Abstract:
The purpose of this research was to develop and validate a causal relationship model of fear of missing out behavior among upper secondary school students in Thailand and Cambodia Border Provinces. The model consisted of four latent variable: intrinsic motivation, amotivation, extrinsic motivation, and fear of missing out behavior. The sample, selected by multistage random sampling, composed of 450 upper secondary school students in the second semester of 2016 academic year. Data were collected by using a seven point-rating scale. Descriptive statistics were analyzed using SPSS, and causal modeling was analyzed using LISREL 9.30 (Student Edition). Results indicated that the developed model was consistent with the empirical data as demonstrated by the following fit indicies: Chi-square test = 41.11, df = 39, p = .37, AGFI = .96, CFI = .99, SRMR = .02 and RMSEA = .01. The variables in the model accounted for 50 percent of the total variance of fear of missing out behavior. Academic motivation, including intrinsic motivation, amotivation, and extrinsic motivation, was the main cause of fear of missing out behavior. In addition, student characteristics including gender and GPAX were found as supporting causes.
