Mammography screening has been demonstrated to decrease mortality from breast cancer. Although adherence rates have increased, there is still a need to increase annual screening. Self-efficacy is a construct that has been found useful in predicting behaviors. Measurement of self-efficacy needs to be specific to the behavior and to have good validity and reliability. The purpose of this study is...

BACKGROUND AND OBJECTIVES Currently available tools to measure teamwork, an essential component of primary care, are generally very resource intensive and thus cannot be administered frequently. To explore the possibility of developing a brief teamwork-assessment instrument, we first administered 29 questions about teamwork from the Practice Environment Checklist (PEC) to all members of six cli...

technical principles to concrete research problems that appear in a wide variety of forms and with a myriad of obscuring features, details, and idiosyncracies. This article is based on a different approach: examination of a series of concrete research scenarios that we have encountered in our work as researchers, advisors to researchers, or reviewers. This article examines 26 real-world "case s...

On the basis of an empirical study of measures of constructs from the cognitive domain, the personality domain, and the domain of affective traits, the authors of this study examine the implications of transient measurement error for the measurement of frequently studied individual differences variables. The authors clarify relevant reliability concepts as they relate to transient error and pre...

Typically, when using existing scales, researchers conduct a confirmatory factor analysis and estimate reliability indices such as Cronbach alpha. Results are then used to select items that are subsequently incorporated in models. However, this process is inefficient as results from several studies consistently indicate that certain factors have low factor loadings. This study addressed this is...

Fifty years ago, L. J. Cronbach and P. E. Meehl (1955) advocated for the concept of construct validity, noting that psychologists study hypothetical, inferred entities and that validating measures of such entities involves basic theory testing. Three important developments in clinical assessment following that seminal article are noteworthy. First, clinical research has benefited from greater t...

Objective: this study aimed to carry of the cultural adaptation and to evaluate the reliability of the Compliance with Standard Precautions Scale (CSPS) for nurses in Brazil. Method: the adaptation process entailed translation, consensus among judges, back-translation, semantic validation and pretest. The reliability was evaluated by internal consistency (Cronbach alpha) and stability (test-r...
