Organ transplantation is one of the options to increase the life expectancy and quality of life (QOL) of patients waiting on the organ transplant list. The lack of body parts for transplants remains a worldwide concern. This study was designed and implemented to assess organ donation intention among the staff of government and non-government offices in Qom based on the theory of planned behavior (TPB).

Using stratified random sampling, this cross-sectional and analytical study was conducted on 440 employees in Qom, Iran, in 2022. The data collection instrument was a researcher-designed questionnaire, including demographic characteristics, possession of an organ donation card or blood donation history, and constructs of the TPB. The data were analyzed using descriptive statistics, the Pearson correlation coefficient, multiple regression analysis, and structural equation modeling.

The mean ± standard deviation age of participants was 38.21 ± 3.6. The results showed that 29.2% of participants (n = 116) had a signed blood donation card, and 107 participants (27%) had a blood donation history. The structural model fits the data well [χ2/df = 2.84, P < 0.001), CFI = 0.916, GFI = 0.902, RMSEA = 0.053]. The TPB constructs could predict 75% of the variance of the behavioral intention (P < 0.001). Finally, no statistically significant relationship was found between knowledge and intention to donate organs (β = 0.003, P = 0.93).

The result of the regression analysis of the relationship between TPB variables and organ donation intention indicated that perceived behavioral control (PBC) had a great influence on the organ donation intention of government and non-government employees.

 Athletes’ use of androgenic-anabolic steroids (AASs) is a significant health problem. This study aimed to determine factors associated with AAS in male bodybuilders by applying the theory of planned behavior (TPB).

 Using a multistage random sampling procedure, this descriptive-analytical cross-sectional study was performed on 429 athletes participating in gyms in Qom, Iran, in 2019. The data collection tool was a questionnaire, including demographic information and questions related to TPB constructs. Data were analyzed by descriptive statistics, Chi-square test, logistic regression, and linear regression using SPSS software, version 16.

 The results demonstrated that 188 (48.2%) athletes had a history of AAS use. The attitude (β=0.39), subjective norm (β=0.26), and perceived behavioral control (β=-0.36) predicted 38% of the variance of intention to AAS use. Further, behavioral intention was the statistically significant predictor of AAS use among the studied athletes (OR=0.83, 95% CI: 0.78-0.87). Variables such as having friends (OR=2.06, 95% CI: 1.28-3.30) or a sports coach using AAS (OR=3.1, 95% CI: 1.58-6.42) and having a history of supplementation use (OR=5.8, 95% CI: 2.65-12.8), along with age (OR=4.3, 95% CI: 0.35-53.6) had a significantly predictive role in using AAS.

 The findings revealed that nearly half of the studied athletes had a history of using AAS and supplements. TPB is applicable to identify the determinants of beliefs, intention, and behavior to use AAS among athletes. These findings can be useful in designing appropriate programs to prevent AAS use.

Coronavirus disease 2019 (COVID-19) vaccination is expected to end the pandemic; a high coverage rate is required to meet this end. This study aimed to investigate the prevalence of behavioral intention of free/self-paid COVID-19 vaccination and its associations with prosociality and social responsibility among university students in China.

An anonymous online cross-sectional survey was conducted among 6922 university students in five provinces in China during November 1-28, 2020. With informed consent, participants filled out an online survey link distributed to them via WeChat study groups. The response rate was 72.3%.

The prevalence of behavioral intentions of free COVID-19 vaccination was 78.1%, but it dropped to 57.7% if the COVID-19 vaccination involved self-payment (400 RMB; around 42 USD). After adjusting for background factors, prosociality (free vaccination: adjusted odds ratio [ORa] = 1.10, 95% CI: 1.09-1.12; self-paid vaccination: ORa = 1.08, 95% CI: 1.07-1.09) and social responsibility (free vaccination: ORa = 1.17, 95% CI: 1.14-1.19; self-paid vaccination: ORa = 1.13, 95% CI: 1.11-1.14) were positively associated with the two variables of COVID-19 vaccination intention.

The present study demonstrated the positive effects of prosociality and social responsibility on the intention of COVID-19 vaccination. Accordingly, modification of prosociality and social responsibility can potentially improve COVID-19 vaccination. Future longitudinal and intervention studies are warranted to confirm such associations across populations and countries.

