We developed a self-report measure of sensation seeking, a dispositional risk factor for various problem behaviors. In two studies, we administered the Brief Sensation Seeking Scale (BSSS) to more than 7000 adolescents. Study 1 participants completed a paper-and-pencil form of the BSSS in mass-testing sessions. Psychometric analyses of the resultant data revealed suitable item characteristics a...

PURPOSE The purpose of this report is to evaluate the reliability and validity of the five-item Evaluation to Sign Consent (ESC), a measure that can guide determination of an older adult's capacity to consent for research. DESIGN AND METHODS Information was obtained from 346 nursing home residents from six facilities who were being enrolled into a randomized controlled trial testing a restora...

Background Improving access to health and nursing care aims to maintain and promote the quality of life (Qol) of care recipients. Especially in dementia research, Qol is a major outcome. QUALIDEM is an often-used dementiaspecific Qol measure. It consists of two consecutive versions, one for mild to severe and one for very severe dementia. Previous results showed an insufficient interrater relia...

BACKGROUND Complicated grief, which is often under-recognized and under-treated, can lead to substantial impairment in functioning. The Brief Grief Questionnaire (BGQ) is a 5-item self-report or interview instrument for screening complicated grief. Although investigations with help-seeking samples suggest that the BGQ is valid and reliable, it has not been validated in a broader population. M...

in this paper a double-shaft turbofan engine is considered to be in the design phase. therefore its environmental condition and critical source of failures has been studied and the subsystems and components has been identified. since it is in design phase, the project encounters to the lack of specified failure data. to overcome this problem, the generic data or expert judgments on the basis of...

Despite the wide adoption of measures of executive functions and motivational tendencies in studies of developmental disorders and child psychopathology, few studies have investigated their test–retest reliability. The present paper examines the reliability of a new measure of delay aversion, three measures of working memory, a response inhibition measure and a measure of dual task performance....

Software engineers face a real probtem in guaranteeing that their computer programming systems under development will be able to function in a reliable manner and be easily understood, maintained and extended. A major impediment of this problem is coping with the inherent complexity of the software system in an effective way. The complexity of the computer system will defeat the designer's effo...

It is first pointed out that most often used reliability coefficient α and one-factor model based reliability ρ are seriously biased when unique factors are covariated. In the case, the α is no longer a lower bound of the true reliability. Use of Bollen’s formula (Bollen 1980) on reliability is highly recommended. A web-based program termed “STERA” is developed which can make stepwise reliabili...

OBJECTIVE The purpose of this study was to test reliability and validity of the Physical Resilience Scale. METHODS A single-group repeated measure design was used and 130 older adults from three different housing sites participated. Participants completed the Physical Resilience Scale, Hardy-Gill Resilience Scale, 14-item Resilience Scale, 5-item Geriatric Depression Scale, and the Yale Physi...
