Not Applicable

Completed

• Conditions: Experimental Group 1 (Video Personal Expert); Control Group; Experimental Group 2 (Video Factual Expert)
• Interventions: Behavioral: Progressive Muscle Relaxation (PMR)

• Registration Number: NCT03330431
• Lead Sponsor: Philipps University Marburg Medical Center

Brief Summary

The study's aim is to determine whether a short video aiming to optimize expectations regarding the effectiveness of progressive muscle relaxation (PMR) ist able to improve the actual effectiveness of PMR in comparison with a neutral (no video) control group.

Arm && Interventions

Group	Intervention	Description
Control group	Progressive Muscle Relaxation (PMR)	Participants read a neutral text before undergoing a Progressive Muscle Relaxation (PMR) session.
Experimental group 1 (personal expert)	Progressive Muscle Relaxation (PMR)	Participants watch a video of an expert describing the positive effects of Progressive Muscle Relaxation (PMR) with personalized examples and stories before undergoing a PMR session.
Experimental group 2 (factual expert)	Progressive Muscle Relaxation (PMR)	Participants watch a video of an expert describing the positive effects of Progressive Muscle Relaxation (PMR) with factual information (not personal) before undergoing a PMR session.

Primary Outcome Measures

Name	Time	Method
Change in perceived/subjective relaxation	Change from pre (baseline) to post scores (30 minutes later)	Participants are asked to rate how relaxed they feel at the moment at two time points (baseline and after the PMR intervention) on a questionnaire (VAS: item ranges from 0 (not relaxed at all) - 100 (very relaxed). Change scores are calculated (post- minus pre-scores).

Secondary Outcome Measures

Name	Time	Method
Change in physiological relaxation	Change from pre (baseline) to post scores (30 minutes later)	Electromyography is used to assess participants' physiological relaxation status at baseline and after the PMR intervention. Change scores are calculated (post- minus pre-scores).
Change in perceived stress	Change from pre (baseline) to post scores (30 minutes later)	Participants are asked to rate how stressed they feel at the moment at two time points (baseline and after the PMR intervention) on a questionnaire (VAS: item ranges from 0 (not stressed at all) - 100 (very stressed). Change scores are calculated (post- minus pre-scores).
