Telehealth Monitoring of Patients with Schizophrenia and Suicidal Ideation

A telehealth system was developed to monitor risk following hospitalization for suicidal ideation. We hypothesized that 3 months of telehealth monitoring will result in a greater reduction in suicidal ideation. Veterans with schizophrenia admitted with recent suicidal ideation and/or a suicidal attempt were recruited into a discharge program of VA Usual Care with daily Health Buddy© monitoring (HB) or Usual Care (UC) alone. Fifteen of 25 were randomized to HB and 10 received UC. Daily adherence in the use of the HB system during months 1–3 was, respectively, 86.9%, 86.3%, and 84.1%. There were significant improvements in Beck Scale for Suicide Ideation scores in HB participants. There were no changes in depressive symptoms. Telehealth monitoring for this population of patients appears to be feasible.     

The Validity of a Brief Risk Assessment Tool for Predicting Suicidal Behavior in Veterans Utilizing VHA Mental Health Care

Suicide risk among military veterans is an important and ongoing concern. The Veterans Administration (VA) mandates suicide risk screening of all veterans seen for mental health issues, but little is known about the effectiveness of this screening. A retrospective chart review to examine all suicide risk screens at VA San Diego between October and December 2012 (n = 3,365) was conducted to assess whether results were associated with suicidal behavior over the subsequent 12 months. Patients judged to be at increased risk for suicide were 3 to 16 times more likely to attempt suicide and 7 to 25 times more likely to engage in self‐directed violence over the next 12 months compared with others. The screening tool may be a useful addition to clinical practice.     

The Supposed Effect of Interactive Imagery in Paired Associate Learning

Previous experiments designed to investigate the effects of interactive imagery in paired associate learning have included the confounded variable of intralist similarity: Images of objects interacting have corresponded to pairs with different connectives, and images of independent objects have corresponded to pairs with the same connective (the conjunction 'and'). For the 'different' group of our first experiment, the members of the different pairs were linked by different connectives, most of which denoted an action. For the 'same' group, the members were linked by the same connective, usually one denoting an action. For the 'and' group, the members were linked by the connective 'and'. Cued recall by the 'different' group was superior to that of the other two groups. Recall by the 'same' and 'and' groups did not differ. Within the 'different' group, recall of 'and' pairs did not differ from the recall of 'action' pairs with which they had been mixed. In a second experiment, subjects were required to match the members of a pair. Analogous results were obtained. Overall, the findings imply that recall effects that have previously been interpreted as being a result of interactive imagery may be the result merely of variations in intralist similarity.     

The structure of memory: Evidence concerning the recall of surface and background colour of shapes

In the first of four experiments, two groups of subjects were shown a series of cards, each displaying a different shape. For one group the shapes were of different colours, and each was located on either a black or a white background. For the other group a shape was black or white, and its background was coloured. Subjects in both groups were instructed to memorize the colour and brightness (black or white) assigned to each shape. Recall of the colours, in response to the names of the shapes, was superior for the group for which the shapes themselves had been coloured. In the other three experiments the finding was extended, with the aim of limiting possible explanations of the effect. One of these experiments showed that the effect is obtained when the relevant stimuli are imagined rather than being physically shown to a subject. This suggests that the effect is not the result of processes of attention that are dependent upon the perceptual analysis of a display. In discussion, it is argued that the effect may shed light on the constraints that govern the process of association. One hypothesis that specifically accounts for the results is that the structure of memory for visually presented information is that of a network of propositions.
