Factor structure and measurement invariance of the cognitive failures questionnaire across the adult life span by means of confirmatory factor analysis of ordered-categorical variables. A three-factor model of the CFQ from an exploratory factor analysis was tested for increasing levels of measurement invariance across six age groups. Factor (co-)variances remained stable across the age groups, mean differences were observed for the factor "Forgetfulness", with higher means for older participants, and the factor "Distractibility", where participants older than 60 years of age had lower means. Another prominent account of everyday slips and errors is proposed by Broadbent et al. (1982). A cognitive failure "… may involve perceptual failures, failures of memory, or physical actions which are misdirected. The common element is that there is a departure from the normal smooth flow of function, and events do not proceed in accordance with intention" (p.1). The assumption underlying cognitive failures is that various perceptual, action, and memory failures are influenced by a general and rather enduring factor. This factor might be described as a general proneness or liability to cognitive failures which should be relatively independent of traditional personality and intelligence measures (cf. Klumb, 2001). conscientiousness, and everyday memory). In a sample of 386 undergraduate students he found that the frequency of self-reported cognitive failures correlated positively (rs = .50 to .53) with similar constructs, whereas the associations with opposite constructs were negative (rs = -.13 to -.41). The broad acceptance and usefulness of the CFQ are also reflected by the fact that the CFQ has been translated into several languages, for example, Dutch (Merckelbach et al., 1996), German (Klumb, 1995), Hebrew (Meiran et al., 1994) and Spanish (García Martínez & Sánchez-Cánovas, 1994). In summary, the CFQ is a commonly used questionnaire which has proved to be a useful instrument to identify individuals prone to cognitive failures.
Factor Structure of the CFQIn most applied studies the sum score across all CFQ items is used as a measure of being prone to everyday slips and errors, based on the assumption that the CFQ captures a general liability of cognitive failures. In accordance with this assumption, Broadbent et al. (1982) conducted a number of factor analyses in different samples and concluded that a single, general factor of cognitive failures adequately captured the dimensional structure of the CFQ. The authors found that apart from the "obvious general factor" (p. 5), results were rather variable.Subsequently, however, several investigators re-examined the factor structure of the CFQ and their results seem to question the notion of only one single and general factor (Larson, Alderton, Neideffer, & Underhill, 1997;Pollina, Greene, Tunick, & Puckett, 1992;Wagle, Berrios, & Ho, 1999;Wallace, 2004;Wallace, Kass, & Stanny, 2002).
