Thus, these results confirm our first hypothesis H1a, which states that high scores on the cognitive determinant attitude in favour of alcohol use, and low scores on subjective norm not to use alcohol and self-efficacy not to use alcohol predict high scores on adolescent intention to drink alcohol. There was no significant correlation between the variable intention to binge drink and the age of first alcohol consumption.

The siblings’ age of first alcohol consumption showed no significant correlation with the adolescents’ frequency of binge drinking and usually consumed number of glasses. On a significance level of alpha = .01, adolescents’ age of first alcohol was significantly correlated with the siblings’ age of first alcohol use. The siblings’ frequency of binge drinking and the siblings’ usually consumed number of glasses were highly significantly and positively correlated with the adolescents’ frequency of binge drinking and usually consumed number of glasses. The siblings’ alcohol favouring behaviour was also positively correlated with adolescents’ frequency of binge drinking and usually consumed number of glasses, on a
