Positive psychiatry: A clinical handbook.
By Jeste, Dilip V. (Ed); Palmer, Barton W. (Ed)
2015.
As detailed throughout this volume, a growing body of research strongly suggests that positive psychosocial factors (PPSFs) such as resilience, optimism, and social engagement are associated with objectively measurable better outcomes, including lower morbidity and greater longevity, as well as with equally important subjective positive outcomes such as well-being. Rather surprisingly, most of the existing research on positive traits, positive social factors, and other positive outcomes has been conducted outside the field of psychiatry and, perhaps of even greater importance, has had relatively little influence on everyday psychiatric practice. Thus, despite the progressive accumulation of empirical data supporting the critical role of PPSFs in overall mental and physical health, clinical psychiatric practice and training remain primarily restricted to diagnosis and treatment of mental illnesses, whereas psychiatric research focuses mainly on elucidating the underlying psychopathology and neuropathology and ameliorative interventions to treat and prevent relapses of mental illnesses. Psychiatrists have generally considered positive mental health constructs to be too vague for routine clinical practice or serious scientific inquiry within the field of psychiatry. The premise of this volume is that the time has come to make these positive mental health concepts a central component of psychiatric practice, education, and research.

Hope theory.

Hope, as defined by Snyder (1994), is a set of goal-relevant thoughts that propel us toward important outcomes and the resultant positive emotions in our lives. Hope is positively related to positive affect, meaning in life, life satisfaction, academic and athletic achievement, and coping with, adversity, and is negatively associated with negative affect, psychopathology, and other markers of distress. For many, the lessons of hope are learned early in life, and success in important life domains maintains and increases hope over the lifespan. There is also evidence that hope can be learned and strengthened through interventions targeted at augmenting agency and pathways thinking. Although there is a strong hope literature base, we are in need of more studies that provide information about the temporal unfolding of the hope model and also parse out the differential relations of hope with other positive psychology constructs. Additionally, we would benefit from a continued examination of how the component parts of hope (i.e., goals, pathways thinking, agency thinking). transact with one another and predict the benefits associated with hope. In summary, there have been important advances in the theoretical and empirical underpinnings of hope in the last two decades, and we are excited to see where new investigations will lead us in the decades to come.

Personal peacefulness: Psychological perspectives.
By Floody, Dale R.
Sims, Gregory K. (Ed); Nelson, Linden L. (Ed); Puopolo, Mindy R. (Ed), (2014). Personal peacefulness: Psychological perspectives. Peace psychology book series. Vol 20, (pp. 107-133). New York, NY, US: Springer Science + Business Media, ix, 285 pp.
Serenity can be thought of as a personal and unique way of living which includes behavioral and cognitive components that are associated with feeling calm, peaceful, and untroubled. Synonyms for serenity may include inner peacefulness, peace of mind, tranquility, contentment, equanimity, and "cool." Somewhat surprisingly, there is very little consideration of serenity in all of psychology. Historically, psychology has focused on negative behaviors (especially aggression, psychopathology, and mental retardation), but recently there has been an explosion of interest in a more positive approach. "Positive psychology" (or at least the phrase) was launched in the year 2000, and it rapidly became very popular, but proponents also became preoccupied with the study of happiness and hedonic well-being. The endless pursuit of happiness often led to unrealistic expectations and use of prescription medications for understandable anxiety or depression in the face of life events. An understanding of factors related to serenity and inner peace would be more likely to address the underlying causes of anxiety, depression, and dissatisfaction with life. Further, Cohrs et al. (in press) have argued that positive psychology's emphasis on happiness (notably positive experiences, personal well-being, and personal resilience) may contribute to intrapersonal peace, but focusing on internal issues could also just as well have negative consequences for others (including other nations). Serenity, on the other hand, may include being more positive toward others and promoting social justice. (PsycINFO Database Record (c) 2014 APA, all rights reserved)
Meaning sensitive psychotherapy: Binding clinical, existential, and positive psychological perspectives.
Batthyany, Alexander (Ed); Russo-Netzer, Pninit (Ed), (2014). Meaning in positive and existential psychology. , (pp. 269-289). New York, NY, US: Springer Science + Business Media, xvii, 467 pp.
This chapter provides an overview of the meaning sensitive psychotherapy. Meaning in life, defined as a sense of coherence and purpose that has personal, spiritual/self-transcendent, and implicit/normative-ethical components, plays an integral role in promoting psychological health, whether viewed from a clinical, existential, or positive psychological perspective. Clinical research focuses on the impact that one's ability to make meaningful assumptions about self and world has on levels of anxiety, particularly posttraumatic stress disorder (PTSD) symptoms, as well as the link between alleviation of depressive symptoms and a sense of purpose motivating activation of meaningful behaviors. Positive psychological research emphasizes the resiliency against psychopathology and positive emotions experienced by individuals with a strong sense of meaning in life. The existential tradition deals with the intrinsic value in facing the tension between absurdity and malevolence we encounter in the world and the pervasiveness and intricacy of our encounters with coherence and virtue. Insofar as the concept of meaning in life winds its way from symptom focused, clinical concerns, through aspects of resiliency and positive emotions, and finally to concerns that transcend the dichotomy between positive and negative states, sensitivity to this concept results in a well-rounded and farsighted framework for the conduct of psychotherapy. This framework promotes the alleviation of acute distress, remediation of vulnerabilities for such distress, enhancement of positive well-being beyond the mere absence of or resiliency against psychopathology, and contact with frequently unnoticed or avoided aspects of existence that stir self-transcendent motivation and emotion. This chapter reviews research findings and theory informing a meaning sensitive approach to psychological well-being, details a framework for applying these findings in the practice of psychotherapy, and, where appropriate, suggests useful research directions.
