RESUMEN
AIM: To delineate the impact of perspective of children's transition readiness from paediatric to adult health care on quality of life in child-parent dyads with long-term conditions. We used Actor-Partner Interdependence Model to identify actor effects (effect of one's own transition readiness on one's own quality of life) and partner effects (effect of one's own transition readiness on the partner's quality of life). DESIGN: A multi-centre cross-sectional survey. METHODS: The study was conducted in two paediatric hospitals in China from October 2018-August 2019. We used a researcher-designed questionnaire to collect demographic and clinical characteristics. Furthermore, we used four questionnaires assessing transition readiness and quality of life in child and parent respectively to collect data from 370 child-parent dyads. Structural equation modelling was applied to estimate the effect of actor-partner interdependence models. RESULTS: The total score of transition readiness had two actor effects on total child and parent quality of life controlling for age (ßchildren = 3.335, p = .032 and ßparents = 8.952, p < .001), while only one actor effect controlling for gender (ßparents = 8.891, p < .001). Specific transition readiness dimensions had different partner effects on different domains of children and parents' quality of life. Moreover, younger children and fathers had a better quality of life. CONCLUSION: Our study verified inherently interpersonal relationship that transition readiness appeared to influence quality of life in child-parent dyads with long-term conditions. IMPACT: This study was the first to verify mutual influence of transition readiness and quality of life in child-parent dyad using actor-partner interdependence model. Nurses who design the transition promoting programs should consider the effective communication between healthcare provider and child-parent dyads and support parents' involvement to improve shared understanding about managing child's condition, especially for older children and mothers.
