I'm Dolores Frías-Navarro, Associate Professor
of Psychology at the University of Valencia (Spain). Department
of Methodology of the Behavioural Sciences. I am also a Professor in Statistics and Design and Research Methods.
I am Director of Psychology Research Unit Design in Applied
Psychology, which is devoted to the advancement and
dissemination of statistical methodology related to research in Psychology.
My research focuses on the development, improvement, and evaluation of
quantitative methods, especially as they relate to statistical issues in applied
research, with an emphasis on the design of research studies. Specific areas of
investigation include the effects of heteroscedasticity
on inference and statistical approaches to assessing mediation.
My research tasks include topics related with the importance of
considering effect size and statistical power in research and Evidence-Based
Practice in Psychology (PBE). Evidence-based practice in psychology has
been defined as the “integration of the best available research with clinical
expertise in the context of patient characteristics, culture, and preferences”
(Am. Psychol. Assoc. Presid. Task
Force on Evidence-Based Pract. 2006, p. 273).
I'm very interesting in the advancement and dissemination of statistical
methodology related to research in Psychology. In addition, I have adapted into
Spanish the CONSORT 2010 (Schulz, Altman, Moher,
& CONSORT group, 2010). Is in: https://www.uv.es/friasnav/CONSORTSpanish.pdf
I have participated in research funded by the Ministry of Education in
Spain. Project: “Estimating effects: uses and abuses of hypothesis testing in
Psychology” (2001-2004) and “Critical revision of the statistical design in
Psychology” (2004-2007) and “Statistical reform in Psychology and Education” (2011-2014).
Although my research is methodological, I enjoy working with substantive
researchers in mutually beneficial collaborations, where I can develop needed
or apply existing methods to address interesting and important real-world
problems. As Tukey
pointed out, “the best
thing about being a statistician is that you get to play in everyone’s backyard!”
I teach courses at the graduate and undergraduate level on research
design and data analysis.

about children’s adjustment in same-sex families in a sample of Spanish and
Chilean University students. Submitted.
The main purpose of our study is to compare the
beliefs of Spanish and Chilean university students about the effects that
same-sex parents can have on their children. A total of 491 participants
completed the study (208 Spaniards and 283 Chileans). The results indicate a
kind of modern and subtle rejection based on hetero-normativity.
Furthermore, the results indicate the effects of sex (men have a greater
degree of rejection), traditional and sexist opinions linked to a greater
rejection of same-sex parents, and the contact variable, which inversely
correlates with this rejection. The results show that the etiology of
homosexual orientation also correlates with rejection of same-sex parents
when it is believed that homosexuality is learned or can be changed. 2012. Frías-Navarro,
D., & Monterde-i-Bort, H. (2012). Scale
of Beliefs about Children’s Adjustment in Same-Sex Families: reliability and
validity. Accepted for publication.
The authors developed a Scale of Beliefs about
Children’s Adjustment in Same-Sex Families (SBCSSF).
The scale was developed to assess of the adults’ beliefs about negative
impacts on children who are raised in same sex parents. An initial pool of 95
items was generated by the authors based on a review of the literature on homophobia
and feedback from several focus groups. Research findings, based on a sample
of 212 university students (mean age 22 years, SD = 8.28),
supported the reliability and validity of the scale. The final versions of
the SBCSSF included items reflecting the following
two factors: Individual Opposition (Cronbach’s
alpha = 0.87) and Normative Opposition (Cronbach’s
alpha = 0.88). Convergent validity of the scale is demonstrated by
predictable correlations with beliefs about the cause of homosexuality and
the support for homosexual rights. Our study reveals a strong positive
association between high scores on the Scale of Beliefs about Children’s
Adjustment in Same-Sex Families and beliefs that the origin of homosexuality
is learned and opposition to homosexual rights. 2012. Frías-Navarro,

controlled trials. 19Cochrane Colloquium. Madrid, 19-22 of October de 2011. Poster
Background: Randomized controlled trials (RCTs) are the gold standard for trials assessing the
effects of therapeutic interventions and provide the best evidence to inform
and guide clinical decision-making. Therefore it is important to understand
how they are conducted and how to evaluate the strength of evidence. Bias is
a systematic tendency to produce an outcome that differs from the underlying
truth. Bias in clinical trials falls into four categories: selection bias,
performance bias, detection bias and attrition bias. There are numerous tools
to assess methodological quality of primary studies. Understanding the
relationship between the risk of bias and the effect size can help plan
research to monitor the presence of such bias. Objectives: Our work has three
objectives. First, provide an analysis of the relationship between bias and
effect size. Second, analyze the bias and reporting checklists (example
CONSORT). Third, we review and analyze the Cochrane Collaboration’s tool for
assessing risk of bias. Methods: Systematic review. Results: The
methodological quality of studies can have a substantial impact on estimates
of treatment effect, which may affect the validity of the conclusions Conclusions: Our work helps to identify areas of strength
and weakness in the existing evidence and to formulate recommendations to
improve the conduct and value of future research. 2011. Badenes-Ribera, L., Leopold

