The diagram presents a structural equation model connecting psychological constructs influencing behaviour. Attitude, subjective norm, perceived behavioural control, and moral obligation predict behavioural intention, which in turn affects actual behaviour. Standardised path coefficients are shown along each arrow, with behavioural intention having the highest central effect. Each construct includes observed variables such as A T T 1 to A T T 4 for attitude, S N 1 to S N 4 for subjective norm, and A B 1 to A B 5 for actual behaviour, demonstrating reliability and internal consistency.
