Family Functioning Affected by Adolescent Idiopathic Scoliosis in China: A Cross-Sectional Study

Adolescent idiopathic scoliosis (AIS) is a common chronic disease in youths, presenting with spinal deformity. Previous studies reported that the family functioning of family members would be affected after a child is diagnosed with a chronic health condition. However, no previous study focused on the relationship between AIS and family function. This study is a cross-sectional study that enrolled 54 AIS families and 92 ordinary families and evaluated their family function in 7 domains using the McMaster family assessment device (FAD). The results showed that the AIS family got a lower score than a healthy family in all 7 subscales except for the problem-solving subscale. There was no significant difference between the patients with AIS (1.90 ± 0.42∼2.23 ± 0.32) and their parents (1.92 ± 0.35∼2.21 ± 0.29) in all seven subscales (p ≥ 0.05). The scores of the parents were moderately/strongly correlated with those of the patients with AIS in all seven subscales (γ = 0.456∼0.696, p < 0.05). Approximately, 20.4–87% of the families experienced unhealthy family functioning, with affective involvement (57.4%), and behavior control (87%) representing the unhealthiest subscales with the mean scores above the cutoff. It can be concluded that the AIS family performed better than a healthy family in family functions.
