The FTF (Five to Fifteen): the development of a parent questionnaire for the assessment of ADHD and comorbid conditions

Continuity From Prelinguistic Communication to Later Language Ability: A Follow-Up Study From Infancy to Early School Age

PURPOSE

This longitudinal study examined the development of prelinguistic skills and the continuity of communication and language from the prelinguistic stage to school age.

METHOD

Prelinguistic communication of 427 Finnish children was followed repeatedly from 6 to 18 months of age (n = 203-322 at ages 6, 9, 12, 15, and 18 months), and its associations with language ability at ages 2;0 (n = 104), 3;0 (n = 112), 4;7 (n = 253), 5;3 (n = 102), and 7;9 (n = 236) were examined using latent growth curve modeling.

RESULTS

Prelinguistic development across several skills emerged as a rather stable intraindividual characteristic during the first 2 years of life. Continuity from prelinguistic development to later language ability was indicated. The common level and growth of prelinguistic skills were significant predictors of language ability between ages 2;0 (years;months) and 7;9; the percentage explained varied between 10.5% and 53.3%. A slow pace of development across multiple skills, in particular, led to weaker language skills.

CONCLUSIONS

The results support (a) the idea of a developmental continuum from prelinguistic to linguistic ability and (b) the dimensional view of language ability by indicating that individual variations in early communication skills show consistency that extends beyond the toddler years. Our results also advocate developmental surveillance of early communication by emphasizing the significance of growth in predicting language development.

Questionnaire of Memory (Q-MEM): A new measure of everyday memory functioning in school-age children

We present a new measure of everyday memory, the Questionnaire of Memory (Q-MEM), which is specifically adapted for the ecological assessment of memory disorders in school-age children and constructed with four sections tapping effortful/intentional learning, automatic/procedural learning, prospective memory/organization, and working memory. Confirmatory Factor Analyses supported the Q-MEM's four-factor structure in 700 five-to twelve-year-old children. The analyses also revealed a good internal reliability and a good test-retest fidelity. Finally, comparisons between Q-MEM profiles of children with learning disabilities and typically developing children revealed significant differences. Therefore, the Q-MEM is a promising measure for identifying memory problems in children.

Polyunsaturated fatty acids (PUFAs) for children with specific learning disorders

BACKGROUND

About 5% of school children have a specific learning disorder, defined as unexpected failure to acquire adequate abilities in reading, writing or mathematics that is not a result of reduced intellectual ability, inadequate teaching or social deprivation. Of these events, 80% are reading disorders. Polyunsaturated fatty acids (PUFAs), in particular, omega-3 and omega-6 fatty acids, which normally are abundant in the brain and in the retina, are important for learning. Some children with specific learning disorders have been found to be deficient in these PUFAs, and it is argued that supplementation of PUFAs may help these children improve their learning abilities.

OBJECTIVES

1. To assess effects on learning outcomes of supplementation of polyunsaturated fatty acids (PUFAs) for children with specific learning disorders.2. To determine whether adverse effects of supplementation of PUFAs are reported in these children.

SEARCH METHODS

In November 2015, we searched CENTRAL, Ovid MEDLINE, Embase, PsycINFO, 10 other databases and two trials registers. We also searched the reference lists of relevant articles.

SELECTION CRITERIA

Randomised controlled trials (RCTs) or quasi-RCTs comparing PUFAs with placebo or no treatment in children younger than 18 years with specific learning disabilities, as diagnosed in accordance with the fifth (or earlier) edition of theDiagnostic and Statistical Manual of Mental Disorders (DSM-5), or the 10th (or earlier) revision of the International Classification of Diseases (ICD-10) or equivalent criteria. We included children with coexisting developmental disorders such as attention deficit hyperactivity disorder (ADHD) or autism.

DATA COLLECTION AND ANALYSIS

Two review authors (MLT and KHT) independently screened the titles and abstracts of articles identified by the search and eliminated all studies that did not meet the inclusion criteria. We contacted study authors to ask for missing information and clarification, when needed. We used the GRADE approach to assess the quality of evidence.

MAIN RESULTS

Two small studies involving 116 children, mainly boys between 10 and 18 years of age, met the inclusion criteria. One study was conducted in a school setting, the other at a specialised clinic. Both studies used three months of a combination of omega-3 and omega-6 supplements as the intervention compared with placebo. Although both studies had generally low risk of bias, we judged the risk of reporting bias as unclear in one study, and as high in the other study. In addition, one of the studies was funded by industry and reported active company involvement in the study.None of the studies reported data on the primary outcomes of reading, writing, spelling and mathematics scores, as assessed by standardised tests.Evidence of low quality indicates that supplementation of PUFAs did not increase the risk of gastrointestinal disturbances (risk ratio 1.43, 95% confidence interval 0.25 to 8.15; two studies, 116 children). Investigators reported no other adverse effects.Both studies reported attention deficit hyperactivity disorder (ADHD)-related behaviour outcomes. We were unable to combine the results in a meta-analysis because one study reported findings as a continuous outcome, and the other as a dichotomous outcome. No other secondary outcomes were reported.We excluded one study because it used a cointervention (carnosine), and five other studies because they did not provide a robust diagnosis of a specific learning disorder. We identified one ongoing study and found three studies awaiting classification.

AUTHORS' CONCLUSIONS

Evidence is insufficient to permit any conclusions about the effect of PUFAs on the learning abilities of children with specific learning disorders. Well-designed RCTs with clearly defined populations of children with specific learning disorders who have been diagnosed by standardised diagnostic criteria are needed.

Executive Functioning and Learning Skills of Adolescent Children Born at Fewer than 26 Weeks of Gestation

Aims

To assess the cognitive and behavioral aspects of executive functioning (EF) and learning skills in extremely preterm (EPT) children compared with term control children aged 10 to 15 years.

