The current study seeks to analyze the relationship between learning approaches, self-regulation and performance. Data are gathered from three public European universities, one from the UK (University of Wales Institute, Cardiff) and two from Spain (Universities of Almeria and Granada). Two self-report measurements were used to collect information, the R-SPQ-2F questionnaire and the IATLP Scales. Results indicate that learning approaches are related to self-regulation and to academic performance. Different relationships with learning approaches are obtained depending on the type of performance analyzed (conceptual, procedural, attitudinal), which may account for divergent conclusions in other research studies. New lines of research are proposed based on the conclusions.  相似文献

Although online psychological services and research based on them are increasing rapidly, it is not that easy to find investigations that focus on the kind of people that demand them. To know their profile could help to improve the online psychological services that are offered to them. For this purpose, we analysed the sociodemographic characteristics of 1052 participants, all of them having posed a psychological question to our online advice service. The relations between sociodemographics and variables related to the psychological consultation are analysed herein. Features such as age distribution, a high proportion of long-term problems, the large quantity of questions from Latin America, or the under representation of the lowest socioeconomic and educational levels could lead to clinical, social and legal implications that we comment on in this work.  相似文献

This paper presents the theoretical and methodological basis of a therapist's verbal behavior category system that allows us to study clinical psychologists' language from a functional-analytic framework and with a rigorous observation method. The procedure to develop the coding system is explained in detail from a very early stage of exploratory observation, to the systematic observation through the use of The Observer XT software. An analysis of intra- and inter-rater reliability using the kappa coefficient and taking into account the factors that affect the values of Cohen's index was carried out. Results show high levels of observer accuracy (between approximately 87% and 93%) that justify the application of this category system to study therapists' verbal behavior in session.  相似文献

Based on a systematic review of some 23 (out of 300 originally located) studies, it is concluded that most studies show lower rates of re-offending following a non-custodial compared to a custodial sanction. However, this outcome may be biased because, in most quasi-experiments of this kind, subjects with the worst prospects of rehabilitation are likely to be sent to prison. In a meta-analysis limited to five randomised controlled trials and one natural experiment, it is concluded that custodial and non-custodial sanctions do not differ significantly in terms of re-offending. Lessons from this review include, in view of future evaluations, the need to increase randomised controlled trials, to use broader measures of re-offending and rehabilitation, to look at long-term effects, and to deal with possible Hawthorn effects. Equal rates of re-offending do not mean that or , but that criminal justice policies should not be based on the belief that short-term confinement will be damaging.  相似文献

The article reports a systematic review of controlled outcome evaluations of psychosocial and organic sexual offender treatment. A comprehensive search of the literature in five languages revealed 80 independent comparisons between treated and untreated groups of sexual offenders ( N = 22,181). The majority of studies confirmed a positive treatment effect. Overall, 11.1% of treated offenders and 17.5% of controls showed sexual recidivism (37% difference). Findings for violent and general recidivism were similar. Studies on surgical castration showed the strongest effect; however, this was confounded with methodological and offender characteristics. Hormonal medication, cognitive-behavioural, and behavioural approaches also revealed a positive effect. Non-behavioural treatments did not show a significant impact. Other moderators such as small sample size, authors' affiliation with the program, program completion versus dropout, or type of outcome measure had a significant impact. Methodological study characteristics explained the largest proportion of effect size variance. Overall, findings are promising but more differentiated evaluations of high quality are needed.  相似文献

This paper introduces a new section of Psicothema dedicated to the evidence-based approach to crime prevention. Along with an original sexual-offender-treatment programme implemented in Spain, this section presents four systematic reviews of important subjects in the criminological arena, such as sexual offender treatment, the well-known programme, the effectiveness of custodial versus non-custodial sanctions in reoffending and the fight against terrorism. We also highlight some of the focal points that scientists, practitioners and governments should take into account in order to support this evidence-based viewpoint of crime prevention.  相似文献

