Families Who Benefit and Families Who Do Not: Integrating Person- and Variable-Centered Analyses of Parenting Intervention Responses

Individual Participant Data Meta-Analysis: Individual Differences in Mediators of Parenting Program Effects on Disruptive Behavior

OBJECTIVE

Although parenting programs are the most widely used approach to reduce disruptive behavior in children, there is a notable lack of understanding of the exact changes in parenting that underlie their effects. Challenges include the frequent use of composite measures of parenting behavior and insufficient power to detect mediation effects and individual differences in these in individual trials.

METHOD

Individual participant data from 14 European randomized controlled trials of social learning-based parenting programs were pooled to examine which specific parenting behaviors best explain program effects. Participants included 3,252 families with children ages 1 to 13 years. Parental use of praise, tangible rewards, physical discipline, harsh verbal discipline, and not following through on discipline were included as putative mediators. Additionally, the study explored whether subgroups of families showing different mediational pathways exist.

RESULTS

Changes in parenting partially mediated program effects, with all included parenting behaviors except parental use of praise serving as unique mediators. Less harsh verbal discipline and increased following through on discipline were the strongest mediators. The study identified 3 subgroups with distinct responses to parenting programs. Most families benefited, partly through increased following through on discipline; families with the least or most difficulties were more likely to benefit less or not at all.

CONCLUSION

These findings offer insight into the specific parenting behavior changes key to reducing disruptive child behavior, while highlighting the need for innovative research methodologies to gain a deeper understanding of individual differences in parenting program benefits and mechanisms.

PLAIN LANGUAGE SUMMARY

Parenting programs are the most widely used strategy to reduce children's disruptive behavior. In this analysis of individual data of 3,252 families that participated in 14 European randomized controlled trials, the authors examined which specific changes in parenting behaviors best explain the effects of parenting programs on children's behavior, and whether these changes might differ across different types of families. The authors found that changes in parenting behavior partially explained program effects on disruptive behavior. Reduced harsh verbal discipline and increased following through on discipline seemed the most important parenting behaviors. While most families benefited from parenting programs, those facing the most or the least difficulties benefited less.

Identifying patterns of multidimensional self-compassion in Chinese young adults: implications for longitudinal mental health outcomes during the pandemic

BACKGROUND

Self-compassion (SC), reflecting self-attitude and self-connectedness, has proven to be a modifiable factor in promoting mental health outcomes. Increasingly, SC is recognized as a multidimensional construct consisting of six dimensions, rather than a single dimension.

OBJECTIVES

First, this study adopted a person-centered approach to explore profiles of SC dimensions in Chinese young adults. Second, the study examined the predictive effects of SC profiles on mental health outcomes.

METHODS

In February 2020, young adults (N = 1164) were invited to complete the 26-item Neff's Self-Compassion Scale online. Three months later, the same subjects (N = 1099) reported their levels of depressive symptoms, posttraumatic stress disorder (PTSD) symptoms, and posttraumatic growth (PTG).

RESULTS

After controlling for retrospective ACEs, four classes best characterized the profiles: self-compassionate (26.7%, N = 294), self-uncompassionate (12.3%, N = 135), average (55.9%, N = 614), and detached groups (5.1%, N = 56). Young adults in the self-compassionate group adjusted the best (with the highest level of PTG and the lowest levels of depressive and PTSD symptoms). Adults in the self-uncompassionate group demonstrated the poorest mental health outcomes (with the lowest level of PTG and the highest levels of depressive and PTSD symptoms). Young adults in the average group obtained more PTG than adults in the detached group (p < .01), but did not differ significantly in depressive and PTSD symptoms (p > .05).

CONCLUSION

The compassionate profile is the most adaptable for young adults among all groups. This study highlights the limitations of representing the relative balance of SC with a composite score.

Predictors and Moderators Two Treatments of Oppositional Defiant Disorder in Children

OBJECTIVE

The aim of this study was to examine predictors and moderators of behavioral improvement in children with Oppositional Defiant Disorder (ODD) following treatment with Parent Management Training (PMT) and Collaborative and Proactive Solutions (CPS). Initial problem severity, inconsistent discipline, parental attributions of child misbehavior, and child lagging cognitive skills were examined.

