Adolescence, when suicidal ideation and behaviors often begin, might offer an important window to understand the causes and prevent the progression of suicide phenomena. The need for frameworks to organize the fragmented field has been noted, but few studies are theoretically driven. An important recent contribution to understanding suicidality is Joiner's (2005) Interpersonal-Psychological Theory of Suicide (IPTS). This article reviews the evidence for the applicability of the IPTS in adolescence. Seventeen studies of adolescents that specifically tested or interpreted findings in the light of Joiner's theory or the IPTS were located. In addition, several recent reviews of the literature on suicidality in adolescence covered information relevant to the IPTS. There is some support for the theory in adolescence, particularly with regard to its most novel component, the association between acquired capability and suicide attempt. In summary, we find this theory to be a promising heuristic to organize the disparate studies in suicide research. Future challenges and directions for researchers seeking to test and elaborate the applicability of the IPTS in adolescence include: adaptations of instruments to the developmental stage, capturing of imminent risk, and consideration of whether the current model is underspecified. Age might moderate adult findings that give impulsivity an indirect role in suicide attempts. [ABSTRACT FROM PUBLISHER]

Suicide is the second leading cause of death among youth and has become a serious public health problem. There has been limited research on strategies to decrease the likelihood of reattempt in adolescents. As phase one of a treatment development study, clinicians, parents, and adolescents participated in qualitative interviews in order to gain new perspectives on developing a targeted intervention and a safety plan phone application for suicide prevention. Participants indicated that transition of care, specific treatment targets, and safety planning were important parts of treatment. In addition, all participants endorsed the use of a smartphone application for these purposes. [ABSTRACT FROM AUTHOR]

The present investigation examined neurocognitive functioning, focusing on executive functioning (EF), in 39 children and adolescents with Major Depressive Disorder (MDD) and 24 healthy control subjects all ages 8 to 17 years. The Wechsler Intelligence Scale for Children-Third Edition along with several measures of executive functioning including the Wisconsin Card Sorting Task, Trail Making Test, Controlled Oral Word Association Test, and the Stroop Color Word Test were administered. The neurocognitive profiles for the group of depressed children and adolescents were grossly intact as most scores on intellectual and EF measures fell within the average range and did not differ from the comparison group. Mental processing speed was decreased in the MDD versus normal control group and 27% of the depressed group performed below average on the Trail Making Test. This investigation provided a good base from which to compare future literature on EF in outpatients with early-onset MDD. [ABSTRACT FROM AUTHOR]
