“…Although, to our knowledge, this was the first study to explore semantic themes in psychosocial interventions using Wmatrix, other recent developments in automatic text analysis are gaining momentum in psychology. Topic models (or Latent Dirichlet Allocation, LDA; Griffiths & Steyvers, 2004) have recently gained popularity as a data-driven method for quantifying the semantic dimensions in texts and have recently been used to investigate, among other things, language patterns on Facebook and Twitter (e.g., Dehghani, Sagae, Sachdeva, & Gratch, 2014; Eichstaedt et al, 2015; Kern et al, 2014; Schwartz et al, 2013 ). In the clinical context, Atkins, Rubin, Steyvers, Doeden, and Baucom (2012) used topic models to empirically characterize common themes brought up in couple therapies for relationship distress, such as family, finances, and sex, as well as topics specific to different treatment modalities.…”
