Affective spectrum symptoms and self-criticism: A behavioral genetic approach

Studies have shown that depression and so-called functional somatic symptoms (FSS; i.e., chronic pain and fatigue) are highly comorbid both at the symptom [1,2] and syndrome [3 –8] level. In addition, there is evidence for familial co-aggregation at both the symptom and syndrome levels [9–12]. These findings have led researchers to suggest that functional somatic disorders and depression are part of an affective spectrum of symptoms and disorders [10,13], although it i s not clear whether a common pathophysiology and similar causal pathways are implicated in disorders belonging to this spectrum [14–19].
