ObjectiveTo compare the characteristics of adult and juvenile callers at high risk of suicide from psychological assistance hotline， to screen factors influencing the crisis intervention effect， so as to develop specific intervention programs for different age groups on psychological assistance hotline. MethodsFrom January 2021 to June 2021， a total of 2 229 callers at high risk for suicide were recruited from Beijing psychological assistance hotline. The selected individuals were divided into adult group （n=1 344） and juvenile group （n=885）. Callers were interviewed by the hotline operators. Their general information， suicidal ideation， socio-psychological characteristics and chief complaints were recorded and compared between two groups. Before and after hotline crisis interventions， psychological distress， suicidal ideation intensity and hope level of the callers were assessed， and the improvements in the three assessed dimensions were compared between two groups. Then Logistic regression was adopted to compare the crisis intervention effects on three dimensions and their associated factors. ResultsCompared with adult group， juvenile group reported higher rates of family relationship problems， learning problems， history of suicide attempts and fear of assault， with statistically significant differences （χ2=55.604， 24.706， 41.944， 106.527， P<0.01）. After hotline crisis intervention， the proportion of callers with increased level of hope was larger in juvenile group than that in adult group （42.74% vs. 30.97%， χ2=26.042， P<0.01）. Multivariate Logistic regression analysis showed that the chances of improvement in psychological distress for major depressive disorder （OR=0.650， 95% CI： 0.510~0.827）， the chances of improvement in the level of hope for those with substance dependents （OR=0.550， 95% CI： 0.327~0.926）， and the chances of improvement in the intensity of suicidal ideation for those with stressful life events （OR=0.565， 95% CI： 0.328~0.973） were all higher in juvenile group than those in adult group after crisis intervention. ConclusionAmong the callers at high risk for suicide from psychological assistance hotline， adult callers are more concerned about extra-familial relationships， work and economic problems， while juvenile callers are more concerned about family relationship and learning problems. Furthermore， the effect of crisis intervention in juvenile callers is less affected by major depressive disorder， substance use problems and stressful life events.
Résumé
Objective To analyze bacterial epidemiological characteristics of adult foodborne diarrhea cases in Jinan from 2013 to 2019, and to provide references for the prevention and control of foodborne diseases. Methods Using SPSS21.0, the pathogen detection results of 1513 adult diarrhea cases reported by the foodborne disease surveillance sentinel hospital in Jinan was analyzed. Results The positive detection rate of the pathogen of foodborne diarrhea in adults was 46.07%. Among these, the positive rate of bacterial infection was 30.60%, mainly Escherichia coli; the positive rate of norovirus infection was 20.29%, and the main infection genotype was GⅡ; and the positive rate of bacterial-virus infection was 4.82%. The difference in pathogen positive detection rates in different quarters was statistically significant (χ2=11.894, P=0.008). Bacterial infection was the main factor during the second to the fourth quarters, while viral infection became critical in the second and the fourth quarters. The top three suspected exposure foods were meat and meat products (18.77%), mixed foods (14.83%), and fruits and their products (14.35%). Conclusion The positive rate of adult foodborne diarrhea pathogens in Jinan is relatively high. It is recommended to increase sentinel monitoring hospitals. At the same time, the foodborne disease prevention and control measures should be developed based on seasonal changes, different age groups, and different characteristics of exposed food.

