Treatment groups
Trial outcomes
Primary outcomes
Measuring pain by computerized Visual Analog Scale Scoring
We will ask the subjects to rate the sensation of pain on a 100
Secondary outcomes
Pain Catastrophizing Scale (PCS).
The PCS assesses negative and exaggerated coping concerning anticipated or experienced painful stimuli. Thirteen items have to be answered on a 5-point Likert-type scale ranging from 0 (Not at all) to 4 (all the time).
Learned Helplessness Scale (LHS)
The questionnaire consists of 20 items, and the participant's response to each item is rated on a 4-point Likert scale branging from strongly agree (1) to strongly disagree (4).
Depression, Anxiety, Stress Scale (DASS-21)
The questionnaire measures the magnitude of depression, anxiety, and stress. Each of these three subscales consists of 7 questions answered using a 0-3 Likert scale, with 0 meaning "it did not apply to me", and 3 meaning "it applied to me very much"
Reinforcement Sensitivity Theory - Personality Questionnaire (RST-PQ).
The RST-PQ contains in total 65 items must be answered on a Response scale: 4-point Likert (Strongly disagree → Strongly agree).
