Objective: To explore the effect of nursing intervention based on the integration theory of health behavior change on pelvic floor muscle exercise in patients with pelvic floor dysfunction after early cervical cancer surgery.Methods: Select 40 patients with pelvic floor dysfunction after surgery for early cervical cancer, and divide them into experimental group (20 cases) and control group (20 cases) by random number table method. Based on the pelvic floor muscle exercise based on the integration theory of healthy behavior change, the control group received routine pelvic floor rehabilitation nursing, and Oxford pelvic floor muscle strength was used before the intervention (T0), after 1 month of intervention (T1) and at the end of the intervention (T2). Scoring systems, Short Form of Pelvic Floor Dysfunction (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), General Self-Efficacy Scale (GSES), and Social Support Rating Scale (SSRS) were assessed.Results: (1) In terms of pelvic floor muscle strength, the muscle strength ratings of TO, T1 and T2 in the control group were (1.10±0.70), (1.46+0.64 (1.90+0.70), respectively, and (1.12±0.73) in the experimental group. , (1.96±0.73), (3.04+0.81) levels, the difference between the two groups at each time point after intervention was statistically significant (F group=25.730, F time=329.809, F interaction=56.688, all P<0.001); (2) On the PFDL20 score, the total scores of TO, T1 and T2 in the control group were respectively (80.19+18.75)>(78.67+17.99 (77.47+15.91) points, the test group was (77.77+19.97 ) >(69.11±15.97), (66.54+14.04) points, the difference between the two groups at each time point after the intervention was statistically significant (F group=6.876, F time=62.536, F interaction=29.196, all P<0.05); ( 3) On the PFIQ-7 score, the total scores of T0, T1 and T2 in the control group were (82.80+12.04)> (80.88+11.62)> (78.39+8.51) points, and the experimental group were (82.66±11.24), (82.66±11.24), (80.88+11.62) 76.69±10.12) and (73.20+7.41) points, the difference was statistically significant between the two groups at each time point after the intervention (F group=3.551, P=0.062; postmortem time=69.943, F interaction=13.213, all P<0.001 ); (4) In general self-efficacy, the total scores of TO, T1 and T2 in the control group were (2.44±0.53), (2.49+0.49) respectively (2.51+0.34) points, the experimental group was respectively (2.47+0.53)> (2.67+0.38 (2.86+0.30) points, the difference between the two groups at each time point after the intervention was statistically significant 3 group = 6.788, F time = 50.994, F interaction=25.664, all <0.05); (5) In terms of social support, the total scores of T0, T1 and T2 in the control group were (45.16±3.28), (45.84±3.02),(46.42+2.82) points, and the experimental group were respectively (45.48+3.43(48.25+2.83)> (5037+2.45) points, the difference was statistically significant between the two groups at each time point after the intervention (F group=20.12, F time = 199.34, F interaction = 70.24, both P<0.001).Conclusion: Nursing intervention scheme based on the integration theory of health behavior change can significantly improve the pelvic floor muscle strength, self-efficacy, social support level and quality of life of patients with pelvic floor dysfunction after early cervical cancer surgery, and improve the short-term and long-term pelvic floor rehabilitation.
