Interview data were coded according to the Consolidated Framework for Implementation Research (CFIR) and examined for patterns of similarity or divergence across data sources, respondents or other relevant characteristics.Setting Child and adolescent outpatient mental health service, Nova Scotia, Canada.Participants IWK Health clinicians and staff who had participated in virtual mental healthcare following its implementation in March 2020 and clients (aged 12–18 years) and caregivers of clients (aged 3–18 years) who had received treatment from an IWK outpatient clinic between 1 April 2020 and 31 March 2022 (n=1300). Participants (n=48) in semi-structured interviews included nine clients aged 13–18 years (mean 15.7 years), 10 caregivers of clients aged 5–17 years (mean 12.7 years), eight Community Mental Health and Addictions booking and registration or administrative staff and 21 clinicians.Results During peak pandemic activity, upwards of 90% of visits (first or return) were conducted virtually. Between waves, return appointments were more likely to be virtual than first appointments. Interview participants (n=48) reported facilitators and barriers to virtual care within the CFIR domains of ‘outer setting’ (eg, external policies, client needs and resources), ‘inner setting’ (eg, communications within the service), ‘individual characteristics’ (eg, personal attributes, knowledge and beliefs about virtual care) and ‘intervention characteristics’ (eg, relative advantage of virtual or in-person care).Conclusions Shared decision-making regarding treatment modality (virtual vs in-person) requires consideration of client, caregiver, clinician, appointment, health system and public health factors across episodes of care to ensure accessible, safe and high-quality mental healthcare.

Background: Infant mental health has emerged as a unique area of practice and research distinguished from child and youth sub-specialties by its advocacy for a relational practice framework with an emphasis on parents/caregivers being integral to assessment, treatment, and prevention initiatives. A diverse array of initiatives offered across a broad spectrum of delivery methods is available to clinicians. However, to date, a large-scale mapping of the research evidence regarding these interventions has yet to be completed to help inform clinician's decisions regarding the best approaches for their clients. To address this knowledge gap, this study aimed to report on the landscape of research pertaining to mental health interventions for infants and preschoolers (0-5 years), and their families at risk for socio-emotional difficulties and negative developmental outcomes., Method: A scoping review methodology was used to conduct a large-scale mapping of the intervention research pertaining to infants and preschoolers (0-5) at risk for socio-emotional difficulties. We searched MEDLINE, PsycINFO, EMBASE, Web of Science, The Cochrane Library, CINAHL, LILACS, ProQuest Nursing & Allied Health Source, World Cat, and ClinicalTrials.gov , from inception to December 31, 2012. We extracted information regarding publication date, geographical location, study design, level of risk, population, key intervention mechanism, and outcome measures., Results: We identified 533 potential studies from 1233 title and abstracts after the first round of screening. Full text article review in the second round of screening resulted in a total of 162 included articles for the final analysis. Results indicated that over 50% of interventions evaluated were randomized controlled trials conducted in Westernized countries. Most studies could be subdivided by level of risk within a preventative public health framework including universal, selected, indicated, and direct treatment for children formally diagnosed with a mental disorder. Risk factors experienced by children and their families were heterogeneously defined and numerous outcome measures across included studies. The results of this study are limited to the last search date of 2012., Conclusions: Key intervention mechanisms spanned a range of approaches including parenting groups, dyadic, in-home, cognitive-behavioral therapy, and day care-based interventions. The findings are discussed in terms of implications for broad trends and gaps in research and policy for this population.

Parents referred to child welfare services for child maltreatment often struggle against chronic risk factors including violence, substance abuse, mental health concerns, and poverty, which impinge upon their ability to be sensitive caregivers. The first line of intervention within the child welfare context is to modify parenting behavior. This scoping review comprehensively surveyed all available literature to map the extent and range of research activity around the types of interventions available within a child welfare context to parents of infants and toddlers (0-5 years of age), to identify the facilitators and/or barriers to the uptake of interventions, and to check that interventions match the risk factors faced by parents. This scoping review engaged in stringent screening of studies based upon inclusion/exclusion criteria. Sixty-five articles involving forty-two interventions met inclusion criteria. Interventions generally aimed to improve parenting practices, the relationship between parent and child, and/or attachment security, along with reducing child abuse and/or neglect. A notable finding of this scoping review is that at present, interventions for parents of children ages 0-5 involved with the child welfare system are most frequently measured via case study and quasi-experimental designs, with randomized control trials making up 26.2% of included study designs., (Copyright © 2017 Elsevier Ltd.

