    • BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for the closure of unilateral cleft lip and palate, and randomised trials have only rarely been performed. This paper is an introduction to three randomised trials of primary surgery for children born with complete unilateral cleft lip and palate (UCLP). It presents the protocol developed for the trials in CONSORT format, and describes the management structure that was developed to achieve the long-term engagement and commitment required to complete the project.METHOD: Ten established national or regional cleft centres participated. Lip and soft palate closure at 3-4 months, and hard palate closure at 12 months served as a common method in each trial. Trial 1 compared this with hard palate closure at 36 months. Trial 2 compared it with lip closure at 3-4 months and hard and soft palate closure at 12 months. Trial 3 compared it with lip and hard palate closure at 3-4 months and soft palate closure at 12 months. The primary outcomes were speech and dentofacial development, with a series of perioperative and longer-term secondary outcomes.RESULTS: Recruitment of 448 infants took place over a 9-year period, with 99.8% subsequent retention at 5 years.CONCLUSION: The series of reports that follow this introductory paper include comparisons at age 5 of surgical outcomes, speech outcomes, measures of dentofacial development and appearance, and parental satisfaction. The outcomes recorded and the numbers analysed for each outcome and time point are described in the series.TRIAL REGISTRATION: ISRCTN29932826.

  • Child neurodevelopmental and behavioural problems are intercorrelated and dimensionally distributed in the general population
  • 2008

    • The Autism – Tics, AD/HD, and other Comorbidities inventory (A-TAC) is a comprehensive interview for evaluating problems related to autism spectrum disorders (ASD), tic disorders, attention-deficit/hyperactivity disorder (AD/HD), and common comorbid conditions in children and adolescents. A-TAC telephone interviews were administered to parents of 2,957 children aged nine- or twelve-years, representing one in each twin pair included in the population- based Child and Adolescent Twin Study in Sweden (CATSS). A total of 16.4% were screen-positive for one or several of the targeted disorder, 1.3% for ASD and 5.6% for AD/HD. All types of problems were more common among boys, with the exception of those related to “eating habits”. They were all dimensionally/continuously distributed, highly inter-correlated, and overlapped across types. They aggregated in three ba- sic factors corresponding to externalizing/disruptiveness, socio-communicative problems, and compulsiveness. Population-based data on problems in children thus challenge current categorical diagnostic definitions, calling for dimen- sional and complementary models of problem descriptions.

  • The impact of ADHD and autism spectrum disorders on temperament, character, and personality development.
  • 2006
  • Ingår i: The American Journal of Psychiatry. - 0002-953X .- 1535-7228. ; 163:7, s. 1239-1244
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The authors describe personality development and disorders in relation to symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders. METHOD: Consecutive adults referred for neuropsychiatric investigation (N=240) were assessed for current and lifetime ADHD and autism spectrum disorders and completed the Temperament and Character Inventory. In a subgroup of subjects (N=174), presence of axis II personality disorders was also assessed with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). RESULTS: Patients with ADHD reported high novelty seeking and high harm avoidance. Patients with autism spectrum disorders reported low novelty seeking, low reward dependence, and high harm avoidance. Character scores (self-directedness and cooperativeness) were extremely low among subjects with neuropsychiatric disorders, indicating a high overall prevalence of personality disorders, which was confirmed with the SCID-II. Cluster B personality disorders were more common in subjects with ADHD, while cluster A and C disorders were more common in those with autism spectrum disorders. The overlap between DSM-IV personality disorder categories was high, and they seem less clinically useful in this context. CONCLUSIONS: ADHD and autism spectrum disorders are associated with specific temperament configurations and an increased risk of personality disorders and deficits in character maturation.

