Men's Motivation to Perform the Testicle Self-Exam: Effects of Prior Knowledge and an Educational Brochure

College men reported their attitude and intention to perform the testicle self-exam (TSE) and they rated the likelihood of various consequences of performing the TSE, as well as the likelihood that several other people approved of this behavior. Half of these men had read a brochure about the TSE before completing the questionnaire, and half had not. Also, about half had heard about the TSE prior to the experiment and the others had not. Men's beliefs about the consequences of doing the TSE clustered into two factors: Beliefs about practical consequences and beliefs about health consequences. Men with (vs. without) prior knowledge about the exam and men who read (vs. did not read) the brochure endorsed more positive beliefs about practical and health consequences and more positive TSE attitude and intention. However, the effect of the brochure was far stronger for men without than with prior knowledge. In addition, factors influencing TSE attitude and intention differed for men without versus with prior TSE knowledge. Although the findings were generally consistent with the theory of reasoned action, some findings supported elements of protection motivation theory. Implications for promoting the TSE are discussed.     

A randomized controlled trial of internet-based therapy in depression

Depression is among the most prevalent disorders worldwide. In view of numerous treatment barriers, internet-based interventions are increasingly adopted to “treat the untreated”. The present trial (registered as NCT01401296) was conducted over the internet and aimed to assess the efficacy of an online self-help program for depression (Deprexis). In random order, participants with elevated depression symptoms received program access or were allocated to a wait-list control condition. After eight weeks, participants were invited to take part in an online re-assessment. To compensate for common problems of online studies, such as low completion rates and unclear diagnostic status, reminders and incentives were used, and clinical diagnoses were externally confirmed in a subgroup of 29% of participants. Relative to the wait-list group, program users experienced significant symptom decline on the Beck Depression Inventory (BDI; primary outcome), the Dysfunctional Attitudes Scale (DAS), the Quality of Life scale (WHOQOL-BREF) and the Rosenberg Self-Esteem Scale (RSE). Compared to wait-list participants, symptom decline was especially pronounced among those with moderate symptoms at baseline as well as those not currently consulting a therapist. Completion (82%) and re-test reliability of the instruments (r = .72–.87) were good. The results of this trial suggest that online treatment can be beneficial for people with depression, particularly for those with moderate symptoms.     

Scientific Representations as Limiting Cases

In this essay, I shall show that the so-called inferential (Suárez 2003 and 2004) and interpretational (Contessa 2007) accounts of scientific representation are respectively unsatisfactory and too weak to account for scientific representation (pars destruens). Along the way, I shall also argue that the pragmatic similarity (Giere 2004 and Giere 2010) and the partial isomorphism (da Costa and French 2003 and French 2003) accounts are unable to single out scientific representation. In the pars construens I spell out a limiting case account which has explanatory surplus vis à vis the approaches which I have previously reviewed. My account offers an adequate treatment of scientific representation, or so I shall try to argue. Central to my account is the notion of a pragmatic limiting case, which will be characterized in due course.     

Sometimes,often, and always: Exploring the vague meanings of frequency expressions

The article describes a general two-step procedure for the numerical translation of vague linguistic terms (LTs). The suggested procedure consists of empirical and model components, including (1) participants’ estimates of numerical values corresponding to verbal terms and (2) modeling of the empirical data using fuzzy membership functions (MFs), respectively. The procedure is outlined in two studies for data from N = 89 and N = 109 participants, who were asked to estimate numbers corresponding to 11 verbal frequency expressions (e.g., sometimes). Positions and shapes of the resulting MFs varied considerably in symmetry, vagueness, and overlap and are indicative of the different meanings of the vague frequency expressions. Words were not distributed equidistantly across the numerical scale. This has important implications for the many questionnaires that use verbal rating scales, which consist of frequency expressions and operate on the premise of equidistance. These results are discussed for an exemplar questionnaire (COPSOQ). Furthermore, the variation of the number of prompted LTs (5 vs. 11) showed no influence on the words’ interpretations.     

