Validity and reliability of the generalized pliance and tracking 2-way scale: GPT-2s

This study developed and examined the validity and reliability of a scale that simultaneously measures generalized pliance and tracking with more focus on actions in daily situations. The so-called Generalized Pliance and Tracking 2-way Scale: GPT-2s comprises 16 items (8 items each for generalized pliance and tracking). In Study 1, an online survey was conducted among 1500 Japanese individuals (420 men, 1054 women, 26 others mean age = 29.47 years, SD = 10.89). We confirmed no violation of unidimensionality in the generalized pliance and generalized tracking factors by item response theory. Internal consistency was measured with Cronbach’s α =.80 for the generalized pliance factor and .84 for the tracking factor. Test–retest reliability was also assessed with intraclass correlation (1,1) = .61, 95 % CI .55, .67 for generalized pliance and intraclass correlation (1,1) = .56, 95 % CI .49, .62 for tracking. Regarding convergent validity, the generalized pliance score had a moderately negative correlation with the autonomy factor on the psychological well-being scale ( r = −.42). Conversely, the generalized tracking score had moderately positive correlations with the clarification of value and commitment ( r = .43) and the overall psychological well-being scale score ( r = .48). Furthermore, generalized tracking scores were higher in the healthy group. In Study 2, generalized pliance score showed positive correlation with the Generalized Pliance Questionnaire ( r = .43) and generalized tracking score showed positive correlation with the Generalized Tracking Questionnaire ( r = .54). Finally, we discussed the usefulness and limitations of the GPT-2s. • This study developed a measure of generalized pliance and tracking in daily situations (GPT-2s). • The study examined the validity and reliability of the GPT-2s's 16 items. • GPT-2s-Generalized pliance scores were higher in the non-healthy group. • GPT-2s-Generalized tracking scores were higher in the healthy group.
