Short- and Long-Term Effects of Parent Training for Preschool Children With or at Risk of ADHD: A Systematic Review and Meta-Analysis

Attention-deficit hyperactivity disorder

Attention-deficit hyperactivity disorder (ADHD), like other psychiatric disorders, represents an evolving construct that has been refined and developed over the past several decades in response to research into its clinical nature and structure. The clinical presentation and course of the disorder have been extensively characterised. Efficacious medication-based treatments are available and widely used, often alongside complementary psychosocial approaches. However, their effectiveness has been questioned because they might not address the broader clinical needs of many individuals with ADHD, especially over the longer term. Non-pharmacological approaches to treatment have proven less effective than previously thought, whereas scientific and clinical studies are starting to fundamentally challenge current conceptions of the causes of ADHD in ways that might have the potential to alter clinical approaches in the future. In view of this, we first provide an account of the diagnosis, epidemiology, and treatment of ADHD from the perspective of both the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders and the eleventh edition of the International Classification of Diseases. Second, we review the progress in our understanding of the causes and pathophysiology of ADHD on the basis of science over the past decade or so. Finally, using these discoveries, we explore some of the key challenges to both the current models and the treatment of ADHD, and the ways in which these findings can promote new perspectives.

Are parental changes related to improvements in preschool children's disruptive behaviours?

OBJECTIVE

To investigate whether changes in parenting after behavioural parent training in routine clinical care are associated with improvements in preschool children's disruptive behaviours.

METHOD

We evaluated changes after parent training in maternal and paternal self-reports of parental discipline practices parenting sense of competence, and parents' ratings of child disruptive behaviours in parents of 63 children, with a one group pretest-posttest design. We also compared parenting parameters in this clinical sample with a nonclinical sample (n = 121).

RESULTS

Mothers' self-reports of parental discipline practices and parenting sense of competence significantly improved after behavioural parent training. Less over-reactivity in both mothers and fathers was associated with fewer disruptive behaviours in children. After parent training, mothers' ratings of their discipline techniques did not differ anymore from those in the nonclinical sample.

CONCLUSION

Positive changes in parental discipline practices, particularly less over-reactive parental behaviours, were related to a decrease of disruptive child behaviours.

Parents in Control: Parental perceptions of problem behaviors before and after attending an ADHD-specific parent-training program

PROBLEM

There is scant evidence to support the efficacy of attention deficit hyperactivity disorder (ADHD)-specific parent-training programs in the treatment of preadolescent children with ADHD. This study explores the effectiveness of the Parents in Control (PINC) parent-training program, designed specifically for children with ADHD.

METHODS

In this pragmatic uncontrolled pre-poststudy parents of preadolescent children with a diagnosis of ADHD were invited to attend the 6-week PINC course. Fifty-seven parent-report pre/postprogram questionnaires were completed.

FINDINGS

Parental ratings of the intensity and frequency of problem behaviors after completing PINC showed a significant reduction (p < .001) with a moderate effect size (0.6-0.7).

CONCLUSIONS

Our findings demonstrate the efficacy of PINC in reducing the parental perception of problem behaviors and support a need for further rigorous randomised controlled trial (RCT) evaluation of this ADHD-specific intervention.

ADHD in children and youth: Part 2-Treatment

Attention-deficit hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder. Three position statements have been developed by the Canadian Paediatric Society, following systematic literature reviews. Statement objectives are to: 1) Summarize the current clinical evidence regarding ADHD,2) Establish a standard for ADHD care, and3) Assist Canadian clinicians in making well-informed, evidence-based decisions to enhance care of children and youth with this condition. Specific topics reviewed in Part 2, which focuses on treatment, include: evidence and context for a range of clinical approaches, combining behavioural and pharmacological interventions to address impairment more effectively, the role of parent and teacher (or other caregiver) training, the use of stimulant and nonstimulant medications, with effects and risks, and dosing and monitoring protocols. Treatment recommendations are based on current guidelines, evidence from the literature, and expert consensus.

Meta-meta-analysis on the effectiveness of parent-based interventions for the treatment of child externalizing behavior problems

Objective

The aim of this study is to perform the first meta-meta-analysis on the effectiveness of parent-based interventions for children with externalizing behavior problems. Even though parent-based interventions are considered as effective treatments the effects reported in meta-analyses are heterogeneous and the implementation in clinical practice is suboptimal. Recapitulative valid effect predictions are required to close the still existing gap between research findings and clinical practice. The meta-meta-analytic results on changes in child behavior shall result in a clear signal for clinical practice.

