摘要:Aim This study aimed to analyse the possible differences regarding the relation between emotional variables (anxiety and depression), pain and the rest of fibromyalgia parameters according to nationality. Methods. We included 128 patients (64 from each country, respectivelly Romania and Spain) and we evaluated socio-demographic, diagnosis and clinical parameters by means of: clinical history, interview, observation, self-report questionnaires and pressure pain thresholds (algometry). Results. We observed that the nationality of the patients influenced the relation between experienced pain or associated symptoms and anxiety or depression. This relationship is more significant for the Romanian sample while for the Spanish patients the parameters are more independent. Conclusion. Cultural differences have to be considered when establishing which symptoms are inherent to the diagnosis of FM and which of them come as consequences, in order to enable a better diagnosis and provide a more effective treatment for this condition.