Background: Current early childhood systems of care are not geared to respond to the complex needs of preschoolers at risk for mental health problems in a timely, coordinated, multidisciplinary, and comprehensive fashion. Evidence-informed policy represents an opportunity for implementing prevention, promotion, and early intervention at the population or at-risk level. Exposure to risk factors as well as the presence of clinical disorders can derail the developmental trajectories of preschoolers, and problems may persist if left untreated. One way to address these multiple research-to-policy gaps are systematic reviews sensitive to context and knowledge user needs, such as the realist review. The realist review is an iterative process between research teams and knowledge users to build mid-level program theories in order to understand which interventions work best for whom and under what context., Methods/design: The realist review employs five 'iterative' steps: (1) clarify scope, (2) search for evidence, (3) appraise primary studies and extract data, (4) synthesize the evidence, and (5) disseminate, implement, and evaluate evidence, to answer two research questions: What interventions improve mental health outcomes for preschoolers at risk for socio-emotional difficulties and under what circumstances do they work? and what are the best models of care for integrating mental health interventions within pre-existing early childhood education (ECE) services for at-risk children? Knowledge users and researchers will work together through each stage of the review starting with refining the questions through to decisions regarding program theory building, data extraction, analysis, and design of a policy dissemination plan. The initial questions will guide preliminary literature reviews, but subsequent more focused searches will be informed by knowledge users familiar with local needs and further building of explanatory program theories., Discussion: Policy makers want to know what works best for whom, but are faced with a wide and disparate intervention literature for at-risk children. Applying evidence-based standards is a good start, but the chain of implementation between research results and how to match interventions sensitive to local context are ongoing challenges., Trial Registration: Prospero registration number: CRD42014007301.

The current study examines the role of callous/unemotional (CU) traits in response to treatment among children with conduct problems (CP) and attention-deficit/hyperactivity disorder (ADHD). Fifty-four children with CP/ADHD and 16 controls (age = 9.48, SD = 1.58) took part in a summer treatment and research program. Simple correlations showed that CU and CP were associated with a number of treatment outcome measures. When examined together in regression analyses, CU and CP were uniquely associated with three treatment outcomes each (CU-improvement in social skills and problem solving, negative behaviors in time-out; CP-time-outs per day, peer ratings, peer dislike). The implications for these findings with regard to treatment response in children with CP/ADHD with and without CU traits are explored.

This study examined whether response to behavior modification with and without methylphenidate differed for children with attention-deficit/hyperactivity disorder (ADHD) and conduct problems (CP) depending on the presence of callous/unemotional (CU) traits. Participants were 37 children ages 7 to 12, including 19 with ADHD/CP-only and 18 with ADHD/CP-CU, referred to a university-based summer treatment program. Results showed that ADHD/CP-CU children had worse behavior in the behavior-therapy-only (BT-only) condition, especially on measures of CP, noncompliance, and rule violations, but these differences largely disappeared when medication was added to BT. Children with ADHD/CP-CU were also less likely to be normalized by treatment than were children with ADHD/CP-only. These findings, though tentative, suggest that children with ADHD/CP-CU may not show a sufficient positive response to BT alone and that the combination of medication and BT may be especially important for them.