Methods

This meta-meta-analysis encompasses 26 meta-analyses identified via search in electronic databases (PsycINFO, Medline, PubMed). Meta-analyses had to report effects of parent-based interventions on child behavior and focus on children under the age of 13 years with externalizing behavior problems in a clinical setting. Analyses were based on random-effects models. To combine results, the effect estimates of the meta-analyses were transformed to SMD and weighted to correct for primary study overlap. The meta-meta-analysis is registered on PROSPERO, registration number CRD42016036486 and was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement (PRISMA).

Results

The results indicate a significant moderate overall effect for child behavior (SMD = 0.46) as well as for parent reports (SMD = 0.51) and observational data (SMD = 0.62). Further analyses focusing on child externalizing behavior yielded significant and moderate effects (SMD = 0.45). All effects remained stable to follow-up. Considerable heterogeneity was observed within results.

Conclusion

Parent-based interventions are shown to be effective in improving behavior in children with externalizing behavior problems, as assessed using parent reports and observational measures. The present results should encourage health care providers to apply evidence-based parent-based interventions.

Parenting practices of Singaporean mothers of children with ADHD

Objectives:

We wanted to determine: (1) whether ADHD symptoms were more common in mothers of children with ADHD; (2) whether mothers of children with ADHD differed in their parenting strategies; and (3) whether there was a difference in care-giving arrangements for children with ADHD and without ADHD. This was done by comparing mothers of children with ADHD with mothers of children without ADHD in Singapore.

Methods:

Mothers of children with ADHD ( n=46) and mothers of children without ADHD ( n=45) completed the Conners’ Parent Rating Scale-Revised, the Conners’ Adult ADHD Rating Scale-Self Report and the Alabama Parenting Questionnaire.

Results:

Mothers of children with ADHD did not report higher levels of current ADHD symptoms compared with the control group. However, they did use less adaptive parenting strategies. There were also no differences in the reported behaviours of children cared for by a paid worker and those cared for by mothers.

Conclusions:

Data support the Singapore Clinical Guidelines recommendations for the promotion of parenting skills, and referral to parenting programmes for parents of children with ADHD. The promotion of parenting skills and referral to parenting programmes for mothers of children with ADHD might include the option of electronic forms of programme delivery. The model of using paid help in the home, which is commonplace in Singapore, does not seem to disadvantage children with ADHD.

Preschool children's response to behavioural parent training and parental predictors of outcome in routine clinical care

OBJECTIVE

To investigate the effectiveness of behavioral parent training (BPT) for preschool children with disruptive behaviours and to explore parental predictors of response.

METHODS

Parents of 68 preschool children, aged between 2.7 and 5.9 years, participated in BPT. We evaluated the changes in children's behaviour after BPT with a one group pretest-posttest design, using a waiting period for a double pretest. Outcome was based on parents' reports of the intensity and number of behaviour problems on the Eyberg Child Behavior Inventory. Predictor variables included parents' attention-deficit/hyperactivity disorder symptoms, antisocial behaviours, and alcohol use, and maternal parenting self-efficacy and disciplining.

RESULTS

Mother-reported child behaviour problems did not change in the waiting period but improved significantly after BPT (d = 0.63). High levels of alcohol use by fathers and low levels of maternal ineffective disciplining were each associated with somewhat worse outcome.

CONCLUSIONS

BPT under routine care conditions clearly improves disruptive behaviours in preschool children. Mothers who consider themselves as inadequate in disciplining and mothers whose partners do not consume high levels of alcohol report the largest improvements.

Face-to-Face Versus Online Behavioral Parent Training for Young Children at Risk for ADHD: Treatment Engagement and Outcomes

Attention deficit/hyperactivity disorder (ADHD) is associated with significant challenges in child functioning. Although behavioral parent training (BPT) can reduce ADHD symptoms, factors associated with traditional face-to-face (F2F) delivery results in only about half of families receiving BPT. The purpose of this pilot randomized controlled trial was to examine parent engagement and program acceptability of F2F and online BPT, as well as the efficacy of both formats relative to a waitlist control (WLC) group. Participants were 47 families with preschool children (30 boys, 17 girls) who were between the ages of 3 years 0 months (3;0) and 5 years 11 months (5;11) old who were identified at risk for ADHD. Children were randomly assigned to F2F or online BPT or to WLC; parents in the two treatment conditions received 10 sessions of BPT. Assessment data for all groups were collected at pre-, mid-, and posttreatment. Both intervention formats resulted in high attendance (M = 80%) and significantly improved parent knowledge of interventions, treatment implementation fidelity, and child behavior (reduced restlessness and impulsivity, improved self-control, affect, and mood) compared with WLC. However, parents in the F2F group reported significantly higher acceptability ratings than parents in the online group. Findings indicate a streamlined BPT delivered online or F2F results in high levels of engagement, acceptability, as well as parent treatment knowledge and fidelity. Online BPT is associated with similar efficacious outcomes with F2F BPT, suggesting the need for further research to determine variables that predict greater acceptability for and adoption of this format.