METHOD

One hundred and forty-five children aged between 7 and 14 (103 males, M = 8.88 years, ethnicity representative of the wider Australian population) were randomly assigned to PMT and CPS. Assessment was conducted at baseline, post-intervention, and at 6-month follow-up, using independently rated semi-structured diagnostic interviews and parent-ratings of ODD symptoms. Using an intent-to-treat sample in this secondary analysis (Murrihy et al., 2022), linear regressions and PROCESS (Hayes, 2017) were used to examine these predictors and possible moderators of treatment.

RESULTS

Higher pre-treatment levels of conduct problems, lagging skills, and inconsistent discipline predicted poorer behavioral outcomes following both treatments. The only characteristic that moderated treatment outcome was child-responsible attributions - mothers who were more likely to attribute their child's problematic behaviors to factors in the child had significantly poorer outcomes in PMT than CPS at 6-month follow-up.

CONCLUSIONS

CPS may be a more beneficial treatment than PMT for families who have been identified as having higher levels of child-responsible attributions before commencing treatment for ODD. While tentative, this provides promising insights as to how treatment outcomes for children with ODD may be improved.

Parenting Profiles in Military Families: Intervention-Related Transitions and Relationships to Child Adjustment

Parenting programs aim to improve parenting quality, which may, in turn, support various aspects of child development, including behavior and mental health. However, parenting interventions show considerable heterogeneity in response patterns across different families, demonstrating that they are not one-size-fits-all programs. This variability points to a need for greater understanding of which families benefit most from these interventions and how to improve response among those who do not. Following this literature gap, this study employed a person-centered approach to identify different parenting profiles associated with heterogeneity in treatment responses to a family-based prevention interventions adapted for military families. This study used data from a randomized controlled trial of the ADAPT intervention for 336 US military families in which at least one parent had deployed to war. Latent profile analyses revealed three unobserved parenting profiles among mothers and fathers, reflecting High positive, Moderate positive, and Coercive parenting styles. Latent transition analysis (LTA) suggested that the ADAPT program led to improvements in parenting, particularly among mothers who began the program with moderate or typical levels of parenting skills, and that these positive changes in parenting may help to decrease child externalizing problems. For fathers, the ADAPT program was most effective in preventing declines in positive parenting among those with initially typical levels of positive parenting. Overall, study findings demonstrate considerable heterogeneity in parenting behavior among a sample of military families that is associated with variability in parent responses to the evidence-based parenting program.

Family Check-Up Online: Effects of a Virtual Randomized Trial on Parent Stress, Parenting, and Child Outcomes in Early Adolescence

We adapted the Family Check-Up Online (FCU-O) (1) to support families coping with pandemic-related stressors to prevent behavioral and emotional problems among middle school youth and (2) for smartphone delivery to increase access and reach during the COVID-19 pandemic. This study evaluated the direct and indirect effects of the adapted FCU-O at 4-months post-baseline. The FCU-O combines online parenting support with telephone coaching. Participants were primary caregivers of children ages 10 to 14 years. Eligibility included endorsing depression on the PHQ-2 or significant stress on a 4-item version of the Perceived Stress Scale. We randomly assigned participants to the adapted FCU-O (N = 74) or a waitlist control condition (N = 87). Participants predominantly self-identified as female (95%), 42.77 years old on average, and White (84.6%). Outcomes included caregiver reports of perceived stress and parenting, and youth conduct problems and depressive symptoms. Using a multilevel modeling approach, we tested intent-to-treat intervention effects at 4-months, with time points nested within participants. The FCU-O reduced caregiver stress and improved proactive parenting and limit setting but had no effects on youth outcomes. Effect sizes were small to moderate (Cohen's d ranged from .37 to .57). We examined indirect effects on youth outcomes at 4-months via changes in caregiver stress and parenting at 2-months. Mediation analyses suggested indirect effects on youth depressive symptoms via reductions in caregiver stress and increases in proactive parenting. Results indicate the FCU-O has potential as a public health intervention for families facing extreme stressors such as those during the COVID-19 pandemic. ClinicalTrials.gov Identifier: NCT05117099.

