The Ws of Parental Help-Seeking: When, Where, and for What Do Parents Seek Help for Child Mental Health.

Parental help-seeking preferences may help explain the treatment gap in child mental health. This study examined mothers' and fathers' help-seeking behaviors for child mental health to further understand their individual preferences for treatment. A total of 394 mothers and fathers completed questionnaires assessing the types of help sought for mental health concerns for a target child (age 3-7 years), as well as measures representing illness profile, predisposing characteristics, and barriers/facilitators proposed to influence help-seeking. Parents often sought informal rather than professional help. Regression modelling indicated mothers' different help-seeking behaviors were significantly associated with illness profile (marital quality, child mental health, parental education), predisposing factors (parental attributions, child age), and family income, while fathers' different help-seeking behaviors were significantly associated with child demographics (age, gender). The results support expanding treatments into nonclinical settings and improving child mental health literacy to improve appropriate parental help-seeking for child mental health concerns.

Parents' illness representations of their child with anorexia nervosa: A systematic review of qualitative studies using the common-sense model.

OBJECTIVE: Research indicates that parents experience distress while caring for a child with anorexia nervosa. Applying the Common Sense Model of Self-Regulation (CSM), a framework to describe responses to illness may help to understand the antecedents of parental distress, which could inform how to support parents in treatment. The aim of this systematic review was to synthesize outcomes from qualitative research in relation to parents' experiences of caring for a child with anorexia nervosa using the CSM. METHOD: Systematic search of four electronic databases (psychINFO, MEDLINE, EMBASE, ProQuest Dissertation, and Theses Database) alongside a two-way screening process was used to identify eligible studies. Qualitative themes were synthesized using a "best fit" framework analysis and reported according to CSM dimensions of cognitive and emotional illness representations. RESULTS: A total of 32 studies published between 1970 and 2023 were eligible for inclusion for review. Parents perceived their child's anorexia nervosa as a major health threat observable by illness representations that anorexia nervosa was uncontrollable, incomprehensible, chronic, and associated with negative consequences. The themes also suggested parents take responsibility for causing anorexia nervosa. These illness representations were linked with emotional representations of fear, anxiety, shame, guilt, loneliness, and depression. CONCLUSIONS: The findings provide evidence of the utility of using the CSM to understand the antecedents of parents' distress and negative impacts of caring for a child with anorexia nervosa. Recommendations for future research and clinical practice are discussed emphasizing the need to understand parents' perceptions of their child's illness to putatively maximize treatment benefits for families. PUBLIC SIGNIFICANCE: This review emphasizes the salience of understanding parents distress while caring for a child with anorexia nervosa. The findings present opportunities to best support parents in treatment, with a focus on addressing their cognitive and emotional representations of their child's illness. A multicomponent treatment regimen may be required to support parents if they present with illness representations that negatively affect their well-being and ability to cope with distress.

OBJETIVO: Las investigaciones indican que los padres experimentan angustia mientras cuidan a un hij@ que padece anorexia nerviosa. La aplicación del modelo de autorregulación del sentido común (Common Sense Model of Self-Regulation, CSM), un marco para describir las respuestas a la enfermedad, puede ayudar a comprender los antecedentes de la angustia de los padres, lo que podría informarnos sobre cómo apoyar a los padres en el tratamiento. El objetivo de esta revisión sistemática fue sintetizar los resultados de la investigación cualitativa en relación con las experiencias de los padres en el cuidado de un hij@ que padece anorexia nerviosa utilizando el CSM. MÉTODO: Se realizó una búsqueda sistemática en cuatro bases de datos electrónicas (psychINFO, MEDLINE, EMBASE, ProQuest Dissertation and Theses Database) junto con un proceso de selección bidireccional para identificar los estudios elegibles. Los temas cualitativos se sintetizaron mediante un análisis del marco de "mejor ajuste" y se presentaron de acuerdo con las dimensiones del MCS de las representaciones cognitivas y emocionales de la enfermedad. RESULTADOS: 32 estudios publicados entre 1970 y 2023 fueron elegibles para su inclusión en la revisión. Los padres percibían la anorexia nerviosa de sus hij@s como una amenaza importante para la salud observable por las representaciones de enfermedad de que la anorexia nerviosa era incontrolable, incomprensible, crónica y asociada a consecuencias negativas. Los temas también sugerían que los padres asumían la responsabilidad de causar la anorexia nerviosa. Estas representaciones de la enfermedad estaban vinculadas a representaciones emocionales de miedo, ansiedad, vergüenza, culpa, soledad y depresión. CONCLUSIONES: Los hallazgos proporcionan evidencia de la utilidad de utilizar el CSM para comprender los antecedentes de la angustia de los padres y los impactos negativos de cuidar a un hij@ que padece anorexia nerviosa. Se discuten recomendaciones para futuras investigaciones y prácticas clínicas, enfatizando la necesidad de comprender las percepciones de los padres sobre la enfermedad de sus hij@s para maximizar los beneficios del tratamiento para las familias.