Approaching Religiosity/Spirituality and Health from the Eudaimonic Perspective

Religiosity/spirituality (RS) has been linked to positive health outcomes across a large number of studies, with these effects seen most strongly among disadvantaged groups such as minorities, women, and those of lower socioeconomic status (SES). Given that disadvantaged groups typically have worse health outcomes and not better, it is not clear why the effects of RS are stronger for disadvantaged groups. A key difficulty in understanding the relationship between RS and health lies in the theoretical perspectives used in research. Health and well‐being is typically assessed from the hedonic perspective which emphasizes pleasure and happiness as important outcomes and assumes that difficult life situations contribute to negative health. The eudaimonic perspective, on the other hand, emphasizes meaning and relationships, and assumes that difficult life situations can contribute to increased meaning in life and stronger relationships. The eudaimonic perspective provides a better framework for understanding why RS leads to better health for disadvantaged groups for three reasons. First, having meaning in life and strong relationships are related to positive health outcomes and buffer the negative effects of stress. Second, in addition to being more religious, disadvantaged groups report lower hedonic well‐being and report higher eudaimonic well‐being. Third, low SES religious individuals have better than expected health outcomes and low SES materialistic individuals have worse than expected health outcomes. Overall, the eudaimonic perspective better accounts for the research findings in RS and health and provides a strong foundation for future research in this area.     

Psychosoziale Belastungen von Bahnpendlern

The increasing number of commuters in our society raises the question of the consequences, in particular of psychiatric and somatic symptoms and the quality of life. A total of 407 commuters at the main railway stations in Stuttgart and Ulm (southern Germany) were included in a study in order to assess the psychiatric symptoms of commuters and if they are able to make use of psychosocial care despite the long periods of time spent commuting to work. An important result was that especially long-term commuters pay a high price: 31.3% of male and 37.3% of female commuters exceeded the cut-off point for psychiatric illness in the Outcome Questionnaire (OQ-45.2). The high prevalence of psychiatric disorders coincides with a high rate of unmet needs so that a high rate of false and under-treatment for commuters can be assumed.     

Limits of the Retrieval-Inhibition Construct: List Segregation in Directed Forgetting

The authors hypothesized that retrieval inhibition in list method directed forgetting could be improved by presenting a task that maximized the segregation step of the retrieval-inhibition process. In Experiment 1, they presented lists of semantically related words in a list method directed-forgetting task to maximize retrieval inhibition. Contrary to predictions, this manipulation eliminated the directed-forgetting effect. The authors further investigated the results of Experiment 1 in Experiments 2 and 3 by manipulating recall instructions and by presenting lists that contained both a categorized and an unrelated list-half. They found directed-forgetting effects for semantically related word lists when participants were asked to recall only the TBR (to-be-remembered) items but not when participants were asked to recall both the TBF (to-be-forgotten) and TBR items. They also found that directed-forgetting effects were not produced when categorized items were presented in the 1st list.     

Emotional enhancement effect of memory: removing the influence of cognitive factors

According to the modulation hypothesis, arousal is the crucial factor in the emotional enhancement of memory (EEM). However, the multifactor theory of the EEM recently proposed that cognitive characteristics of emotional stimuli, e.g., relatedness and distinctiveness, also play an important role. The current study aimed to investigate the individual contribution of arousal to the neural correlates of the EEM by controlling for these additional cognitive factors. We observed the characteristic neuronal correlates of the EEM, in particular enhanced activity in the amygdala and hippocampus, which provides evidence for an arousal-driven EEM in the amygdala as proposed by the modulation hypothesis.     

When the half-full glass is appraised as half empty and memorised as completely empty: mood-congruent true and false recognition in depression is modulated by salience

Since the 1980s a large body of empirical effort has been devoted to mood-congruent memory (MCM) biases in clinical depression. Whereas there is broad, albeit not unequivocal, evidence that depressive patients retain negative-valenced memory items better than neutral material, few studies have investigated false memories in depression. In a pilot study we gathered support for both enhanced true and false memory for emotional material in depression. The present study aimed to extend these preliminary findings. In view of investigations suggesting that arousing and meaningful stimuli have facilitated access to memory, personal salience was considered a moderator for MCM. In the present study 21 depressed and 22 healthy participants were presented six false memory lists dealing with neutral, negative, and positive themes. At recognition, each item had to be appraised for its degree of valence subsequent to an old-new judgement. Pre-categorised and subjective valence did not discriminate groups. However, relative to controls depressed patients showed both more veridical as well as false recognition for items that concurrently elicited higher salience ratings in patients. In contrast, group differences in recognition performance did not significantly affect salience ratings. Results indicate that salience modulates MCM and may account for discrepancies in the literature.
