Abstract

Objectives
The aim of this study is to assess the reliability of the Adolescent Label Impact Index (ALII) , it is an adolescent adapted version of Italian LII of the tobacco products warnings.


Material and Methods
A sample including students aged 13-15 years was considered. The ALII is constructed by 4 items: salience, harm, quitting and forgo. The questionnaire was self-administered to study participants twice with 3 days between each administration (T1 and T2) to measure reliability. The internal consistency using Cronbach’s alpha and Corrected Item—Total Correlations (CITC) and the test-retest reliability applying Pearson’s correlation were computed.


Results
Cronbach’s alpha ranges from 0.625 at T1 to 0.715 at T2. The “salience” resulted the item with the lowest CITC value (=0.281). The Pearson’s coefficient was r=0.909 (p<0.001).


Conclusions
The instruments is low in cost and easy to administer and analyses in a setting people aged 13-15 years. The ALII shown an acceptable consistency and excellent stability over time. However, attention has to be paid when the ALII is administered to the no smoking teens and who has never seen the tobacco product labels to allow an appropriate interpretation of the data collected
