Reliability and internal consistency of the Swedish version of the MAastrIcht Nurses Activities INventory (MAINtAIN(S)) - A pilot testing of the tool.

Objectives: To evaluate the test-retest reliability and internal consistency of the Swedish version of the MAastrIcht Nurses Activities INventory (MAINtAIN(S)) developed to measure nursing staff perceived behaviours and barriers for promotion of everyday activities in nursing home residents.

Method: Nursing staff completed the MAINtAIN(S) questionnaire on two occasions at 3-week intervals. Relative reliability, absolute reliability and internal consistency with Cronbach's alpha were calculated.

Results: The test--retest reliability of MAINtAIN(S)-behaviours subscales ranged from ICC = 0.78--0.91 and MAINtAIN(S)-barriers subscales from ICC = 0.60--0.84. Cronbach's alpha varied between 0.60 and 0.91 for the different subscales. The MAINtAIN(S) inventory shows acceptable reliability and internal consistency. MAINtAIN(S) seems to be a promising tool for identifying behaviours and barriers in promoting everyday activities in nursing home residents and can be used to develop ward specific interventions for promotion of daily physical activity level in the care of older adults.
