Fear of childbirth (FOC) is an important women's health issue. The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) is currently the most frequently used instrument to measure FOC. The scale is designed to measure different aspects of FOC but is conceptualized as a uni-dimensional instrument. Our aim was to investigate the underlying factor structure of the W-DEQ version A. A total of 1642 women scheduled to give birth at Akershus University Hospital (Norway) during 2009 and 2010 completed the W-DEQ in the third trimester. Validity and reliability were estimated by means of exploratory and confirmatory factor analyses and correlations with other relevant variables. Results confirmed a multidimensional structure of the W-DEQ. Six factors were identified, each measuring different domains: 'Fear', 'Negative appraisal', 'Loneliness', 'Lack of self-efficacy', 'Lack of positive anticipation', and 'Concerns for the child'. The final model resulted in a 25-item version of the instrument with adequate psychometric properties. Subfactors correlated differently with several relevant variables. Especially the factor 'Fear' was highly correlated with both the overall W-DEQ and several important outcomes. Future studies could examine whether this factor may serve as a good proxy for the full W-DEQ version A.

Factorial Design02:01

Factorial Design

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...
Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:
Self-Discrepancy Theory02:45

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
Factors Affecting Perception01:25

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...
