Alcohol use and comorbid anxiety, traumatic stress, and hopelessness among Hispanics.

Little is known about the comorbidity of alcohol use, anxiety, hopelessness, and trauma among Mexican Americans, especially those living in impoverished and often isolated communities or neighborhoods (colonias in Spanish) along the U.S.-Mexico border that may be particularly vulnerable due to stressful living conditions. The current study utilized a community participatory model to investigate the relationships of alcohol use, acculturation, anxiety, hopelessness, and trauma in 100 Mexican origin colonia residents. Significant comorbidity was expected and that anxiety, hopelessness, and post-traumatic symptoms were hypothesized to be associated with the severity of the alcohol use disorders of participants. Participants who met DSM-IV criteria for alcohol dependence reported significantly more symptoms of anxiety and post-traumatic stress, and symptoms of anxiety were significantly associated with alcohol use disorders. This study provides evidence of the need for further investigation of stress, trauma, anxiety, hopelessness, and alcohol abuse in Mexican American residents and to inform future prevention and treatment efforts to improve both the physical and mental health of this population.

Motivation and neuropsychological test performance following mild head injury.

Effect of motivation on neuropsychological test performance in mild head injury was assessed. Motivation was measured using the Portland Digit RecognitionTest. Three groups were compared: (a) mildhead injury, financial incentives, good motivation; (b) mild head injury, financial incentives, poor motivation; (c) moderate/severe head injury, good motivation. The neuropsychological battery included measures of sensory function, motor function, attention, intelligence, abstract reasoning, and memory. Mild head injury well motivated patients performed significantly better than the other two groups on some tests. Mild head injury poorly motivated individuals and moderate-severe head injury patients were indistinguishable on many tests. Consistent with previous reports, tactile sensory (finger recognition and Fingertip Number Writing Perception) and recognition memory (Rey Auditory Verbal Learning) tasks were identified as clinically useful measures of poor motivation. On these measures mild head injury well motivated examinees performed no better than moderate-severe patients, with both groups superior to mild head injury poorly motivated examinees. Sensitivity and specificity data are reported. Our measures of tactile sensation and verbal recognition memory were more affected by motivation than by the severity of head injury.

Pain Assessment for the Dementing Elderly (PADE): reliability and validity of a new measure.

OBJECTIVES: To establish the reliability and validity of a measure to assess pain in individuals with advanced dementia. DESIGN: Sixty-five residents of long-term care facilities were assessed using a new rating tool, the Pain Assessment for the Dementing Elderly (PADE), in two separate studies: (1) Residents were assessed simultaneously by two different raters, at Time 1 and 2, to establish interrater reliability, stability, and internal consistency. (2) Validity was established by assessing the correlation between an agitation scale and the PADE; by comparing groups with pain as a significant clinical factor (as assessed by an independent rater) versus not a significant factor, and by assessing individuals receiving versus not receiving psychoactive medications. SETTING: Four different long-term care facilities, three skilled nursing facilities, and a locked dementia assisted-living facility. PARTICIPANTS: Twenty-five residents of long-term care facilities with advanced levels of dementia in Study 1, and 40 residents with similar level of dementia in Study 2; 42% of the total sample were rated as having significant painful conditions. MEASUREMENTS: For Study 1, the PADE was administered; for Study 2, the PADE and the Cohen-Mansfield Agitation Inventory (CMAI) were administered. RESULTS: Reliability coefficients were adequate (interrater = 0.54-0.95; stability = 0.70-0.98; and internal consistency = 0.24-0.88). Validity coefficients were likewise encouraging, with the PADE demonstrating the expected relationship with a measure of agitation. The PADE also differentiated between groups that were independently judged to suffer clinically problematic pain versus those who were not. CONCLUSION: The PADE is a reliable and valid tool to assess pain in dementing elderly residents of long-term care facilities.
