Food Waste in Schools: A Pre-/Post-test Study Design Examining the Impact of a Food Service Training Intervention to Reduce Food Waste.

This study aimed to assess change in school-based food waste after training and implementing the Smarter Lunchrooms Movement (SLM) strategies with school food service workers. This non-controlled trial was implemented in a random sample of 15 elementary and middle schools in a Community Eligibility Program school district in the Northeast, the United States. Baseline and post-intervention food waste measurements were collected at two different time points in each school (n = 9258 total trays measured). Descriptive statistics, independent t-tests, and regression analyses were used to assess SLM strategies' impact on changes in percent food waste. The mean number of strategies schools implemented consistently was 7.40 ± 6.97 SD, with a range of 0 to 28 consistent strategies. Independent t-tests revealed that at post-test, there was a significant (p < 0.001) percent reduction (7.0%) in total student food waste and for each food component: fruit (13.6%), vegetable (7.1%), and milk (4.3%). Overall, a training session on food waste and the SLM strategies with school-based food service workers reduced school food waste. However, the extent of the training and SLM strategies to reduce food waste varied on the basis of the consistency and type of strategies implemented.

Contingency Management with pharmacologic treatment for Stimulant Use Disorders: A review.

OBJECTIVES: Stimulant Use Disorders (SUDs) are an emergent public health concern in the United States and worldwide. However, there is still a lack of consensus for best-approaches regarding treatment of SUD. Recent trials have evaluated combinations of medications and psychosocial treatments to enhance efficacy. Contingency Management (CM) is a behavioral intervention that has shown effectiveness in treating SUDs. Our aim was to review studies using a combined methods approach such as CM and medications for the treatment of SUD. DESIGN: We performed a qualitative literature review of clinical trials that combined CM with any pharmacological treatment for SUDs. RESULTS: Among twenty-one publications included, ten reviewed a combination of CM and medications was superior to each intervention alone. In three of studies patients receiving CM showed better outcomes than those with no CM, regardless of their medication status. In one, groups receiving medication with or without CM had better outcomes than groups that received no medication. Finally, seven of the studies found no difference in the outcomes of interest for either CM, medication, or the combination of CM and medication. CONCLUSIONS: CM and medication as treatment for SUD could act synergistically and enhance each other's effect. Combining CM and medications may be a key strategy for effective SUD treatment. Future studies should further investigate the efficacy of the combined approach of medications and CM.

Translation and validation of the Brown attention-deficit disorder scale for use in Brazil: identifying cases of attention-deficit/hyperactivity disorder among samples of substance users and non-users. Cross-cultural validation study.

BACKGROUND: The Brown Attention-Deficit Disorder Scale (BADDS) was developed as a self-report assessment that was designed to screen for presence of symptoms of attention deficit hyperactivity disorder (ADHD). The objective here was to translate and validate the adult self-report BADDS for use in Brazil. DESIGN AND SETTING: Cross-cultural validation study conducted in an addiction unit at a public university hospital. METHODS: This study included a control group (n = 100) and a drug-user group (n = 100). Both groups included subjects aged 18 to 60 years old. The control group had no prior diagnosis of drug addiction and the drug-user group included participants with a diagnosis of addiction. Each participant answered Brazilian Portuguese translations of both the BADDS and the Adult Attention Deficit Hyperactivity Disorder Self-Report Scale (ASRS) questionnaires, in paper-and-pencil format. RESULTS: The drug-user group scored higher than the control group on both scales. The mean scores on ASRS were 27.26 (standard deviation, SD: 11.99) and 25.85 (SD: 8.65) respectively (P > 0.05). The mean scores on BADDS were 79.56 (SD: 29.61) and 79.31 (SD: 18.09), respectively (P > 0.05). Cronbach's alpha for BADDS was 0.95. BADDS presented fair sensitivity (72% accuracy) and fair specificity (88% accuracy). CONCLUSION: This study provides discriminative validity evidence for use of BADDS among Brazilian adults with substance-use disorders.
