Factor Structure of the Beck Depression Inventory—II in a Medical Outpatient Sample

This study examined the factor structure of the Beck Depression Inventory—II (BDI-II) in a sample of 127 individuals referred by their primary care physicians. Using exploratory factor analysis with oblique rotation, a 2-factor model appeared to be the most parsimonious representation of the data. The rotated factors accounted for approximately 53% of the variance. Consistent with previous research, the first factor was interpreted as a somatic–affective dimension and the second factor reflected a cognitive dimension. The correlation between these 2 factors was .79. It appears possible to divide the BDI-II into subscales to facilitate interpretation in medical patients.     

Parent‐administered modified dry‐bed training for childhood nocturnal enuresis: evidence for superiority over urine‐alarm conditioning when delivery factors are controlled

We compared the relative efficacy of modified dry‐bed training and standard urine‐alarm conditioning for treating functional nocturnal enuresis in 36 children aged 7–12 years attending health centres in Glasgow, Scotland. A minimal intervention, self‐help approach was adopted. Parents and children received standardized instruction, which, for each method, consisted of one clinic interview and a manual and videotape for home viewing. Outcomes were contrasted with those from untreated controls. Twelve children were randomly assigned to each condition. All groups were matched for age, gender, social class (deprivation category), and baseline wetting frequency. In the two treated groups, an intake interview was followed by two review appointments, otherwise families carried out the programmes independently at home with fortnightly telephone support either until the success criterion of 14 consecutive dry nights was met or the 16 week maximum treatment period expired. Of the 12 children treated by dry‐bed training, eight achieved initial success compared with only three of the 12 treated by the conventional urine‐alarm method. One waiting‐list control child remitted spontaneously. ANOVA showed highly significant differences in wet nights per week immediately after intervention for both treatment and time factors (p < 0.001) and their interaction (p < 0.01). The dry‐bed group averaged 0.8 nights per week wet on treatment cessation, a frequency which was significantly superior to the average of 3.25 for the urine‐alarm group and 5.00 for the controls. Six months after attaining initial success, one child in each treated group had relapsed. Our results show an outcome of 58% long‐term remission (67% initial arrest, 13% relapse) for dry‐bed training when delivered by minimal intervention methods and indicate dry‐bed training as being more effective than orthodox urine‐alarm conditioning for the same input of clinic time and instruction.

Dangerous sports and recreational drug‐use: rationalizing and contextualizing risk

This article reports upon the Interpretative Phenomenological Analysis (IPA) of a small number of semi‐structured interviews, conducted with persons engaging in either recreational drug‐use (primarily identified here as Ecstasy‐users) or dangerous sports (primarily identified here as bungee‐jumpers). Our analysis focuses upon the manner in which these participants make sense of their initiation and maintenance experiences, and the means by which they understand and make sense of risk. In particular, we draw attention to the distinctions between our participants' rational and contextual reconstructions of risky decisions. These distinctions indicate that our participants are able to draw upon a complex cultural and relational understanding of risk and pleasure, and are thus able to deal quite effectively with the contradictory experience of taking ‘non‐volitional’ action. This exploration of persons' strategies for displacing agency in relation to potentially negative outcomes may have implications for research and practice in related areas.

Obsessive and harmonious passion in physically active Spanish and Hungarian men and women: A brief report on cultural and gender differences

Increased research on passion in exercise calls for direct examination of possible moderating variables, such as culture and gender, that could influence the interpretation of the research results. This study using a nation by gender between‐participants design, examined differences in obsessive‐ and harmonious passion in Spanish and Hungarian physically active individuals. Participants (n = 1002) completed the Passion Scale, reported their gender, age and weekly hours of physical activity. Multivariate analysis of covariance revealed that the experiencing of physical activity‐related obsessive‐ and harmonious passion differed between the 2 countries and Hungarian women scored significantly higher on harmonious and obsessive passion than Spanish women. However, Hungarian men only scored significantly higher on obsessive passion, but not harmonious passion compared to Spanish men. These results suggest that gender and cultural differences are likely to affect the interpretation and generalisation of research on passion and exercise.     

