The purpose of this study was to investigate whether the meaning reconstruction can be predicted by attachment style among adults who experience bereavement during adolescents. The attachment style scale and the integration of stressful life experience scale were used in this study. Five hundred and sixty-seven subjects were recruited by purposively sampling method. The means of meaning reconstruction by different social economic status variable were compared by independent sample t-test and one way ANOVA. The hierarchical regression method was used to examine the effect of attachment style on the meaning reconstruction after controlling background variables. The results were concluded as follows: (a) Female’s mean of meaning reconstruction is significantly higher than male’s. (b) People who suffered the death of grandparents, cousin, or pets have significantly higher mean scores of meaning reconstruction than people who suffer the death of parents. (c) There were no differences found on the means of meaning reconstruction by the bereavement from time. (d) People who suffered anticipatory bereavement have significantly higher mean scores of meaning reconstruction than those who suffered non- anticipatory bereavement. (e) People who suffered diseases bereavement have significantly higher mean scores of meaning reconstruction than those who suffered accident bereavement. (f) People who normal and un-intimate of deceased have significantly higher mean scores of meaning reconstruction than those who is intimate or very intimate of deceased. (g) There was no significantly effect of religions on the mean of meaning reconstruction. (h) People with secure attachment style have higher mean scores on meaning reconstruction than those with insecure attachment style. (i) The attachment style can significantly predict the meaning reconstruction. Future research directions and recommendations for practical work are discussed.
