Manipulating the alpha level cannot cure significance testing

We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple independent studies. When evaluating the strength of the evidence, we should consider, for example, auxiliary assumptions, the strength of the experimental design, and implications for applications. To boil all this down to a binary decision based on a p-value threshold of 0.05, 0.01, 0.005, or anything else, is not acceptable

Bienestar psicológico y salud: Aportaciones desde la Psicología Positiva

Positive Psychology is contributing to a more precise definition of the outline of human well-being and is fully incorporating studies on positive elements (strengths and positive emotions) that are without doubt amplifying the framework of research and conduct of psychology, in particular that of Clinical Psychology and Health Psychology. Over the last few years, academic debate has, from a scientific perspective, gone back to two ancient philosophical orientations, namely hedonism and eudaimonia. The hedonic approach conceives well-being as the presence of positive affect and lack of negative affect, whilst the eudaimonic perspective regards well being as the consequence of a full psychological actualization from which people develop their whole potential. Whether assessed from a hedonic or eudaimonic perspective, well-being seems to play a role in the prevention of and in the recovery of physical conditions and diseases and so possibly contributes to an increase in life expectancy. Finally, the implications of these findings are discussed both from an academic perspective and, more generally speaking, from a social and political point of view

Psychological well-being and health. Contributions of positive psychology

La Psicología Positiva está permitiendo definir con mayor precisión los contornos del bienestar humano y está incorporando de pleno derecho el estudio de elementos positivos (fortalezas, emociones positivas) que sin duda amplían el marco de investigación y actuación de la Psicología y, en particular, en la Psicología Clínica y de la Salud. El debate académico de los últimos años ha venido a reproducir desde una perspectiva científica dos antiguas orientaciones filosóficas: el hedonismo y la eudaimonia. Desde la perspectiva hedónica se entiende el bienestar como la presencia de afecto positivo y la ausencia de afecto negativo, mientras que desde la perspectiva eudaimónica se propone que el bienestar es consecuencia de un funcionamiento psicológico pleno a partir del cual la persona desarrolla todo su potencial. Tanto si es evaluado desde una perspectiva hedónica como eudaimónica, el bienestar parece tener un papel en la prevención y en la recuperación de condiciones y enfermedades físicas, permitiendo posiblemente un incremento en la esperanza de vida. Para finalizar, se discuten las implicaciones de estos hallazgos tanto en un plano académico como, desde un punto de vista más amplio, a nivel social y político
