The influence of current stress on dissociative experiences: an exploratory study in a non-clinical population.

In this study, the relationship between current stress, as perceived by an individual, and dissociative phenomena is explored. All subjects were in an acute and naturally caused stress-situation-sudden threat of dismissal from their jobs in a large multinational corporation. Dissociation and stress were measured at two different times over three months. Since information campaigns and psychological support programs were offered to all participants, levels of stress were expected to decrease significantly. The data show that dissociative experiences are elevated when subjects experience high levels of current stress, though scores fall within the normal non-pathological range. Furthermore, it appears that a decrease in stress level is associated with a significant decrease of dissociative symptoms. The results support a one-directional causal relationship: a decrease in perceived stress leads to a decrease in dissociative phenomena.

Interapy: a controlled randomized trial of the standardized treatment of posttraumatic stress through the internet.

Online therapy offers many advantages over face-to-face therapy. Interapy includes psychoeducation, screening, effect measures, and a protocol-driven treatment via the Internet for people suffering from posttraumatic stress. The present article reports the results of a controlled trial on the Internet-driven treatment of posttraumatic stress and grief in a group of people who manifested mild to relatively severe trauma symptoms. Participants in the treatment condition (n=69) improved significantly more than participants in the waiting-list control condition (n=32) on trauma-related symptoms and general psychopathology. The effect sizes were large. On most subscales, more than 50% of the treated participants showed reliable change and clinically significant improvement, with the highest percentages being found for depression and avoidance.

Interapy: treatment of post-traumatic stress via the internet.

This paper describes the theoretical background and procedures (including psycho-education, screening, treatment protocol and outcome measurement) involved in a protocol-driven internet treatment of post-traumatic stress and grief in a group of people who have suffered from mild to relatively severe trauma. The paper examines the results of 3 outcome and process studies, which were carried out initially in a student population and subsequently in the general population of highly traumatized people. In the latter study, participants in the experimental condition (n = 69) improved significantly more than participants in the waiting list control condition (n = 32), with respect to trauma-related symptoms and general psychopathology. The effect sizes were large. More than 50% of the participants treated showed reliable change and clinically significant improvement after treatment for avoidance and depression. Treatment proved most beneficial for participants who had suffered from intentional trauma and those who had not previously discussed the traumatic events with significant others. Content analysis of the publications indicates a remarkable increase in cognitive coping during treatment. The possibilities for future research into internet-driven treatment of post-traumatic stress symptomatology are discussed, including the proposal to study the effects of sending a final written letter to a significant other person.

PACHIQ-R: the Parent-Child Interaction Questionnaire--revised.

The PACHIQ (Parent-Child Interaction Questionnaire) is designed to help clinicians and researchers assess how parents view relationship with their children (PACHIQ-Parent version), and how children evaluate their relationship with their parents (PACHIQ-Child version). The items in this questionnaire refer to both interpersonal behavior and feelings. Conceptually, the PACHIQ is based on learning theory and structural systems theory. The development of the PACHIQ was described by Lange, Blonk and Wiers (1998). The present article reports additional psychometric data obtained in the development and validation of a revised, shorter version of the questionnaire (PACHIQ-R). We present norm tables for families with children who are referred for psychological treatment, and norm tables for families in the normal Dutch population. The PACHIQ-R displays a two-factor structure with factors interpreted as Conflict Resolution and Acceptance. The parent version of the PACHIQ-R contains 21 items, the child version 25 items.

Structured writing and processing major stressful events: a controlled trial.

BACKGROUND: Traumatic events may result in a variety of physical and psychological health problems. Self-confrontation with traumatic memories, by putting painful emotions and thoughts into (verbal) words, is associated with psychophysiological benefits. Self-confrontation may be invoked during sessions and enhanced by structural assignments, which the client carries out between the sessions. In this context, writing assignments could be a useful tool in reprocessing traumatic events. The effects of writing assignments have been demonstrated in several case studies and in a number of experimental studies. However, the experimental studies have several limitations, for example the effects of writing on the impact of trauma are not examined. Furthermore, the psychological mechanisms that mediate the effects of trauma on health are less clear. These two issues are the main issues of the current study. METHODS: A group of 26 participants were instructed to write about their negative events during five 45-min sessions over a period of 2 weeks. They were compared at pre-treatment, post-treatment and at 6-week follow-up to a waiting-list control group (n = 22). RESULTS: The trauma-writing groups experienced fewer intrusions and showed less avoidance behavior from pre-treatment to follow-up, whereas the waiting-list control group did not change significantly. Similar results were found on depressive symptoms. No effects on mood measures were found. CONCLUSIONS: Implications for future research and clinical practice are discussed.
