Method: Premorbid adjustment was assessed using Premorbid Adjustment Scale (PAS) in 48 patients with the first psychotic episode who were admitted to Roozbeh Psychiatric Hospital. The severity of symptoms was measured using Positive and Negative Scale (PANSS) in three subgroups of positive, negative and general subscales. Quality of life was measured using WHO QOL ,and Global Assessment of Functioning (GAF) was also measured. Results: The mean age was 24 years. Poor Premorbid adjustment in late adolescence  was  significantly  associated with  more  severe  symptoms according  to  PANSS  negative symptoms  (p=0.019,  r=0.44).  Furthermore, sociability  and  peer  relationship  domains  had  a  positive  correlation  with PANSS negative subscale scores (r=0.531, p=0.002 and r=0.385, p=0.03, respectively).  There  were  no  significant  differences  between  males  and females in premorbid adjustment. Furthermore, this study failed to show any differences  between  affective  and  non-affective  psychosis  in  premorbid functioning. Conclusion: Our study confirms poor premorbid adjustment association with more  severe  negative  symptoms  and  poor  quality of  life in  a sample of Iranian first episode psychotic patients. https://ijps.tums.ac.ir/index.php/ijps/article/view/379 https://ijps.tums.ac.ir/index.php/ijps/article/download/379/375
