The Control Over Nursing Practice Scales demonstrate strong reliability and validity for assessing nurses

Area of Science:

  • Nursing Science
  • Health Services Research
  • Psychometrics

Background:

  • Professional autonomy and control over practice are crucial for registered nurses' job satisfaction and retention.
  • Existing instruments measuring nurses' control over practice require rigorous psychometric evaluation to ensure accuracy and reliability.

Purpose of the Study:

  • To assess the psychometric properties of the Control Over Nursing Practice Scales.
  • To evaluate the reliability and validity of a 33-item instrument measuring six dimensions of nursing practice control.

Main Methods:

  • Psychometric evaluation using data from 1117 registered nurses across four Midwest acute care hospitals.
  • Dimensional analysis, reliability estimation (coefficient alphas), and construct validity assessment (correlations with related constructs).

Related Experiment Videos

  • Factor analysis was used to determine the instrument's dimensional structure.

    • Main Results:

    • Factor analysis confirmed six dimensions, explaining 61% of the variance.
    • Reliability estimates (coefficient alphas) ranged from .75 to .89, indicating good internal consistency.
    • Correlations with autonomy, group cohesion, job stress, and job satisfaction supported construct validity.
    • Critical care nurses reported higher research utilization; baccalaureate-prepared nurses reported higher control via committees.
    • No significant differences were found between part-time and full-time nurses.

    Conclusions:

    • The Control Over Nursing Practice Scales demonstrate acceptable psychometric properties for use in research and practice.
    • The findings support the use of the scales to measure nurses' perceptions of control across various dimensions.
    • Specific nursing roles and educational backgrounds are associated with differing levels of perceived control.