Emotions as
variables involved in the relationship between prejudice towards immigrants
and contact. Affective and emotional factors play a
significant role in the study of relations between groups and, specifically,
the analysis of the predictors of prejudice. The main purpose of our research
is to understand the emotions aroused by immigrants and relationship to both
blatant and subtle prejudice. Therefore, a non-experimental research has been
carried out with a sample of university students. In our research, first
examines the relationships of emotions to the prejudice against immigrants,
considering the differences between egalitarian, subtle and fanatical
subjects. Secondly, the role of emotions (positives, negatives, subtle
positives and subtle negatives) is investigated in a measuring model as
variables that intervene in the connection between the variable of contact
with immigrants and blatant or subtle prejudice. Our findings indicate the
importance of emotions in intergroup relations, operating as measuring
variables between the level of contact with immigrants and the level of
prejudice (blatant and subtle). Thus, we present evidence supporting the
theory of the Intergroup Emotions. 2011. Badenes-Ribera, L., Leopold Escolano,

manifiesto y sutil hacia los inmigrantes y los padres del mismo sexo a través
del contacto inter-grupo. V Congreso Nacional de
Estudiantes de Psicología. Valencia, 11 al 13 de Abril, 2011.
Reduce the blatant and subtle prejudice
toward immigrants and same-sex parents through the inter-group contact. Prejudice as an
expression of negative affective response leads to rejection of the
individual who does belong to the in-group. In democratic societies like
ours, blatant prejudice is clearly decreasing and has been replaced by a more
subtle or covert form of discrimination. The effect of inter-group contact
has been documented in literature as a mechanism to reduce prejudice. The
sample of our research consists of 207 psychology students. The purpose of
this non-experimental research is threefold. On the one hand, to check and
analyze the connection between blatant and subtle prejudice towards
immigrants and the belief about the psychological wellbeing of children
raised by same-sex parents. On the other hand, we analyze the differences
between men and women in the manifestation of such prejudice. Also, we
studied the role of intergroup contact as an element that reduces
discrimination. The findings indicated that there is a statistically
significant relationship between blatant and subtle prejudice toward
immigrants and beliefs about the psychological adjustment of children raised
by same-sex parents. Also there are difference scores between men and women
in the two measuring instruments. As well, the results show that contact
between groups is associated with lower levels of prejudice. The results of
our research emphasizes need to develop measuring instruments adapted to the
modern expressions of prejudice. 2011. Frías-Navarro,

Design, quality and bias of reports of randomized experiments.The accurate presentation of
research results is key to the advancement of
knowledge and dissemination of findings. However, not always done correctly.
The movement of Evidence-Based Practice (EBP)
emphasizes the importance of applying the best evidence or the best evidence
from the scientific method for clinical decisions. The experimental
methodology is regarded as the highest quality research and control of bias.
However, the quality of the implementation of the method is really important
and not the method itself. Our research aims to analyze the major scales or
checklists of the design process of experimental research in the area of
health. Our goal is to highlight the elements that require a thorough check
by the researcher to eliminate possible bias in the estimation of treatment
effects. The impact of the recommendations of the CONSORT statement to
randomized clinical trials has led to the production of checklists for a wide
range of problems or needs understanding. Improving the quality of the
research process and presentation of the research report are issues necessary
to ensure the validity of the findings. Critical reading of the sections of
'Method' and 'Results' is key in determining the
quality of evidence or evidence from the investigation report. Emphasize the
importance of the difference between statistical significance, clinical
significance and significance of the effect size is an issue that the
checklists have not highlighted as key elements linked to the quality of the
report. 2011. Pascual

Is
the perception of health condition a good predictor of the overall life
satisfaction? The goal of
this paper is build up a model that allow us predict the satisfaction the
people have with their own lives in general. As an starting point, we set as
independent variables, the evaluation, of the people that are part of the
sample, do about the issues referred to work, family relations, income, free
time availability, friends, couple relations and health. The identification
of the regression model will allow us to observe whether the satisfaction
with health, to the extent that increasing age, is a statistically
significant variable, and, if so, adequate to predict overall satisfaction.
The source of the analysis is the data of the September 2010 barometer of the
CIS (Sociological Research Center). Thus we will work with a random sample of
2.473 people, representative of the Spanish population over 18 years old.

