RESUMO
Objective:To examine the multiple mediating effects of cognitive fusion and network communication in the relationship between interpersonal relationship and mobile phone addiction tendency in college students.Methods:Questionnaire survey was conducted among 708 college students in a medical school using the mobile addiction tendency scale, E-communication inventory, Interpersonal relationship assessment scale and cognitive fusion questionnaire.SPSS 17.0 software was used for descriptive statistics and correlation analysis.Structural equation model was built with AMOS 21.0.The non parametric percentile bootstrap method with variance correction was used to test the significance of mediating effect.Results:(1) The sample mobile phone dependence detection rate was 13.56%.(2)There were statistical differences in conversation scores((3.49±1.85), (2.51±1.64)), making friends ((4.53±1.83), (3.21±1.72)), getting along with opposite gender((2.70±1.55), (2.01±1.60)), dealing with people disturbance(2.02(1.00, 3.00), 1.46(0.00, 2.00))between different mobile phone addiction tendency( t/ Z=2.752-5.072, P<0.05). There were statistical differences in cognitive fusion ((40.60±7.55), (33.91±7.95)) between different mobile phone addiction tendency( t/ Z=5.385, P<0.05). There were statistical differences in negative results of network communication((28.60±6.77), (23.31±7.03)), social perception of network communication((32.36±6.68), (29.17±7.82)), self exposure and emotional experience of network((23.36±6.61), (18.18±6.30)), cognition of network communication((28.19±6.85), (22.75±6.76)), entertainment of network ((6.74±1.81), (6.00±1.67)) between different mobile phone addiction tendency( t/ Z=2.647~5.195, P<0.05). (3) There was a statistically significant positive correlation between interpersonal relationship, mobile phone addiction tendency, cognitive fusion, and E-communication inventory scores ( r=0.226-0.423, P<0.01). (4) Multi-mediating model analysis showed that interpersonal relationship could affect mobile phone addiction tendency through cognitive fusion and network communication not only in a parallel way but also in a chain way.The direct effect from interpersonal relationship to mobile phone addiction tendency was 0.20, and the total indirect effect from interpersonal disturbance to mobile phone addiction tendency through cognitive fusion and network communication was 0.18.And the effects of cognitive fusion, network communication, and the chain mediating accounted for 50.0%, 33.3%, and 16.7% of the total indirect effect respectively.The 95% CI of the Bootstrap output were (0.04-0.19), (0.02-0.14)and(0.01-0.05). Conclusions:College students' interpersonal disturbances affect mobile phone addiction tendency through multiple mediations of cognitive fusion and online communication.
