Abstract

This article introduces the Klasika software developed to run item and test analysis using the Classical Test Theory approach. Classical Test Theory is one of the specialized competencies and skills that undergraduate students of psychology must possess. Classical Test Theory becomes a mandatory course for all schools or departments of psychology in Indonesia. This article also provides a theoretical foundation of Classical Test Theory's essential concepts and statistical methods, specifically related to items and test statistics. The item analysis and test reliability procedures using Klasika, starting from the data preparation untill data interpretation, are explained with an empirical illustration. Finally, the analysis results using Klasika are compared with the results from Quest software to test the accuracy of the estimation results.

Abstract

Work engagement is a positive psychology construct widely sought after and developed in various countries. Psychometric validation requires statistical analysis to measure and differentiate individuals across different cultures. This study aims to validate the Utrecht Work Engagement Scale-17 (UWES-17) instrument on hospitality workers in state-owned companies in Indonesia. The study population comprised 3185 individuals, representing various positions and types of hospitality service jobs within the land transportation sector of a state-owned enterprise. A non-probability sampling approach, specifically convenience sampling, was employed, selecting participants based on their accessibility and willingness to participate. The participants, aged between 18 and 62, came from diverse fields and work areas. Analysis of item responses in the test was the Rasch Model with a study focus on item fit and person fit from the UWES-17 Scale. In addition, assumption tests of unidimensionality and local independence were performed to ensure the validity of the measurement model. The scale’s reliability was also assessed to evaluate the instrument’s consistency. The results showed that the items were overall fit, but the criteria for person fit were unmet. This is due to the tendency for uniformity and too many diverse positions and cultural tendencies of state-owned companies. The implication is that further item development and confirmation are needed on the constituent aspects, especially the absorption constituent items. Additionally, developing a more consistent shorter version or discovering other dimensions of work engagement that are specific to collectivist societies may be possible.

Abstract

AbstractCurriculum reform plays an essential role in assuring the success of systematic educational change. The purpose of this study is to portray the government policy and the issues of the Curriculum 2013 implementation. This study employed qualitative methodology using document analysis, observation and Focused Group Discussion (FGD)   as data collection techniques. The results of this study show that the curricula philosophy of curriculum reform was well-articulated and relevant to meet the requirements of twenty-first century learning competencies. However, the curricula implementation process faced substantial challenges with technical problems regarding the national standards of education document, teacher training and competences, the availability of school textbooks, and classroom assessment implementation. The findings of this study have several implications for implementing the national curriculum in Indonesia. Therefore, alignment between the national standards of education document, the curriculum structure, and the assessment system is required in order to ensure the successful implementation of Curriculum 2013 throughout the nation.AbstrakReformasi kurikulum memainkan peran penting dalam memastikan keberhasilan perubahan pendidikan yang sistematis. Tujuan dari penelitian ini adalah untuk menggambarkan kebijakan pemerintah dan isu-isu implementasi Kurikulum 2013. Penelitian ini menggunakan metodologi kualitatif menggunakan analisis dokumen, observasi dan diskusi kelompok terpumpun sebagai teknik pengumpulan data. Hasil penelitian ini menunjukkan bahwa filosofi reformasi kurikulum diartikulasikan dengan baik dan relevan untuk memenuhi persyaratan kompetensi pembelajaran abad kedua puluh satu. Namun, proses implementasi kurikulum menghadapi tantangan besar dengan masalah teknis mengenai dokumen yang terkait dengan standar nasional pendidikan, pelatihan dan kompetensi guru, ketersediaan buku pelajaran di sekolah, dan implementasi penilaian di dalam kelas. Temuan penelitian ini memiliki beberapa implikasi untuk menerapkan kurikulum nasional di Indonesia. Oleh karena itu, diperlukan keselarasan antara dokumen standar nasional pendidikan, struktur kurikulum, dan sistem penilaian untuk memastikan keberhasilan implementasi Kurikulum 2013 di seluruh negara.

