Perceptions of the personal importance of exercise to respondents were measured with a validated 9-item Exercise Identity Scale[ 36].
The 5-item Exercise Self-Efficacy Scale (6) measures self-confidence to persist with exercise in various situations (14).
Therefore, the lymphedema-specific items were designed to be used as a subscale for a previously validated nine-item exercise barriers self-efficacy scale assessing general barriers (internal consistency, Cronbach's alpha = 0.95; test-retest reliability, r = 0.89, p < 0.001) [ 17], which was also included in the survey.
For two items (exercise tolerance and occupation) measured in relation to history taking, there was significant evidence of an improvement in hospitals over time.
The Self- Care Inventory- Revised (SCI- R) [ 12, 13] is a 15-item self-report questionnaire assessing patients' perceptions of various self-care behaviours, i.e. diet (4 items), glucose monitoring (2 items), medication administration (3 items), exercise (1 item), low glucose levels (2 items), preventative/routine aspects of care (3 items).
39 40 Questions for general diet (two items), specific diet (two items), exercise (two items), blood glucose testing (two items) and foot care (two items) use an eight-point Likert scale (from 0 to 7) to record the number of days in the past week that the activity was undertaken.
The FPI consists of 65 items and has six subscales: body care (9 items), household maintenance (21 items), physical exercise (7 items), recreation (11 items), spiritual activities (5 items), and social activities (12 items).
The second round results will also be submitted to an accepted workshop at the Low Back Forum, Brazil 2014 (http://www.lbpforum.com.br) for consensus among low back pain experts regarding item use in exercise programmes for low back pain.
Confirmatory factor analysis (CFA) was performed using AMOS 22.0 [ 26] to assess the model fit defined by the four factors diet (items 1 4), exercise (items 5 and 6), blood glucose testing (items 7 and 8) and foot care (items 9 and 10) using the maximum likelihood method.
Activity behavior included three items: exercising, participating in outdoor activities and doing household duties.
Especially, among five items, exercise-induced dyspnea, recurrent attacks of wheezing, and pollution induced dyspnea are more useful to differentiate asthmatics from non-asthmatics.
