The treatment of depression in older adults in the primary care setting: an evidence-based review.

The objective of this study was to conduct an evidence-based review of treatments for depression in older adults in the primary care setting. A literature search was conducted using PsycINFO and Medline to identify relevant, English language studies published from January 1994 to April 2004 with samples aged 55 and older. Studies were required to be randomized controlled trials that compared psychosocial interventions conducted within the primary care setting with "usual care" conditions. Eight studies with older adult samples met inclusion criteria and were included in the review. Two treatment models were evident: Geriatric Evaluation Management (GEM) clinics and an approach labeled integrated health care models. Support was found for each model, with improvement in depressive symptoms and better outcomes than usual care; however, findings varied by depression severity, and interventions were difficult to compare. Further efforts to improve research and clinical care of depression in the primary care setting for older adults are needed. The authors recommend the use of interdisciplinary teams and more implementation of psychosocial treatments shown to be effective for older adults.     

The relation of sex-role self-concept and sex-role attitudes to the marital satisfaction and personal adjustment of dual-worker couples with preschool children

The present study was designed to investigate the relation of sex-role self-concept and sex-role attitudes to the marital satisfaction and personal adjustment of dual-worker couples with preschool children. One hundred husbands and wives completed an assessment package consisting of the Bem Sex Role Inventory, the Personal Attributes Questionnaire, the Attitudes Toward Women Scale, the Locke- Wallace Marital Adjustment Test, and the Profile of Mood States. As predicted, androgynous individuals reported the greatest levels of marital satisfaction and personal adjustment. This was true for both men and women and across occupational levels. In addition, congruence between spouses' sex-role attitudes was associated with greater marital satisfaction.The present study is based on a masters thesis by the first author under supervision of the second and third authors. The authors thank Manuel Barrera and Sandy Braver, who were very helpful committee members, and Larry Cooper and Clark C. Presson for their helpful comments.     

Catastrophe theory: A topological reconceptualization of sexual orientation

The classical model of sexual orientation as a continuum is examined and hypotheses regarding the sequential patterning of sexual partner choices are considered. Data are reviewed which suggest that these patterns are often discontinuous: shifts from one orientation to the other are observed without a transitional period and bisexuality is rare as a lifestyle in which contacts with both male and female partners are regular, concurrent, ongoing activities. Catastrophe theory, a mathematical model of discontinuity, is explained with the simple example of aggression in dogs and then the simple cusp catastrophe is applied as a starting place for this topological reconceptualization of sexual orientation. Behavioral predictions and implications for future research are discussed.     

Induction of depressed mood: a test of opponent-process theory

Solomon's (1980) opponent-process theory of acquired motivation has been used to explain many phenomena in which affective or hedonic contrasts appear to exist, but has not been applied to the induction of depressed mood. The purpose of this study, therefore, was to determine whether opponent-process theory can be applied to this area. Velten's (1968) mood-induction procedure was used and subjects were assigned either to a depression-induction condition or to one of two control groups. Self-report measures of depressed mood were taken before, during, and at several points after the mood induction. Results were not totally consistent with a rigorous set of criteria for supporting an opponent-process interpretation. This suggests that the opponent-process model may not be applicable to induced depressed mood. Possible weaknesses in the experimental design, along with implications for opponent-process theory, are discussed.     

Transients in “constant-current” generators

Some shock-generator circuits may deliver large transient surges at onset and termination. The sources of these surges are derivable from electromagnetic analysis of the circuits employed. Virtual elimination of the surges may be accomplished by a simple rearrangement of the switching portion of the circuit.