The Rating of Emotional Abuse in Childhood (REACH) Questionnaire: A new self-report measure assessing history of childhood emotional abuse.

BACKGROUND: A history of childhood emotional abuse (CEA) is prevalent among adults with affective disorders; therefore, a comprehensive measure of it is vital. The Rating of Emotional Abuse in Childhood Questionnaire (REACH) was developed to assess history of CEA in relation to parental behaviours of threat, ignoring, humiliation/denigration, scapegoating, antipathy, and overcontrol/conditionality in a single measure. This paper investigated the psychometric properties of REACH in a community sample and proposes values for classifying individuals as high-risk for CEA. METHOD: A convenience sample of N = 483 adults (Female, 78.3%) was recruited to complete questionnaires that included the REACH alongside measures of mental health, insecure attachment, emotion regulation, and childhood abuse. A subset of participants (n = 198) completed the REACH 7 days later. RESULTS: Factor analysis indicated a 2-factor model provided a good fit. Factors were named 'threatening' and 'devaluing'. A total scale score of CEA was also recommended. The threatening, devaluing, and total scales demonstrated strong psychometric properties with high internal consistency, test-retest reliability, and convergent validity, while cutoff values for identifying a high-risk CEA group demonstrated good discriminant utility. CONCLUSIONS: The results support REACH as a valid measure and suggest a history of CEA should be measured in relation to threatening and devaluing CEA as they represent unique dimensions of CEA even though they often co-occur.

Digital Application of Clinical Staging to Support Stratification in Youth Mental Health Services: Validity and Reliability Study.

BACKGROUND: As the demand for youth mental health care continues to rise, managing wait times and reducing treatment delays are key challenges to delivering timely and quality care. Clinical staging is a heuristic model for youth mental health that can stratify care allocation according to individuals' risk of illness progression. The application of staging has been traditionally limited to trained clinicians yet leveraging digital technologies to apply clinical staging could increase the scalability and usability of this model in services. OBJECTIVE: The aim of this study was to validate a digital algorithm to accurately differentiate young people at lower and higher risk of developing mental disorders. METHODS: We conducted a study with a cohort comprising 131 young people, aged between 16 and 25 years, who presented to youth mental health services in Australia between November 2018 and March 2021. Expert psychiatrists independently assigned clinical stages (either stage 1a or stage 1b+), which were then compared to the digital algorithm's allocation based on a multidimensional self-report questionnaire. RESULTS: Of the 131 participants, the mean age was 20.3 (SD 2.4) years, and 72% (94/131) of them were female. Ninety-one percent of clinical stage ratings were concordant between the digital algorithm and the experts' ratings, with a substantial interrater agreement (κ=0.67; P<.001). The algorithm demonstrated an accuracy of 91% (95% CI 86%-95%; P=.03), a sensitivity of 80%, a specificity of 93%, and an F1-score of 73%. Of the concordant ratings, 16 young people were allocated to stage 1a, while 103 were assigned to stage 1b+. Among the 12 discordant cases, the digital algorithm allocated a lower stage (stage 1a) to 8 participants compared to the experts. These individuals had significantly milder symptoms of depression (P<.001) and anxiety (P<.001) compared to those with concordant stage 1b+ ratings. CONCLUSIONS: This novel digital algorithm is sufficiently robust to be used as an adjunctive decision support tool to stratify care and assist with demand management in youth mental health services. This work could transform care pathways and expedite care allocation for those in the early stages of common anxiety and depressive disorders. Between 11% and 27% of young people seeking care may benefit from low-intensity, self-directed, or brief interventions. Findings from this study suggest the possibility of redirecting clinical capacity to focus on individuals in stage 1b+ for further assessment and intervention.

Thinking about the next generation: The case for a mentalization-informed approach to perinatal and intergenerational mental health.

