DESCRIPTION:Social Network Analysis (SNA) has demonstrated contagion effect
 s across a wide range of behaviours. The Island Study Linking Aging and Ne
 urodegenerative Disease (ISLAND) is an ongoing longitudinal study with ove
 r 3000 actively engaged Tasmanians aged 50 and above\, who report annually
  on social engagement and other health behaviours. ISLAND participants who
  report more social engagement report healthier behaviour across alcohol c
 onsumption\, smoking\, physical activity\, cognitive activity\, diet\, blo
 od pressure\, body weight\, cholesterol\, blood sugar\, and diet\, with ev
 idence that social engagement is an upstream driver of many of these behav
 iours. In this study\, we aimed to understand participants’ experiences 
 of the relationship between social engagement and other healthy behaviours
 .\n\nWe engaged a purposively sampled subset of ISLAND project participant
 s (n=27\, 90% of 30 invitees) in semi-structured interviews\, analysed thr
 ough reflexive thematic analysis. Purposive sampling ensured a wide range 
 of individual characteristics (e.g. gender\, education\, age)\, social cir
 cumstances (e.g. living alone or cohabiting\, working or retired)\, and so
 cial preferences (introversion/extraversion).\nAt one extreme\, some parti
 cipants experienced health choices as independent agents\, with no known s
 ocial influences impacting their behaviour. At the other extreme\, some ex
 perienced health choices as highly socially driven or constrained\, with h
 ealth behaviour being dependant on the actions and opinions of others. Mos
 t participants located themselves at intermediate points in this continuum
 : experiencing some influence through knowledge\, motivation\, and/or beha
 viour co-participation\, while still experiencing autonomy in their final 
 health decisions. Some participants positioned themselves differently when
  different health behaviours were discussed\; for example\, dietary choice
 s may be more socially influenced\, while choices to attend medical appoin
 tments may be more individually determined. Where influence was experience
 d\, a wide range of influential actors were reported\, including friends\,
  family members\, and animal companions.    \n\nThis longitudinal cohort p
 rovides the opportunity to quantitatively study the role of social influen
 ce in prompting a range of healthy behaviours among older adults. The unde
 rstandings developed in this initial exploratory project may provide the f
 oundation for further exploration using social network analysis.
