The antecedents to the behaviour. What happens before - triggers - the behaviour that you are trying to change? Are there situations, events or feelings that make your undesirable behaviour more likely to happen? Are there conditions (situations, events, feelings) that encourage the desirable behaviour, that make it more likely to happen?

The consequences that follow the target behaviour. What you are getting out of this behaviour? Why are you doing it? Thus, you need to identify the good outcomes that keep you doing the undesirable behaviour, and/or the bad outcomes of your desirable behaviour that discourage you from doing it.

The frequency of the target behaviour - how often or how much time do you spend doing it?
