Precise guidance regarding measurement
Help interventions focus on most important factors

|
Term
| Five limitations of TRA and TPB |
|
Definition
TRA/TPB predict intention (and relationships among beliefs, intentions, & behaviors) but don’t necessarily explain behavior change.
Do not consider personality-related factors, cultural factors, or demographic variables that also shape behavior
Provide precise definitions for measurement of constructs (one of the best) but less guidance for specific behavior modification
Focus only on rational thoughts and do not consider irrational thoughts or fears
Intervention messages may change one belief in the desired direction while adversely affecting another belief |
