Background and aims. Parents' empowerment is advocated to promote and preserve an informed and autonomous decision regarding their children' immunization. The scope of this study is to develop and evaluate the psychometric properties of an instrument to measure parents' psychological empowerment in their children's vaccination decision and propose a context-specific definition of this construct. Materials and Methods. Grounding in previous qualitative data, we generated an initial pool of items which was later content and face validated by a panel of experts. A pretest allowed us to reduce the initial pool to 9 items. Convergent and discriminant validity measures included the General Self-Efficacy Scale, a Psychological Empowerment Scale, and the Control Preference Scale. Vaccination-related outcomes such as attitude and intention were also included. Results. Principal Component Analysis revealed a 2-factor structure, with each factor composed of 2 items. The first factor concerns the perceived influence of one's personal and family experience with vaccination, while the second factor represents the desire not to ask other parents about their experience with vaccination and their lack of interest in other parents' vaccination opinion. Conclusions. In light of its association with positive immunization- related outcomes, public health efforts should be directed to reinforce parents' empowerment. [ABSTRACT FROM AUTHOR]

Background. The majority of current health literacy tools assess functional skills including reading, writing, and numeracy. Although these tools have been able to underline the impact of such skills on individuals' health behaviour, there is a need for comprehensive measures to examine more advanced skills. The individual's ability to use health-related information considering his/her own health context, and judging positive and negative consequences of their decisions has been conceptualized as judgment skills. The present study used a newly developed judgment skills tool to explore asthma selfmanagement practices. Design and methods. Eighty asthma patients were recruited from medical offices during the year 2013. The questionnaire was selfadministered and contained health literacy questions, the judgment skill tool, the Asthma Control Test, and several self-management questions. Results. Sixty-nine percent of participants had adequate health literacy, while 24% and 5% had marginal and inadequate levels, respectively. The high-judgment group referred more to their doctor when experiencing asthma problems t(76)=-2.18, P<0.032; complied more with the use of their control medicine t(77)=-3.24, P<0.002 and went more regularly to the doctor t(78)=-1.80, P<0.038 (one-tailed) than the low-judgment group. Conclusions. The judgment skills tool can help identify asthma patients' health information use and reveal how this use may affect some self-management practices. [ABSTRACT FROM AUTHOR]