The prevalence of coronavirus disease 2019 (COVID-19) vaccination is very critical in controlling COVID-19. This study mainly aimed to (1) investigate behavioral intentions of COVID-19 vaccination under various specific scenarios, and (2) associated factors of the afore-mentioned vaccination intentions. 

A random anonymous telephone survey interviewed 450 Chinese adults from September 16-30, 2020 in Hong Kong, China. Nine scenarios of behavioral intentions of COVID-19 vaccinations were measured combining effectiveness (80% versus 50%), safety (rare versus common mild side effect), and cost (free versus HK$ 500).

The prevalence of behavioral intentions of COVID-19 vaccination under the 9 specific scenarios was very low and varied greatly (4.2% to 38.0%). The prospective countries of manufacture also influenced vaccination intention (eg, Japan: 55.8% vs China: 31.1%). Only 13.1% intended to take up COVID-19 vaccination at the soonest upon its availability. The attributes of effectiveness and side effect influenced vaccination intention most. Positively associated factors of behavioral intentions of COVID-19 vaccination included trust/satisfaction toward the government, exposure to positive social media information about COVID-19 vaccines, descriptive norms, perceived impact on the pandemic, perceived duration of protectiveness, and life satisfaction.

Intention of COVID-19 vaccination was low in the Hong Kong general population, especially among younger people, females, and single people. Health promotion is warranted to enhance the intention. The significant factors identified in this study may be considered when designing such health promotion. Future research is required to confirm the findings in other countries. Such studies should pay attention to the specific context of cost, safety, and effectiveness, which would lead to different responses in the level of behavioral intention of COVID-19 vaccination (BICV).

  One of the cancers that threatens womenchr('39')s health is cervical cancer, so the aim of this study was to investigate the predictors of behavioral intention of Pap smear testing based on the theory of protective motivation in women.

This is an analytical cross-sectional study. Participants in this study were 300 women referring to public clinics in one of the selected hospitals in Tehran. In this study, a reliable and valid questionnaire based on protection motivation theory was used to collect information. Data were analyzed using Spss software version 19 as well as correlation test and stepwise regression. The P value less than 0.05 was considered to be statistically significant.

Out findings revealed that the correlation coefficients of perceived sensitivity (r = 0.47), perceived intensity (r = 0.53), fear (r = 0.46), response costs (r = 0.54), response efficiency (r = 0.2), self-efficacy (r = 0.53), and behavioral intent were significant at a confidence level of 0.99 and in a positive directionThe ability of behavioral intention prediction for response costs (26.2%), self-efficacy (11.6%), fear (1.8%) and perceived sensitivity (3.2%) was recorded, these variables are able to predict about 42.8% of changes in behavioral intention for Pap smear testing.

The behavioral intent of having a Pap smear testing can be predicted based on the theory of protective motivation in women. Therefore, designing educational programs within the framework of this theory is recommended to improve Pap smear testing.

Breast cancer is the most common cancer among women in Iran. Early diagnosis of breast cancer by mammography could decrease the rate of mortality and improve the survival rate. This study aimed to determine the predicting factors of mammography adherence among Iranian women based on transtheoretical model.

This cross-sectional study was done on 300 married women in Yazd in 2018. Subjects was recruited using cluster sampling. Data were gathered through researcher-made questionnaire based on trans-theoretical model. The constructs of decisional balance, self-efficacy, stages and process of change were studied. Data were analyzed using chi-square test, one-way analysis of variance, Spearman correlation coefficient and regression analysis in SPSS-16 software.

The mean age of women was 47.25±6.97 years old (ranged from 40 to 70). Most of the participants (86.4%) were in inactive stages of decision-making for performing mammography and only 5.3% were in active stages. The mean score of self-efficacy among the studied women was 24.54±6.5. According to linear regression test, the validity of the predicting trans-theoretical model by all of its constructs together was 47%.

Results of the present study showed that most of the women were at inactive stages of decision-making for mammography behavior and, based on the results, to improve the stages of the behavior, their self-efficacy should be improved.