This study examined the association between social problem solving, conduct problems (CP), and callous-unemotional (CU) traits in elementary age children. Participants were 53 children (40 boys and 13 girls) aged 7-12 years. Social problem solving was evaluated using the Social Problem Solving Test-Revised, which requires children to produce solutions to eight hypothetical social problems, including five problems involving acquiring a desired object and three problems gaining access to a peer. Regression analyses showed that greater frequency of CP symptoms was associated with producing less flexible, relevant, and prosocial solutions and more overtly aggressive solutions. However, this pattern was present only when CU traits were low. Results add to a growing body of literature demonstrating that CU traits are an important moderator of CP in children.

Objective: The glutamatergic prefrontal-striatal pathway has been implicated previously in the neurobiology of attention-deficit/hyperactivity disorder (ADHD). We used short echo proton magnetic resonance spectroscopy (1H-MRS) to examine glutamate in the prefrontal cortex, left striatum, and, as a control area, the occipital lobe., Method: Thirteen treatment-naïve ADHD children and 10 healthy comparison subjects participated. All were males between the ages of 6 to 11 years of age. Twelve ADHD subjects were scanned after 8 weeks of treatment., Results: Striatal glutamate, glutamate/glutamine (Glx) and creatine concentrations were greater in the ADHD subjects at baseline as compared to controls. Only striatal creatine, not glutamate or Glx, was reduced after stimulant treatment in the ADHD patients. No significant differences between groups were noted in the remainder of the striatal metabolites or any of the occipital lobe or prefrontal cortex metabolites., Conclusions: These findings provide initial evidence of a striatal creatine/glutamatergic dysregulation in ADHD.

Objective: To explore whether developmental status of neurotransmitter systems may affect response to antidepressant treatment. This study investigated whether younger animals, compared with mature animals, showed the same neuroendocrine response to challenge drug probes when pretreated with a serotonergic or noradrenergic antidepressant., Method: Prepubertal, pubertal, and adult rats were pretreated with low- or high-dose sertraline or desipramine for 14 days. Animals were then challenged with a noradrenergic probe (clonidine for desipramine-treated animals) or a serotonergic probe (fenfluramine for sertraline-treated animals). The neurohormonal response of growth hormone to the clonidine challenge and prolactin to the fenfluramine challenge was then measured., Results: In animals challenged with fenfluramine, the postpubertal control group showed a significantly higher prolactin response to fenfluramine than postpubertal animals pretreated with low- or high-dose sertraline. No differences were found in the pubertal or prepubertal group. In animals challenged with clonidine, there was a significant age by treatment interaction effect for the prepubertal group pretreated with high doses of desipramine (less growth hormone secretion) but not for the peri- or postpubertal groups., Conclusions: These data indicate neurodevelopmental factors may play a role in the functional physiology of neurotransmitter systems, which in turn may affect response to psychotropics.

A review was undertaken of studies evaluating the efficacy and tolerability of antipsychotic medications for the management of psychosis in children and adolescents. All identified published and unpublished studies from 1996 onward were included for review. The search located one randomized control trial, seven open-label trials, six retrospective chart reviews, and nine case reports. The studies assessed the use of haloperidol, clozapine, risperidone, olanzapine, and quetiapine in the management of psychosis in children and adolescents. Most studies reported reasonable treatment response; however, extrapyramidal side effects, sedation, and weight gain are concerning. This points to the need for appropriate baseline assessments prior to initiating treatment with these agents. Particular attention should be given to assessment of the extrapyramidal system as well as to baseline weight, lipid profile, and blood glucose. Further study is needed to refine the use of antipsychotic medications in children and adolescents in order to minimize adverse effects while conferring an optimum therapeutic response. The importance of instituting effective early treatment in youth with psychoses is an important goal that may serve to lessen the long-term morbidity of the illness.

