Background: An understanding of the relationships between mental health literacy and health promotion behaviours is essential for the development of community-based interventions in the prevention of mental disorder. Objectives: The aim of this study was to examine the relationships between mental health literacy and health-promoting behaviours and to assess the contributions of mental health literacy through mediation to demographic characteristic in healthpromoting behaviours. Methods: This cross-sectional study was performed on 378 participants by convenience method in public places of Bushehr city from January to March 2016. The data collection tool included demographic variables section, mental health literacy scale, and health-promoting lifestyle profile. Assessment of the potential mediation effect of MHL was assessed using the three criteria. The association of the demographic characteristic with the MHL must be significant, the association of the demographic characteristic with health-promoting behaviours must be significant, and MHL must be significantly associated with the health-promoting behaviours controlling the demographic characteristics. The analysis was done by SPSS software version 20.0. Results: Findings indicated that there is a significant association between the education level (P < 0.001) and history of mental disorder (P = 0.004) with MHL score. There is a significant association between education (P < 0.001), employment status (P = 0.028), marital status (P = 0.013), and history of mental disorder (P = 0.035) with HPLP score. The hierarchical multiple regression analysis indicated that the education tended to have both direct and indirect effect in HPLP. Conclusions: MHL is a significant predictor and mediator to all the health-promoting behaviours. MHL is predictor of healthrelated behaviours, and, it also mediates the effect of the academic education on these behaviours.
IntroductionPhysical activity is the most important self-management behaviour in diabetes. The aim of this study was to evaluate the impact of a short message service (SMS) based on a health promotion model (HPM) on the physical activity of diabetic patients.MethodsThis quasi-experimental study consisted of 37 type II diabetes patients in an SMS group and 36 type II diabetes patients in a control group. The patients in both groups completed written consent forms and questionnaires at the beginning of the study. The patients in the SMS group received training messages within two weeks (two or three messages daily) in the field of physical activity based on HPM constructs. Both groups completed questionnaires in three stages (at the beginning of the study, four weeks after the first visit, and three months later) comprising demographic factors, questions regarding the constructs, and 7-day physical activity recall. After data collection, statistical analysis was conducted using an independent t-test, a Chi-square test, and a repeated measures analysis of variance (ANOVA).ResultsAs compared with the control group, changes in mean scores of perceived self-efficacy (P = 0.001) and family support (P = 0.046) of physical activity in the training group were significantly greater and perceived barriers (P < 0.001) were significantly lower over time. The physical activity performance of the SMS group was better three months after training as compared with that of the control group (P < 0.001).ConclusionThe results demonstrated the efficacy of training messages in changing the beliefs and physical activity behaviours of diabetic patients.
Planning of education based on the HPM and implementation through multimedia can change belief about physical activity and increase participation in physical activity.
