Culture might also affect the treatment-seeking behavior related to smoking cessation. Data from the tobacco helpline in California showed that about 40 percent of the Asian callers to the tobacco helpline were friends or family members compared to six percent of the calls for non-Asian (Zhu SH, 2002). This suggests that Asian Americans and Pacific Islanders may be less likely to ask for help for themselves or that family members are more likely to ask for help for their loved one. This implicates the need to involve family members in treatment from the very beginning, which is a different concept than that seen in the themes of self reliance and personal responsibility among Western cultures (Fong, 2007). In general, it is recognized that Asian Americans with addictive disorders face several cultural and practical barriers to treatment and the result has been an underutilization of addiction and mental health treatment. For example, shame in asking for help for an addictive disorder is recognized as one of the most recognized cultural barrier in this population (Fong, 2007). A few preliminary interventions were targeted to Asian Americans (for example, Suc Khoe La Vang for Vietnamese American and Lay-led smoking cessation approach for South East Asian men, etc), and provided some preliminary evidence for the effectiveness of such culturally-appropriate smoking cessation intervention (Chen, 2001).