Is internet-based parent training for everyone? Predictors and moderators of outcomes in group vs. internet-based parent training for children with disruptive behavior problems

Parent training is an effective treatment for disruptive behavior problems in children. However, as there is limited access to traditional face-to-face treatment, other delivery formats have been evaluated. This study aims to evaluate possible predictors and moderators of outcome, completion and engagement in parent training when delivered in group or through the internet. A recent randomized controlled non-inferiority trial (N = 161) demonstrated equal effectiveness of the parent training program Comet when delivered in group (gComet) and through the internet (iComet). Demographic, clinical and theory-driven variables were studied to find predictors and moderators of treatment effect, completion and engagement. Linear mixed effects models were used to determine predictors and moderators of change in disruptive behavior from baseline to the 3- and 12-month follow-up. Most variables did not have significant predictive or moderating effects. However, there were some variables that predicted or moderated outcomes that may have implications for practice (e.g., comorbid emotional problems, preferred treatment format, and ADHD). This trial can contribute to guiding clinical work with children with disruptive behavior and results indicate that parent training in both treatment formats can be offered regardless of a range of demographic and clinical factors. Taking patients' treatment preferences into account can increase treatment completion.

Exploring Parenting Profiles to Understand Who Benefits from the Incredible Years Parenting Program

Behavioral parenting programs are a theory-driven and evidence-based approach for reducing disruptive child behavior. Although these programs are effective on average, they are not equally effective in all families. Decades of moderation research has yielded very few consistent moderators, and we therefore still have little knowledge of who benefits from these programs and little understanding why some families benefit more than others. This study applied a baseline target moderation model to a parenting program, by (1) identifying parenting profiles at baseline, (2) exploring their correlations with other family characteristics and their stability, and (3) assessing whether they moderate intervention effects on child behavior. Individual participant data from four Dutch studies on the Incredible Years (IY) parenting program were used (N = 785 caregiver-child dyads). Children (58.2% boys) were at risk of disruptive behavior problems and aged between 2 and 11 years of age (M = 5.85 years; SD = 1.59). Latent profile analyses indicated three distinct baseline parenting profiles, which we labeled as follows: Low Involvement (81.4%), High Involvement (8.4%), and Harsh Parenting (10.1%). The profiles caregivers were allocated to were associated with their education, minority status, being a single caregiver, and the severity of disruptive child behavior. We found neither evidence that baseline parenting profiles changed due to participation in IY nor evidence that the profiles predicted program effects on child behavior. Our findings do not support the baseline target moderation hypothesis but raise new questions on how parenting programs may work similarly or differently for different families.

Changes in Prosocial Behaviors Among Children With Behavioral Problems Following Incredible Years Parenting Program

Parenting programs often train parents in improving their parenting practices and parent-child relationship to reduce behavioral problems in children. However, the children's prosocial behaviors are less examined as an intervention outcome in these programs. This study aimed to evaluate the effectiveness of the Incredible Years parenting program (IYPP) for Malaysian parents of school-going children and its sustainability in improving the children's prosocial behaviors. This randomized controlled study involved pre- and post-intervention assessments at 2 and 14 weeks. Mothers of children aged 6-12 years (n = 70) recruited through the pediatrics and the child and adolescent psychiatric clinics were randomly assigned to the parenting program or a waitlist control condition. The mothers rated their children's prosocial behaviors using a self-administered questionnaire. The program ran two to three hours weekly for 14 weeks. Several modifications were made to the program to accommodate public health control during the pandemic. Children in the intervention group showed a notable but non-significant increase in prosocial skills. However, subsequent score decline at follow-up may suggest a lack of evidence that the program is potentially effective in improving prosocial behaviors among school children who are at risk of or already having behavioral problems.

Parent and Child Risk Profiles as Predictors of Response to a Conduct Problem Preventive Intervention

Current evidence-based prevention programming targeting child externalizing problems demonstrates modest overall effect sizes and is largely ineffective for a sizable proportion of youth who participate. However, our understanding of the youth and family characteristics associated with response to specific programming is quite limited. The current study used child and family risk profiles as predictors of response trajectories to the Early Risers conduct problem preventive intervention. A sample of 240 kindergarten-aged youth displaying elevated school-based aggression were randomized by school to either the Early Risers intervention or a control condition. Using a number of child and family risk variables, a latent profile analysis produced a solution consisting of five unique risk profiles. Three low and mixed risk profiles were associated with a limited response to the intervention. One high-risk profile characterized by maladaptive parenting and elevated child externalizing demonstrated notably improved trajectories of externalizing behavior over a 3-year period relative to the control condition. Another high-risk profile characterized by inconsistent discipline, high parental distress, and elevated child internalizing and externalizing symptoms seemed to have positive developmental trends disrupted by the intervention relative to the control condition, potentially consistent with an iatrogenic effect relative to the control condition. The study results support continued efforts to use broader risk profiles to examine heterogeneity in response to preventive interventions and, with replication, will have implications for intervention tailoring.

