Objective: To explore the latent structure of Antonovsky's Sense of Coherence(SOC) Scale(13-items) in China.Methods: Data from 656 Chinese subjects were analysed by EFA(exploratory factor analysis) and CFA(confirmatory factor analysis).Results: As a global construct,Antonovsky's theory that an individual's SOC is composed of meaningfulness,comprehensibility and manageability was supported.Conclusion: On the whole,Antonovsky's Sense of Coherence(SOC) Scale(13-items) was suitable to Chinese subjects,however several items of the scale were found to be unfit to the Chinese subjects,and revision of them should be done in further study.

Three problems about the concept of validity were discussed here,which is the evolution of concept of validity and its existing problems,a new understanding of validity and how to construct validity.During the development of the concept of validity,content validity,predictive validity,construct validity as well as concurrent validity were prevailing until the emergence of construct validity in which all aspects of validity were involved.To date,the bias we put on the concept of validity were mainly originated from the way by which we have taken concept of validity as a nomological network.Actually,the concept of validity is a ontological claim which is seriously based on reference and causality.We should establish a theory hypothesis,form a test,and confirm the measure attribute,so we could obtain the validity.

Objective:To develop a succinct and effective social support questionnaire for Chinese Farmers.Methods:Based on the studies of Vender Poel Mart et al and combined with the interview data of 53 farmers,a pro-questionnaire was developed;An item analysis was conducted with a sample of 800 farmers of Zhejiang province;CFA was used to test another sample of 807 farmers from Zhejiang and other provinces.Reliability and validity were also tested.Results:Then,9-item questionnaire was formed;EFA indicated that farmers' social support consisted of four factors,namely:instrumental support,company support,emotional support and the utilization degree of social support,which explained 79.23% of total variance;CFA showed the 4-factor model was well fitted;The Cronbaeh's ? of the questionnaire was 0.72 and the split-half coefficient was 0.64;The correlations between 4 factors were 0.10-0.30,and all factor-total correlations were over 0.50.Conclusion:The structure,reliability and validity of Chinese Farmers' Social Support Questionnaire meets the need of psychometrics.

Objective: To explore the relationship between learning adjustment and self consistency of normal university students. Methods: 423 students were tested by means of Self Consistency and Congruence Scale and Undergraduate Learning Adjustment Scale. Results: The whole situation of learning adjustment and self-consistency was quite well. There was significant correlation among most factors of learning adjustment and self consistency. Two elements of self consistency were effective predictive variables of learning adjustment. Conclusion: There is close relationship between self consistency and learning adjustment of normal university students.

Objective: To explore the influence of social support on Chinese farmers’ career choice consideration. Methods: Based on depth interviews and the pre-test on 419 farmers, a questionnaire of self-efficacy, choice consideration and social support related to occupations representing Holland's six RIASEC career types was developed. With a formal sample of 628 farmers, and by the structural equation modeling, the hypothetic models were constructed and tested. Results: Across most of the career types, there were significant paths between positive support and self-efficacy, self-efficacy and choice consideration, negative support and choice consideration; the goodness of fit of the final models were perfect. Self-efficacy fully mediated the relationship between positive support and choice consideration. Conclusion: The influence of social support on farmers' career consideration is ambilateral. Positive support has fully positive effect on choice consideration via self-efficacy, whereas negative support has direct negative effect on it.

Objective: To study the interpersonal interaction of junior high school students and its relationship with self-consciousness. Methods: 265 junior high school students were given the measurement of interpersonal relationship, and administered the questionnaire of Piers-Harris children self-consciousness one week later. Results: ①The interpersonal relationship of junior high school students was interactive. ②There were statistically significant differences among some dimensions of self-consciousness of junior high school students of different grades and genders. ③Intellgence and school performance had important effect on personal acceptance of junior high school students. Conclusion: There is interpersonal interaction among junior high school students, and intelligence and school performance influence the personal acceptance significantly.

Objective: A preliminary study on the Mental Health Test Modified. Methods: According to regionalism of Zhejiang Province, 2084 middle school students were sampled from 36 classes of 6 junior middle schools and 6 senior middle schools from 8 cities and towns. Results: The norm of the Mental Health Test Modified toward Zhejiang Province was made. The scores of students in junior middle school of Learning Anxiety, Sensitivity Tendency, Body Symptom, Hor- ror Tendency and Impulsion Tendency are higher than those of students in senior middle school. Among students of junior middle schools, the state of Self- accusation Tendency of Grade Two is more serious. Among students in senior middle school, the state of Learning Anxiety and Self- accusation Tendency, Sensitivity Tendency and Horror Tendency of Grade One are also more serious. Conclusion: There should be different emphases in the process of Mental Health Education for students of different grades.

Objective:To investigate the surgical techniques and advantages of Ti-Robot-assisted surgery for pelvic fragility fractures in the elderly.Methods:A retrospective review was performed on geriatric patients presenting with pelvic fractures at the Orthopedics Department of Trauma, China-Japan Union Hospital of Jilin University from September 2019 to December 2022. Minimally invasive procedures were executed with the assistance of the Ti-Robot, and the therapeutic outcomes were appraised. The cohort comprised 24 patients aged ≥60 years, consisting of 6 men and 18 women, with a mean age of 66.1±4.9 years (range, 60-77 years). Fourteen patients sustained high-energy trauma, while 10 encountered low-energy trauma. Fracture classification utilized the FFP system proposed by Rommens and Hofmann. The cohort included 20 patients with FFP II fractures (5 males, 15 females; 4 of type IIa, 12 of type IIb, and 4 of type IIc) and 4 patients with FFP III fractures (1 male, 3 females; all type IIIa). The Matta standard assessment scale gauged fracture reduction, while the Gras classification, with Ti-Robot assistance, assessed screw positioning. Postoperative functionality was holistically assessed based on the Majeed quantitative evaluation system, focusing on pain intensity, sitting, standing, walking, and daily activities. The visual analogue scale (VAS) gauged pain levels in patients with type II fractures, pre and 72 hours post-surgery.Results:According to the Matta standard assessment scale, postoperative fracture reduction quality in 24 elderly patients showed 18 as excellent, 4 as good, and 2 as fair, yielding a 92% (22/24) combined excellent and good rate. Based on the Gras classification, 52 screws were rated as excellent and 7 as good, achieving a 100% positive rate. Utilizing Majeed's modified pelvic fracture evaluation system, postoperative functional recuperation revealed 19 patients as excellent and 5 as good. There were no reports of severe internal disease exacerbations, neurological manifestations, infections, or intraoperative extensive hemorrhaging, with all patients remaining stable. Fractures exhibited robust healing during follow-ups, averaging a recovery time of 3.5±0.7 months (range, 3-5 months). The VAS for 20 patients with FFP type II fractures decreased from 6.3±2.0 pre-surgery to 4.1±1.4 post-surgery ( t=6.14, P=0.003), signifying substantial pain mitigation. Conclusion:In the elderly with pelvic fragility fractures, particularly type II, securing with channel screws is viable. The Ti-Robot-assisted minimally invasive approach is advocated due to its potential to diminish surgical risks and expedite postoperative recuperation.
