The contributors of emotional distress in painful diabetic neuropathy

Aims: To examine the contribution of demographic, social, clinical and psychological factors to emotional distress in patients with painful diabetic neuropathy (DN). Methods: In total, 142 patients with confirmed painful DN underwent detailed clinical and self-assessment measures (Neuropathic Pain Scale, Hospital Anxiety and Depression Scale, Pain Acceptance Questionnaire and Pain Catastrophizing Scale). Results: The prevalence of emotional distress was 51.4% in this cohort. Age, sex, marital status, employment history, pain intensity, duration of diabetes and the presence of diabetic and non-diabetic complications were significantly correlated to anxiety and depressive symptom scores. Multiple regression analysis confirmed that the presence of catastrophic thinking was an independent contributor to greater symptoms of anxiety and depression. Being young, single and unemployed significantly contributed to greater anxiety symptoms. Pain-related restriction of quality of life was associated with greater depression symptom scores. Conclusions: This study found a high prevalence of emotional distress in patients with painful DN. It highlights that the differing independent contributors to anxiety and depressive symptoms are based on an individual’s circumstances and experience. We conclude by highlighting the importance of adopting a holistic approach to pain management, incorporating interventions to increase psychological flexibility alongside conventional pharmacological treatments to improve emotional distress in painful DN.
