Drug Abuse and Addiction: Pharmacological Phenomena

433
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Area of Science:

  • Psychiatry
  • Psychology
  • Digital Health

Background:

  • The rapid increase in TikTok usage necessitates specific tools to assess potential addiction.
  • Existing social media addiction measures may not fully capture the nuances of TikTok use.
  • There is a critical need for a valid psychometric instrument to measure TikTok addiction.

Purpose of the Study:

  • To develop and validate a reliable and specific tool for measuring TikTok addiction.
  • To create the TikTok Addiction Scale (TTAS) with strong psychometric properties.

Main Methods:

  • Literature review to generate items, followed by expert content validity assessment.
  • Cognitive interviews for face validity and factor analysis (exploratory and confirmatory) for construct validity.
  • Concurrent validity assessed using established scales (BSMAS, PHQ-4, BFI-10); reliability examined via Cronbach's alpha, McDonald's Omega, and other measures.

Main Results:

  • The TikTok Addiction Scale (TTAS) is a 15-item, six-factor scale (salience, mood modification, tolerance, withdrawal, conflict, relapse) explaining 80.70% of variance.
  • Excellent concurrent validity was confirmed through significant correlations with BSMAS, PHQ-4, and BFI-10.
  • High internal consistency was demonstrated with Cronbach's alpha (0.911) and McDonald's Omega (0.914).

Conclusions:

  • The TTAS is a valid, reliable, and user-friendly instrument for assessing TikTok addiction.
  • Further validation across diverse languages and populations is recommended to enhance the scale's generalizability.
  • The TTAS provides a valuable tool for researchers and clinicians studying social media addiction.
