Shame, anger and worry were among the most common problems detected in a study of 936 patients by a team in Italy.
Many patients could benefit from psychological care alongside psoriasis treatment, the researchers suggested.
The study authors used the Skindex-29 questionnaire to screen for psychosocial burden among patients with the condition. They found that anxiety and annoyance were more common in women than men, and were linked to lower levels of education. Patients also reported that their social and working lives were often impeded by the disease.
The researchers said clinicians should 'pay particular attention to these psychosocial aspects in the evaluation of psoriasis patients'.
They added that these patients may require particular clinical attention as a result, and could benefit from psychological care before and during psoriasis treatment.
