Scientific Title

PhilSHIFT Project 1 - Chronotype of Filipino non-shift workers and shift workers
 

Project Description

Project 1 of the University of the Philippines’ PhilSHIFT Research Group aims to further PhilSHIFT’s database of chronotypes of non-shift working Filipinos and develop a tool for chronotype evaluation of Filipino shift workers. They are intended as references and tools for future chronotype and shift work research in the Philippines.

This study is the first project under the research program “Chronotype-Specific Adjustment to Shift Work of Contact Center Agents in the Philippines”. A later study will look at the chronotype, health, and experience of newly-hired contact center agents as they pursue permanent night work.
 
PhilSHIFT is a collaborative research program of the University of the Philippines Center for Integrative and Development Studies (CIDS). Its research projects concern the Filipino chronotype (body clock) and shift work.

Health Condition(s) or Problem(s) Studied

The objective of the entire PhilSHIFT research program is to study the chronotype in the Filipino population as it may be influenced by certain characteristics and shift work in contact centers.
 
Project 1 (Philippine Chronotype and Social Jetlag Survey) concerns the chronotype of non-shift working and shift working Filipinos. It aims to:
1. determine the distribution of chronotypes among Filipino non-shift workers using the Philippine Munich Chronotype Questionnaire (PhilMCTQ) in key areas of the Philippines with the most contact center workers

2. extrapolate the chronotype distribution of Filipino shift workers in contact centers using the chronotype distribution of non-shift workers in the same areas

3. determine how the distribution of chronotypes may be influenced by age, sex, and subjective report of outdoor light exposure

4. develop the Philippine Munich Chronotype Questionnaire version for shift workers (PhilMCTQ-Shift) for use in research concerning shift workers in Philippine establishments, particularly contact centers

5. The Filipino chronotype (body clock type), its distribution in the Philippine population, influence of certain characteristics (age, sex, and outdoor light exposure) on chronotype distribution, and relationship with health factors (sleep, BMI, stimulant consumption, etc.)

Primary Outcomes

This project aims to elicit knowledge on the distribution of chronotypes of Filipinos and how this is influenced by age, sex and amount of time spent outdoors. The database will thereby serve as a reference point for all future studies in the Philippines. The study will also develop the Philippine Munich Chronotype Questionnaire for Shift Workers (PhilMCTQ-Shift), which is intended for a succeeding project on the chronotype and shift workers in contact centers.

Taking into account past project activities and outcomes, the following are the feasible outputs of Project 1 this 2016:
1. chronotype distribution among non-shift workers surveyed in the target metro cities of Metro Manila, Metro Cebu, Metro Clark and Metro Davao (where sufficient respondents numbers would allow)

2. data on age, sex, and outdoor light exposure (factors that may influence the chronotype distribution)

3. a chronotype questionnaire for shift workers in the contact center industry, PhilMCTQ-Shift, which would be subjected to validation in a future study

4. paper-based Filipino versions of the PhilMCTQ and PhilMCTQ-Shift

5. a documentation of promotional efforts for the PhilMCTQ survey, which may be reported for the benefit of researchers interested in epidemiologic studies of the human chronotype
