Abstract
The Transitional Impact Scale (TIS) was developed by Svob, Brown, Reddon, Uzer, and Lee (2014) to measure the quality and quantity of changes brought about by transitional events. The aim of the present study was to investigate the psychometric properties of the TIS. Study 1 investigated the validity and internal consistency of the TIS among 445 participants (aged 18–73 years) who completed the TIS, Beck Anxiety Inventory (BAI), Centrality of Event Scale (CES), Impact of Event Scale‐Revised (IES‐R), and Post Traumatic Growth Inventory (PTGI). Study 2 investigated the test–retest reliability of the TIS among 140 university students (70 female; 70 male) who completed a re‐test of the TIS after a 2‐week interval. The two‐factor structure (i.e., material change and psychological change) of the TIS proposed by Svob et al. (2014) was confirmed in different age and SES groups of a Turkish sample. The TIS was significantly correlated with the Beck Anxiety Inventory (BAI), Centrality of Event Scale (CES), and Impact of Event Scale‐Revised (IES‐R). Finally, the TIS had a high test–retest reliability.
