NCT03330431

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.

Outcome Measures

Primary Outcomes (1)

  • Change in perceived/subjective relaxation

    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).

    Change from pre (baseline) to post scores (30 minutes later)

Secondary Outcomes (2)

  • Change in perceived stress

    Change from pre (baseline) to post scores (30 minutes later)

  • Change in physiological relaxation

    Change from pre (baseline) to post scores (30 minutes later)

Study Arms (3)

Experimental group 1 (personal expert)

EXPERIMENTAL

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.

Behavioral: Progressive Muscle Relaxation (PMR)

Experimental group 2 (factual expert)

EXPERIMENTAL

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.

Behavioral: Progressive Muscle Relaxation (PMR)

Control group

ACTIVE COMPARATOR

Participants read a neutral text before undergoing a Progressive Muscle Relaxation (PMR) session.

Behavioral: Progressive Muscle Relaxation (PMR)

Interventions

All groups undergo a PMR session, but they differ regarding the treatment before the PMR session. Two groups watch a video before undergoing PMR, the control group reads a text before undergoing PMR. Progressive muscle relaxation (PMR) is a technique for learning to monitor and control the state of muscular tension. It was developed by American physician Edmund Jacobson in the early 1920s. The technique involves learning to monitor tension in each specific muscle group in the body by deliberately inducing tension in each group. This tension is then released, with attention paid to the contrast between tension and relaxation.