Longer-Term Outcomes of the Incredible Years Parenting Intervention

Conduct problems can develop into behavior disorders and put children at risk for other mental health problems. Parenting interventions have been shown to successfully reduce conduct problems and are often expected to prevent the development of broader mental health problems. Few studies have evaluated the longer-term and broader effects of these interventions. To what extent are parenting intervention effects sustained in the years after the intervention? And do effects pertain to conduct problems specifically, or do they also affect broader aspects of children's mental health? We used a randomized controlled trial to assess the longer-term (2.5 years) effects of the Incredible Years parenting intervention on children's conduct problems in an indicated prevention setting (N = 387; 79% retention rate). Using a multi-method (survey and computerized tasks) and multi-informant (parents, teachers, and children) approach, we tested whether initial effects on conduct problems were sustained, and whether Incredible Years had broader effects on children's peer problems, emotional problems, attention-deficit/hyperactivity disorder (ADHD) symptoms, attention and inhibition deficits, and service use. Incredible Years, relative to control (no intervention), led to sustained reductions in parent-reported conduct problems (Cohen's d = 0.31), but not teacher- and child-reported conduct problems. There were no broader benefits: Incredible Years did not reduce children's peer problems, emotional problems, ADHD-symptoms, attention and inhibition deficits, or their service use. Improvements in parents' perceptions of child conduct problems sustained until 2.5 years later. Our findings do not show benefits of Incredible Years as a preventive intervention for children's broader mental health.

Moderators of Psychosocial Intervention Response for Children and Adolescents with Conduct Problems

Objective: The purpose of this Brief Report is to synthesize the current evidence base examining moderators of psychosocial intervention response for children and adolescents with conduct problems (CP). We also provide directions for future research.Method: We focused on four categories of psychosocial interventions for the prevention and/or treatment of CP: (1) parent management training (PMT) for children, (2) other family-based interventions for adolescents, (3) youth skills training, and (4) multicomponent interventions (i.e., family-based intervention plus skills training). Emphasis is placed on findings from meta-analyses.Results: Moderation analyses have occurred more frequently for PMT than for other types of interventions. Variables for which there was consistent evidence for positive moderation included higher initial severity of CP, father engagement, higher maternal depressive symptoms, individual administration (vs. group), and treatment/targeted prevention approaches (vs. universal prevention). Variables where there was evidence for no moderation (demonstrating generalizability) included child diagnostic status and family risk in PMT, and diagnostic status and intervention setting for skills training. However, for some variables, evidence of moderation was dependent on intervention type.Conclusions: Future research should examine multiple moderators in combination; incorporate innovative techniques such as integrative data analyses, individual participant data, and class-based modeling, which may identify moderator effects that are undetected by more traditional variable-oriented moderation analyses; and conduct moderated mediation models for informing developmental theory on the interplay of risk and protective factors.

Increasing Effectiveness of Cognitive Behavioral Therapy for Conduct Problems in Children and Adolescents: What Can We Learn from Neuroimaging Studies?

Cognitive behavioral therapy (CBT) is particularly relevant for children from 7 years on and adolescents with clinical levels of conduct problems. CBT provides these children and adolescents with anger regulation and social problem-solving skills that enable them to behave in more independent and situation appropriate ways. Typically, CBT is combined with another psychological treatment such as behavioral parent training in childhood or an intervention targeting multiple systems in adolescence. The effectiveness of CBT, however, is in the small to medium range. The aim of this review is to describe how the effectiveness of CBT may be improved by paying more attention to a series of psychological functions that have been shown to be impaired in neuroimaging studies: (1) anger recognition, (2) the ability to generate situation appropriate solutions to social problems, (3) reinforcement-based decision making, (4) response inhibition, and (5) affective empathy. It is suggested that children and adolescents first become familiar with these psychological functions during group CBT sessions. In individual sessions in which the parents (and/or child care workers in day treatment and residential treatment) and the child or adolescent participate, parents then learn to elicit, support, and reinforce their child’s use of these psychological functions in everyday life (in vivo practice). In these individual sessions, working on the psychological functions is tailored to the individual child’s characteristic impairments of these functions. CBT therapists may also share crucial social-learning topics with teachers with a view to creating learning opportunities for children and adolescents at school.

