Objective: Although multidimensional interventions including physiotherapy, psychology, and education are generally recommended in managing headache, and to prevent chronification, such approach is lacking in cervicogenic headache (CeH). Therefore, exploring CeH within a biopsychosocial framework is deemed an essential first step. Methods: Non‐randomized cross‐sectional design to compare pain processing, lifestyle, and psychosocial characteristics between 18 participants with CeH (CeH group) (40.2 ± 10.9 years) and 18 matched controls (control group) (39.2 ± 13.1 years). Pain processing characteristics included degree of central sensitization (Central Sensitization Inventory), and (extra)‐cephalic pressure pain thresholds (kPa/cm²/s). Lifestyle characteristics included sleep quality (Pittsburgh Sleep Quality Index), physical activity, screen time, and sedentary time (hours a week). Psychosocial characteristics included degree of depression, anxiety and stress (Depression Anxiety Stress Scale‐21), and quality of life (Headache Impact Test‐6). Results: Pain processing characteristics: More (p =.04) participants in the CeH group showed higher degrees of central sensitization compared to the control group. Lower (p <.05) (extra)‐cephalic pressure pain thresholds were revealed in the CeH group compared to the control group for each muscle. Lifestyle and psychosocial characteristics: Compared to the control group, sleep quality and headache‐related quality of life were worse (p <.0001) in the CeH group. Severe to extreme stress was experienced by more participants in the CeH group (p =.02). Further, significant relations between pain processing and (1) lifestyle characteristics and (2) psychosocial characteristics were seen in the CeH group. Conclusion: Exploring multidimensional characteristics in CeH exposed relations between pain processing, lifestyle, and psychosocial characteristics. These novel findings fill a gap in the current scientific literature, and highlight the need for outcome research targeting lifestyle and psychosocial factors. Cervicogenic headache is a complex headache disorder. Pain processing, lifestyle, and psychosocial characteristics interact in patients with cervicogenic headache. [ABSTRACT FROM AUTHOR]
