Cross-national comparisons of the association between alcohol consumption and deliberate self-harm in adolescents

How differences in drinking patterns may affect the impact of alcohol consumption on deliberate self-harm among adolescents is explored in this international comparative study. Schools in Australia, Belgium, England, Hungary, Ireland, the Netherlands, and Norway (N = 30,532) were surveyed. In all countries the risk of deliberate self-harm was significantly elevated among adolescents who reported some or numerous episodes of intoxication, controlling for confounding factors. The results support the assumption that intoxication is significantly related to the association between alcohol consumption and deliberate self-harm in adolescents.     

The Developmental Leadership Questionnaire (DLQ): some psychometric properties

The development leadership model (Larsson et al., 2003), designed to introduce refinements to the transformational leadership model, has been adopted for use in the Swedish Armed Forces. The Developmental Leadership Questionnaire (DLQ) was constructed to measure important parts of the model. The main aim of the study was to evaluate some psychometric properties of the DLQ. Most analyses are based on two subsets of individuals from a sample mostly consisting of male Swedish, military officers, each of whom has rated a given leader (n = 450 and 449 respectively). A second sample consisted of Swedish military cadets (n = 141). The dimensionality was assessed with a confirmatory factor analysis. Most DLQ scales were reasonably well reproduced and showed high or acceptable internal consistency. When related to perceived results of leadership (self-rated by leaders and rated by subordinates), results from multiple regression analyses supported what could be predicted by the theoretical model. It was concluded that the DLQ has acceptable psychometric properties and that the theoretical refinements introduced to the developmental leadership model were empirically supported.     

Recollective experience in odor recognition: Influences of adult age and familiarity

We examined recollective experience in odor memory as a function of age, intention to learn, and familiarity. Young and older adults studied a set of familiar and unfamiliar odors with incidental or intentional encoding instructions. At recognition, participants indicated whether their response was based on explicit recollection (remembering), a feeling of familiarity (knowing), or guessing. The results indicated no age-related differences in the distribution of experiential responses for unfamiliar odors. By contrast, for familiar odors the young demonstrated more explicit recollection than the older adults, who produced more know and guess responses. Intention to learn was unrelated to recollective experience. In addition, the observed age differences in remember responses for familiar odors were eliminated when odor naming was statistically controlled. This suggests that age-related deficits in activating specific odor knowledge (i.e., odor names) play an important role for age differences in recollective experience of olfactory information.     

Proportional and nonproportional transfer of movement sequences

Two experiments were designed to determine participants' ability to transfer a learned movement sequence to new spatial locations. A 16-element dynamic arm movement sequence was used in both experiments. The task required participants to move a horizontal lever to sequentially projected targets. Experiment 1 included 2 groups. One group practised a pattern in which targets were located at 20, 40, 60, and 80° from the start position (long sequence). The other group practised a pattern with targets at 20, 26.67, 60, and 80° (mixed sequence). Both groups were tested 24 hours later on the long, mixed, and short sequence. The short sequence was considered a proportional transfer for the long acquisition group because all the amplitudes between targets were reduced by the same proportion. Nonproportional transfer occurred when the amplitudes between targets did not have the same proportions as those for their practice sequence (e.g., long sequence to mixed sequence or vice versa). The results indicated that participants could effectively transfer to new target configurations regardless of whether the transfer required proportional or nonproportional spatial changes to the movement pattern. Experiment 2 assessed the effects of extended practice on proportional and nonproportional spatial transfer. The data indicated that while participants can effectively transfer to both proportional and nonproportional spatial transfer conditions after 1 day of practice, they are only effective at transferring to proportional transfer conditions after 4 days of practice. The results are discussed in terms of the mechanism by which response sequences become increasingly specific over extended practice in an attempt to optimize movement production.     

Interviewing children with the cognitive interview: assessing the reliability of statements based on observed and imagined events

This paper investigated whether criteria stemming from the Reality Monitoring (RM) framework could be trusted to assess the reliability of statements obtained by the use of a cognitive interview (CI). Fifty-eight children, aged 10-11, participated. One-third watched a film about a fakir and were then interviewed according to a CI (n= 19). The remaining two-thirds made up a story about a fakir and were then interviewed according to either a CI (n= 21), or a structured interview (SI) (n= 18). The CI statements based on observed events contained more visual, affective, spatial and temporal information compared to CI statements based on imagined events. The CI statements based on imagined events did not differ from the SI statements based on imagined events. Considerable developmental work is recommended to turn the RM technique to a reliable test that could be used by practitioners.     

Factors predicting success in picture naming in Alzheimer's disease and primary progressive aphasia

The aim of the present study was to determine the predictive value of all important variables in the picture naming performance of 8 patients with probable Alzheimer's disease (AD) and 8 patients with primary progressive aphasia (PPA). The experimental investigation controlled for (i) visual complexity, (ii) name agreement on dominant response, (iii) age of acquisition, (iv) frequency, (v) word length, (vi) concept familiarity, and (vii) category membership. The results of the multiple regression analyses showed that age of acquisition and name agreement were significant for 10/16 subjects. Visual complexity, frequency, familiarity, and category were also significant for four patients respectively. Word length had no effect. These results are at variance with those of series of patients with AD (Gaillard et al., 1998) and with PPA (Lambon Ralph et al., 1998) where concept familiarity was found to be one of the most predictive factors of naming success.     

Prevalence of auditory verbal hallucinations in a general population: A group comparison study

The present study was specifically designed to investigate the prevalence of auditory verbal hallucinations (AVH) in the general population, and sought to compare similarities and differences regarding socio‐demographics, mental health and severe life events between individuals who have never experienced AVH with those who had. The study also aimed to compare those who sought professional help for their experience of AVH with those who had not sought help. Through a postal questionnaire, 2,533 participants ages 18 and over from a national survey completed the Launay‐Slade Hallucinations Scale and other measures examining AVH characteristics and other areas related to AVH. In total, 7.3% of the sample reported a life‐time prevalence of AVH. Those with AVH were more likely to be single and unemployed, reported higher levels of depression and anxiety, and experienced a higher number of severe life events compared with those without AVH. Only 16% of those who experienced AVH in the general population sought professional help for these experiences. Compared to those who did not seek professional help, participants that had were more likely to experience AVH with a negative content, experience them on a daily basis, undergo negative reactions when experiencing AVH, and resist AVH. In conclusion, the prevalence of AVH was found to be relatively high. The results also revealed higher levels of reduced mental health for individuals who sought professional help, followed by those who did not, compared with those who had never experienced AVH.
