Purpose: Understanding the factors that affect nursing staffs’ intention and practice of physical restraint (PR) on older adults help develop restraint-reduction programs. This study aimed to identify the relationship between the Theory of Planned Behavior (TPB) constructs and nursing staffs’ practice to use PR in long-term care (LTC) facilities.
Patients and Methods: A cross-sectional survey was conducted via convenience sampling among 316 nursing staff in six Chinese LTC facilities. PR-TPB questionnaire and the practice subscale of the Chinese version of the Staff Knowledge, Attitudes and Practices Questionnaire regarding PR were used to collect the data. Structural equation modeling (SEM) was used to examine the relationship between variables.
Results: The SEM fit well with the data (χ²/df  =1.639, RMSEA = 0.045, CFI= 0.955, GFI=0.945). Attitude (β =0.536, P < 0.001) and perceived behavioral control (PBC) (β =0.139, P < 0.05) predicted intention (R² =0.359). PBC was a significant predictor of practice, with R²  accounting for 0.151.
Conclusion: TPB provided useful insight into better understanding nursing staffs’ PR practices, although it did not support all the TPB principles significantly. Prospective studies may be conducted to design and implement multi-component interventions based on TPB and explore the effectiveness of PR reduction in LTC facilities in-depth.
