About the Lab

History

The UP Personality and Individual Differences Research Laboratory (UP PIRLab) grew out of a project in a graduate class on Personality Scale Construction taught by Prof. Gregorio G.H. del Pilar during the second semester of academic year 2010 - 2011. The members of the class had decided to construct a personality inventory based on the Five Factor Model of personality traits made up of Filipino trait constructs. The class had decided to name the five-factor inventory of Filipino traits Masaklaw na Panukat ng Loob or Mapa ng Loob. The lab, initially made up of Prof. del Pilar and three graduate students who enrolled in the class, decided to continue working on the inventory until its completion.

This group, later joined by other personality graduate students and one of Prof. Del Pilar’s undergraduate students in a course on Psychological Measurement, met three hours every week for the next four semesters. The team conceptualized additional scales, generated additional items, and performed the necessary field tests and analyses that led to the inventory’s completion in early 2013.

What We Do

The Personality and Individual Differences (PAID) Program is committed to expanding the knowledge base of individual differences and personality processes research. This commitment is pursued through faculty-supervised research conducted as part of graduate coursework, as well as through programs and projects carried out by the UP Personality and Individual Differences Research Laboratory (UP PIRLab). The area has a strong quantitative orientation, but recognizes the importance of qualitative methods in a comprehensive approach to its topics of inquiry.

Current research by area faculty and graduate students cover a wide range that includes personality correlates of creativity, identity and its facets, experience sampling methodology, personality and cognitive correlates of diskarte, and career decisions related to goals and traits. Research on the Masaklaw na Panukat ng Loob (Mapa ng Loob), an inventory that measures the Big Five using Filipino trait constructs developed by the PRL, continues on the instrument's experimental Social Desirability Scale, classical and IRT-approaches to protocol quality indices development, and psychometric properties of the instrument's derived forms (i.e., the English version, and the short forms in Filipino and English).
