The Penn State Electronic Cigarette Dependence Index (PSECDI) is a validated assessment tool developed by researchers at Penn State University. It measures an individual’s level of dependence on electronic cigarettes (e-cigarettes) through a structured questionnaire, helping clinicians and researchers evaluate addiction patterns.
Structure of the PSECDI
The index consists of 11 key items that probe various aspects of e-cigarette use. Each item assesses behaviors and symptoms related to dependence.
- Frequency of e-cigarette use throughout the day.
- Urges to use e-cigarettes when not allowed.
- Morning use patterns and craving intensity.
- Experiences with withdrawal symptoms.
- Difficulty in controlling use despite efforts.
Respondents rate each item on a Likert scale, typically from 1 (low dependence) to 4 (high dependence), providing quantifiable insights.
Scoring and Interpretation
Scores are summed across all items for a total, ranging from 11 to 44. Higher scores indicate greater dependence severity.
- Scores of 11–20 suggest low dependence.
- 21–30 indicate moderate dependence.
- 31–44 reflect high dependence.
This scoring system helps identify at-risk individuals for intervention, such as cessation programs or clinical studies.
Purpose and Applications
The PSECDI aids in public health initiatives by tracking e-cigarette addiction trends. It is used in clinical settings to tailor treatments and in research to study health impacts.
Key benefit: Its reliability allows for consistent measurement across populations, supporting evidence-based approaches to reduce e-cigarette harms.
