Objective: To explore the structure of concept of the Internet-related social-psychological health for undergraduates and develop The Internet-related Social-psychological Health Scale for Undergraduates (ISHS-CS). Methods: Employing exploratory factor analysis and confirmatory factor analysis of the data of ISHS-CS.based on 2 samples of 511 and 581 of undergraduates respectively. Results: ① The structure of Internet-related social-psychological health for undergraduates consisted of 5 primary factors, viz. loneliness, social involvement, general depression, life happiness and life satisfaction. These five factors could be generalized into 2 higher-order dimensions, namely social health and psychological health. The ISHS-CS had satisfactory item validity, internal consistent reliability, construct validity and criterion-related validity. ② Relation of time of Internet use to Internet-related social-psychological health was unremarkable, but, some relation between frequency of internet use and social-psychological health was found. ③ Compared with the undergraduates based on Social-affective motive of Internet-use, those based on Information-acquisition motive possessed higher level of Internet-related social-psychological health. Conclusion: The concept of Internet-related social-psychological health was a reasonable construct for undergraduates, and the ISHS-CS could serve as a measurement of Internet-related social-psychological health for undergraduates.

Based on the existing literatures,four basic models for drug addiction and relapse behavior researches were generalized,namely,the motive and self-concept model,the social-environment model,the cognitive processing model,and the neuropsychological model.Analyzing the research evidence in the area,the authors considered that relapse behavior was caused by a great many diverse factors,consequently,any of these models failed to make strong predication for relapse behavior.After reviewing the addiction models,the possibilities of future integrative research in the area were discussed.
