| Abstract |
Introduction: “Dizziness” is a common complaint in clinical practice that can occur with anyone. However, since symptom is caused by a wide range of disorders, a general clinician is usually faced with some difficulty to detect its cause.
Objective: This study aimed to formulate and validate a simple instrument that can be used to screen and predict the most likely cause of dizziness in Thai outpatients.
Methods: This study was divided into two phases. Phase I was to determine the algorithm by using 41 patients who were diagnosed with common cause of dizziness, then construct the structural algorithm questionnaire version 1 (SAQ-1) and to test and retest its content validity and reliability until the instrument had an acceptable level of both. Phase II of the study pertained to evaluating its accuracy in clinical trials, 150 patients with dizziness had a face-to-face interviews while they were waiting to see the doctor.
Results: The degree of agreement between the algorithm results and clinical diagnoses was within an acceptable level (κ = 0.69). Therefore, this algorithm was used to construct the SAQ-1. The content validity of the SAQ-1was evaluated by seven experts. The content validity index values of the SAQ-1 ranged from 0.71 to 1.0. The Cohen’s kappa coefficient (κ) of intrarater reliability of the SAQ-1was 0.71. In clinical trials, 150 patients with dizziness had a face-to-face interviews while they were waiting to see the doctor. The overall agreement between their questionnaire responses and final diagnoses by specialists showed a moderate degree of clinical accuracy (κ = 0.55).
Conclusions: The SAQ-1 had a well-developed design and acceptable quality pertaining to both validity and reliability. It might be used to differentiate the cause of dizziness between vestibular and non-vestibular disorders, especially of outpatients with dizziness symptoms.
