The challenge of pet therapy in systemic sclerosis: evidence for an impact on pain, anxiety, neuroticism and social interaction.

Objectives: The aim of our study was to evaluate the effect of animal-assisted intervention (AAI), a complementary support to traditional therapies focused on the interaction between animals and human beings, in improving psychological trait, anxiety and pain in a cohort of systemic sclerosis (SSc) patients.

Methods: 42 SSc patients, undergoing iloprost intravenous infusion, were divided in three groups: 1) 14 patients submitted to 20 AAI sessions; 2) 14 patients engaged in alternative social activity (control group 1 - C1); and 3) 14 patients without any alternative activity (control group 2 - C2). All patients underwent Visual Analog Scale (VAS), the State-anxiety (STAI-S) and emotional faces at the beginning (s0) and at the end (s1) of each single session, while General Anxiety State-Trait Anxiety Inventory (STAI-T), Beck Depression Inventory (BDI), Social Interaction Anxiety Scale (SIAS), Eysenck Personality Questionnaire-Revised (EPQ-R), the Social Phobia Scale (SPS), the Toronto Alexythymia Scale (TAS-20), the Thought Control Questionnaire (TCQ) were administered at baseline (t0) and at the end of the project (t1).
