Unperceived dating violence among Mexican students

The aim of this ex post facto study was to determine the level of self-perceived abuse and the feelings of fear and entrapment that exist among Mexican students in a dating relationship. We intended to explore possible differences in the prevalence of the various types of violence or victimization between individuals who perceive themselves as being abused and those who do not, combining such perceptions with the feelings of fear and entrapment. The sample was composed of 3,495 Mexican students, of which 1,927 were pre-university students (M = 20.16; SD = 2.13) and 1,568 were university students (M = 15.99; SD = 1.64). We applied a questionnaire on socio-demographic data and the Cuestionario de Violencia entre Novios (CUVINO, Dating Violence Questionnaire). Results showed that 88% of participants did not feel abused by their boyfriend or girlfriend; yet, 15.2% reported having been afraid and 27% reported having felt trapped in the relationship at some point. The data revealed that a considerable majority of youth in the sample had been victims of unperceived abuse. More specifically, they presented evidence of having experienced abuse in their dating relationship even when they described themselves as not being abused.     

Long-term outcomes of Acceptance and Commitment Therapy in drug-dependent female inmates: A randomized controlled trial

The general aim of this randomized controlled trial was to test the long-term efficacy of acceptance and commitment therapy (ACT) compared to a cognitive behavioural therapy (CBT) condition in the treatment of drug abuse. Participants were 37 polydrug incarcerated females assessed with Mini International Neuropsychiatric Interview, Addiction Severity Index-6, Anxiety Sensitivity Index (ASI) and Acceptance and Action Questionnaire II at pre, post, and at 6-, 12- and 18-months follow-ups. The mixed lineal model analyses showed reductions in drug abuse, ASI levels and avoidance repertoire in both conditions, without any differences between groups. However, the percentages of mental disorders were reduced only in ACT participants. At the 18-month follow-up, ACT was better than CBT in the maintaining of abstinence rates. This data support the incubation pattern showed in previous ACT studies. To conclude, the ACT intervention seems to be an adequate treatment option for addictive behaviours and co-occurring disorders in incarcerated women.     

Performance evaluation of recent information criteria for selecting multilevel models in Behavioral and Social Sciences

This study was designed to find the best strategy for selecting the correct multilevel model among several alternatives taking into account variables such as intraclass correlation, number of groups (m), group size (n), or others as parameter values and intercept-slope covariance. First, we examine this question in a simulation study and second, to illustrate the behavior of the criteria and to explore the generalizability of the findings, a previously published educational dataset is analyzed. The results showed that none of the selection criteria behaved correctly under all the conditions or was consistently better than the others. The intraclass correlation somewhat affects the performance of all selection criteria, but the extent of this influence is relatively minor compared to sample size, parameter values, and correlation between random effects. A large number of groups appears more important than a large number of individuals per group in selecting the best model (m ≥ 50 and n ≥ 20 is suggested). Finally, model selection tools such as Akaike's Information Criterion (AIC) or the conditional AIC are recommend when it is assumed that random effects are correlated, whereas use of the Schwarz's Bayesian Information Criterion or the consistent AIC are advantageous for uncorrelated random effects.     

Where to look for information when planning scientific research in Psychology: Sources and channels

It is imperative that researchers invest time in the planning of their research, and it is certainly essential to stop and seek information before making any kind of decision. The present work sets out to guide psychologists in this crucial task. To this end we begin by suggesting a visit to the APA website, where a great deal of relevant information on most topics can be found, whether it pertains to new and controversial issues or to those on which there is greater consensus. In this regard we shall consider at length the meanings of the expressions “evidence-based practice” and “scientific evidence” and their inherent methodological aspects, from “scientific evidence” contributed by systematic reviews to the way it can be obtained using handbooks and guidelines of inestimable value for the successful completion of our research. All such resources will help researchers to set out their hypotheses correctly, to test them adequately and to analyze the data in the most appropriate and rigorous fashion. In this way, the quality of the research will undoubtedly improve.     

Validation of the Internet and Social Networking Experiences Questionnaire in Spanish adolescents

The aim of this paper is to validate the Internet Related Experiences Questionnaire (IREQ) with a sample of 525 participants from Compulsory Secondary Education, considering the possible addiction to the internet from both interpersonal and intrapersonal dimensions. Besides, associations between CERI scores and several variables such as sex, age as well as selfesteem were analyzed. Results show a good fit of the questionnaire through a Confirmatory Factor Analysis (CFA), where the interpersonal factor explains a higher percentage of the variance at the expense of the intrapersonal factor. Statistically significant differences between IREQ scores and age and a lineal positive association between self-esteem and possible interpersonal addiction to the internet were found. The possibility of these results to be affected by the social use of the Internet and the generalization in young people's lives is discussed. Moreover, the need of designing and implementing prevention programs for a healthy use of the internet is discussed.     

