Lack of efficacy of citalopram in children with autism spectrum disorders and high levels of repetitive behavior: citalopram ineffective in children with autism.

CONTEXT Selective serotonin reuptake inhibitors are widely prescribed for children with autism spectrum disorders. OBJECTIVES To determine the efficacy and safety of citalopram hydrobromide therapy for repetitive behavior in children with autism spectrum disorders. DESIGN National Institutes of Health-sponsored randomized controlled trial. SETTING Six academic centers, including Mount Sinai School of Medicine, North Shore-Long Island Jewish Health System, University of North Carolina at Chapel Hill, University of California at Los Angeles, Yale University, and Dartmouth Medical School. PARTICIPANTS One hundred forty-nine volunteers 5 to 17 years old (mean [SD] age, 9.4 [3.1] years) were randomized to receive citalopram (n = 73) or placebo (n = 76). Participants had autistic spectrum disorders, Asperger disorder, or pervasive developmental disorder, not otherwise specified; had illness severity ratings of at least moderate on the Clinical Global Impressions, Severity of Illness Scale; and scored at least moderate on compulsive behaviors measured with the Childrens Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders. INTERVENTIONS Twelve weeks of citalopram hydrobromide (10 mg/5 mL) or placebo. The mean (SD) maximum dosage of citalopram hydrobromide was 16.5 (6.5) mg/d by mouth (maximum, 20 mg/d). MAIN OUTCOME MEASURES Positive response was defined by a score of much improved or very much improved on the Clinical Global Impressions, Improvement subscale. An important secondary outcome was the score on the Childrens Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders. Adverse events were systematically elicited using the Safety Monitoring Uniform Report Form. RESULTS There was no significant difference in the rate of positive response on the Clinical Global Impressions, Improvement subscale between the citalopram-treated group (32.9%) and the placebo group (34.2%) (relative risk, 0.96; 95% confidence interval, 0.61-1.51; P > .99). There was no difference in score reduction on the Childrens Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders from baseline (mean [SD], -2.0 [3.4] points for the citalopram-treated group and -1.9 [2.5] points for the placebo group; P = .81). Citalopram use was significantly more likely to be associated with adverse events, particularly increased energy level, impulsiveness, decreased concentration, hyperactivity, stereotypy, diarrhea, insomnia, and dry skin or pruritus. CONCLUSION Results of this trial do not support the use of citalopram for the treatment of repetitive behavior in children and adolescents with autism spectrum disorders.

Medication and Parent Training in Children With Pervasive Developmental Disorders and Serious Behavior Problems: Results From a Randomized Clinical Trial

OBJECTIVE Many children with pervasive developmental disorders (PDDs) have serious, functionally impairing behavioral problems. We tested whether combined treatment (COMB) with risperidone and parent training (PT) in behavior management is superior to medication alone (MED) in improving severe behavioral problems in children with PDDs. METHOD This 24-week, three-site, randomized, parallel-groups clinical trial enrolled 124 children, aged 4 through 13 years, with PDDs, accompanied by frequent tantrums, self-injury, and aggression. The children were randomized 3:2 to COMB (n = 75) or MED (n = 49). The participants received risperidone monotherapy from 0.5 to 3.5 mg/day (with switch to aripiprazole if risperidone was ineffective). Parents in the COMB group (n = 75; 60.5%) received a mean of 10.9 PT sessions. The primary measure of compliance was the Home Situations Questionnaire (HSQ) score. RESULTS Primary: intent-to-treat random effects regression showed that COMB was superior to MED on HSQ (p = .006) [effect size at week 24 (d) = 0.34]. The HSQ score declined from 4.31 (± 1.67) to 1.23 (± 1.36) for COMB compared with 4.16 (± 1.47) to 1.68 (± 1.36) for MED. Secondary: groups did not differ on Clinical Global Impressions-Improvement scores at endpoint; compared with MED, COMB showed significant reductions on Aberrant Behavior Checklist Irritability (d = 0.48; p = .01), Stereotypic Behavior (d = 0.23; p = .04), and Hyperactivity/Noncompliance subscales (d = 0.55; p = .04). Final risperidone mean dose for MED was 2.26 mg/day (0.071 mg/kg), compared with 1.98 mg/day for COMB (0.066 mg/kg) (p = .04). CONCLUSIONS Medication plus PT resulted in greater reduction of serious maladaptive behavior than MED in children with PDDs, with a lower risperidone dose.

Cognitive-behavioral therapy for suicide prevention (CBT-SP): treatment model, feasibility, and acceptability.

