Mental disorders among parents/caretakers of American Indian early adolescents in the Northern Midwest.

BACKGROUND: This study reports prevalence and comorbidity of five DSM-III-R diagnoses (alcohol abuse, alcohol dependence, drug abuse, major depressive episode, and generalized anxiety disorder) among American Indian and Canadian First Nations parents/caretakers of children aged 10-12 years from the Northern Midwest United States and Canada. Lifetime prevalence rates were compared to adults in the National Comorbidity Survey (NCS) and Southwest and Northern Plains cultures from the AI-SUPERPFP study. METHOD: Native interviewers used computer-assisted personal interviews to administer the University of Michigan Composite International Diagnostic Interview (UM-CIDI) to 861 tribally enrolled parents and caretakers (625 females; 236 males) of 741 tribally enrolled children aged 10-12 years. Fathers/male caretakers ranged in age from 21 years to 68 years with an average age of 41 years; mothers/female caretakers ranged in age from 17 years to 77 years with an average of 39 years. RESULTS: About three-fourths (74.6%) of the adults met lifetime criteria for one of the five disorders; approximately one-third (31.6%) met lifetime criteria for two or more of the five disorders. Prevalence of the substance use disorders was higher than those in the general population (NCS); prevalence of internalizing disorders (major depressive disorder and generalized anxiety disorder) was very similar to those in the general population. Prevalence rates for alcohol abuse among the Northern Midwest adults were higher than those reported for Southwest and Northern Plains Tribes, but rates of alcohol dependency were very similar across cultures. CONCLUSIONS: The higher prevalence rates for some mental disorders found for the Northern Midwest are discussed in terms of potential method variance. The Northern Midwest results reflect unique patterns of psychiatric disorders in the ubiquity of substance abuse disorders and the co-occurrence of substance abuse disorders with internalizing disorders. Reducing lifetime occurrences of substance abuse disorders would have an enormous positive impact on the mental health of this population.

Traditional practices, traditional spirituality, and alcohol cessation among American Indians.

OBJECTIVE: The detrimental effects of alcohol misuse and dependence are well documented as an important public-health issue among American Indian adults. This preponderance of problem-centered research, however, has eclipsed some important resilience factors associated with life course patterns of American Indian alcohol use. In this study, we investigate the influence of enculturation, and each of the three component dimensions (traditional practices, traditional spirituality, and cultural identity) to provide a stringent evaluation of the specific mechanisms through which traditional culture affects alcohol cessation among American Indians. METHOD: These data were collected as part of a 3-year lagged sequential study currently underway on four American Indian reservations in the upper Midwest and five Canadian First Nation reserves. The sample consisted of 980 Native American adults, with 71% women and 29% men who are parents or guardians of youth ages 10-12 years old. Logistic regression was used to assess the unique contribution of the indicators of alcohol cessation. Excluding adults who had no lifetime alcohol use, the total sample size for present analysis is 732 adult respondents. RESULTS: The findings show that older adults, women, and married adults were more likely to have quit using alcohol. When we examined the individual components of enculturation, two of the three components (participation in traditional activities and traditional spirituality) had significantly positive effects on alcohol cessation. CONCLUSIONS: Although our findings provide empirical evidence that traditional practices and traditional spirituality play an important role in alcohol cessation, the data are cross-sectional and therefore do not indicate direction of effects. Longitudinal studies are warranted, in light of the work that concludes that cultural/spiritual issues may be more important in maintaining sobriety once it is established rather than initiating it.

Getting the work done: a qualitative study of individuals with multiple sclerosis.

THE PROBLEM: Work can be defined as an activity performed to accomplish something in the presence of obstacles that may make accomplishing the goal difficult. For individuals with MS, work is not only limited by physical impairments but also by factors such as fatigue and cognitive changes PURPOSE: The aim of this study is to examine the experiences of individuals with mild to moderate MS as they carry out everyday work activities both inside and outside the home. METHOD: Eleven women and three men were recruited from the community to participate in a series of semi-structured interviews. Using qualitative research methodology that examined the experiences of the participants, two major themes and seven subthemes emerged. RESULTS: The first theme, Defining the work, included Priorities: seeing what's important; Plans: learning about resources and requirements; and PERSPECTIVES: fixing it yourself. The second theme, Changing how things get done, includes Precipitating factors; Awareness; Constructing the strategies; and Evaluating the strategies. CONCLUSIONS: Individuals with MS develop strategies and utilize resources in order to get the work done. Comparisons are made between existing intervention theories or programmes and the experiences described by participants in this study.

The use of a World Wide Web-based consultation site to provide support to telephone staff in a traumatic brain injury demonstration project.

OBJECTIVES: Distance from expertise in traumatic brain injury (TBI) is often an impediment to appropriate TBI care from local health care providers, especially in rural areas. To overcome this barrier to care and to support a randomized, controlled trial of telephone follow-up after discharge from acute rehabilitation, we demonstrated the use of a confidential consultation Web site to provide expert recommendations and advice to front-line telephone staff at a different site. CONCLUSIONS: This use of Internet communication proved convenient to all users, improved client confidence, and served as an excellent training tool to less experienced staff. In addition, use of a Web-based consultation method provided for archiving of all discussions for later review.

Performance Tested Method multiple laboratory validation study of ELISA-based assays for the detection of peanuts in food.

Performance Tested Method multiple laboratory validations for the detection of peanut protein in 4 different food matrixes were conducted under the auspices of the AOAC Research Institute. In this blind study, 3 commercially available ELISA test kits were validated: Neogen Veratox for Peanut, R-Biopharm RIDASCREEN FAST Peanut, and Tepnel BioKits for Peanut Assay. The food matrixes used were breakfast cereal, cookies, ice cream, and milk chocolate spiked at 0 and 5 ppm peanut. Analyses of the samples were conducted by laboratories representing industry and international and U.S governmental agencies. All 3 commercial test kits successfully identified spiked and peanut-free samples. The validation study required 60 analyses on test samples at the target level 5 microg peanut/g food and 60 analyses at a peanut-free level, which was designed to ensure that the lower 95% confidence limit for the sensitivity and specificity would not be <90%. The probability that a test sample contains an allergen given a prevalence rate of 5% and a positive test result using a single test kit analysis with 95% sensitivity and 95% specificity, which was demonstrated for these test kits, would be 50%. When 2 test kits are run simultaneously on all samples, the probability becomes 95%. It is therefore recommended that all field samples be analyzed with at least 2 of the validated kits.
