The construct validity of the Toronto Alexithymia Scale (TAS) was tested by correlations with the Patient Self-Disclosure instrument and the Private Self-Consciousness scale in a study of 333 students at a large midwestern university. The TAS was found to be internally consistent and to yield a replicable factor structure. Scores on the TAS correlated negatively with both overall ratings of the importance of such disclosure and scores on the PSC, and positively with perceived difficulty of patient self-disclosure. Results support construct validity of the TAS and suggest a more generally restrictive communicative style among alexithymic individuals than previously thought.

Hand hygiene has been empirically proven to prevent cross-transmission of infection, which has led to the development of global guidelines such as the World Health Organization’s ‘My 5 Moments for Hand Hygiene.’ Because of the relatively recent launch of these guidelines (2009) technology designed to assist in measuring hand hygiene compliance appears not to fully acknowledge the influence of the WHO 5 Moments for hand hygiene Consequently, they may not be fit for purpose (FFP). This paper uses a review of the literature on current hand hygiene technology to assess the extent to which these are FFP based on these global guidelines. The results show that there are a variety of technologies available to assist with the monitoring and measurement of hand hygiene levels. However, none appear to explicitly achieve detection of all WHO 5 Moments for hand hygiene, limiting their effectiveness. The authors conclude that a systems approach offers a potential aid for developers aspiring to meet domain specific FFP requirements. Human factors may help guide such developments to meet user and context specific needs.

Four studies in which a patient self-disclosure questionnaire was developed and tested are reported. The instrument was designed to include only content judged by both patients and clinicians as important. Three areas of patient difficulty in disclosing to a health care provider were measured: personal problems and feelings, responses to health care, and life style. Patient difficulty in disclosure was assessed by 21 7-point rating scales, 7 for each disclosure area; ratings were summed to obtain scores. A correlation matrix of the ratings of 216 patients was subjected to a three-factor principal components analysis with varimax rotation; the solution accounted for 59% of the total variance. High internal consistency and test re-test reliability for the total scale and subscales were obtained; Cronbach's alpha .82-.83, n = 214; r = .81-.87, n = 66. In separate tests of construct validity patient self-disclosure was shown to be influenced by locus of control and perception of clinician empathy, and to covary with heart rate changes.
