Summary

Researchers developed a new scale to measure the continuity and discontinuity of self in stroke survivors. This validated instrument helps assess nursing interventions for improving stroke survivors' sense of self.

Area of Science:

  • Psychology of Stroke Recovery
  • Self-Perception and Identity
  • Instrument Development in Health Sciences

Background:

  • Stroke significantly impacts an individual's sense of self, leading to experiences of both continuity and discontinuity.
  • Existing measures may not adequately capture the nuanced psychological experience of self following stroke.
  • Understanding these shifts is crucial for effective rehabilitation and patient-centered care.

Purpose of the Study:

  • To design and validate a reliable and parsimonious instrument to measure continuity and discontinuity of self post-stroke.
  • To provide a quantitative tool for assessing the subjective experience of self in stroke survivors.
  • To support the evaluation of interventions aimed at enhancing self-continuity.

Main Methods:

Related Experiment Videos

  • Development of a 45-item scale based on existential-phenomenological findings from stroke survivors.
  • Administration of the scale, Barthel Index, and QoL Cantril Ladder to 55 stroke survivors.
  • Principal components factor analysis used for data analysis.

    • Main Results:

    • A 10-item, 2-factor solution was derived, measuring 'discontinuity of self' (Cronbach's alpha = .874) and 'continuity of self' (Cronbach's alpha = .869).
    • Continuity and discontinuity of self were inversely related.
    • Self-continuity correlated with functional abilities, whereas discontinuity did not.

    Conclusions:

    • The developed instrument validates qualitative findings on the paradoxical experience of self post-stroke.
    • This scale offers a reliable method for measuring continuity and discontinuity of self.
    • It can be utilized to assess the efficacy of nursing interventions designed to bolster stroke survivors' sense of continuity.
