Objective\ud \ud Excessive stress and poor coping skills can put university students at risk for mental health problems. The University Stress Scale (USS) provides a measure of both the categories of stress experienced by university students as well as the overall intensity of the stress experienced.\ud \ud Methods\ud \ud This study evaluated the psychometric properties of the USS and its clinical utility. Participants were a convenience cross-sectional sample of 2,596 Australian university students.\ud \ud Results\ud \ud Exploratory factor analysis provided support for a six-factor model comprising the categories of academic, relationships, equity, parenting, practical, and health. This structure was confirmed using confirmatory factor analysis. The measure had good discriminant and convergent validity and good internal consistency. A cut-off of 13 on the USS indicates students most likely to be experiencing depression and anxiety symptoms as a result of excessive stress. This study used a broad sample of Australian students; however, further replication is needed to confirm the utility of the measure for students in other countries.\ud \ud Conclusions\ud \ud The total stress score and the categorical breakdown of stressors makes the USS a useful, brief screening measure for clinicians working with university students

Background: The overuse of antibiotics is becoming an increasing concern. Antibiotic resistance, which increases both the burden of disease, and the cost of health services, is perhaps the most profound impact of antibiotics overuse. Attempts have been made to develop instruments to measure the psychosocial constructs underlying antibiotics use, however, none of these instruments have undergone thorough psychometric validation. This study evaluates the psychometric properties of the Parental Perceptions on Antibiotics (PAPA) scales. The PAPA scales attempt to measure the factors influencing parental use of antibiotics in children. Methods: 1111 parents of children younger than 12 years old were recruited from primary schools’ parental meetings in the Eastern Province of Saudi Arabia from September 2012 to January 2013. The structure of the PAPA instrument was validated using Confirmatory Factor Analysis (CFA) with measurement model fit evaluated using the raw and scaled χ ², Goodness of Fit Index, and Root Mean Square Error of Approximation. Results: A five-factor model was confirmed with the model showing good fit. Constructs in the model include: Knowledge and Beliefs, Behaviors, Sources of information, Adherence, and Awareness about antibiotics resistance. The instrument was shown to have good internal consistency, and good discriminant and convergent validity. Conclusion: The availability of an instrument able to measure the psychosocial factors underlying antibiotics usage allows the risk factors underlying antibiotic use and overuse to now be investigated.
