***General introduction***
This dataset contains data collected directly after physical education lessons in secondary schools in the Netherlands. This data collection was part of Christa Krijgsman's PhD research (https://dspace.library.uu.nl/handle/1874/401403).
The PhD project was supported by the Netherlands Organisation for Scientific Research (Grant 023.004.015), the Netherlands, and by the Association Ons Middelbaar Onderwijs, the Netherlands.

***Research questions that guided this study***
The following research questions (RQ) guided the present study: 
1: Which subpopulations of students, characterized by different combinations of need-based experiences, exist in the present sample, taking into account the global and specific levels of their need-based experiences? 
2: To what extent is the pattern of subpopulations of students, and students’ individual membership in specific profiles, stable over time?
3: How is membership to a specific profile associated with students’ autonomous motivation, controlled motivation, and amotivation?

***Analyses conducted***
All analyses were conducted in MPlus. In the corresponding manuscript and supplement to the manuscript, we describe which analyses we conducted and why.

Preliminary analyses:
- We estimated preliminary measurement models to verify the factor structure and the longitudinal measurement invariance (i.e., measurement equality over time). 
- To do so, we used all analyses code filed under the name '1 meas mod...' (measurement models). NS = need satisfaction; NF = need frustration; MOT = motivation.

Analyses conducted to answer RQ 1 and 2: 
Latent profile (LPA) and latent transition analyses (LTA):
- LPA class enumeration:
- We used all analyses code filed under the name '2 class enumeration...'
- Profile similarity:
- We used all analyses code filed under the name '3 profile similarity...'
- Transitions:
- We used all analyses code filed under the name '4 transitions...'

Analyses conducted to answer RQ3:
Outcomes of profile membership:
- Outcomes autonomous motivation, controlled motivation, and amotivation
- We used all analyses code filed under the name '5 outcomes...'