Abstract

Studi ini menggunakan simulasi Monte Carlo dilakukan untuk melihat pengaruh ukuran sampel dan intraclass correlation coefficients (ICC) terhadap bias estimasi parameter multilevel latent variable modeling. Kondisi simulasi diciptakan dengan beberapa faktor yang ditetapkan yaitu lima kondisi ICC (0.05, 0.10, 0.15, 0.20, 0.25), jumlah kelompok (30, 50, 100 dan 150), jumlah observasi dalam kelompok (10, 20 dan 50) dan diestimasi menggunakan lima metode estimasi: ML, MLF, MLR, WLSMV dan BAYES. Jumlah kondisi keseluruhan sebanyak 300 kondisi dimana tiap kondisi direplikasi sebanyak 1000 kali dan dianalisis menggunakan software Mplus 7.4. Kriteria bias yang masih dapat diterima adalah < 10%. Hasil penelitian ini menunjukkan bahwa bias yang terjadi dipengaruhi oleh ukuran sampel dan ICC, penelitian ini juga menujukkan bahwa metode estimasi WLSMV dan BAYES berfungsi lebih baik pada berbagai kondisi dibandingkan dengan metode estimasi berbasis ML.Kata kunci: multilevel latent variable modeling, intraclass correlation coefficients, Metode Markov Chain Monte Carlo THE IMPACT OF SAMPLE SIZE AND INTRACLASS CORRELATION COEFFICIENTS (ICC) ON THE BIAS OF PARAMETER ESTIMATION IN MULTILEVEL LATENT VARIABLE MODELING: A MONTE CARLO STUDYAbstractA monte carlo study was conducted to investigate the effect of sample size and intraclass correlation coefficients (ICC) on the bias of parameter estimates in multilevel latent variable modeling. The design factors included (ICC: 0.05, 0.10, 0.15, 0.20, 0.25), number of groups in between level model (NG: 30, 50, 100 and 150), cluster size (CS: 10, 20 and 50) to be estimated with five different estimator: ML, MLF, MLR, WLSMV and BAYES. Factors were interegated into 300 conditions (4 NG  3 CS  5 ICC  5 Estimator). For each condition, replications with convergence problems were exclude until at least 1.000 replications were generated and analyzed using Mplus 7.4, we also consider absolute percent bias <10% to represent an acceptable level of bias. We find that the degree of bias depends on sample size and ICC. We also show that WLSMV and BAYES estimator performed better than ML-based estimator across varying sample sizes and ICC's conditions.Keywords: multilevel latent variable modeling, intraclass correlation coefficients, Markov Chain Monte Carlo method

Abstract

Background: Sleep quality is a critical determinant of recovery outcomes among patients admitted to intensive care units (ICUs); however, accurate sleep assessment remains challenging due to environmental disturbances and intensive medical interventions. The Richards–Campbell Sleep Questionnaire (RCSQ) is widely used to assess subjective sleep quality, yet evidence regarding its psychometric performance in Indonesian ICU settings remains limited. Objective: The purpose of this study was to evaluate the validity and reliability of RCSQ in the ICU and assess the extent to which this instrument can accurately reflect the patient's sleep experience in the ICU. Methods: A methodological cross-sectional study was conducted involving 11 adult ICU patients recruited using a total sampling technique. Data were collected between April and May 2025 using the Indonesian version of the RCSQ. Construct validity was assessed using item–total correlation analysis, while internal consistency was evaluated using Cronbach’s alpha coefficient. Descriptive statistics were used to summarize participants’ demographic characteristics. Results: All RCSQ items demonstrated satisfactory construct validity, with item–total correlation coefficients exceeding the critical r-value (r > 0.521) and statistical significance at p < 0.05. The instrument showed good internal consistency, with a Cronbach’s alpha value of 0.810, indicating reliable measurement of subjective sleep quality among ICU patients. Conclusion: The Indonesian version of the Richards–Campbell Sleep Questionnaire demonstrates acceptable validity and reliability for assessing subjective sleep quality in ICU patients. Nevertheless, further studies with larger and more diverse samples are recommended to confirm its robustness and to explore integration with objective sleep assessment methods in intensive care settings.

Abstract

Background: Sleep quality is an important yet understudied element influencing postoperative recovery in intensive care units. Considering that there is a lack of consistent knowledge of the quality of sleep, it is difficult to establish appropriate tests and therapies. Objective: To do a conceptual analysis of sleep quality in postoperative intensive care units patients utilizing the Walker and Avant framework, delineating its qualities, antecedents, consequences, and empirical referents. Methods: This study used the Walker and Avant eight-step process for idea analysis, which included a systematic literature evaluation of papers published between 2020 and 2024 in databases such as PubMed, Scopus, ScienceDirect, and ProQuest. Data was evaluated to determine important defining qualities, causes, outcomes, and measurable indicators of sleep quality. Results: The analysis identified four defining attributes of sleep quality: sleep architecture, sleep disturbances, subjective experience, and physiological indicators. Antecedents included environmental noise, lighting, pain, anxiety, and frequent medical interventions. Poor sleep quality was associated with adverse outcomes such as increased delirium risk, delayed wound healing, and prolonged intensive care units      stays. Empirical referents included patient-reported tools like the Pittsburgh Sleep Quality Index, polysomnography, and actigraphy. Conclusion: Sleep quality is a multidimensional concept central to postoperative care in intensive care unit. Addressing environmental and psychological factors through targeted interventions can improve sleep quality and enhance recovery outcomes.
