A Generalizability Analysis of the Mobile Phone Addiction Tendency Scale for Chinese College Students

Abstract

College students’ mobile phone addiction is negatively associated with physical and mental health and academic performance. Many self-made questionnaires are currently being administered to Chinese college students to evaluate the mobile phone addiction tendency. Using the univariate generalizability theory and multivariate generalizability theory, this study investigated the psychometric properties and the internal structure of the Mobile Phone Addiction Tendency Scale (MPATS), the most widely used survey questionnaire assessing the status of Chinese college students’ mobile addiction. Data were a sample of 1,253 college students from the southwest of China. Primary analytic approaches included the generalizability design of univariate random measurement mode p × ( i : h ) and multivariate random measurement mode p ˙ × i° . Results showed that the variance component of the participants and the variation related to the participants explained most of the variation of the scale, while the variance component of the items was small, and the generalizability coefficient and dependability index of the scale were 0.88 and 0.85. In the multivariate generalizability analysis, the variance component of the participants and the variation related to the participants accounted for most of the variation of the scale and the variance component of the items was small. The generalizability coefficients of withdrawal symptoms, salience, social comfort, and mood changes were 0.64–0.80, and the dependability indexes were 0.63–0.77. However, the generalizability coefficient and reliability index of universe score were 0.91 and 0.90. In addition, the contribution ratio of the four dimensions to the universe score variance was different from the assignment intention of the initial scale. Recommendations were discussed on the improvement of the test reliability for each dimension.

Longitudinal relationships among problematic mobile phone use, bedtime procrastination, sleep quality and depressive symptoms in Chinese college students: a cross-lagged panel analysis

“…PMPU was measured using the MPATS, developed by Xiong et al [27] and widely used to evaluate the PMPU of college students, showing good reliability and validity in China [64]. This scale includes 16 items with a fourfactor structure, including withdrawal symptoms (six items), salience (four items), social comfort (three items), and mood changes (three items).…”

Stroop effect in smartphone addiction among college students

“…The retest reliability of the 4 factors is 0.75 to 0.85. [18][19][20] The questionnaire (Table 1) was filled in a quiet environment. The reliability of the questionnaire was confirmed through phone communication with their parents and by asking classmates in the same dormitory whether the subjects often used smartphones for internet access and whether the roommates were disturbed.…”

Prospective Association Between Problematic Mobile Phone Use and Eating Disorder Symptoms and the Mediating Effect of Resilience in Chinese College Students: A 1-Year Longitudinal Study

“…PMPU was assessed using the Mobile Phone Addiction Tendency Scale (MPATS) ( 43 ), which is widely used in China ( 44 ). Participants rated the 16 items on a five-point Likert scale (from 1 “very inconsistent” to 5 “very consistent”).…”
