Common methods used in the literature to identify factors within exploratory factor analysis has been shown to be potentially problematic. This brief report illustrates a state of the art approach in identifying factor structure by adding parallel analysis prior to exploratory factor analysis. Parallel analysis enables researchers to have a high degree of confidence of the number of factors to extract prior to exploratory factor analysis. The procedure is illustrated by using items from the National Survey of Families and Households (NSFH) that were used to identify relationship scales.

Negative symptoms are associated with a range of poor clinical outcomes, and currently available treatments generally do not produce a clinically meaningful response. Limited treatment progress may be...
High levels of trait impulsivity are considered a risk factor for substance abuse and drug addiction. We recently found that non-planning trait impulsivity was negatively correlated with post-commissu...
Dimensional structure, psychometric properties, and sex invariance of a Bahasa Malaysia (Malay) translation of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) in Malaysian Malay adults.
The 34-item Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) is a widely-used measure of multidimensional body image. Here, we examined the psychometric properties of a ...
This study investigated the psychometric properties of the Italian version of a French scale to detect attitudes toward same-sex parenting. The Italian sample was split into two subsamples. On one, ex...

Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
A set of statistical methods for analyzing the correlations among several variables in order to estimate the number of fundamental dimensions that underlie the observed data and to describe and measure those dimensions. It is used frequently in the development of scoring systems for rating scales and questionnaires.
Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)
A neurobehavioral syndrome associated with bilateral medial temporal lobe dysfunction. Clinical manifestations include oral exploratory behavior; tactile exploratory behavior; hypersexuality; BULIMIA; MEMORY DISORDERS; placidity; and an inability to recognize objects or faces. This disorder may result from a variety of conditions, including CRANIOCEREBRAL TRAUMA; infections; ALZHEIMER DISEASE; PICK DISEASE OF THE BRAIN; and CEREBROVASCULAR DISORDERS.
Prospective risk assessment tool aimed at identifying potential risks and their impact in healthcare settings.
Standard antiretroviral therapy (ART) consists of the combination of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering whe...
