Behavioral and Psychological Symptoms that Predict Cognitive Decline or Impairment in Cognitively Normal Middle-Aged or Older Adults: a Meta-Analysis

Neuropsychology Review - Epidemiological studies have revealed that behavioral and psychological (or non-cognitive) symptoms are risk factors for cognitive decline in older adults. This study aimed...     

The Crisis Support Scale: psychometric qualities and further validation

The objective of the present study was to provide a further validation of the Crisis Support Scale, which is a short scale for measuring social support after a crisis has occurred. The data from eleven trauma studies of 4213 subjects were used to investigate the psychometric properties of the scale and the differences that emerge due to age, gender, and type of trauma. The scale appears to be very robust. Some aspects of crisis support seem to decrease as time goes by while others increase. Women survivors report less support than men both right after the trauma and later on. The younger survivors tend to report the least support in the acute phase although this picture is reversed later on. The various types of trauma have different item profiles, which supports the concurrent validity of the scale.     

Why a superman cannot help a tsunami: activation of grammatical class influences resolution of young and older adults' tip-of-the-tongue states

Young (aged 18-23), young-old (aged 61-73), and old-old (aged 75-89) adults saw general knowledge questions whose answers were designated target words. Participants responded that they knew, did not know, or were having a tip-of-the-tongue (TOT) state for the answer. After TOT states, participants saw a 5-word list in which 1 was a "prime" containing the target's first syllable and that shared or differed in part of speech from the target. The question was then presented again, and target retrieval was attempted. Results revealed age differences in resolution of TOT states as a function of the prime's grammatical class. Following different part-of-speech primes, young and young-old adults showed increased resolution of TOT states relative to phonologically unrelated words, whereas old-old adults did not. In contrast, old-old adults demonstrated decreased resolution of TOT states following same part-of-speech primes, whereas young and young-old adults' TOT resolution was unaffected. These findings are consistent with interactive activation theories of speech production in which phonology can influence lexical selection and also suggest an increased susceptibility to phonological competitors in the later stages of the aging process.     

Bootstrapping to test for nonzero population correlation coefficients using univariate sampling

This article proposes 2 new approaches to test a nonzero population correlation (rho): the hypothesis-imposed univariate sampling bootstrap (HI) and the observed-imposed univariate sampling bootstrap (OI). The authors simulated correlated populations with various combinations of normal and skewed variates. With alpha set=.05, N> or =10, and rho< or =0.4, empirical Type I error rates of the parametric r and the conventional bivariate sampling bootstrap reached .168 and .081, respectively, whereas the largest error rates of the HI and the OI were .079 and .062. On the basis of these results, the authors suggest that the OI is preferable in alpha control to parametric approaches if the researcher believes the population is nonnormal and wishes to test for nonzero rhos of moderate size.     

Desire for euthanasia or physician-assisted suicide in palliative cancer care.

OBJECTIVE: To investigate the attitudes of terminally ill individuals toward the legalization of euthanasia or physician-assisted suicide (PAS) and to identify those who would personally desire such a death. DESIGN: In the Canadian National Palliative Care Survey, semistructured interviews were administered to 379 patients who were receiving palliative care for cancer. Patients who expressed a desire for physician-hastened death were followed prospectively. MAIN OUTCOME MEASURES: Attitudes toward the legalization of euthanasia or PAS were determined, as was the personal interest in receiving a hastened death. Demographic and clinical characteristics were also recorded, including a 22-item structured interview of symptoms and concerns. RESULTS: There were 238 participants (62.8%) who believed that euthanasia and/or PAS should be legalized, and 151 (39.8%) who would consider making a future request for a physician-hastened death. However, only 22 (5.8%) reported that, if legally permissible, they would initiate such a request right away, in their current situations. This desire for hastened death was associated with lower religiosity (p=.010), reduced functional status (p=.024), a diagnosis of major depression (p<.001), and greater distress on 12 of 22 individual symptoms and concerns (p<.025). In follow-up interviews with 17 participants, 2 (11.8%) showed instability in their expressed desire. CONCLUSION: Among patients receiving palliative care for cancer, the desire to receive euthanasia or PAS is associated with religious beliefs; functional status; and physical, social, and psychological symptoms and concerns. Although this desire is sometimes transitory, once firmly established, it can be enduring.     

