Mapa ng Loob

Completed in May 2013, after six item testing studies over five successive semesters

Initially meant to be a revision of the

"...most of the dimensions measured by Philippine personality inventories overlap considerably with, and are adequately encompassed by, dimensions of the five-factor model..." p. 97

Conclusion: Katigbak, Church, Lapena, Carlota & del Pilar (2002)

Construction of the scales of the Mapa ng Loob

Construct definition Item-writing Item review (to improve phrasing, to

eliminate highly similar items, and assignment of prototypicality ratings)

Item testing Reliability analysis Factor analysis

Factor Analysis

Since the Mapa aims to measure the five factors, it has to demonstrate that the five facets group as expected.

International Personality Item Pool (IPIP, L. Goldberg, 2008)

collection of personality items in the public domain, available on the Internet, established by Lewis Goldberg in the 1990's

aims to promote personality and individual differences research by making available, for free, measures that are highly correlated with well-known but copyrighted measures such as the NEO PI-R, the MMPI, the 16 PF, the CPI, etc.

Borlasa, Magayanes, Menorca & Syjueco, 2014

Participants: 120 UP Diliman college students

Correlated the English Mapa domain scale scores with the International Personality Item Pool Big Five scales (20 items per domain scale)

Del Pilar, 2014: Ratings from current best friends and childhood best friends

Participants: two undergraduate classes in Psychological Measurement in UP Diliman, who recruited current and chilhood best friends

Current best friend pairs N=98, childhood best friend pairs N= 80

STUDENTS (N = 49) BEST FRIENDS (N=49) Rating Mapa score Mapa Score

Participants with current best friends

70 females and 28 males 98 % were aged 17-22 (max age was 26) Mean Age = 19.4, SD = 1.34 56 Psychology Majors; 42 non-

Psychology Majors

Participants with childhood best friends

61 females and 19 males Mean Age = 19.3, SD = .92 (17-21) 39 Psychology Majors; 41 non-

Psychology Majors

First five items on the rating instrument Del Pilar, 2014

The score on a rating scale for a facet was the rating on the facet, eg, Hina ng Loob.

Domain rating score = rating on facet 1 + rating on facet 2 + rating on facet 3 + rating on facet 4

Example: Rating score on Neuroticism = rating on Hina ng Loob + rating on Pagkamaramdamin + rating on Pagkamapag-alala + rating on Pagkasumpungin