Some communicators resort to negative appeals such as fear to encourage consumers to healthy behaviors. Nonetheless, the effectiveness of this type of content is yet questioned. Present study has been conducted to investigate how fear intensity and fear type applied in anti-obesity advertisements prompt preventive behavior among consumers.

208 college students in Tehran province were randomly classified in 7 groups (6 experimental and 1 control group) based on a factorial design; 2 (fear intensity: high and low) x 3 (fear type: physical, social, and reappraisal). Research hypotheses were tested applying appropriate statistical tests including structural equation modeling and analysis of variance, based on data gathered through questionnaire and interventions such as presenting participants with visual contents.

it was revealed that there is a significant and positive relationship between the perceived severity and perceived fear, as well as between perceived susceptibility and perceived fear, and also between perceived fear and behavioral intention. Analysis of variance confirmed the significant main effect of fear intensity on behavioral intention. The main effect of the fear type on behavioral intention was not approved. However, findings indicate the significant interaction effect of fear intensity and fear type on behavioral intention so that highly intense messages that representing physical harm and lowly intense messages that representing social harm stimulate more behavioral intention.

It is concluded that applying fear appeal in health warning advertisements is effective in inviting consumers to healthy behavior, especially once a proper combination of the type and intensity of fear is applied in messages.

In modern communities, smoking is one of the most important causes of illness, disability, and premature death. It is regarded as a pervasive health problem in the world. The risk of death in the tobacco consumers is 80-90 percent higher than ordinary people. In this regard, this study aimed to investigate the variables of behavioral intention and subjective norms in reducing the smoking water pipe in intervention and control groups after an educational intervention in women over 15 years in Bandar Abbas in 2015.

 In this quasi-experimental study, 128 women over 15 years who had at least one waterpipe smoking a day were selected by the multi-stage cluster. They were classified into two groups of intervention and control groups. Data were collected using a validated and reliable questionnaire based on the Theory of Planned Behavior constructs and demographic information before and after the intervention. Collected data were assessed using an independent paired t-test, t-test, and chi-square test. In all tests, the significance level was set to 0.05.

The results showed that there is a significant difference in mean score between behavioral intention and subjective norms in two groups after the intervention (P<0.05). In addition, compared to the control group, the frequency of waterpipe smoking among women in the intervention group significantly decreased after the intervention (P<0.05).

The results showed that behavioral intention and subjective norms based on constructs of Theory of Planned Behavior might be effective strategies to reduce tobacco use in women.

The present study was conducted with the aim of psychometric evaluation of a tool measuring behavioral intention in relation to interprofessional shared decision-making based on the theory of planned behavior and its assessment among medical and nursing students. This descriptive study was carried out in two stages. In the first stage, the psychometric properties of the interprofessional shared decision-making (IP-SDM) tool were evaluated based on experts’ opinions. In the second stage, the participants’ behavioral intention was evaluated using the mentioned questionnaire. The questionnaire consisted of five domains of cognitive attitude (2 items), emotional attitude (2 items), subjective norms (3 items), perceived behavioral control (3 items), and intention to use interprofessional shared decision-making (3 items). Content validity of the questionnaire was evaluated qualitatively and quantitatively (using the content validity ratio (CVR) and content validity index (CVI)). Cronbach’s alpha coefficient and interclass correlation coefficient (ICC) were used to determine the reliability of the questionnaire. In the second stage, the data were analyzed using descriptive statistics (mean and standard deviation) and Pearson’s correlation test in SPSS software. Qualitative and quantitative content validity of the questionnaire was confirmed based on experts’ opinions. The internal consistency of the tool, based on the Cronbach’s alpha coefficient, was 0.92, and the tool’s repeatability was calculated at 0.84 using ICC. Participants in the study intended to participate in interprofessional shared decision-making. The behavioral intention measurement tool in relation to interprofessional shared decision-making based on the theory of planned behavior has good validity and reliability in Iran. Regarding the participants’ behavioral intention to participate in shared decision-making, it is suggested that a suitable platform for shared decision-making and teamwork between health team members be provided in educational systems.