Methods

A total of 132 of 134 (98% of all eligible survivors) EPT children born at the 2 Swedish regional tertiary care centers from 1992 to 1998 (mean age = 12 years, mean birth weight = 718 g, and mean gestational age = 24.4 weeks) and 103 matched term controls were assessed. General intelligence was assessed using the Wechsler Intelligence Scale for Children (WISC-III-R), and cognitive aspects of EF were analyzed using EF-sensitive subscales of the WISC-III-R and Tower test of the Delis-Kaplan Executive Function Scale (D-KEFS). Behaviors related to EF and learning skills were assessed using the Five to Fifteen questionnaire, which is a validated parent and teacher instrument. Academic performance in school was assessed by teachers’ responses on Achenbach’s Teachers Report Form. Analyses performed included multivariate analyses of covariance (ANCOVA and MANCOVA) and logistic regression analyses.

Results

The EPT children displayed significant deficits in cognitive aspects of EF compared with the controls, exhibiting decreases on the order of 0.9 SD to 1.2 SD for tasks of verbal conceptual reasoning, verbal and non-verbal working memory, processing speed and planning ability (P <0.001 for all). After excluding the children with major neurosensory impairment (NSI) or a Full Scale intelligence quotient (FSIQ) of < 70, significant differences were observed on all tests. Compared with controls, parents and teachers of EPT children reported significantly more EF-related behavioral problems. MANCOVA of teacher-reported learning skills in children with FSIQ >70 and without major NSI revealed no interactions, but significant main effects were observed for the behavioral composite executive function score, group status (EPT vs control) and FSIQ, for which all effect sizes were medium to large. The corresponding findings of MANCOVA of the parent-reported learning skills were very similar. According to the teachers’ ratings, the EPT children were less well adjusted to the school environment.

Conclusion

EPT children born in the 1990s who received active perinatal care are at an increased risk of executive dysfunction, even after excluding children with significant neurodevelopmental disabilities. Even mild to moderate executive dysfunctions has a significant impact on learning skills. These findings suggest the need for timely interventions that address specific cognitive vulnerabilities and executive dysfunctions.

Biomarkers of nutrition and stress in pregnant women with a history of eating disorders in relation to head circumference and neurocognitive function of the offspring

Background

Eating disorders during pregnancy can affect fetal growth and the child’s early development, but the underlying mechanisms have not been elucidated. The aim of the present study was to investigate serum biomarkers of nutrition and stress in pregnant women with previous eating disorders compared to controls and in relation to head circumference and early neurocognitive development of the offspring.

Methods

In a longitudinal cohort study, pregnant nulliparous non-smoking women with a history of anorexia nervosa (n = 20), bulimia nervosa (n = 17) and controls (n = 59) were followed during pregnancy and their children’s growth and neurocognitive development were followed up to five years of age. We investigated maternal serum biomarkers of nutrition and stress (ferritin, cortisol, thyroid-stimulating hormone, free thyroxine, insulin, insulin-like growth factor I (IGF-I) and IGF binding protein 1) in blood samples collected during early pregnancy and compared between groups (ANOVA, LSD post-hoc test). The results were related to previous data on head circumference at birth and neurocognitive development at five years of age of the offspring (Spearman rank correlation or Pearson correlation test).

Results

Serum levels of ferritin in the women with previous anorexia nervosa, but not in those with a history of bulimia nervosa, were significantly lower than in the controls (p < 0.01), and correlated strongly to impaired memory function in their children (rs = −0.70, p < 0.001). Maternal serum levels of free thyroxine were similar between groups but correlated positively to reduced head circumference at birth of the children in the bulimia nervosa group (r = 0.48, p < 0.05), and with the same tendency in the anorexia nervosa group (r = 0.42, p = 0.07), but not in the controls (r = 0.006). There were no significant differences in cortisol or the other biomarkers between groups.

Conclusions

Low maternal serum ferritin in women with previous anorexia nervosa may be of importance for impaired memory capacity in the offspring at five years of age. Our results also indicate that thyroxin levels in pregnant women with previous eating disorders are positively associated with fetal head growth.

Spelling difficulties in school-aged girls with attention-deficit/hyperactivity disorder: behavioral, psycholinguistic, cognitive, and graphomotor correlates

Writing difficulties are common among children with attention-deficit/hyperactivity disorder (ADHD), but the nature of these difficulties has not been well studied. Here we relate behavioral, psycholinguistic, cognitive (memory/executive), and graphomotor measures to spelling skills in school-age girls with ADHD (n = 30) and an age-matched group of typically developed spellers (TYPSP, n = 35). When subdividing the ADHD group into those with poor (ADHDPSP, n = 19) and typical spelling (ADHDTYPSP, n = 11), the two subgroups did not differ with regard to inattentive or hyperactive-impulsive symptom severity according to parent or teacher ratings. Both ADHD subgroups also had equally severe difficulties in graphomotor control-handwriting and (parent ratings of) written expression as compared to the TYPSP group. In contrast, ADHDPSP had problems relative to ADHDTYPSP and TYPSP on phonological and orthographic recoding (choice tasks) and verbal memory (digit span) and were more likely to make commissions on a continuous performance task (CPT). Further analyses using the collapsed ADHD group showed that both digit span and the presence of CPT commissions predicted spelling performance independently of each other. Finally, results showed that phonological recoding skills mediated the association between digit span and spelling performance in ADHD. Theoretical and educational implications are discussed.

Associations between toddler-age communication and kindergarten-age self-regulatory skills

PURPOSE

In this study, the authors aimed at gaining understanding on the associations of different types of early language and communication profiles with later self-regulation skills by using longitudinal data from toddler age to kindergarten age.

METHOD

Children with early language profiles representing expressive delay, broad delay (i.e., expressive, social, and/or symbolic), and typical language development were compared in domains of kindergarten-age executive and regulative skills (attentional/executive functions, regulation of emotions and behavioral activity, and social skills) assessed with parental questionnaires.

