3

Explain your conceptualization of PL and refer to a holistic definition of PL

4

Formulate PL-related goals/aims of your study

ASSESSMENT

5a

If quantitative: Choose a multidimensional assessment strategy of PL and provide information about psychometric properties

5b

If qualitative: Develop a qualitative method that closely aligns with PL theory and the different domains

DESIGN AND CONTENT

6

Ensure that your interventional approach is in line with PL-compatible philosophical assumptions

7

8

Report in detail intervention content related to all PL domains

If quantitative: Report transparently how the different PL domains (and, if initially intended, other relevant outcomes such as health) were affected by the intervention

12b

If qualitative: Characterize the strengths, weaknesses, and challenges of your PL intervention; the different PL domains may help you structure the analysis and results

DISCUSSION AND CONCLUSION

13

Discuss the limitations of your PL intervention, especially whether (if yes, where and why) you had to deviate meaningfully from your planned conceptualization

14

Break down your experiences with the PL intervention and derive sound recommendations for future studies
