Background: In ageing populations fear of falling is an important issue. International studies and collaborations require scales suitable to more cultures. Scales developed in one culture require adaptation and additional investigation of psychometric properties for use in other countries.OBJECTIVE: To investigate the psychometric properties of a Dutch version of the Activities-specific Balance Confidence scale (ABC-NL) and whether adding questions about complex/dual tasks improves the discriminatory power.METHOD: Subjects were 106 men and 140 women aged 65-92 years. Measures were the 16-item ABC-NL and seven additional more complex items, fall history, general and physical self-efficacy, a functional reach test and a balance platform test.RESULTS: The ABC-NL had a weak ceiling effect. Internal consistency (Cronbachs alpha) was high. The relationship between ABC-NL and physical self-efficacy was significantly stronger than between the ABC-NL and general self-efficacy. Relationships with performance-based measures of balance were moderate. Differences between fallers and non-fallers and between activity avoiders and non-avoiders were significant. Adding questions about complex tasks hardly improved discriminatory power, reliability and validity.CONCLUSION: Psychometric properties of the ABC-NL were satisfactory. Further research is needed for use in high-functioning older persons. Language: nl

The imagination of motor actions forms not only a theoretical challenge for cognitive neuroscience but may also be seen as a novel therapeutic tool in neurological rehabilitation, in that it can be used for relearning motor control after damage to the motor system. However, since the majority of rehabilitation patients consist of older individuals it is relevant to know whether the capacity of mental imaging is compromised by age. Scores on the vividness of movement imagery questionnaire were obtained for 333 participants, divided in three age groups. Results showed that elderly participants were slightly worse in motor imagery capacity than younger participants, particularly in relation to motor imagery from an internal (first person) perspective. Furthermore, a possible relation between the level of physical activities and motor imagery capacity is discussed. (C) 2007 Elsevier B.V. All rights reserved.

Background: Interventions to promote successful aging include psychological and physical activity programs. Identification of determinants of attendance of older persons may be useful to develop strategies to improve attendance. For physical activity programs determinants of attendance have been investigated extensively. For psychological programs hardly any knowledge is available. Determinants of attendance at psychological and physical activity programs have never been investigated simultaneously. Objective: To identify demographic, physical and psychological determinants of attendance of older subjects following multifaceted psychological training – aimed at promoting active social participation – and physical activity training and to compare the variation of these determinants between the two training programs. Method: 118 subjects aged 65–92 years were randomized over psychological and physical activity training. Determinants of attendance were obtained at pretest with questionnaires and performance-based tests. Results: Mean attendance was 62%. Attendance was not related to type of program. Having chronic diseases facilitated attendance in the psychological training group and limited attendance in the physical activity training group. Low and high levels of Activities of Daily Living performance (ADLs) and walking endurance were related to a high attendance in the psychological training group. A low level of activities of daily living (ADL) and a low walking endurance were related to a low attendance in the physical activity training group. For both training groups, persons living with a partner had higher attendance rates than persons living alone, and persons with a low level of anxiety had higher attendance rates than persons with a moderate or a high level of anxiety. Conclusion: Psychological training may be more suitable for frail older persons with chronic diseases, low ADL levels and low walking endurance than physical activity training, and may help to prepare such persons for physical activity.