RESULTS

Children with delay in toddler-age language development demonstrated poorer kindergarten-age self-regulation skills than children with typical early language development. Broad early language delays were associated with compromised social skills and attentional/executive functions, and early expressive delays were associated with a generally lower level of kindergarten-age executive and regulative skills. Regression analyses showed that both earlier and concurrent language had an effect especially on the attentional/executive functions.

CONCLUSIONS

The findings suggest that different aspects of toddler-age language have differential associations with later self-regulation. Possible mechanisms linking early language development to later self-regulative development are discussed.

Excellent Word-Reading Ability in the Context of an Autism Spectrum Disorder: A Case Study of a Swedish-Speaking 7-Year-Old Boy

This case study seeks to extend our knowledge of the phenotype associated with excellent word reading in autism spectrum disorder by a detailed examination of psycholinguistic, neuropsychological/cognitive, and classroom/academic functioning of a Swedish-speaking 7-year-old boy (called “Jonas”). On age-referenced word reading-decoding assessment, Jonas scored among the top 7%. Reading comprehension status varied as a function of information source. Jonas’s phonological processing and phonological memory performance was found to be normal to strong. In contrast, he scored poorly on tests of oral semantic, syntactical, and narrative language. On the WISC-III, Jonas performed highly uneven across subtests from impaired to above average levels. On the Kaufman factors, Jonas had a peak in perceptual organization (IQ score 119), thus reflecting very strong visual attention skills, which together with normal to strong phonological abilities might underlie his excellent word reading. Finally, both his parents and teacher reported on other classroom-learning skills and difficulties.

Applying an ESSENCE framework to understanding adult autism spectrum disorder and ADHD: retrospective parent reports of childhood problems

Diagnoses of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are increasingly being made in adulthood. However, assessments can fail to address the diverse range of problems that patients have experienced. The current study applied an early symptomatic syndromes eliciting neurodevelopmental clinical examinations (ESSENCE) framework to explore retrospectively reported childhood developmental and behavioral problems. It examined if adult ASD and ADHD patients would show problems outside those reflected in the respective diagnostic criteria, and also if these patient groups would show more extensive childhood problems than other psychiatric patients. Parents of adults with ADHD (n = 130), ASD (n = 57), coexisting ADHD and ASD (n = 38), and other psychiatric disorders (n = 56) reported on a range of childhood problems. Descriptions of the ADHD, ASD, and ADHD+ASD groups reflected greater impairment than descriptions for patients with other psychiatric disorders in most problem areas. Although differences were observed between ADHD and ASD patients in the core diagnostic areas, these syndromes also shared a number of childhood difficulties. The ESSENCE approach can assist in understanding the symptom history of adult ADHD and ASD patients and can be helpful to distinguish their childhood experiences from other psychiatric patients' experiences.

Childhood clumsiness and peer victimization: a case-control study of psychiatric patients

BACKGROUND

Poor motor and social skills as well as peer victimization are commonly reported in both ADHD and autism spectrum disorder. Positive relationships between poor motor and poor social skills, and between poor social skills and peer victimization, are well documented, but the relationship between poor motor skills and peer victimization has not been studied in psychiatric populations.

METHOD

277 patients (133 males, 144 females), mean age 31 years, investigated for ADHD or autism spectrum disorder in adulthood and with normal intelligence, were interviewed about childhood peer victimization and examined for gross motor skills. The parents completed a comprehensive questionnaire on childhood problems, the Five to Fifteen. The Five to Fifteen is a validated questionnaire with 181 statements that covers various symptoms in childhood across eight different domains, one of them targeting motor skills. Regression models were used to evaluate the relationship between motor skills and the risk and duration of peer victimization, adjusted for sex and diagnosis.

RESULTS

Victims were described as more clumsy in childhood than their non-victimized counterparts. A significant independent association was found between reportedly poor childhood gross motor skills and peer victimization (adjusted odds ratio: 2.97 [95% confidence interval: 1.46-6.07], n = 235, p = 0.003). In adulthood, the victimized group performed worse on vertical jumps, a gross motor task, and were lonelier. Other factors that were expected to be associated with peer victimization were not found in this highly selected group.

CONCLUSION

Poor gross motor skills constitute a strong and independent risk factor for peer victimization in childhood, regardless of sex, childhood psychiatric care and diagnosis.

Internationally adopted children in Finland: parental evaluations of symptoms of reactive attachment disorder and learning difficulties - FINADO study

OBJECTIVE

This study investigated the association between psychological symptoms, such as features of reactive attachment disorder (RAD), and learning difficulties among international adoptees in Finland.

METHODS

The data for this study came from the FINnish ADOption (FINADO) study covering all internationally adopted children in Finland (n= 1450), with a response rate of 55.7%. The subsample consisted of 395 adopted children aged 9-15 (51.6% girls, 48.4% boys). Learning difficulties were evaluated by a screening questionnaire 'Five To Fifteen' and symptoms of RAD by FINADO RAD scale.

RESULTS

The parents estimated that one-third (33.4%) of the internationally adopted children had some, and 12.7% had severe learning difficulties, i.e. three and six times more than in normal population, respectively. RAD symptoms at the time of adoption were associated with learning difficulties at school age (OR 4.57, 95% CI 2.57-8.13).

CONCLUSIONS

Learning difficulties are common among internationally adopted children in Finland and symptoms of RAD are associated with a child's learning difficulties.

Developmental trajectories of early communication skills

PURPOSE

This study focused on developmental trajectories of prelinguistic communication skills and their connections to later parent-reported language difficulties.

