The aim of the study was to develop and to assess the psychometric properties of the Problematic Support Scale, among patients with systemic lupus erythematosus. An online questionnaire was filled in by 344 systemic lupus erythematosus patients with a mean age of 39.66 years. Explorative factor analysis, later validated by confirmative factor analysis, showed the emergence of a two-factor structure in types of support provided: denying/uninformed support and oppressive support. Denying/uninformed support includes offers of support that neglect the disease manifestations and consequences. Oppressive support describes social support offers which are perceived as excessive and oppressive. Results confirm previous qualitative evidence and demonstrate good reliability and concurrent validity of the Problematic Support Scale. Theoretical and methodological implications for the study of social support are discussed.
