Abstract
There are many causes of dizziness, one of them is vertigo that creates a false
spinning sensation either for the surrounding or self-rotation. It is a common clinical
syndrome. The concurrence of the dizziness and psychiatric illness can affect the
treatment efficacy and rehabilitation. Screening for psychological symptoms mainly
anxiety and depression in dizzy patients is important for proper assessment and treatment.
The hospital anxiety and depression scale (HADS) is a questionnaire designed by
Zigmond and Snaith (42) to provide an accurate method for use in clinical practice to
screen anxiety and depression symptoms. It is a 14-item scale composed of two
subscales; anxiety subscale and depression subscale, and each had seven items. It should
not be used alone to make a clinical diagnosis, but only to indicate the probability of a
psychiatric disorder being present.
Accordingly, the aim of the current study is to develop and adapt an Arabic
version of HADS. It was translated following cross-cultural adaptation guidelines. The
study sample consisted of 100 normal controls (control group), 30 patients complaining
of anxiety (anxiety group), 30 patients complaining of depression (depression group);
anxiety and depression were diagnosed according to diagnostic and statistical manual of
mental illness fifth edition (DSM-5), and 100 patients complaining of dizziness (dizzy
group). Patients with disturbed consciousness and severe mental health disorders were
excluded. The patients completed the HADS then; retest was done after one hour.
Reliability including internal consistency and test retest reliability and Validity including
content and construct validity were examined. Receiver operating characteristic (ROC)
curve was used to determine the possible cut off points. The prevalence of anxiety and
depression in dizzy patients was determined.
The Arabic HADS showed good internal consistency (Cronbach’s alpha=0.806
for controls, 0.811 for anxiety group and =0.758 for depression group). Test-retest
correlation for repeatability was high (r =0.980 among anxiety cases and 0.928 among
depression cases). Regarding the construct validity; the mean values of the total scores
were significantly higher in anxiety and depression patients than controls. For the anxiety
subscale, the mean total score was 8.71 ± 4.21 for the control group, 12.06 ± 3.55 for
anxiety group, and 12.86 ± 3.35 for the depression groups. Also, P value was less than
0.001 indicating validity of Arabic HADS. The prevalence of anxiety in dizzy patients
was 32% and the prevalence of depression was 22%.