METHOD

The participants represent a subset of a community-based sample of 508 children. Data include parent reports of prelinguistic communication skills at 12, 15, 18, and 21 months and language difficulties at age 4;7 (years;months). The authors used latent profile analysis to identify groups of children with differing developmental trajectories of prelinguistic communication skills ( n = 271). The relations among these groups and follow-up data of parent-reported concerns of language development ( n = 187), as well as the role of gender, were examined.

RESULTS

Six meaningful prelinguistic communication groups were identified with the latent profile analysis, and these groups showed connections to later parent-reported concerns of language difficulties. Delayed early expressive language and a minor delay of overall performance, together with symbolic difficulties, appeared as predictors of later language difficulties. Nearly 80% of the children whose parents reported language-related concerns at the follow-up stage could already be identified before their 2nd birthday.

CONCLUSION

The results support the potential of early screening in identifying children at risk of developing language difficulties, particularly when screening includes repeated surveillance of more than one area of communication skills.

Experiences of school bullying among internationally adopted children: results from the Finnish Adoption (FINADO) Study

This study investigated the prevalence of and factors associated with school bullying and victimization among Finnish international adoptees. The Olweus bully/victim questionnaire was sent to all 9-15-year-old children adopted in Finland between 1985 and 2007 through the mediating organizations officially approved by the Ministry of Social Affairs and Health. The children were identified through official adoption organizations. The response rate in the target sample was 49.4%: the study sample consisted of 364 children (190 girls, 52.2%). The children's background factors and symptoms of reactive attachment disorder (RAD) were evaluated using a FINADO questionnaire. Their learning difficulties and social and language skills were assessed using a standardized parental questionnaire (Five to Fifteen). Of the participants, 19.8% reported victimization by peers while 8% had bullied others. Both victimization and bullying were associated with severe symptoms of RAD at the time of adoption (RR 2.68, 95%CI 1.50-4.77 and RR 2.08, 95%CI 1.17-3.69 for victimization and bullying, respectively). Lack of social skills was associated with victimization (RR 1.74, 95%CI 1.06-2.85) but not independently with being a bully (RR 1.50, 95%CI 0.91-2.45). In a multivariate analysis the child's learning difficulties and language difficulties were not associated with either bullying others or victimization.

The Child and Adolescent Twin Study in Sweden (CATSS)

The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing longitudinal twin study targeting all twins born in Sweden since July 1, 1992. Since 2004, parents of twins are interviewed regarding the children's somatic and mental health and social environment in connection with their 9th or 12th birthdays (CATSS-9/12). By January 2010, 8,610 parental interviews concerning 17,220 twins had been completed, with an overall response rate of 80%. At age 15 (CATSS-15) and 18 (CATSS-18), twins and parents complete questionnaires that, in addition to assessments of somatic and mental health, include measures of personality development and psychosocial adaptation. Twin pairs in CATSS-9/12 with one or both twins screening positive for autism spectrum disorders, attention deficit/hyperactivity disorder, tic disorders, developmental coordination disorder, learning disorders, oppositional defiant disorder, conduct disorder, obsessive-compulsive disorder, and/or eating problems have been followed with in-depth questionnaires on family, social environment and personality, and subsequently by clinical assessments at age 15 together with randomly selected population controls, including 195 clinically assessed twin pairs from the first 2 year cohorts (CATSS-15/DOGSS). This article describes the cohorts and study groups, data collection, and measures used. Prevalences, distributions, heritability estimates, ages at onset, and sex differences of mental health problems in the CATSS-9/12, that were analyzed and found to be overall comparable to those of other clinical and epidemiological studies. The CATSS study has the potential of answering important questions on the etiology of childhood mental health problems and their role in the development of later adjustment problems.

An efficacy study of a combined parent and teacher management training programme for children with ADHD

BACKGROUND

Several parent training programmes and behavioural teacher training programmes built on learning theory have been developed for problem prevention and treatment of attention-deficit/hyperactivity disorder (ADHD) and/or oppositional defiant disorder (ODD) during the last few decades. Group format has often been used for parent training but single-subject designs are more common in teacher training. More studies have focussed on pre-school children than on older children, and a minority have been conducted in public mental health settings.

AIM

This study aimed to evaluate a combined parent and teacher manual-based group training programme for children with ADHD conducted by the staff at a child and adolescent psychiatric clinic in Sweden.

METHOD

The intervention was a modified version of Barkley's programme. Children were randomized to an Intervention or a Control group. Sixty-one parents and 68 teachers answered questions about ADHD and ODD symptoms, and about behavioural problems when the study started and at a 3-month follow-up.

RESULTS

RESULTS showed that the intervention resulted in a reduction of the number of children who met DSM-IV criteria for ADHD and/or ODD. Effects were more pronounced in the home setting than in the school setting, and were further accentuated when both parents and teachers of the same child took part in the intervention. Teachers with more problematic classroom situations benefited most from the intervention.

CONCLUSION

The programme, "Strategies in Everyday Life", has, in a regular clinical setting, demonstrated promising effects on children's disruptive behaviour, and a clinical implication was to recommend involving both parents and teachers in the programme.

Maternal pre- and postnatal mental health trajectories and child mental health and development

Pregnancy and early motherhood involve uncertainty and change, which can evoke mental health problems. We identified maternal mental health trajectories in pre- and postnatal period, and examined their association with later child mental health and development. Finnish mothers reported psychological distress (General Health Questionnaire [GHQ-36]) and depressive (Beck Depression Inventory [BDI-13]) symptoms in pregnancy (T1; N = 788) and two months (T2; N = 657) and 12 months (T3; N = 545) postpartum. Both parents accounted their child’s mental health (Behavior Assessment System for Children [BASC]) and social (Social Skills Rating System [SSRS], Child Behavior Scale [CBS]) and cognitive development (Five to Fifteen [FTF]) when the child was 7–8 years old (T4; N = 485). We identified five trajectories depicting unique timing and course of maternal mental health from pregnancy into 1 year of mothering: Stable low levels of mental health symptoms (75%) and prenatal (6%), early postpartum (9%) and late postpartum (6%) mental health problems. The fifth trajectory, heterogeneous high levels of mental health problems (4%) was an unclassified post hoc class, combining mothers with chronic high or highly variable mental health profiles. Results show some trajectory-related timing effects on children’s mental health and cognitive development. The trajectories of early postpartum and heterogeneous high levels of mental health problems predicted higher level of internalizing symptoms as compared to stable low-levels trajectory. The heterogeneous high-levels trajectory predicted higher levels of problems in executive functions than the stable low and late postpartum trajectories, and in memory tasks than children in other trajectories. We discuss the timing and course of maternal mental health from the viewpoint of infant and child development.

