Single-case experimental design reduced maternal depressive symptoms in mothers of cystic fibrosis patients, highlighting the need for longer interventions.
Cystic fibrosis is usually diagnosed in early childhood, affecting primary caregivers’ mental health and interaction with the child. This study evaluated the effects of a problem-solving skills training on maternal depressive symptoms and control strategies with the child (appropriate support, critical control, and overprotection) in two mothers of children with cystic fibrosis. We conducted a pilot AB single-case experimental design. In baseline and post-intervention evaluations, mothers answered the Beck Depression Inventory-II and the Semi-Structured Interview on Maternal Control. The results showed a decrease in maternal depressive symptoms in both cases. Appropriate support slightly increased, and there was a modest decrease in overprotection in one case. The problem-solving skills training reduces symptoms of depression in mothers of children with cystic fibrosis by promoting effective solutions to everyday demands with children. However, it is necessary to extend the program’s strategies or duration to produce relevant effects on maternal control.
