About this study

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.

Other

Data collection tools used in the study;

  • Clinic and Demographic Evaluation Form
  • Oswestry Low Back Pain Disability Index (ODI)
  • Patterns of Activity Measure Pain (POAM-P)
  • Roland-Morris Disability Questionnaire (RMDQ)
  • Hospital Anxiety and Depression Scale (HADS)
  • Graded Chronic Pain Scale Version 2.0 (GCPS 2.0)

Primary outcomes

  1. Graded Chronic Pain Scale 2.0

    Time frame: 3 minutes

    GCPS 2.0 measures multiple dimensions of pain in patients with chronic pain.

  2. Clinic and Demographic Evaluation Form

    Time frame: 5 minutes

    n the clinical section, there are questions the inclusion and exclusion criteria. According to this section, the patient is included in the study. In the demographic section, there is the section where the patient's demographic variables are collected.

  3. Oswestry Low Back Pain Disability Index (ODI)

    Time frame: 5 minutes

    ODI is a questionnaire measuring the effect of low back pain on daily life and the level of disability caused by this pain.

  4. Roland-Morris Disability Questionnaire (RMDQ)

    Time frame: 5 minutes

    RMDQ is a sensitive tool that measures the loss of function and disability due to low back pain.

Secondary outcomes

  1. Hospital Anxiety and Depression Scale (HADS)

    Time frame: 5 minutes

    The hospital anxiety and depression scale have two sub-scales: Anxiety and Depression. 7 single-digit questions in the scale measure anxiety, while 7 questions with two numbers measure depression.

  2. Patterns of Activity Measure Pain (POAM-P)

    Time frame: 15 minutes

    Some established activity patterns reduce patients' quality of life with chronic pain, increase their pain, and limit their movement. These are modified patterns such as Overdoing, Avoidance, Pacing. POAM-P determines which of these patterns chronic pain patients use. There are 10 questions in each subsection, also 30 questions in total.
