Sluggish Cognitive Tempo Self Report Scale (SCT-SR): Development and Initial Validation Study.

Objective: Sluggish Cognitive Tempo (SCT) is a psychological construct consisting of daydreaming, confusion, slowness in movements, lethargy, and low motivation. It is important to develop a self-report scale to evaluate SCT symptoms in children and adolescents in order to meet the following needs; (1) Considering the closeness of SCT symptoms with internalized symptoms, it can provide more reliable information, (2) It allows information to be obtained from multiple informants, and (3) The main symptoms of SCT include subjective experiences such as daydreaming and mind wandering that may be difficult to observe from the outside. Therefore, it was aimed to develop a self-report SCT scale.

Method: A total of 467 adolescents and 178 parents participated in the study. Data were collected with scales.

Results: The scale consists of 20 items and a single factor. Factor loadings were between 0.60 and 0.81.

Conclusion: Sluggish Cognitive Tempo Self-Report Scale is a valid and reliable self-report scale.
