Factors Influencing Waste Segregation Behavior Among Personnel at Nakhon Phanom Rajanagarindra Psychiatric Hospital

Abstract

Purpose :

To examine factors influencing waste segregation behavior among hospital personnel at Nakhon Phanom Rajanagarindra Psychiatric Hospital using the PRECEDE-PROCEED Model framework, which encompasses predisposing, enabling, and reinforcing factors.

Study design:

Cross-sectional quantitative research design.

Materials and Methods:

A sample of 124 hospital personnel was selected through proportional stratified random sampling. The research instrument was a questionnaire validated by three experts for content validity, demonstrating high reliability with Cronbach's alpha of 0.93. Data were analyzed using descriptive and inferential statistics, including percentages, means, standard deviations, t-tests, one-way ANOVA, Pearson's correlation, and stepwise multiple regression analysis.

Main findings:

The majority of participants were female (65.85%), with a mean age of 40.17 years (SD = 9.38), average work experience of 10.19 years (SD = 8.24), and 73.39% had received waste management training. Personnel demonstrated moderate knowledge of waste management (M = 2.54, SD = 0.70), favorable attitudes toward waste management (M = 3.29, SD = 0.36), and good waste segregation behavior (M = 3.53, SD = 0.22). Hypothesis testing indicated that all demographic factors showed no significant relationship with waste segregation behavior (p > 0.05). Conversely, knowledge, attitudes, self-efficacy, access to information, resources and facilities, organizational support, and peer support demonstrated significant positive correlations with waste segregation behavior (p < 0.01). Stepwise multiple regression analysis revealed that only two factors significantly predicted waste segregation behavior: self-efficacy (β = 0.448, p < 0.001) and organizational support (β = 0.226, p < 0.01), explaining 38.8% of the variance.

Conclusion and recommendations:

Enhancing personnel's confidence in their waste management capabilities, coupled with establishing effective organizational support systems, can significantly improve waste segregation behavior. Administrators should prioritize personnel capacity development through hands-on training programs, ensure adequate resources and equipment, and foster a work environment that supports pro-environmental behavior.
