“…Furthermore, there was a significant negative relationship between the scores of the PPS and the SWLS, suggesting that they measure contrasting constructs. This finding is consistent with prior research ( Rebetez et al, 2014 ; Svartdal, 2017 ; Svartdal and Steel, 2017 ; Kaneko et al, 2022 ). Finally, the correlations observed with the Big Five personality traits align with those reported in other studies ( van Eerde, 2003 ; Steel, 2007 ; Rebetez et al, 2014 ), which indicate that procrastination is strongly inversely related to conscientiousness.…”

“…Thus, in our study the low internal consistency value for the timeless / lateness dimension may be due to the lower variability of the scores on this factor and a lower average value with respect to the other factors in the Spanish culture. Moreover, internal consistency of the Spanish PPS total score is satisfactory, being similar to those reported by Svartdal et al (2016) (i.e., range over countries: 0.89–0.93), by Svartdal and Steel (2017) (i.e., 0.92) in the global worldwide study, by Zamirinejad et al (2022) (i.e., 0.94) in the Persian version, by Rocha et al (2021) (i.e., 0.91) in the Brazilian Portuguese version, and in the Japanese version by Kaneko et al (2022) (i.e., 0.92).…”

“…The assessment of temporal stability suggests from moderate (i.e., decisional delay and timeliness / lateness factors) to good (i.e., implemental delay factor) test-retest reliability coefficients. Results obtained in other adaptations have been higher as in the case of the Persian version ( Zamirinejad et al, 2022 ) where test-retest reliabilities were 0.81 ( decisional delay ), 0.80 ( implemental delay ), 0.79 ( timeliness / lateness ) or lower as the Japanese version ( Kaneko et al, 2022 ), where coefficients were 0.72, 0.62, and 0.54, respectively. For the PPS total score test-retest reliability obtained in this study was similar to that shown in the French version ( Rebetez et al, 2014 ) (i.e., 0.87), the Persian version ( Zamirinejad et al, 2022 ) (i.e., 0.88) and higher than that obtained in the Japanese version ( Kaneko et al, 2022 ) (i.e., 0.68).…”

“…Those 12 items that loaded into the first factor were subsequently included in the PPS, resulting in a measure of “pure” procrastination. The PPS is currently available in 12 languages, i.e., Arabic ( Besharat and Maserrat, 2019 ), Brazilian Portuguese ( Rocha et al, 2021 ), English ( Steel, 2010 ), Finnish ( Svartdal et al, 2016 ), French ( Rebetez et al, 2014 ), German ( Svartdal et al, 2016 ), Italian ( Svartdal et al, 2016 ), Japanese ( Kaneko et al, 2022 ), Korean ( Kim et al, 2020 ), Norwegian ( Svartdal, 2017 ), Persian ( Zamirinejad et al, 2022 ), Polish ( Svartdal et al, 2016 ), and Swedish ( Rozental et al, 2014 ). Furthermore, Díaz-Morales et al (2006) translated into Spanish the items of the three instruments upon which the PPS is based, which were subsequently employed in the studies conducted by Codina et al (2018 , 2020) and Valenzuela et al (2020) .…”

The objective of the current study was to adapt and validate the pure procrastination scale (PPS) for the Spanish adult population. Procrastination can have numerous consequences in daily life, making it essential to have reliable and valid instruments for measuring procrastination. Thus, this study was conducted to address this need. The sample consisted of 596 adults aged 18–83 years (M = 35.25, SD = 13.75). In addition to the PPS, participants completed two procrastination measures, namely the irrational procrastination scale and the decisional procrastination questionnaire, alongside the Big Five inventory and the satisfaction with life scale. The results of the confirmatory factor analysis revealed a three-factor structure of the PPS. The examination of the reliability of scores in terms of internal consistency and temporal stability showed satisfactory results for the PPS scores. Moreover, gender invariance was observed at the scalar level. Finally, the PPS scores correlated with other measures of procrastination, personality traits, and satisfaction with life in the expected direction and magnitude. In conclusion, the Spanish PPS offers valid and reliable scores when administered to adult population.

“…The pure procrastination scale [ 25 ] was used to confirm the validity of the BPS. We used the Japanese version of this scale [ 26 ]; a 5-point scale ranging from 1 (not at all) to 5 (always), with 12 items to assess general procrastination. Cronbach’s α and ω coefficients were 0.94 and 0.95, respectively.…”

Bedtime procrastination (BP) is prevalent and problematic, with no previous study conducted in Japan. This study developed the Japanese version of the Bedtime Procrastination Scale (BPS), assessed its validity, and investigated the relationship between BP, demographic features, and sleep outcomes. Participants were divided into two samples (N = 252 and N = 630). Sample 1 involved a longitudinal study to confirm test–retest reliability of the BPS. Sample 2 involved a cross-sectional study to assess confirmatory factor analysis, criterion-related validity, construct validity, and determine the internal consistency of the BPS. The relationship between BP and demographic features (gender, age, and employment status) and sleep outcomes (Athens Insomnia Scale, sleep hours, sleep onset latency, and sleep efficiency) was investigated using Sample 2. The BPS showed good internal consistency (Cronbach’s α coefficients = .90–91), test–retest reliability (ICC = .86), and one factor model was valid; CFI = .95, TLI = .94, RMSEA = .10, and SRMR = .04. The BPS had a moderate positive association with general procrastination, moderate negative associations with self-control, sleep quality, and sleep duration on weekdays, and those who answered “yes” to the item “Do you have trouble with bedtime procrastination?” had higher BPS scores. BPS scores were moderately higher for younger participants (≤ 40 years), slightly higher for females, and non-significantly different between employment statuses. The BPS showed a significant positive correlation with insomnia symptoms, weak positive association with sleep efficiency on weekdays and holidays, and no significant association with sleep onset latencies on holidays and weekdays. This study provides new data on demographic predictors of BP in Japan. No clear effects of gender and employment status were found, but age was a strong predictor of BP, where younger age groups had a higher BP risk.

Future optimism group based on the chronological stress view is less likely to be severe procrastinators

Previous studies have shown that procrastinators tend to disregard the future. However, the "time view" of procrastinators, including their impressions of the future, has not been sufficiently examined. Therefore, we introduced new indices, "chronological stress view" and "chronological well-being view," which treat impressions of the past, present, and future (= time view) as time-series data via stress and well-being, respectively. The results showed that the group that believed that stress did not increase as they moved into the future had a lower percentage of severe procrastinators. No relationship was found between the chronological well-being view and procrastination. This result suggests that people who are relatively optimistic about the future based on the chronological stress view are less likely to be severe procrastinators. This may suggest the importance of having a hopeful prospect in the future to avoid procrastinating on actions that should yield greater rewards in the future.
