My research focuses on measuring the neural correlates (through resting-state EEG) pre-post an improvisational music therapy session (MT sessions) in clients with substance misuse. One of my variable of interest is the urge to consume the drug = namely, craving (Volkow et al., 2015) .

I was thinking to use some subjective measure of craving pre and post the MT sessions to associate this with the pre/post resting-state EEG measures. I've been found in the scientific literature similar procedures in the work of De Ridder research group: the authors associated the subjective measures collected pre-post an experimental manipulation with the neural data (EEG) collected pre-post an experimental manipulation.

Participants will have to complete the following statement: "please, rate how strong your craving is right now by circling a number on the 10-point scale"...In which 0=not craving at all and 10=the most ever

Since craving is a complex construct that has been related to addiction memories and can be triggered by environmental cues (Chen et al., 2018; Huang et al., 2018) I am afraid to prompting them and induce a craving response during the MT session that wouldn't have happened.

Is that possible that using a self-report assessment of craving, participants are required to reflect on their experiences entailing a craving response that otherwise would have been absent?

  • $\begingroup$ This to me is a risk with self-report measures. It would be interesting to see what studies confirm such a risk and at what level. $\endgroup$ Mar 25, 2021 at 12:02
