SPSS Homework: Validity

Overview

Beginning with the data set from SPSS Homework: Reliability, you will conduct further analyses to gather validity evidence for the Grit Scale (Duckworth, Peterson, Matthews, & Kelly, 2007).

First, we need to create subscale scores for the BFI subscales (Goldberg, 1992). You should have both raw item responses and reverse-scored responses for the appropriate items. Sum the item responses for the subscale items substituting the reverse-scored items for those that needed reverse-scoring.For example, let us say you named your reverse-score Extraversion items as "E2r" that flipped the responses for "E2". Your total score for Extraversion should be the sum of the following items: E1, E2r, E3, E4r, E5, E6r, E7, E8r, E9, E10r. Just sum total score, do not divide.To save some typing, I have included the code you will need in SPSS:

Subscale	Code
Extraversion	SUM(E1,E2r,E3,E4r,E5,E6r,E7,E8r,E9,E10r)
Neuroticism	SUM(N1,N2r,N3,N4r,N5,N6,N7,N8,N9,N10)
Agreeableness	SUM(A1r,A2,A3r,A4,A5r,A6,A7r,A8,A9,A10)
Conscientiousness	SUM(C1,C2r,C3,C4r,C5,C6r,C7,C8r,C9,C10)
Openness	SUM(O1,O2r,O3,O4r,O5,O6r,O7,O8,O9,O10)

Instructions

For this homework, you will:

A. Create BFI subscale totals. As described above, sum the responses to the 10 BFI items per subscale substituting the reverse-scores BFI items where appropriate. Calculate a mean and standard deviation (SD) for each subscaleand creates an APA-formatted table including sample size (n), mean, and SD.

B. Correlate the Grit Scale total with each BFI subscale total scores. Create an APA-formatted table in Word that displays the sample size (n), correlation (r), and p-value for each of the five correlations.

C. Read Duckworth et al. (2007) article. Focus on the correlations they found between the Grit Scale and the BFI subscales.

D. Write a verbal summary discussing the results of your validity analyses. This summary section will include 2 elements:

1. Summarize the results of your validity analysis. How do they compare to the ones found by Duckworth (2007)? Do yours look like the one from their study?

2. Interpret the values that you found from the analyses. Do the correlations you found make theoretical sense? Provide one idea of another analysis that could provide validity evidence for the Grit Scale (see pages205-206 in Cohen, Schneider, & Tobin, 2022).