and other statistical resources: a comparative study. European Journal of Psychology of Education,

The empirical study we present here deals with a pedagogical issue
that has not been thoroughly explored up until now in our field. Previous
empirical studies in other sectors have identified the opinions of
researchers about this topic, showing that completely unacceptable
interpretations have been made of significance tests and other statistical
resources. We tried to show the degree to which these errors of
interpretation appear in a sample of university professors and researchers.
To evaluate the beliefs and opinions of the university professors about
certain methodological and statistical questions, we adapted the
"Psychometrics Group Instrument" questionnaire by Mittag (1999) and Mittag and
Thompson (Educational Researcher 29:14-20, 2000). We specifically wanted to
detect opinions about: (1) avoiding inappropriate interpretations, (2)
rectifying incorrect uses, (3) creating a debate on possible alternatives,
and (4) proposing editorial changes in the publication criteria. In this
study, we compare the results we obtained with those obtained by two other
equivalent studies (Gordon, Journal of Vocational Educational Research
26:1-18, 2001; Mittag and Thompson, Educational
Researcher 29:14-20, 2000). The characteristics of the sample and the scope
of the results are described, and a critical reflection is carried out on
typical misunderstandings in interpretation that show a worrisome lack of
understanding of some basic methodological and statistical concepts. 2010. Frías-Navarro, D., Pascual M., Monterde i Bort, H., Pascual, J. y Badenes L. (2010). “Puentes y barreras en la elaboración de materials OCW. Encuesta de

Open Course Ware. Open educational resources are growing in the
world. And the Open Course Ware is one of them. The Open Course Ware (OCW) movement in general aims to extend course materials
to learners regardless of their enrollment in a university. Amongst these
institutions, most well-known program is Massachusetts Institute of
Technology’s Open Course Ware (MIT).The OCW is
dedicated to the development of freely available teaching materials in
Internet. Open Course Ware is seen as a model for university dissemination of
knowledge in the Internet age. Reputation and status are vital parts of the
institutional motivation, but also of importance on the individual level of a
professor. This research examines the views of the professors on incentives
and disincentives for the development of materials Open Course Ware (OCW). A survey instrument was developed: "Bridges
and barriers in the development of OCW materials. Survey" (Frías-Navarro, Pascual, Monterde, Pascual y Badenes, 2010).

Are Women More
Empathetic than Men? A Longitudinal Study in Adolescence. Since the 1970s there has been a growing interest in analysing sex differences in psychological variables.
Empirical studies and meta- analyses have contributed evidence on the
differences between male and female individuals. More recently, the gender
similarities hypothesis has supported the similarity of men and women in most
psychological variables. This study contributes information on women’s
greater empathic disposition in comparison with men by means of a
longitudinal design in an adolescent population. 505 male and female
adolescents aged between 13 and 16 years were evaluated at two different
moments (grade 2 and grade 3, lower secondary education). They completed the
Index of Empathy for Children and Adolescents by Bryant and the Interpersonal
Reactivity Index by Davis. The results confirm a greater empathic response in
females than in males of the same age, differences growing with age. The
sizes of the effect estimated in the second evaluation (average age 14 years)
are large for emotional empathy and medium for cognitive empathy.

La
enseñanza de la metodología de investigación con analogías. La analogía es una herramienta cognitiva muy útil para facilitar el
descubrimiento y el aprendizaje de nuevos conceptos a través del conocimiento
que ya posee el sujeto. En nuestro trabajo se utiliza la analogía para la
enseñanza del proceso de decisión estadística y los errores estadísticos
(error de Tipo I y error de Tipo II) desde la perspectiva del pensamiento
analógico. El uso de la analogía es una estrategia que permite facilitar la
presentación y enseñanza de cuestiones que son percibidas por los estudiantes
con ciertas expectativas negativas que dificultan desde el comienzo el
proceso de Enseñanza-Aprendizaje. Uno de los aspectos más difíciles de la
enseñanza de la metodología y el proceso de diseño de investigación es
motivar a los alumnos para que desarrollen un pensamiento estadístico.
Conceptos como hipótesis nula, hipótesis alternativa, intervalos de
confianza, prueba estadística o distribuciones de muestreo son abstracciones
para los estudiantes que no logran integrar en su formación académica. El
objetivo de nuestro trabajo es trabajar las cuestiones del contraste de
hipótesis estadísticas con la analogía del proceso de un juicio donde la
presunción de inocencia se vincula con la verdad de la hipótesis nula como
inicio del proceso de decisión estadística. 2009. Frías-Navarro, D., Monterde-i-Bort,

