Natural disasters are common and devastating, and can affect the mental health of adolescents. It is also common for adolescents to have histories of interpersonal violence (IPV). The current study was a secondary data analysis of a larger randomized clinical trial and examined the moderating effect of IPV history and concern for loved ones during a disaster on treatment condition effects on posttraumatic stress disorder (PTSD) symptoms over time among disaster-exposed adolescents. Participants (n = 979) were recruited postdisaster to participate in a randomized clinical trial examining the efficacy of a web-based intervention, Bounce Back Now (BBN), on mental health symptoms at 4 and 12 months postintervention. It was found that adolescents with an IPV history and who had caregivers that were concerned for loved ones during a disaster had more PTSD symptoms at baseline than those without such histories. Furthermore, caregiver concern for loved ones during a disaster moderated the effect of BBN on PTSD symptoms over time. Specifically, the BBN condition was most effective for adolescents who had caregivers who were concerned for loved ones during the disaster in reductions of PTSD symptoms over time. The current study provides further evidence for the use of technology-based interventions for individuals as a means to address mental health symptoms after a traumatic event, especially among those with more severe traumatic experiences.

The purpose of the current report was to examine prior history of exposure to interpersonal violence (IPV), as compared with prior accident or prior disaster exposure, experiences during and after a disaster, and demographic variables as predictors of past month posttraumatic stress disorder (PTSD) and depression severity among adolescents exposed to the tornadoes in Alabama and Missouri. IPV exposure has been consistently identified as a unique category of potentially traumatic events (PTE) that significantly increases risk for development of PTSD and other difficulties relative to other event types among adolescents. A population-based sample of adolescents and caregivers (N = 2,000) were recruited randomly from tornado-affected communities in Alabama and Joplin, Missouri. Participants completed structured telephone interviews on an average of 8.8 months posttornado. Prior history of IPV was prevalent (36.5%), as was reported history of accidents (25.9%) and prior disaster exposure (26.9%). Negative binomial regression analyses with PTSD and depression symptom counts for past month as outcome variables indicated that history of predisaster IPV was most robustly related to PTSD and depression symptoms, such that those with a history of IPV endorsed over 3 times the number of symptoms than those without IPV history. Final model statistics indicated that female gender, physical injury to caregiver, concern about others' safety, prior disaster, prior accident, and prior IPV exposure were also related to PTSD. Predictors of depression symptoms were similar with the exception that concern about others' safety was not a predictor and age was a predictor in the final model. It is important to evaluate potential additive effects of IPV history in addition to recent disaster exposure variables and to consider such history when developing interventions aimed to reduce or prevent symptoms of PTSD and depression among adolescents recently exposed to disaster.

Relatively few herbicides are registered in Alabama or in the southeastern United States for use in annual hill plasticulture production of strawberries. Acquisition of 24(c) special local needs status for certain herbicides could make more of these chemistries available to the strawberry industry. These herbicides, especially when applied as tank mixes pose potential risks to strawberry plant growth and fruit yield. Special local needs status for these herbicides has been granted for other states, but more evaluation of these products in Alabama soils under plastic mulch is needed. The objective of this study was to assess tank mix applications of preemergence herbicides with different modes of action on plant growth, crop yield, and fruit size of 'Camarosa' strawberry. A study was conducted at the Chilton Research and Extension Center in Clanton, AL, in 2018 and 2019. Pendimethalin (3.5 L·ha-1) and S-metolachlor (1.6 L·ha-1) were evaluated for potential phytotoxicity in 'Camarosa' strawberry when applied alone or in tank mixes with napropamide (8.6 kg·ha-1), sulfentrazone (0.3 L·ha-1), or terbacil (0.42 L·ha-1) by comparing them to a nontreated control. At 18 weeks after planting, pendimethalin tank mixed with napropamide reduced plant dry weight by 33% compared with the control, but this reduction was not significant. Additionally, tank mixes of pendimethalin with sulfentrazone, napropamide, and terbacil reduced shoot dry weight by 43%, 52%, and 43%, respectively, compared with pendimethalin alone. Pendimethalin + napropamide tank mix reduced relative growth rate by 95% compared with the control between 6 and 18 weeks after planting. All treatments were similar to the control in marketable yield. Differences in plant growth parameters did not appear to affect yield by the end of the experiment. All single applied treatments along with S-metolachlor tank mixed with napropamide and sulfentrazone; pendimethalin tank mixed with sulfentrazone and terbacil appeared to be safe for direct application to strawberry planting beds covered in polyethylene mulch.

Objective: The current study examined variables, including prior traumatic events, disaster exposure, and current mental health symptomatology, associated with suicidal ideation following experience of a natural disaster., Method: Utilizing a sample of 2,000 adolescents exposed to the spring 2011 tornadoes in the areas surrounding Tuscaloosa, Alabama, and Joplin, Missouri, we hypothesized that prior interpersonal violence (IPV), more so than other prior traumatic events or other symptoms, would be associated with suicidal ideation after the disaster., Results: Suicidal ideation was reported by approximately 5% of the sample. Results of binary logistic regression were consistent with hypotheses in that prior IPV exposure emerged as the variable most robustly related to presence of postdisaster suicidal ideation, even accounting for current symptoms (i.e., posttraumatic stress disorder and depression). Moreover, neither prior accident nor prior natural disaster exposure was significantly associated with postdisaster suicidal ideation, suggesting that something specific to IPV may be conferring risk for suicidality. No other variables, including disaster exposure variables or demographic characteristics, emerged as significantly related., Conclusions: Our results suggest that individuals who have a history of IPV may be particularly vulnerable following experience of additional traumatic events and that for suicide risk, the experience of prior IPV may be more relevant to consider in the aftermath of natural disasters beyond variables related to the index trauma or current symptomatology.
