Subthreshold depression in older subjects: an unmet therapeutic need.

Major depression, defined according to DSM IV TR criteria, is less common in older subjects, while other types of depression are two to three times more prevalent. This heterogeneous group of disturbances has received different names: depression not otherwise specified, minor depression, subthreshold or subsyndromal depression. Moreover, each condition has been defined using heterogeneous criteria by different authors. The term of subthreshold depression will be adopted in this position statement. Subthreshold depression has been associated with the same negative consequences of major depression, including reduced well being and quality of life, worsening health status, greater disability, increased morbidity and mortality. Nevertheless, there is a dearth of clinical trials in this area, and therefore older patients with subthreshold depression are either not treated or they are treated with the same non pharmacological and pharmacological therapies used for major depression, despite the lack of supporting scientific evidence. There is an urgent need to reach a consensus concerning the diagnostic criteria for subthreshold depression as well as to perform clinical trials to identify effective and safe therapies in this too long neglected patient group.

Validation of the Italian version of the falls efficacy scale international (FES-I) and the short FES-I in community-dwelling older persons.

Fear of falling (FF) is a common problem in older persons. FF negatively affects the quality of life by generating anxiety, loss of confidence and of self-efficacy, and, ultimately, activity restriction and increased risk of falling. The FES-I and Short FES-I are two instruments developed to assess FF in older persons which have been already validated in some European countries. Our objectives are to develop the Italian version of FES-I and the Short FES-I and to validate them in older persons. The back translation protocol adopted by the ProFaNE group was used to translate both scales from English to Italian. Participants were 157 community-dwelling persons aged>65 years who underwent comprehensive geriatric assessment, including a structured interview concerning FF, and were administered the FES-I and the Short FES-I. Both scales were re-tested after 4 weeks in 151 persons. FES-I and Short FES-I had high internal validity and test-retest reliability. The Short FES-I is highly comparable with the FES-I. We conclude that the FES-I and the Short FES-I are excellent instruments to asses FF in Italian older subjects and they may be used in future research projects and clinical trials.