  • The Autism--Tics, AD/HD and other Comorbidities (A-TAC) telephone interview: convergence with the Child Behavior Checklist (CBCL).
  • 2010
  • Ingår i: Nordic Journal of Psychiatry. - : Informa UK Limited. - 0803-9488 .- 1502-4725. ; 64:3, s. 218-224
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To compare telephone interview screening for child psychiatric/neuropsychiatric disorders using the inventory of Autism-Tics, Attention deficit/hyperactivity disorder (AD/HD) and other Comorbidities (A-TAC) with results from the Child Behavior Checklist (CBCL). Background: The A-TAC is a parent telephone interview focusing on autism spectrum disorders (ASDs) and co-existing problems, developed for lay interviewers. Subjects and methods: A-TAC telephone interviews and CBCL questionnaires were obtained from parents of 106 Swedish twin pairs aged 9 and 12 years. Results: Correlations between A-TAC modules and CBCL scales aimed at measuring similar concepts were generally significant albeit modest, with correlation coefficients ranging from 0.30 through 0.55. Conclusion: The A-TAC has convergent validity with the CBCL in several problem areas, but the A-TAC also provides more detailed and specific assessments of ASD symptoms and related neuropsychiatric problems.

  • The Swedish version of the parent-rated Junior Temperament and Character Inventory (J-TCI).
  • 2010
  • Ingår i: Psychological reports. - 0033-2941. ; 107:3, s. 715-25
  • Tidskriftsartikel (refereegranskat)abstract
    • To evaluate the psychometric characteristics of the Swedish version of the Junior Temperament and Character Inventory (J-TCI), it was sent to parents of 9- and 12-yr.-old twins in Sweden. The final number of responders was 196 parents who rated 92 female and 104 male twin pairs. The inventory of one twin, randomly chosen from each pair, was included in the analyses. Reward Dependence, Persistence, and Cooperativeness were scored higher in girls; Novelty Seeking was higher in the 9-yr.-olds and Persistence in the 12-yr.-olds. Pearson's correlations showed that some dimensions were not statistically independent from each other, even if the covariance was moderate. Internal consistency (Cronbach's alpha) was satisfactory for Harm Avoidance, Novelty Seeking, Self-Directedness, and Cooperativeness (.68-.81), while it was lower in those dimensions that had fewer items. The Swedish parent version of the J-TCI shared about the same psychometric characteristics as found in international samples.

  • The autism--tics, AD/HD and other comorbidities inventory (A-TAC): further validation of a telephone interview for epidemiological research.
  • 2010
  • Ingår i: BMC Psychiatry. - 1471-244X. ; 10
  • Tidskriftsartikel (refereegranskat)abstract
    • ABSTRACT: 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.

  • Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 2. Surgical results
  • 2017
  • Ingår i: Journal of Plastic Surgery and Hand Surgery. - : TAYLOR & FRANCIS LTD. - 2000-656X .- 2000-6764. ; 51:1, s. 14-20
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Longstanding uncertainty surrounds the selection of surgical protocols for unilateral cleft lip and palate, and randomised trials have only rarely been performed. The Scandcleft Project consists of three trials commenced in 1997 involving ten centres in Denmark, Finland, Norway, Sweden, and the UK. Three groups of centres tested a newly-defined common technique for palatal repair (Arm A) against their local protocols (Arms B, C, D). Arm A was familiar to most of the surgeons in Trial 1, but not to the surgeons in the other Trials. Aim: To evaluate surgical events and complications of the 448 (293 boys, 155 girls) patients with complete unilateral cleft lip and palate (UCLP) enrolled in the three trials. Method: The three trials were carried out in parallel in adherence with a fully developed, ethically approved protocol. Operative time, bleeding, complications, and major dehiscence during and after both primary surgeries were recorded by the surgeon. Rates of fistula and surgery for velopharyngeal incompetence (VPI) were assessed until the youngest patient of the study had reached the age of 9 years. Pearson Chi-square statistical analysis was used to compare the outcomes. Results: No significant differences in bleeding, infection, anaesthetic complications or length of hospital stay between the different arms were found for Trial 1. However, in Trials 2 and 3 there were more airway problems in Arm A than with the traditional local protocols (Arms C or D). In Trial 3 fistula and VPI surgery rates were also higher in Arm A. Conclusions: The results do not provide statistical evidence that any technique is better than others, but indicate that surgery was more problematic for surgeons who were still gaining experience with an unfamiliar surgical protocol.
