Abstract:
Depression in adolescence is predominant problem because it affects adolescents
themselves, family, and society. This predictive correlational study aimed to determine factors
influencing depression among high school students in Chanthaburi Municipality, Chanthaburi
province. 160 students were recruited in the study by cluster sampling technique. Data were
collected during July to August, 2017. Research instruments included 1) Demographic
Questionnaire, 2) Family Connectedness Questionnaires, 3) the Negative Life Event Scale,
4) Resilience Inventory Questionnaire, 5) Internet Addiction Questionnaire, Center for
Epidemiologic Studies-depression scale questionnaires. The Cronbachs alpha coefficients of the
questionnaires were .75, .93, .88, .84 and .82, respectively. Data was analyzed using descriptive
statistic and stepwise multiple regression analysis.
The research found that 95.7 percents of samples had no depression. The mean score
of overall depression was 12.32 (SD = 4.87). Resilience was the most important influencing factor
of depression (β =-.492, p<.001). The second predictor was internet addiction (β =.225,
p<.05). Both variables could explained 32.5 percent of variance in depression of high school
students (R2
= 0.325, Adjusted R2
= .316, p< .001).
The results suggested that nurses, health care providers, and the personnel who work
with adolescents should develop program to promote mental health for preventing depression in
adolescentsby strengthening resilience and decreasing internet addiction.
