item. There were four response categories for each of these 20 items which were scored as follows: *to a greater extent* equals 3*; to some extent* equals 2; *to little extent* equals 1; and *not relevant* equals 0. The internal consistencies of the three factors using Cronbach's alpha methods were as follows: alpha~PE~ = 0.48; alpha~TR~ = 0.74; and alpha~SP~ = 0.62. To assess the impact of each factor on drinking habits, each item in each of the three subscales were added up to obtain 3 subscale scores.

2.3.. Data Analysis
-------------------

The collected data were checked for consistency. Descriptive and bivariate analyses of the data set were done using SPSS 15.0 \[[@b20-ijerph-06-02408]\]. Confirmatory Factor Analysis (CFA) of the 20 item motives scale toward alcohol use was conducted using Lisrel 8.80 \[[@b21-ijerph-06-02408]\].

3.. Results
===========

After cleaning and consistency checking, analysis was done using 412 sample subjects. The age of the participants ranged from 16--30 years (*M = 20.27*, *SD = 3.63*). Forty-eight participants (11.7%) were married. Of the total, 102 (24.8%) had a job at the time of the survey and the others were either students or unemployed. Nine participants (2.2%) were daily users, 33 (8%) use alcohol 2--3 times a week, 76 (18.4%) 2--3 times a month and the remaining 294 (71.4%) 2--3 times a year. Means, standard deviations, and correlations among subscales and total scale are provided in [Table 1](#t1-ijerph-06-02408){ref-type="table"}.

Correlations among subscales and total scale ranged from 0.28 to 0.90 (*p \< 0.01*). The strongest association was found between tension reduction and total score, and a relatively weaker association was found between personal enjoyment and social pressure.

3.1.. Confirmatory Factor Analysis (CFA)
----------------------------------------

The 3-factor structure of the scale *motivations towards alcohol use* was tested using Lisrel 8.80. All indicators in the model had loadings above 0.40 and were significant at the *p \< 0.01* level (
