Abstract:
Objectives: Perceived stress is emerging as a potential contributing factor in suicide-related ideation in older adults. We hypothesized higher levels of perceived stress would be associated with increased self-reported suicidal ideation independent of depressive symptom severity.Methods: This study used data from community-dwelling older adults aged ≥65 with a current diagnosis of major depression. Eligible participants completed measures of depression symptom severity (Hamilton Depression Rating Scale-17 item), current suicidal ideation (Geriatric Suicide Ideation Scale), and perceived stress (Perceived Stress Scale).Results: Participants were 225 older adults with a mean age of 71.4 (SD = 5.6). Sixty-five percent of the sample was female. Fifteen percent of the variance in suicidal ideation was accounted for by lower education (p = .03), male sex (p = .03) and higher current perceived stress (p < .001). Specifically, stress accounted for 12% of the variance.Conclusions: Perceived stress is an important avenue to increase identification of individuals with a higher risk of suicide-related ideation among older adults with a current diagnosis of major depression.Clinical Implications: Screening for perceived stress may allow for improved screening and prevention of suicidal activity in depressed older adults.

Freezing-Point Depression to Determine an Unknown Compound
When a solid compound is dissolved in a solvent, the freezing point of the resulting solution is lower than that of the pure solvent. This phenomenon is known as freezing-point depression, and the change in temperature is directly related to the molecular weight of the solute. This experiment is designed to find the identity of an unknown compound by using the phenomenon of freezing-point depression to determine its molecular...
