Addiction language in descending order of the number of r/selfharm users (n = 500) using each word, phrase, or concept at least once in their posts. κ = Fleiss's kappa statistic, an indicator of intercoder reliability. Interpretation of κ (from Landis & Koch, 1977) is also reported. All values of κ were significantly better than chance agreement at the P < 0.001 level. Items shown are from an a priori codebook, and no additional instances of addiction language used by at least 1% of users (n = 5) were identified in the coding process.
