December 6, 2017 updated by: Chin Yi Zhe, University of Malaya

Validation Study of the Malay Version of the 3-Minute Diagnostic Interview for Confusion Assessment Method Defined Delirium (3D-CAM)

Validation of the Malay version of 3D-CAM, involving two-staged process.

  1. Translation and cultural adaptation of 3D-CAM into the Malay language.
  2. Testing for Validity and Reliability of the translated 3D-CAM tool to detect postoperative delirium.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  1. Translation and Cultural Adaptation

    The research panel, who consisted of experts in the clinical field of anesthesia, did the meticulous process of translation and cultural adaptation of 3D-CAM.

    This process included independent translation by the research panel, reconciliation of two independent translated 3D-CAM, ethics approval prior to pilot study on 20 relevant subjects, back translation into English and finalizing the Malay version of 3D-CAM for the next phase of testing.

  2. Testing for Validity and Reliability of the translated 3D-CAM tool

Patients were recruited pre-operatively after reading the patient's information sheet and signing the informed consent.

Post-operatively, two trained assessors separately administered the Malay 3D-CAM on the recruited patients. One of the trained assessors administered the original 3D-CAM on the same patients at a different time. Standard reference of diagnosing delirium was made by a psychiatrist using the DSM V criteria, after interviewing the patients.

  1. For validity, the diagnosis of delirium made using the Malay 3D-CAM tool was tested against the standard reference for diagnosing delirium according to the DSM V criteria made by a psychiatrist
  2. For inter-rater reliability, the diagnosis of delirium made by two trained assessors using the Malay 3D-CAM tool were statistically compared.
  3. For parallel reliability, the diagnosis of delirium made using the Malay 3D-CAM was compared to the original English version of 3D-CAM.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