2009. Febrero.
La medida del prejuicio manifiesto y sutil. La medida del
prejuicio resulta especialmente difícil desde la perspectiva del prejuicio
manifiesto tradicional dada su baja aceptación social. Los investigadores
sugieren que actualmente existe una nueva forma de expresión del prejuicio
más sutil que ha reemplazado a otras formas más agresivas de prejuicio. En
nuestro trabajo nos centramos en la investigación europea de Pettigrew y Meertens (1995,
1997). Pettigrew y Meertens
(1995) diferencian entre dos tipos de individuos con prejuicio; racistas
manifiestos y racistas sutiles y sugieren que ambos tipos de prejuicio puede
ser medido fiablemente de forma separada. En nuestro trabajo se presenta
evidencia sobre la estructura y dimensiones de “Blatant
and Subtle Prejudice Scale”; y examinamos si esas dos formas de prejuicio
se pueden distinguir en una muestra de estudiantes de Psicología de la
Universidad de Valencia (España). También se midió la deseabilidad social con
la escala “Marlowe Crowne’
Social Desirability Scale”.

intervals of means. In this
study, we analyzed the validity of the conventional 80% power. The minimal
sample size and power needed to guarantee non-overlapping (1 - a)% confidence intervals for population means were
calculated. Several simulations indicate that the minimal power for two means
(m= 2) to have non-overlapping CIs is .80, for (1 - a) set to 95%. The
minimal power becomes .86 for 99% CIs and .75 for 90% CIs. When multiple
means are considered, the required minimal power increases considerably. This
increase is even higher when the population means do not increase
monotonically. Therefore, the often adopted criterion of a minimal power
equal to .80 is not always adequate. Hence, to guarantee that the limits of
the CIs do not overlap, most situations require a direct calculation of the
minimum number of observations that should enter in a study. 2008.

assignment has the aim of going deeply into the study of service quality
perception in supermarkets. The research tries to find the criterion used when
rating the services received in a supermarket and also to elaborate an
instrument to measure the service quality in this context. From the review of
the existing bibliography, four theoretical factors and a thirteen items
scale have been composed. These four factors are: price, product, service and
image and fresh product. In order to check the psychometrical properties of
the questionnaire we carried out a computer assisted telephone interviewing
(CATI) with a sample of 300 interviews. The results obtained allow us to show
a scale with a factorial structure of 4 dimensions that throws up optimal
indexes of reliability and validity. At the same time we conclude that the
variable called establishment global rate is an important variable in the
perceptive structure of the consumers. |

emotional processes reach higher correlation with aggressive behaviour,
emotional instability and proneness to anger being the main predicting
factors of aggressiveness, while empathy appears like the main predictor of prosocial behaviour. The parents’ child-rearing styles
have a secondary position in drawing the differential profile between high
and low prosocial proneness, behind personal
variables and are moved by emotional processes in prediction of aggressive
behaviour. |

Index. The main aim of this study was to analyze the psychometric properties
of the Interpersonal Reactivity Index (IRI) (Davis, 1980, 1983) in its
Spanish adaptation. It is one of the questionnaires but used to evaluate the
empathy from a multidimensional perspective that includes two cognitive
factors and two emotional. The Spanish adaptation has been carried out with a
wide sample of fellows belonging to different educational centers
of the Valencian Community (1.285 adolescents, 698
males and 597 women, with an age range between 13 and 18 years). The results
of this study indicate the validity of the instrument to evaluate the
different components of the empathy.

BASADA EN PRUEBAS: EFECTO DEL TRATAMIENTO. Dolores Frías-Navarro y Juan Pascual Llobell Papeles del Psicólogo, 85, 2003 The practice of Evidence-Based Clinical
Psychology means integrating individual clinical expertise with the best
available external clinical evidence from systematic research. Evidence-Based
Psychology (EBP) is an approach that promotes the collection, interpretation,
and integration of valid, important and applicable patient-reported,
clinician-observed, and research-derived evidence. It is dependent on the use
of randomised controlled trials, as well as systematic reviews of a series of
trials and meta-analysis, although it is not restricted to these. Evidence-Based
Psychology follows four steps: formulate a clear clinical question from a
patient’s problem; search the literature for relevant clinical articles;
evaluate (critically appraise) the evidence for its validity and usefulness;
implement useful findings in clinical practice. [ |

factors of aggressive behaviour. The purpose of this paper is to analyze
personality and family variables related to adolescent aggressiveness,
emphasis being placed on emotional processes linked to a lack of control or
emotional regulation and child-rearing styles perceived in their parents by
adolescents. An empirical analysis was carried out including 1,285 randomly
selected youngsters (aged 13 to 18, 698 males and 597 females). The
discriminating analyses conducted show that emotional processes reach higher
correlation with aggressive behavior, emotional
instability and proneness to anger being the main predicting factors of

