Independently of treatment group, patients were found to overall improve in terms of general symptoms and clinical severity (SCL-90-R; CGI; CGI-M 9 items), global functioning (GAF), and control of anger expression (STAXI) at T6 and T12.
Not only the frequency of anger expression, but also the way one's own anger appears can be extremely variable.
In terms of anger expression, there have been fewer investigations into the physiological responses to both A.O. and A.I. expression styles.
With respect to anger, it should also be stressed that we studied only trait anger as a personality variable, not modes of anger expression (anger-in, anger-out, cf. [ 9]), which are considered aspects of affect regulation.
Further studies are required to confirm the effect of anger expression on psychological distress.
Other dimensions of anger expression such as anger control and the effects on targets of anger such as classmates, teachers, parents, and siblings should be studied in further studies.
The internal consistency reliability for the questionnaire categories are as follows: of Anger Expression 0.89, of Hostile Outlook 0.79, of Positive Coping Anger Expression 0.66 and of Destructive Expression 0.71.
*in the year before recruitment in the study SCL-90-R Tot = Symptom Checklist 90 - Revised, Total score; CGI Item 1 = Clinical Global Impression; GAF = Global Assessment of Functioning; AX-EX = anger expression (STAXI).
Clinical Global Impression (CGI) and CGI-modified (CGI-M) for BPD, Global Assessment of Functioning (GAF), State-Trait Anger Expression Inventory (STAXI), and Symptom Checklist-90 Revised (SCL-90-R) were administered at T1, T3, T6, T12, T18 and T24.
Interaction among the dimensions of anger and anger expression style is of particular interest in the current research.
