The initial conceptual model displaying the causal relationship based on the basic psychological needs theory.
Relatedness is here divided into two dimensions, connectedness and encouragement. The intervention was not thought to increase autonomy, so this dimension is absent from this diagram.

Overview of the research questions (RQs) and hypotheses (Hs) considered in this study.
Table 2.
Simple causal mediation analysis for control vs. puzzle for each dimension of experience.
The a-path corresponds to the influence of the predictor (i.e. interview mode) on the mediator variable. The b-path corresponds to the influence of the mediator variable (e.g. competence) on the outcome.
Table 3.
Multiple causal mediation analysis for control vs. puzzle for each dimension of experience.
The a-path corresponds to the influence of the predictor (i.e. interview mode) on the mediator variable. The b-path corresponds to the influence of the mediator variable (e.g. competence) on the outcome.
Table 4.
Simple causal mediation analysis for control vs. able to do the puzzle (PUZ+) for each dimension of experience.
The a-path corresponds to the influence of the predictor (i.e. interview mode) on the mediator variable. The b-path corresponds to the influence of the mediator variable (e.g. competence) on the outcome.

Multiple causal mediation analysis for control vs. able to do the puzzle (PUZ+) for each dimension of experience.
The a-path corresponds to the influence of the predictor (i.e. interview mode) on the mediator variable. The b-path corresponds to the influence of the mediator variable (e.g. competence) on the outcome.
Table 6.
Simple causal mediation analysis for control vs. not able to do the puzzle (PUZ-) for each dimension of experience.
The a-path corresponds to the influence of the predictor (i.e. interview mode) on the mediator variable. The b-path corresponds to the influence of the mediator variable (e.g. competence) on the outcome.
