Using a standardized sound set to help characterize misophonia: The international affective digitized sounds

Misophonia is a condition characterized by negative affect, intolerance, and functional impairment in response to particular repetitive sounds usually made by others (e.g., chewing, sniffing, pen tapping) and associated stimuli. To date, researchers have largely studied misophonia using self-report measures. As the field is quickly expanding, assessment approaches need to advance to include more objective measures capable of differentiating those with and without misophonia. Although several studies have used sounds as experimental stimuli, few have used standardized stimuli sets with demonstrated reliability or validity. To conduct rigorous research to better understand misophonia, it is important to have an easily accessible, standardized set of acoustic stimuli for use across studies. Accordingly, in the present study, the International Affective Digitized Sounds (IADS-2), developed by Bradley and Lang [1], were used to determine whether participants with misophonia responded to cert..., Group differences in sound ratings were examined using a two-way, mixed analysis of covariance (2 groups x 3 sound types, where “group” corresponds to participants with misophonia or controls, and “sound type” refers to positive, negative, or neutral sounds) on four dependent variables (ratings of valence, arousal, similarity, and avoidance). When statistically significant interactions were observed for sound type, pairwise comparisons were used to determine group differences on each dependent variable, as well as mean differences between sound type on each dependent variable.
All analyses were conducted using IBM SPSS27 statistical software. The first step in the data analytic plan included cleaning and screening the dataset by (a) inspecting all variables for data entry errors (none were observed), and (b) examining the normality of distributions across study variables. Next, bivariate correlations were explored to examine the relationships among variables and determine whether it wou..., , # Using a standardized sound set to help characterize misophonia: The international affective digitized sounds

## Description of the data and file structure

MQincluded is the group variable. MQincluded=1 describes all participants who meet misophonia criteria and were included in the dataset. MQincluded=0 describes healthy controls. All variable names for the measures have descriptors in the \"label\" column of SPSS. Average ratings for the dependent variables are found at the end of the variable view in SPSS, as well as PANAS positive and negative scores and the AIM total score.
