The study evaluates the psychometric properties of a Polish translation of the Brief Illness Perception Questionnaire. A total of 276 patients with chronic conditions (58.7% women) completed the Brief Illness Perception Questionnaire and the Hospital Anxiety and Depression Scale. The internal consistency of the Polish Brief Illness Perception Questionnaire measured with Cronbach's alpha was satisfactory (α = 0.74). Structural validity was demonstrated by significant inter-correlations between the Brief Illness Perception Questionnaire components. Discriminant validity was supported by the fact that the Brief Illness Perception Questionnaire enables patients with various conditions to be differentiated. Significant correlations were found between Brief Illness Perception Questionnaire and depression and anxiety levels. The Polish Brief Illness Perception Questionnaire thus evaluated is a reliable and valid tool.

Objectives Illness perception is a cognitive representation influencing physical and psychological functioning and adherence in patients with rheumatic disease. Studies exploring illness perception in systemic lupus erythematosus (SLE) are still scarce and none of them have investigated factors determining illness perception. We aimed to assess illness perception and to identify psychological, clinical and sociodemographic factors that might influence illness perception in SLE. Methods The study involved 80 patients with SLE (87.5% women, mean age 41.56 years). The Brief Illness Perception Questionnaire, State Trait Anxiety Inventory, Beck Depression Inventory, Pittsburgh Sleep Quality Index, Visual Analogue Scale-Pain and Fatigue Severity Scale were used. Clinical and sociodemographic data were collected via structured interview and medical files review. Results Illness perception was significantly positively correlated with anxiety, depression, sleep quality, fatigue and pain while it was not related to age, education, steroid treatment, disease duration and activity (SLEDAI) or organ damage (SLICC/ACR). Regression analysis revealed that state anxiety and depression explained 43% of illness perception variance. Cluster analysis identified three patient groups among which the middle-aged group had the most negative illness perception, the highest levels of anxiety, depression, pain and fatigue, and the poorest sleep quality. Conclusions The study has proved a significant relationship between negative illness perception and anxiety and depression. Patients reporting fatigue, poor sleep and pain might have special needs in terms of psychological intervention focused on negative illness perception and distress symptoms. Multidisciplinary care in managing SLE seems to be of great importance.

Objectives Sjögren's syndrome (SS) is a chronic inflammatory disease with an autoimmune background with possible complications from peripheral (PNS) and central nervous system (CNS). The aim of this study was to assess the prevalence and to describe the phenotype of peripheral neuropathies in patients with SS. Materials & Methods We studied fifty patients with primary Sjögren's syndrome for peripheral nervous system involvement. All patients underwent neurological and rheumatological examination followed by nerve conduction studies (NCS) of nine peripheral nerves. Results Thirty‐six patients (72%) fulfilled the criteria for the diagnosis of neuropathy. Carpal tunnel syndrome (54%) and axonal sensorimotor neuropathy (22%) were the most common. Neurological symptoms preceded the diagnosis of SS in eight patients. Conclusions Peripheral neuropathies are frequent in SS patients. Neurologists should be aware of possible autoimmune causes of neuropathies because clinical manifestations of neuropathy may precede the development of other symptoms of the autoimmune disease.
