This study aimed to develop affective norms for Persian attachment related words in three phases. In the first phase, 72 students (43 female, 29 male) of Shahid Beheshti University were selected to collect attachment related words. In the second phase, 35 attachment specialists (27 female, 8 male) in Tehran, were chosen to evaluate attachment relevance of words. In the last phase, 124 students (65 female, 59 male) of Shahid Beheshti University were chosen and they rated selected words respect to emotional dimensions through Self-Assessment Manikin (Bradley & Lang, 1994) and attachment relevance. Pearson correlation coefficient and mixed ANOVA were used for analysis. After several phases of screening, 107 attachment related words were collected and we presented their emotional dimensions in a descriptive manner. Results showed that attachment relevance has a positive correlation with valence and negative correlation with arousal. There was a negative relationship between valence and arousal. Although females had a positive and negative bias in valence rating of respected words, there was no significant gender difference in arousal. The set of words that was prepared in this study can make the replication of results and scientific communication easier and provides the possibility of comparing results of different studies especially in the field of attachment.
