| Summary: | One of the most crucial factors that influence the success of a construction project is
communication. However, past studies found that communication failure frequently
occurs at civil engineering workplaces. Among communication failures reported were oral
communications, such as giving instruction and briefing; skills, which are supposed to be
mastered by engineering graduates during their study years. Thus, students need to equip
themselves with proper oral communication skills before they enter the industry. As such,
this study aimed to develop a valid and reliable survey instrument to measure Workplace
Oral Communication Skills (WOCS) by performing a step-by-step instrument validation
through exploratory factor analysis (EFA). The questionnaire consisted of nine components,
with 39 items of Workplace Oral Communication Skills (WOCS). In the study, the EFA
was carried out in three rotations until every item’s factor loading met the minimum
requirement of 0.60. Notably, Bartlett’s test of Sphericity was significant (p <0.05), and the
Kaiser-Meyer-Olkin test was more than 0.60 in every rotation, which means that the sample
size was adequate. Furthermore, all components showed a Cronbach Alpha >0.70, which
indicates that the instrument is reliable. The final result of the EFA showed that the WOCS
construct only had six components with 25
items. Therefore, this study had managed to
validate the instrument. Thus, Confirmatory
Factor Analysis (CFA) can proceed in the
next study using the validated instrument.