Objective:To develop the Counseling Skills Rating Scale for Psychological Aids Hotline (CSRSPAH),an instrument to objectively assess the quality of process of counseling or intervention provided by hotline operators,and to test its validities and reliabilities.Methods:A draft of the scale,which consisted of 50 items under 5 dimensions,was designed in line with previous researches and the practice.In pilot study,supervisors at Beijing psychological aids hotline,assessed tape recorded sessions and gave feedbacks on the draft of the scale.The scale had been revised based on the pilot study.Twenty-eight items were deleted,and several items were rephrased.Finally,a scale which consisted of 22 items within 3 dimensions,i.e.counseling process,attitude,and communication skill,was developed.The scoring standards of the scale were also developed.To evaluate the IntraClass Coefficients (ICC) of the CSRSPAH,each of the tape records of 37 callings from 2005 to 2007 were assessed by 7 supervisors independently,using the scale.And the tape records of other 318 callings from 2013 to 2014 were also assessed by supervisors,using the CSRSPAH.The results of the 318 assessed callings were used to test the construct validities with the Confirmative Factor Analysis.The Cronbach a coefficients of the total score and three dimensions,the discriminant indices of every items,and correlations of each items and each dimensions were calculated,based on the 318 assessed callings.Results:One of the items (referral) was deleted due to excessive amount of missing data.Results of cortfirmative factor analysis of the remained 21-item scale revealed that the 3-factor construct structure of the scale was robust.The fitting indices of the confirm factor analysis were,x2/df=675.21/186,CFI =0.92,NNFI =0.91,RMSEA =0.10,SRMR =0.08.The Cronbach α coefficients of the total score,scores of counseling process,attitude,and communication skill,were 0.89,0.68,0.81 and 0.77,respectively.The ICCs of the inter-rater reliabilities of the total score and 3 dimensions of the scale were 0.67,0.59,0.59,and 0.67,respectively.The discriminant indices of all the 21 items ranged from 0.09 to 0.32.The correlation coefficients of scores of each items and scores of 3 dimensions and total scores were greater than 0.30,and reached statistical significance.Conclusion:The validities and reliabilities of the Counseling Skills Rating Scale for Psychological Aids Hotline are acceptable.The scale could be used in assessing the quality of hotline counseling or intervention,and related studies in the future.
Résumé
Objective To conduct concordance test on Life Event Scale reported by different informants and the suicide-attempters themselves in Chinese suicide research. Methods In this retrospective study, 104 attempted suicide cases and 147 suicide cases were included. Each case had two informants. One was family member, and the other was associate (friends, neighbors, etc.). Suicide attempters (only for attempted suicide cases) were also interviewed by qualified psychiatrists. Life Event Scale was administered to each respondent to obtain life events experienced by the case before the suicidal behavior. Kappa and Intraclass Correlation Coefficient (ICC) were used to compare the suicide attempters' self-reports with two informants' reports, and to present the concordance of two informants' reports for suicides. Results For attempted suicide group, agreements were nearly moderate or better for life events on marital relation, physical illness, family relation, love, birth or death of family members (Kappa≥0.39); Proxy-based chronic stress and acute stress scores were significantly lower than subject-reports (ICC:0.11~0.24, P<0.01).For suicide group, the agreements between the two informants' reports were moderate or better on death of spouse, work/study or physical illness (Kappa≥0.49); The agreement for chronic stress score was fair (ICC=0.47). Conclusions The results have demonstrated that proxy-based data on life events are valid if structured and objective scales are used.
Résumé
Objective To Compare characteristics between the psychological aids hotline callers who had single attempted suicide and those callers who had repeated attempted suicide. Methods The analysis was conducted on the da?tabase of Beijing psychological aids hotline from Dec., 2002 to Dec., 2008. All the effective callers were consulted by pro?fessional hotline operators. During the calling, the callers were interviewed on their attempted suicides, depression and 11 correlates associated with caller's suicidal behaviors. Results Among 4519 callers who had attempted suicide, 2441 (54%) of them had attempted suicide once, and the other 2078 (46.0%) callers had repeated suicide attempts. After ad?justed for gender, age, and the other 4 demographic variables, history of being abused (OR=1.35, 95%CI: 1.08~1.67), afraid of being attack (OR=1.35, 95%CI: 1.01~1.59), relatives or associates with prior suicidal behavior history (OR=1.17, 95%CI: 1.001~1.36), hopelessness (OR=1.20, 95%CI: 1.02~1.40), and psychological treatment history (OR=0.73, 95%CI:0.62~0.86) were associated with repeated suicide among hotline callers. Conclusions To improve the effective?ness of hotline based suicide prevention, assessment of risk of repeated attempted suicide among the callers with a histo?ry of prior attempted suicide should focus on the history of being abused, afraid of being attack, hopelessness, relatives or associates with prior suicide history, and psychological treatment history.
