnancy, and exposure response trends were found with increasing frequency of acetaminophen use during gestation for all outcomes (ie, HKD diagnosis, ADHD medication use, and ADHD-like behaviors; P trend
STUDY DESIGN: A single-blinded, randomized treatment study with a follow-up period of 6 months. OBJECTIVE: To study the long-term consequences of whiplash neck sprain injuries in patients treated with two different regimes during the first 14 days after the car accident. Patients in the first group were encouraged to act as usual, i.e., continue to engage in their normal, pre-injury activities; that group was compared with another group of patients who were given time off from work and who were immobilized using a soft neck collar. The end point of the comparison was the evaluation of subjective symptoms 6 months after the accident. SUMMARY OF BACKGROUND DATA: Few randomized treatment studies have been performed to evaluate the clinical outcome for patients with neck sprain. METHOD: Patients who participated in the study were recruited from the Emergency Clinic at the University Hospital in Trondheim, Norway. The study group included 201 patients (47% of the study group) with neck sprain that resulted from a car accident. Neck and shoulder movements and subjective symptoms, which were assessed using several different measurements, were assessed during the follow-up period. RESULTS: There was a significant reduction of symptoms from the time of intake to 24 weeks after the treatment period in both groups. There was a significantly better outcome for the act-as-usual group in terms of subjective symptoms, including pain localization, pain during daily activities, neck stiffness, memory, and concentration, and in terms of visual analog scale measurements of neck pain and headache. CONCLUSIONS: The outcome was better for patients who were encouraged to continue engaging in their normal, pre-injury activities as usual than for patients who took sick leave from work and who were immobilized during the first 14 days after the neck sprain injury.
Adapting an attention-deficit hyperactivity disorder parent training intervention to different cultural contexts: The experience of implementing the New Forest Parenting Programme in China, Denmark, Hong Kong, Japan, and the United Kingdom.
The New Forest Parenting Programme (NFPP) is a parenting program developed for parents who have a child with attention-deficit hyperactivity disorder (ADHD). It is a manualized program that is delivered in a parent's home over 8 weeks, or in a group format, or through a self-help manual. Three randomized controlled trials have been carried out in the United Kingdom. The NFPP group has adapted the program according to feedback from parents and therapists, and for use with different populations, both within the United Kingdom and internationally. The first international trial took place in New York, United States. Trials in Denmark, Hong Kong, and Japan followed. More recently, a trial of the self-help manual has been carried out in mainland China. This paper will outline the adaptions that were needed in order to be able to deliver the program in different countries with their own expectations of parenting, culture, and language. Training had to be differently focused; manuals and handouts had to be revised, translated and back-translated; and supervision had to be delivered at a distance to maintain the fidelity of the program. The international group will outline their experience of running trials in their own countries with the NFPP in a face-to-face format (Denmark), a group format (Hong Kong and Japan), and a self-help format (mainland China).
The objective of this paper was to determine the degree of diagnostic overlap between attention deficit disorder with hyperactivity (ADDH) and conduct disorder (CD) and to see whether ADDH children show a different pattern of demographic, familial, and developmental correlates compared to CD children. The sample for this study consisted of 2,697 4- to 16-year-olds who participated in the Ontario Child Health Study. In terms of diagnostic overlap, ADDH and CD occurred together more often than by chance alone, particularly among girls. Pure groups of ADDH and CD children differed in a variety of ways. In general, ADDH children were younger and had experienced more developmental delays and less psychosocial disadvantage than the CD children. No differences were found with respect to associated impairments, a measure of severity. Children with both ADDH and CD (a mixed group) appeared to represent a true hybrid disorder rather than one diagnosis or the other. These findings support the validity of ADDH compared to CD, at least in terms of the pattern of correlates.
