Background: Studies on early intervention have reported significant gains for many children with autism. Knowledge on how these children fare in adulthood is limited.
Objective: To examine long-term outcome of children with autism who received different forms of early intervention.
Method: Participants were 15 young people who had all been diagnosed with ICD-10 childhood autism during the preschool years. Five received intervention based on the UCLA model for early intensive behavioral intervention, and 10 received eclectic treatment. Participants were followed from their first autism diagnosis during the preschool years (time 1) to the age of six years (time 2). The participants are now in their twenties (time 3), and at this point in time, information on autism symptoms, co-occurring disorders, quality of life, functioning, participation, adaptive behavior, and overall outcome was gathered from parents. Six of the participants answered questionnaires on quality of life, functioning, and participation.
Results: The groups were comparable on all measures at time 1. Reassessment at time 2 showed that the early intensive behavioral intervention group had made significant gains in IQ, and that autism symptoms had decreased significantly, whereas such changes were not found for the eclectic treatment group. At time 3, most participants had considerable autism symptoms. Approximately half of them had received diagnosis of a co-occurring condition. Their quality of life and adaptive behavior was less favorable than that of the general population, but only a third had “poor” overall outcome. However, at time 3, hardly any differences were found between the groups.
Conclusions: To maintain gains made during the preschool years, appropriate intervention and services may need to be extended into adulthood. These services should take into account the perceived needs of the individual, as expressed by himself/herself and his/her family.

Fatigue is widespread in the population, particularly among working people. Exhaustion disorder (ED), a clinical manifestation of burnout, is common, but, after treatment, about one-third still experience fatigue and other physical symptoms. We propose that in some instances, fatigue as a persistent physical symptom (PPS) might be a more appropriate formulation of ED patients’ fatigue problems, and we suggest that ED patients who meet fatigue PPS criteria will differ from other ED patients in terms of psychological distress, non-fatigue PPSs and functional impairment. Questionnaires were sent to 10,956 members of a trade union of which 2479 (22.6%) responded. Of 1090 participants who met criteria for ED, 106 (9.7%) met criteria for fatigue as a PPS. Participants who met fatigue PPS criteria scored on average higher on measures of depression, anxiety and functional impairment and were more likely to have clinically significant scores. Moreover, they had 27 times higher odds of meeting other PPS subtypes and reported more non-fatigue PPS subtypes, suggesting a more complex health problem. Specific evidence-based interventions are available for both ED and PPSs, and therefore, it is crucial to accurately formulate the fatigue problem reported by patients to provide appropriate treatment.

Background: In recent years, cognitive behavioural group therapies (CBGT) have been increasingly deployed as a strategy to increase the efficiency and cost-effectiveness in treatment of common mental health problems. The vast majority of these therapies are disorder specific, but in the last few years there has been growing interest in transdiagnostic CBGT. Aims: The aim of this study was twofold: to evaluate the treatment effects of transdiagnostic CBGT on disorder specific symptoms and what (if any) differences would be observed in the treatment effects with regard to general as opposed to disorder specific symptoms measured pre- and post-treatment. Method: The participants were 233 adult patients diagnosed with depression and/or anxiety disorders. They underwent a 6-week transdiagnostic CBGT. To compare treatment effects on general and disorder specific symptoms, raw scores on all measures were converted to standardized scores. Results: Pre–post differences were significant and there was no evidence that treatment was differentially effective for general and disorder specific symptoms. Effect sizes ranged from medium to large. Conclusion: The 6-week transdiagnostic CBGT is feasible for a wide range of mood and anxiety disorders. The results indicate that low-intensity transdiagnostic group therapies may have similar effects on both general and disorder specific symptoms.

