One of the main features of the relationship between health professionals and their patients is that their effects can be measured. To do this, we need instruments that are well built and that have proven their validity and reliability empirically and experimentally. The objective of this study is to analyse the psychometric properties of the Health Professionals Communication Skills Scale (HP-CSS), which evaluates the communication skills that health professionals use to relate to their patients. The sample consisted of 410 health professionals in the region of Murcia, Spain, and 517 in the province of Alicante, Spain. We obtained descriptive statistics and discrimination indices of the items, the internal structure of the scale using both exploratory and confirmatory factor analysis, the internal consistency, the temporal stability, and the external evidence of validity. The results indicate that the HP-CSS is a valid and reliable instrument and is also useful for the purpose and context in which it will be used.

To prevent dangerous driving behaviors, the Spanish government has implemented public policies focused primarily on increasing the harshness of sanctions for violations of traffic laws. However, empirical evidence has demonstrated that other factors, such as social norms and one's own value system, have an impact on people's motivation to obey the law. A telephone survey was administered to a random sample of 570 Spanish drivers in order to determine the role played by each of these factors in compliance with two of the most flouted traffic rules. Logistic regression of the data allowed for the construction of models and arrive at the following conclusions: (1) social influence exerted by the reference group is a determining factor in compliance with both traffic laws; (2) legitimacy factors play an important role in complying with alcohol limits; and (3) variables from the deterrence approach only influenced compliance with speed limits, and then only moderately. The results of the present study suggest a need for a review of current public policy approaches for the prevention of dangerous driving behaviors.

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.

The relationship between nurses and their patients is changing significantly, resulting in a patient-focused model. This work aims to contribute new knowledge about the effect of communication skills on perceived self-efficacy of nursing professionals. A cross-sectional descriptive study was conducted with a final sample consisting of 242 nurses. Different instruments that measured communication skills and the general and specific self-efficacy of nursing professionals were utilized. A positive and statistically significant correlation (p < 0.01) between the communication skills and the perceived general and specific self-efficacy was obtained. Nursing professionals who have adequate communication skills feel more confident and more competent, fostering good interpersonal relationships with their patients, and therefore, their perceived general and specific self-efficacy improved as well. Teaching communication skills is important to help nurses cope with a broad range of stressors in their daily interactions with patients, increasing their perceived self-efficacy.
