Cross-cultural validation of a smoking abstinence self-efficacy scale in Korean American men.
ABSTRACT The main purpose of the study was to examine the psychometric properties of a Smoking Abstinence Self-Efficacy Scale with Korean men in the US. The scale was modified to reflect the Korean cultural practice of smoking behavior and was cross-culturally validated with a panel of 10 professionals. An 11-item Korean version of the scale was administered twice over a one-month period. Data were analyzed for internal consistency reliability, stability, and construct validity. After the deletion of one item, an exploratory factor analysis yielded two factors, which explained 62% of the variance. Internal consistency was satisfactory for the total scale (.89), Factor I (.88), and Factor II (.80) but intraclass correlation coefficient for the total scale (.57) was low. Nicotine dependence and nicotine withdrawal showed modest but statistically significant correlations with the scale.

ABSTRACT: The study was conducted to examine the relative effectiveness of cognitive behavior therapy with a cultural tailoring intervention compared to brief medication management. The study used a two-arm randomized controlled trial in which participant assignment was stratified by gender. The intervention condition received eight weekly 40-min individualized counseling sessions of culturally tailored cognitive behavior therapy, while the control condition received eight weekly 10-min individualized counseling sessions of medication management. Both conditions received nicotine patches for 8 weeks. Data were collected at baseline and at four follow-up points (one and 4 weeks, and three and 6 months post-quit). Treatment outcomes were presented as an intention-to-treat analysis. Thirty Korean immigrants participated in the study. At 6-month follow-up, 57.1% of participants in the intervention and 18.8% of participants in the control had 7-day point prevalence abstinence (odds ratio = 5.8, 95% confidence interval = 1.12-26.04, P = 0.04). Participants' self-reported abstinence was biochemically verified with exhaled carbon monoxide and salivary cotinine levels. A combination of the culturally tailored cognitive behavior therapy and nicotine replacement therapy had a better treatment outcome compared to brief medication management. The promising result suggests a need to further test the intervention in larger samples and longer follow-up assessments before it can be adapted in clinical settings.Journal of Immigrant and Minority Health 07/2011; 14(3):395-404. · 1.16 Impact Factor
Conference Proceeding: A silicon micromachined six-degree of freedom piezoresistive accelerometer[show abstract] [hide abstract]
ABSTRACT: This paper presents a miniaturized piezoresistive six-degree of freedom (6DOF) accelerometer utilizing a highly symmetric quad-beam structure with symmetrically bonded identical two seismic masses. The FEM simulations of static and modal analysis were performed to optimize structural parameters and analyze the mechanical response at accelerations of different directions. The accelerometer is capable of measuring three components of linear acceleration and three components of angular acceleration on three orthogonal axes up to ±10 g in the frequency bandwidth of 300 Hz. Comparison of the obtained experimental results and finite element simulation shows good agreement. The sensor is ideal for use in biomechanical research applications such as study of human gesture recognition systems.Sensors, 2004. Proceedings of IEEE; 11/2004

ABSTRACT: Acculturation and social network support have been identified as predictors of mental health for immigrant and elderly populations. The present study examined both independent and interactive effects of acculturation and social network support on depressive symptomatology among elderly Korean immigrants. Self-reported measures included sociodemographic characteristics, acculturation, social network support, and depressive symptoms. This study used cross-sectional analysis of a community-based cohort. After controlling for the effects of demographic variables, a robust hierarchical regression model indicated that social network support was negatively associated with depressive symptoms. Also, the interaction between acculturation and social network was significantly associated with lower levels of depressive symptoms (β = -0.29, p < 0.05). In other words, elderly Korean immigrants who had high social network support and were highly acculturated exhibited lower levels of depression compared to those who had low support and were highly acculturated. Our findings call attention to the role of social network support in the mental health of elderly Korean immigrants. Service providers can develop strategies for decreasing depression by increasing social network support, especially with family members, among their elderly parents.Aging and Mental Health 03/2012; 16(6):787-94. · 1.68 Impact Factor
