This study sought to investigate the concept of wellness in high school students and in particular whether such variables as gender, age and life satisfaction impact on adolescent wellness. Data were collected from a sample of 240 high school students. Each of these subjects completed a basic demographic form along with the Adolescent Form of the Wellness Star Scale and Life Satisfaction Scale. Data were analyzed with descriptive analysis, t-test and oneway ANOVA. Results of these analyses failed to reveal significant differences between groups based on the variables of age, gender and life satisfaction about total wellness. The results suggested meaningful differences in social and physical subscales between genders. According to results, females have higher score on social subscale while males have higher score on physical subscale. The results also suggested a meaningful difference in social subscale among age groups. The finding showed that social subscale scores of students become lower with the increase in age. At the same time, no meaningful differences were found among different life satisfaction level in terms of subdimension of wellness. The findings were further examined in light of recent research and implications for counseling with adolescent subjects are discussed.
