    Area of Science:

    • Health psychology
    • Patient-provider communication
    • Psychometric instrument development

    Background:

    • Effective patient self-disclosure is crucial for quality healthcare.
    • Existing measures may not capture key areas of patient difficulty in disclosure.
    • Developing a validated instrument is essential for research and clinical practice.

    Purpose of the Study:

    • To develop and validate a patient self-disclosure questionnaire.
    • To assess patient difficulties in disclosing personal problems, health responses, and lifestyle information.
    • To examine the psychometric properties and construct validity of the new instrument.

    Main Methods:

    • Four studies were conducted involving questionnaire development and testing.
    • A 21-item, 7-point rating scale questionnaire was created based on patient and clinician input.

  • Factor analysis (principal components analysis with varimax rotation) and reliability analyses (Cronbach's alpha, test-retest) were performed.
  • Construct validity was assessed through correlations with locus of control, clinician empathy, and heart rate changes.
  • Main Results:

    • The questionnaire demonstrated good internal consistency (Cronbach's alpha .82-.83) and test-retest reliability (r = .81-.87).
    • Factor analysis revealed three underlying factors accounting for 59% of the variance.
    • Patient self-disclosure was significantly influenced by locus of control and perceived clinician empathy.
    • Self-disclosure covaried with physiological measures (heart rate changes).

    Conclusions:

    • The developed patient self-disclosure questionnaire is a reliable and valid measure.
    • The instrument effectively assesses patient difficulties across key disclosure domains.
    • Findings highlight the psychological and interpersonal factors influencing patient self-disclosure in healthcare settings.
