RESUMEN
Objective To explore the influence of psychological first aid training on cognitive appraisal of sudden events in medical students.Methods A medical university undergraduate students were selected and divided into the training group(n=42) and the control group(n=53).The former was treated with 20 hours short-term targeted psychological first aid,and the latter was treated as blank control.The SAM and LMSQ were adopted to measure students' cognitive appraisal before and after the training.Results After the training,the training group gained significant differences (P＜ 0.05) in threat (11.95 ±3.17) vs (10.45±2.48)(t=2.426,P=0.020),challenge (12.64t2.84) vs (14.40±1.95)(t=-3.304,P=0.002),controllable-by-self (13.05±3.15) vs (14.93±2.00) (t=-3.240,P=0.002),controllable-by-others (12.40±3.10) vs (14.52±2.52) (t=-3.553,P=0.001),stressfulness (13.26±2.69) vs (12.00±1.96) (t=2.592,P=0.013) of SAM,and Physical threat ((23.88±7.59) vs (19.76±4.82),t=3.057,P=0.004) of LMSQ compared with before training.Other factors had no significant difference(P＞0.05).Compared with two groups,the training group gained significant increase(P＜0.05) on the score differences for SAM factors (challenge (t=-2.466,P=0.016),controllable-by-self (t=-2.557,P=0.012),controllable-by-others (t=-2.800,P=0.006)) than the control group,and significant reduction (P＜0.05) in physical threat (t=-2.308,P=0.023) of LMSQ.Conclusion Short-term targeted psychological first aid training has certain effects on changing cognitive appraisal about sudden events for medical students.
