The Influence of Social Media Lifestyle Interventions on Health Behaviour: A Study on Patients with Major Depressive Disorders and Family Caregivers

Abstract

Background: The World Health Organisation (WHO) predicts that depression will be the second leading cause of diseases by 2020. If depression is not properly treated, it can develop into a depressive disorder and increase the risk of suicide.Besides biopsychosocial factors, lifestyle is said to be a major cause of this disease and has led to an increase in its prevalence. Objective: The objective of this study was to study the intentions of patients with major depressive disorders and family caregivers to change their health behaviour and lifestyle through social media influences. Methods: This was a cross-sectional study. Participants were invited to take part in the research and give their informed consent. The sample consisted of 157 patients diagnosed with major depressive disorders, aged 18 years and over, and 110 family caregivers. Data were collected from the questionnaires designed according to the I-Change Model (ICM). Statistical results to confirm causal relationships were analysed based on Structural Equation Modelling (SEM) and by using the SmartPLS 3 software. Results: Patients and family caregivers were questioned about their perspectives on health matters and the influence on their motivations and intentions to change patients’ health behaviour and lifestyle, particularly social media interventions. The patients received information and counselling about health matters, health awareness, motivation and their intentions to change their health behaviour. The family caregivers were presented with the same information and counselling to motivate them to influence the depressive patients’ intentions to change their health behaviour. Conclusion: It is possible that lifestyle interventions on social media can influence the intention to change health behaviour in both patients and caregivers. However, if the patient lacks interest in participating in the treatment and does not have a good relationship with the clinician or provide relevant information to the experts; this can be an obstacle to changing their health behaviour. Therefore, future research should be conducted to ascertain which interventions are appropriate for patients and to study the long-term effects of any risks from using social media in patients with major depressive disorders.
