The GCPS 2.0 is an eight-item scale that evaluates the severity of chronic pain, the presence of persistent pain due to pain days, and the degree of disability due to pain. It is easy, simple, useful and multidimensional. 80 volunteer participants who had chronic low back pain were studied.The data collection tools used in this study were; Clinic and Demographic Evaluation Form, Oswestry Low Back Pain Disability Index, Patterns of Activity Measure Pain, Roland-Morris Disability Questionnaire, Hospital Anxiety, and Depression Scale, and Graded Chronic Pain Scale 2.0. In this study, the forms were sent by e-mail. The Snowball sampling method was used in the data collection process.The stages of the Beaton Protocol were followed in the translation of the scale. Validity was evaluated with the Face, Content, and Construct validity analyses. Exploratory and confirmatory factor analyses were applied to determine the construct validity of the Turkish version of the scale. Reliability was evaluated with the test-retest method, the parallel forms method, and the internal consistency. Ten days after completing the scale, 30 participants filled out the scale again for the Test-retest method. One of the scales we used for the parallel forms method was RMDQ and the other was ODI.
This study was designed to conduct Turkish adaptation, cross-cultural adaptation, validity, and reliability study of Graded Chronic Pain Scale 2.0 in order to use it for Turkish people with Chronic Pain.
