Living in the shadows: Correlational analysis of behavioral trajectories and quality of life among siblings of children with neurodevelopmental disorders.

BACKGROUND

Siblings of children with neurodevelopmental disorders (NDDs) often experience emotional neglect, caregiving burdens, and psychosocial stress, which compromise their quality of life (QoL) and increase vulnerability to long-term psychological strain.

OBJECTIVE

To examine the relationship between behavioral trajectories and quality of life among siblings of children with neurodevelopmental disorders.

METHODS

A descriptive correlational study design was employed with 200 parents of children diagnosis with NDDs and at least one sibling was recruited from pediatric hospitals. Data were collected using Socio-Demographic Interview Form, the Sibling Inventory of Behavior, and the Pediatric Quality of Life Inventory.

RESULTS

Siblings of children with NDD exhibited both positive behaviors (e.g., empathy, companionship) and negative behaviors (e.g., rivalry, aggression). Positive sibling behaviors were linked to better QoL, while negative behaviors correlated with poorer functioning. Regression analysis showed that educational level of the child with NDDs and sibling behavioral trajectories predicted QoL (R2 = 0.286, p < .001). Parental education, age, and family income were also influential factors.

CONCLUSION

Siblings of children with neurodevelopmental disorders are vulnerable to psychological strain, with their QoL directly impacted by sibling dynamics and socio-demographic variables. While positive interactions offer some protective value, they alone cannot offset the broader burdens imposed by living in high-demand caregiving environments.

NURSING IMPLICATIONS: Nurses and allied health professionals should adopt family-centered approaches that integrate tailored psychosocial support programs for siblings of children with NDD. Support programs should focus on resilience-building, coping strategies, and inclusive family communication to mitigate emotional strain and enhance QoL.
