The study assessed the efficacy of a virtual reality biofeedback video game (DEEP) in reducing anxiety symptoms. In addition, engagement and cognitive appraisals including self-efficacy, locus of control, and threat-challenge  were explored as potential mechanisms of change. Undergraduates with elevated anxiety symptoms (N = 112) were randomly assigned to four training sessions in the lab with either DEEP, a biofeedback video game,  or a smartphone-guided breathing application. Trait anxiety was measured at screening (two weeks prior to the training), pre-test, post-test, and three months later. State anxiety was assessed before and after each individual training session. Engagement as well as all cognitive appraisals were assessed after each training session.</p><p>This repository includes the following files:<br>- A word file which describes the complete method and procedure of the corresponding Randomized Controlled Trial study, including a description of how the data was analysed.<br>- Two data-sets(one in .sav and one in .CSV format) with all the data that was reported on in the corresponding article, including<br>raw data of participant characteristics and single-item questions as well as the sum-scores, ratio-scores or difference scores of the main outcomes.<br>- A data codebook (in .xlsx format) including a description of of the variables in the data-set including the labels, values and the scales of the corresponding questionnaire items.</p><p>Information regarding missing values:<br>Missing values on the variables 'gamehrswk' and 'gamehrswknd' are the result of these questions being skipped because participants answered 'No' on a previous question asking whether or not they play video games (variable 'doyougame').<br>Missingness on other values was due to participants dropping out of the training or not filling out the online follow-up questionnaire.