This article is a practical review of the current psychopharmacological agents used in the treatment of child and adolescent psychiatric disorders. Psychostimulants such as methylphenidate, dexamphetamine and pemoline are effective in the control of symptoms associated with attention deficit hyperactivity disorder. The controlled release preparations and the adjunctive use of clonidine are helpful to extend stimulant effects and control adverse effects. Tricyclic antidepressants are helpful in individual cases of child and adolescent depression, but adverse effects may limit their use. Clomipramine has been found to be effective for childhood obsessive-compulsive disorder. Selective serotonin (5-HT) reuptake inhibitors (SSRIs) appear to be safer for depression and are also useful in obsessive-compulsive disorder. Buspirone is effective for the treatment of anxiety disorders in children. Newer atypical antipsychotics such as risperidone may have less limiting adverse effects than older antipsychotics in the treatment of psychosis and severe behaviour disorders, but the physician must be vigilant for the emergence of tardive dyskinesia. Drug treatment in children and adolescents must take into account the child's environmental influences and be part of an overall treatment plan where individual, familial and cultural issues are addressed.

Objective: To demonstrate that Itard was one of the first clinicians to describe autism (which Itard named "intellectual mutism") and effectively separate these cases from mental retardation. Known for his attempts at rehabilitation of the Wild Boy of Aveyron, Itard wrote a largely unacknowledged paper in 1828 on the different causes of "intellectual mutism," the result of 28 years of observations at the Institut des Sourd-Muets in Paris., Method: Itard emphasized a complete examination of the child's faculties including attention, memory, and imitative capacity. He also described the behavior of these children as unsocialized, with poor peer relationships, superficial contact with adults in order to satisfy their own needs, and difficulties in language, especially with pronouns., Results: He then described his various diagnostic and treatment approaches to determine whether the child can regain language and is educable. His description of the key features of intellectual mutism is compared to Kanner's classic description of autism., Conclusion: Itard rejected the overly inclusive diagnosis of "idiocy" and offered a way to distinguish children with mental retardation from those with pervasive developmental disorders, described key clinical features, and offered an assessment and treatment of these cases, all before 1830. His contribution should be recognized in textbooks of child psychiatry and developmental disorders.

Objective: To compare the physiological responses of abused children to different stimuli with responses of children in a reference group and to correlate the physiological responses with intellectual and personality functioning., Method: Abused children were compared with a reference group on two batteries of tests that were administered on separate days. In one session, children were shown slides with emotional or cognitive content while heart rate, pulse height, skin conductance, electromyography, and skin temperature were measured. In the other session, intellectual and personality functioning was measured using the WISC-R, Quick Neurological Screening Test, and the Junior Eysenck personality inventory., Results: Abused children had smaller changes in pulse height in the first two stimulus conditions presented ("No Signal" and "Math"), but their electrodermal responses were lower throughout all stimulus conditions. Abused children also had higher introversion and lower Verbal and Full Scale IQ scores. Verbal and Full Scale IQ scores were inversely related to the severity of abuse that had been experienced. When these variables were used in a discriminant function analysis, children were assigned to the correct group 86% of the time., Conclusion: These findings support a model that describes the effects of abuse as delaying cognitive development and inhibiting physiological responsiveness to the environment.

1. Although the topic of the treatment of child abusers does not evoke much sympathy in the public or the mental health profession, the solution to this problem does not lie in hoping that all abusers should commit suicide--or that suicide is a deserved outcome for the abuser. 2. Our first priority is and should remain the child's safety; however, in too many cases the abuser-perpetrator is inextricably linked to the child, and whatever happens to the abuser may have consequences for the child. 3. It is hoped that the skewed punitive view of the abuser will change as we better understand the dynamics among violence, depression, and child abuse in our society. We could then offer the victim and perpetrator better treatment and improve our preventive strategies.

1. Although the management of sexually abused children is not new, a comprehensive approach is often lacking, especially as it pertains to dealing with sexually acting-out children. 2. In addition to the usual social work measures of child protection, a program of developmentally and psychoeducationally based interventions supplemented by behavioral techniques were found to be most effective. 3. Acting-out children often provoke reactions of rage, betrayal, and impotence among the staff. Discussions of interventions must take into account the staff's own philosophy about how sexuality should be taught to these children. 4. The treatment team leader must decide whether the sexual acting-out among children is due to active solicitation from sexually abused children, delinquent acting-out, or age-appropriate exploration.
