The predictive validity of the theory of Reasoned Action has been examined in numerous studies that have previously served as literature for at least three quantitative reviews. Ajzen and Fishbein (1973) reviewed 10 studies and reported a .63 average correlation for the prediction of behavior from intentions and a mean multiple correlation of .76 for the equation predicting intentions from both attitudes and norms. With similar objectives but larger samples, Sheppard et al.'s and van den Putte's meta-analyses estimated correlations of .53 and .62 for the prediction of behavior and multiple correlations of .66 and .68, respectively, for the prediction of intentions.van den Putte, B. (1991). 20 years of the theory of reasoned action of Fishbein and Ajzen: A meta-analysis. Unpublished manuscript. University of Amsterdam, Amsterdam, the Netherlands All these studies have reflected the strong correlation that exists between people's attitudes, social norms and their intentions, as well as between their intention and the prediction of their behaviors. However, these correlations do not remain unchanged across all the conditions in people's life. Although people are likely to develop intentions to perform the action in question if they have a favorable attitude and perceive the behavior as controllable, then people's perception of control would be irrelevant to intentions when people have negative attitudes and perceive normative pressure not to perform certain actions. Research has also shown that people are more likely to perform an action if they have previously formed the corresponding intentions. Their intentions to perform the action appear to derive from attitudes, subjective norms, and perceived behavioral control. For instance, the reason you are motivated to have a few drinks after work is mostly determined by several factors . The very first one is your intention. Whether you have a positive attitude towards drinking as it can help you relieve stress and enjoy your timecan greatly influence your attitude towards drinking after work. The next factor is the subjective norms around you. The level of intention to drink after work you are most likely to develop is influenced by whether significant people around you also hold favorable attitudes towards drinking and whether society tends to reward people who can drink. The last factor is the level of perceived behavioral control you have towards your intended behavior, more specifically how much confidence you have in controlling how much you will drink. If all of these factors tend to enhance your intention to have some drinks after work, you are more likely to do so. The longer you maintain the behavior of drinking after work, the stronger and more consistent your original intention will become. As a result, the greater the likelihood you will have some drinks in the future .

To state an example: The reason one may be motivated to consumate alkohol after work is determined by several factors : (1) Intention. The idea that drinking can help an individual relieve stress and enjoy one's time, for example, can greatly infleunce the attitude towards post-work drinking. (2) Subjective norms in one's surroundings. This factor is mainly cultural, so how much a society values and rewards drinking, but also strongly influenced by one's immediate social circle's values about this specific issue. (3) Perceived behavioural control towards the intended behaviour, specifically regarding the amounts of alkohol consumed. (4) Trends in behaviour. The longer the behaviour has been influenced by the previous factors, the more likely the behaviour is prone to be repeated as the original intention becomes reinforced .
