Exercise, pain, perceived family support, and quality of life in Korean patients with ankylosing spondylitis

Relations of habitual exercise and pain, perceived family support, and the quality of life in patients with functional class II for ankylosing spondylitis were explored. In a cross-sectional study perceived pain, family support, and quality of life were compared for 30 patients (23 women and 7 men whose mean age was 28.3 yr.+/-8.6 yr.) practicing exercise regularly and for 38 sedentary patients (31 women and 7 men whose mean age was 27.2+/-6.7 yr.). Exercising patients reported significantly lower pain, greater perceived family support, and increased quality of life than their sedentary peers. Pain ratings were significantly negatively correlated with the quality of life in both groups (r = -.26 in exercisers and r = -.50 in sedentary patients) and control group's perceived family support was significantly correlated .44 with quality of life. These results encourage further study of the associations of habitual exercise with perceived pain, family support, and quality of life.     

Distance perception mediated through nested contact relations among surfaces

In complex natural scenes, objects at different spatial locations can usually be related to each other through nested contact relations among adjoining surfaces. Our research asks how well human observers, under monocular static viewing conditions, are able to utilize this information in distance perception. We present computer-generated naturalistic scenes of a cube resting on a platform, which is in turn resting on the ground. Observers adjust the location of a marker on the ground to equal the perceived distance of the cube. We find that (1) perceived distance of the cube varies appropriately as the perceived location of contact between the platform and the ground varies; (2) variability increases systematically as the relating surfaces move apart; and (3) certain local edge alignments allow precise propagation of distance information. These results demonstrate considerable efficiency in the mediation of distance perception through nested contact relations among surfaces.     

Functional and connectivity changes during working memory in Huntington’s disease: 18 month longitudinal data from the IMAGE-HD study

Background

This study aimed to characterize, for the first time, 18 month longitudinal changes in both functional activation and functional connectivity during working memory in premanifest Huntington’s disease (pre-HD) and symptomatic HD (symp-HD).

Methods

Functional magnetic resonance imaging (fMRI) was used to investigate longitudinal changes in neuronal activity during working memory performance via an N-BACK task (0-BACK and 1-BACK) in 27 pre-HD, 17 symp-HD, and 23 control participants. Whole-brain analysis of activation and region-of-interest analysis of functional connectivity was applied to longitudinal fMRI data collected at baseline and 18 months follow-up.

Results

Compared with controls, the pre-HD group showed significantly increased activation longitudinally during 1-BACK versus 0-BACK in the lateral and medial prefrontal, anterior cingulate, primary motor, and temporal areas cortically, and caudate and putamen subcortically. Pre-HD far from onset, compared with controls, showed further longitudinal increases in the right and left dorsolateral prefrontal cortex (DLPFC). Longitudinal increased activation in anterior cingulate and medial primary motor areas were associated with disease burden in the pre-HD group. Moreover, in pre-HD increased activation over time in primary motor and putamen regions were associated with average response time during 1-BACK performance. During 1-BACK, functional connectivity between the right DLPFC and posterior parietal, anterior cingulate, and caudate was significantly reduced over 18 months only in the pre-HD group.

Conclusions

Longitudinal reductions in connectivity over 18 months may represent an early signature of cortico-cortical and cortico-striatal functional disconnectivity in pre-HD, whereas the concomitant increased cortical and subcortical activation may reflect a compensatory response to the demands for cognitive resources required during task performance. Our findings demonstrate that functional imaging modalities have the potential to serve as sensitive methods for the assessment of cortical and subcortical responses to future treatment measures.     

2008 Revision of the Chinese Code of Ethical Use of Psychological Tests and Its Implementation Status

In response to the rapidly increasing application and abuse of psychological tests in China, the Psychometrics Division of the Chinese Psychological Society published the 2008 revisions of the Chinese Code of Ethical Use of Psychological Tests. We investigated the implementation status of the code 2½ years after its promulgation. Sample included 284 psychological professionals and psychology graduate students. The average accuracy rate for the appropriate use of psychological tests was 67.1% (range = 25.5–97.5%), with 10 items having accuracy rates below 45%. Participants remained uncertain about the clients' rights to information about the purpose, psychometric properties, and scores of the tests. The most frequent violations involved “using psychological tests without psychometric information for entertainment purposes” and “using SCL-90 to measure mental health of normal people.”     

