Correlations between scores on the HAD scale, and scores on the SF-36 subscales and reported number of somatic symptoms (n=300)

		No of somatic symptoms		SF-36		HAD total score		HAD depression score	HAD anxiety score
		No of somatic symptoms		Physical function	Physical role function	HAD total score		HAD depression score	HAD anxiety score	Bodily pain	Social function
HAD total score	0.5	−0.3	−0.4	−0.4	−0.6	—	0.8	0.9
HAD depression score	0.4	−0.5	−0.4	−0.4	−0.5	0.8	—	0.6
HAD anxiety score	0.4	−0.2	−0.2	−0.3	−0.4	0.9	0.6	—

All the correlations were statistically significant (p<0.0005, two tailed).
In the SF36 lower scores indicate increased disability or pain, hence the negative correlations between HAD and SF36 scores.
