- Background: Apathy, a prevalent and clinically relevant symptom in neurodegenerative disease, is often evaluated by the instrument Apathy Evaluation Scale (AES). However, this instrument has not been translated into Swedish, halting clinical and research efforts. Furthermore, previous studies lack analyses of some basic properties, such as the legitimacy of a total score, or have analysed dimensionality by questionable methods.Aim: To translate and psychometrically evaluate a Swedish version of the AES.Method: The AES was translated, and its psychometric properties were tested in the Swedish BioFINDER study, including cognitively well elderly, and subjects with mild cognitive or parkinsonian symptoms. Psychometric analyses were conducted according to classical test theory (CTT) and aimed to resemble those performed in the English original study by Marin etal. in 1991. Dimensionality was additionally analysed on a matrix of polychoric correlations and parallel analyses.Results: Data indicate that the Swedish AES performs satisfactorily regarding data completeness, scaling assumptions, targeting, and reliability. Principal component analyses (with parallel analysis) of polychoric correlation matrices identified a single component. Convergent and discriminative validity correlations accorded with a priori expectations.Conclusions: The study provides initial support that this Swedish AES performs similarly to the English original, and exhibits acceptable psychometric properties according to CTT, including supported unidimensionality, and may be adopted for use in clinical and research settings.

- AIMS: To describe persons visiting the psychiatric emergency room (PER) in Sweden and to compare persons who frequently (PFV) and infrequently (PIFV) visit PERs in terms of group size, age, gender, PER location inside versus outside the home municipality, diagnosis (ICD 10), temporal patterns of visits and hospital admissions.METHODS: This register study included all visits to PERs in one Swedish county over 3 years, 2013-2015 (N = 67,031 visits). The study employed descriptive statistics as well as Chi-square tests combined with Bonferroni correction to compare PFV with PIFV.RESULTS: Of the total of 27,282 visitors, 2201 (8.1%) were identified as PFV (five or more visits within 12 months) and they accounted for 38.1% of the total visits. The study found differences between PFV and PIFV in gender, diagnostic profile, hospital admissions and temporal patterns. Differences were also detected with regard to distance between PERs and home municipalities. However, no age-related differences were found between the two groups.CONCLUSIONS: PFV and PIFV have different clinical profiles and temporal patterns. These results may be important when planning, developing and evaluating interventions targeting the needs of each group, which is in accordance with a person-centred approach. Such an approach might eventually result in fewer visits to PERs.
