The materials to collect the data for the survey were digitally distributed among the respondents such as the online questionnaire by campus mail, email invitations and reminder. In addition, a small scaled focus group discussion was held and supporting materials were handed manually.

Adjustments to the raw data file
Data was collected among students from a University of Applied Sciences. The survey study consisted of two parts. The focus of this study is on Relationship Quality dimensions. Next to quantitative survey data on relationship quality dimensions, we collected critical incidents to measure students' perceptions of relationship quality examples, however, they are not included in the data-analysis of this study.
To conduct a confirmatory analysis on the quantitative data, we had to make some adjustments to the raw data file:
- variables that did not were included in the study were excluded from the analysis;
- All respondents that did not filled out the questionnaire completely and/or did not seriously filled out the questionnaire e.g., all had the same score on every item, were removed from the dataset;
- Negative formulated items were recoded if necessary for the analysis;
- Descriptive statistics- and frequencies were checked for irregularities;
- Difference analysis was conducted to confirm the A/B-version questionnaire influenced outcomes. Independent samples t-test was used. No significant differences were found.
