Objective To explore the relationships among negative life events,meaning in life and suicidal risk of college students.Methods A total of 897 students from southern medical university were surveyed by adolescent life events scale (ALES),suicidal behaviors questionnaire-revised (SBQ-R) and meaningful life measure-Chinese revised (MLM-CR).Results The scores of negative life events,meaning in life and suicidal risk were 1.03±0.88,124.32±20.35 and 4.17± 1.66,respectively.There were 64 (7.1％) college students with high risk of suicide.The overall stress score was positively correlated with total suicidal risk score (r=0.134,P＜0.01).Total suicidal risk score was negatively correlated with total score of meaning in life(r=-0.340,P＜0.01).Moderating effects of meaning in life between negative life events and suicidal risk were significant (P＜0.01).Meaning in life fully mediated the effects of negative life events on suicidal risk (P＜0.01),which accounted for 59.6％ of the total effects.Conclusion Meaning in life as a mediator and moderator between negative life events and suicidal risk.Meaning in life might play protective role in reducing the suicidal risk.

Objective To revise and evaluation the psychometric properties and usability of the Personal Meaning Profile Brief( PMP-B) . Methods 1256 university students were measured by PMP-B, Purpose in Life ( PIL) and the Satisfaction with Life Scale ( SWLS) ,and 234 university students were meas-ured by Meaningful Life Measure ( MLM) .321 university students were measured by PMP-B twice at differ-ent time after four weeks to analyze the reliability and validity of PMP-B. Results The items discrimination indices were all above 0.4(r=0.470-0.833,P<0.01). The internal consistency reliability of PMP-B was 0.957,the split-half reliability was 0.936 and the test-retest reliability was 0.852. Confirmatory factor analysis confirmed the hypothesized seven-factor model of PMP-B (χ2/df=3.17,GFI=0.965,AGFI=0.947,RMR=0.042,NFI=0.977,CFI=0.982,RMSEA=0.042). The criterion correlations with PIL,MLM and SWLS were 0.710,0.842 and 0.756 respectively (P<0.01). The PMP-B total score of the university students was (112.07±20.02),and female had high life meaning than male which was more positive in interpersonal rela-tionship,life belief and self-acceptance. Conclusion The reliability and validity of PMP-B are favorable,it can assess people''''s life meaning from different sources.

Objective To test the reliability and validity of Meaningful Life Measure-Chinese Revised (MLM-CR) in Chinese college students. Methods A total of 1035 college students were evaluated with MLM-CR, Satisfaction with Life Scale (SWLS), Purpose in Life (PIL) and Patient Health Questionnaire-2 (PHQ-2), and 120 of the students were examined with PIL-SF twice. Result All the items in MLM-CR had good discrimination indexes (r=0.753-0.838, P<0.001). Confirmatory factor analysis confirmed the hypothesized five-factor model of MLM-CR (χ2/df=3.4, GFI=0.946, AGFI=0.924, RMR=0.069, NFI=0.953, CFI=0.966, RMSEA=0.048). The total internal consistency reliability of MLM-CR was 0.942, and the alpha coefficients of the 5 dimensions ranged from 0.782 to 0.877;the total split-half reliability was 0.920, and the split-half reliability of the 5 dimensions ranged from 0.752 to 0.830;the total test-retest reliability was 0.871, and the test-retest reliability of the 5 dimensions ranged from 0.783 to 0.805. The criterion validity of MLM-CR in correlation with SWLS, PIL and PHQ-2 was 0.66, 0.755 and-0.388, respectively (P<0.01). The Average score of MLM-CR of the college students was 5.20 ± 0.90, and the scores were significantly higher in female students than in the male students (P<0.001). Conclusion MLM-CR has good psychometric properties for application in comprehensive evaluation of personal meaning in life.
