RESUMEN
The present study aimed to: (a) identify latent class trajectories of OCD-related functional impairment, before, during and over three years after stepped-care treatment in children and adolescents with OCD; (b) describe these classes according to pretreatment characteristics; (c) identify predictors of trajectory class membership and (d) examine the relationship of functional impairment trajectory classes with OCD symptom severity trajectory classes. The sample consisted of 266 children and adolescents (aged 7-17 years) with OCD, participating in the Nordic long-term OCD treatment study. Latent class growth analysis was conducted using Child Obsessive-Compulsive Impact Scale-Revised (COIS-R) data from children and parents on seven assessment points over a three-year period. A 3-class solution was identified. The largest class (70.7%) initiated treatment with lower functional impairment and obtained moderate reduction which was maintained over time. The second class (24.4%) initiated with higher functional impairment which rapidly diminished over time. The third and smallest class (4.9%), initiated with moderate functional impairment which remained stable over time. The classes differed on measures of OCD severity and comorbid symptoms. Most participants improved with treatment and maintained low levels of impairment. However, a subgroup distinguished by higher levels of ADHD symptoms, remained at pretreatment levels of impairment throughout.

PRIMARY OBJECTIVES: To assess long-term effects of early traumatic brain injury (TBI) on mental health, cognition, behaviour and adjustment and to identify prognostic factors. METHODS AND PROCEDURES: A 1-year nationwide cohort of all 0-19 year old Icelandic children and adolescents diagnosed with TBI in 1992-1993 (n = 550) received a questionnaire with clinical outcome scales and questions on TBI and socio-economic status (SES) by mail â¼16 years post-injury. A control group (n = 1232), newly selected from the National Registry, received the same questionnaire. Non-respondents answered a shorter version by telephone. Overall participation was 67%. MAIN OUTCOMES AND RESULTS: Medically confirmed and self-reported TBI was reflected in worse outcome. Force of impact, number and severity of TBIs predicted poorer results. Parental SES and demographic factors had limited effects. Not reporting early, medically confirmed TBI did not exclude cognitive sequelae. In self-reported disability, absence of evaluation for compensation was not linked to outcome. CONCLUSIONS: Clinical outcome was consistent with late complaints attributed to early TBI. TBI-related variables had greater prognostic value than other factors. Self-reporting of TBI sustained very early in life needs supplementary information from parents and medical records. More consistency in compensation evaluations following paediatric TBI is indicated.

PRIMARY OBJECTIVES: To examine the scope of paediatric traumatic brain injury (TBI) as a health concern and to identify prognostic factors for TBI-related sequelae. METHODS AND PROCEDURES: The study was prospective and nationwide. A questionnaire was sent to a study group (SG) of all 0-19 years old in Iceland, diagnosed â¼16 years earlier with TBI during a 1-year period, 1992-1993 (n = 550) and to a control group (CG) (n = 1232), selected from the National Register. MAIN OUTCOMES AND RESULTS: In the CG 49.5% reported having sustained TBI and 7.0% reported long-term disability. In the group with TBI, force of impact to the head, more than one incident of TBI and the injury severity by gender interaction predicted late symptoms. TBI severity had substantially less effect than force of impact and was close to non-existent for females. CONCLUSIONS: Based on two independent nationwide samples, the scope of TBI as a health concern in adolescence and young adulthood is greater than previously documented. The findings suggest that TBI event-related factors, especially force of impact, have greater predictive value than clinical symptoms of severity at the acute stage, females being more sensitive to the effects of mild TBI than males.

Diagnostic information on adolescents may be elicited from both youths and their parents, especially for depressive and suicidal symptomatology. The objective of this study was to examine the degree of agreement between parent and adolescent reports of major psychiatric disorders, at the diagnostic and at the symptom level, in a severely affected inpatient clinical population. 64 parent-adolescent pairs were interviewed separately with the semi-structured diagnostic interview Kiddie-SADS-PL. Symptomatology was also assessed with 11 self-report and parent-report scales, all translated, adapted and in most cases validated in Iceland. A total of 25 subscales were included to assess emotional dimensions such as depression or anxiety and cognitive dimensions such as attention deficit or self-concept. Good agreement was found for social phobia and fair agreement for generalized anxiety disorder. Although parent-youth agreement was poor in most cases at the symptoms level, significant correlations indicated consistency for most severity scores, except those related to depressive symptomatology, attention deficit, separation anxiety or conduct disorder. The low agreement between reports of suicidal ideation is in line with results from previous studies and suggests that parents might under- or over-estimate this symptomatology. The combination of data obtained with diagnostic interviews and rating-scales confirmed results from prior empirical work, giving greater weight to parents' reports of observable behavior and to adolescents' reports of subjective experiences, especially depressive symptomatology. Our findings suggest that both parent and child informants are necessary to obtain adequate assessments in adolescents. Further research should explore the correspondence between discrepant diagnoses and external criteria such as parental psychopathology or parent-child relationships and attachment. Psychoanalysis could benefit from cognitive neuroscience and use cognitive assessments as interesting tools. Thus, cognitive assessments can show discrepant results according to parents' or adolescents' reports and can therefore shed light on the parent-child interaction and relational dynamics. Inversely, cognitive neuroscience could benefit from psychoanalysis by taking into account, when interpretating the scores, the relational dynamics and the personal history of the rater.

