A Cross-National Analysis of the Psychometric Properties of the Geriatric Anxiety Inventory.

OBJECTIVES: Assessing late-life anxiety using an instrument with sound psychometric properties including cross-cultural invariance is essential for cross-national aging research and clinical assessment. To date, no cross-national research studies have examined the psychometric properties of the frequently used Geriatric Anxiety Inventory (GAI) in depth. METHOD: Using data from 3,731 older adults from 10 national samples (Australia, Brazil, Canada, The Netherlands, Norway, Portugal, Spain, Singapore, Thailand, and United States), this study used bifactor modeling to analyze the dimensionality of the GAI. We evaluated the "fitness" of individual items based on the explained common variance for each item across all nations. In addition, a multigroup confirmatory factor analysis was applied, testing for measurement invariance across the samples. RESULTS: Across samples, the presence of a strong G factor provides support that a general factor is of primary importance, rather than subfactors. That is, the data support a primarily unidimensional representation of the GAI, still acknowledging the presence of multidimensional factors. A GAI score in one of the countries would be directly comparable to a GAI score in any of the other countries tested, perhaps with the exception of Singapore. DISCUSSION: Although several items demonstrated relatively weak common variance with the general factor, the unidimensional structure remained strong even with these items retained. Thus, it is recommended that the GAI be administered using all items.

Anxiety among older psychiatric patients: a hidden comorbidity?

OBJECTIVES: Our aims were to explore prevalence of anxiety among patients admitted to departments of geriatric psychiatry for treatment of various diagnoses and to examine how often anxiety was registered as a previous or ongoing diagnosis. METHOD: In all, 473 patients admitted to one of five departments of geriatric psychiatry were included in a quality register and examined according to a standardized protocol. The Geriatric Anxiety Inventory (GAI) was used to measure anxiety during the first week after admission. Diagnoses were made at discharge. RESULTS: Using a cutoff on the GAI of 8/9, the prevalence of anxiety for the following diagnostic groups was depression 65.3%, psychosis 28%, dementia 38.8% and mania 33.3%. Of 24 patients with a primary diagnosis of anxiety, 66.7% scored above 8 on the GAI. Of 236 patients with a GAI score above 8, only 22 (9.3%) were reported to have a comorbid anxiety disorder by the treating psychiatrist. In a multiple regression analysis, we found that the severity of depression (beta 0.585, p < 0.001), being female (beta 0.096, p 0.028) and the use of antipsychotic drugs (beta 0.129, p 0.006) and anxiolytic drugs (beta 0.129, p 0.005) were associated with a higher GAI score. CONCLUSION: Anxiety is common in geriatric psychiatric patients, regardless of the primary diagnosis. Our findings suggest that anxiety is often a hidden comorbidity in various psychiatric disorders. A high score on the GAI was associated with the severity of depression, female gender and the use of antipsychotic and anxiolytic drugs.

Deaths from violent causes and accidents in Hordaland County 2003-04.

BACKGROUND: Studies of the epidemiology of deaths from violent causes can provide valuable information for the treatment of traumas. We wished to ascertain whether the victims had survivable injuries and were accessible for treatment at the time of discovery of the injury. The purpose was to identify areas of intervention that may help save lives. MATERIAL AND METHOD: An overview of deaths from violent causes in Hordaland County in 2003 and 2004 was retrieved from the Cause of Death Registry, and information from autopsy records, hospital records and police reports was reviewed. In each case, an assessment was made of whether the injuries were survivable. If the patient was alive and could be reached and treated at the time when the incident was reported, he/she was defined as accessible for treatment. RESULTS: Altogether 191 deaths were included. We assessed the injuries as survivable in 26 cases. A total of 18 of these 26 patients were also assessed as accessible for treatment. All of these 18 patients died from falls or traffic accidents. 11 of the 18 patients were in the age group 75 years or older; this age group accounted for 41 cases (21.5%) of the total material. The records showed that in 12 of these 18 cases, it had been decided following an overall assessment not to initiate, or to discontinue, further life-saving treatment. INTERPRETATION: A small number of patients were deemed to have sustained survivable injuries while also being accessible for treatment. The results indicate that primarily efforts to prevent injuries will help reduce the number of deaths from violent causes.

Fatal injury as a function of rurality-a tale of two Norwegian counties.

BACKGROUND: Many studies indicate rural location as a separate risk for dying from injuries. For decades, Finnmark, the northernmost and most rural county in Norway, has topped the injury mortality statistics in Norway. The present study is an exploration of the impact of rurality, using a point-by-point comparison to another Norwegian county. METHODS: We identified all fatalities following injury occurring in Finnmark between 2000 and 2004, and in Hordaland, a mixed rural/urban county in western Norway between 2003 and 2004 using data from the Norwegian Cause of Death Registry. Intoxications and low-energy trauma in patients aged over 64 years were excluded. To assess the effect of a rural locale, Hordaland was divided into a rural and an urban group for comparison. In addition, data from Statistics Norway were analysed. RESULTS: Finnmark reported 207 deaths and Hordaland 217 deaths. Finnmark had an injury death rate of 33.1 per 100,000 inhabitants. Urban Hordaland had 18.8 deaths per 100,000 and rural Hordaland 23.7 deaths per 100,000. In Finnmark, more victims were male and were younger than in the other areas. Finnmark and rural Hordaland both had more fatal traffic accidents than urban Hordaland, but fewer non-fatal traffic accidents. CONCLUSIONS: This study illustrates the disadvantages of the most rural trauma victims and suggests an urban-rural continuum. Rural victims seem to be younger, die mainly at the site of injury, and from road traffic accident injuries. In addition to injury prevention, the extent and possible impact of lay people's first aid response should be explored.
