Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameter is the self reported urge to stalk. Every session in the study (treatment as usual and EMDR) wil start with the question to the participant to report the urge to stalk at that very moment, thinking of their (ex)partner and what they hope to achieve in the relation with their (ex) partner. Clients will score a 11-point scale in which the zero stands for no urge and the eleven for maximum urge. A same 11-point scale will be used during the EMDR sessions to score the intensity of positive feelings. (Shapiro, 1989; Wolpe, 1982). | — |
Secondary
| Measure | Time frame |
|---|---|
| The secundary outcome of the study is to answer the question if the intensity of the reported tension, positive and/or negative, during the EMDR sessions, is correlated with the measured physiological arousal. The expectation is that the, during the EMDR sessions reported Levels of Possitive Affect (LoPA), Levels of Urge (LoU) and Subjective Unit of Distress (SUD) will correlate with the physiological arousal, in the form of reactivity in skin conductance (positive) and HRV (negative). Physiological arousal will be explorative measured with the Empatica E4 wristwatch, an instrument that measures heart rate, skin conductance and body temperature. They will wear the wristband during the whole time of te EMDR session. This method was chosen because it is the least intrusive methods of the physiological instruments in the hope it will not interfere with the decision to participate in the study. During the four EMDR sessions will the participants be asked to report the level of tension (LoPA, Level of Positive affect and SUD, Subjective Unit of Distress) and the level of urge to stalk (LoU, Level of Urge). Measurements of skin conductance and heart rate (from which the Heart Rate Variability will be calculated) will be done during all four EMDR sessions. From this data 6 correlation coefficients will be calculated between the physiological measures and the self reported data. | — |
