Subjective and objective evaluation of psychological resilience training on regulation of sleep quality in pilots
Objective To formulate the development of an autonomous training program for psychological resilience in order to enhance the psychological resilience of pilots,improve their stress resistance and sleep quality,and prove the utility of this training method.Methods A total of 234 pilots who were recuperating in Dalian Rehabilitation Center of Joint Logistic Support Force of PLA from March 2021 to January 2023 were randomly stratified and divided into a training group and a control group.In addition to routine recuperation,the training group received an autonomous training program for psychological resilience,while the control group did not.The Connor Davidson Resilience Scale(CD-RISE)was used to evaluate changes in psychological resilience,and the Pittsburgh Sleep Quality Index(PSQI)and Polysomnography(PSG)were adopted to evaluate subjective and objective quantification of sleep quality and study the effects of this training on sleep.Results The resilience factor(t=2.534,P=0.025),belief factor(t=2.379,P=0.032),and total psychological resilience score(t=2.490,P=0.028)of the training group increased after training,and the differences were statistically significant.After training,the training group showed significant improvements in subjective sleep quality(Z=3.918,P＜0.001),sleep time(Z=2.201,P=0.027),falling asleep time(Z=2.178,P=0.037),sleep efficiency(Z=2.378,P=0.018),sleep disorders(Z=3.228,P=0.001),daytime dysfunction(Z=4.908,P＜0.001),and PSQI total score(Z=3.790,P＜0.001).The subjective sleep quality(Z=2.804,P=0.020),sleep time(Z=2.200,P=0.028),falling asleep time(Z=2.073,P=0.048),and PSQI total score(Z=2.992,P=0.016)of the control group improved to a certain extent after routine recuperation.The results of multi-channel sleep monitoring data showed that after training,the total sleep time(t=6.973,P=0.015),sleep latency(t=5.166,P=0.032),REM latency(t=5.490,P=0.028),and sleep efficiency(t=5.021,P=0.041)were significantly different.During the non-rapid eye movement phase,the sleep time in N1 phase decreased(t=5.247,P=0.036),but that in N2 phase(t=6.268,P=0.023)and N3 phase(t=5.232,P=0.038)increased(P＜0.05).The control group showed improvement in both subjective and objective sleep indicators,but the difference was not statistically significant(P＞0.05).Conclusion The psychological resilience training program can improve the psychological resilience of pilots,and there is a significant improvement in the subjective and objective experiences of sleep quality.
