BackgroundPsychological capital is closely related to primary school teachers' profession. It can not only promote the growth of teachers, but also directly affect the quality of school education and teaching and the growth of students. Therefore, it is particularly important to establish positive psychological capital in the pre service training stage of primary school teachers. The purpose of this study is to understand the current situation of the psychological capital level of primary school pre service teachers in China and the differences under the influence of different factors, so as to provide a basis for the relevant research on improving the psychological capital level of primary school pre service teachers. The corresponding training suggestions are put forward.Subjects and MethodsThis study selected 864 pre service teachers majoring in primary education from four normal universities and three comprehensive universities in China, conducted a survey through the Internet, and collected 831 valid questionnaires. According to the four dimensions of psychological capital, this study designed a questionnaire of psychological capital of pre service primary school teachers to investigate the level of psychological capital of pre service primary school teachers.ResultsThe survey results showed that the psychological capital of pre service primary school teachers was generally at the upper middle level. There are significant differences in the overall level and dimension of pre service primary school teachers' psychological capital in terms of gender, origin and family economic status. Gender, family background and family economic status have a significant impact on the psychological capital level of pre service primary school teachers. Through the research, we found that citizens with higher levels of psychological capital have lower levels of anxiety and depression. Therefore, we can think that citizens with high internal psychological capital can alleviate the psychological pressure, anxiety and depression brought by psychological capital to a great extent through their own psychological quality. We also found that relatively speaking, citizens with high individual psychological capital are less affected by family factors, work and life, traffic safety, their own health and future fear. Teachers with high level of psychological capital will deal with the influence of family factors well. They are full of hope for the future and optimistic about life, and will not worry too much about the impact of life. From the questionnaire survey results, the internal consistency: odd and even split half reliability coefficient is 0.86 (Spearman Brown correlation coefficient is 0.93). Retest consistency: the stability coefficient of the scale retested within a few weeks is usually 0.70-0.80. It shows that the influence of students' Psychological Capital on anxiety is very key. If the patient is asked to answer according to the situation of the day, BDI evaluates state anxiety. If the patient is asked to answer according to the situation of the past week, the stability is much better. From the aggregation validity: BDI was significantly correlated with the evaluation of clinical depression, and the correlation coefficient was 0.60-0.90, which varied with the sample size. BDI score is also related to other clinical indicators, such as biological examination, electrophysiological examination, psychosocial test and the degree of sleep disorder. Therefore, its correlation with other scales must be good (r value range is 0.50-0.80). Factor analysis of BDI often leads to three interrelated factors: negative attitude or suicide, physical symptoms and operational difficulties. When the three factors are further (secondary) extracted, a “overall depression” factor can be obtained. The correlation of three skew factors and the generation of a single quadratic factor show that the internal consistency of the scale is good. Discriminant validity: the correlation between BDI and clinical depression (0.59) was greater than that with anxiety (0.14). Some authors doubt the discriminant validity of BDI, especially for anxiety and depression, but it can be used to distinguish different types of depression and different diagnoses. In addition, the answer to BDI items may be affected by social expectations, that is, to answer according to expectation tendency. The correlation between BDI and Edwards social expectation scale is about 0.80, because the latter partially shows people's self-esteem.ConclusionThe survey found that although the psychological capital of pre service primary school teachers is generally at the upper middle level, there is still much room for improvement. In order to enable pre service primary school teachers to better engage in the profession of primary school teachers, the improvement and training of psychological capital should be incorporated into the mental health education system of pre service primary school teachers, and pre service primary school teachers should be trained in optimism, hope, health and health, self-efficacy and resilience, so as to develop their own psychological potential and improve their competitive advantage.
