Background and Objectives: Anxiety disorders are common in individuals with diabetes mellitus (DM) and have a negative impact on diabetes-related self-management and, therefore, on patients’ evolution and prognosis. In this context, it becomes necessary to accurately and easily assess anxiety and self-management behaviours. Thus, the aim of this research was translation and cultural adaptation for Romanian patients and validation of two instruments used for assessing diabetes self-management and anxiety, namely the Diabetes Self-Management Questionnaire (DSMQ) and the Social Phobia Inventory (SPIN). Materials and Methods: The Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) and the DSMQ instruments for assessing diabetes self-management, as well as the Generalised Anxiety Disorder Scale (GAD-7) and the SPIN instruments for assessing anxiety, have been administered to 117 patients from Timisoara, Romania, previously diagnosed with DM. Results: The SPIN has proven to have good internal consistency, excellent acceptability of its questions without non-responders and a median completion time of 3 min and 10 s, an excellent test−retest performance (Spearman’s rho = 0.971, p < 0.001 between two administrations of the test) and good validity in comparison with the GAD-7, a previously validated and comprehensive instrument. The DSMQ has also proven to have acceptable internal consistency, excellent acceptability of its questions without non-responders and a median completion time of 2 min and 28 s; however, it has shown a weak, positive correlation without statistical significance in comparison with the SDSCA, a previously validated questionnaire. Conclusions: The SPIN, translated in Romanian and culturally adapted, is a valid tool for the screening of social phobias in individuals with DM. The DSMQ requires additional data for its validation in DM patients from Romania.
