AB  - OBJECTIVES: The purpose of the following study was to verify the psychometric 
      properties of the Polish version of the Inventory of Complicated Grief. METHODS: 
      278 people who experienced loss of a close relative or a friend participated in 
      the research on adaptation of the tool. The following research methods were 
      applied: ICG (Inventory of Complicated Grief), BDI (Beck Depression Inventory), 
      STAI (State-Trait Anxiety Inventory), IES-R (Impact of Events Scale-Revised), AHS 
      (Adult Hope Scale), LOT-R (Life Orientation Test-Revised), GSES (General 
      Self-Efficacy Scale), MSTAT-2 (Multiple Stimulus Types Ambiguity Tolerance). 
      RESULTS: The statistical analyses conducted as part of the research prove the 
      Polish version of the ICG to be a reliable and valid tool (Cronbach's alpha = 
      0.941). Amoderate positive correlation was noted between the overall ICG score 
      and depression (r = 0.50; p < 0.001), post-traumatic stress disorder (r = 0.67; p 
      < 0.001) and trait anxiety (r = 0.59; p < 0.001). The general ICG results also 
      display negative correlation between variables related to positive expectations 
      of the future: optimism (r = -0.37; p < 0.001), hope for success (r =-0.19; p 
      =0.001), general self-efficacy (r = - 0.27; p < 0.001), and ambiguity tolerance 
      (r = - 0.27; p < 0.001). The conducted confirmatory factor analysis (CFA) 
      revealed that the one-factor model of the Polish version of the Inventory of 
      Complicated Grief can be considered wellfitted to the data (correlation of 
      measurement errors was allowed). CONCLUSIONS: Preliminary studies on the 
      adaptation of the Polish version of the ICG prove, therefore, that it is a valid 
      and reliable tool. However, further research is needed to help better understand 
      the structure of complicated grief symptoms.
