The Arabic version of the HAD scale was validated in a sample of 50 Saudi patients. The scale scores were assessed against the principal author's clinical evaluations. Spearman correlations of all items of the scale, except for one, were statistically significant. The non-significance of one item was probably related to the way it was translated into Arabic. The study furnished evidence that the Arabic version was a reliable instrument for detecting states of anxiety and depression in Saudi patients in a primary health care setting.
