No current instrument assesses women's health locus of control beliefs in relation to childbirth. Form C of the Multidimensional Health Locus of Control Scales was used to develop items for a new instrument specific to labor and delivery (MHLC-LD). Psychometric analyses conducted with two independent samples of pregnant women supported a three-factor model of the new instrument, consisting of Internal, Powerful Others, and Chance subscales. Results revealed modest coefficient alphas (>.70) for the subscales and demonstrated construct validity in known group analyses. Future validation research will focus on improving the internal consistency reliability of the MHLC-LD, testing factorial invariance across demographic groups, and examining the relationships between obstetric risk, previous birth experiences, and beliefs about control over childbirth outcomes.

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results from...

Formulating and Validating Nursing Diagnosis II

Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.
Risk nursing diagnoses represent clinical judgments of an individual, family, or community more vulnerable to developing the health problem than others...

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
