Clinical Trial Summary

This study will evaluate whether the intervention, Mom Power, improves the self-regulation of mothers with a history of trauma and their children. The central hypothesis is that the intervention will shift behavioral and physiological self-regulation in mothers, children, and dyads to mitigate psychopathology risk.


Description:

Adverse childhood experiences (ACEs) are significant risk factors for psychopathology across the lifespan - risks that extend to the next generation, likely transmitted through both biological and behavioral pathways. Biobehavioral self-regulation and parenting are key candidates for transmission and potential points of intervention. However, nearly all intervention research takes a one-generation approach, measuring outcomes in the individual adult or child in treatment. Additionally, very little research has examined biomarkers of self-regulation in parents or children following treatment, and no known research has examined these processes in parents and young children simultaneously across treatment to explore bidirectional effects. There is a critical need to specify targets of two-generation interventions among high-adversity families to decrease intergenerational transmission of mental illness. The objective of this RCT is to determine whether Mom Power, an evidence-based two generation intervention for mothers with histories of trauma, enhances physiological and behavioral self-regulation in mothers and young children, testing mechanisms and examining bidirectional effects. The central hypothesis is that the intervention will shift behavioral and physiological (Respiratory Sinus Arrhythmia) self-regulation in mothers, children, and dyads to mitigate psychopathology risk. Three specific aims are proposed: 1) Examine intervention effects on children's biobehavioral self-regulation and psychopathology; 2) Examine intervention effects on mothers' biobehavioral self-regulation, psychopathology, and parenting behavior; and 3) Examine intergenerational change processes, including shifts in dyadic physiological and behavioral synchrony as well as bidirectional influences between mother and child self-regulation.

Study Design


Intervention

Behavioral:
Mom Power Intervention
Mom Power is a 10-week therapeutic intervention for at-risk families that incorporates elements of several evidence based practices. It combines didactic material with mindbody self-care skills and in vivo practice to improve the quality of attachment between parent and child, and to reduce the psychopathology of at-risk parents. The child team component provides each child with one-on-one care focusing on meeting the child's social-emotional needs and providing attachment-related experiences within a developmental framework.

Outcome

Type Measure Description Time frame Safety issue
Other Maternal social support Mothers will report on social support (Multidimensional Scale of Perceived Social Support); range: 12-84; higher scores reflect higher perceived support. Within 6 weeks of treatment group completion; approximately 4 months
Other Perceived stress Mothers will report on perceived stress (Perceived Stress Scale-4); range: 0-16; higher scores reflect higher stress Within 6 weeks of treatment group completion; approximately 4 months
Primary Child RSA Child self-regulation will be assessed physiologically with RSA baseline and RSA change during a parent-child dyadic task (Skowron et al., 2013); derived from electrocardiogram (ECG) collected using Mindware Technologies ambulatory mobile recorders during 1) 2-minute resting baseline; 2) a dyadic interaction task. ECG signals will be synchronized at acquisition with video and processed offline using Mindware software; research assistants will visually inspect for missing or erroneously identified R-peaks. Using spectral analysis of interbeat intervals, high-frequency heart rate variability will be extracted to quantify RSA within frequency bandwidths associated with respiration (.15-.40 for mothers; .24-1.04 for children), processed in 1-minute epochs averaged across tasks, and log-transformed. Within 6 weeks of treatment group completion; approximately 4 months
Primary Parent RSA Parent self-regulation will be assessed physiologically with RSA baseline and RSA change during a parent-child dyadic task (Skowron et al., 2013); derived from electrocardiogram (ECG) collected using Mindware Technologies ambulatory mobile recorders during 1) 2-minute resting baseline; 2) a dyadic interaction task. ECG signals will be synchronized at acquisition with video and processed offline using Mindware software; research assistants will visually inspect for missing or erroneously identified R-peaks. Using spectral analysis of interbeat intervals, high-frequency heart rate variability will be extracted to quantify RSA within frequency bandwidths associated with respiration (.15-.40 for mothers; .24-1.04 for children), processed in 1-minute epochs averaged across tasks, and log-transformed. Within 6 weeks of treatment group completion; approximately 4 months
Secondary Child Behavior - parent report Child Behavior problems will be assessed via Total Score on parent report with the Child Behavior Checklist; higher scores indicate higher behavior problems (T score is a standardized score with a mean of 50). Within 6 weeks of treatment group completion; approximately 4 months
Secondary Child Behavior - teacher report Child Behavior problems will be assessed via teacher report with the Teacher Report Form; Achenbach & Rescorla, 2000. Higher scores indicate higher behavior problems (T score is a standardized score with a mean of 50). Within 6 weeks of treatment group completion; approximately 4 months
Secondary Dyadic synchrony - physiological Dyadic synchrony will be assessed using EKG (derived from maternal and child RSA, as described above) Within 6 weeks of treatment group completion; approximately 4 months
Secondary Dyadic synchrony - observational Dyadic synchrony will be assessed observationally with the Coding Interactive Behavior (CIB) measure. Within 6 weeks of treatment group completion; approximately 4 months
Secondary Parent psychopathology Parents will report on their own depression symptoms (Patient Health Questionnaire-9 and Posttraumatic Checklist - 5); individual scales will be z-scored and summed, with higher values reflecting higher levels of psychopathology Within 6 weeks of treatment group completion; approximately 4 months
Secondary Parent emotion regulation Parents will report on their own emotion regulation using the difficulties in emotion regulation (DERS; range: 36-180); higher scores reflect more difficulties with emotion regulation. Within 6 weeks of treatment group completion; approximately 4 months
Secondary Sensitive parenting behavior Observational data derived from parent-child interactions will be examined, coding using the Coding Interactive Behavior measure (CIB). Higher scores reflect more sensitivity. Within 6 weeks of treatment group completion; approximately 4 months
Secondary Parent self-efficacy Parents will report on their own parenting efficacy using the Parent Sense of Competence scale; range: 17-102, higher scores reflect more self-efficacy Within 6 weeks of treatment group completion; approximately 4 months
Secondary Parenting behavior Parents will report on their own parenting behavior using the Conflict Tactic Scales - Parent Child (CTS-PC); range: 0-240, higher values reflect harsher parenting Within 6 weeks of treatment group completion; approximately 4 months
Secondary Parent mental representation Parents will complete an abbreviated version of the Working Model of the Child Interview; interviews will be coded into 3 categories, and it is hypothesized that proportion of "balanced" representations will be higher post-treatment. Within 6 weeks of treatment group completion; approximately 4 months
Secondary Child Behavioral Self-Regulation, observational Child self-regulation will be assessed behaviorally using observation (Preschool Self-Regulation Assessment); children's behavior will be observed during 6 tasks, and codes z-scored and summed; higher scores reflect higher effortful control/executive function Within 6 weeks of treatment group completion; approximately 4 months
Secondary Child Behavioral Self-Regulation, parent report Child self-regulation will also be assessed by parent-report (Social Competence Scale - Emotion Regulation); range: 0-48; higher scores reflect higher self-regulation Within 6 weeks of treatment group completion; approximately 4 months
