Risk Factors of a Suicide Reattempt by Seasonality and the Method of a Previous Suicide Attempt: A Cohort Study in a Japanese Primary Care Hospital

Suicide has a great impact on the individual whose life is lost and the bereaved family members. The risk of a suicide reattempt is particularly high during the first 12 months after a suicide attempt. In this cohort study, risk factors for a suicide reattempt were explored among 291 patients at suicide risk. Clinical and demographic data were collected from a Japanese primary care hospital. Past psychiatric history and multiple diagnoses were associated with suicide reattempts in both genders. Drug overdose, past psychiatric history, and the summer season were linked to suicide reattempts among males. Past psychiatric history and multiple diagnoses were linked to suicide reattempts among females. Appropriate assessment of past psychiatric history, season and method of suicide attempt, gender, and diagnosis may play a role in preventing suicide.     

Postdeployment Suicide Risk Increases Over a 6‐month Period: Predictors of Increased Risk among Midwestern Army National Guard Soldiers

National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time.     

Friendship,Depression, and Suicide Attempts in Adults: Exploratory Analysis of a Longitudinal Follow‐Up Study

Social support is thought to protect against the risk of suicidal behavior in young people and late life, but less is known about the role of friendship in adults. We explored the effect of friendship on suicide attempt risk during 1‐year follow‐up of 132 adults presenting with major depressive episode (MDE). Items from the Social Adjustment Scale–Self‐Report were used as an index of frequency and quality of recent friendship contacts. Survival methods tested associations of friendship with risk of suicide attempt, recurrent MDE, and related outcomes during follow‐up. Impaired friendship predicted greater risk of suicide attempt in an unadjusted Cox model. This association was stronger for quality (p = .009) than frequency (p = .081) of friendship contacts. In the adjusted model, the effect of friendship on suicide attempts was largely explained by self‐reported depression severity. Friendship has a potentially bidirectional relationship with depression, and its effect on suicidal behavior appears to occur through its relationship with depression. Future research should examine the effect of antidepressant treatment on friendship and be designed to test mediation models of relationships between friendship, depression, and suicidal behavior.     

The Contribution of Neuroimaging to the Study of Language and Aphasia

New structural and functional imaging methods continue to be developed at a rapid pace. In the last 25 years, advanced imaging techniques have provided insights into how language is represented and processed in the brain and how it can be disrupted by damage to, or dysfunction of, various parts of the brain. Imaging studies have also yielded new information regarding how individuals recover language after stroke. We briefly review the strengths and weaknesses of the various radiological methods currently used to study language and aphasia.     

Multiple-probe technique: a variation on the multiple baseline

Multiple-baseline and probe procedures are combined into a “multiple-probe” technique. The technique is designed to provide a thorough analysis of the relationship between an independent variable and the acquisition of a successive-approximation or chain sequence. It provides answers to the following questions: (1) What is the initial level of performance on each step in the training sequence? (2) What happens if sequential opportunities to perform each next step in the sequence are provided before training on that step? (3) What happens when training is applied? (4) What happens to the performance of remaining steps in the sequence as criterion is reached in the course of training each prior step? The technique features: (1) one initial probe of each step in the training sequence, (2) an additional probe of every step after criterion is reached on any training step, and (3) a series of “true” baseline sessions conducted just before the introduction of the independent variable to each training step. Intermittent probes also provide an alternative to continuous baseline measurement, when such measurement during extended multiple baselines (1) may prove reactive, (2) is impractical, and/or (3) a strong a priori assumption of stability can be made.
