Smartphone influence scale for adolescents in the behaviors of daily life

It is a Smartphone Influence Scale “SISA” on the daily behaviors of adolescents, an important screening tool in the prevention of behavioral problems related to smartphone overuse. 292 adolescents (11 to 14 years old) participated. Descriptive analyzes were performed to verify the consistency of the sample and the Bartlett and Kaiser-Meyer-Olkin tests to estimate the factors and commonality (h2) was used to indicate the explanatory capacity of the questions. Varimax rotation was applied in exploratory factor analysis to estimate the constructs. Spearman's correlation was applied to discriminate the non-collinearity of the questions. McDonald's (Ω) was used to estimate the internal consistency of the scale, globally and by domain. Analyzes were performed partially in SPSS 25.0 and partially in R, with a significance level of 5%. Participants had a mean age of 11.3 (SD 1.36) and most were men (52.1%). The confirmatory factor analysis that evaluated the SISA resulted in a 4-factor structure (emotional symptoms; change in daily life; virtual reality-oriented relationships and physical health). Validity and reliability analyzes showed significant correlations with SISA. The overall internal consistency of the scale (McDonald's Ω = 0.91). SISA showed significant reliability and validity to assess the use of smartphones in adolescents.
