This question is from Exercise 12 Questions to Be Graded in Statistics for Nursing Research 2nd Edition, A Workbook for Evidence-Based Practice (Grove & Cipher). Are you able to help?

Lindseth et al. (2014, p. 187) conducted a quasi-experimental study to examine the effects of low- and high-aspartame diets on depression, mood (irritability), working memory, and spatial orientation. These variables were measured at the interval or ratio level. “The participants served as their own control.” What statistical technique did Lindseth et al. conduct to analyze the data for the four dependent variables? Provide a rationale for your answer.

As no data is provided in the question, so in this regard, I shall explain you a process the can help you to perform the analysis...

You can perform a Multiple Regression Analysis in this regard...

Here, the variables can be as follows:

1) Independent Variables: Mood (irritability), Working Memory, and Spatial Orientation.

2) Dependent Variable: Data on Aspartame Diets...

Later on, you will get an equation of type:

Y = C + β₁M + β₂W + β₃S

Where,

β₁, β₂ and β₃ are the respective coefficients and Y represents the "Aspartame Diets"

M, W and S represents Mood (irritability), Working Memory, and Spatial Orientation.

This equation can be used to analyse the effect of one variable on the other i.e. if one increases/decreases, how the dependent variable behaves...

Kindly note that the value of R₂ is an important factor in Regression. normally it should be close to 1 or more than 0.75 (75%). it describes how much variations in the dependent variable is explained by the independent variables. A value more than 0.75 represents a good fit. Normally it depends on the variables that you are trying to analyse...

In regards to this question, kindly provide the data set so that we can perform the analysis for you. without a data set the analysis is not possible. The data set is missing in the question...

Statistics for Nursing Research 3rd edition Grove and Cipher A randomized experimental study examined the impact of a special type of vocational rehabilitation on employment variables among spinal-cord injured veterans, in which post-treatment wages and hours worked were examined (Ottomanelli, Goetz, Suris, McGeough, Sinnott, Toscano, Barnett, Cipher, Lind, Dixon, Holmes, Kerrigan, & Thomas, 2012). Participants were randomized to receive supported employment or treatment as usual (“Control”). Supported employment refers to a type of specialized interdisciplinary vocational rehabilitation designed to help...
