Cerebral palsy (CP) is a non-progressive problem that occurs as a result of damage or lesion in the brain tissue in the prenatal, perinatal or postnatal periods for any reason, causing permanent impairment in the development of posture and movement. In addition to the impairments in the motor area in CP; It can be seen in problems such as perception, cognitive, sensory, communication, social, behavioral, musculoskeletal, epilepsy .Parents who are primary caregivers of the child with CP; They have a very important caregiver role in meeting the processes such as the treatment of the child, daily life needs and rehabilitation.Parental self-efficacy has been defined as the judgments and beliefs held by the parents to cope with the difficulties they experience in raising and caring for children with developmental disabilities and to reach the goal.The long process of caring for the child with cerebral palsy and the dependence of the child on the parent increase the stress of the caregivers. The Calgary Family Intervention Model (CAMM), one of the nursing models, is the first family intervention model in the field of nursing. The model focuses on improving, developing and maintaining the family's functionality in three areas. These three areas are cognitive, emotional and behavioral.

In addition to the disorders in the motor area in SP; It can be seen in problems such as perception, cognitive, sensory, communication, social, behavioral, musculoskeletal, epilepsy .

Parents who are primary caregivers of the child with CP; They have a very important caregiver role in meeting the processes such as the treatment of the child, daily life needs and rehabilitation . Meeting all these special needs of the child with CP creates the burden of care for the parents .

Parental self-efficacy has been defined as the judgments and beliefs held by the parents to cope with the difficulties they experience in raising and caring for children with developmental disabilities and to reach the goal . People with high parental self-efficacy; It has been stated that they are more self-confident in taking and fulfilling their parenting duties, they make more effort, and they focus more on a solution in the face of any problem. The long process of caring for the child with cerebral palsy and the dependence of the child on the parent increase the stress of the caregivers. Caregiving stress affects the physiological, psychological, economic and social behaviors of parents.

The Calgary Family Intervention Model, one of the nursing models, is the first family intervention model in the field of nursing. The model focuses on improving, developing and maintaining the family's functionality in three areas. These three areas are cognitive, emotional and behavioral. The Calgary Family Intervention Model is an important model in increasing family functionality and providing change in pediatric nursing practice .

In the literature review, no other study has been found yet, examining the effect of motivational interviewing based on the Calgary Family Intervention model on the burden of care, self-efficacy and coping with stress in parents of children with cerebral palsy. It is believed that the motivational interview technique to be applied to the parents can be more beneficial for the children they care for and themselves, by revealing the effects of the disease, the responsibilities brought by the disease, the care burden arising from these responsibilities, parent self-efficacy and coping with stress.
