1. The persons with dementia include age, gender, education level, marital status, degree of dementia, period of illness, Mini-Mental State Examination (MMSE), etc. The family caregivers include age, gender, education level, marital status, etc.
2. This scale is used to evaluate family caregivers.

1. Dementia's behavioral problems were measured by the Chinese version of the CMAI, community form (Cohen-Mansfield, J et al. 1989, 1991, C.K.Y. Lai, pers. comm.).
2. The 43-item CMAI has four subscales that assess four groups of behavioral problems: physically non-aggressive behavior, physically aggressive behavior, verbally aggressive behavior and verbally non-aggressive behavior. Each item's score ranges from 1 (never happened) to 7 (several times in an hour). Scores can range from 43-301, with higher scores representing more frequent or more types of behavioral problems.
3. This scale is used to evaluate family caregivers.

1. Family caregivers' self-efficacy for caring agitated behavior of older people with dementia was measured by the Agitation Management Self-Efficacy Scale (AMSS), which was developed by our research team. (Huang, Shyu, Chen, & Hsu, 2009)
2. For each of the 43 behavioral problems identified by the Chinese version of the CMAI, caregivers are asked how confident they feel about handling the problem. Each AMSS item is scored on a Likert-type scale from 1 (not able to handle at all) to 5 (totally able to handle). Total scores range from 43-215. Higher scores represent greater caregiver self-efficacy to handle behavioral problems.
3. This scale is used to evaluate family caregivers.

2. The ADL refers to activities oriented toward taking care of one's own body.
3. This scale assesses 10 items related to the activity including feeding, transfer, grooming, toilet use, bathing, mobility, stairs, dressing, bowels, and bladder. Each item is scored from 0 (maximum disability and dependency) to 20 (maximum strength and independence). Scores can range from 0 to 100, with higher scores representing more independence.

2. The IADL refers to activities oriented toward interacting with the environment and that are often complex-generally optional in nature.
3. This scale assesses 8 items related to the activity including the ability to use a phone, shopping, the model of transportation, meal preparation, housekeeping, laundry, the responsibility for owns medication, and the ability to handle finance. Each item is scored from 0 (dependency) to 3 (independence). Scores can range from 0 to 24, with higher scores representing more independence.
4. This scale is used to evaluate family caregivers.

1. This scale was developed by our research team by referring to The measure of caregiver competence developed by Kosberg and Cairl. (Kosberg & Cairl, 1991; Huang & Shyu, 2003)
2. This scale is used to assess the caregiver's ability to perform care tasks.
3. Each item is scored from 1 to 5. Scores can range from 20 to 100, with higher scores representing the ability better.
4. This scale is used to evaluate family caregivers.

1. This scale was developed by our research team by referring to The Preparedness for Caregiving Scale (PCS) developed by Archbold et al. This scale is to rate how well prepared they believe they are for caregiving (Archbold et al.,1990; Huang, Kuo, et al., 2013).
2. This 11-items scale was scored on a 5-point Likert scale from 1 (unprepared) to 5 (well prepared). Scores range from 11 to 55, with higher scores representing greater preparedness for caregiving tasks. A final question is an open-end question.
