Use of the Suicide Probability Scale (SPS) with Adolescents

This study examined the utility of the Suicide Probability Scale (SPS) by comparing results obtained with a sample of 217 normal adolescents (M = 16.2 years) to the findings obtained in Cull and Gill's (1988 ) standardization effort. The present sample scored significantly higher than Cull and Gill's normative sample in SPS item, subscale, and total scores. In addition, the SPS generally failed to discriminate between the present, adolescent sample and Cull and Gill's inpatient psychiatric sample. Moreover, item-subscale correlations obtained for the present sample often differed from those reported by Cull and Gill, and factor analysis of SPS item scores failed to replicate Cull and Gill's four-factor solution. Findings suggest the need for caution when using the SPS to assess adolescent suicide potential and underscore the need for additional research regarding the instrument's efficacy in distinguishing between normal and suicidal adolescents.     

Is A Person Thinking About Suicide Likely to Find Help on the Internet? An Evaluation of Google Search Results

It is unclear whether individuals searching the Internet for assistance with thoughts of suicide are likely to encounter predominantly helpful or harmful resources. This study investigated websites retrieved by searching Google for information and support for suicidal thoughts. Google searches retrieved a high percentage of irrelevant websites (26%, n = 136). Of the 329 relevant websites retrieved, the majority were suicide preventive (68%); however, a considerable proportion of sites expressed mixed (22%) or neutral (8%) suicide attitudes, and 1% were explicitly pro‐suicide. The results highlight a need for suicide prevention organization websites to be made more easily accessible. In the meantime, clinicians should be aware of appropriate websites to recommend to clients.     

Effects of sad mood on time-based prospective memory

Very little is known about the influence of emotional factors on prospective memory (PM) performance. We used a mood induction (neutral or sad) to examine the effects of sad mood on time-based PM performance. Based on Ellis and Ashbrook's (1988) resource allocation model, we hypothesised an adverse effect of sad mood on PM performance. Results revealed that participants who responded to the sad mood induction procedure showed reduced PM performance that mainly resulted from a decreased timeliness of PM responses, but only in the first half of the task. Mood effects on PM could be explained in terms of reduced and less accurate monitoring. Implications for concepts of PM and the assessment of emotional after-effects are discussed.
