Effectiveness of a Self-Management Program for Patients Undergoing Lumbar Spinal Stenosis Surgery: A Quasi-Experimental Study

Purpose: This study developed a self-management program for patients undergoing lumbar spinal stenosis surgery utilizing the information-motivation-behavioral skills (IMB) model. Methods: This study employed a quasi-experimental design with a nonequivalent control group and pretest–posttest design. Data were collected from August 11, 2022, to March 31, 2023, at a general hospital in South Korea. A total of 58 patients participated in the study (30 experimental, 28 control group). The experimental group received a six-session self-management program based on the IBM model, whereas the control group received usual education and information. Data were analyzed with SPSS/WIN 23.0 using the independent t-test, chi-square test, Fisher’s exact test, Shapiro-Wilk test, and Mann-Whitney U test. Results: Significant differences were observed in self-management information (p<.001), personal motivation (p=.002), social motivation (p=.002), behavioral skills (p=.002), behaviors (p=.003), health-related quality of life (p<.001), and disc height (p=.006) in the experimental group following program implementation, compared to the control group. However, no significant differences were found in lower extremity muscular strength, lumbar lordotic angle, or the visual analog scores for low back pain and leg pain between the two groups. Conclusion: The self-management program developed in this study, based on the IMB model, was effective in improving self-management information, motivation, behavioral skills, behaviors, health-related quality of life, and self-management health outcomes in patients undergoing lumbar spinal stenosis surgery. Nevertheless, future research should aim to verify the long-term effects of such self-management programs by extending the intervention period.