Cognitive behavioural therapy (CBT) has, in the space of 50 years, evolved into the dominant modality in psychological therapy. Mechanism/s of change remain unclear, however.
In this paper, we will describe key features of CBT that account for the pace of past and future developments, with a view to identifying candidates for mechanism of change. We also highlight the distinction between 'common elements' and 'mechanisms of change' in psychological treatment.
The history of how behaviour therapy and cognitive therapy developed are considered, culminating in the wide range of strategies which now fall under the heading of cognitive behavioural therapy (CBT). We consider how the empirical grounding of CBT has led to the massive proliferation of effective treatment strategies. We then consider the relationship between 'common factors' and 'mechanisms of change', and propose that a particular type of psychological flexibility is the mechanism of change not only in CBT but also effective psychological therapies in general.
Good psychological therapies should ultimately involve supporting people experiencing psychological difficulties to understand where and how they have become 'stuck' in terms of factors involved in maintaining distress and impairment. A shared understanding is then evaluated and tested with the intention of empowering and enabling them to respond more flexibly and thereby reclaim their life.

A randomized controlled trial reporting functional outcomes of cognitive–behavioural therapy in medication-treated adults with ADHD and comorbid psychopathology
2017
Studies assessing psychological treatment of attention deficit hyperactivity disorder (ADHD) in adults are increasingly reported. However, functional outcomes are often neglected in favour of symptom outcomes. We investigated functional outcomes in 95 adults with ADHD who were already treated with medication and randomized to receive treatment as usual (TAU/MED) or psychological treatment (CBT/MED) using a cognitive–behavioural programme, R&R2ADHD, which employs both group and individual modalities. RATE-S functional outcomes associated with ADHD symptoms, social functioning, emotional control and antisocial behaviour were given at baseline, end of treatment and three-month follow-up. The Total composite score of these scales is associated with life satisfaction. In addition, independent evaluator ratings of clinicians who were blind to treatment arm were obtained on the Clinical Global Impression scale at each time point. CBT/MED showed overall (combined outcome at end of treatment and 3-month follow-up) significantly greater functional improvement on all scales. Post-group treatment effects were maintained at follow-up with the exception of emotional control and the Total composite scales, which continued to improve. The largest treatment effect was for the RATE-S Total composite scale, associated with life satisfaction. CGI significantly correlated with all outcomes except for social functioning scale at follow-up. The study provides further evidence for the effectiveness of R&R2ADHD and demonstrates the importance of measuring functional outcomes. The key mechanism associated with improved functional outcomes is likely to be behavioural control.

Purpose
The principal aims of this study are to identify risk factors associated with police arrest and false confessions and to investigate whether the severity of the ADHD condition/symptoms increases the risk.
Methods
22,226 young persons in Iceland anonymously completed self-report questionnaires screening for conduct disorder and ADHD. In addition, they stated whether they had a diagnosis of ADHD and had received ADHD medication, and their history of offending, police interrogation and false confession. Participants were stratified into two age groups, 14–16 and 17–24 years.
Results
The older group was significantly more likely to have been interrogated by the police but the younger group were much more vulnerable to false confession during interrogation. Males were more likely to be at risk for both than females. The severity of the ADHD condition increased the risk of both interrogation and false confession. Negative binomial regressions showed that age, gender, conduct disorder, offending, and ADHD symptoms were all significant predictors of both interrogations and number of false confessions. Conduct disorder was the single best predictor of police interrogation, but the findings were more mixed regarding false confessions. Young people presenting with a combination of severe ADHD and comorbid conduct disorder had the worst outcome for both interrogation and false confessions.
Conclusions
The findings endorse the need for support of persons with ADHD to be put in place to ensure fair due process and to prevent miscarriages of justice.

