The Attentional Control Scale (ACS) is a tool developed to assess the ability to voluntarily control attentional resources. The current aim was to verify the factor structure of the scale and its hypothesized inverse relationship with measures of trait anxiety on Slovak sample. The Principal Component Analysis (PCA) suggested two correlated factors resembling the hypothesized Focusing and Shifting subscales. The factorial solution suggested by the PCA had the best fit against one-factorial and two-factorial orthogonal solutions in the Confirmatory Factor Analysis (CFA) conducted on an independent sample. The entire scale had good internal consistency (ωt = .85). The Focusing (ωt = .81, αord = .81) and Shifting (ωt = .67, αord = .66) subscales reached acceptable to good values of internal consistency. The ACS showed a negative relationship with trait anxiety inventory and behavioural inhibition scale. The differences of our results compared to other studies investigating factor structure of ACS are discussed, together with limitations of the current study, validity and applicability of the scale.

The presented study was focused primarily on a psychometric analysis of the Attentional Control Scale (ACS), but they also enhanced the understanding of the role of effortful attentional skills in determining the individual well-being, general adaptation or emotional disorders. The analyses included basic item and scale descriptions as well as convergent and discriminant validity. 218 Polish undergraduate students completed the battery of the self-report techniques and two paper - pencil attentional tests. Data revealed a unidimensional of a 20-item ACS. It can be used validly to assess long-term individual differences in attentional skills related to the voluntary executive functions. The analysis of content, internal and construct validity as well as reliability provided evidence of the scale's significant convergent and discriminant validity when correlated with attentional tests and other personality techniques. We found strong, systematic relations between the attentional control and selected measures of temperament, arousal, emotionality, and motivation. The results allow assuming that good attentional control, may protect individuals from the emotional disorders by regulating perceptual, conceptual, and response processing.
