Description:	Pentaksiran personaliti merujuk kepada proses membuat pengukuran dan penilaian terhadap darjah perbezaan dinamik antara individu berdasarkan trait psikologi, attitud, perlakuan dan proses kognitif. Personaliti dipengaruhi oleh faktor budaya, bahasa dan sampel. Model Personaliti Lima Faktor telah mengemukakan lima domain personaliti iaitu keterbukaan, kehemahan, ekstraversi, kesetujuan dan neurotism. Kajian ini dijalankan berdasarkan dua objektif utama. Objektif pertama adalah untuk menentukan bilangan domain personaliti dalam kalangan pelajar kolej matrikulasi manakala objektif kedua adalah menentukan kesahan konstruk dan kebolehpercayaan konstruk bagi instrumen International Personality Item Pool (IPIP). Kajian dijalankan terhadap 946 orang pelajar matrikulasi (548 peringkat pertama dan 398 peringkat kedua). Analisis faktor penerokaan melalui putaran varimax mendapati enam faktor mempunyai nilai eigen melebihi 1. Keenam-enam faktor ini menyumbang sebanyak 62.97% terhadap keseluruhan varian diterangkan. Sebanyak 26 item telah digugurkan di peringkat ini. Keenam-enam konstruk yang diperolehi dinamakan sebagai keterbukaan, kehemahan, ekstraversi, kesetujuan, neurotism dan keyakinan sosial. Analisis faktor konfirmatori (CFA) dijalankan bagi menentukan kesahan konstruk (kesahan konvegen dan kesahan diskriminan) dan kebolehpercayaan konstruk (Cronbach alpha dan kebolehpercayaan komposit). Pengujian dijalankan menggunakan perisian statistik SPSS 20, AMOS 18 dan Winstep 3.72. Kesahan konvegen diuji melalui nilai korelasi item terhadap skor keseluruhan berada antara 0.40-0.89 dan nilai muatan faktor item-item terhadap konstruk bagi model pengukuran yang dibina adalah ≥0.50. Nilai purata varian ekstrak AVE setiap konstruk memenuhi kriteria ditetapkan iaitu ≥0.50. Kriteria Goodness of fit bagi model pengukuran dibina mempunyai nilai Comperative Fit Index (CFI), Tucker Lewis Index (TLI), Goodness fit Index (GFI) adalah ≥0.90, RootMean Square Error Approximation (RMSEA antara 0.03-0.08) dan nilai CMIN/df ≤5. Kesahan diskriminan diuji melalui kriteria Fornell-Larcker dan muatan faktor merentas konstrak (cross-loading). Kebolehpercayaan instrumen ditentukan melalui penentuan kebolehpercayaan komposit (CR) dan Cronbach alpha bagi setiap domain berada antara 0.70-0.88. Pengujian melalui Model Pengukuran Rasch turut mengesahkan ciri psikometrik instrumen personaliti IPIP (24 item) melalui penentuan nilai kebolehpercayaan item (0.99), kebolehpercayaan individu (0.72), indek pengasingan item (8.59), indek pengasingan individu (2.47), polariti item (PTMEA CORR >0) dan peta item individu.,Personality assessment refer to a process of measuring and evaluating the degree of dynamic different between individual based on psychological trait, attitude, behaviour and cognitive process. Personality domain depend on cultural, language and sample. Big Five personality factor proposed five personality domain which are openness, consciousness, extraversion, agreeableness and neuroticism. This study was conducted based on two main objectives. The first objective is to identify the number of personality domain among matriculation students while the second objective is to assess the construct validity and construct reliability for International Personality Item Pool instrument. This study involved 946 sample (548 sample in first phase and 398 sample in second phase). Exploratory factor analysis via varimax rotation had identified six components with eigenvalue more than 1. All six components explained 62.97% of total variance explain. Result shown that 26 item must be deleted. All six components labelled as openness, consciousness, extraversion, agreeable, neuroticism and social confident. Confirmatory factor analysis (CFA) was conducted to assess construct validity (convergent validity and discriminant validity) and construct reliability (Cronbach alpha and composite reliability). The assessment had done through SPSS 20, AMOS 18 and Winsteps 3.72. Convergent validity were assess base on correlation analysis, all the item had correlation coefficient 0.4-0.89, factor loading for measurement model ≥0.5, Average Varians Explain (AVE) ≥0.5 and goodness of fit index Comparative fit index (CFI), Tucker-Lewis Index (TLI), Goodness of fit index (GFI) ≥0.90, Root Mean Square Error of Approximation (RMSEA) between 0.03-0.08 and CMIN/df ≤5.0. Discriminant analysis had assess through cross-loading and Fornell-Larcker criteria. Construct reliability were assess through determination of Composite reliability (CR) and Cronbach alpha for each domain is between 0.70- 0.88. Further analysis with Rasch Model (Winstep 3.72) approved that 24 items of International personality Item Pool instrument has a good psychometric sound in term of item reliability (0.99), person reliability (0.72), item separation (8.59), person separation (2.47), item polarity (PTMEA CORR >0) and item-person map.,Master
