Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations.

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.

Predictors of the generation of episodic stress: a longitudinal study of late adolescent women.

The effects of depression and Axis I comorbidity on subsequent self-generated life stress were examined in a longitudinal sample of 134 late adolescent women. The results indicated that specific forms of psychopathology constitute a risk factor for future self-generated episodic stress, even when controlling for prior chronic stress. Comorbid depression had a particularly salient effect in the prediction of stress related to interpersonal conflicts. The effects of family psychopathology and sociotropy were mediated through participant psychiatric status, whereas autonomy made an independent contribution to the prediction of episodic stress. These results support C. Hammen's (1991b) stress generation model in a community sample, demonstrating how individuals with depression play a role in the creation of stress, and also refine prior work by showing that only the comorbid form of depression is associated with subsequent conflict-related stress.

Families as systems.

In this chapter, we discuss theoretical and conceptual models that use an organismic or systems metaphor for understanding families. We suggest that such theories are important for stimulating new research and organizing existing data, and that advances in these theories over the past few decades have expanded the potential for understanding child development, as well as adult adaptation and the development of close relationships. These paradigms follow from models that view development as resulting from the transactional regulatory processes of dynamic systems. Such models are helpful for considering multiple influences on development and adaptation and have implications for the design of effective interventions. We focus on the specifics of systems theories as applied to families, and the research generated by or consistent with these views. Our review is not exhaustive; rather, we intend to give a sense of the direction of this work and its importance for the understanding of development and adaptation.

The relationship between attachment cognitions and psychological adjustment in late adolescent women.

This longitudinal study of 137 female high school seniors investigated the relationship of attachment cognitions, current psychological functioning, and psychological functioning 12 months later. Attachment cognitions, assessed with the Revised Adult Attachment Scale and the Inventory of Parent and Peer Attachment, were significantly associated with current symptomatology. The Revised Adult Attachment Scale, in interaction with initial symptomatology, predicted depression, substance abuse, eating disorders, and personality disorders 12 months later. The Inventory of Parent and Peer Attachment parent subscales predicted eating disorder and personality disorder symptomatology, whereas the peer subscales predicted substance abuse, eating disorder, and personality disorder symptomatology.

Poor interpersonal problem solving as a mechanism of stress generation in depression among adolescent women.

The authors examined C. Hammen's (1991) model of stress generation in depression and the role of interpersonal problem-solving strategies (IPS) in the stress generation process in a longitudinal sample of 140 young women who entered the study at ages 17-18. Structural equation modeling was used to test a model in which IPS and subsequent interpersonal stress mediated the relationship between initial and later depressive symptoms. Results supported the main prediction of the stress generation model: Interpersonal stress mediated the relationship between initial and later depressive symptoms. In addition, IPS predicted interpersonal stress. However, no association was found between depressive symptoms and IPS. An alternative model in which IPS moderated the relationship between stress and depressive symptoms was tested; it was not supported.

Interpersonal attachment cognitions and prediction of symptomatic responses to interpersonal stress.

The authors tested a cognitive-interpersonal hypothesis of depression by examining the role of interpersonal cognitions in the prediction of depression associated with interpersonal stressors. A measure of adult attachment assessed interpersonal cognitions about ability to be close to others and to depend on others and anxiety about rejection and abandonment. Participants were women who had recently graduated from high school; they were followed for 1 year with extensive interview evaluation of life events, depression, and other symptomatology. Generally, cognitions, interpersonal events, and their interactions contributed to the prediction of interview-assessed depressive symptoms, but the effects were not specific to depression and predicted general symptomatology measured by diagnostic interviews as well, and results also varied by attachment subscale. Results were discussed in terms of a developmental psychopathology approach to disorders in young women.

Enumeration of sublethally heated staphylococci in some dried foods.

The effect of 45 substances to restore the salt tolerance of sublethally heat-injured Staphylococcus aureus was tested. Sodium pyruvate, yeast extract, L-histine, casitone (Difco), adenosine triphosphate, and acetylphosphate were effective. For enumeration a repair medium was first used, containing sodium pyruvate and penicillin in 1% skim milk. This step was followed by counting on Baird-Parker agar with penicillinase. This method was selective; fewer than 100 staphylococci/g food could be enumerated and it gave counts about 8 times higher than the method of Giolitti and Cantoni used as a five-tube most probable number technique. Heat injury sensitized S. aureus to polymyxin.
