ABSTRACT
The objective of this study was twofold: to validate the Watching TV Series Motives Questionnaire (WTSMQ) for the Portuguese population and to understand its relationship with loneliness. WTSMQ was validated through an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA). Besides, multi-group CFAs according to gender were conducted having been tested four levels of measurement invariance: configural, metric, scalar, and error variance. Several multiple linear regressions were carried out to estimate the relationship between sociodemographics, series preferences, loneliness and watching TV series motives. Results showed that the Portuguese version of WTSMQ presents good psychometric properties and that configural and metric were achieved, but not scalar and error variance invariance providing some evidence that the WTSMQ operates similarly in males and females. Results also showed that gender, age, TV series preferences, and loneliness contribute to explain different dimensions of Watching TV Series Motives. Also, sociodemographic variables, TV series preferences and WTSMQ subscales explain loneliness. The relationship between the motives for binge-watching and loneliness is bidirectional; sociodemographic variables and series preferences that explain those motives and loneliness overlap. Implications for tracking problematic Binge-watching situations are discussed. (AU)
