A Research On The Questionnaire About Psychological Quality Of Software-developing Personnel

Aim:Design a test questionnaire about psychological quality of software-developing personnel and computerize preliminarily this questionnaire in order to provide large enterprises in China with efficacious psychological testing means for selecting software-developing talents with fine latent quality.Methods:1. Scaling: Settle the construction of the scale, set its item treasury based on the work analysis of software-developing personnel, then sift and settle items by using the experience mode and the conventional item analyzing technology (such as differential validity technology) simultaneously while taking into account expert assessment2. Testing: Take samples, which totals 72, from certain famous software companies (such as Huawei Company) and, controlling the factors that may influence working ability (such as sex), make statistical and logical analysis of the test result3. Reliability testing:(Internal consistency reliability. Calculate the consis-tency correlation coefficient of the scale with the data of the test samples.(2)Split-half reliability. Calculate the split-half correla-tion coefficient of the scale with the data of the test samples.4. Validity testing:(1) Content validity. Analyze and study the content validity of the scale using internal consistency factors.(2) Construction validity. Illustrate the construction vali-dity of the scale using factor analysis and consistency analysis.(3) Validity-criterion correlation validity. Use as three 3 validity criterions the placement of 30 new personnel separately of the training score, of the assessment of the immediate superior when probation expires and there follows a formalemployment, of the score of formal-employment defense, and then calculate the correlation of these 3 with the placement of the test score. Result1. Designs a test scale about psychological quality of software-developing personnel which consists of 96 items and is divided into 3 dimensions as ability, temperament and impetus by making surveying and logical analysis of the test scale and result2. The result of item analysis shows that most of the index of item discrimination were above 0.2.3. The consistency coefficient of the scale is 0.8081 and the Split-half correlation coefficient 0.8362.4. The result effector analysis shows that the 3 dimensions of the scale load 1 factor relatively largely.5. The correlation coefficients of the total score of psychological quality with the placement of training score, of the assessment of the immediate superior when probation expires and there is a formal employment, of the score of formal-employment defense are respectively 0.406,0.467 and 0.367.Conclusion.The assessment scale this research invents, which consists of 96 items and is divided into 3 dimensions as ability, temperament and impetus, is applicable to the ordinary software-developing personnel in the team-work mode in China. The surveying indexes such as reliability and validity are relatively satisfactory thus this scale can be used to test psychological quality of software-developing personnel.
