Depressive symptoms impact health-promoting lifestyle behaviors and quality of life in healthy women.

Background: Depressive symptoms are an independent risk factor of cardiovascular disease (CVD). More than 15% of persons with CVD have depressive symptoms, which are twice as likely to occur in women. Depressive symptoms in women being screened for CVD have not been well studied.

A psychometric toolbox for testing validity and reliability.

Purpose: To review the concepts of reliability and validity, provide examples of how the concepts have been used in nursing research, provide guidance for improving the psychometric soundness of instruments, and report suggestions from editors of nursing journals for incorporating psychometric data into manuscripts.

Methods: CINAHL, MEDLINE, and PsycINFO databases were searched using key words: validity, reliability, and psychometrics. Nursing research articles were eligible for inclusion if they were published in the last 5 years, quantitative methods were used, and statistical evidence of psychometric properties were reported.