Is the Effect of Behavioral Synchrony on Cooperative Behavior Mediated by Pain Threshold?

Synchronized behavior results in a variety of prosocial behaviors. Research has also implicated that interpersonal synchrony affects pain thresholds, inferred as indicative of endorphin levels. The current study was designed to see if these pain threshold effects mediated the effect of synchrony on interpersonal cooperation. Twenty six individuals were randomly assigned to complete a 30 minute run on a treadmill in either a synchronized or nonsynchronized condition. Pain threshold was measured both before and after exercise as an indicator of endorphin activity. A postrun social investment game measured interpersonal cooperation. Analyses showed that there was a significant direct relationship between condition and cooperation but that this effect was not mediated by pain threshold.     

Mental Health Services in Juvenile Correctional Facilities: A National Survey of Clinical Staff

This study determined the use of best practices in providing mental health services to youth within juvenile correctional facilities. A national sample of 94 (49.7 %) lead clinical staff from all available and qualifying facilities responded to a mail and on-line survey. There were no statistically significant differences across respondents versus nonrespondents for security level, gender served, or census region of facilities. Specifically, we examined the provision of facility-wide mental health programming, individual, group, and family counseling, and case management services. Examination of these services included the use of evidence-based interventions provided through an established curriculum and methods used to evaluate the effectiveness of the interventions. We also examined staff involvement, and the perceived quality of services and barriers to providing interventions. Participants reported using a variety of evidence-based interventions; however, participants also acknowledged using other approaches that may not have empirical support. Additionally, although at least half of the participants reported mandatory individual and group counseling, less than a third of the participants reported that their facilities required family counseling. Clinical staff also reported a variety of methods used for evaluating the effectiveness of mental health services. Additional findings, as well as implications for research and practice, are discussed.     

Psychometric Properties of the French Version of the Pictorial Scale of Perceived Movement Skill Competence for Young Children (PMSC)

ObjectiveThe objective of this study was to examine the psychometric properties of a French version of the pictorial scale of Perceived Movement Skill Competence for Young Children (PMSC), which is aligned with the third version of the Test of Gross Motor Development.MethodA sample of 219 French-speaking Canadian children (5 to 12 years old) participated in this study.ResultsResults supported the factor validity and reliability of a 13-item version of the PMSC encompassing two factors (i.e., ball skills and locomotor skills). Subsequent analyses supported the weak, partial strong, and partial strict invariance of responses to the PMSC as a function of sex. Additionally, analyses revealed that boys displayed significantly higher perceived ball skill competence than girls. Results also supported a lack of differential item functioning (DIF) and latent mean differences as a function of body mass index and physical activity/sport involvement, but revealed evidence of DIF and latent mean differences as a function of age. More precisely, these results show that older children displayed significantly: (a) higher scores on the sliding item and lower scores on the kicking item relative to younger children; and (b) lower scores on perceived locomotor skills competence than younger children.ConclusionOverall, results suggest that the French version of the PMSC has acceptable psychometric properties and can be confidently used in research or practice to assess children's perceived movement skill competence.     

Australian psychologists' attitudes towards suicide and self‐harm

An exploratory study of 81 Australian psychologists' attitudes towards suicide and self‐harm was undertaken. Two attitudinal measures, one knowledge measure and demographic information, were used to assess the relationships between attitudes, knowledge, gender, age, years of professional experience, and previous experience with suicidal and self‐harming clients. Among this sample, attitudes towards suicide and self‐harm were generally positive and participants displayed high levels of knowledge of self‐harm. Age and years of experience were related to participants' attitudes, with younger psychologists reporting greater confidence in working with these clients and believing in the right of an individual to decide when to die. Future research is needed to determine the impact of psychologists' attitudes on their behaviour towards suicidal and self‐harming clients.
