Level of physical activity as a key determinant of healthy lifestyle less than is required in individuals particularly women. Applying theories of behavioral change about complex behaviors such as physical activity leads to identify effective factors and their relations. The aim of this study was to determine predictors of physical activity behavior based on the Theory of Planned Behavior in military staff's wives in Tehran. This cross-sectional study was performed in 180 military personnel’s spouses residing in organizational houses, in Tehran, Iran in 2014. The participants were randomly selected with multi-stage cluster sampling. The validity and reliability of the theory based scale evaluated before conducting the path analysis. Statistical analysis was carried out using SPSS16 and LISREL8.8. The results indicated the model explained 77% and 17% of intention and behavior variance. Subjective norms (Beta=0.83) and intention (Beta=0.37) were the strongest predictors of intention and behavior, respectively. The instrumental and affective attitude had no significant path to intention and behavior. The direct relation of perceived behavioral control to behavior was non-significant. This research demonstrated relative importance and relationships of Theory of Planned Behavior constructs in physical activity behavior of military personnel’s spouses in Tehran. It is essential to consider these determinants in designing of educational interventions for promoting and maintaining physical activity behavior in this target group.

Objectives: The purpose of this study was analysed differences between attitudes, subjective norms, and PBC between groups of individuals who do physical exercise and those who do not. Method: In order to investigate the different effects of attitudes, subjective norms, PBC on intention in both groups a structural equation modelling was employed. 886 subjects completed a questionnaire measuring the components of TPB model. The first group was formed by 332 people who did not practise and the second group was formed by 554 people who practised physical exercise. Results: Results confirmed differences between two groups of people in the prediction capacity of TPB model. In the first group, all variables explained 65% of the variance in intention. In the second group subjective norm and perceived behavioural control had a significant impact on intention and the three variables explained 67% of its variance. t Conclusions: Findings supported the important role of TPB in the context of p...

Background: Theory of planned behavior (TPB) has not been adequately addressed in the field of physical activity among Iranian women. Objectives: This study aimed to determine factors affecting physical activity behavior among women based on the theory of planned behavior. Methods: This cross-sectional study was conducted on 398 women in Kerman, Iran. The women were selected through the multistage random sampling method. Data were collected using the international physical activity questionnaire (IPAQ) and a researchermade questionnaire based on the constructs of the theory of planned behavior and analyzed using structural equation modeling (SEM). Results: The mean age (SD) of participants was 36.9 (9.9). Perceived behavioral control (β = 0. 16, P = 0. 013) and behavioral intention (β = 0.16, P = 0.005) had a significant positive direct effect on physical activity behavior. Moreover, instrumental attitude (β = 0.04, P = 0.003), subjective norms (β = 0.04, P = 0.003) and perceived behavioral control (β = 0.03, P = 0.002) had a significant positive indirect effect on physical activity behavior. Behavioral intention and perceived behavioral control constructs predicted 6% of variance of physical activity behavior. Conclusions: Given that the constructs of behavioral intention and perceived behavioral control could predict physical activity behavior, health promotion interventions should be designed with an emphasis on these factors in order to promote physical activity in women.

Aim: Insufficient physical activity in women exposes them to problems such as overweight, diabetes, depression and cardiovascular diseases on top. In between, employees have minimum physical activity due to type of their job. The goal of this study was determining psychological factors effective on the physical activity of women working in University of Tehran based on the theory of planned behavior. Methods: The research population included female office workers from the University of Tehran, who were selected through a call at this university in 2014 for this descriptive analytical cross-sectional study. For data gathering, a questionnaire was used with acceptable validity and reliability including demographic information and constructs of the Theory of Planned Behavior (TPB) as well as International Physical Activity Questionnaire (IPAQ). Data were analyzed using SPSS21. The statistical bivariate correlation test and stepwise regression test were employed at the significance leve...

