Descriptive analysis of the data was calculated in IBM SPSS Statistics (Version 27) predictive analytics software. Descriptive statistics calculated the measures of central tendency including mean, median, mode and standard deviation. This study did not include any reverse scoring of data. Reverse scoring was built into the algorithm formula by the author of the survey, which is: (2((know + acc + stim/3)) + iden -((intro + reg/2) + 2amo), (Vallerand et al., 1992).

Validity describes how accurately an instrument measures what it is supposed to measure. The AMS-C 28 (Vallerand et al., 1992) was designed to measure academic motivation within the construct of self-determination theory (Ryan & Deci, 2000). A Cronbach alpha test was done in Vallerand’s (1992) initial analysis of the AMS-C 28 to assess th
Validity describes how accurately an instrument measures what it is supposed to measure. The AMS-C 28 (Vallerand et al., 1992) was designed to measure academic motivation within the construct of self-determination theory (Ryan & Deci, 2000). A Cronbach alpha test was done in Vallerand’s (1992) initial analysis of the AMS-C 28 to assess the internal consistency and reliability of the study questionnaire and its sub-scales. Validity and reliability evidence obtained show that internal consistency was reported for all seven sub-scales within the constructs of intrinsic motivation, extrinsic motivation, and amotivation. Validity data shows the following: Cronbach’s alpha = 0.81, min = 0.62, max = 0.91, (Vallerand et al., 1992, as cited in Rand, 2018). In this study, Cronbach’s alpha was calculated at = 0.92 for all 28 questions, and = 0.84 for each of the 7 sub-scales, which are excellent (0.92-0.94), and reliable (0.84-0.90) respectively (Taber, 2018).

AMS Reliability
Reliability measures the consistency of an instrument. This means that each time an instrument is used it will provide consistent results. The AMS-C 28 (Vallerand et al., 1992) has been used in many research studies in the United States and internationally. The AMS-C 28 survey has been used in prior research to explore self-determinat
Reliability measures the consistency of an instrument. This means that each time an instrument is used it will provide consistent results. The AMS-C 28 (Vallerand et al., 1992) has been used in many research studies in the United States and internationally. The AMS-C 28 survey has been used in prior research to explore self-determination motivation levels for many groups of college students in the United States (Anderson et al., 2018; Fallon, 2019; Walker, 2019), and in Pakistan (Javaeed et al., 2019), and Slovenia (Levpušček & Podlesek, 2017). The validity and reliability of the AMS-C 28 since its creation in 1992 remains consistent throughout many research studies (Anderson et al., 2018; Fallon, 2019; Levpušček & Podlesek, 2017; Miulescu, 2018; Ramos, 2019; Walker, 2019).
