Conflicted control systems: the neural architecture of trauma

The Psychological Pathway to Suicide Attempts: A Strategy of Control Without Awareness

Objectives

This paper aims to identify potential areas for refinement in existing theoretical models of suicide, and introduce a new integrative theoretical framework for understanding suicide, that could inform such refinements.

Methods

Literature on existing theoretical models of suicide and how they contribute to understanding psychological processes involved in suicide was evaluated in a narrative review. This involved identifying psychological processes associated with suicide. Current understanding of these processes is discussed, and suggestions for integration of the existing literature are offered.

Results

Existing approaches to understanding suicide have advanced the current knowledge of suicide in various ways. They have guided valuable research in the following areas: motivations for suicide and the psychological distress which influences suicide attempts; ambivalence about suicide; suicidal individuals’ focus of attention; and ways in which individuals who contemplate suicide differ from individuals who attempt suicide. We outline a new theoretical framework as a means to integrating all of these concepts into the three principles of control, conflict, and awareness. Within this framework, suicide is regarded as occurring due to a long standing conflict between an individual’s personal goals, culminating in an episode of acute loss of control. The new framework posits that the individual then strives to regain control through the means of suicide because of a narrowed awareness of consequences of their actions on other valued goals. This psychological mechanism of limited awareness is posited to be the common pathway by which individuals make a suicide attempt, regardless of which risk factors are present.

Conclusion

This article introduces a theoretical framework that generates several hypotheses for future research, and focuses on psychological processes occurring during immediate crisis. One of the key hypotheses resulting from our predictions on how individuals progress from contemplating to attempting suicide will be tested in an ongoing program of research: Individuals who attempt suicide have a significantly reduced awareness of consequences of suicide, which would negatively impact on their important life goals, values, principles, or ideals, compared to individuals who contemplate suicide. Therapy guided by the new framework may be more flexible, immediate, and client-focused than other therapies for suicidal individuals.

Advancing nursing practice for improved health outcomes using the principles of perceptual control theory

This article describes how an empirically supported theory of human behaviour, perceptual control theory, can be used to advance nursing practice and improve health outcomes for people who are accessing nursing care. Nursing often takes a pragmatic approach to the delivery of care, with an emphasis on doing what appears to work. This focus on pragmatism can sometimes take precedence over any consideration of the underlying theoretical assumptions that inform decisions to take one particular approach over another or the mechanisms through which nursing interventions have their effects. For nursing to develop as a profession, there needs to be an increased focus on the core principles that underpin the delivery of care. In addition to understanding what works, nurses must develop their understanding of how and why particular approaches work or do not work. Understanding the fundamental principles that underpin nurses' actions will lead to more efficient and effective approaches to the delivery of nursing care. It will also enable nurses to maximize those elements of their practice that are most beneficial for people and minimize other activities that either have little effect or actually lead to worse outcomes. In this article, we will propose that the phenomenon of control is fundamental to human health. Perceptual control theory provides a coherent theoretical framework that enables us to understand the phenomenon of control through a functional model of human behaviour. People are healthy when their neurochemical, physiological, biological, psychological and social states are all controlled satisfactorily. We will explain the implications of understanding health as control throughout the paper. From this perspective, we will argue that the aim of nurses and nursing should be to support people to maintain or recover control over those aspects of their lives that are important and meaningful to them.

What is the relationship between post-traumatic stress disorder, extreme appraisals of internal state and symptoms in bipolar disorder?

BACKGROUND

It is important to understand the factors associated with more severe mood symptoms in bipolar disorder. The integrative cognitive model of bipolar disorder proposes that extreme appraisals of changes to internal states maintain and exacerbate mood symptoms.

AIMS

The current study aimed to investigate if post-traumatic stress disorder (PTSD) is related to current depressive and manic bipolar symptoms, and whether this relationship is mediated by appraisals of internal state.

METHOD

Participants with bipolar disorder (n = 82) from a randomized controlled trial of cognitive therapy for bipolar disorder (the TEAMS trial) completed self-reported questionnaires assessing appraisals of internal state, generalized anxiety symptoms, and self-reported and observer-rated depressive and manic symptoms. Clinical interviews assessed PTSD co-morbidity.

