| description | Studies have shown that a workplace safety culture (WSC) is lacking among the general
workforce in Nigeria. Poor WSC can result in adverse impacts on workers' health and
high remedial costs for employers. To improve WSC, workers need to improve on
knowledge, attitude, and practices related to office ergonomics towards WSC through
effective health interventional programs at the workplace.
The study aimed to develop, implement and evaluate the effectiveness of the Work
Safety Culture Health Education Module (WSCHEM) among government
administrative workers in Abeokuta, Southwestern Nigeria.
The study was a two-armed, single-blinded cluster randomized controlled trial involving
247 public sector administrative workers from clusters of 20 ministries in Abeokuta,
Southwestern Nigeria. The intervention group was given WSCHEM, whereas the
waitlist group received a seminar on team building and leadership skills and received the
WSCHEM after the intervention program ended. The researcher administered the
module to the intervention group. For the waitlist group, one of the research assistants
from the ministry of finance delivered the seminar on team building and leadership skills
for morning and afternoon sessions. The evaluation was done three times using the first
formal validated, self-administered Work Safety Culture Questionnaire (WSCQ) among
the administrative workers: first at baseline, second at one month, and third at three
months post-intervention. The validation of the Work Safety Culture Questionnaire
(WSCQ) confirmed high reliability and validity for the evaluation of the level of
knowledge, attitude, and practices toward work safety culture (WSC) among the study
population. The respondents’ knowledge, attitude, and practices toward workplace
safety culture (WSC) was measured using the Work Safety Culture Questionnaire
(WSCQ). Data obtained was analyzed by using the IBM SPSS Statistics 25. Chi-Square
Test was used for bivariate analysis, and Generalized Estimating Equations (GEE) for
the multivariate analysis.
The results showed no statistically significant differences between groups regarding the
respondents’ characteristics (socio-demographic and occupational/office related
ergonomic factors) and the outcome variables (knowledge attitudes and practices) on
WSC at baseline. For practices towards WSC, both intervention (β 6.8, 95%CI 4.85,
8.72) and time (β 6.2, 95%CI 4.49, 7.94) had a statistically significant effect on the
respondents’ practices towards WSC in the per-protocol analysis. In the secondary
outcomes, both knowledge of WSC, intervention (β 3.5, 95%CI 2.8, 4.2) and time (β 3.4,
95%CI 2.7, 5.9) and attitudes towards WSC, intervention (β1.7, 95%CI 1.25, 2.23) and
time (β 2.3, 95%CI 1.92, 2.76) had a significant effect on the respondents’ level of
knowledge and attitudes respectively towards WSC.
The WSCHEM effectively improved respondents’ knowledge, attitude, and practices
related to office ergonomics (which are exercising, using computer screen cover, not
sitting in one position for a long time, and attending office ergonomic course) toward
work safety culture. Employers are encouraged to adopt WSCHEM as an adjunct to their
workplace’s pre-existing control measures to improve their workers' knowledge,
attitude, and practices toward work safety culture. |