Standards on how to develop and report systematic reviews in Psychology and Health

Systematic reviews are secondary studies that summarize the best scientific evidence available by means of explicit and rigorous methods to identify, select, appraise, analyse and summarise the empirical studies that enable responding to specific questions. The aim of this theoretical study is to set out a series of standards and recommendations for the planning, development and reporting of a systematic review in the field of the health sciences. The article describes the systematic reviews in the context of practice based on scientific evidence, their rise, justification, applicability and differences compared to traditional literature reviews. Secondly, the methodology is set out for their development and guidelines are established for their preparation; the stages of the process and preparation of a protocol are described with emphasis on the steps to follow to prepare and report a systematic review. Finally, some additional considerations are set out for their preparation and publication in a scientific journal. This guide is aimed both at authors and reviewers of a systematic review.     

Maladaptive personality traits in adolescence: Psychometric properties of the Personality Diagnostic Questionnaire-4+

The Personality Diagnostic Questionnaire-4+ (PDQ-4+) is a self-report used for the assessment of personality disorder traits, however, its psychometric characteristics have yet to be tested in community samples of adolescents. The main goal was to analyze the psychometric properties of the PDQ-4+ scores in a large sample of non-clinical adolescents (N = 1,443; M = 15.9 years; SD = 1.2). The PDQ-4+ scores showed adequate psychometric properties. Reliability of the subscales, incorporating a Likert-type 5-point response format, ranged from .62 to .85. The study of the internal structure at item level revealed that the PDQ-4+ subscales were essentially one-dimensional. Analysis of the internal structure at the subscale level by means of exploratory factor analysis and exploratory structural equation modeling yielded a possible three-dimensional solution. The PDQ-4+ subscales correlated moderately with emotional and behavioural variables measured by the Strengths and Difficulties Questionnaire. The results have clear implications for the understanding of maladaptive personality traits in adolescents.     

Attention Deficit Hyperactivity Disorder,differential diagnosis with blood oxygenation,beta/theta ratio,and attention measures

Attention Deficit Hyperactivity Disorder (ADHD) is one of the disorders causing the greatest impact, conditioning academic learning, quality of concentration, and capacity for self-regulation and control. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV-TR) establishes the most commonly accepted criteria for diagnosis (Inattentive: ADHD-I, Hyperactive/impulsive: ADHD-HI, and Combined: ADHD-C), but currently, diverse studies disagree about whether to address it as a continuum with different degrees of intensity (subtype structure) or as specific disorders (counterposed profiles). Prior research has tested the hypothesis of differential categories with performance measures and cortical activation. The goal proposed herein is to confirm these results, incorporating a new measure, near-infrared hemoencefalography (nir-HEG), in order to control cortical activation through levels of blood oxygenation. For this purpose, we used a sample of 205 children between 8 and 13 years (105 control group, 28 with ADHD-I, 35 with ADHD-HI, and 37 with ADHD-C), administering a continuous performance test (TOVA), quantified electroencephalogram (Q-EEG), and nir-HEG. Results reflect the counterposed profiles hypothesis instead of the degrees of intensity, although the latter is more habitual and generalized.     

Socio-demographic and psychopathological risk factors in obsessive-compulsive disorder: Epidemiologic study of school population

We assessed the presence of emotional disorders (obsessive-compulsive, anxiety and depressive) in 1,514 Spanish non-referred children (8–12 years old) to investigate the predictive ability of psychopathological and socio-demographic characteristics, and identify which of these were possible correlates for clinical obsessive-compulsive disorder (OCD) and subclinical OCD. At one year later, 562 subjects (risk group and without risk group) were re-assessed and we established the OCD diagnoses or the subclinical OCD diagnoses. We found that 20 participants presented clinical OCD and 46 participants presented subclinical OCD. Somatic and separation anxiety symptomatology were good predictors for clinical OCD, and obsessive concern was a predictor for subclinical OCD. Clinical OCD was associated with order/checking/pollution symptoms and with a lower socioeconomic status (SES). Subclinical OCD was associated with hyperactive and impulsive manifestations, obsessive concern, and superstition/mental compulsion. An early detection and the follow-up of anxiety or obsessive symptoms in children may be important for preventing the course of OCD.     

Reporting a program evaluation: Needs,program plan,intervention, and decisions

The approach to intervention programs varies depending on the methodological perspective adopted. This means that health professionals lack clear guidelines regarding how best to proceed, and it hinders the accumulation of knowledge. The aim of this paper is to set out the essential and common aspects that should be included in any program evaluation report, thereby providing a useful guide for the professional regardless of the procedural approach used. Furthermore, the paper seeks to integrate the different methodologies and illustrate their complementarity, this being a key aspect in terms of real intervention contexts, which are constantly changing. The aspects to be included are presented in relation to the main stages of the evaluation process: needs, objectives and design (prior to the intervention), implementation (during the intervention), and outcomes (after the intervention). For each of these stages the paper describes the elements on which decisions should be based, highlighting the role of empirical evidence gathered through the application of instruments to defined samples and according to a given procedure.
