Objective: To explore the relationship between the parent-child relationship perceived by parents and students of junior high school and students internalization problems, so as to provide a pathway for the prevention and control of students internalization problems. Methods: In June 2023, a convenience cluster sampling method and a matching method between students and their fathers/mothers were used to select 965 pairs of students and their fathers (or mothers) from three junior high schools in Guizhou Province, and the Middle School Student s Parent-Child Relationship Questionnaire (parent and student edition) and the Strengths and Difficulties Questionnaire (student edition) were used to measure the perception of parent-child relationship by parents and students and the internalization problems of students. The response surface analysis method was used to analyze the relationships between parents and students perceptions of parent-child relationship and students internalization problems. Results: The comparison of standardized scores revealed that 58.44% of parents and junior high school students had different perceptions of parent-child relationship. After controlling for students gender, students grade, and parents education level, the results showed that when the parent-child relationship perceived by parents and students was congruent, the students internalization problems increased with the decrease of parent-child relationship level ( a 1=-0.43, 95%CI=-0.62 to -0.25, P <0.05). When the parent-child relationship perceived by parents and students was incongruent, and the parent-child relationship perceived by parents was higher than that of students, students internalization problems were more ( a 3=-0.36, 95%CI=-0.51 to -0.19, P <0.05). Conclusions Students internalization problems are closely related to perceptions of parent-child relationship. Improving the quality of the parent-child relationship and paying attention to the differences in perception of the parent-child relationship are helpful for evaluating and intervening in the internalization problems of junior high school students.

Objective To development a subjective quality of life of farmers and provide the evaluation of measurement tools of the the quality of life. Methods Established items library by policy learning,literature review, consulting experts, learn questionnaires, questionnaire surveying and interview, then about 536 farms and 332farms are picked out randomly as samples from Yunan and Henan provide,Item analysis,factor analysis and analysis of reliability and validity are executed. Results ( 1 ) Item analysis showed this questionnaire had satisfactory item discrimination,the correlations between items and total scores were significant,the correlation coefficient of items above 0.3. (2) Exploratory showed analysis find the factor loading range from 0. 425 to 0. 912 . Eigenvalue greater than 1, three sub-questionnaires cumulative total explained variance was 51. 603%, 50. 130% and 55. 676%. Confirmatory factor analysis had a higher goodness of fit. ( 3 ) Cronbacha' α coefficient range from 0.5989 to 0.9241 ,split-half reliability range from 0. 5897 to 0. 8936 and criterion validity range from 0. 125 to 0. 640. Conclusion The questionnaire has good reliability and validity,and can be used as a measurement tool for measuring the quality of life of farmers.
