Background. Multitasking is a rapidly evolving construct and we are in dire need of a sound tool for measuring multitasking behaviors and abilities across socio-cultural contexts. To this end, this study has put forward a cultural adaptation (through back translation) of an already developed (Kushniryk, 2008) measure i.e., Communication Specific Multitasking Measurement Instrument. Objective. This study is intended to translate, adapt, and validate a multitasking measure i.e., Communication Specific Multitasking Measurement Instrument (CSMMI; Kushniryk, 2008) in the context of collectivist culture in Pakistan. Design. The study was composed of two parts. The first part was completed in two phases. Phase I employed back and forward translation methods to translate the multitasking measure into an indigenous language. Phase II provided empirical validity of the translated and adapted instrument (CSMMI) using exploratory factor analysis (EFA) on data collected from a sample of 230 married individuals. The second part of the study was designed to establish construct validity of the translated instrument using confirmatory factor analysis (CFA) on a larger data set of married individuals. Results. EFA using a varimax rotation on all 19 items of CSMMI showed that the instrument is a three-dimensional measure. CFA confirmed that the translated and adapted instrument is also a three-dimensional measure on the larger data set. Analysis of the intraclass correlation and alpha coefficient provided sound evidence for validity and reliability of the measure (CSMMI). Conclusion. The findings of this study indicate that the translated and adapted multitasking measure (CSMMI) is reliable and valid when applied to the culturally collectivist population of Pakistan. This also pertains to any other populations where the translation is adequately applicable.

ABSTRAK Tujuan dari penelitian ini adalah mendeskripsikan kelayakan teoritis dan empiris dari instrumen tes literasi sains fisika yang dikembangkan dan mendeskripsikan profil kemampuan literasi sains siswa. Penelitian ini menggunakan model Research and Development (R&D) yang langkah-langkahnya mengacu pada Sugiyono (2013). Teknik pengumpulan data pada penelitian ini yaitu dengan metode validasi yang dilakukan oleh dua dosen dari jurusan Fisika Universitas Negeri Surabaya dan metode tes yang dilakukan terhadap 50 siswa. Data yang telah terkumpul dianalisis dengan metode analisis deskriptif kuantitatif. Persentase validitas teoritis rata-rata pada ranah materi, konstruksi, dan bahasa sebesar 89,82% atau berada pada kategori sangat layak. Hasil ujicoba produk pada 50 siswa dianalisis tingkat kesukaran, daya pembeda, reliabilitas, dan validitas itemnya. Dari analisis tersebut diperoleh validitas empiris sebanyak 56,25% dari keseluruhan soal dinyatakan layak secara empiris. Instrumen tes yang telah layak kemudian digunakan untuk mendeskripsikan profil kemampuan literasi sains siswa. 2% siswa dengan kategori sangat tinggi, 8% dengan kategori tinggi, 32% dengan kategori sedang, 8% dengan kategori rendah, dan 50% dengan kategori sangat rendah. Kemampuan literasi sains pada kompetensi menafsirkan data dan bukti secara ilmiah memiliki skor rata-rata tertinggi, sedangkan mengevaluasi dan merancang penyelidikan ilmiah memiliki skor rata-rata terendah. Kata kunci: instrumen tes; validitas teoritis; validitas empiris; profil literasi sains. ABSTRACT The purpose of this study was to describe the theoritical and empirical feasibility of physical scientific literacy test instrument which was developed and to describe the profile of student scientific literacy abilitie. This study using Research and Development (R&D) model whose steps refer to Sugiyono (2013). Data collection techniques in this study are the validation method that done by two lecturers from the phyic department of State University of Surabaya and test method that done by 50 students. The data that has been collected were analyzed using quantitative decriptive analysis method. The percentage of average theoritical validity in the realms of material, construction, and language is 89,82% or in the very feasible category. The result of product trials on 50 students analiyzed the level of difficulty, distinguishing power, reliability, and item validity. From this analysis, it is stated that 56,25% of the total questions are empirically feasible. The appropriate test instrument is then used to describe the profile of students scientific literacy abilities. 2% of students are in very high category, 8% are in high category, 32% are in medium category, 8% ar in low category, and 50% are in very low category. The cientif literacy ability in the competence to interpret data and evidence scientifically has the highest average score, while evaluating and designing scientific investigations has the lowest average score. Keywords: test instrument; theoritical validity; empirical validity; scientific literacy profile.

This study aims to produce a package of questions measuring internalized argumentation skills (IAS) that meet the requirements of logical validity (content and construct) and empirical validity. The research follows Fenrich’s development model. The implementation of the test package to test the empirical validity involved 30 participants, students of the Chemistry Education Study Program. The research data were analyzed descriptively. The results of the research, a package of IAS measuring questions for chemistry students has been successfully developed. The IAS measuring test package consists of five questions with details of one easy level question, three medium level questions, and one difficult level question. The package of questions developed has met the requirements of logical validity (content and construct) and empirical validity.
