Thematic and content analyses are qualitative methods that serve different research purposes. Thematic analysis provides an interpretation of participants' meanings, while content analysis is a direct representation of participants' responses. These methods provide two ways of understanding meanings and experiences and provide important knowledge in a mental health context.

Bipolar disorder (BD) is a major mood disorder that is characterized by manic and depressive symptoms which fluctuate in severity and over time. The affective burden of the illness is compounded by cognitive, psychosocial, and occupational dysfunction, along with increased rates of suicide, medical comorbidity, and premature mortality. [1][2][3][4][5][6][7] Current guidelines for the management of BD include treatments that are limited by suboptimal efficacy rates, medication intolerance, delayed onset of action, iatrogenic mood switches, and variable patient acceptability. There is a pressing public health need for measures to combat these shortcomings. The fields of chronobiology and chronotherapy offer alternative treatment strategies which may address these limitations. The primary aim of this project was to systematically review efficacy and tolerability evidence of the major chronotherapies for BD and propose practice recommendations based on this review. This commences with a brief introduction to chronobiology to provide a rudimentary overview of the basic science which underlies this field of treatment. | Introduction to the circadian systemThe basic science of chronobiology is the study of biological rhythms, biological timekeeping systems, and their effects on human health and disease. 8 The human time-keeping system is a strongly conserved, phylogenetically ancient, hierarchically organized, and open neurobiological network. It evolved to enable organisms to anticipate and coordinate their internal physiology

The majority of patients with bipolar disorder have onset prior to twenty years with early onset associated with increased impairment. Despite this, little attention has been given to the psychosocial developmental impact of this disorder. This qualitative study explored the impact of having bipolar disorder on the development of a sense of self and identity. Key findings from this qualitative study identified that for these participants, bipolar disorder had a significant impact in the area of self and identity development. Bipolar disorder created experiences of confusion, contradiction, and self doubt which made it difficult for these participants to establish continuity in their sense of self. Their lives were characterized by disruption and discontinuity and by external definitions of self based on their illness. Developing a more integrated self and identity was deemed possible through self-acceptance and incorporating different aspects of themselves. These findings would suggest that it is critical to view bipolar disorder within a psychosocial developmental framework and consider the impact on the development of self and identity. A focus on the specific areas of impact and targeting interventions that facilitate acceptance and integration thus promoting self and identity development would be recommended.

IPSRT and SSC used as an adjunct to pharmacotherapy appear to be effective in reducing depressive and manic symptoms and improving social functioning in adolescents and young adults with bipolar disorder and high rates of comorbidity. Identifying effective treatments that particularly address depressive symptoms is important in reducing the burden of bipolar disorder.

We replicated a slowing in alternation rate in some bipolar disorder participants. The alternation rate was not affected by depressed mood or any of the other factors explored, which supports views of binocular rivalry rates as a trait marker in bipolar disorder.

Bipolar disorder is a chronic and recurrent disorder with fluctuating symptoms. Few patients with bipolar disorder experience a simple trajectory of clear-cut episodes, with recovery typically occurring slowly over time. The chronic and disabling course of the disorder has a marked impact on the person's functioning and relationships with others. The objectives of this study were to investigate the impact of bipolar disorder on the lives of people diagnosed with this disorder. The method used was a general inductive qualitative approach. Twenty-one participants were interviewed between 2008 and 2009 about how they had experienced the impact of bipolar disorder. The interviews were audio-taped and transcribed. The core theme that emerged was the participants were feeling out of control. Their own reactions and the reactions of others to the symptoms of bipolar disorder contributed to this core theme. The core theme was constituted by feeling overwhelmed, a loss of autonomy and felling flawed. Mental health nurses can help facilitate a sense of personal control for people with bipolar disorder by exploring what the symptoms mean for that person and implementing strategies to manage the symptoms, address social stigma and facilitate active involvement in treatment.
