The purpose of this study is to translate and culturally adapt the quality of life profile for spinal deformities (QLPSD) to Turkish language and test the validity and reliability of Turkish version of QLPSD in patients with adolescent idiopathic scoliosis.


The QLPSD, developed in Spain, was the first questionnaire designed to evaluate HRQoL in adolescents with spinal deformities. It contains 21 items in five dimensions: psychosocial functioning (7 items), sleep disturbances (4 items), back pain (3 items), body image (4 items), and back flexibility (3 items). Responses to items use a 5-point Likert scale. The possible score range is 21-105.

The QLPSD has shown good validity and reliability. English, French and Persian versions of the QLPSD have been developed and validated. Good reliability and ease of use are mentioned in these versions. The QLPSD was designed to examine adolescents with spinal deformities and measure the effect of orthotic and surgical treatments on QoL. This questionnaire is practical and suitable for patients with spinal deformities. As a result we choose to translate the QLPSD into Turkish as it is less costly, practical and time consuming than developing a new tool. QLPSD may be preferred during follow-up of the results of conservative and / or surgical treatments for spinal deformities.