Attention Deficit Disorder with Hyperactivity - epidemiology
2017
Purpose
To examine the role of family conflict in the relationship between attention deficit hyperactivity disorder (ADHD) and conduct disorder (CD).
Methods
A cross-sectional national population survey was carried out among 10,838 14–16 year old students in all secondary schools in Iceland. Three latent measures, financial status, ADHD and CD, and one observed measure, family structure, were included in the study. A structural equation model was used to evaluate direct effects between ADHD and CD for four different groups; females and males, experiencing family conflict and those not experiencing family conflict.
Results
ADHD was significantly and positively associated with CD for all groups. When controlling for financial status and family structure it was found that ADHD was positively and significantly associated with CD for adolescent females and males not experiencing family conflict as well as for those experiencing family conflict. The link between ADHD and CD was significantly stronger for those adolescents who had experienced family conflict compared to those who had not experienced family conflict. These results suggest that family conflict moderates the association between ADHD and CD for both girls and boys.
Conclusions
The results of this study indicate that family environment and ADHD symptoms are important when predicting CD among adolescent youth. Most notably, family conflict exacerbates the effects of ADHD symptoms on CD among both females and males.

Anger
2008
Drawing on Agnew’s general strain theory, we examined whether depressed mood and anger mediated the effects of sexual abuse on suicidal behavior and delinquency. Participants included 9,113 students attending high schools in Iceland. Structural equation modeling showed that, while controlling for family structure and parental education, being exposed to strain in the form of sexual abuse was positively related to both depressed mood and anger. The effects of sexual abuse on suicidal behavior of both boys and girls were twice as strong through depressed mood as through anger. The effects of sexual abuse on outwardly-directed forms of delinquency for both genders were stronger through anger than through depressed mood. These findings highlight the complex nature of the effects of strain on adolescents’ emotions and behavior. Moreover, they show that depression—in contrast to outwardly-directed delinquency, where feelings of anger are predominantly influential—is more relevant than anger to suicidal behavior.

Motivation for offending and personality
2004
Purpose. The main aim of the study was to examine the relationship between motivation for offending and personality. Method. A specially constructed Offending Motivation Questionnaire (OMQ) was developed along the lines of Farrington's (1986, 1993) theoretical framework. The OMQ, the Mak Self‐Reported Delinquency Scale, the Gudjonsson Compliance Scale (GCS), the Gough Socialisation Scale, the Rosenberg Self‐Esteem Scale, and the Gudjonsson Blame Attribution Inventory (BAI‐R) were administered to two groups of students: college students and university students. Results. Factor analysis of the OMQ revealed four motivational factors for offending (Compliance, Provocation, Financial, Excitement) and one further factor associated with the failure to appreciate the consequences of the criminal act. As predicted, the GCS correlated significantly with a compliance motive (i.e. being coerced, manipulated, or tricked into crime by a peer, or eagerness to please a peer), whereas the remaining four factors were associated with a low score on the Gough Socialisation Scale. External and Mental Element attributions were mainly found to be associated with provocation and consequences factors. Conclusions. The findings support the view that there is a relationship between the motivation for offending, failure to appreciate the consequences of one's actions and personality. Further research should focus on studying this relationship among criminal populations.

2004
Purpose. The main aim of the study was to examine the reasons and personality factors associated with confessions and denials. It was hypothesized that antisocial personality traits and active involvement in criminal behaviour would distinguish true confessors and true deniers from false confessors and false deniers. Method. The participants were 1,080 students in further education in Iceland. Each was asked about false admissions made to teachers and parents in the past, as well as about confessions or denials (true and false) made to the police during questioning, and the reasons for having responded in the way they did. The participants also completed questionnaires relating to offending, personality and self‐esteem. Results. One‐quarter (25%) of the participants stated that they had in the past been interrogated by the police in relation to a suspected offence, of whom 59% said they had confessed. A small minority of those interrogated (3.7%; 1% of the total sample) claimed to have made false confessions to the police, whereas 10% claimed to have made false confessions to teachers or parents. Males were significantly more likely to report false confessions than females. False confessions and false denials were significantly associated with antisocial personality traits, with Eysenck Personality Questionnaire Psychoticism being the single best predictor. Those participants who made true confessions and true denials were most normal in their personality. Conclusions. Personality is a significant predictor of who makes false confessions and false denials.
