In the present study the psychometric properties of the Environmental Reward Observation Scale (EROS) in Colombian population were estimated with two different samples: population and clinic. For the first sample 517 people were evaluated in 22 departments of the country aged 18 to 72, 60.5% are women and the remaining men, the second sample was composed of 68 people aged between 18 and 72 years who They are served at present by mental health professionals. Based on the above, the application of the instruments (Environmental Observation Reward Scale Y Auto Scale Applied Zung Depression) was made through social networks and emails in order to have a larger sample and greater variability the same in relation to the general population. Appropriate levels of internal consistency (alpha of 0.87) and significant evidence of construct validity (grouping by a factor that explains the 46.815% of the total variance) and discriminant ( r = -0.67).