pro-social behaviour and aggressive conduct: empathy as a modulating factor. The objective of this research is to
review some cognitive and emotional processes that regulate pro-social
behaviour and aggressive conduct in adolescence, emphasis being placed on empathic
processes. An empirical study has been carried out including 1,285 randomly
selected adolescents (aged 13-18, 698 male / 597 female). The discriminating
analyses conducted point out that emotional processes reach higher
correlation with aggressive conduct and pro-social behaviour, emotional
instability standing out as the main aggressiveness predictor, and
non-impulsive, ‘positive’ and empathic emotionality as the best predictor for
pro-social behaviour. On the contrary, pro-social reasoning processes
followed by adolescents in opting for a given help conduct are less relevant
to the prediction of such behaviours. [ |

deduced by low statistical power. The goal of this article is to examine the

measurement scale is discrete. The aim of this research is to examine the influence of sample size
on the statistical validity of experimental designs (i.e. assuming random
assignment and direct manipulation) when the dependent variable is discrete
and measured in an ordinal scale, which is distributed as a rectangular
distribution -any point of the sample space is equally likely. The dependent
variables in the psychological studies always are not continuous and, even in
this case, frequently, it is difficult to guaranteed
the normality assumption. In this paper we constructed a sample distribution
of the F statistic for the ordinal and discrete scale, and we compare
this distribution which the classical distributions which assume that the
dependent variable is normally distributed. |

of the data. This paper analyses
the relationship between the concepts of statistical significance (level of
probability, p) and replicability. The level of
statistical significance (for example, p = 0.01) indicates the probability of
the data under the null hypothesis assumption, however, this does not mean
that in a later replication the probability to obtain significant differences
will be the complementary, 0.99. If correctly understood, replicability
is exclusively related to the reliability and consistency of the data. The only
way to evaluate reliability is through repeated empirical tests. [ |

has a number of well-known logical fallacies and the results of the
procedures are often misinterpreted. Many scholars have suggested that,
perhaps, NHST should be abandoned altogether in favour of other bases for conclusions
such as confidence intervals and effect size estimates. Other researchers are
often interested in testing the hypothesis that the effects of treatments,
interventions, etc. are negligibly small rather than testing the hypothesis
that treatments have no effects whatsoever. |

DF, Llobell JP Statistical power of Solomon design. This article describes
the use and statistical treatment of the Solomon Four Experimental Design.
Campbell and Stanley (1963) noted "the Solomon Four Experimental Design
has higher prestige and represent the first explicit consideration of
external validity factors". Broad applicability of the Solomon Four
Experimental Design has been limited in research (Braver y Braver, 1988).
Perhaps the most important reason why the Solomon design is underused is the
lack of certainty concerning the proper statistical treatment of this rather
complicated design. Braver & Braver (1988) proposed a meta-analysis
approach to test the efficacy of an intervention in the Solomon Four Design.
In their article Braver and Braver provide a rationale for the sequence of
decisions at each point in the algorithm, but make no attempt to estimate the
effect of sequential tests on the experiment-wise error rates. |

cognitive adjustment in abused children. Research on the
impact of maltreatment on children has increased in the last years, as there
is a need to design appropriate treatment strategies. Social, cognitive, and
emotional areas may be affected in these children. This research is aimed to
study the psychological functioning of child victims, particularly in their
emotional and cognitive adjustment. Nineteen children (10.3 years old) with
case histories of at least 2 years of physical and emotional parental abuse
and a group of 26 no maltreated children (9.4 years old) matched in
socio-economic characteristics and coming from the same community area were
compared in depressive symptomatology and attributional style by using the standardized measures
from Kovacs' Children's Depression Inventory (CDI) and Kaslow's
Children Attributional Style Questionnaire (CASQ).
General and detailed statistical analyses on the emotional and cognitive
areas assessed showed significant differences between groups. Child victims
showed greater feelings of sadness, lower self-esteem and self- worth, and
they perceived the aversive events in their lives as unpredictable which
generated helplessness. This is a result of their lack of control of those
aversive events. Results are contrasted with those obtained by other
researchers who used similar methodology and are discussed in terms of the
learned helplessness' model proposed and developed by Seligman, Kaslow, Alloy, Peterson, Tanenbaum,
and Abramson (1984). Implications for the child abuse victims' emotional and
cognitive rehabilitation are also analyzed and discussed. [ 1992. ESTRUCTURA FAMILIAR