Using online social media,Facebook, in screening for major depressive disorder among college students

This study explored the feasibility of using Internet social networking media in an online program for Major Depressive Disorder (MDD) screening and psychoeducation targeting college students. A Facebook advertisement targeted students at five colleges in the United States to complete a mental health research survey that screened for MDD using the Patient Health Questionnaire-9 (PHQ-9). Students who screened positive for MDD were offered an eightweek follow-up survey. Of the 259 students who consented to participate in the study, 26.7% screened positive for MDD, while only 14.2% were receiving treatment. The use of Facebook to advertise for online screening for MDD required very little start-up time, and the average cost was $11.45 per subject recruited. It is feasible to use online, commercially available social networking media such as Facebook for online screening for MDD among college students. However, conducting online screening and offering treatment resources alone did not increase treatment rate in this population.     

A Longitudinal Study of Nurses’ Work-Life Balance: a Case of a Regional Teaching Hospital in Taiwan

Work-life balance is essential for nurses who are in direct contact with patients in healthcare organizations. This study employs the measurement of nurses’ behaviors rather than the measurement of their perceptions to identify critical demographic variables influencing the work-life balance. A work-life balance dimension measured by a four-point frequency scale from the Chinese version of the Safety Attitudes Questionnaire is used to assess nurses’ behaviors in practice from a longitudinal viewpoint based on a regional teaching hospital in Taiwan. The results show that experience in organization, respondents reporting events in the past 12 months, and experience in position are three critical factors to impact nurses’ work-life balance. Moreover, “work all day without break,” “change the individual or family plan because of the work,” and “work overtime” are the most critical questions in the work-life balance that can be the targets for hospital management to enhance the balance of nurses’ work-life conditions in the hospital.

     

An attentional blink for nontargets?

In a typical attentional blink experiment, viewers try to detect two target items among distractors in a Rapid Serial Visual Presentation (RSVP): processing of the first target impairs participants' ability to recall a subsequent target at short stimulus onset asynchronies (SOAs). However, little is known about whether target detection interferes with memory for nontarget items. To answer this question, in two experiments, we employed a novel dual-task procedure: participants searched for a word target (e.g., "a four-footed animal") and then were tested for recognition of nontarget words. Detection of the target word, which was present on half the trials, produced a standard attentional blink effect on memory for nontarget words, with lag 1 sparing followed by an attentional blink at longer lags. This result shows that target processing has a generalized effect on processing of later events, not only other targets.     

In the zone: flow state and cognition in older adults

The current study investigated the nature of the flow state among older adults. Flow is a pleasurable experiential state that occurs during full-capacity engagement in which an individual is performing at a level that is matched with the demands of the task. Each participant completed a scale assessing dimensions of flow in a particular activity selected by the participant. More cognitively demanding activities elicited higher levels of flow for those with higher fluid ability, but lower levels of flow for those with lower fluid ability. This pattern was reversed for activities that were low in demand. Our data highlight the potential importance of considering motivational states such as flow in understanding cognitive optimization in adulthood.     

Attachment-related differences in perceptions of an initial peer interaction emerge over time: Evidence of reconstructive memory processes in adolescents

This study examined whether attachment, assessed using the Adult Attachment Interview (AAI; George, Kaplan, & Main, 1996) was linked to how adolescents reconstructed their memory for an initial interaction with an unfamiliar peer. Adolescents (N = 189, 62% female) completed a 10-min laboratory task with a student whom they did not know. Immediately following this task, adolescents rated their perceptions of the interaction. Adolescents completed the same perception measure 2 weeks later. Although adolescents classified as secure and insecure on the AAI did not differ in how they perceived unfamiliar peers initially, attachment-related differences emerged over time. Insecure adolescents remembered the interactions as less positive and more negative and also reported being treated with greater hostility than they had initially reported 2 weeks earlier. In contrast, secure adolescents' memories for the negative aspects of the interaction and for hostile treatment remained stable, although, like insecure adolescents, they remembered the conflicts as being less positive than initially reported.

Reconstructive memory related to adolescent-parent conflict interactions: the influence of attachment-related representations on immediate perceptions and changes in perceptions over time

This investigation examined the hypothesis that individuals change, over time, their perceptions of interactions with attachment figures in ways that are consistent with their attachment-related representations of those individuals. In an original and a replication study, adolescents participated in laboratory conflict discussions with each of their parents. Adolescents rated their perceptions of the interactions immediately after the conflict discussions, then again 6 weeks later. Results indicated that (a) adolescents' immediate perceptions of the interactions were influenced by their attachment-related representations of their parents, and (b) adolescents' perceptions, over a period of 6 weeks, shifted such that their later perceptions were more congruent with their attachment-related representations than were their immediate perceptions. Implications for the continuity of relational models and relationship patterns are discussed.
