CHANGE IN SELF‐IMAGE AND PTSD SYMPTOMS IN SHORT‐TERM THERAPIES WITH TRAUMATIZED REFUGEES

In this study, an attempt was made to evaluate changes in the self‐image of traumatized refugees receiving short‐term psychotherapy. Fourteen clients with war and torture experiences were followed during and after trauma‐focused therapies with self‐rating instruments. Outcome was measured with SCL‐90, measuring overall psychiatric symptoms, and with PTSS‐10, measuring Post‐traumatic Stress Disorder (PTSD) symptoms. Self‐image was measured with Structural Analysis of Social Behavior (SASB). The analyses showed considerable remission of both general psychiatric and PTSD‐related symptoms, but more moderate changes in self‐image aspects. The positive aspect of the self‐image was virtually non‐related to the symptom measures and did not change after the termination of the therapy; the negative aspect of the self‐image was more strongly related to the symptoms and changed mainly on the last measurement occasion, 15 months after the therapy end. When clients with good and poor outcome were compared, it was found that those with good outcome had higher initial levels on both the positive and the negative aspects of the self‐images. This was tentatively interpreted as indicating that clients who had invested more energy in their self‐image were better able to utilize the therapy. Different development in the self‐image for these two groups indicated that for some clients, the treatment process might have entailed too much strain.     

Another way to think about psychological change: experiential vs. incremental

The traditional pre-post treatment difference reflects an incremental notion of change, where a quantity of some psychological function is added to (or subtracted from) a pretreatment quantity. This study presents a complementary, experiential notion of change. Rather than a difference, change is a feeling or experience of having changed, a feeling that one is different than before. Based on a post-treatment interview the Change after Psychotherapy (CHAP) is a method to quantify/rate such ‘differentness’ in terms of how extensively or radically the patient feels having changed. A pre-post quasi-experimental study (N = 49) comparing the CHAP with ratings on the Global Assessment of Functioning, the Karolinska Psychodynamic Profile and the Comprehensive Psychopathological Rating Scale-Self-Affective is reported. The results showed the CHAP to be a reliable, valid and sensitive way to assess an experiential kind of CHAP.     

The use of control groups in artificial grammar learning

Experimenters assume that participants of an experimental group have learned an artificial grammar if they classify test items with significantly higher accuracy than does a control group without training. The validity of such a comparison, however, depends on an additivity assumption: Learning is superimposed on the action of non-specific variables—for example, repetitions of letters, which modulate the performance of the experimental group and the control group to the same extent. In two experiments we were able to show that this additivity assumption does not hold. Grammaticality classifications in control groups without training (Experiments 1 and 2) depended on non-specific features. There were no such biases in the experimental groups. Control groups with training on randomized strings (Experiment 2) showed fewer biases than did control groups without training. Furthermore, we reanalysed published research and demonstrated that earlier experiments using control groups without training had produced similar biases in control group performances, bolstering the finding that using control groups without training is methodologically unsound.