Atypical acquisition and atypical expression of memory consolidation gains in a motor skill in young female adults with ADHD

Individuals with ADHD often show performance deficits in motor tasks. It is not clear, however, whether this reflects less effective acquisition of skill (procedural knowledge), or deficient consolidation into long-term memory, in ADHD. The aim of the study was to compare the acquisition of skilled motor performance, the expression of delayed--consolidation phase--gains and retention, in persons with and without ADHD. Thirty-two participants, 16 with ADHD, were trained on a sequence of finger movements using a well-established training protocol, and tested before training and immediately, 24h and 2 weeks after training. Both groups showed similar within-session gains in speed; additional, delayed gains were expressed at 24h, but less robustly in ADHD, and at 2 weeks post-training. However, while controls showed significant delayed gains in accuracy at 24h and 2 weeks post-training, accuracy deteriorated in ADHD from pre-training to 24h post-training and was only at pre-training levels by 2-weeks post-training. Our results demonstrate a latent memory consolidation phase in motor sequence learning, expressed as delayed gains in speed and a much delayed recovery of pre-training accuracy, in individuals with ADHD. However, both the acquisition and memory consolidation of motor skills are atypical in ADHD.

Gender differences on the Five to Fifteen questionnaire in a non-referred sample with inattention and hyperactivity-impulsivity and a clinic-referred sample with hyperkinetic disorder

The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non-referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity-impulsivity and then clinic-referred girls (n = 35) and boys (n = 66) with hyperkinetic disorder (HKD) were compared on the FTF. Results suggested that non-referred boys were more hyperactive-impulsive than non-referred girls, whereas clinic-referred boys and girl with HKD were more similar than dissimilar on the FTF questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic-referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire.

Teacher reports of hypoactivity symptoms reflect slow cognitive processing speed in primary school children

The mediating effect of cognitive processing speed on the ability of a primary school child to achieve his/her full potential of intellectual functioning emphasizes the importance of methods to detect "slow" children. Primary school teachers may be the first to have concerns about inattentive pupils who show symptoms of hypoactivity, but may find the symptoms difficult to interpret. In the present study we ask if a primary school teacher's report of hypoactivity symptoms can be explained by the child's performance on tests of processing speed. The 255 children included in the present study were part of the first wave of the Bergen Child Study, in which teachers completed a questionnaire including two hypoactivity items from the Five to Fifteen (FTF) questionnaire. Processing speed was measured by the Processing Speed Index (PSI) from the WISC-III, 1-2 years after the teacher rating. Teachers reported "certainly true" on at least one FTF item of hypoactivity for 11.8% of the children. These children obtained lower scores on the PSI than the remaining children in the sample. The PSI accounted for a considerable proportion of the variance of teacher reports on the FTF item "difficulty getting started on a task/activity". The risk of a PSI score below 85 was increased in children with teacher-reported hypoactivity symptoms. The results indicate that teacher reports of hypoactivity symptoms reflect slow cognitive processing speed and should be followed up by a psychometric examination. Still, future studies are needed to improve detection and treatment of children with slow processing speed.

Attention Deficit Hyperactivity Disorder (ADHD) among longer-term prison inmates is a prevalent, persistent and disabling disorder

BACKGROUND

ADHD is a common and disabling disorder, with an increased risk for coexisting disorders, substance abuse and delinquency. In the present study, we aimed at exploring ADHD and criminality. We estimated the prevalence of ADHD among longer-term prison inmates, described symptoms and cognitive functioning, and compared findings with ADHD among psychiatric outpatients and healthy controls.

METHODS

At Norrtälje Prison, we approached 315 male inmates for screening of childhood ADHD by the Wender Utah Rating Scale (WURS-25) and for present ADHD by the Adult ADHD Self-Report Screener (ASRS-Screener). The response rate was 62%. Further, we assessed 34 inmates for ADHD and coexisting disorders. Finally, we compared findings with 20 adult males with ADHD, assessed at a psychiatric outpatient clinic and 18 healthy controls.

RESULTS

The estimated prevalence of adult ADHD among longer-term inmates was 40%. Only 2 out of 30 prison inmates confirmed with ADHD had received a diagnosis of ADHD during childhood, despite most needed health services and educational support. All subjects reported lifetime substance use disorder (SUD) where amphetamine was the most common drug. Mood and anxiety disorders were present among half of subjects; autism spectrum disorder (ASD) among one fourth and psychopathy among one tenth. Personality disorders were common; almost all inmates presented conduct disorder (CD) before antisocial personality disorder (APD). Prison inmates reported more ADHD symptoms during both childhood and adulthood, compared with ADHD psychiatric outpatients. Further, analysis of executive functions after controlling for IQ showed both ADHD groups performed poorer than controls on working memory tests. Besides, on a continuous performance test, the ADHD prison group displayed poorer results compared with both other groups.

CONCLUSIONS

This study suggested ADHD to be present among 40% of adult male longer-term prison inmates. Further, ADHD and coexisting disorders, such as SUD, ASD, personality disorders, mood- and anxiety disorders, severely affected prison inmates with ADHD. Besides, inmates showed poorer executive functions also when controlling for estimated IQ compared with ADHD among psychiatric outpatients and controls. Our findings imply the need for considering these severities when designing treatment programmes for prison inmates with ADHD.

