To investigate the validity and clinical utility of distinguishing between DSM-5 somatic symptom disorder (SSD) and illness anxiety disorder (IAD) in pathological health anxiety: the excessive and recurrent fear of, or preoccupation with, having or developing a serious health condition. We compared SSD to IAD in pathological health anxiety (N = 334) with regard to concurrent, antecedent, and predictive validators. This was primarily a cross-sectional study, though we studied the effect of CBT longitudinally. Because we were interested in the discriminatory value of SSD and IAD over and above trait health anxiety, we used trait health anxiety as a covariate. SSD (68%; 228/334) vs. IAD (32%; 106/334) differences were mostly non-significant and small in sociodemographics, core clinical characteristics, apparent course, etiological attribution, and physician visits (gs = −0.18–0.20; RRs = 0.84–1.09; IRRs = 0.87–0.99). However, SSD was associated with a significantly higher somatic symptom burden (gs = 0.20–0.72), more psychologist visits (IRR = 2.02, 95% CI: 1.24–3.28), and slightly higher disability (g = 0.22, 95% CI: 0.03–0.42). There was no significant difference in symptom reduction during CBT (g = −0.16, 95% CI: −0.37-0.05). Although not all differences between SSD and IAD in pathological health anxiety seem to be explained by the level of trait health anxiety, the SSD vs. IAD distinction appears to convey little useful information in pathological health anxiety. Tentatively, considering the well-documented clinical characteristics and effective clinical interventions, it is probably most helpful to regard pathological health anxiety as a de facto anxiety or perhaps obsessive-compulsive spectrum disorder, regardless of the DSM-5 diagnosis of SSD or IAD. •Trait health anxiety can become pathological if recurrent and excessive.•Patients may meet criteria for DSM-5 somatic symptom disorder or illness anxiety disorder.•We investigated the validity and clinical utility of this diagnostic distinction.•Most validators were similar, including the response to cognitive behavior therapy.•This diagnostic distinction has questionable utility in pathological health anxiety.
