Abstract

Procrastination, the habitual delaying of tasks, has long been considered to negatively affect procrastinators. Chu and Choi (2005), however, have newly recognized active procrastination, a form that has positive effects on procrastinators. This study aims to validate the use of the Active Procrastination Scale (APS) in bahasa Indonesia. In this validation, 239 undergraduate students completed online questionnaires consisting of the APS and other measurements (GPA, Pure Procrastination Scale (PPS), Academic Motivation Scale (AMS), and International Personality Item Pool (IPIP-50 item) in Indonesian. The data was analyzed using confirmatory factor analysis (CFA), exploratory factor analysis (EFA), reliability analysis, intra-correlation analysis, and correlation analysis with other criteria. Both CFA and EFA revealed that all items matched the same factors as Choi and Moran (2009)’s original design (RMSEA ≤ 0.08, GFI ≥ 0.9, CR ≥ 0.7, AVE ≥ 0.5). In addition, all dimensions were reliable (CITC ≥ 0.3, α ≥ 0.6). Meanwhile, intra-correlation analysis indicated that each dimension correlated with all others, in keeping with previous findings. The same findings were also found in correlation analysis. Each dimension showed the same correlation patterns with other criteria as the prior findings. In conclusion, the APS-Bahasa Indonesia is a valid procrastination measurement.

Abstract

Validity evidence based on internal structure is important for psychological measurements and this internal structure can be evaluated by factor analysis. Two types of factor analysis are often conducted on psychometric tests: confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). This study compared the groupings of the 30-item Indonesian version of the Academic Motivation Scale(AMS–Bahasa Indonesia), using both CFA and EFA. The CFA of the data sample from 1,168 undergraduates indicated that all dimensions and sub dimensions of the AMS–Bahasa Indonesia had good internal structural validity. Each subdimension, dimension, and variable of the AMS–Bahasa Indonesia fulfilled the goodness of fit criteria (RMSEA ? 0.08; GFI ? 0.9; CR ? 0.7). The EFA showed that all items of the three dimensions grouped perfectly as designed by Vallerand et al. (1992), and the factor loading values of all items are greater than or equal to 0.4. Although there are cross loadings of items, it can be explained as why it occurs. The results of the internal consistency analysis showed that the AMS–Bahasa Indonesia is a reliable measurement (? ? 0.7). In conclusion the AMS–Bahasa Indonesia is a valid instrument for measuring academic motivation accurately and reliably.

Abstract

This study examines the validity and reliability of the Indonesian version of the Career Planning Questionnaire (CPQ) for high school students using the Rasch Model. Data were collected via a non-random sampling survey involving 209 respondents. Analysis was conducted using Winsteps software to evaluate item quality and model fit. Results indicate that the three CPQ subscales self-knowledge, occupational knowledge, and career decision-making skills met unidimensionality criteria, with raw variance explained values of 48.1%, 42.6%, and 50.0%, respectively. Item reliability was high (0.97 for subscale A, 0.99 for B, and 0.73 for C), while person reliability was moderate (0.70, 0.42, and 0.83). Differential Item Functioning (DIF) analysis identified two gender-biased items (A16 and C20). Additionally, Mixture Rasch Model analysis revealed two latent classes, reflecting response heterogeneity among students. These findings demonstrate that the Indonesian CPQ is a valid and reliable tool for assessing high school students’ career planning, though some items require revision to enhance measurement accuracy and fairness.
