Communities Healing And Transforming Trauma (CHATT): A Trauma-Informed Speakers' Bureau for Survivors of Violence.

There is increasing recognition of the value of consumer participation in advocacy and community activism. Among trauma survivors, finding a sense of purpose and a way to make meaning from the trauma experience has been termed "survivor mission," and may include a call to social action, involvement in social justice activities, or public speaking. The current study describes the development of a trauma-informed trauma-survivor speakers' bureau (CHATT) and presents quantitative and qualitative outcome findings. The CHATT program encompasses (1) a speaker training component, (2) public speaking activities, and (3) speaking support groups. Trauma survivors (N = 27) who received trauma mental health (MH) services and were in the later stages of recovery completed the two-part seven-hour speaker training and subsequently presented talks at 13 venues to 192 audience members during a three-year study period. Speakers completed baseline measures prior to the training, and follow-up measures at six months and one year to assess posttraumatic growth (PTG) and self-efficacy. Audience members completed an assessment of change in beliefs about key speaker advocacy goals, as well as emotional reactions and satisfaction with talks. Results revealed PTG and speaking self-efficacy increased for speakers after one-year post-training. Audience ratings of talks averaged in the high range except for one domain. Ratings differed by audience type and number of speakers, and increased as the program matured. Key speaker advocacy successes including state policy changes, limitations, and implications for future research and development are discussed.

What do macroinvertebrate indices measure? Stressor-specific stream macroinvertebrate indices can be confounded by other stressors.

Monitoring programmes worldwide use biota to assess the "health" of water bodies. Indices based on biota are used to describe the change in status of sites over time, to identify progress against management targets and to diagnose the causes of biological degradation. A variety of numerical stressor-specific biotic indices have been developed based on the response of biota to differences in stressors among sites. Yet, it is not clear how variation in pressures within sites, over what time period, and in what combination has the greatest impact on different biotic groups. An understanding of how temporal variation in pressures influences biological assessment indices would assist in setting achievable targets and help focus catchment-scale mitigation strategies to ensure that they deliver the desired improvements in biological condition.Hydrochemical data provided by a network of high-frequency (15 or 30 min) automated monitoring stations over 3 years were matched to replicated biological data to understand the influence of spatio-temporal variation in pollution pressures on biological indices. Hydrochemical data were summarised in various ways to reflect central tendency, peaks, troughs and variation over 1-90 days before the collection of each biological sample. An objective model selection procedure was used to determine which hydrochemical determinand, and over what time period, best explained variation in the biological indices.Stressor-specific indices derived from macroinvertebrates which purportedly assess stress from low flows, excess fine sediment, nutrient enrichment, pesticides and organic pollution were significantly inter-correlated and reflected periods of low oxygen concentration, even though only one index (ASPTWHPT, average score per taxon) was designed for this purpose. Changes in community composition resulting from one stressor frequently lead to confounding effects on stressor-specific indices.Variation in ASPTWHPT was best described by dissolved oxygen calculated as Q5 over 10 days, suggesting that low oxygen events had most influence over this period. Longer-term effects were apparent, but were masked by recovery. Macroinvertebrate abundance was best described by Q95 of stream velocity over 60 days, suggesting a slower recovery in numbers than in the community trait reflected by ASPTWHPT.Although use of ASPTWHPT was supported, we recommend that additional independent evidence should be used to corroborate any conclusions regarding the causes of degradation drawn from the other stressor-specific indices. The use of such stressor-specific indices alone risks the mistargeting of management strategies if the putative stressor-index approach is taken to be more reliable than the results herein suggest.
