Regarding the article ‘The role of attachment in recovery after a school-shooting trauma’ by Tuija Turunen, Henna Haravuori, Raija-Leena Punamäki, Laura Suomalainen and Mauri Marttunen

Two errors were noticed in this article:
1) The measure part concerning Impact of Event Scale is incorrect
2) In Table 4, the stars indicating the beta-values at time point T3 are missing from the Secure-avoidant regression analysis after beta values IES-total (value .21), IES-intrusive (.21) and IES-hypoarousal (value .22)
The correct paragraph and table are displayed below.
Posttraumatic stress symptoms were measured by the Impact of Event Scale (IES) by Horowitz, Wilner, and Alvarez (1979) version IES-22 that consists of 22 questions on posttraumatic symptoms. Participants estimated items on scale 0=not at all, 1=rarely, 3=sometimes, and 5=often, based on their experiences during the previous week. The sum variables were formed depicting intrusive, avoidant, and hyperarousal symptoms. Sum scores for the total scale and the three subscales were calculated at T1, T2, and T3 and used as continuous variables. Good internal consistency among the total scale and the subscales was observed. Cronbach's α for the total PTSD symptoms was 0.94, for the IES-Intrusive 0.89, IES-Avoidance 0.85, and IES-Hyperarousal 0.87 at T1 (α-values were 0.95, 0.89, 0.90, and 0.85 at T2 and at 0.95, 0.89, 0.90, and 0.88 at T3, respectively).