INTRODUCTION: Smoking during pregnancy has been reported to be associated with a twofold to fourfold increased risk of attention-deficit hyperactivity disorder (ADHD) in the offspring. Genetic and socioeconomic confounders may contribute to this association. The aim of this study was to investigate the association between fetal exposure to maternal smoking during pregnancy and ADHD, taking such potential confounders into consideration. METHODS: A register study in a population of 982,856 children, 6-19 years of age, born at term, and residents in Sweden in 2006 was conducted. Logistic regression was used to calculate odds ratios (ORs) of maternal smoking habits during pregnancy on ADHD medication in the 927,007 study subjects where maternal smoking habits were available from the Medical Birth Register in the presence of socioeconomic and parental psychiatric morbidity confounders. To adjust the analysis also for genetic confounding, we used a within-mother between-pregnancy approach in offspring of 26,292 mothers with inconsistent smoking habits (smoking/non-smoking) between pregnancies. RESULTS: The OR for ADHD medication in offspring of mothers who smoked >or=10 cigarettes/day was 2.86 (2.66-3.07) in the entire study population after adjustment for sex and age, while this same exposure yielded an OR of only 1.26 (0.95-1.58) when two pregnancies of the same mother were analyzed in a within-subjects design. DISCUSSION: Smoking during pregnancy has a strong association with ADHD in the offspring in the general Swedish population, but this risk is primarily explained by genetic and socioeconomic confounding.

BACKGROUND: Pharmacological and genetic studies suggest the importance of the dopaminergic, serotonergic, and noradrenergic systems in the pathogenesis of Attention Deficit Hyperactivity Disorder (ADHD) and Disruptive Behavior Disorder (DBD). We have, in a population-based sample, studied associations between dimensions of the ADHD/DBD phenotype and Monoamine Oxidase B (MAO-B) activity in platelets and polymorphisms in two serotonergic genes: the Monoamine Oxidase A Variable Number of Tandem Repeats (MAO-A VNTR) and the 5-Hydroxytryptamine Transporter gene-Linked Polymorphic Region (5-HTT LPR). METHODS: A population-based sample of twins, with an average age of 16 years, was assessed for ADHD/DBD with a clinical interview; Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). Blood was drawn from 247 subjects and analyzed for platelet MAO-B activity and polymorphisms in the MAO-A and 5-HTT genes. RESULTS: We found an association in girls between low platelet MAO-B activity and symptoms of Oppositional Defiant Disorder (ODD). In girls, there was also an association between the heterozygote long/short 5-HTT LPR genotype and symptoms of conduct disorder. Furthermore the heterozygote 5-HTT LPR genotype in boys was found to be associated with symptoms of Conduct Disorder (CD). In boys, hemizygosity for the short MAO-A VNTR allele was associated with disruptive behavior. CONCLUSION: Our study suggests that the serotonin system, in addition to the dopamine system, should be further investigated when studying genetic influences on the development of Disruptive Behavior Disorders.
BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) occurs more frequently than expected in prevalent cohorts with epilepsy. The association has been attributed to the epilepsy or its treatment, although it is impossible to determine in previous studies which condition occurs first. OBJECTIVES: To conduct a population-based case-control study of all newly diagnosed unprovoked seizures among Icelandic children younger than 16 years to address the question of time order. DESIGN: Children with seizures were matched to the next 2 same-sex births from the population registry. The Diagnostic Interview Schedule for Children was used to make a DSM-IV diagnosis of ADHD in a standardized fashion among cases and controls aged 3 to 16 years. RESULTS: A history of ADHD was 2.5-fold more common among children with newly diagnosed seizures than among control subjects (95% confidence interval [CI], 1.1-5.5). The association was restricted to ADHD predominantly inattentive type (odds ratio [OR], 3.7; 95% CI, 1.1-12.8), not ADHD predominantly hyperactive-impulsive type (OR, 1.8; 95% CI, 0.6-5.7) or ADHD combined type (OR, 2.5; 95% CI, 0.3-18.3). Seizure type, etiology, sex, or seizure frequency at diagnosis (1 or >1) did not affect findings. CONCLUSION: Attention-deficit/hyperactivity disorder occurs more often than expected before unprovoked seizures, suggesting a common antecedent for both conditions.
