Aloneness and borderline psychopathology: the possible relevance of child development issues.

The experience of intense painful aloneness is a common event in the lives of borderline patients, especially those closer to the psychotic spectrum. This experience is defined as an intrinsic aspect of the borderline personality defect and consists of a relative or total inability to remember positive images or fantasies of sustaining people in the patient's present or past life, or being overwhelmed by negative memories and images of these people. The development of borderline aloneness is related to a possible developmental failure, defined by Piaget, Fraiberg, and A.-M. Sandler. These workers describe the child's development of object permanence and evocative memory capacity (Piaget's sensori-motor stage VI). We postulate that a major borderline vulnerability is the tenuous achievement of the capacity for affective object permanence and its regressive loss to recognition memory or earlier when under specific stresses. We relate our hypotheses to possible empathic parental failures during the substages of separation-individuation, especially the rapprochement sub-phase. The treatment implications of our formulations are discussed, with an emphasis on the clarification of the need for the therapist's availability and the use of transitional objects during times of the patient's loss of his affective cognitive capacities. These regressive experiences often emerge as a core transference manifestation during psychoanalytic therapy with borderline patients, and often become the basis of significant therapeutic work.

Assessing salivary cortisol in studies of child development.

In a series of studies, we evaluated the susceptibility of radioimmunoassays (RIA) for saliva cortisol to interference effects caused by oral stimulants used to facilitate saliva collection in studies with children. When added directly to saliva samples, oral stimulants (drink mix crystals) artificially inflated estimated cortisol concentrations. The magnitude of the interference effect was concentration-dependent and more pronounced for some stimulants and RIA procedures than for others. Analysis of samples collected using oral stimulants from child and adult participants confirmed stimulant interference as an extraneous source of variability in measured saliva cortisol. Associations between serum and saliva cortisol and between saliva cortisol and "behavioral" variables were attenuated by stimulant interference. A survey of six large child studies estimated interference effects, indexed by low sample pH, to be present in 14.7% of the 1,148 total saliva samples, or 2%-54% (M = 22%) of samples within each study. Recommendations to minimize the impact of stimulant interference in studies involving salivary cortisol in the context of child health and development are outlined.
