Brief Summary

Learning impairments (such as reduced selective learning or excessive generalization) in the context of pain can lead to disability. Learning deficits have been found in experimental studies in various pain populations. In current scientific discussions, the activation of resilience factors (in particular positive affect and optimism) is being considered to optimize learning experiences and to make therapeutic procedures more effective. Positive affect could promote selective learning since positive emotions broaden attention and focus and thus possibly improve inhibitory learning. There is first scientific evidence for improved safety learning through positive affect in non-clinical samples in the context of pain. In this research project, the influence of positive affect and optimism on selective learning will be investigated in a clinical sample of fibromyalgia patients. Data will be collected online and standardized questionnaires will be used. The authors expect that (1) There will be a larger increase in positive affect and positive future expectations in the Best Possible Self condition than in the Typical Day condition. (2) Patients in the Best Possible Self condition will show elevated positive affect and positive future expectations after the intervention compared to patients in the Typical Day condition. (3) And crucially, patients in the Best Possible Self condition will show better selective learning than patients in the Typical Day group. Thus the investigators hypothesize that the blocking effect will be higher for patients with higher degrees of positive affect and optimism.

Outcome Measures

Primary Outcomes (9)

  • Positive Affect

    Positive Affect will be measured with the Positive and Negative Affect Schedule (PANAS; Breyer \& Bluemke, 2016). It will be tested if participants of the BPS group score higher in Positive Affect after the intervention than at baseline. Further, we will test if participants in the BPS condition score higher in Positive Affect than participants in the TD group.

    post-intervention (immediately after the intervention)

  • State Optimism/Positive Future Expectancies

    State Optimism/Positive Future Expectancies will be measured with the future expectancies scale (FEX; Hanssen et al., 2013; Peters, Vieler, \& Lautenbacher, 2016). It will be tested if participants of the BPS group score higher in Optimism after the intervention than at baseline. Further, we will test if participants in the BPS condition score higher in Optimism than participants in the TD group.

    post-intervention (immediately after the intervention)

  • Pain expectancy/contingency awareness pre-rating phase

    Numerical Rating Scale (NRS; 0-100; 0 = expect not all, 100 = expect very much) It will be tested to which extent participants expect pain for the different stimuli which are used in the experiment (A, B, X, Z).

    Pain-expectancy will be measured in the pre-rating phase before the intervention

  • Pain expectancy/contingency awareness elemental acquisition phase

    Numerical Rating Scale (NRS; 0-100; 0 = expect not all, 100 = expect very much) It will be tested to which extent participants expect pain for the stimuli A+ and Z-.

    Pain-expectancy will be measured in the practice phase before the intervention

  • Pain expectancy/contingency awareness reminder of acquisition phase

    Numerical Rating Scale (NRS; 0-100; 0 = expect not all, 100 = expect very much) It will be tested to which extent participants expect pain for the stimuli A+ and Z-.

    post-intervention (immediately after the intervention)

  • Pain expectancy/contingency awareness compound acquisition phase

    Numerical Rating Scale (NRS; 0-100; 0 = expect not all, 100 = expect very much) It will be tested to which extent participants expect pain for the stimuli B+, AX+ and Z-.

    post-intervention (immediately after the intervention)

  • Pain expectancy/contingency awareness test phase

    Numerical Rating Scale (NRS; 0-100; 0 = expect not all, 100 = expect very much) It will be tested to which extent participants expect pain for X, B, and Z. In case of "blocked", i.e. reduced pain expectation for X in the test phase we can assume adaptive, selective learning.

    post-intervention (immediately after the intervention)

  • Positive Affect

    Positive Affect will be measured with the Positive and Negative Affect Schedule (PANAS; Breyer \& Bluemke, 2016). It will be tested if affect is stable from immediate postvisualization to end of the experiment.

    immediately after the blocking procedure

  • State Optimism/Positive Future Expectancies

    State Optimism/Positive Future Expectancies will be measured with the future expectancies scale (FEX; Hanssen et al., 2013; Peters, Vieler, \& Lautenbacher, 2016). It will be tested if state optimism is stable from immediate postvisualization to end of the experiment.

Study Arms (2)

Best Possible Self

EXPERIMENTAL

Positive affect and optimism will be induced through the Best Possible Self (BPS) Intervention. In the optimism intervention, participants will be asked to imagine a future in which everything went well and in which all their wishes are fulfilled. This procedure is known to reliably generate positive affect and positive future expectations (Carrillo et al., 2019). Orientated at Flink et al. (2015) the BPS condition was adapted for a pain population.

Behavioral: Best Possible Self

Typical Day

ACTIVE COMPARATOR

In the control condition, participants are asked to describe and visualize a typical day (TD). We adapted the TD condition in order to take possible changes in participants´ TD due to the COVID-19 pandemic into account.

Behavioral: Typical Day

Interventions

Participants are asked to think about their Best Possible Self for one minute, then describe it for 15 minutes (in writing) and, subsequently, imagine it for another 5 minutes as vividly as possible.