OBJECTIVE To describe the elements of a manual-based cognitive-behavioral therapy for suicide prevention (CBT-SP) and to report its feasibility in preventing the recurrence of suicidal behavior in adolescents who have recently attempted suicide. METHOD The CBT-SP was developed using a risk reduction and relapse prevention approach and theoretically grounded in principles of cognitive-behavioral therapy, dialectical behavioral therapy, and targeted therapies for suicidal youths with depression. The CBT-SP consists of acute and continuation phases, each lasting about 12 sessions, and includes a chain analysis of the suicidal event, safety plan development, skill building, psychoeducation, family intervention, and relapse prevention. RESULTS The CBT-SP was administered to 110 recent suicide attempters with depression aged 13 to 19 years (mean 15.8 years, SD 1.6) across five academic sites. Twelve or more sessions were completed by 72.4% of the sample. CONCLUSIONS A specific intervention for adolescents at high risk for repeated suicide attempts has been developed and manual based, and further testing of its efficacy seems feasible.

Additive Effects of Psychostimulants, Parent Training, and Self-Control Therapy with ADHD Children

Utilizing a double-blind, placebo design, the effects of a high (0.8 mg/kg) and a low (0.4 mg/kg) dose of methylphenidate alone and in combination with behavioral parent training plus child self-control instruction were evaluated with 96 attention deficit hyperactivity disorder children. No evidence of the superiority of the combined conditions relative to medication alone was found. Some limited support was found for the hypothesis that the effects of a high dose of psychostimulant medication could be achieved by combining the low dose with a behavioral intervention. The importance of the latter finding is highlighted by the fact that both the benefits and untoward effects of the psychostimulants appear to increase with the dose.

The Treatment of Adolescent Suicide Attempters Study (TASA): Predictors of Suicidal Events in an Open Treatment Trial

OBJECTIVE To identify the predictors of suicidal events and attempts in adolescent suicide attempters with depression treated in an open treatment trial. METHOD Adolescents who had made a recent suicide attempt and had unipolar depression (n =124) were either randomized (n = 22) or given a choice (n = 102) among three conditions. Two participants withdrew before treatment assignment. The remaining 124 youths received a specialized psychotherapy for suicide attempting adolescents (n = 17), a medication algorithm (n = 14), or the combination (n = 93). The participants were followed up 6 months after intake with respect to rate, timing, and predictors of a suicidal event (attempt or acute suicidal ideation necessitating emergency referral). RESULTS The morbid risks of suicidal events and attempts on 6-month follow-up were 0.19 and 0.12, respectively, with a median time to event of 44 days. Higher self-rated depression, suicidal ideation, family income, greater number of previous suicide attempts, lower maximum lethality of previous attempt, history of sexual abuse, and lower family cohesion predicted the occurrence, and earlier time to event, with similar findings for the outcome of attempts. A slower decline in suicidal ideation was associated with the occurrence of a suicidal event. CONCLUSIONS In this open trial, the 6-month morbid risks for suicidal events and for reattempts were lower than those in other comparable samples, suggesting that this intervention should be studied further. Important treatment targets include suicidal ideation, family cohesion, and sequelae of previous abuse. Because 40% of events occurred with 4 weeks of intake, an emphasis on safety planning and increased therapeutic contact early in treatment may be warranted.

Cognitive Training in Mental Disorders: Update and Future Directions

OBJECTIVE This article reviews the conceptual basis, definitions, and evolution of cognitive training approaches for the treatment of mental disorders. METHOD The authors review the current state of the knowledge on cognitive training in psychiatric illnesses, and its neural and behavioral targets, and summarize the factors that appear to relate to a successful response, including learner characteristics that influence clinical outcome. They also discuss methodological issues relevant to the development and testing of cognitive training approaches, with the goal of creating maximally efficient and effective approaches to training. Finally, they identify gaps in existing knowledge and outline key research directions for the future. RESULTS While much of the early research has been conducted in schizophrenia, cognitive training has more recently been applied to a widening range of neuropsychiatric illnesses, including attention deficit hyperactivity disorder, mood disorders, and substance use disorders. Cognitive training harnesses the inherent neuroplastic capacities of the brain, targeting neural system function across psychiatric disorders, thus improving the cognitive processes that play a role in emotion regulation, clinical symptoms, and adaptive community functioning. CONCLUSIONS Cognitive training offers considerable promise, especially given the limited efficacy of pharmacological interventions in ameliorating cognitive deficits. However, more research is needed to understand the mechanisms underlying cognitive training, predictors of response, generalization and real-world applicability, and approaches to dissemination in practice settings.

