“…In sum, as an initial validation study, our paper presented preliminary validity evidence supporting the use of the IPS in the Chinese context. The findings are in accordance with conclusions from studies that corroborated the psychometric soundness of the IPS in other countries (e.g., Svartdal et al, 2016 ; Svartdal, 2017 ; Guilera et al, 2018 ; Kim et al, 2020 ; Shaw and Zhang, 2021 ). At present, there has been accumulated evidence globally that suggests the utility of the IPS as a brief and valid scale for assessing procrastination.…”

“…In agreement with previous research (e.g., Steel, 2010;Rozental et al, 2014;Svartdal et al, 2016;Svartdal and Steel, 2017;Guilera et al, 2018), we found adequate internal consistency reliability of the nine-item scale within this sample. Regarding the dimensionality, the CFA results confirmed the one-factor structure of the IPS, which fit well with the original idea of the scale (as a unidimensional measure of irrational procrastination) put forward by Steel (2010Steel ( , 2002 as well as conclusions from prior validation studies in other languages and countries/regions (e.g., Svartdal et al, 2016;Svartdal, 2017;Kim et al, 2020;Shaw and Zhang, 2021). Furthermore, measurement invariance held across gender, demonstrating that the Chinese IPS was not biased against men or women and that any gender difference in the scale scores would be attributable to the underlying psychological construct itself.…”

The present paper reports on the preliminary validation of a Chinese version of Steel’s Irrational Procrastination Scale (IPS). To this end, the nine items of the IPS were translated into Chinese and data were collected from a sample of 2,361 mainland Chinese college students. Confirmatory factor analysis (CFA) was used to examine the dimensional structure of the IPS, and multigroup CFA (MG CFA) was carried out to evaluate the measurement invariance across gender. Results revealed that the Chinese IPS had adequate internal consistency reliability, adhered to the one-factor structure, and exhibited strong or scalar invariance across the two gender subgroups, thereby providing support for the internal construct validity of the scale. Additionally, the IPS scores were found to be strongly and negatively related to the Conscientiousness personality trait while showing weak correlations with the other traits, which provided some support for the convergent and divergent validity of the Chinese IPS. Study limitations and future research directions (e.g., expanding the empirical evidence for the scale’s criterion-related validity) are discussed.

“…The IPS is used to assess the changes from pre-to postscores. The IPS showed good internal consistency (Cronbach α=.91) [50] as well as a high level of reliability (r pm =0.58-0.74), and good content, structural, and substantive validity [51].…”

Background Academic procrastination is a widespread problem among college students. It is linked to poor academic performance and increased college dropout intentions, as well as several mental health problems such as depression, anxiety, and stress. Guided web-based interventions can help reduce procrastination. However, guidance by professional clinicians draws upon valuable and limited societal resources, and a more efficient, scalable form of guidance is needed. Guidance by trained clinical psychology students has not yet been examined. Objective The aim of this open trial is to examine the feasibility and acceptability of a web-based procrastination intervention for college students under the guidance of student digital coaches (e-coaches). Methods We developed a single-arm trial of a guided web-based intervention targeting procrastination for the Dutch student population. Guidance is delivered by trained clinical psychology students asynchronously in the form of textual feedback on intervention progress, with the aim of supporting and motivating the participant. Participants are recruited at 7 Dutch universities. Primary outcomes are intervention satisfaction, usability, and adherence, which are assessed by the Client Satisfaction Scale (CSQ-8), System Usability Scale (SUS-10), and number of completed modules, respectively. The primary outcomes will be examined by calculating descriptive statistics. Secondary outcomes are e-coach satisfaction and changes to procrastination, depression, stress, and quality of life from pre- to posttest and follow-up. Results The project was funded in 2019, and recruitment began in January 2021. As of May 2023, a total of 985 participants were enrolled, of which 372 had completed the posttest and 192 had completed the follow-up. The expected date of analysis and publication of the results is 2024. Conclusions The results are expected to contribute to the body of literature regarding eHealth in 3 ways. First, we will examine whether students who procrastinate adhere to and are satisfied with an eHealth intervention targeting this problem. Second, we will explore whether an intervention targeting procrastination can also decrease depression and stress. Lastly, we will investigate whether trained psychology students can effectively guide their peers in web-based interventions. Given the shortage of licensed psychologists, exploring alternative sources of guidance is much needed in order to provide students with the mental health support they need.

“…For academic stress, the Student-Life Stress Inventory-Revered (SLSI) proposed by Gadzella ( 2005) is used, subsequently producing a Cronbach alpha value of .93. Furthermore, the PWS (Psychological Well-Being Scale) and IPS (Irrational Procrastination Scale) proposed by Ryff (1989) and Shaw & Zhang (2021) are used for psychological well-being and procrastination, respectively. In this case, the development of these measuring instruments is thoroughly compiled, regarding the observed determinants.…”

This study aims to develop an instrument to determine students' academic performance. In this case, a quantitative design was used, with a random sampling technique utilized in selecting 415 students from the University of Muhammadiyah Malang. Data analysis was also carried out using Rasch Model. Based on the fit item criteria analysis, 5 misfit elements were each observed for the Mean and Standard Deviation logit and MNSQ (Mean Square) outfit. This indicated that the most difficult and easiest questions were numbers 47 and 10, respectively. For regional and school origins, the items containing differential function questions were 2 and 9, respectively. The reliability of the measuring instrument, item, and person was also 83, 98, and 79. In addition, only 7 of the 67 utilized items did not meet the required criteria and the remaining were completely accepted.
