Abstract
Background:One of the preventive strategies for chronic low back pain among operating room nurses is instructing proper body mechanics and postural behavior, for which the use of the Transtheoretical Model (TTM) has been recommended.Methods:Eighty two nurses who were in the contemplation and preparation stages for adopting correct body posture were randomly selected (control group = 40, intervention group = 42). TTM variables and body posture were measured at baseline and again after 1 and 6 months after the intervention. A four-week ergonomics educational intervention based on TTM variables was designed and conducted for the nurses in the intervention group.Results:Following the intervention, a higher proportion of nurses in the intervention group moved into the action stage (p < 0.05). Mean scores of self-efficacy, pros, experimental processes and correct body posture were also significantly higher in the intervention group (p < 0.05). No significant differences were found in the cons and behavioral processes, except for self-liberation, between the two groups (p > 0.05) after the intervention.Conclusions:The TTM provides a suitable framework for developing stage-based ergonomics interventions for postural behavior.

Summary
Work-related musculoskeletal disorders (WMSD), especially lower back pain are common among operating room nurses (Sheikhzadeh, Gore, Zuckerman, & Nordin, 2009). One of the preventive strategies for chronic low back pain is instructing proper body mechanics and posture (Owen, Keene & Olson, 2002). The Transtheoretical Model (TTM), one of the stage models, postulates that people differ in their readiness to adopt a new behavior. According to the TTM, individuals adopting a new behavior go through six stages of change: (a) pre-contemplation - no intention of changing behavior within the 6 months; (b) contemplation-intends to make a change behavior within the 6 months; (c) preparation - intends to make a www.ccsenet.org/gjhs.
