The role of parenting stress and perceived social support in affecting family function among families of patients with cleft lip and/or palate: a path analysis based on the family adjustment and adaptation response model.

OBJECTIVES: Family function is important for the normal operation of the family and the development of children. However, existing studies have limited explorations on family function among families of patients with cleft lip and/or palate (CL/P). This study aims to validate a hypothesized model of family function based on the family adjustment and adaptation response model, and identify key variables affecting family function among families of patients with cleft lip and/or palate (CL/P) in China. MATERIALS AND METHODS: The cross-sectional study enrolled 248 families with CL/P patients from two centers in China. The demographic, clinical, family function, resilience, hope, perceived social support, optimism, parenting stress, and coping data were collected. Path analysis was used to investigate the key variables of the family function. RESULTS: Family functions among families of CL/P patients were higher than the Chinese norm in conflict, moral-religious-emphasis, and control. Furthermore, they were lower in expressiveness, independence, achievement orientation, intellectual, cultural orientation, active recreational orientation, and organization. The fitness of the modified path model was evaluated using various measures, including CMIN/DF = 1.954, GFI = 0.914, RFI = 0.801; IFI = 0.919;TLI = 0.909; CFI = 0.917; RMSEA = 0.065. The path analysis showed that perceived social support and parenting stress have a direct positive effect (β = 0.186) and negative effect (β = -0.384), respectively. Hope, optimism, perceived social support, coping, and resilience indirectly affect family function. The effects from highest to lowest are hope (β = 0.260), optimism (β = 0.203), perceived social support (β = 0.085), coping (β = 0.055), and resilience (β = 0.009). The overall effects of different variables on the family function are as follows: parenting stress (β = -0.384), perceived social support (β = 0.271), hope (β = 0.260), optimism (β = 0.203), coping (β = 0.055), and resilience (β = 0.009). CONCLUSIONS: The family functions of families with CL/P patients are worthy of attention in China. This study showed that parenting stress and perceived social support are key factors that directly affect family function. Coping, hope, resilience, and optimism could indirectly affect family function through parenting stress and perceived social support. Therefore, strategies targeting these two key factors should be implemented to facilitate family function among families with CL/P patients.
