Baseline Targeted Moderation in a Trial of the Family Check-Up 4 Health: Potential Explanations for Finding Few Practical Effects

A budget impact analysis of cost to implement a whole child health focused, family-based intervention in primary care for children with elevated BMI

BACKGROUND

Although the cost of implementing evidence-based interventions (EBIs) is a key determinant of adoption, lack of cost information is widespread. We previously evaluated the cost of preparing to implement Family Check-Up 4 Health (FCU4Health), an individually tailored, evidence-based parenting program that takes a whole child approach, with effects on both behavioral health and health behavior outcomes, in primary care settings. This study estimates the cost of implementation, including preparation.

METHODS

We assessed the cost of FCU4Health across the preparation and implementation phases spanning 32 months and 1 week (October 1, 2016-June 13, 2019) in a type 2 hybrid effectiveness-implementation study. This family-level randomized controlled trial took place in Arizona with n = 113 predominantly low-income, Latino families with children ages > 5.5 to < 13 years. Using electronic cost capture and time-based activity-driven methods, budget impact analysis from the perspective of a future FCU4Health adopting entity-namely, ambulatory pediatric care clinicians-was used to estimate the cost of implementation. Labor costs were based on 2021 Bureau of Labor Statistics Occupational Employment Statistics, NIH-directed salary cap levels or known salaries, plus fringe benefits at a standard rate of 30%. Non-labor costs were based on actual amounts spent from receipts and invoices.

RESULTS

The cost of FCU4Health implementation to 113 families was $268,886 ($2380 per family). Actual per family cost varied widely, as individual tailoring resulted in families receiving a range of 1-15 sessions. The estimated cost of replicating implementation for future sites ranged from $37,636-$72,372 ($333-$641 per family). Using our previously reported preparation costs (i.e., $174,489; $1544 per family), with estimated replication costs of $18,524-$21,836 ($164-$193 per family), the total cost of delivering FCU4Health was $443,375 ($3924 per family), with total estimated replication costs of $56,160-$94,208 ($497-$834 per family).

CONCLUSIONS

This study provides a baseline for costs associated with implementation of an individually tailored parenting program. Results provide critical information for decision makers and a model for future economic analysis and can be used to inform optimization thresholds for implementation and, when necessary, benchmarks for program adaptation to promote scale-up.

When Is It Time to Revise or Adapt Our Prevention Programs? Introduction to Special Issue on Using Baseline Target Moderation to Assess Variation in Prevention Impact

Adaptation of preventive interventions to increase their impact can be advanced by identifying subgroups or specific contexts where program effects appear stronger or weaker. But how do we know where to look for effect heterogeneity in ways that will inform successful adaptation? This paper introduces a special issue that brings together research across prevention science sub-disciplines that adopted baseline target moderated mediation (BTMM) designs to search for effect heterogeneity and guide adaptation of established prevention programs. For this special issue intervention  scientists analyzed data from randomized trials using BTM and BTMM models, evaluating evidence for variation in intervention impact for trials spanning different health outcomes, different developmental periods, and different social units. This introduction provides a brief summary of the various patterns of effect reported in these papers, noting that the most common pattern involved compensatory effects (those beginning the trial with greater risk or fewer protective factors benefit the most), but other patterns including rich-get-richer and partially iatrogenic effects were also detected. This paper ends with a discussion of methodological and substantive implications of these findings for future prevention research, including next-generation prevention trials.

Baseline Target Moderation and Baseline Target Moderation Mediation Approaches: Reflections on Cultural Adaptation and Social Justice

Baseline target moderation (BTM) and baseline target moderated mediation (BTMM) constitute critical methodological and analytical approaches for the future of prevention science. However, the continuing refinement and utilization of these approaches carry important challenges when considering equity challenges that remain present in the prevention science field. Accordingly, this commentary is focused on examining cultural and contextual considerations associated with the set of articles included in this study, as well as directions for enhancing future research by embracing a solid grounding on equity perspectives. For example, to which extent do BTM and BTMM approaches include variables of relevance such as perceived discrimination, economic adversity, and other cultural and contextual domains that impact the lives of underserved diverse populations? In addition to providing a review of the articles included in this issue, recommendations are included for informing future prevention research according to equity perspectives.

