What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Placebo nasal sprayOther
Film SequenceOther
| Study group | Role | What they receive |
|---|---|---|
| Positive placebo group | Experimental | Participants receive a nasal spray that is a placebo. However, they are told that it protects from experiencing negative emotions. Participants watch a film sequence that is supposed to induce sadness. Receives: Other: Placebo nasal spray; Other: Film Sequence |
| Negative placebo group | Experimental | Participants receive a nasal spray that is a placebo. However, they are told that it sensitizes for experiencing negative emotions. Participants watch a film sequence that is supposed to induce sadness. Receives: Other: Placebo nasal spray; Other: Film Sequence |
| Placebo control group | Placebo comparator | Participants receive a nasal spray that is a placebo and are told that it is a placebo. Participants watch a film sequence that is supposed to induce sadness. Receives: Other: Placebo nasal spray; Other: Film Sequence |
| No-treatment control group | Other | Participants do not receive the nasal spray. Participants watch a film sequence that is supposed to induce sadness. Receives: Other: Film Sequence |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sadness (PANAS-X)
Measured: Directly after watching the film sequence, no follow-up assessments