BACKGROUND: There has been substantial progress made across multiple disciplines to emphasize the importance of perinatal mental health both for parents and offspring. This focuses on what has been termed the 'First 1000 Days' from conception to the child's second birthday. We argue that our understanding of this issue can go further to create an intergenerational approach to mental health. Despite the existence of theoretical frameworks and practical approaches to implementation, there are gaps in the understanding of perinatal and intergenerational mental health including which psychological mechanisms are implicated in the transmission of risk and resilience within the perinatal period; and how to leverage these into treatment approaches. AIMS AND METHODS: In this paper, we explore the potential for mentalization as a candidate psychological approach to intergenerational mental health. RESULTS: We contextualize this issue in terms of the points of contact between mentalization and broader theoretical models such as the social determinants of health and the Developmental Origins of Health and Disease (DoHaD) model. Further, we provide an overview of the existing evidence base for the relevance of mentalization to perinatal mental health. DISCUSSION: Finally, we sketch out an outline model for integrating mentalization into perinatal and intergenerational mental health, highlighting several areas of opportunity to develop research and practice from diverse geographies and demographics. Here, we suggest that integration of mentalization with other conceptual frameworks such as DoHaD can mutually enrich the understanding of each model, pointing the way towards more effective early and preventative interventions.

An examination of behavioural and emotional problems in children exposed prenatally to the 27F Chilean earthquake: findings from the ELPI cohort.

PURPOSE: Associations between prenatal earthquake exposure and children's mental health remain unclear. Moreover, there is a paucity of research using quasi-experimental statistical techniques to diminish potential selection bias. Thus, this study aimed to explore the impact of prenatal exposure to the Chilean earthquake of 2010 on children's behavioural and emotional problems between 1½ and 3 years old using propensity score matching. METHODS: Participants included 1549 families from the Encuesta Longitudinal de la Primera Infancia cohort in Chile. Maternal reports using the Child Behaviour Checklist (CBCL) were used to assess behavioural and emotional problems between 1½ and 3 years old. Information on prenatal earthquake exposure was collected via maternal report. The Kernel matching estimator was used to compare the average treatment effects of children who were exposed to the earthquake compared to those who were not. RESULTS: Five of the seven CBCL outcomes were statistically significant after matching and adjustment for multiple testing, suggesting greater difficulties for exposed children which included emotional reactivity, anxious/depressed, sleep problems, attention problems, and aggression (mean difference of 0.69, 0.87, 0.73, 0.85, 3.51, respectively). The magnitude of the effect was small to medium. CONCLUSION: Findings contribute to the potential causal inferences between prenatal earthquake exposure and increased behavioural and emotional problems in early childhood. Results suggest that in utero experiences may have long-term consequences for infants' well-being, supporting the need for specific interventions in pregnancy after natural disasters.

Global Workforce Development in Father Engagement Competencies for Family-Based Interventions Using an Online Training Program: A Mixed-Method Feasibility Study.

Global access to practitioner training in the clinical engagement of fathers in family-based interventions is limited. The current study evaluated the feasibility of training practitioners in Canada and UK using online training developed in Australia by examining improvements in practitioner confidence and competence in father engagement, training satisfaction, qualitative feedback, and benchmarking results to those from an Australian sample. Practitioners were recruited to participate in a 2-h online training program through health services and charity organisations. The online program required practitioners to watch a video and complete self-reflection exercises in a digital workbook. Pre- and post-training measures were collected immediately before and after the online training program. The results indicated significantly large improvements in self-reported confidence and competence in engaging fathers following training, with levels of improvement similar to those found in Australia. Training satisfaction was high and qualitative feedback suggested providing local resources and increasing representation of social diversity could improve training relevance in local contexts. The findings suggest online training in father engagement can contribute to global workforce development in improving practitioners' skills in engaging fathers in family-based interventions.

Strategic Priorities for Implementation of Father-Inclusive Practice in Mental Health Services for Children and Families: A Delphi Expert Consensus Study.

