[Idiopathic and secondary Raynaud's phenomenon. A comparative psychosomatic approach].

Thirty subjects with Raynaud's phenomenon admitted for determination of its cause underwent psychological examination. Raynaud's phenomenon was regarded as primary in 14 cases, secondary (usually to scleroderma) in 13 cases and eluding classification in 3 cases. The mean age of patients with primary Raynaud's phenomenon was higher than in the other groups. Interviews and psychological tests were carried out with all but 2 patients and all investigators being totally unaware of the aetiological category. Patients with secondary Raynaud's phenomenon significantly differed from those with primary Raynaud's phenomenon in their personality patterns, attitudes towards interlocutors and way of coping with conflicts. Patients with primary Raynaud's phenomenon were characterized by a relatively frequent hysterical personality and by their dodging behaviour when faced with their own aggressiveness. Patients with secondary Raynaud's phenomenon were found to be more distant, more conformist, more able to control their emotions and seemed to be less inclined to seek help when in trouble. Such findings suggest that Raynaud's phenomenon has a "psychosomatic" component: a psychic vulnerability which might contribute to the progress of the disease, and more clearly so in patients with secondary Raynaud's phenomenon than in patients with primary Raynaud's phenomenon, as confirmed by the so-called psychic fragility" score used to quantify the efficiency of mental functioning. These psychological features were unrelated to age. The profile of patients with secondary Raynaud's phenomenon is close to pattern C described as possibly having a prognostic value in proliferative or autoimmune diseases.
