- L β Findings are less representative of the target population due to sample not diverse enough
- P β The use of questionnaires
- E β Participants might give social desirability answers that exaggerates the effect of the course
- E β For example, both MBSR and control group participants completed FFMQ consisting of 39 questions twice, before and after the MBSR course
- L β Lower validity of findings as it is a subjective measure
- P β All closed-questions given to the participants
- E β Participants were forced to choose an answer, as they cannot give any elaboration
- E β For example, the FFMQ uses a five point likert scale with 1 being never or very rarely true and 5 being very often or always true
- L β The responses might not reflect their true opinion
