Measuring the effectiveness of fundraising campaigns is crucial for improving communication strategies. This is particularly pertinent for healthcare campaigns aimed at raising awareness about sensitive health issues that require financial support for advancing research efforts. The present work assesses campaign effectiveness by examining brain activation evoked by different video stimuli. Within a multivariate statistical setting, we compare the physiological responses that are induced by four fundraising campaigns designed under different communication strategies. Specifically, we model attention-related electroencephalographic (EEG) signals using graphical models to estimate partial correlation networks associated with each video campaign. These networks are then compared in terms of structure and connectivity using resampling methods. The proposed approach is flexible, allowing for the analysis of induced physiological responses at both local and global levels. It accounts for the interrelationships among collected EEG data and participants’ heterogeneity, overcoming the need to derive composite scores as is commonly done in neuromarketing research areas. The networks derived from different campaigns exhibit significantly different structures and connectivity, indicating distinct cognitive and emotional responses induced by the videos. Given its generality, our proposed approach can be applied effectively in psychological and neuroscientific research fields whenever the physiological response to affective stimuli is of interest.