Depressive Symptoms and Clinical Status During the Treatment of Adolescent Suicide Attempters (TASA) Study

OBJECTIVE To examine the course of depression during the treatment of adolescents with depression who had recently attempted suicide. METHOD Adolescents (N = 124), ages 12 to 18 years, with a 90-day history of suicide attempt, a current diagnosis of depressive disorder (96.0% had major depressive disorder), and a Childrens Depression Rating Scale-Revised (CDRS-R) score of 36 or higher, entered a 6-month treatment with antidepressant medication, cognitive-behavioral therapy focused on suicide prevention, or their combination (Comb), at five academic sites. Treatment assignment could be either random or chosen by study participants. Intent-to-treat, mixed effects regression models of depression and other relevant ratings were estimated. Improvement and remission rates were computed with the last observation carried forward. RESULTS Most patients (n = 104 or 84%) chose treatment assignment, and overall, three fourths (n = 93) received Comb. In Comb, CDRS-R declined from a baseline adjusted mean of 49.6 (SD 12.3) to 38.3 (8.0) at week 12 and to 27.0 (10.1) at week 24 (p < .0001), with a Clinical Global Impression -defined improvement rate of 58.0% at week 12 and 72.2% at week 24 and a remission (CDRS-R ≤ 28) rate of 32.5% at week 12 and 50.0% at week 24. The CDRS-R and the Scale for Suicidal Ideation scores were correlated at baseline (r = 0.43, p < .0001) and declined in parallel. CONCLUSIONS When vigorously treated with a combination of medication and psychotherapy, adolescents with depression who have recently attempted suicide show rates of improvement and remission of depression that seem comparable to those observed in nonsuicidal adolescents with depression.

Developmental Disabilities Modification of the Children’s Global Assessment Scale

BACKGROUND Interventions for pervasive developmental disorders (PDD) aim to alleviate symptoms and improve functioning. To measure global functioning in treatment studies, the Childrens Global Assessment Scale was modified and psychometric properties of the revised version (DD-CGAS) were assessed in children with PDD. METHODS Developmental disabilities-relevant descriptors were developed for the DD-CGAS, and administration procedures were established to enhance rater consistency. Ratings of clinical case vignettes were used to assess inter-rater reliability and temporal stability. Validity was assessed by correlating the DD-CGAS with measures of functioning and symptoms in 83 youngsters with PDD. Sensitivity to change was assessed by comparing change from baseline to post-treatment with change on the Aberrant Behavior Checklist-Irritability and Clinical Global Impressions-Improvement subscale scores in a subset of 14 children. RESULTS Inter-rater reliability (intraclass correlation coefficient [ICC] = .79) and temporal stability (average ICC = .86) were excellent. The DD-CGAS scores correlated with measures of functioning and symptoms with moderate to large effect sizes. Changes on the DD-CGAS correlated with changes on the Aberrant Behavior Checklist-I (r = -.71) and Global Impressions Scale-I (r = -.52). The pre-post DD-CGAS change had an effect size of .72. CONCLUSIONS The DD-CGAS is a reliable instrument with apparent convergent validity for measuring global functioning of children with PDD in treatment studies.

Design and Subject Characteristics in the Federally-Funded Citalopram Trial in Children with Pervasive Developmental Disorders

The Studies to Advance Autism Research and Treatment Network conducted a randomized trial with citalopram in children with Pervasive developmental disorders (PDDs). We present the rationale, design and sample characteristics of the citalopram trial. Subjects (128 boys, 21 girls) had a mean age of 9.3 (±3.12) years; 132 (88.6%) were diagnosed with autistic disorder (4.7% with Asperger’s Disorder; 6.7% with PDD-not otherwise specified). Less than half of the subjects were intellectually disabled; 117 (78.5%) were rated Moderate or Marked on the Clinical Global Impression for Severity. Study measures were similar to previous Research Units on Pediatric Psychopharmacology trials. Subjects in this trial were slightly older and more likely to have complaints of repetitive behavior than participants in RUPP trials.

From bench to bedside: translating new research from genetics and neuroimaging into treatment development for early-onset schizophrenia

Objective: Children and adolescents with schizophrenia share a similar pattern of phenomenological, genetic and cognitive abnormalities to adults with schizophrenia. However, an early‐onset of schizophrenia (EOS) (prior to 18 years of age) is associated with a higher frequency of risk indicators associated with schizophrenia (e.g. developmental delays and familial spectrum disorders) and a worse long‐term outcome. This overview examines recent research on the neurobiological alterations, possible causes, developmental trajectory and treatment of EOS and attempts to identify gaps in the field.
