Trajectories of change in depression symptoms and suicidal ideation over the course of evidence-based treatment for depression: Secondary analysis of a randomised controlled trial of cognitive behavioural therapy plus fluoxetine in young people

Practitioner Review: Treatments for young people who self-harm - challenges and recommendations for research and clinical practice

BACKGROUND

Self-harm is very common in young people and is associated with suicide. Rates of both self-harm and suicide have increased in young people, particularly in females. There is a clear need to identify new approaches to prevent repeat self-harm.

METHOD

We significantly update and build on previous reviews with the aim of identifying issues in research relevant to clinical practice. We identify challenges in developing, implementing and evaluating treatments for self-harm in children and adolescents, suggest a way forward for research, and provide clear and practical guidance for clinicians on how to apply current research evidence in the real world.

RESULTS

Currently, there is limited evidence for effective interventions, other than some support for dialectical behaviour therapy for adolescents (DBT-A). To improve research and, by extension, clinical practice, future studies need to address psychosocial factors associated with youth self-harm and suicide, investigate the critical mechanism(s) of action, ensure trials are sufficiently powered and representative, and involve young people more actively in the design, implementation and evaluation of these approaches. Consideration should also be given to alternative research designs, such as pragmatic or adaptive clinical trials, as well as registry-based randomised controlled trials which leverage administrative data collected in routine clinical practice, to help meet these goals.

CONCLUSIONS

Recommendations for practice include undertaking comprehensive assessment and formulation, and offering DBT-A where indicated. There should be further development and evaluation (with input from young people) of Cognitive Behavioural-based Therapy adapted for young people. Greater attention to the role of the therapeutic relationship and family involvement (where possible) is also an important considerations, irrespective of the specific therapeutic modality. Finally, more consideration should be given to improving staff training to ensure all clinical staff feel equipped to treat young people who self-harm in a person-centred and compassionate manner.

Predictors of suicidal ideation severity among treatment-seeking young people with major depressive disorder: The role of state and trait anxiety

OBJECTIVE

Depression and suicidal ideation are closely intertwined. Yet, among young people with depression, the specific factors that contribute to changes in suicidal ideation over time are uncertain. Factors other than depressive symptom severity, such as comorbid psychopathology and personality traits, might be important contributors. Our aim was to identify contributors to fluctuations in suicidal ideation severity over a 12-week period in young people with major depressive disorder receiving cognitive behavioural therapy.

METHODS

Data were drawn from two 12-week randomised, placebo-controlled treatment trials. Participants (N = 283) were 15-25 years old, with moderate to severe major depressive disorder. The primary outcome measure was the Suicidal Ideation Questionnaire, administered at baseline and weeks 4, 8 and 12. A series of linear mixed models was conducted to examine the relationship between Suicidal Ideation Questionnaire score and demographic characteristics, comorbid psychopathology, personality traits and alcohol use.

RESULTS

Depression and anxiety symptom severity, and trait anxiety, independently predicted higher suicidal ideation, after adjusting for the effects of time, demographics, affective instability, non-suicidal self-injury and alcohol use.

CONCLUSIONS

Both state and trait anxiety are important longitudinal correlates of suicidal ideation in depressed young people receiving cognitive behavioural therapy, independent of depression severity. Reducing acute psychological distress, through reducing depression and anxiety symptom severity, is important, but interventions aimed at treating trait anxiety could also potentially be an effective intervention approach for suicidal ideation in young people with depression.

Suicide risk assessments: Why are we still relying on these a decade after the evidence showed they perform poorly?

Suicide deaths have a profound impact on whānau and community and are a tragic loss. However, from a statistical point of view, suicide is a relatively rare event. Predicting rare events is difficult, and the implications for suicide prevention were highlighted in an important editorial in this journal more than a decade ago, yet little seems to have changed. Risk assessment that focuses on accurate prediction of suicide in real-world contexts is given a great deal of attention in mental health services, despite the fact that current scientific knowledge and best practice guidelines in this area highlight that it is unlikely to be a good basis on which to provide access to treatment. It is our view that we have a good enough understanding of the common conditions people who struggle with suicidal distress experience and energy is better directed at acting to reduce exposure to these conditions and providing treatment for those who seek it. Blueprints for successful suicide prevention exist. If we lessen the focus on prediction, we will have greater resources to focus on treatment and prevention.

Validation of a brief tool to assess and monitor suicidal ideation: The Youth Suicide Ideation Screen (YSIS-3)

BACKGROUND

. Suicidal ideation is common in young people. Assessment and monitoring can help to understand its dynamic nature and inform treatment planning.

AIMS

. The aims were to evaluate psychometric properties of a brief screening tool - the Youth Suicide Ideation Screen-3 item (YSIS-3) and determine its correlation with the Suicidal Ideation Question-Junior (SIQ-JR) and measures of depressive and anxiety symptoms a.

METHOD

. Cronbach's alpha (α) was used to evaluate internal consistency of the YSIS-3 in 1107 young people. Convergent validity was evaluated using network analysis based on individual item polychoric correlations. Structural equation modelling was used to understand latent constructs; pearson product moment correlations to validate the integrity of the underlying construct. and two-way mixed Intraclass Correlation Coefficient to examine longitudinal stability and Cohen's d to assess sensitivity to change.

RESULTS

. The YSIS-3 was found to have internal consistency, convergent validity and criteria validity almost identical to the 15-item SIQ-JR. There was a high correlation (0.91) between the latent factor underpinning YSIS-3 and SIQ-JR. The YSIS-3 was more sensitive to change among those presenting with suicidal ideation at baseline.

CONCLUSIONS

. The YSIS-3 is a valid measure for the assessment and monitoring of suicidal ideation, and is sensitive to change. This brief measure can contribute to regular monitoring of the presence and nature of suicidal ideation, which when included in comprehensive assessment, will inform the clinical management of those at risk of suicide.
