After informed consent has been obtained, patients and caregivers will be randomized to one of the two study groups: the intervention group (HABC 2.0 plus ABC Clinical program) or the comparison group (ABC Clinical Program-only). Randomization will be by dyad using a random number generator with unequal randomization using a 3:2 ratio to achieve n=132 and n=92 in the two arms (the larger enrollment in the intervention group), as recommended when expecting unequal drop-out. Within two weeks of enrollment, patients and their informal caregivers will complete a baseline assessment [including the Neuropsychiatric Inventory (NPI), the NPI-Caregiver Stress, the Patient Health Questionnaire-9 (PHQ-9), the Zarit Burden Interview and the Revised Scale for Caregiving Self-Efficacy] conducted by professional interviewers blinded to the subjects' randomization status.
