Does unstable mood increase risk of suicide? Theory, research and practice

Palmier-Claus, J.E., Taylor, P.J., Varese, F., Pratt, D.·2012·Journal of Affective Disorders

Abstract

Background Suicide represents a substantial problem, with significant societal and personal impact. The identification of factors influencing suicide risk is an important step in preventing self-harming behaviour. In this article the authors explore whether emotional instability increases risk of suicide, beyond that of mood intensity.Method This article provides a summary of existing theory and indirect evidence in support of an association between emotional instability and suicidality. A systematic literature search (Embase, Medline, PsychInfo) was carried out on literature conducted up to October, 2011. Meta-analysis was used to assess the strength of the proposed association.Results The systematic search identified 20 journal articles meeting the inclusion criteria, including retrospective questionnaire design studies and research conducted across several time-points. Meta-analysis revealed a moderate association, which remained statistically significant even when only including studies conducted over multiple time-points. This effect was attenuated, but remained significant, when controlling for study selection bias.Limitations Retrospective questionnaire studies failed to adequately control for mood level. Little is still currently understood about the types of emotional instability (e.g., dysoria, anxiety) most associated with suicidality.Conclusions Future avenues of investigation include micro- to macro-longitudinal research and the differentiation of emotion subtypes and instability metrics. Momentary assessment techniques may help to detect subtle fluctuations in mood leading to more effective and immediate intervention. Psychosocial intervention strategies for treating unstable emotions are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