The aim of this study was to investigate expert consensus on barriers and facilitators to the organizational implementation of Father-Inclusive Practice (FIP) in child and family services to establish strategic priorities for implementation. An international panel of 56 experts in child and family service provision and father inclusion were surveyed using the Delphi technique. Three online questionnaires were used to gather opinions and measure experts' levels of agreement in regard to factors that enable or hinder the organizational implementation of FIP. Survey design, analysis and interpretation was guided by the Consolidated Framework for Implementation Research (CFIR). Consensus was achieved for 46.4% (n = 13) statements. Eight barriers and five facilitators were identified as strategic priorities to organizational implementation of FIP. The key factors were related to the following CFIR themes: leadership engagement, access to information and knowledge, implementation climate, structural characteristics, networks and communication, client needs and resources, external policies and incentives, and reflecting and evaluating. The study findings suggest that issues related to central prioritization, top-down organizational processes and external policy context should represent priority areas for implementation. Our results prioritise methods for improving FIP by highlighting the key areas of organizational practice to be addressed by tailored implementation strategies.

Does behavioural parent training reduce internalising symptoms (or not) among children with externalising problems? Systematic review and meta-analysis.

Behaviour parent training (BPT) is known to effectively reduce child externalising problems. However, evidence for BPT to have secondary benefits for reducing internalising symptoms remains unclear. To address this, electronic databases (PsycINFO, MEDLINE, EMBASE, CINAHL, and SCOPUS) were systematically searched for studies examining internalising outcomes from BPT among children aged 2-12 years with clinically elevated externalizing problems. Outcomes for internalising problems following BPT were analysed by meta-analysis. Of 9105 studies identified, 24 studies met the eligibility criteria. Results from meta-analysis demonstrated a significant small treatment effect size (g = - 0.41) for reducing internalising symptoms immediately after treatment. Studies showed moderate heterogeneity (I2 = 44%). Moderation analyses indicated that the overall treatment effect was robust against variations in treatment and study design characteristics. However, a review of individual study methods indicate that these results are limited by significant heterogeneity and limitations in clinical assessment. Overall, the results suggest that BPT programmes for reducing externalising problems have the potential to improve internalising outcomes, but that there is limited information to determine the reliability of these effects, highlighting the need for further investigation.

Multiple needs and multiple treatments. What's a clinician to do? Update on the psychosocial treatment of disruptive behaviours in childhood.

PURPOSE OF REVIEW: There are a wide range of psychosocial treatment options, delivered in different modalities, for children with disruptive behaviour. However, clinicians face many challenges in ensuring the empirically supported treatments (ESTs) they select will be effective for their patient. This has prompted studies to generate knowledge on how to improve treatment outcomes for children with disruptive behaviour. This review identifies the major challenges in treatment selection as well as emerging research seeking to improve outcomes. RECENT FINDINGS: This review emphasizes the salience of the research-practice gap associated with establishing ESTs using narrow definitions of clinical problems. Recent research is reviewed considering the complex determinants of disruptive behaviours, including parent and family factors that influence outcomes. The review subsequently outlines recent advances in research and clinical practice guidelines aiming to surmount these challenges. Key advances discussed include examining the most impactful components of ESTs, personalizing interventions by targeting core dysfunction underlying behaviour, and addressing parent factors including mental health and cultural relevance to improve outcomes. SUMMARY: Thorough assessment of patients' needs, combined with knowledge of treatment response predictors, are recommended to determine the most suitable treatment plan. Recent advances have focused on developing and designing interventions that meet needs in a way that is flexible and tailored.

Do attachment-related differences in reflective functioning explain associations between expressed emotion and youth self-harm?

Youth self-harm is associated with poor health outcomes and attempted and completed suicide. Associations exist between self-harm and expressed emotion (EE), attachment insecurity, and reflective functioning (RF), but these associations are poorly understood. This study evaluates a mediation model in which perceived caregiver EE (pEE) exerts an indirect effect on youth self-harm through attachment insecurity and RF uncertainty. 461 participants aged 16-24 years completed an online survey. Statistical analyses revealed significant direct effects of pEE on attachment insecurity, and of RF uncertainty on self-harm; however, some direct effects were specific to pEE from female caregivers, and attachment insecurity in youth relationships with female caregivers. A significant direct effect of pEE on self-harm was found for pEE from male caregivers only. Significant indirect effects of pEE on self-harm through attachment anxiety and RF uncertainty were found only in relation to female caregivers. The findings encourage family-, attachment-, and mentalization-based approaches to preventing and treating youth self-harm, with a recommendation that caregivers are given adequate support, education, and skills-based training following youth disclosures of self-harm.

Psychosocial interventions for depression delivered by non-mental health specialists to people living with HIV/AIDS in low- and middle-income countries: A systematic review.

