The present study investigated the psychological and  social correlated of work value and religious orientation of southern Thai adolescents. There were four research objectives. First, to examine the relationships among child-rearing practices, psychological traits and ego dentity development as well as religious orientation. Secondly, to explore the relationships among school experience, psychological traits and work value. Thirdly, to study the relationships among ego identity development, work value and religious orientation. Finally, to compare the predictive power of three groups of  factors on ego identity development, work value and religious orientation. 
                In this field study, the research sample consisted of 480  male and female, Buddhist and Islamic adolescents in two class-levels in senior highschools (Mathayomsuksa 4 and 6) and two comparable class-levels in technical or vocational schools (Firstandthirdyears vocational certficate) for the total of 6 institutes in Pattani and Yala, whose ages ranged from 15 to 21 years. (average age was 17.06 years) These adolescents were asked to respond to a set of questionnaires when they were assembled in  their  own 
classroom. Each questionnaires booklet consisted of parts. The first part consisted of 5 measures each of which were 20  six-choice items, assesing the levels of perception of love-orientation typed and reasoning-oriented type of child-rearing practices, closedfriend' s characteristics, work experience of the adloescents and mental health status. Other four sets of  questionnaireswere 23  to 25  six-choice items, measuring adolescents' socio-emotional 
dovelopment, ego identity development, work value and religious orientation. The last set of the questionnaires was employed to measure various background characteristics of the respondents. 
               For the purpose of data analyses, the measured variables were divided into 5 groups. The first group consisted of 14  background variables. The second group consisted of 2 types of child-rearing practices. The third group consisted of 2 indices  of school experience. The forth group were two psychological traits of the adolescents. The fifth group consisted of ego identity development, work value and religious orientation. The variables in the first, the second and the third groups were employed as in dependent variables. However, the  variables in the forth group were on difernt occasions used as the independent and  dependent variable, and the variables in the fifth group were used as dependent variables in the statisticalin analyses. Six hypotheses were tested in this study by carring out the Analysis of Variance (2  and 3 way Factorial desigs), Pearson' s Product-Monent Correlation Coefficient and the stepwised Multiple Regression Analysis on variour parts of the data. 
           Three out of six hypotheses were strongly supported as well as some parts of one hypothesis. Four major findings are reported as follows: First, it was found that the adolescents with highly developed ego identity were the ones who possessed high socio-emotional level of development, good mental health and had friends with fovorable characteristics. These three predictors could account for 58% of the variance in ego identity scores of the total sample and 70% in the adolessents who were less religious. 
           Secondly, the adolescents who showed high intrinsic work values were the ones who were high on the socio-emotional development, had friends with favorable characteristics and had high work experience. Those three variables together could account for 21 % of variance of the work value scores in the total sample and 30% in the students who lived separately from their parents. 
            Thirdly, religious orientation were highly positive related to friends with favorable characteristics, socio-emotional development and reasoning oriented practice level of the adolescents. This three vaiables were able to predict religious orientation and the coefficient of determination in less religious adolescents was 39% 
            Finally, the results showed that there was a significantly positive correlation between ego identity development and work value, and between eho identity development and religious orientation in all of types of the southern Thai adolescents. 
          The research results in this study have shown that the quality of friends, child-rearing practices, work experience, mental health and the socio-emotional development are highly important for human resource development in Thailand.
