Strengthening the Link between Vaccine Predispositions and Vaccine Advocacy through Certainty.

BACKGROUND: Instruments designed to assess individual differences in predispositions towards vaccination are useful in predicting vaccination-related outcomes. Despite their importance, there is relatively little evidence regarding the conditions under which these instruments are more predictive. The current research was designed to improve the ability of these kinds of instruments to predict vaccination advocacy by considering the certainty associated with the responses to vaccination scales. METHOD: Across two studies, participants completed the Beliefs about Medicines Questionnaire BMQ scale (Study 1) or the Vaccination Attitudes Examination (VAX) scale (Study 2). The certainty participants had in their responses to each scale was either measured (Study 1) or manipulated (Study 2). Intentions to advocate in favor of vaccination served as the criterion measure in both studies. RESULTS: As expected, the scales significantly predicted vaccination advocacy, contributing to enhancing the predictive validity of the instruments used in the studies. Most relevant, certainty moderated the extent to which these scales predicted vaccination advocacy, with greater consistency between the initial scores and the subsequent advocacy willingness obtained for those with higher certainty. CONCLUSIONS: Certainty can be useful to predict when the relationship between vaccination-related cognitions (i.e., beliefs or attitudes) and advocacy willingness is likely to be stronger.

Validity of the Spanish Version of the Vaccination Attitudes Examination Scale.

Individuals vary in the extent to which they have unfavorable attitudes towards vaccines. The Vaccination Attitudes Examination (VAX) Scale is a recently developed brief 12-item questionnaire created to better understand general vaccination attitudes. The current research aimed at providing a Spanish adaptation of the VAX Scale. After conducting an initial pilot study, Exploratory and Confirmatory Factor Analysis showed that the Spanish version of the scale had good internal consistency and factor structure (Study 1), discriminant validity from other individual differences measures (such as the Beliefs about Medicine Questionnaire and the Medical Mistrust Index) as well as good predictive validity of relevant vaccination-related outcomes (Study 2). In conclusion, in the present research, the Spanish version of the VAX scale proved to have a high internal consistency, showed convergent validity with other conceptually similar constructs, and successfully predicted vaccination intentions and vaccination decisions. Having this scale available in Spanish will allow researchers to analyze vaccination processes and vaccine hesitancy over a great number of people.

The Role of Meta-Cognitive Certainty on Pornography Consumption.

BACKGROUND: The Problematic Pornography Use Scale (PPUS) was originally designed to help predicting pornography consumption. Despite the frequency with which this scale is used in the scientific literature, there is still relatively little evidence regarding the predictive validity of this important instrument. This current research introduces a construct capable of improving the ability of the scale to predict pornography consumption (meta-cognitive certainty). METHOD: Over two studies, participants completed the PPUS and the meta-cognitive certainty in their responses to the scale was measured (Study 1) or manipulated (Study 2). Self-reported porn consumption was the criterion measure in both studies, with an additional actual overt behavior relevant to consumption of porn included in Study 2. RESULTS: As expected, the PPUS significantly predicted porn consumption, confirming the predictive validity of the scale. More importantly, meta-cognitive certainty was capable of moderating the extent to which scores on the PPUS could predict porn consumption, with greater consistency between the PPUS and reported behavior from those with high (vs. low) meta-cognitive certainty. CONCLUSIONS: These data suggest that considering meta-cognitive certainty may be useful for predicting when the link between the PPUS and porn consumption is stronger.

The Neurosciences of Health Communication: An fNIRS Analysis of Prefrontal Cortex and Porn Consumption in Young Women for the Development of Prevention Health Programs.

This work explores the use of fNIRS neuroimaging technique using young female college students with different levels of consumption of pornography, and the activation of the prefrontal cortex (cue reactivity) when viewing a pornographic clip (cue exposure) versus a control clip. The results indicate that the viewing of the pornographic clip (vs. control clip) causes an activation of Brodmann's area 45 of the right hemisphere (BA 45, pars triangularis) (p < 0.01). An effect also appears between the level of self-reported consumption and the activation of right BA 45: the higher the level of self-reported consumption, the greater the activation (p < 0.01). On the other hand, those participants who have never consumed pornographic material do not show activity of the right BA 45 compared to the control clip (p < 0.01) indicating a qualitative difference between non-consumers and consumers. These results are consistent with other research made in the field of addictions. It is hypothesized that the mirror neuron system may be involved, through the mechanism of empathy, which could provoke vicarious eroticism. Finally, we suggest the applications that these results may have for primary and secondary prevention programs in the field of problematic consumption of pornography.
