RESUMEN
Disparities in care for low-income children of color call for innovative culturally and linguistically responsive solutions to better engage marginalized populations in evidence-based interventions. In partnership with a community organization, the addition of natural helper support as an adjunct to Parent-Child Interaction Therapy (PCIT+NH) was examined as a strategy to increase recruitment, engagement, and retention in PCIT for families historically unreached by a university-based clinic. Natural helpers provided home-based skills practice and support for forty-two families whose parents were more racially and linguistically diverse and had lower income and lower caregiver education than the typical population served by the same program (i.e., program population). Families who received PCIT+NH had comparable or higher rates of engagement and improvements in clinical outcomes (i.e., decreased child externalizing and internalizing behaviors, increased child compliance, decreased caregiver stress, increased caregiver parenting skills) relative to the program population. Furthermore, higher doses of natural helper support were associated with higher rates on most measures of treatment engagement (i.e., treatment completion, completion of the Child Directed Interaction phase of treatment, PCIT sessions, homework in the Parent Directed Interaction phase of treatment), with the exception of homework in the Child Directed Interaction phase of treatment and overall session attendance rate. Next steps for testing the treatment engagement and clinical outcome effects of the PCIT+NH model are discussed.
RESUMEN
BACKGROUND: Since the risk of noncommunicable diseases is closely associated with dietary intake, it is important to establish healthy dietary habits in childhood. Although several dietary education programs for children have been attempted, their implementation at school was often difficult due to overcrowded study curricula. We developed a new program which included homework for children and guardians, and evaluated its effect. Determinants of the effect were also investigated. METHODS: The school-based nutrition education program including a 45-min lecture, a series of homework assignments involving children and guardians, and two handouts was implemented in 14 public primary schools in Japan. Seven schools each underwent the intervention in an alternating manner. Nutrition knowledge (percentage (%) of correct answers in the nutrition knowledge questionnaire) and attitude/behavior toward diet was evaluated three times (May (baseline), October, February) as outcomes. These factors and their changes following the intervention were assessed by linear mixed models to adjust for individual factors, with consideration to clustering of the participants and repeated measurements. RESULTS: In total, 2227 children aged 10-12 years and their guardians participated. All schools completed the program. Children's nutrition knowledge level was significantly increased (8.7%, 95% confidence interval [7.7-9.7]) following the intervention. Communication between children and their guardians, which was positively related with nutrition knowledge, was facilitated by the intervention. The increase in nutrition knowledge was greater among children with a lower knowledge level at baseline. CONCLUSIONS: This school-based nutrition education program was effective and feasible. Appropriate teaching materials for homework can reduce the burden on schools and facilitate communication between children and guardians. Public schools can be crucial venues for decreasing disparities in nutrition knowledge. TRIAL REGISTRATION: This study was registered as an intervention study in the UMIN Clinical Trials Registry (trial ID: UMIN000029252 ) on Sep 22, 2017.
