Chiang Mai: Chiang Mai University; 2012.Background: Self-reliance is an indicator of successful personal development, especially in early adulthood. It is also the fundamental basis of a self-reliant society. Purpose; This research aimed to study self-reliance factors in early adulthood in terms of biology, psychology and society. These included life satisfaction, parenting styles, family relationships, life skills, human relations in the workplace and personal factors such as age, gender, education, marital status, economic status, dependency and health. Methods: The samples were 471 workers aged between 20-35 years residing in eastern Thailand industrial estates. The tools used in this analysis were data collected from questionnaire based surveys of individual factors, life styles and self-reliance. Statistics applied in the data analysis include frequency, percentage, mean, standard deviation, One­-way ANOVA, t-test and stepwise multiple regression. Results: (1) Most of the participants showed moderate levels of self-reliance, life satisfaction and human relationships within the workplace. Life skills and family relationships were rated at high level. The highest mean in parenting style was authoritative. Different ages, level of savings and exercise result in self-reliance variation, the result being statistically significant at 0.05. (2) Regression showed that life satisfaction, life skills, human relations in the workplace and authoritative parenting style were all factors in self-reliance. These factors could predict 23.1% of self-reliance. Conclusions: Biological factors that had an influence on self-reliance were exercise, psychological factors such as life satisfaction and societal factors like life skills, human relations in the workplace and authoritative parenting style. Personal factors that were related to self-reliance were age and level of savings. The study suggested that knowledge and awarencss of the benefits of self-reliance should be provided to people in their early adulthood to create life-long security and a strong society.engMahidol UniversitySelf-relianceEarly AdulthoodLaborProceeding BookChiang Mai University
