PURPOSE The purpose of this study was to review articles related to the psychometric properties of the Perceived Stress Scale (PSS). METHODS Systematic literature searches of computerized databases were performed to identify articles on psychometric evaluation of the PSS. RESULTS The search finally identified 19 articles. Internal consistency reliability, factorial validity, and hypothesis ...

Historically, the measurement of market orientation has proved to be difficult, due to the low external validity of the concept. Existing scales exhibit acceptable properties in measuring market orientation in business organizations, but are less accurate in the context of higher education institutions. This paper compares the performance of three scales – the MARKOR scale, the MKTOR scale, and...

Social and medical scientists are often concerned that the external validity of experimental results may be compromised because of heterogeneous treatment effects. If a treatment has different effects on those who would choose to take it and those who would not, the average treatment effect estimated in a standard randomized controlled trial (RCT) may give a misleading picture of its overall im...

This study was aimed to validate the Italian version of the Children’s Coping Strategies Checklist-Revision1 (CCSC-R1; Ayers & Sandler, 1999). Seven hundred and forty-seven youngsters (50.5% boys) from two age groups (children: aged 9-10; early adolescents: aged 11-14) participated in the study. Dimensionality of the CCSC-R1 was explored by means of confirmatory factor analyses and testing alte...

It is crucial to reduce in...

We design a laboratory experiment to illuminate the channels through which relatively more attractive individuals receive higher wages. Specifically, we are able to distinguish taste-based discrimination from rational statistical discrimination and biased beliefs. Using three realistic worker tasks to increase the external validity of our results, we find that the “beauty premium” is highly tas...

The aim was to critically appraise the methodological quality of studies and determine the psychometric qualities of Past-week and Usual-week Physical Activity Questionnaires (PAQs). Data sources were obtained from Pubmed and Embase. The eligibility criteria for selecting studies included: 1) at least one psychometric property of PAQs was examined in adults; 2) the PAQs either had a recall peri...

One of the goals of psychological assessment focuses on the adaptation of its instruments to different populations. The objective of this study is to establish the psychometric properties and dimensional structure of the Spanish version of the Coping Responses Inventory-Adult Form (CRI-Adult, Moos, 1993). The following criteria were analyzed: a) descriptive statistics; b) internal consistency r...

BACKGROUND Google Street View provides a valuable and efficient alternative to observe the physical environment compared to on-site fieldwork. However, studies on the use, reliability and validity of Google Street View in a cycling-to-school context are lacking. We aimed to study the intra-, inter-rater reliability and criterion validity of EGA-Cycling (Environmental Google Street View Based Au...

We conduct a randomized field experiment with a Yale service club and find that the promise of public recognition increases giving. Some may claim that they give when offered public recognition in order to motivate others to give too, rather than for the more obvious expected private gain from increasing one’s social standing. To tease apart these two theories, we also conduct a laboratory expe...
