Connectedness to nature represents the relationship of the self with the natural environment and has been operationalized using different scales. One of the most systematically studied in the Anglo-Saxon context is the Connectedness to Nature Scale (CNS). In an attempt to study the psychometric properties of this instrument in a French-speaking context, three studies (Study 1 n = 204, Study 2 n...

METHODS Secondary analysis of data from 131 neonates from the Maternal Opioid Treatment: Human Experimental Research (MOTHER) study, a randomized trial in opioid-dependent pregnant women administered buprenorph...

The scale development process is critical to building knowledge in human and social sciences. The present paper aimed (a) to provide a systematic review of the published literature regarding current practices of the scale development process, (b) to assess the main limitations reported by the authors in these processes, and (c) to provide a set of recommendations for best practices in future sc...

BACKGROUND Psychometric testing is used to identify patients with cirrhosis who have developed hepatic encephalopathy (HE). Most batteries consist of a series of paper-and-pencil tests, which are cumbersome for most clinicians. A modern, easy-to-use, computer-based battery would be a helpful clinical tool, given that in its minimal form, HE has an impact on both patients' quality of life and th...

AIM To review quantitative studies of safety climate in health care to examine the psychometric properties of the questionnaires designed to measure this construct. METHOD A systematic literature review was undertaken to study sample and questionnaire design characteristics (source, no of items, scale type), construct validity (content validity, factor structure and internal reliability, conc...

The Penn State Worry Questionnaire for Children (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997) is a 14-item self-report measure of worry in children and adolescents. Although the PSWQ-C has demonstrated favorable psychometric properties in small clinical and large community samples, this study represents the first psychometric evaluation of the PSWQ-C in a large clinical sample (N =...

There is a major need for an empirical evaluation of classification criteria for somatoform disorders. The present study analyzes psychometric properties of the existing criteria for somatization disorder. The full sample consisted of 324 patients seeking help because of "psychosomatic problems." Data from a subsample of carefully diagnosed patients with somatization syndrome (n = 76) and a cli...

Many new mothers discontinue breastfeeding prematurely due to difficulties encountered rather than maternal choice. Research has shown that a significant predictor of breastfeeding duration is maternal confidence. Using self-efficacy theory as a conceptual framework to measure breastfeeding confidence, the Breastfeeding Self-Efficacy Scale (BSES) was developed and psychometrically tested among ...
