Knowledge, attitude, and practice of patients with major depressive disorder on exercise therapy

Background This study aimed to explore the knowledge, attitude, and practice (KAP) toward exercise therapy of patients with major depressive disorder (MDD). Methods This cross-sectional study was conducted at the First Hospital of Shanxi Medical University between April and October 2023 in patients with MDD. A self-designed questionnaire was used to evaluate the KAP (Cronbach’s α = 0.787). The minimum-maximum scores were 2–23 for knowledge, 11–55 for attitude, and 7–35 for practice. Results A total of 494 valid questionnaires were analyzed. The mean KAP dimension scores were 15.39 ± 3.34/23 (66.91%), 36.54 ± 19.33/55 (66.44%), and 19.33 ± 5.22/35 (55.23%), indicating poor knowledge, negative attitude, and weak practice. Multivariable logistic regression analysis showed that female (OR = 0.613, 95%CI: 0.376-1.000, P = 0.050), urban residence (OR = 0.443, 95%CI: 0.259–0.758, P = 0.003), suburban residence (OR = 0.047, 95%CI: 0.016–0.138, P < 0.001), higher income (OR = 3.889–7.928, all P < 0.001), and unclear self-reported depression level (OR = 0.078, 95%CI: 0.027–0.221, P < 0.001) were independently associated with the knowledge scores. Knowledge scores (OR = 1.102, 95%CI: 1.022–1.188, P = 0.011), female gender (OR = 0.437, 95%CI: 0.246–0.776, P = 0.005), city (OR = 0.410, 95%CI: 0.226–0.744, P = 0.003), married (OR = 3.577, 95%CI: 1.751–7.650, P < 0.001), higher income (OR = 0.065–0.392, both P < 0.050), depressive trend (OR = 2.640, 95%CI: 1.110–6.278, P = 0.028), high depression score level (OR = 0.176, 95%CI: 0.104-0.300, P < 0.001), and unclear self-reported depression score (OR = 0.023, 95%CI: 0.007–0.076, P < 0.001) were independently associated with the attitude scores. Finally, knowledge scores (OR = 1.130, 95%CI: 1.051–1.215, P = 0.001), attitude scores (OR = 1.199, 95%CI: 1.124–1.280, P < 0.001), and city (OR = 0.583, 95%CI: 0.352–0.965, P = 0.036) were independently associated with the practice scores. The structural equation modeling analysis showed that knowledge, but not attitude (β = 0.103, P = 0.092) or practice (β = 0.034, P = 0.603), influenced the depression level (β=-0.074, P < 0.001); attitude influenced practice (β = 0.369, P < 0.001). Conclusion The KAP toward exercise among MDD patients is poor in Shanxi. Females, people living in urban or suburban areas, with lower income, and self-reported unclear depression levels should be targeted by education interventions.