The aim of the study was to analyze the consequences of Child Sexual Abuse (CSA) on the psychological adjustment of university students, as well as the way in which several avoidance and approach coping strategies affect that adjustment. The sample comprised 1162 students from the University of Granada. Data about CSA was obtained from a questionnaire developed with this aim. We used the How I Deal with Things Scale of Burt and Katz to evaluate coping strategies, whereas depression and self-esteem were assessed with the Beck Depression Inventory and the Rosenberg Self-Esteem Scale, respectively. Subjects who were victims of CSA showed significantly higher scores on depression and lower scores on self-esteem. An analysis of coping strategies revealed that only the use of avoidance strategies was related to psychological adjustment. Subjects who used these strategies obtained higher scores on depression and lower scores on self-esteem. These results confirm the idea of CSA as a risk experience that can affect victims' psychological adjustment, to a greater or lesser extent, according to the coping strategy employed.  相似文献

Taking into account the studies about the measure of sensitivity in magnitude estimation tasks, we analyze the three most common measures used in this topic: Pearson's product-moment correlation between the logarithm of the stimulus and the logarithm of the response (R), the exponent of Stevens' power function (K), and the measure "M" proposed by Garriga-Trillo. Using a sample of participants greater than usual in psychophysical studies (180 participants), we designed an experiment with two sets of stimuli with different stimulus ranges. In each of these sets, we used two kinds of stimuli (line segments and squares). Our conclusions were: (1) we rejected the use of K as a sensitivity measure because the results provided by this index were the opposite of those expected when we compared the two stimulus ranges. (2) We also rejected the use of M because this measure is a linear transformation of Kendall's coefficient of concordance. (3) Lastly, we suggest the mathematical transformation proposed by Fisher to achieve a normal distribution, and recommend this transformation as the best sensitivity measure.  相似文献

Transplantation may imply severe biopsychosocial impairments. In order to know the quality of life of patients one year after transplantation, 58 subjects were compared to three different groups of patients (stabilized and acute COPD patients, and lung cancer patients in a surgery unit). Patients filled in two questionnaires: EORTC QLQ-C30 (quality of life) and HAD (anxiety and depression). The quality of life dimensions with inter-group differences were physical, role, emotional and cognitive functioning, global health status, and a number of symptoms (fatigue, dyspnea, insomnia and appetite loss). There were differences in depression, and but not in anxiety. Transplant and surgical patients showed better quality of life and affective status than chronic pulmonary patients. Discriminant analysis showed that the transplant group was the best described group. We conclude that patients, one year after transplantation, show similar quality of life as asymptomatic hospitalised patients, somewhat better than chronic patients in a stabilized stage of the disease, and much better than severe chronic patients.  相似文献

Theory provides a helpful basis for designing interventions to change behaviour but offers little guidance on how to do this. This paper aims to illustrate methods for developing an extensive list of behaviour change techniques (with definitions) and for linking techniques to theoretical constructs. A list of techniques and definitions was generated from techniques published in two systematic reviews, supplemented by "brainstorming" and a systematic search of nine textbooks used in training applied psychologists. Inter-rater reliability of extracting the techniques and definitions from the textbooks was assessed. Four experts judged which techniques would be effective in changing 11 theoretical constructs associated with behaviour change. Thirty-five techniques identified in the reviews were extended to 53 by brainstorming and to 137 by consulting textbooks. Agreement for the 53 definitions was 74.7 per cent (15.4% cells completed and 59.3% cells empty for both raters). Agreement about the link between the 35 techniques and theoretical constructs was 71.7 per cent of 385 judgments (12.2% agreement that effective and 59.5% agreement that not effective). This preliminary work demonstrates the possibility of developing a comprehensive, reliable taxonomy of techniques linked to theory. Further refinement is needed to eliminate redundancies, resolve uncertainties, and complete technique definitions.  相似文献
