About this study

Official title: Reliability and Validity of the Turkish Version of the Pain Modulation Index

In order to assess the validity and reliability of the Turkish version of Pain Modulation Index, 125 volunteers with chronic pain were enrolled in the study. Test and re-test method was used to assess reliability and correlation analyses with Pain Detect, visual analog scale pain and central sensitization inventory scores were used to assess validity of the questionnaire. Turkish version of the Pain Modulation Index was found to be a valid and reliable tool for evaluating chronic pain.

Read the detailed description

Pain Modulation Index is a questionnaire that was developed in English for the assessment of chronic pain for qualities consistent with central sensitization. The English version of the questionnaire was translated into Turkish by two physicians than back translated into English by two separate bilingual translators. Initially 10 volunteers were asked to answer this first version of the questionnaire and report any difficulties in understanding the items. Their feedback was used to give the questionnaire its final shape. For the validation stage, patients that were diagnosed as having chronic non-cancer pain with more than 3 months duration were enrolled into the study. They answered the questions twice, 15 days apart. In addition to the Turkish version of the Pain Modulation Index, on the first visit, they were also asked to answer Pain Detect and Central Sensitization Inventory. Their answers were analysed to assess the validity and reliability of the Turkish version of Pain Modulation Index.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pain Modulation IndexDiagnostic test

    A 18 item questionnaire assessing patients' pain characteristics for the detection of disordered pain modulation processes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Reliability of the Turkish version of pain modulation index

    Internal consistency was evaluated by test retest method and calculating the coefficient alpha (α) or Cronbach's coefficient, and if the Cronbach's coefficient value was greater than 0.7, it was considered as an acceptable internal consistency

    Measured: 15 days

  2. Validity of the Turkish version of Pain Modulation Index

    Index scores were analysed for their correlation with Pain Detect and Central Sensitization Inventory scores.

    Measured: 1 day

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reliability of the Turkish version of pain modulation index (time frame: 15 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05698069, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2023.
