Content Validity of a Questionnaire Based on the Theory of Planned Behavior to Assess the Psychosocial Determinants of Insulin Adherence

Abstract IntroductionHand washing is of key importance among residents to prevent life-threatening infections such as severe pneumonia or other microbial infection. Residents received coronavirus disease 2019 (COVID-19) vaccine at vaccination station are obliged to stay in the vaccination station at least 30 minutes. The period of post-vaccination observation is an ideal time for hand washing intervention. This study aimed to determine the effectiveness of a health intervention on hand washing among residents, who received the COVID-19 vaccine, by using the theory of planned behavior (TPB).Methods:This randomized controlled trial was carried out between March 2021 and May 2021 in Wuhan, China. Participants were recruited using randomized cluster sampling and divided into intervention group and control group by random allocation. Data were collected using a self-administered researcher-made questionnaire based on TPB and Hand washing Questionnaire. Validity (content validity index = 0.87; content validity ratio = 0.89) and reliability of the questionnaires were confirmed (α = 0.96). Intervention was implemented during the observation period post-vaccinated (lasting 15 min) using videos and live training based on TPB constructs.Results:A total of 448 residents were participated with a response rate of 71.9% (322). The mean age of the participants was 46 (53% females). Compared with the control group, the scores of subjective norm (P = 0.009) and perceived behavioral control (P < 0.001) in intervention group were higher after one time intervention. Mean scores of attitudes, subjective norms, perceived behavior control and intention of intervention group was significantly higher than the control group after twice intervention (P < 0.001). Moreover, participants in the intervention group performed better than those in the control group on daily hand-washing times (P = 0.044), hand sanitizer use (P = 0.003), rub time (P < 0.001), following the six-step technique (P < 0.001) after intervention.Conclusions:The findings suggested that applying TPB based intervention is suggested to improve hand washing behavior in residents.

Abstract Background Behavior change interventions in tackling road traffic injuries are a public health concern. Thus, this interventional research was to survey the effect of safe traffic behaviors among male students in Hamadan, Iran, utilizing theory of planned behavior. Methods In this quasi-experimental study, 204 students were randomly selected through multistage sampling from male high school students of Hamadan city, west-central of Iran, and non-randomly allocated to control and intervention groups (102 students in every group). The self-administrate questionnaire was used for data collection in this research. Frequency (percentage) and mean (SD) were used for description. Cronbach alpha coefficient, content validity ratio (CVR) and content validity index (CVI) were used for psychometric evaluation of questionnaire and paired/independent sample t-test was used for data analysis. All statistical analyses were done in SPSS 19 and significant level was considered 0.05. Results In both groups, more than 50 % of students walked to school. The two study groups were homogeneous in terms of confounding variables (p > 0.05). The validity of the questionnaire was confirmed and the total Cronbach’s alpha value was equal to 0.97. There was no significant difference in the score of safe traffic behaviors between the two groups before the intervention (p > 0.05). But after the intervention, the score in the intervention group was significantly increased (p < 0.05). Intragroup comparison also showed that only in the intervention group the score was significantly changed (p < 0.05). Conclusion Theory of planned behavior is a suitable conceptual framework for planning the interventions to increase safe traffic behaviors in students.

Abstract. Faking has been a concern in selection research for many years. Many studies have examined faking in questionnaires while far less is known about faking in selection exercises with higher fidelity. This study applies the theory of planned behavior (TPB; Ajzen, 1991 ) to low- (interviews) and high-fidelity (role play, group discussion) exercises, testing whether the TPB predicts reported faking behavior. Data from a mock selection procedure suggests that candidates do report to fake in low- and high-fidelity exercises. Additionally, the TPB showed good predictive validity for faking in a low-fidelity exercise, yet not for faking in high-fidelity exercises.

Abstract. Heart transplantation is the treatment of choice for children with end-stage heart disease. Coronary artery vasculopathy is, however, a significant morbidity and leading cause of late graft loss, and hyperlipidemia a risk factor for its development. Improving diet in this population could have important benefits for patients. We wanted to understand what influences decisions about food intake in this patient group. Dietary intentions and behavior were examined using a questionnaire based on the Theory of Planned Behavior (TPB) with 67 children who had undergone heart transplantation at least 12 months previously. The TPB model was significant for both healthy and unhealthy dietary behaviors, explaining 55% and 38% of the variance, respectively. Ten percent of children reported not eating any fruit and/or vegetables in the previous week and only 29% reported eating fruit and/or vegetables every day. The Theory of Planned Behavior provides a framework for explaining some specific dietary behaviors related to individual food groups in children who have undergone heart transplantation. These preliminary data support using this approach to inform the development of interventions to improve fruit and vegetable consumption but the approach may be less useful for explaining and developing interventions to reduce the consumption of unhealthy foods.
