Spanish adaptation of the Environmental Reward Observation Scale (EROS)

In this paper we present the Spanish adaptation of the Environmental Reward Observation Scale (EROS). Based on theories that outline the relationship between environmental reward and mood - starting point of modem Behavioral Activation treatments for depression-, Armento and Hopko (2007) developed the EROS, a brief self-report measure designed to obtain efficient, reliable and valid information on the amount and availability of environmental reward. We analyse the psychometric properties of the Spanish adaptation using a sample of 263 clinical and nonclinical participants. Results suggest that, as the English original scale, the Spanish EROS is internally consistent (α = .86) and valid (high correlations with BDI-II, BADS, STAI-E/R, AAQ; significant differences between clinical and nonclinical participants). The current adaptation offers Spanish-speaking clinical psychologists and researchers a highly practical instrument designed to gather information on environmental reward, as perceived by an individual, and any possible changes produced as a consequence of therapeutic intervention.