RESULTS

Participants with bipolar and co-morbid PTSD (n = 27) had higher depressive symptoms and more conflicting appraisals than those without PTSD. Regression analyses found PTSD to be associated with depressive symptoms but not manic symptoms. Conflicting appraisals were found to be associated only with manic symptoms meaning that the planned mediation analysis could not be completed.

CONCLUSIONS

Findings provide partial support for the integrative cognitive model of bipolar disorder and highlight the need for transdiagnostic treatments in bipolar disorder due to the prevalence and impact of trauma and co-morbidity. Working on trauma experiences in therapy may impact on depressive symptoms for those with bipolar disorder and co-morbid PTSD.

Psychological treatments for schizophrenia spectrum disorder: What is around the corner?

The evidence base for cognitive-behavioural therapy (CBT), family therapy, psychoeducation and cognitive remediation as adjuncts to antipsychotic medication in the treatment of schizophrenia is well established. It is, however, clear that the moderate effect size of the best researched of these treatments (CBT) compared with treatment as usual reduces to small when compared with an active psychological treatment. It would seem that many different psychosocial interventions de liver benefit in schizophrenia. We are now at a stage in their development when new treatments are being energetically piloted and combination treatments tested. This article outlines the most promising of these new interventions and attempts to answer the crucial question as to their differential effects on different psychotic presentations.

Learning Objectives

• Be aware of the most promising new psychosocial treatments for schizophrenia

• Learn the key elements of each intervention

• Understand which of these approaches might be best suited to particular presentations of schizophrenia spectrum disorder

What is distressing about auditory verbal hallucinations? The contribution of goal interference and goal facilitation

OBJECTIVES

Distressing and pleasant/positive voices (auditory verbal hallucinations) are common in both clinical and non-clinical voice-hearers. Identifying factors that contribute to emotional reactions to voices is essential for developing effective psychological interventions. Several theories propose that facilitation and interference with personal goals are important predictors of distress and well-being. This study examined whether voice-related distress is related to the degree to which voices interfere with personal goals, and whether pleasantness of voices is influenced by the extent to which they facilitate goals.

DESIGN

Cross-sectional with clinical and non-clinical voice-hearers.

METHOD

Twenty-two clinical and 18 non-clinical voice-hearers completed interviews and self-report measures assessing (1) personal goals, (2) content, characteristics, and affective reactions to voices, and (3) ratings of the extent to which voices facilitated and/or interfered with achievement of important personal goals.

RESULTS

Affective reactions were strongly correlated with measures of goal interference and goal facilitation. Regression analyses revealed that these associations remained significant when controlling for important covariates (e.g., participant grouping; content, frequency and duration of voices). Goal interference was specifically associated with distress, whereas goal facilitation specifically predicted perceived pleasantness of voices.

CONCLUSIONS

This study provides a novel perspective on the factors that might contribute to distress in people who hear voices. The findings suggest that perceived impact of voices on valued personal goals may be an important contributor of voice-related distress. We propose that clinical assessments, formulations, and interventions could benefit from the careful analysis of the perceived impact of voices on goals.

PRACTITIONER POINTS

These findings suggest that variability in voice-related distress is closely linked to the perceived impact of voices on personal goals. These strong effects observed highlight the importance of considering the role of personal goals in future research on the psychological mechanisms leading to distress associated with voice hearing. Psychological assessments may benefit from the careful exploration of the impact of voice hearing on valued goals, and interventions promoting control over personal goals may be explored as treatment options for clients with distressing voices.

The Take Control Course: Conceptual Rationale for the Development of a Transdiagnostic Group for Common Mental Health Problems

BACKGROUND

Increasingly, research supports the utility of a transdiagnostic understanding of psychopathology. However, there is no consensus regarding the theoretical approach that best explains this. Transdiagnostic interventions can offer service delivery advantages; this is explored in the current review, focusing on group modalities and primary care settings.

OBJECTIVE

This review seeks to explore whether a Perceptual Control Theory (PCT) explanation of psychopathology across disorders is a valid one. Further, this review illustrates the process of developing a novel transdiagnostic intervention (Take Control Course; TCC) from a PCT theory of functioning.

METHOD

Narrative review.

RESULTS AND CONCLUSIONS

Considerable evidence supports key tenets of PCT. Further, PCT offers a novel perspective regarding the mechanisms by which a number of familiar techniques, such as exposure and awareness, are effective. However, additional research is required to directly test the relative contribution of some PCT mechanisms predicted to underlie psychopathology. Directions for future research are considered.