Family Functioning in Hispanic Parents of Adolescents: Who Benefits Most from a Family-Based HIV and Substance Use Preventive Intervention?

To understand which families are likely to benefit most from resource-intensive family-based, evidence-based interventions (EBIs), we must examine the key, modifiable determinant of family functioning. The purpose of this study was to (1) identify whether there are subgroups of Hispanic parents that differ meaningfully based on their family functioning at baseline, (2) test whether the Familias Unidas preventive intervention was differentially effective across the baseline family functioning subgroups, and (3) understand the mechanisms of intervention effectiveness within each baseline family functioning subgroup. On a pooled data set of 4 completed efficacy and effectiveness trials of Familias Unidas (n = 1445 low-income, Hispanic immigrant origin, parents and their adolescent between the ages of 12-17), we conducted a series of secondary data analyses. Latent profile analyses revealed four significantly different profiles: (1) low family functioning (n = 210, 14.55%), (2) low-to-moderate family functioning (n = 554, 38.39%), (3) moderate-to-high family functioning (n = 490, 33.96%), and (4) high family functioning (n = 189, 13.10%). A structural equation modeling approach found there were significant differences in intervention effectiveness between the subgroups. The low family functioning subgroup experienced gains in family functioning, and in turn, lower levels of adolescent substance use, internalizing, and externalizing symptoms. The high family functioning subgroup showed significant direct effects of the intervention on adolescent substance use, internalizing, and externalizing symptoms, but no indirect effects through improvements in family functioning. Implications for screening, targeting, and adapting interventions are discussed.

A machine learning approach to improve implementation monitoring of family-based preventive interventions in primary care

Background

Evidence-based parenting programs effectively prevent the onset and escalation of child and adolescent behavioral health problems. When programs have been taken to scale, declines in the quality of implementation diminish intervention effects. Gold-standard methods of implementation monitoring are cost-prohibitive and impractical in resource-scarce delivery systems. Technological developments using computational linguistics and machine learning offer an opportunity to assess fidelity in a low burden, timely, and comprehensive manner.

Methods

In this study, we test two natural language processing (NLP) methods [i.e., Term Frequency-Inverse Document Frequency (TF-IDF) and Bidirectional Encoder Representations from Transformers (BERT)] to assess the delivery of the Family Check-Up 4 Health (FCU4Health) program in a type 2 hybrid effectiveness-implementation trial conducted in primary care settings that serve primarily Latino families. We trained and evaluated models using 116 English and 81 Spanish-language transcripts from the 113 families who initiated FCU4Health services. We evaluated the concurrent validity of the TF-IDF and BERT models using observer ratings of program sessions using the COACH measure of competent adherence. Following the Implementation Cascade model, we assessed predictive validity using multiple indicators of parent engagement, which have been demonstrated to predict improvements in parenting and child outcomes.

Results

Both TF-IDF and BERT ratings were significantly associated with observer ratings and engagement outcomes. Using mean squared error, results demonstrated improvement over baseline for observer ratings from a range of 0.83-1.02 to 0.62-0.76, resulting in an average improvement of 24%. Similarly, results demonstrated improvement over baseline for parent engagement indicators from a range of 0.81-27.3 to 0.62-19.50, resulting in an approximate average improvement of 18%.

Conclusions

These results demonstrate the potential for NLP methods to assess implementation in evidence-based parenting programs delivered at scale. Future directions are presented.

Taking a Motivational Interviewing Approach to Prevention Science: Progress and Extensions

This commentary reviews advances gleaned from the current set of papers to Motivational Interviewing (MI) in prevention science. We begin by acknowledging the pioneering work of Miller and Rollnick to develop the construct of MI, then Dishion's use of MI principles to adapt applications of MI for the field of prevention science. We then highlight some of the contributions provided by the current set of papers and other recent extensions of MI. These novel applications are directed to parents, teachers, and older youth in the service of facilitating behavior change to promote youth development.
