In this article, I review Psychological Statistics and Psychometrics Using Stata, by Scott A. Baldwin (2019, Stata Press).

We present and develop the notion of ‘universal psychometrics’ as a subject of study, and eventually a discipline, that focusses on the measurement of cognitive abilities for the machine kingdom, which comprises any kind of individual or collective, either artificial, biological or hybrid. Universal psychometrics can be built, of course, upon the experience, techniques and methodologies from (h...

We present and develop the notion of ‘universal psychometrics’ as a subject of study, and eventually a discipline, that focusses on the measurement of cognitive abilities for the machine kingdom, which comprises any (cognitive) system, individual or collective, either artificial, biological or hybrid. Universal psychometrics can be built, of course, upon the experience, techniques and methodolo...

Psychometrics is a well-developed field in psychology, and usability researchers began to use psychometric methods to develop and evaluate questionnaires to assess usability a little over ten years ago (Sweeney & Dillon, 1987). The goal of psychometrics is to establish the quality of psychological measures (Nunnally, 1978). Is a measure reliable (consistent)? Given a reliable measure, is it val...

Advances in computational psychometrics and mathematical methods have been gaining a significant role in both medicine and psychology over these past years. The mainstream in psychometrics is moving towards ever greater use of computational and mathematical modeling techniques. Such techniques are critical in the emerging fields of affective and wearable computing, where new biomedical instrume...

Although the Beck Depression Inventory (BDI) is commonly used to assess levels of depressive symptoms in socially anxious adults, its psychometric properties in this context have never been formally examined. Therefore, we examined the psychometrics of the BDI in a sample of adults with a principal diagnosis of social anxiety disorder (N = 113). The BDI exhibited good internal consistency and r...

Background: Safety climate assessment is increasingly recognized as an important factor in healthcare quality improvement, especially in operating rooms (OR). One of the most commonly used and rigorously validated tools to measure safety culture is the Safety Attitudes Questionnaire (SAQ). This study presents the validation of the Operating Room Version of the SAQ (SAQ-OR) for use in Portuguese...
