BASC = Behavior Assessment System for Children SDQ = Strengths and Difficulties Questionnaire, DSP = Deprivation-specific psychological patterns, m = months, y = years
This study assessed children who were still institutionalized, so duration of institutionalization was assessed rather than age at adoption
