This paper examines the views of Hong Kong community leaders on the underlying issues that affect family health, happiness and harmony (3Hs) in Hong Kong. Using a community reconnaissance method, a series of individual in-depth interviews with 26 leaders that represent neighbourhoods of diverse socio-economic status (SES) from June to August 2008 were conducted. Participants considered that changing family structure, economic situation and strong work ethic are the most salient factors that affect family 3Hs. The deprived comprehensive social security assistance recipients, single-parent families and migrant women were considered to be the most vulnerable groups to breakdown in family 3Hs and particularly, they lack family resources. Families from different SES have to overcome different challenges in order to achieve and sustain family 3Hs. Leaders from low SES neighbourhood were concerned more about providing tangible help such as child care facilities to improve family resources, whereas leaders from high SES neighbourhood focused more on preventive interventions such as education on relationship skills to achieve better family well-being. The findings offer insights in designing effective social marketing education campaigns and family-friendly workplace policy to promote social harmony through the maintenance of 3Hs families.
