Drawing and Anxiety Study: Investigation of a Guided-Drawing and Mindfulness Intervention to Reduce Anxiety

Materials The Screen for Adult Anxiety Related Disorders (SCAARED) is a 44-item self-report questionnaire designed for screening anxiety disorders in adulthood. Factors assessed include generalized anxiety disorder (GAD), social anxiety disorder (SAD), separation anxiety disorder, and somatic/panic/agoraphobia. Items include statements such as 'I worry about people liking me', 'People tell me that I look nervous', 'I am afraid to be alone in the house', and 'When I get anxious, I feel dizzy'. Participants indicate their response on a 3-point scale (0 = not true or hardly true ever, 1 = somewhat true or sometimes true, 2 = very true or often true). Higher scores indicate a higher likelihood of anxiety disorder(s).

State-Trait Anxiety Inventory - State Scale. The State-Trait Anxiety Inventory - State Scale (STAI-S, Spielberger et al., 1983) is a 20-item self-report questionnaire designed to assess state anxiety (current anxiety feelings). Items include statements such as 'I feel calm', 'I feel strained', and 'I am jittery'. Participants indicate their response on a 4-point scale (1 = not at all, 4 = very much so). Higher scores indicate greater state anxiety.

Participants are also asked to report on their emotion regulation difficulties as an individual difference moderator variable. The Difficulties in Emotion Regulation Scale - Short Form (DERS-SF) is an 18-item self-report questionnaire designed for assessing emotion regulation problems. Items include statements such as 'I care about what I am feeling', 'When I'm upset, I have difficulty focusing on other things', and 'When I'm upset, it takes me a long time to feel better'. Participants indicate their response on a 5-point scale (1 = almost never, 5 = almost always).

Cardiac Activity Recording and Data Processing Electrocardiogram (ECG) data was recorded using Mindware software with a sampling rate of 500 ms. Three electrodes were applied to the participants: on the distal right collarbone, the lower left rib, and the lower right rib to acquire the electrocardiogram (ECG) signal.

Experimenters manually mark the beginning and end of each episode in the cardiac data using Mindware's BioLab software. During the session, markers are placed to indicate the onset and offset of the pre-drawing period (8 minutes), the drawing session (~20 minutes; guided drawing or controls), and the post-drawing period (8 minutes). During the pre-drawing and post-drawing periods, participants complete state questionnaires (~2-3 minutes) and then remain seated until a total of 8 minutes elapsed.
