AB  - BACKGROUND: The ecological model of health and ageing has proposed that 
      functional ability (FA) is determined by the interaction between intrinsic 
      capacity (IC) and environmental characteristics. This study empirically examined 
      how social support, as an important social environmental resource, interacts with 
      IC to affect FA trajectories among older adults. METHODS: This was a prospective 
      three-wave cohort study with a sample of 775 community-dwelling older adults. 
      Social support, IC and FA were assessed using the Social Support Rating Scale, 
      the revised Integrated Care for Older People screening tool and the Lawton 
      Instrumental Activities of Daily Living Scale, respectively. Latent growth curve 
      models (LGCM) were implemented to test their relationships. RESULTS: FA 
      significantly declined over 3 years, and the detrimental effect of impaired IC on 
      the deterioration rate of FA was buffered by subjective support but was 
      aggravated by support utilization and was not changed by objective support. FA 
      decline among older adults with impaired IC was observed in those with low 
      subjective support or with high support utilization but not in those with high 
      subjective support or with low support utilization. Among older adults with 
      intact IC, FA decline was observed in those with low support utilization but not 
      in those with high support utilization or with low or high subjective support. 
      CONCLUSIONS: Subjective support may prevent FA decline among older adults with 
      impaired IC, while support utilization may benefit older adults with intact IC 
      but may be detrimental for those with impaired IC. Social support interventions 
      to optimize FA trajectories should improve older adults' perceptions of support 
      and bridge the gap in support utilization among older adults with impaired IC.