Background: Office workers are high-risk populations for their sedentary behavior and its related diseases. This study examined the structured intervention on physical activities in employees. Methods: In this quasi-experimental study, 189 participants were allocated to two experimental and control groups using the multistage random sampling method. Data were collected through the short form of an international physical activity questionnaire, and a structured researcher-made questionnaire containing demographic and questions related to the constructs of the theory of planned behavior (TPB). The experimental group contributed to four training sessions and four practical walking meetings. Data were analyzed by SPSS software (version 19) using independent t test, chi-square, and linear regression tests at the significance level of 0.05. Results: There was no significant difference between the two groups before the intervention regarding the mean score of attitude, subjective norms, perceived behavioral control, behavioral intention, physical activity, and demographic variables (P > 0.05). After the intervention, the mean score of attitude, subjective norms, perceived behavior control, behavioral intention, and physical activity in the experimental group was significantly higher than the control group (P < 0.05). Conclusion: The finding of this study suggests that TPB is a suitable framework for designing physical activity interventions among office workers.
Development and Validation of the Theory of Planned Behavior Questionnaire in Physical Activity
The Spanish journal of psychology, 2012
The Theory of Planned Behavior (TPB) is one of the main theoretical models in the study of the different variables, which influence in the practise of physical activity. The aim in this study was to develop a questionnaire based on TPB in physical activity context providing evidence for the validity of the obtained measures. The instrumental project included three independent studies. The first study entailed the construction and qualitative assessment of the items. In the second study, the analysis of factorial structure was performed by means of exploratory measures, and it showed that the reliability of measures was adequate. The third study provided evidence on the dimensionality of the scale. The confirmatory factorial analysis guaranteed the stability of factorial structure proposed by the TPB and provided evidence for the internal validity of the inventory. Moreover, this study provided evidence of its external validity.
An Application of the Theory of Planned Behavior to Exercise Among Older Adults1
Journal of Applied Social Psychology, 1998
One hundred five older adults enrolled in exercise classes were recruited from local YMCAs. Exercise behavior was measured 1, 3, and 9 months after beginning the exercise class. Intentions were not a significant predictor of exercise behavior, probably because of a lack of variance; most people intended to exercise. The direct measures of attitudes, subjective norms, and perceived behavioral control, however, explained 9% of exercise behavior at 1 month. They did not significantly explain behavior at 3 and 9 months. When the indirect measure of subjective norms explained 18% of exercise behavior at 1 month. The indirect measure of perceived behavioral control accounted for 27% of the variance at I month and 10% at 3 months.
Applying An Extended Version of the Theory of Planned Behaviour to Physical Activity
Journal of sports sciences, 2003
This prospective study explored whether extending the Theory of Planned Behaviour (TPB) with additional variables (descriptive norm, moral norm, anticipated affective reaction, self-identity and past behaviour) would account for additional variance in physical activity intentions and behaviour. Four interactions with past behaviour were also investigated. UK college employees participated in this study (n = 200, Time 1; n = 146, Time 2). Moral norm, self-identity and past behaviour each explained additional variance in intentions, over and above the TPB variables. Past behaviour moderated the impact of descriptive norm on intentions. Intentions, self-identity and past behaviour were significant predictors of behaviour, as measured by a self-report physical activity questionnaire. To increase physical activity, interventions might target moral norm and selfidentity for physical activity. Focusing on positive descriptive norms might benefit sedentary individuals. The significant role of past behaviour is less useful in directing interventions.

Objectives: The present study assessed the generalizability of the Theory of Planned Behavior (TPB) applied to physical activity and to examine if the TPB operates equivalently across gender, age, and ethnic sub-groups. Design/Methods: Measurement equivalence was evaluated for gender (male/female), age (19-34/35-54/ 55þ) and ethnicity (Japanese/Hawaiian or part Hawaiian/Filipino/White) in a random sample (n ¼ 3533) using Multisample Structural Equation Modeling. Results: Measurement equivalence was found for all variables and for their intercorrelations. Of the 100 possible TPB variable relationships between groups, only 6 were significant. The differences were found in explained variances of physical activity. Conclusions: The findings indicate that TPB measures apply over a range of population sub-groups, and should be considered comprehensively when designing interventions.

Back ground and aim The regular physical activity can lead to physical, psychological and social health. Studies have shown that %80 of Iranian people does not exercise. Therefore, due to the importance of exercise performance and concepts of Theory of Planned Behavior, different studies are needed regarding its related factors according to a theoretical framework. The aim of this descriptive correlational study was to determine factors related to exercise performance according to the Theory of Planned Behavior in female students in 2009. Materials and methods 444 female students were selected by stratified sampling method. Data collection tool was a questionnaire including 6 parts: 1- external variables, 2-attitiude to exercise, 3-subjective norms of exercise, 4- perceived control behavior toward exercise, 5- intention to exercise, and 6- exercise. Content validity index, face validity and reliability of the tool were identified by internal consistency and test-retest methods respe...
