Originally formulated to understand the recurrence of depressive disorders, the stress generation hypothesis has recently been applied in research on anxiety and externalizing disorders. Results from these investigations, in combination with findings of extensive comorbidity between depression and other mental disorders, suggest the need for an expansion of stress generation models to include the stress generating effects of transdiagnostic pathology as well as those of specific syndromes. Employing latent variable modeling techniques to parse the general and specific elements of commonly co-occurring Axis I syndromes, the current study examined the associations of transdiagnostic internalizing and externalizing dimensions with stressful life events over time. Analyses revealed that, after adjusting for the covariation between the dimensions, internalizing was a significant predictor of interpersonal dependent stress, whereas externalizing was a significant predictor of noninterpersonal dependent stress. Neither latent dimension was associated with the occurrence of independent, or fateful, stressful life events. At the syndrome level, once variance due to the internalizing factor was partialed out, unipolar depression contributed incrementally to the generation of interpersonal dependent stress. In contrast, the presence of panic disorder produced a "stress inhibition" effect, predicting reduced exposure to interpersonal dependent stress. Additionally, dysthymia was associated with an excess of noninterpersonal dependent stress. The latent variable modeling framework used here is discussed in terms of its potential as an integrative model for stress generation research.
"Although this is the first attempt to our knowledge to integrate these components of these two cognitive models of suicide, our model is compatible with several preexisting frameworks. For example, our model is compatible with newer transdiagnostic models of psychopathology   that stress the importance of integrating distal and proximal risk factors into one model. Our model is also compatible with other integrated models of suicide in Fig. 3. Path model testing negative cognitive style as a mediator of the relationship between IPT variables and suicidal ideation.Note. "
[Show abstract][Hide abstract] ABSTRACT: Given that suicide is a leading cause of death worldwide, there has been considerable research on theories of suicide risk. Despite the volume of such research, each theory is largely investigated in isolation and there has been little attempt to integrate them. Thus, the goal of the present study is to integrate two theories of suicide risk, Alloy and Abramson's hopelessness theory of suicide (HT) and Joiner's interpersonal psychological theory of suicide (IPTS), into one mediational model where the effects of the risk associated with the HT variables (i.e., a negative cognitive style) on suicidal ideation are transmitted by the IPTS (i.e., perceived burdensomeness and thwarted belonging) variables. Participants were 245 young adults with elevated levels of depressive symptoms who completed self-report measures of suicide risk at baseline and a measure of suicidal ideation eight weeks later. The results of a mediated model supported our hypothesis. The effects of the HT variables on suicidal ideation were mediated by the IPTS variables. Furthermore, results did not support the reverse model, suggesting specificity of the direction of our hypotheses. These findings imply that there may be merit in attempting to integrate theories of suicide risk rather than studying them in isolation.
[Show abstract][Hide abstract] ABSTRACT: This study investigated factors associated with social isolation in parents of children with hemangiomas. Eighty-one parents completed questionnaires assessing their emotional distress, social isolation, and coping styles. To explore the relationships between these variables, a path analysis was used to test a model in which clinical characteristics of hemangiomas and parents' coping strategies do not have direct effects on their social isolation but indirect effects via their emotional distress. Bootstrapping was used to assess indirect effects. Time since onset and lesional complications had positive direct effects on parents' social isolation. Lesional visibility and emotion-focused coping had negative indirect effects on parents' social isolation via their emotional distress, while problem-focused coping showed a positive indirect effect. These findings may have implications for clinicians managing parents of children with hemangiomas.

[Show abstract][Hide abstract] ABSTRACT: Individuals with borderline personality disorder (BPD) often experience stressful life events at a higher frequency than those without BPD. It is less clear what specific types of events are involved in this effect, and it has not been determined whether some features of BPD are more important than others in accounting for this effect. The latter issue is important in light of the heterogeneous nature of this diagnostic construct. These issues were examined in a large, representative community sample of men and women, ages 55-64. Ten Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev., DSM-IV-TR, Washington, DC, American Psychiatric Association, 2000) personality disorders were assessed at baseline using the Structured Interview for DSM-IV Personality: SIDP-IV (B. Pfohl, N. Blum, & M. Zimmerman, 1997, Washington, DC, American Psychiatric Press). Life events were measured at three sequential assessments following baseline at 6-month (N = 1,294), 12-month (N = 1,070), and 18-month (N = 837) follow-ups. Stressful life events were identified using a self-report questionnaire (LTE-Q; List of Threatening Experiences Questionnaire: A subset of prescribed life events with considerable long-term contextual threat by T. Brugha, C. Bebbington, P. Tennant, and J. Hurry, 1985, Psychological Medicine, Vol. 15, pp. 189-194.) followed by a telephone interview. Only borderline personality pathology was related to an increase in the frequency of interpersonal stressful life events. Three specific symptoms of BPD were largely responsible for this connection: unstable interpersonal relationships, impulsivity, and chronic feelings of emptiness (negative association). Symptoms of avoidant and schizoid personality disorders were associated with a reduced number of stressful life events that are considered to be outside a person's control (e.g., serious illness, injury, or death of a loved one). None of the personality disorders predicted an increase in the number of stressful financial events (e.g., major financial crisis). These findings suggest that, as individuals approach later life, certain features of BPD continue to serve as important risk factors for stressful life events of an interpersonal nature.
