Factors Related with Tobacco Smoking among College Students: The Application of the Extended Theory of Planned Behavior

Factors related to treatment adherence behaviors among old-age hemodialysis patients in Hamadan, Iran: the application of the extended theory of planned behavior during Covid-19 pandemic

Purpose

This study aimed to identify the factors related to treatment adherence behaviors among old-age hemodialysis patients in Hamadan based on the Extended Theory of Planned Behavior (ETPB) during the covid-19 pandemic.

Methods

This cross-sectional study was conducted from January to March 2021 in Hamadan, Iran. 191 hemodialysis patients were recruited who were referred to hemodialysis centers via the census method. Data were collected by a questionnaire containing items on socio-demographic information, End-Stage Renal Disease Adherence (ESRD-Adherence) Questionnaire, and ETPB constructs scale. Data analysis was performed using descriptive statistics and structural equation modeling.

Results

The mean (SD) age of participants was 62.49 (10.66). Also, the mean (SD) hemodialysis vintage/Month of them was 36.56 (43.34). Moreover, Treatment Adherence Behaviors are associated with education level, sex, and marital status (p < 0.001). Besides, Perceive Behavior Control (β = 0.414, t-value = 3.810) associated with intention. Also, intention (β = 0.158, t-value = 1.976) was associated to adherence behaviors. No significant associations were observed between positive attitudes, subjective norms, a perceived threat with intention, and adherence behaviors. The model explained about 54% of the variance of adherence behaviors. Finally, the goodness of fit index of 0.78, indicating the model good fit.

Conclusion

The present study demonstrates that some of the ETPB constructs such as perceived behavior control and intention are useful to improve adherence among the oldest hemodialysis patients. Also. This framework is revealed alongside the theory of planned behavior (TPB) applicable in the treatment adherence of old-age hemodialysis patients.

The application of the theory of planned behavior to nutritional behaviors related to cardiovascular disease among the women

BACKGROUND

Nutritional factors have been identified as preventable risk factors for cardiovascular disease; this study aimed to investigate the application of the Theory of Planned Behavior (TPB) in nutritional behaviors related to cardiovascular diseases among the women in Fasa city, Fars province, Iran.

METHODS

The study was conducted in two stages. First, the factors affecting nutritional behaviors associated with cardiovascular disease on 350 women who were referred to Fasa urban health centers were determined based on the TPB. In the second stage, based on the results of a cross-sectional study, quasi-expeimental study was performed on 200 women covered by Fasa health centers. The questionnaire used for the study was a questionnaire based on TPB. The questionnaire was completed by the experimental and control groups before and three months after the intervention. Data were analyzed by SPSS software using logistic regression, paired t-test, independent sample t-test, and chi-square test. The level of significance is considered 0.05.

RESULT

The constructs of attitude, subjective norms, and perceived behavioral control (PBC) were predictors of nutritional behaviors associated with cardiovascular disease in women. The constructs predicted 41.6% of the behavior. The results showed that mean scores of attitude, subjective norms, PBC, intention, nutritional performance related to the cardiovascular disease before intervention were, respectively, 24.32, 14.20, 18.10, 13.37 and 16.28, and after the intervention, were, respectively, 42.32, 25.40, 33.72, 30.13 and 41.38. All the constructs except the attitude in the intervention group were significantly higher (p < 0.001) than the control group.

CONCLUSION

The results of the present study showed that the educational intervention based on the TPB would be consider an effective educational and promotinal strategy for the nutritional behaviors to prevent cardiovascular disease in women. Considering the role of mothers in providing family food baskets and the effect of their nutritional behaviors on family members, the education of this group can promote healthy eating behaviors in the community and family.

Factors associated with suicidal ideation in drug addicts based on the theory of planned behavior

BACKGROUND

Several studies have attempted to understand the link among drug addicts and suicidal ideation. The purpose of this study was to investigate the factors associated with suicidal ideation in drug addicts based on the Theory of Planned Behavior (TPB).

METHOD

This cross-sectional study was conducted with 2160 of drug addicts in private and public clinics for quitting addiction through methadone treatment in Shiraz city, Fars province, Iran from October 2018 to June 2019. Data gathering tools were a questionnaire on demographic characteristics, the Beck Scale for Suicidal Ideation and a questionnaire based on constructs of TPB. Data were analysed by SPSS 22 using descriptive statistics (mean, standard deviation, and frequency) and statistical tests (independent t-test, Pearson correlation coefficient, and linear regression). The significance level was considered 0.05.

RESULTS

The mean age of the participants was 39.24 ± 11.92; 80.28% of them had a history of quit and 43.19% of them had a history of arrest and imprisonment. According to the results, 19.63% of the participants had suicidal ideation and 10.97% had a history of suicide attempt during their lifetime. The constructs of attitude, subjective norms, perceived behavioral control, and intent predicted suicidal ideation in the subjects. Intent and perceived behavioral control constructs were the strongest predictors of suicidal ideation, respectively. In general, the studied variables predicted 54.8% of suicidal ideation.

CONCLUSION

The structures of attitude, subjective norms and perceived behavioral control and intent predicted suicidal ideation in the drug addicts, so the theory of planned behavior will be a good framework for educational interventions to reduce suicide in them.
