Abstract

The increasing incidence of crime and violence among university students highlights the importance of understanding dark personality traits within social, educational, and workplace contexts. Dark personality traits including Machiavellianism, Narcissism, Psychopathy, and Sadism—play a significant role in interpersonal dynamics, decision-making, and individual adaptation strategies. This study aims to validate the Indonesian version of The Short Dark Tetrad (SD4) scale. A total of 305 students from various faculties at the University of Surabaya participated in this study, selected through purposive sampling. Data were analyzed using Principal Component Analysis (PCA) to assess structural validity and Cronbach’s Alpha to determine reliability. The results indicate that the Indonesian version of SD4 demonstrates adequate internal structural validity, with reliability coefficients ranging from 0.621 to 0.752. These findings suggest that SD4 is a valid and reliable instrument for identifying dark personality traits among Indonesian university students. The implications of this study support the use of SD4 in both academic and practical settings, particularly for psychological assessment and character development in higher education environments.

Abstract

This study aims to analyze employee engagement from a multidimensional perspective by differentiating three forms of employee engagement expression: Convey (speaking positively about the organization), Commit (desire to stay), and Contribute (effort to provide maximum contribution). The data were collected from 1,235 employees across various sectors in Indonesia through the Employee Experience Survey (EES) developed by KTM Consulting, using a population study. The research population comes from various industry sectors and job backgrounds, ranging from staff to managerial levels, thus adequately reflecting the diversity of organizational contexts in Indonesia. This study employed independent sample t-tests to examine differences in engagement scores across demographic groups and multiple linear regression analysis to identify the contribution of each cluster to engagement expressions, using a significance level of p ≤ 0.05. The results indicate that each form of engagement is influenced by different driving factors: Brand & Reputation has a significant impact on Convey (45.15%), Career Development & Growth Opportunities primarily influences Commit (21.58%), and Purpose & Meaning serves as the main driver for Contribute (30.84%). These findings underscore that a one-dimensional approach to measuring engagement risks overlooking the psychological dynamics underlying the employee-organization relationship. By understanding engagement expressions separately, organizations can design more precise, relevant, and long-term interventions to enhance work motivation, retention, and employee contribution.

Abstract

Neuroticism is a part of the human personality which consists of several negative emotions. The level of neuroticism has a tendency to become unstable, when individuals are faced with a traumatic event, including when the COVID-19 pandemic hit. In order to obtain a more in-depth picture of the fluctuation level of neuroticism (negative emotions), this study measured neuroticism score utilizing the Big Five Inventory-2 (BFI-2) on 1,911 subjects in the age range of 18-25 years. This measurement was carried out longitudinally, with details of measurements on four timelines. All data collection process was carried out by accidental random sampling. This study proves that there is fluctuating trend in each aspect of neuroticism. The aspects of anxiety and neuroticism have a decreasing trend, the aspect of depression has an increasing trend, and the aspect of emotional volatility has a stable trend. The occurrence of these fluctuations proves that COVID-19 affects life aspects of most individuals. Neuroticism merupakan bagian dari kepribadian manusia yang terdiri atas sejumlah emosi negatif. Tingkat neuroticism memiliki kecenderungan untuk berubah menjadi tidak stabil, ketika individu dihadapkan pada sebuah peristiwa traumatis, tidak terkecuali ketika pandemi COVID-19. Guna memperoleh gambaran yang lebih mendalam mengenai tingkat fluktuasi neuroticism (emosi negatif) tersebut, studi ini mengukur skor neuroticism menggunakan Big Five Inventory-2 (BFI-2) pada 1.911 subjek pada rentang usia 18-25 tahun. Pengukuran ini dilakukan secara longitudinal, dengan rincian pengukuran pada empat lini masa. Seluruh proses pengumpulan data dilakukan dengan accidental random sampling. Studi ini membuktikan bahwa terdapat tren fluktuasi pada tiap aspek neuroticism. Aspek anxiety dan neuroticism memiliki tren menurun, aspek depression memiliki tren meningkat, dan aspek emotional volatility memiliki tren stabil. Terjadinya fluktuasi ini membuktikan bahwa COVID-19 memengaruhi aspek kehidupan sebagian besar individu.

Abstract

The aim of this study was to find out whether anxiety caused by tasks affect college student procrastination behavior, while applying the Temporal Motivation Theory (TMT) (Steel, 2007). A non-randomized pretest-posttest control group design was conducted with subjects who were every college student of the even semester of the 2011/2012 generation who were taking the Measurement Instrument Construction subject. In order to measure the procrastination levels, this study used Pure Procrastination Scale (PPS) and the time to hand-in the tasks, while in order to measure the anxiety levels, this study used a scale consisting of 22 items. Research results showed that there was a correlation between anxiety and academic procrastination (r = .417; p = .000). The experiment group revealed that subjects with high anxiety levels chose to immediately work on a task, while subjects with high anxiety levels in the control group chose to procrastinate. Tujuan studi ini adalah untuk mengetahui apakah kecemasan yang ditimbulkan oleh tugas berpengaruh pada perilaku prokrastinasi mahasiswa tersebut dengan menggunakan Temporal Motivation Theory (TMT) (Steel, 2007). Suatu desain kelompok kontrol pretes-pasca-tes dikenakan pada semua mahasiswa yang sedang mengambil mata kuliah Penyusunan Alat Ukur pada semester genap tahun ajaran 2011/2012. Penelitian ini menggunakan Pure Procrastination Scale (PPS) dan jam pengumpulan tugas untuk mengukur tingkat prokrastinasinya, sedangkan untuk kecemasan digunakan skala yang terdiri atas 22 butir pernyataan. Hasil studi ini menunjukkan bahwa ada hubungan antara kecemasan dan prokrastinasi akademik (r = .417 ; p = .000). Pada kelompok eksperimen seseorang yang cemas lebih memilih untuk segera mengerjakan tugasnya, sedangkan pada kelompok kontrol terbukti seseorang yang cemas lebih memilih untuk melakukan penundaan.

Abstract

This experimental study examined whether Chinese zodiac personality descriptions, when used as priming stimuli, affect logical thinking ability among Generation Z students. A 2x2 factorial design (valence x validity) was applied to 105 college students aged 18-25, who were randomly assigned to one of four groups: positive-valid, positive-invalid, negative-valid, or negative-invalid. Logical thinking was measured using 15-minute Sudoku Logical Task administered before and after priming. A one-way ANOVA showed no significant overall effect of priming on logical thinking ability (F = 1.290, p-value = 0.282 > 0.05). However, paired sample t-tests revealed a significant improvement in the negative-valid (t = 3.266, p-value = 0.003 < 0.05) and negative-invalid (t = 2.495, p-value = 0.020) groups, whereas no significant changes were observed in the positive conditions. These exploratory results were based on uncorrected p-values and should be interpreted with caution due to potential Type I error inflation. These results suggest that negative descriptions, even when perceived as valid or invalid, may elicit compensatory motivation to protect one’s self-concept. The findings extend the Situated Inference Model and Self-Enhancement Theory by emphasizing affective valence as a stronger determinant of cognitive engagement than perceived validity. Practically, challenge-based feedback may enhance logical thinking when framed constructively.
