Confirmatory factor analyses and reliability of the modified cigarette evaluation questionnaire

Area of Science:

• Psychopharmacology
• Clinical Psychology
• Behavioral Science

Background:

• Smoking cessation treatments aim to reduce nicotine dependence.
• Understanding the reinforcing effects of smoking is crucial for developing effective interventions.
• The modified Cigarette Evaluation Questionnaire (mCEQ) assesses these reinforcing effects.

Purpose of the Study:

• To evaluate the validity and reliability of the modified Cigarette Evaluation Questionnaire (mCEQ).
• To confirm the multidimensional framework of the mCEQ in diverse clinical trial populations.

Main Methods:

• Confirmatory factor analysis was used to assess the mCEQ's structure.
• Internal consistency reliability was measured using Cronbach's alpha.
• Test-retest reliability was assessed across multiple domains and single items.

Main Results:

• Confirmatory fit indexes exceeded 0.90, supporting the mCEQ's structure.
• High reliability (Cronbach's alpha > 0.70) was found for Smoking Satisfaction and Psychological Reward domains.
• Generally good test-retest reliability (> 0.70) was observed across most mCEQ measures.

Conclusions:

• The modified Cigarette Evaluation Questionnaire (mCEQ) demonstrates strong validity and reliability.
• The mCEQ's multidimensional framework is supported by data from three independent clinical trials.
• The mCEQ is a reliable tool for assessing smoking reinforcement in clinical research.
