Factor Structure of a Modified Situational Motivation Scale and Inferences to Motivational Antecedents of Hyperfocus 

Master’s Thesis from the year 2021 in the subject Psychology – Miscellaneous, grade: 1, 7, University of Groningen, course: Klinische Neuropsychologie, language: English, abstract: Hyperfocus describes a condition of intense concentration on a task, accompanied by a lack of self-, time-, and environment-awareness. To date, only scarce research examined its characteristics and determinants. Hyperfocus appears to lie on the deep side of the flow continuum. Since flow involves intrinsic motivation, it was hypothesized that intrinsic motivation predicts hyperfocus. A modified version of the Situational Motivation Scale (m SIMS) was applied to measure potential motivational predictors of hyperfocus, consisting of adapted and newly created items measuring motivation in line with self-determination theory and task demands, respectively. Predominantly healthy students and working students (n = 331) filled out the questionnaire online. The motivational impact on hyperfocus was analyzed using hierarchical multiple linear regression. Exploratory factor analysis on the m SIMS revealed four factors: intrinsic motivation, autonomous extrinsic motivation, controlled extrinsic motivation, and amotivation. The regression model explained 22% of the variance (p