When mummy and daddy get under your skin: A new look at how parenting affects children's DNA methylation, stress reactivity, and disruptive behavior

Child maltreatment is a global phenomenon that affects the lives of millions of children. Worldwide, as many as one in three to six children encounter physical, sexual, or emotional abuse from their caregivers. Children who experience abuse often show alterations in stress reactivity. Although this alteration may reflect a physiological survival response, it can nevertheless be harmful in the long run-increasing children's disruptive behavior and jeopardizing their development in multiple domains. But can we undo this process in at-risk children? Based on several lines of pioneering research, we hypothesize that we indeed can. Specifically, we hypothesize that highly dysfunctional parenting leads to an epigenetic pattern in children's glucocorticoid genes that contributes to stress dysregulation and disruptive behavior. However, we also hypothesize that it is possible to "flip the methylation switch" by improving parenting with known-effective parenting interventions in at-risk families. We predict that improved parenting will change methylation in genes in the glucocorticoid pathway, leading to improved stress reactivity and decreased disruptive behavior in children. Future research testing this theory may transform developmental and intervention science, demonstrating how parents can get under their children's skins-and how this mechanism can be reversed.

Individual Participant Data Meta-analysis: Impact of Conduct Problem Severity, Comorbid Attention-Deficit/Hyperactivity Disorder and Emotional Problems, and Maternal Depression on Parenting Program Effects

OBJECTIVE

There is concern whether established parenting programs for children's conduct problems meet the needs of families with severe and complex mental health problems. For example, many children with conduct problems show comorbid attention-deficit/hyperactivity disorder (ADHD) or emotional problems, or have parents who are depressed, but families with such complex mental health problems typically seen in real life are often underrepresented in evaluation trials. We tested whether children with more severe conduct problems, and those with more complex mental health problems, benefit less from the Incredible Years parenting program, using individual participant data meta-analysis of randomized trials in Europe.

METHOD

In 1,696 families from 13 children aged (child age 2-11 years; 37% girls; 58% low income; 30% ethnic minority; 98% mothers), we used moderator analysis within a multilevel model to test whether initial conduct problem severity, comorbid ADHD or emotional problems, and maternal depression would diminish intervention effects for children's conduct problems.

RESULTS

The Incredible Years program reduced children's conduct problems overall (Cohen's d = -0.35), but more so in children with more severe conduct problems. There was no evidence that children's comorbid ADHD and emotional problems changed the intervention benefits. Children of mothers with more depressive symptoms benefited more.

CONCLUSION

Children with more severe conduct problems derive greater, rather than lesser, benefits from a high-quality group parenting program, and comorbid ADHD and emotional problems do not reduce effects; maternal depression, rather than being linked to less child change, was associated with greater reductions in children's conduct problems.

Editors' Best of 2019

There is, in the content of the Journal, an embarrassment of riches, and picking a "best" seems to demand a certain qualification: is the "best" the most interesting, most surprising, most educational, most important, most provocative, most enjoyable? How to choose? We are hardly unbiased and can admit to a special affection for the ones that we and the authors worked hardest on, hammering version after version into shape. Acknowledging these biases, here are the 2019 articles that we think deserve your attention or at least a second read.

Co-occurring change in children's conduct problems and maternal depression: Latent class individual participant data meta-analysis of the Incredible Years parenting program

Children vary in the extent to which they benefit from parenting programs for conduct problems. How does parental mental health change if children benefit less or more? We assessed whether changes in conduct problems and maternal depressive symptoms co-occur following participation in the Incredible Years parenting program. We integrated individual participant data from 10 randomized trials (N = 1280; children aged 2–10 years) and distinguished latent classes based on families' baseline and post-test conduct problems and maternal depressive symptoms, using repeated measures latent class analysis (RMLCA) and latent transition analysis (LTA). Classes differed mainly in severity of conduct problems and depression (RMLCA; 4 classes). Conduct problems reduced in all classes. Depressive symptoms did not change in most classes, except in a class of families where conduct problems and depression were particularly severe. Incredible Years led to a greater likelihood of families with particularly severe conduct problems and depression moving to a class with mild problems (LTA; 3 classes). Our findings suggest that for the majority of families, children's conduct problems reduce, but maternal depressive symptoms do not, suggesting relative independence, with the exception of families with severe depression and severe conduct problems where changes for the better do co-occur.
