Self-Management Ability Questionnaire Validation in Portuguese Adults With Periodontitis.

OBJECTIVES: We aimed to test the psychometric validity of the adapted and translated Self-Management Ability Questionnaire-Short Form (SMAQ-12) to Portuguese. METHODS: The translation and adaptation of the SMAQ-12 followed international guidelines. We included 280 participants with chronic periodontitis from the Department of Periodontology of the Egas Moniz Dental Clinic. Participants completed the Portuguese version of the SMAQ-12 (SMAQ-12-PT), a 12-item scale with 3 conceptual domains (Role Management, Medical Management, and Emotional Management). The validity of the content, its construct and internal consistency, as well as test-retest reliability were used to estimate psychometric properties. RESULTS: The SMAQ-12-PT showed an interclass correlation coefficient value of 0.90, with a 95% confidence interval (0.79-0.95; P < .001) and high reliability (Cronbach alpha coefficient ranging between 0.78 and 0.94). Confirmatory factor analysis revealed adequate model fit, with comparative fit index of 0.853, goodness-of-fit of 0.947, and a 0.052 value of root mean squared error of approximation. CONCLUSIONS: The SMAQ-12-PT was found to be a valid and reliable instrument in the Portuguese population. Disease management representation for the specialty of periodontology and its impact on periodontal schedules and practices should be evaluated in future studies.

The Time Course of Information Processing During Eye Direction Perception.

Gaze directed at the observer (direct gaze) is a highly salient social signal. Despite the existence of a preferential orientation toward direct gaze, none of the studies carried out so far seem to have explicitly studied the time course of information processing during gaze direction judgment. In an eye direction judgment task, participants were presented with a sketch of a face. A temporal asynchrony was introduced between the presentation of the eyes and that of the rest of the face. Indeed, the face could be presented before the eyes, the eyes could be presented before the face, or the face and the eyes could be presented simultaneously. In a second time, the face direction was also manipulated. The results suggest that the time course of information processing during eye direction judgment follows a continuum that makes it possible to perceive the eyes first and then to use the facial context to judge the direction of gaze. Furthermore, the congruency between the direction of gaze and that of the face confirms this observation. Although these results are discussed in the light of existing theories about the mechanisms underlying gaze processing, our data provide new information suggesting that, despite their power to capture attention, the eyes probably have to stand out from a more general spatial configuration (i.e., the face) in order for their direction to be adequately processed.
