Abstract
OBJECTIVE The purpose of this study was to investigate how locus of control, coping strategies, emotion regulation strategies and social support affect posttraumatic growth. METHODS A cross-sectional study design was adopted. A convenience sample of 540 patients with lung cancer was recruited from November 2016 to July 2017 at two tertiary grade A hospitals in China. The participants completed a series of questionnaires. Structural equation modelling was used to explore the effects of psychosocial factors on posttraumatic growth. RESULTS Social support had a direct positive effect on posttraumatic growth (β = 0.318, SE = 0.071, BC 95% CI = 0.252/0.390), and it also had indirect effects on posttraumatic growth (β = 0.112, SE = 0.023, BC 95%CI = 0.088/0.135) through mediating psychological factors. Coping strategies and the cognitive reappraisal emotion regulation strategy were the main mediating variables, explaining approximately 73.1% of the indirect effect between social support and posttraumatic growth. CONCLUSIONS Our study suggests that Chinese lung cancer survivors can show relatively high posttraumatic growth. There are many mediating paths between social support and posttraumatic growth. These results may help healthcare professionals to identify the psychosocial factors that may benefit lung cancer patients and develop interventions to promote posttraumatic growth.

Schmidt SJ, Schultze-Lutter F, Bendall S, Groth N, Michel C, Inderbitzin N, Schimmelmann BG, Hubl D, Nelson B. Mediators Linking Childhood Adversities and Trauma to Suicidality in Individuals at Risk for Psychosis. Front Psychiatry 2017; 8:242. [PMID: 29249990 PMCID: PMC5715383 DOI: 10.3389/fpsyt.2017.00242] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Accepted: 11/06/2017] [Indexed: 12/29/2022] Open
Abstract
Suicidality is highly prevalent in patients at clinical high risk (CHR) for psychosis. Childhood adversities and trauma are generally predictive of suicidality. However, the differential effects of adversity/trauma-domains and CHR-criteria, i.e., ultra-high risk and basic symptom criteria, on suicidality remain unclear. Furthermore, the underlying mechanisms and, thus, worthwhile targets for suicide-prevention are still poorly understood. Therefore, structural equation modeling was used to test theory-driven models in 73 CHR-patients. Mediators were psychological variables, i.e., beliefs about one's own competencies as well as the controllability of events and coping styles. In addition, symptomatic variables (depressiveness, basic symptoms, attenuated psychotic symptoms) were hypothesized to mediate the effect of psychological mediators on suicidality as the final outcome variable. Results showed two independent pathways. In the first pathway, emotional and sexual but not physical adversity/trauma was associated with suicidality, which was mediated by dysfunctional competence/control beliefs, a lack of positive coping-strategies and depressiveness. In the second pathway, cognitive basic symptoms but not attenuated psychotic symptoms mediated the relationship between trauma/adversity and suicidality. CHR-patients are, thus, particularly prone to suicidality if adversity/trauma is followed by the development of depressiveness. Regarding the second pathway, this is the first study showing that adversity/trauma led to suicidality through an increased risk for psychosis as indicated by cognitive basic symptoms. As insight is generally associated with suicidality, this may explain why self-experienced basic symptoms increase the risk for it. Consequently, these mediators should be monitored regularly and targeted by integrated interventions as early as possible to enhance resilience against suicidality.

[PMID: 27632064 DOI: 10.1016/j.cpr.2016.08.003] [Citation(s) in RCA: 126] [Impact Index Per Article: 15.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 06/17/2016] [Accepted: 08/30/2016] [Indexed: 01/14/2023]
Abstract
Traumatic life events have been robustly associated with various psychosis outcomes, including increased risk of psychotic disorders, the prodrome of psychosis, and dimensional measures of psychotic symptoms, such as attenuated positive psychotic symptoms. However, trauma exposure has been linked to various mental disorders; therefore, the specificity of trauma exposure to psychosis remains unclear. This review focuses on two understudied areas of the trauma and psychosis literature: 1) the specificity between trauma and psychosis in relation to other disorders that often result post-trauma, and 2) proposed mechanisms that uniquely link trauma to psychosis. We begin by discussing the underlying connection between trauma exposure and the entire psychosis spectrum with a focus on the influence of trauma type and specific psychotic symptoms. We then consider how the principles of multifinality and equifinality can be useful in elucidating the trauma-psychosis relationship versus the trauma-other disorder relationship. Next, we discuss several cognitive and neurobiological mechanisms that might uniquely account for the association between trauma and psychosis, as well as the role of gender. Lastly, we review important methodological issues that complicate the research on trauma and psychosis, ending with clinical implications for the field.