Development and behaviour of 5-year-old very low birthweight infants

The place and time of birth influence the mortality of premature infants. We studied the effect of prematurity, time of birth, birth hospital level and district on the development and behaviour in a national cohort of 5-year-old Finnish very low birthweight infants (VLBWI). All surviving VLBWI (gestational age <32 weeks or birthweight <or=1,500 g) born in 2001-2002 in level II or III hospitals in Finland and full-term controls were included. The parents of 588 (64%) VLBWI and 176 (46%) controls returned the Five to Fifteen questionnaire (FTF) on the development and behaviour of their 5-year-old children. The questionnaire scores were linked to data from the National Medical Birth Register, the Hospital Discharge Register, the Register of Congenital Malformations and the Cause of Death Register. VLBWI had lower developmental and behavioural scores compared to the controls in all FTF domains. In VLBWI, the scores were less optimal, the lower the gestational age was. The time of birth, birth hospital level and district were not associated with the developmental and behavioural scores in VLBWI. In conclusion, short duration of pregnancy adversely influences development and behaviour in VLBWI. Despite differences previously demonstrated in mortality related to time and place of birth, there were no differences in developmental and behavioural scores in VLBWI according to the time of birth, birth hospital level or district. Thus, the survival advantage in level III hospitals seems not to be gained at the expense of behavioural or developmental problems.

Relations between brain volumes, neuropsychological assessment and parental questionnaire in prematurely born children

The objective of this study is to assess the relationship between brain volumes at term equivalent age and neuropsychological functions at 5 years of age in very low birth weight (VLBW) children, and to compare the results from a neuropsychological assessment and a parental questionnaire at 5 years of age. The study group included a regional cohort of 97 VLBW children and a control group of 161 children born at term. At term equivalent age, brain magnetic resonance imaging (MRI) was performed on the VLBW children, and analysed for total and regional brain volumes. At 5 years of age, a psychologist assessed the neuropsychological performance with NEPSY II, and parents completed the Five to fifteen (FTF) questionnaire on development and behaviour. The results of the control group were used to give the age-specific reference values. No significant associations were found between the brain volumes and the NEPSY II domains. As for the FTF, significant associations were found between a smaller total brain tissue volume and poorer executive functions, between a smaller cerebellar volume and both poorer executive functions and motor skills, and, surprisingly, between a larger volume of brainstem and poorer language functions. Even after adjustment for total brain tissue volume, the two associations between the cerebellar volume and the FTF domains remained borderline significant (P = 0.05). The NEPSY II domains Executive Functioning, Language and Motor Skills were significantly associated with the corresponding FTF domains. In conclusion, altered brain volumes at term equivalent age appear to affect development still at 5 years of age. The FTF seems to be a good instrument when used in combination with other neuropsychological assessment.

The autism--tics, AD/HD and other comorbidities inventory (A-TAC): further validation of a telephone interview for epidemiological research

BACKGROUND

Reliable, valid, and easy-to-administer instruments to identify possible caseness and to provide proxies for clinical diagnoses are needed in epidemiological research on child and adolescent mental health.The aim of this study is to provide further validity data for a parent telephone interview focused on Autism--Tics, Attention-deficit/hyperactivity disorder (AD/HD), and other Comorbidities (A-TAC), for which reliability and preliminary validation data have been previously reported.

METHODS

Parents of 91 children clinically diagnosed at a specialized Child Neuropsychiatric Clinic, 366 control children and 319 children for whom clinical diagnoses had been previously assigned were interviewed by the A-TAC over the phone. Interviewers were blind to clinical information. Different scores from the A-TAC were compared to the diagnostic outcome.

RESULTS

Areas under ROC curves for interview scores as predictors of clinical diagnoses were around 0.95 for most disorders, including autism spectrum disorders (ASDs), attention deficit/hyperactivity disorder (AD/HD), tic disorders, developmental coordination disorders (DCD) and learning disorders, indicating excellent screening properties. Screening cut-off scores with sensitivities above 0.90 (0.95 for ASD and AD/HD) were established for most conditions, as well as cut-off scores to identify proxies to clinical diagnoses with specificities above 0.90 (0.95 for ASD and AD/HD).

CONCLUSIONS

The previously reported validity of the A-TAC was supported by this larger replication study using broader scales from the A-TAC-items and a larger number of diagnostic categories. Short versions of algorithms worked as well as larger. Different cut-off levels for screening versus identifying proxies for clinical diagnoses are warranted. Data on the validity for mood problems and oppositional defiant/conduct problems are still lacking. Although the A-TAC is principally intended for epidemiological research and general investigations, the instrument may be useful as a tool to collect information in clinical practice as well.

Atomoxetine improves patient and family coping in attention deficit/hyperactivity disorder: a randomized, double-blind, placebo-controlled study in Swedish children and adolescents

This 10-week study assessed the efficacy of atomoxetine in combination with psychoeducation compared to placebo and psychoeducation in the improvement of Quality of Life in Swedish stimulant-naive children and adolescents with attention deficit/hyperactivity disorder. A total of 99 patients were treated with atomoxetine (49 patients) or placebo (50 patients) for 10 weeks and assessed regarding broader areas of functioning using the Quality of Life measures Child Health and Illness Profile-Child Edition (CHIP-CE), Family Strain Index [FSI; equivalent to the Family Burden of Illness Module used in the study], Appraisal of Stress in Child-Rearing (ASCR), Five to fifteen (FTF), "I think I am" ("Jag tycker jag är"), and Children's Depression Rating Scale-Revised (CDRS-R) before and after the active treatment phase. Simultaneously, the patients' parents participated in a 4-session psychoeducation program. A statistically significant difference in favor of atomoxetine was seen in the improvement from baseline to study endpoint for the CHIP-CE domains "Achievement" and "Risk avoidance", for the FSI total score, for the ASCR section (I) domain "Child as a burden", for all FTF domains except for "Language and Speech", and for the CDRS-R total score. No difference between treatment groups was observed in the patient-assessed evaluation of self-esteem using the "I think I am" scale. Atomoxetine combined with psychoeducation had a positive effect on various everyday coping abilities of the patients as well as their families during 10 weeks of treatment, whereas the patients' self-image and the parents' image of the climate in the family were not significantly improved.