Prevalence of pathological Internet use among university students and correlations with self-esteem, the General Health Questionnaire (GHQ), and disinhibition.

Over the last few years, there has been increased interest in the addictive potential of the Internet. The current study was an attempt to replicate common findings in the literature and provide more evidence for the existence of Internet addiction among students--a population considered to be especially vulnerable. A total of 371 British students responded to the questionnaire, which included the Pathological Internet Use (PIU) scale, the General Health Questionnaire (GHQ-12), a self-esteem scale, and two measures of disinhibition. Results showed that 18.3% of the sample were considered to be pathological Internet users, whose excessive use of the Internet was causing academic, social, and interpersonal problems. Other results showed that pathological Internet users had lower self-esteem and were more socially disinhibited. However, there was no significant difference in GHQ scores. These results are discussed in relation to the methodological shortcomings of research in the area as a whole.     

Speech-specific auditory processing: where is it?

Are speech-specific processes localized in dedicated cortical regions or do they emerge from developmental plasticity in the connections among non-dedicated regions? Here we claim that all the brain regions activated by the processing of auditory speech can be re-classified according to whether they respond to non-verbal environmental sounds, pitch changes, unfamiliar melodies, or conceptual processes. We therefore argue that speech-specific processing emerges from differential demands on auditory and conceptual processes that are shared by speech and non-speech stimuli. This has implications for domain- vs. process-specific cognitive models, and for the relative importance of segregation and integration in functional anatomy.     

Optimal predictions in everyday cognition

Human perception and memory are often explained as optimal statistical inferences that are informed by accurate prior probabilities. In contrast, cognitive judgments are usually viewed as following error-prone heuristics that are insensitive to priors. We examined the optimality of human cognition in a more realistic context than typical laboratory studies, asking people to make predictions about the duration or extent of everyday phenomena such as human life spans and the box-office take of movies. Our results suggest that everyday cognitive judgments follow the same optimal statistical principles as perception and memory, and reveal a close correspondence between people's implicit probabilistic models and the statistics of the world.     

Theory-based Bayesian models of inductive learning and reasoning

Inductive inference allows humans to make powerful generalizations from sparse data when learning about word meanings, unobserved properties, causal relationships, and many other aspects of the world. Traditional accounts of induction emphasize either the power of statistical learning, or the importance of strong constraints from structured domain knowledge, intuitive theories or schemas. We argue that both components are necessary to explain the nature, use and acquisition of human knowledge, and we introduce a theory-based Bayesian framework for modeling inductive learning and reasoning as statistical inferences over structured knowledge representations.     

Effects of a cognitive-behavioural internet program on depression, vulnerability to depression and stigma in adolescent males: a school-based controlled trial

This study evaluated the effectiveness of a cognitive behaviour therapy Internet program (MoodGYM) for depressive symptoms, attributional style, self-esteem and beliefs about depression, and on depression and depression-vulnerable status in male youth. A total of 78 boys age 15 and 16 years were allocated to either undertake MoodGYM or to standard personal development activities. Outcomes were measured before commencement, post-program and 16 weeks post-program. There were no significant between-group differences in change scores pre- to post- or pre- to follow-up using the intention to treat sample or for participants with post- and/or follow-up data. For boys completing 3 or more modules there were small relative benefits of MoodGYM for depressive symptoms (Effect Size, ES = 0.34), attributional style (ES = 0.17) and self-esteem (ES = 0.16) at post-program, although only the effect for self-esteem was sustained at follow-up. Both groups showed improvement in their beliefs about depression at follow-up, with the control group showing a moderate relative benefit (ES = 0.40). While the numbers are small, there was a reduction in the risk of being depressed in the MoodGYM group of 9% at post-treatment compared with a slightly increased risk for the control group. The risk of being classified as vulnerable to depression reduced by 17% in the MoodGYM group at post-treatment compared with no change in risk for the control group. These reductions in risk for the MoodGYM group were not sustained at follow-up. The limitations of the study highlight several important challenges for MoodGYM and other self-directed Internet cognitive behaviour therapy programs. These include how to ensure enough of the program is received and that people who could potentially benefit access the program and continue to remain engaged with it, and how to enhance the sustainability of any benefits.