BACKGROUND: Validity studies of the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS) interview are modest in number given the international acceptance and extensive use of this instrument in epidemiological and treatment research. The results are somewhat mixed and limited, particularly for adolescent depression. AIMS: The objective of this study was to assess the convergent-divergent validity of the screen criteria and depression diagnoses (major depressive episode) generated with the diagnostic interview Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). METHODS: Participants were 86 consecutively admitted inpatients aged 12-17 years and their parents. Both convergent and divergent validity of the depression diagnoses were assessed against 11 standard self-report or parent-report rating scales, all of which had been translated, adapted and in most cases validated in Iceland. A total of 25 subscales were included in calculations. RESULTS: Convergent validity was confirmed, with adolescents who screened positive or met criteria for major depressive episode scoring higher than other patients did on scales assessing depressive symptoms. However, divergent validity was only partially supported in this highly comorbid inpatient sample. Severity based on number of diagnostic criteria met had a generally substantial correlation with the rating scales. CONCLUSIONS: This study provides a substantial additional amount of convergent-divergent validity data related to this extensively used diagnostic instrument.

AIMS: To estimate the prognostic value of injury severity, location of event, and demographic parameters, for symptoms of pediatric traumatic head injury (THI) 4 years later. METHODS: Data were collected prospectively from Reykjavik City Hospital on all patients age 0-19 years, diagnosed with THI (n = 408) during one year. Information was collected on patient demographics, location of traumatic event, cause of injury, injury severity, and ICD-9 diagnosis. Injury severity was estimated according to the Head Injury Severity Scale (HISS). Four years post-injury, a questionnaire on late symptoms attributed to the THI was sent. RESULTS: Symptoms reported were more common among patients with moderate/severe THI than among others (p < 0.001). The event location had prognostic value (p < 0.05). Overall, 72% of patients with moderate/severe motor vehicle-related THI reported symptoms. There was a curvilinear age effect (p < 0.05). Symptoms were least frequent in the youngest age group, 0-4 years, and most frequent in the age group 5-14 years. Gender and urban/rural residence were not significantly related to symptoms. CONCLUSIONS: Motor vehicle related moderate/severe THI resulted in a high rate of late symptoms. Location had a prognostic value. Patients with motor vehicle-related THI need special consideration regardless of injury severity.
RESUMEN
AIMS: To estimate differences in the incidence of recorded traumatic head injuries by gender, age, severity, and geographical area. METHODS: The study was prospective and nationwide. Data were collected from all hospitals, emergency units and healthcare centers in Iceland regarding all Icelandic children and adolescents 0-19 years old consecutively diagnosed with traumatic head injuries (N = 550) during a one-year period. RESULTS: Annual incidence of minimal, mild, moderate/severe, and fatal head injuries (ICD-9 850-854) was 6.41 per 1000, with 95% confidence interval (CI) 5.9, 7.0. Annual incidence of minimal head injuries (ICD-9 850) treated at emergency units was 4.65 (CI 4.2, 5.1) per 1000, mild head injuries admitted to hospital (ICD-9 850) was 1.50 (CI 1.3, 1.8) per 1000, and moderate/severe nonfatal injuries (ICD-9 851-854) was 0.21 (CI 0.1, 0.3) per 1000. Death rate was 0.05 (CI 0.0, 0.1) per 1000. Young children were at greater risk of sustaining minimal head injuries than older ones. Boys were at greater risk than girls were. In rural areas, incidence of recorded minimal head injuries was low. CONCLUSIONS: Use of nationwide estimate of the incidence of pediatric head injury shows important differences between urban and rural areas as well as between different age groups.
