Theory of Planned Behaviour


The Theory of Planned Behaviour is built out of a number of constructs. The first construct is the attitude towards the act or behaviour. That is, an individual’s belief of whether a certain behaviour or act makes a positive or negative contribution to that person’s life.

A second construct is called subjective norm. This construct focuses on everything around the individual. In other words his or her social network, cultural norms, group beliefs and so on.

A third construct is called perceived behavioural control. This construct refers to a person’s belief of how easy or hard it is to display a certain behaviour or act in a certain way.

We can use the theory to predict that if a person has a positive attitude towards an act or behaviour, and they are surrounded by favourable social norms and they have a high level of perceived behavioural control, these are the best predictors for forming a behavioural intention and in turn, they will lead to the person actually displaying the behaviour or act.

  1. I missed the class for this topic in class and I went to my professor asking her to give me some of her time and if she could explain the topic since both her and I didn’t have any class. She just sipped her tea and said “you missed it it’s gone then you are on your own” . I can’t believe such attitude is so common in my current college. But am glad I found this video

  2. Hello dear,
    Whether TPB cover uncertain situation like in case of any robbery, fight or accident etc what we react can cover by TPB factors.

  3. There are different points in our lives that we look into implementing changes that will have an overall effect on our lifestyle and will change not only one but different aspects of our life. For me, implementing the stages of change at an early age helped me accomplish more than I ever thought I could. For starters, I can relate to Isabella and know what it feels like to be frustrated and stressed out because I am not able to accomplish my goal and have quit before I make it to the finish line. For me, the turning point was when I pregnant with my son and I knew that I wanted to finish college so that I can give him the type of life he deserved. It was hard trying to work and attend school full time while being pregnant, but with support of my family and being organized I was able to finish college before my son turned two. Now, I find myself in the same situation but I am once again determined to finish my master’s degree and have passed the determination stage and I am currently taking action while being consistent in maintaining my goal of graduating while working full time, raising a 5 year old, and going through my second pregnancy. It is not impossible, but it takes a lot of determination, sacrifice, understanding of the big picture, and the right support system.

  4. This is how you teach PERIOD
    Too many professor just throw verbal diarrhea and expects you to learn. Good job on the video, I really like your teaching style. Many professors can learn something from you.
