An Intervention Program Using the Health Belief Model to Modify Lifestyle in Coronary Heart Disease: Randomized Controlled Trial.

BACKGROUND: Most effective interventions to control coronary heart disease (CHD) and prevent negative outcomes involve behavioral modification. This study examined how such modification based on the Health Belief Model (HBM) might improve lifestyle and clinical outcomes. METHODS: A total of 120 people with CHD seeking help at a general hospital in Iran were randomly assigned to either the intervention or control group. Information was collected using an HBM-specific questionnaire and the Health Promoting Lifestyle II (HPLP-II) scale. Clinical outcomes (blood pressure, body mass index, and fasting blood sugar) were also measured. The intervention group received a tailored education based on HBM principles plus routine care, while those in the control group received only routine care. Three months after the intervention, both groups were reassessed using Student's t test and analysis of covariance. RESULTS: All HBM subscale scores indicated significant improvements in the intervention group, in contrast to the control group, where scores worsened or stayed the same. Perceived severity and susceptibility were the dimensions that changed most. Total score on the HPLP-II improved significantly in the intervention group (p < 0.001, F = 747.5); however, subscale scores on spiritual growth and interpersonal relationships did not demonstrate significant between-group differences at follow-up. After adjustment for baseline scores, significant improvements in lifestyle subscales were also accompanied by significant improvements in clinical measures. CONCLUSIONS: This HBM-based behavior modification program improved both lifestyle and clinical measures in patients with CHD. Utilizing this program in patients with other cardiovascular diseases may in the future demonstrate similar results.

A mediating role for mental health in associations between COVID-19-related self-stigma, PTSD, quality of life, and insomnia among patients recovered from COVID-19.

INTRODUCTION: Patients with COVID-19 often suffer from psychological problems such as post-traumatic stress disorder (PTSD) and self-stigmatization that may negatively impact their quality of life and sleep. This study examined mental health as a potential mediating factor linking self-stigmatization and PTSD to quality of life and sleep. METHODS: Using a cross-sectional design, 844 people who had recovered from COVID-19 were called and interviewed. Data were collected using structured scales. Structural equation modeling was applied to assess fitness of a mediation model including self-stigma and PTSD as independent factors and quality of life and insomnia as dependent variables. RESULTS: Mental health, COVID-19-related self-stigma, and mental quality of life were associated. Insomnia, PTSD, and COVID-19-related self-stigma displayed significant direct associations (r = .334 to 0.454; p < .01). A mediation model indicated satisfactory goodness of fit (CFI = 0.968, TLI = 0.950, SRMR = 0.071, RMSEA = 0.068). Mental health as a mediator had negative relationships with COVID-19-related self-stigma, PTSD, and insomnia and positive associations with quality of life. CONCLUSION: Mental health may mediate effects of COVID-19-related self-stigma and PTSD on quality of life and insomnia. Designing programs to improve mental health among patients with COVID-19 may include efforts to reduce negative effects of PTSD and COVID-19-related self-stigma on quality of life and insomnia.

Effect of a health-education program using motivational interviewing on oral health behavior and self-efficacy in pregnant women: a randomized controlled trial.

Oral health problems are common among pregnant women. The objective of this study was to examine the effectiveness of motivational interviewing (MI) as a behavior-change technique to enhance self-efficacy and oral health among pregnant women. A randomized controlled trial was conducted with 112 pregnant Iranian women. Women in the intervention group received an education program on oral health using MI during two face-to-face sessions, along with routine health education (two 1-h lectures on oral health changes and needs during pregnancy presented as a lecture by an oral health technician over a 2-wk period). Those in the control group received two 1-h lectures on oral health changes and needs during pregnancy. Oral health behaviors, oral health self-efficacy, and general self-efficacy, were assessed, along with gingival and dental health from baseline to the 3-month follow-up. Analysis of covariance was used to determine differences between intervention and control groups. Scores for both general and specific self-efficacy and for healthy behaviors increased in the intervention group, whereas there was no significant change within controls from baseline to follow-up. Between-group analyses also indicated a significant difference in the scores for self-efficacy and behavior favoring the intervention group. Scores on the gingival inflammation index decreased, as did the number of decayed teeth in the intervention group relative to the control group. The number of filled teeth increased significantly in the intervention group. Health education interventions using MI techniques may help to improve oral health-related self-efficacy and behaviors among pregnant women.
