| Summary: | BackgroundThe increasing prevalence of pediatric atopic diseases in China poses substantial risks to children’s physical health, mental well-being, and quality of life. Cognitive behavioral interventions for caregivers are effective in managing pediatric atopic diseases. Existing interventions are typically siloed and lack integration across the comorbidities of the atopic march. The protection motivation theory (PMT) could provide an integrated cognitive behavioral intervention framework for addressing shared pathophysiological mechanisms and unifying management strategies across atopic diseases, while online interventions offer advantages in accessibility, cost-effectiveness, and scalability, particularly for caregiver-mediated pediatric care.
ObjectiveThis study aimed to develop and evaluate a PMT-based cognitive behavioral online (PMT-CBO) intervention for caregivers of children with atopic diseases, assessing its effects on caregivers’ protective motivation, behavioral intentions, preventive practices, and children’s atopic disease outcomes.
MethodsA quasi-experimental design was conducted in 3 health care institutions in Hangzhou, China, where 2 health care institutions were assigned to the PMT-CBO group (127/243, 52.3%) and 1 health care institution was assigned to the control group (116/243, 47.7%). Caregivers in the PMT-CBO group received a 4-week structured course comprising 16 online modules delivered via a WeChat mini-program, whereas controls received routine care with verbal education. Primary outcomes included caregivers’ PMT dimensions (threat appraisal and coping appraisal), behavioral intentions, and preventive behaviors, and secondary outcomes involved children’s symptom severity and medication adherence. The primary outcome scales or questionnaires were designed by the research team, while the secondary outcome scales were derived from established studies. All scales demonstrated good reliability and validity. Intention-to-treat analysis was used.
ResultsCompared to the control group, the PMT-CBO group demonstrated significant improvements in overall PMT scores (Z=–6.289; P<.001) and most subdimensions (response efficacy, self-efficacy, threat severity, and response cost, with P<.05), except susceptibility (Z=–1.321; P=.19) and reward appraisals (Z=–0.989; P=.32). In the intervention group, caregivers exhibited stronger intentions and partial behavioral optimization (eg, environmental allergen control, with Z=–3.025; P=.002) and children showed improved medication adherence (Z=–4.457; P<.001) and alleviated eczema (Z=–3.112; P=.002) and allergic rhinitis symptoms (Z=–3.277; P<.001), although no significant differences emerged in asthma control (Z=–.830; P=.41) or food allergy–related caregiver burden (Z=–1.693; P=.09).
ConclusionsThe PMT-CBO intervention enhanced caregivers’ motivation and intentions and children’s medication adherence and eczema and rhinitis outcomes, with a 91.3% (116/127) completion rate via WeChat’s scalable platform. Limited improvements in asthma control and food allergy management implied the future need for additional condition-specific plug-ins, beyond the core PMT-CBO modules. Moreover, merging this PMT-CBO intervention with implementation techniques or ecological frameworks could help address intention-behavior gaps and external barriers, thereby promoting equitable and precision-based allergy care. |
