QUESTION: Newman et al. (2019) wanted to examine if the four items reflected a single unitary dimension of nostalgia or multiple dimensions of nostalgia. Which statistical analysis would be best for helping Newman et al. (2019) examine the dimensionality of their measure? Examine PINE Scale Dimensionality

Examine PINE Scale Dimensionality

A type of statistical analysis called factor analysis can be used for investigating the dimension of the Personal Inventory of Nostalgic Experiences scale (PINE). A statistical technique known as factor analysis can help identify the structure behind a set of variables. Component analysis can be used to determine if each of the items on the PINE-scale represents a unitary nostalgia dimension or multiple dimensions. Newman and colleagues. Newman et al. (2019) first need to gather data from individuals who completed the PINE Scale. Then they will have to use factor analysis to analyze the data they have gathered. One could use a number of statistical techniques to determine the PINE scale’s dimensionality, such as exploratory or confirmatory factor analysis.
