METHODS: The validated Malay version of the Job Content Questionnaire (JCQ), Depression Anxiety Stress Scales (DASS) and the World Health Organization Quality of Life-Brief (WHOQOL-BREF) were used. A structural equation modelling (SEM) analysis was applied to test the structural relationships of the model using AMOS version 6.0, with the maximum likelihood ratio as the method of estimation.
RESULTS: The results of the SEM supported the hypothesized structural model (chi2 = 22.801, df = 19, p = 0.246). The final model shows that social support (JCQ) was directly related to all 4 factors of the WHOQOL-BREF and inversely related to depression and stress (DASS). Job demand (JCQ) was directly related to stress (DASS) and inversely related to the environmental conditions (WHOQOL-BREF). Job control (JCQ) was directly related to social relationships (WHOQOL-BREF). Stress (DASS) was directly related to anxiety and depression (DASS) and inversely related to physical health, environment conditions and social relationships (WHOQOL-BREF). Anxiety (DASS) was directly related to depression (DASS) and inversely related to physical health (WHOQOL-BREF). Depression (DASS) was inversely related to the psychological wellbeing (WHOQOL-BREF). Finally, stress, anxiety and depression (DASS) mediate the relationships between job demand and social support (JCQ) to the 4 factors of WHOQOL-BREF.
CONCLUSION: These findings suggest that higher social support increases the self-reported quality of life of these workers. Higher job control increases the social relationships, whilst higher job demand increases the self-perceived stress and decreases the self-perceived quality of life related to environmental factors. The mediating role of depression, anxiety and stress on the relationship between working conditions and perceived quality of life in automotive workers should be taken into account in managing stress amongst these workers.
METHOD: The sample consisted of 520 first-year undergraduate international students. The experimental group contained students who were diagnosed with depression and homesickness and received seven sessions of brief individual CBT for depression to reduce homesickness. The control group contained students who were diagnosed with depression and homesickness and received one session of advice and suggestions. The comparison group contained students who experienced only homesickness and did not receive any interventions. The study used the comparison group to determine if an interaction effect existed between students experiencing only homesickness and students experiencing both homesickness and depression.
RESULTS: Students who received brief individual CBT displayed a significant reduction in their homesickness and depression scores compared to the scores of students in the control group. Students who experienced only homesickness exhibited a significant reduction in the scores on homesickness in the post-assessment compared to the control group's post-assessment homesickness scores.
LIMITATION: The results of this study cannot be generalized as data were collected from three universities in Malaysia. The follow-up assessment was conducted six months after the post-assessment, which also limits generalizability beyond six months.
CONCLUSION: Overall, homesickness is considered a normal reaction. Brief individual CBT for depression is effective in reducing homesickness and depression among international students.
