The use of a coping strategy focused support group for carers of dementia sufferers

The paper describes the development and evaluation of coping strategy focused courses for informal carers of dementia sufferers (The Ways of Coping Course). Carers who attended the courses were interviewed before, immediately after and three months later, measuring their coping strategies, level of depression and strain, knowledge concerning dementia and satisfaction with the courses. They were compared to a second group of carers who attended educationally-focused courses consisting of a series of seminars on dementia. Both groups showed a signijicant increase in problem focused and decrease in distancing coping strategies but no change in levels of depression or strain. The carers in the Ways of Coping group showed an increase in acting out behaviour immediately following the courses and also showed greater levels of satisfaction with the courses overall.     

Understanding the impact of attachment insecurity on PTSD symptoms among male Veterans and military personnel

ABSTRACT

Attachment insecurity (i.e., attachment anxiety and attachment avoidance) has been found to contribute to PTSD symptom severity in Veterans. However, little is known of the unique contribution of attachment insecurity on individual PTSD symptom clusters. In a community sample of 106 combat-deployed Veterans, active duty service members, and reservists, this study examined: (1) the relationships between childhood family experience, combat experience, attachment insecurity, and PTSD symptom clusters, and (2) the influence of attachment insecurity on PTSD symptom clusters. Results revealed significant correlations between attachment anxiety and all PTSD symptom clusters (rs = .22 –.43) and attachment avoidance and PTSD symptom clusters, except the avoidance cluster (rs = .21 ?.36). Four multiple regression analyses were employed to address the second study aim. Childhood family experiences predicted negative alterations in cognitions and mood (β = –.30) and alterations in arousal and reactivity (β = –.20). Further, combat experience significantly predicted each symptom cluster of PTSD (βs = .03 –.44). In the second step, attachment anxiety and attachment avoidance were added to each model. Attachment anxiety and attachment avoidance predicted negative alterations in cognitions and mood (βs = .22 and .35) and alterations in arousal and reactivity (βs = .27 and .17). Inconsistent with previous research, attachment insecurity did not predict symptoms of avoidance. These results highlight the impact of attachment among a diverse sample of trauma exposed individuals and may provide insights for clinical implications and therapeutic approaches when working with Veterans and military personnel high in attachment insecurity.     

Subjective and physiological responses to the 35% carbon dioxide challenge in healthy and non-clinical control populations: a meta-analysis and systematic review

Background/Rationale: The carbon dioxide (CO₂) challenge has been reliably used in laboratory settings as a panicogen in clinical populations. However, the magnitude of these effects on healthy and non-clinical control populations are not clear. The aim of this meta-analysis and systematic review is to provide quantitative estimates of those effects. Specifically, the current paper will evaluate the relative efficacy of the CO₂ challenge in eliciting both subjective and physiological arousal in healthy and non-clinical control populations.

Method: A total of 16 articles with 35 independent samples were included in the meta-analysis, while 37 studies with 74 independent samples were included in the systematic review.

Results: Both the meta-analysis and systematic review found the CO₂ challenge to elicit an increase in subjective distress via self-reported anxiety and fear. Physiological responses via blood pressure and heart rate were heterogeneous in studies sampled, with no significant changes observed across studies. Moderator analyses revealed the variations in findings may be attributed to participant screening and invasive sampling.

Discussion: Findings highlight the CO₂ challenge as a useful tool in the provocation of subjective distress. Implications for both the use of the CO₂ challenge and its anticipated effects in healthy and non-clinical control populations are discussed.