Background: Depression commonly co-exists with human immunodeficiency virus (HIV), but in low- and middle-income countries (LMICs), where the HIV burden is greatest, mental health resources are limited. These settings may benefit from psychosocial interventions delivered to people living with HIV/AIDS (PLWH) by non-mental health specialists. We aimed to systematically review randomised controlled trials (RCTs) that investigated the effectiveness of psychosocial interventions delivered by non-mental health specialists to prevent depression in PLWH in LMICs. Methods: We used a comprehensive electronic search strategy to identify RCTs of any stage, including pilot studies, which reported on the effectiveness of a psychosocial intervention on depression among adults living with HIV/AIDS in a LMIC setting. Screening, study selection and data extraction was completed independently by two authors. We assessed risk of bias using the Cochrane risk of bias (RoB) tool and performed a narrative synthesis. Results: We identified 3431 studies, from which we included 15 studies corresponding to 14 RCTs and a total of 3997 PLWH. Eleven studies were parallel RCTs, one was a stepped-wedged RCT, one was a full factorial RCT, one was a three-arm RCT and four were pilot studies. Studies were generally small, with eight including depression as a primary outcome. All but four trials included men and women and most studies followed participants for less than one year. Twelve trials had at least one domain in which there was a high risk of bias, with the remaining two trials having at least one domain of concern, due to lack of reporting of items. In 12 studies people in the intervention arm had statistically significantly (P < 0.05) lower or more reduced depressive symptom scores, or were less likely to have major depression, at final follow-up than people in the control group. Conclusions: Psychosocial interventions delivered by non-specialist mental health workers may be effective in preventing or reducing depression in PLWH in LMICs. However, existing studies are small with a relatively short follow-up period and have methodological limitations. Future trials should address these shortcomings, establish whether intervention effects are clinically meaningful and investigate cost-effectiveness.

Barriers and Facilitators to Engaging Mothers and Fathers in Family-Based Interventions: A Qualitative Systematic Review.

The current systematic review examined the similarities and differences between mothers' and fathers' reported barriers and facilitators to engaging in family-based interventions for child and adolescent behavioural problems (aged 2-17 years). Systematic searches of six electronic databases and grey literature alongside a two-way screening process identified twenty eligible qualitative studies from 2004 to 2019. A thematic meta-synthesis identified similarities in major themes of psychological, situational, knowledge/awareness, programme/intervention, co-parenting, practitioner, and beliefs/attitudes factors, alongside group experiences and stages of engagement. However, differences emerged in subthemes related to parental, treatment, and service delivery factors that included individual ideologies of parenting, parental roles, and treatment participation; the role of mothers in facilitating engagement; and individual preferences for treatment content and delivery. Overall, findings suggest that while mothers and fathers experience similar challenges to engagement, they can also experience distinct challenges which need to be addressed at the treatment outset to maximise engagement.

Transdiagnostic Clinical Staging for Childhood Mental Health: An Adjunctive Tool for Classifying Internalizing and Externalizing Syndromes that Emerge in Children Aged 5-11 Years.

Clinical staging is now recognized as a key tool for facilitating innovation in personalized and preventative mental health care. It places a strong emphasis on the salience of indicated prevention, early intervention, and secondary prevention of major mental disorders. By contrast to established models for major mood and psychotic syndromes that emerge after puberty, developments in clinical staging for childhood-onset disorders lags significantly behind. In this article, criteria for a transdiagnostic staging model for those internalizing and externalizing disorders that emerge in childhood is presented. This sits alongside three putative pathophysiological profiles (developmental, circadian, and anxious-arousal) that may underpin these common illness trajectories. Given available evidence, we argue that it is now timely to develop a transdiagnostic staging model for childhood-onset syndromes. It is further argued that a transdiagnostic staging model has the potential to capture more precisely the dimensional, fluctuating developmental patterns of illness progression of childhood psychopathology. Given potential improvements in modelling etiological processes, and delivering more personalized interventions, transdiagnostic clinical staging for childhood holds much promise for assisting to improve outcomes. We finish by presenting an agenda for research in developments of transdiagnostic clinical staging for childhood mental health.

Bridging the gap between child mental health need and professional service utilisation: Examining the influence of mothers' parental attributions on professional help-seeking intentions.