Psychiatric and psychosocial problems in adults with normal-intelligence autism spectrum disorders

BACKGROUND

Individuals with autism spectrum disorders (ASDs) often display symptoms from other diagnostic categories. Studies of clinical and psychosocial outcome in adult patients with ASDs without concomitant intellectual disability are few. The objective of this paper is to describe the clinical psychiatric presentation and important outcome measures of a large group of normal-intelligence adult patients with ASDs.

METHODS

Autistic symptomatology according to the DSM-IV-criteria and the Gillberg & Gillberg research criteria, patterns of comorbid psychopathology and psychosocial outcome were assessed in 122 consecutively referred adults with normal intelligence ASDs. The subjects consisted of 5 patients with autistic disorder (AD), 67 with Asperger's disorder (AS) and 50 with pervasive developmental disorder not otherwise specified (PDD NOS). This study group consists of subjects pooled from two studies with highly similar protocols, all seen on an outpatient basis by one of three clinicians.

RESULTS

Core autistic symptoms were highly prevalent in all ASD subgroups. Though AD subjects had the most pervasive problems, restrictions in non-verbal communication were common across all three subgroups and, contrary to current DSM criteria, so were verbal communication deficits. Lifetime psychiatric axis I comorbidity was very common, most notably mood and anxiety disorders, but also ADHD and psychotic disorders. The frequency of these diagnoses did not differ between the ASD subgroups or between males and females. Antisocial personality disorder and substance abuse were more common in the PDD NOS group. Of all subjects, few led an independent life and very few had ever had a long-term relationship. Female subjects more often reported having been bullied at school than male subjects.

CONCLUSION

ASDs are clinical syndromes characterized by impaired social interaction and non-verbal communication in adulthood as well as in childhood. They also carry a high risk for co-existing mental health problems from a broad spectrum of disorders and for unfavourable psychosocial life circumstances. For the next revision of DSM, our findings especially stress the importance of careful examination of the exclusion criterion for adult patients with ASDs.

Chronic conditions, functional limitations, and special health care needs in 10- to 12-year-old children born at 23 to 25 weeks' gestation in the 1990s: a Swedish national prospective follow-up study

BACKGROUND

Children born extremely immature (gestational age < 26 weeks' gestation) increasingly reach school age. Information on their overall functioning and special health care needs is necessary to plan for their medical and educational services. This study was undertaken to examine neurosensory, medical, and developmental conditions together with functional limitations and special health care needs of extremely immature children compared with control subjects born at term.

METHODS

We studied 11-year-old children born before 26 completed weeks of gestation in all of Sweden from 1990 through 1992. All had been evaluated at 36 months' corrected age. Identification of children with chronic conditions lasting > or = 12 months was based on a questionnaire administered to parents. Neurosensory impairments were identified by reviewing health records. Information regarding other specific medical diagnoses and developmental disabilities was obtained by standard parent and teacher questionnaires.

RESULTS

Of 89 eligible children, 86 (97%) were studied at a mean age of 11 years. An equal number of children born at term served as controls. Logistic-regression analyses adjusting for social risk factors and gender showed that significantly more extremely immature children than controls had chronic conditions, including functional limitations (64% vs 11%, respectively), compensatory dependency needs (59% vs 25%), and services above those routinely required by children (67% vs 22%). Specific diagnoses or disabilities with higher rates in extremely immature children than in controls included neurosensory impairment (15% vs 2%), asthma (20% vs 6%), poor motor skills of > 2 SDs above the mean (26% vs 3%), poor visual perception of > 2 SDs above the mean (21% vs 4%), poor learning skills of > 2 SDs above the mean (27% vs 3%), poor adaptive functioning with T scores of < 40 (42% vs 9%), and poor academic performance with T score < 40 (49% vs 7%).

CONCLUSIONS

Children born extremely immature have significantly greater health problems and special health care needs at 11 years of age. However, few children have severe impairments that curtail major activities of daily living.

Neuropsychiatric and neurodevelopmental outcome of children at age 6 and 7 years who screened positive for language problems at 30 months

We present a prospective study at school age of neuropsychiatric and neurodevelopmental outcome of language delay suspected at child health screening around 30 months of age. In a community sample, 25 children (21 males, 4 females) screening positive and 80 children (38 males, 42 females) screening negative for speech and language problems at age 30 months were examined in detail for language disorders at age 6 years. The screen-positive children were then followed for another year and underwent in-depth neuropsychiatric examination by assessors blind to the results of previous testing. Detailed follow-up results at age 7 years were available for 21 children. Thirteen of these 21 children (62%) had a major neuropsychiatric diagnosis (autism, atypical autism, Asperger's syndrome, attention-deficit-hyperactivity disorder [ADHD]), or combinations of these. Two further children (10%) had borderline IQ with no other major diagnosis. We conclude that children in the general population who screen positive for speech and language problems before age 3 years appear to be at very high risk of autism spectrum disorders or ADHD, or both, at 7 years of age. Remaining language problems at age 6 years strongly predict the presence of neuropsychiatric or neurodevelopmental disorders at age 7 years.

