Cumulative trauma and perceived community resilience: A serial mediation model.

Communities affected by cumulative trauma can experience negative psychological reactions but also posttraumatic growth and community resilience, which promote adaptation and preparation for future traumatic events. This study aims to investigate the mechanisms that mediate the relationship between traumatic events and perceived community resilience. Participants were 118 Italian adults who experienced cumulative trauma and were recruited to complete an online survey. A serial multiple mediation model was estimated to assess whether the impact of the Morandi bridge collapse and posttraumatic growth mediated the relationship between the psychological impact of the Covid-19 pandemic and perceived community resilience. The impact of the collapsed bridge and posttraumatic growth in serial partially mediated the relationship between the impact of the Covid-19 pandemic and perceived community resilience. The impact of cumulative trauma can be considered through an ecological perspective that considers the consequences of these events in relation to community resilience.

Studying Nonlinear Change in Music Therapy Applying Dynamic Systems Theory.

Change in music therapy is often modeled linearly. In linear analysis, change is represented as the difference between the scores recorded before and after treatment, where changes in the input are proportional to the output. However, changes in complex systems are often not linear and depend on time. We propose Dynamic Systems Theory (DST) as a means to overcome the shortcomings of linear analysis and enrich the study of change in music therapy. This article aims to introduce and critically discuss the applications of DST in music therapy, focusing on its theoretical and methodological aspects. DST offers a meta-framework to model nonlinear change in music therapy, considering time as continuous. The application of DST can further enhance the understanding of how music therapy works, the shape of the change, and how the relevant therapeutic processes within music therapy support therapeutic change. An introduction to DST theory is provided along with its history, implications, assessment methods, statistical analyses, mathematical modeling, and implementation examples in music therapy research.

Premature Triadic Music Therapy (PT-MT) for babies and their parents: a pilot study.

OBJECTIVE: We aim to test the feasibility and effectiveness of Premature Triadic Music Therapy (PT-MT) in the premature baby unit. METHODS: The design was a clinical pre-test-post-test trial with a convenience sample. Inclusion criteria were a gestational age higher than 28 weeks for preterm infants and the absence of shock or extreme distress for parents. Six preterm children (with a gestational age of 33 to 36 weeks) and their parents participated in the study. For the children, we measured heart rate, blood perfusion, and blood saturation at three different times (pre-PT-MT, during PT-MT, after PT-MT) as quantitative indicators of distress. Their parents completed the Edinburgh Postnatal Depression Scale (EPDS) before and after the PT-MT intervention. RESULTS: We found a statistically significant lower heart rate and a marginally statistically significant higher blood perfusion during PT-MT, as compared to the baseline. However, these changes were not present at the end of PT-MT. The parents' EPDS scores were not statistically significantly lower at the post-test, although, the Medians of the scores did decrease. CONCLUSIONS: PT-MT is a promising intervention for the reduction of distress in both parents and children. Further studies should include a higher number of sessions and participants.