The perceived usefulness and perceived ease of use have been considered as the main factors affecting the acceptance of the new technologies since last few decades. However, it appears that these only two factors cannot describe the users’ behavior in the environments like the Hospital Information System. From the technology acceptance standpoint at the individual acceptance level, the present paper tends to develop a Technology Acceptance Model with introducing some external factors. This study was conducted in 2017. The research population was included 185 nurses who works in Health Information Management (HIM) departments of Tehran University of Medical Sciences. A questionnaire was developed in order to gather the required data. The validity was obtained by panel of experts and the reliability was examined and then confirmed in a 50 person sample using the Cronbach’s Alpha (α=0.93). The Likert’s five item scale was applied. The data were analyzed using descriptive statistics, exploratory factor analysis, and path analysis. The behavioral intention was affected significantly and positively by the factors of perceived usefulness, perceived ease of use, self-efficacy, end user support, social norm, trust, job relevance, and training, with trust having the highest level of effects. Also perceived ease of use had a significant effect on perceived usefulness along with an indirect effect on behavioral intention through perceived usefulness. The factors of anxiety, voluntariness, and facilitating conditions showed no significant effects on behavioral intention. The factors of trust, perceived usefulness, social norm, end user support, and self-efficacy have an impact on the behavioral intention of the users utilizing the Hospital Information System in the concerning hospitals. These factors could explain 72% of the changes of behavioral intention. Concentrating on them would lead to the improvement of the acceptance and Hospital Information System efficiency.

Hepatitis C virus (HCV) infection is a major complex public health problem. Different resources have proved that healthcare workers more than the general population are at a risk of infection. Therefore, medical field students, due to the future occupational hazards, are included in the risk group.

The purpose of the study was to evaluate the level of knowledge, public and individual risk perception, and behavioral intention about HCV, among medical sciences students of the Isfahan University of Medical Sciences. Settings and Design: This is a descriptive–analytical study that was conducted among 457 students of the Medical Sciences in the Isfahan University of Medical Sciences.

The data was collected using a questionnaire. Sampling was done randomly. Statistical Analysis Used: The data was analyzed using the SPSS18software and statistical tests of Pearson, Spearman, T- test, and the analysis of variance (ANOVA); P < 0.05 was considered significant.

Four hundred and fifty-seven students (41.8% male and 58.2% female) in 29 fields of study (six categories) participated in this research. The mean age was 21.55 ± 2.6 years. The mean and standard deviations of the students' knowledge was 3.71 ± 2.9 (out of 8), and the behavioral intention to accruing information and performance of preventive actions related to HCV was 11.52 ± 3.16 (out of 20). Public risk perception was 20.1 ± 3.5 (out of 30); and personal risk perception was 6.96 ± 1.8 (out of 10). The ANOVA test showed that public perception of the risk among students of different academic fields was different (F = 1.52, P < 0.05).

According to the low knowledge of students of Medical Sciences in the Isfahan University of Medical Sciences about HCV, it was recommended that the University Policymakers design an educational intervention about it, in order to minimize the chances of being infected.

Aim: Considering the fundamental role of parent's function and family dynamics including the importance role of family communication pattern on preventing early - onset substance use in children, the present study aimed to determine the correlation between family communication pattern and mother's preventive behavioral intentionregardingpreventing early - onset substance use in children.
This cross - sectional study was carried out among 234 Iranian mothers in Tehran who were randoml y selected to participate voluntarily in the study. The participants filled out a self - administered questionnaire including I - demographic information; II - family - based behavioral intention regarding preventing early - onset substance use in children; and I II - family communication pattern. Data were analyzed by the SPSS software (ver. 21.0) using Pearson's correlations, independent t - test, and ANOVA at 95% significant level.
Findings: The results reported a correlation between conversation (r=0.509**& P≥0.00 1), conformity orientation (r= - 0.150*& P=0.022) and behavioral intention; as well as between conversation conformity orientation (r= - 0.382*& P≥0.001), and conversation (r=0.218**& P=0.001), conformity orientation (r= - 0.105& P=0.108) and age.
The findings suggest that to develop a preventive program, it will be useful to increase family communication pattern, specially conversation orientation to prevent the onset of substance use in children.