ADHD and language impairment: A study of the parent questionnaire FTF (Five to Fifteen)

The parental questionnaire FTF (Five to Fifteen) was given to parents of 76 children (mean age 11 years) diagnosed with ADHD. About half of the children had at least once been referred to a speech- and language pathologist. Most of them had not received any intervention or follow-up. A factor analysis identified six problem areas, which explain close to 75% of the total variation: Cognitive Skills, Motor/Perception, Emotion/Socialisation/Behaviour, Attention, Literacy Skills and Activity Control. The majority of the children had pragmatic problems, which are associated with some of the core aspects of the ADHD symptoms, especially inattention and impulsiveness. Communication and language comprehension caused these children many more problems than expressive language. Problems of reading and writing were very frequent. IQ-score was associated with maths and reading/writing. Additional items reflecting language skills, in particular language comprehension and pragmatics, were also found in other domains in the FTF, mainly in Executive functions, Learning and Social skills. Problems with language and pragmatics thus seem to be associated with the typical problems with learning and social skills in children with ADHD.

Psychiatric telephone interview with parents for screening of childhood autism - tics, attention-deficit hyperactivity disorder and other comorbidities (A-TAC): preliminary reliability and validity

BACKGROUND

Reliable, valid and easily administered screening instruments would greatly facilitate large-scale neuropsychiatric research.

AIMS

To test a parent telephone interview focused on autism - tics, attention-deficit hyperactivity disorder (ADHD) and other comorbidities (A-TAC).

METHOD

Parents of 84 children in contact with a child neuropsychiatric clinic and 27 control children were interviewed. Validity and interrater and test - retest reliability were assessed.

RESULTS

Interrater and test - retest reliability were very good. Areas under receiver operating characteristics curves between interview scores and clinical diagnoses were around 0.90 for ADHD and autistic spectrum disorders, and above 0.70 for tics, learning disorders and developmental coordination disorder. Using optimal cut-off scores for autistic spectrum disorder and ADHD, good to excellent kappa levels for interviews and clinical diagnoses were noted.

CONCLUSIONS

The A-TAC appears to be a reliable and valid instrument for identifying autistic spectrum disorder, ADHD, tics, learning disorders and developmental coordination disorder.

Screening of developmental disorders in five-year-olds using the FTF (Five to Fifteen) questionnaire: a validation study

The study examined the validity of the Five to Fifteen (FTF) questionnaire in detecting developmental disorders in five-year-old children. A pilot study (N=70) was first undertaken to try out a translation of the FTF into Finnish. Subsequently, FTF questionnaires were mailed to parents of all five-year-old children from specified health-care districts in Vantaa, Finland. A total of 769 questionnaires (60%) were completed and returned. Children scoring above a cut-off value in any domain were considered at risk for having developmental disorders (the Risk Group; N=90). A Control Group was formed by randomly selecting 30 children who did not score above the threshold value in any domain. The children from the Risk Group and the Control Group were called to individual neuropsychological assessments. All invited children attended the assessments. The parts of the FTF that assess fine motor skills, executive functions (including attention and impulsivity), perception, memory, and language were used for this study. The external criterion measure was the NEPSY, a neuropsychological assessment instrument. Results demonstrated that the five FTF Domain Scores used in this study correlated significantly with the corresponding NEPSY Domain Scores. Second, the Risk Group obtained significantly poorer scores on the NEPSY than the Control Group. Third, on a cross-tabulation a very high rate of positive hits (93 %) was obtained as well as a very low rate of misses (7 %), indicating a very good sensitivity. However, there were a large percentage of false positives (63 %), indicating that specificity was not so good. Evidently, parents may report concerns related to the young child's development even when neuropsychological assessments do not indicate significant disorders. On the whole, the findings supported the validity of the FTF as a developmental screening instrument.

Behavioural problems and psychiatric symptoms in 5-13 year-old Swedish children-a comparison of parent ratings on the FTF (Five to Fifteen) with the ratings on CBCL (Child Behavior Checklist)

As part of the validation procedure of a new parent questionnaire ("Five to Fifteen" or the FTF) a random sample of 1500 children aged 5-13 years from the Swedish Population Register (SPAR) was approached. The FTF and the Child Behavior Checklist (CBCL) were sent to the parents of the children together with questions about background conditions. After two reminders the response rate was 55.6%. The final sample had a mean age of 9.12 years (SD=1.89) and a sex distribution with 55% boys and 45% girls. Analysis of attrition did not support overrepresentation of foreigners/immigrants in the attrition population. FTF like CBCL showed sensitivity to sociodemographic variables. On the FTF fewer problems were indicated for girls in all domain scales, whereas this was true for the summary scale Externalizing and Mixed problems of the CBCL. The effects of age and area of residence were slight, but parental education was negatively related to all domain scales of the FTF and to all the CBCL scales. The intercorrelations of the FTF and CBCL scales with common content showed substantial overlap supporting the validity of the FTF scales. The correlation between scales within the FTF however also indicates a substantial comorbidity. This is also supported by the substantial correlation between problem score of the FTF domains perception, language, motor skills and the CBCL scale scores Attention, Social problems as well as the summary scale Mixed problems. These findings indicate that problems with inattention and social relations are shared across the various problem domains. Factor analysis of the FTF subdomain scores resulted in two factors, one representing learning problems and the other behavioural/emotional problems. Despite the low response rate the representativity of the sample was supported by the fact that the total problem score of CBCL was very similar to that of another Swedish sample with a relatively high response rate. The finding of a frequency of AD/HD symptoms in the FTF rating corresponding to the figures of prevalence of AD/HD in several international epidemiological studies could also be seen as support for the relevance of the findings. Thus, the results give support to the usefulness of the FTF questionnaire as an instrument that can help in delineating specific problem areas within the field of child neuropsychiatry. Through the comparison with the CBCL the validity of the FTF for the parts that the two instruments share could be ascertained and the value of tapping a broader problem area could be elucidated.
