A personalized and control systems engineering conceptual approach to target childhood anxiety in the contexts of cultural diversity

Person-Centered Cultural Assessment Can Improve Child Mental Health Service Engagement and Outcomes

OBJECTIVE

Disparities in child mental health service engagement suggest traditional evidence-based practices do not properly consider cultural and contextual factors relevant for marginalized families. We propose a person-centered approach to improve the cultural responsiveness of services. Preliminary research supports broadening standard assessments to include a person-centered evaluation of patient cultural factors, however, controlled studies have not been conducted in the context of children's mental health care.

METHODS

Participants included families (N = 89; 89% racial/ethnic minority) receiving services for child externalizing problems. Prior to intake, caregivers were randomized to receive either Assessment as Usual (AAU) or AAU augmented with the Cultural Formulation Interview (CFI+AAU), a brief caregiver assessment of cultural factors affecting their child's problems and family help-seeking.

RESULTS

Implementation data showed strong provider fidelity and clinical utility. Following assessments, CFI+AAU caregivers (relative to AAU caregivers) reported feeling better understood by their provider, and providers reported better understanding CFI+AAU families' values. Caregiver satisfaction was rated highly overall, yet providers reported being more satisfied with the assessment when the CFI was incorporated. Engagement outcomes found CFI+AAU families were significantly more likely than AAU families to subsequently complete the first phase of treatment. Further, among families receiving services in Spanish, CFI+AAU, relative to AAU, was associated with significantly higher treatment attendance, homework completion, and treatment response.

CONCLUSIONS

The results underscore the utility of incorporating a brief cultural assessment in pretreatment assessments. To improve the cultural responsiveness of services, efforts may do well to promote the uptake of person-centered approaches such as cultural assessment into usual care.

A control systems engineering approach for adaptive behavioral interventions: illustration with a fibromyalgia intervention

The term adaptive intervention has been used in behavioral medicine to describe operationalized and individually tailored strategies for prevention and treatment of chronic, relapsing disorders. Control systems engineering offers an attractive means for designing and implementing adaptive behavioral interventions that feature intensive measurement and frequent decision-making over time. This is illustrated in this paper for the case of a low-dose naltrexone treatment intervention for fibromyalgia. System identification methods from engineering are used to estimate dynamical models from daily diary reports completed by participants. These dynamical models then form part of a model predictive control algorithm which systematically decides on treatment dosages based on measurements obtained under real-life conditions involving noise, disturbances, and uncertainty. The effectiveness and implications of this approach for behavioral interventions (in general) and pain treatment (in particular) are demonstrated using informative simulations.
