Summary

The Skin Picking Scale (SPS) is a new, reliable, and valid six-item tool to assess skin picking severity in patients. It helps differentiate between severe self-injurious and non-self-injurious skin pickers.

Area of Science:

  • Psychiatry
  • Psychometrics
  • Behavioral Science

Background:

  • Skin picking disorder is a significant concern.
  • Existing assessment tools may not fully capture the severity of skin picking behaviors.
  • A reliable and valid measure is needed for clinical and research settings.

Purpose of the Study:

  • To develop and validate the Skin Picking Scale (SPS), a brief self-report measure.
  • To assess the reliability and validity of the SPS in a clinical population.
  • To establish a cutoff score for differentiating severity levels of skin picking.

Main Methods:

  • Development of an initial eight-item scale based on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
  • Administration of the scale to 28 severe self-injurious and 77 non-self-injurious skin pickers.

Related Experiment Videos

  • Psychometric analyses including internal consistency (Cronbach's alpha), construct validity (correlations with duration, BDI, BAI, emotional intensity), and receiver operating characteristic (ROC) analysis for cutoff determination.

    • Main Results:

    • A six-item Skin Picking Scale (SPS) with a score range of 0-24 was finalized.
    • The SPS demonstrated moderate internal consistency (Cronbach's alpha = .80).
    • SPS scores significantly correlated with picking episode duration, depression (BDI), anxiety (BAI), and emotional intensity during picking.
    • A cutoff score of 7 on the SPS effectively differentiated severe self-injurious from non-self-injurious skin pickers.

    Conclusions:

    • The Skin Picking Scale (SPS) is a valid and reliable self-report measure.
    • The SPS is suitable for assessing skin picking severity in medical and psychiatric patients.
    • The scale provides a useful tool for both clinical assessment and research purposes.