There is a significant gap between the need for child mental health services and use of these services by families. Parental attributions may play a role in this. This study examined whether mothers' attributions about their child's problems influence professional help-seeking intentions in a general sample of community mothers. Secondary analysis re-examined this hypothesis in a subgroup of mothers of children with clinically elevated mental health symptoms. Cross-sectional survey data were collected from mothers (N = 184) of children aged between 2 and 12 years recruited from the community. Mothers completed self-report questionnaires measuring parental attributions: child-responsible attributions and parental self-efficacy; professional help-seeking intentions; and psychosocial covariates: child mental health, mothers' anxiety and depression, child age, gender, marital status, education, and professional help-seeking experience. Hierarchical regression modelling indicated that parental attributions explained professional help-seeking intentions after controlling for covariates in both the general sample (ΔF = 6.07; p = .003) and subgroup analysis (ΔF = 10.22, p = .000). Professional help-seeking intentions were positively associated with child-responsible attributions (ß = .19, p = .002) but not parental self-efficacy (ß = - .01, p = .865) in the general sample, while positively associated with child-responsible attributions (ß = .20, p = .009) and negatively associated with parental self-efficacy (ß = - .16, p = .034) in the subgroup analysis. Findings were independent of the presence of clinically elevated symptoms, problem type, and severity. Overall, the findings support models suggesting that parental attributions have a role in professional help-seeking for child mental health problems.

Using Staged Care to Provide "Right Care First Time" to People With Common Affective Disorders.

An ongoing need exists for innovation in service delivery to ensure that mental health services deliver high-quality treatment and prevention in the population. This Special Article proposes the adoption of "staged care" as a population health-oriented service delivery model for packages of specialized services delivered largely in ambulatory care settings for individuals with common affective disorders. Staged care integrates measures of clinical need alongside clinical stage and personal choice to select hierarchically arranged service packages for individuals. Packages then vary according to the intensity, duration, and mix of treatment options. This Special Article describes five levels of care in staged care: self- or family-directed monitoring and management, low-intensity services, moderate-intensity services, high-intensity services, and acute and specialist community mental health services. The care environment, treatment team, and length of treatment are also described, and provisional criteria are specified for assigning individuals to different care levels on the basis of current clinical need and clinical stage. Staged care is presented as a model that guides treatment selection and health service delivery to ensure that the high-quality care aims of "right care first time" and prevention are achieved and optimal use of available resources is considered.

How Do Mothers' Parental Attributions Affect Child Outcomes from a Positive Parenting Intervention? A Mediation Study.

Problematic parental attributions refer to negative causal explanations for child problem behaviour and are known to predict parenting intervention outcomes. This study examines alternative accounts of how mothers' problematic parental attributions, operationalised as negative pre-treatment and change resistant parental attributions during treatment, may affect child behaviour outcomes from a parenting intervention program. Putative mediators included parental feelings about the child and use of harsh discipline. Participants were 163 families with children aged from 3 to 16 referred to specialist clinics for the treatment of conduct problems. Measures were collected as part of pre-treatment, post-treatment, and 3-month follow-up assessments. Mothers' pre-treatment and change resistant parental attributions were associated with smaller improvements in parental feelings at the end of treatment which in turn were associated with greater use of harsh discipline. Greater use of harsh discipline was associated with greater conduct problems overall. Smaller improvements in parental feelings mediated the effects of pre-treatment and change resistant parental attributions on outcomes in mothers' use of harsh discipline and mediated the effects of change resistant parental attributions on outcomes in child conduct problems. Smaller improvements in parental feelings about the child may act as a mechanism that explains the impact of problematic parental attributions on treatment outcomes.

ParentWorks: Evaluation of an Online, Father-Inclusive, Universal Parenting Intervention to Reduce Child Conduct Problems.

Evidence-based parenting interventions are effective in reducing conduct problems, yet these interventions have limited reach, and few involve the participation of fathers. This paper describes the outcomes of an open trial of ParentWorks, a universal, online, father-inclusive parenting intervention aiming to decrease childhood behavioural problems and promote positive parenting in mothers and fathers. A total of 388 families (456 individual parents; 36.6% fathers) were included in the study. Mixed model analyses showed significant decreases in child emotional/behavioural problems, dysfunctional parenting, interparental conflict, and parental mental health problems. The baseline severity of child behavioural problems significantly moderated the effects on child outcomes so that children with higher levels of problems benefitted more from the program. Participation of both caregivers in two-parent families, as well as parent sex, did not significantly affect the program outcomes. Results provide initial empirical support for the universal, self-directed, online parenting intervention, in addressing both child behavioural problems and parenting outcomes.
