Abstract

The Adult Attachment Interview (AAI) is a widely used measure in developmental science that assesses adults' current states of mind regarding early attachment-related experiences with their primary caregivers. The standard system for coding the AAI recommends classifying individuals categorically as having an autonomous, dismissing, preoccupied, or unresolved attachment state of mind. However, previous factor and taxometric analyses suggest that: (a) adults' attachment states of mind are captured by two weakly correlated factors reflecting adults' dismissing and preoccupied states of mind and (b) individual differences on these factors are continuously rather than categorically distributed. The current study revisited these suggestions about the latent structure of AAI scales by leveraging individual participant data from 40 studies (N = 3,218), with a particular focus on the controversial observation from prior factor analytic work that indicators of preoccupied states of mind and indicators of unresolved states of mind about loss and trauma loaded on a common factor. Confirmatory factor analyses indicated that: (a) a 2-factor model with weakly correlated dismissing and preoccupied factors and (b) a 3-factor model that further distinguished unresolved from preoccupied states of mind were both compatible with the data. The preoccupied and unresolved factors in the 3-factor model were highly correlated. Taxometric analyses suggested that individual differences in dismissing, preoccupied, and unresolved states of mind were more consistent with a continuous than a categorical model. The importance of additional tests of predictive validity of the various models is emphasized.

Abstract

This article presents a strategy for the initial step of data harmonization in Individual Participant Data syntheses, i.e., making decisions as to which measures operationalize the constructs of interest - and which do not. This step is vital in the process of data harmonization, because a study can only be as good as its measures. If the construct validity of the measures is in question, study results are questionable as well. Our proposed strategy for data harmonization consists of three steps. First, a unitary construct is defined based on the existing literature, preferably on the theoretical framework surrounding the construct. Second, the various instruments used to measure the construct are evaluated as operationalizations of this construct, and retained or excluded based on this evaluation. Third, the scores of the included measures are recoded on the same metric. We illustrate the use of this method with three example constructs focal to the Collaboration on Attachment Transmission Synthesis (CATS) study: parental sensitivity, child temperament, and social support. This process description may aid researchers in their data pooling studies, filling a gap in the literature on the first step of data harmonization. • Data harmonization in studies using combined datasets is of vital importance for the validity of the study results. • We have developed and illustrated a strategy on how to define a unitary construct and evaluate whether instruments are operationalizations of this construct as the initial step in the harmonization process. • This strategy is a transferable and reproducible method to apply to the data harmonization process.

Abstract

Parents' attachment representations and child-parent attachment have been shown to be associated, but these associations vary across populations (Verhage et al., 2016). The current study examined whether ecological factors may explain variability in the strength of intergenerational transmission of attachment, using individual participant data (IPD) meta-analysis. Analyses on 4,396 parent-child dyads (58 studies, child age 11-96 months) revealed a combined effect size of r = .29. IPD meta-analyses revealed that effect sizes for the transmission of autonomous-secure representations to secure attachments were weaker under risk conditions and weaker in adolescent parent-child dyads, whereas transmission was stronger for older children. Findings support the ecological constraints hypothesis on attachment transmission. Implications for attachment theory and the use of IPD meta-analysis are discussed.

Abstract

Purpose: This cohort study investigated changes in physical activity, community mobility and social participation following the first-time purchase of a mobility scooter. Methods: A national sample of persons aged 65+ years was surveyed using customized semi-structured interviews that explored changes in physical activity via the International Physical Activity Questionnaire modified for the elderly, and community involvement. Participants were recruited at the point of purchase of their first mobility scooter, and interviewed at this time and again at 2 and 6 months post-purchase. Results: Eighteen participants (F = 10, M = 8) aged between 65 and 95 years were recruited. Physical activity levels remained unchanged in 12 participants, and declined by at least one category in five participants. All participants reported improvement to their self-perceived quality of life following acquisition of a mobility scooter. Participants did not access additional forms of physical activity, though nine reported increased social participation. At baseline, five participants stated that the scooter was used for journeys they formerly made by other motorized transport, and by the 6-month interview, this number had risen to 15 participants. Conclusions: It is unlikely that changes in physical activity were related to the ageing process given the relatively short time span of the study. Thus it can be inferred that participants viewed their mobility scooter as a vehicle for maintaining their lifestyle rather than as a means to seek out additional activities. Improvements to perceived quality of life may be attributed to continuing or furthering community and social engagement, and a sense of retained independence. An awareness of possible changes in physical activity associated with the purchase of a mobility scooter is needed. The purchase of a mobility scooter provides a viable means of transport to facilitate access to physical activity situations. Over-reliance on a mobility scooter has the potential to decrease health-related physical activity. The development and dissemination of a targeted health message about maintaining (or improving) physical activity levels is warranted to increase the awareness in this growing group of new, and current, mobility scooter riders in an increasingly ageing population.

15. A biopsychosocial understanding of lower back pain: Content analysis of online information.

Author

Black, N. M., Sullivan, S. J., and Mani, R.

Abstract

Objectives: (1) To develop a checklist to assess the representation of biopsychosocial lower back pain (LBP) online information; (2) to analyse publicly accessed online LBP information from a Google search for the degree that psychosocial contributors are described alongside the traditional biomedical approach to explaining LBP; (3) whether websites use information on pain biology to educate on LBP; (4) any inaccurate or false information regarding the mechanisms of LBP and; (5) the amount of websites certified by established benchmarks for quality health information.Materials and Methods: An online search was conducted using the Google search engines of six major English-speaking countries. Website content was analysed using three checklists developed for the purpose of this study - Biopsychosocial information categorisation checklist and scoring criteria; pain biology information checklist; and the inaccurate information checklist. Website quality was identified by the presence of an Health on the Net certification (HONcode).Results: Of the fifteen websites analysed, the content of 26.7% of websites was classified as 'biomedical', 60% 'limited psychosocial' and 13.3% 'reasonable psychosocial'; 20% included information on pain biology; 46.7% inaccurately implied pain to be equal to tissue damage and 46.7% implied pathways specific to pain transmission; 40% were HONcode certified.Conclusion: Online LBP information retrieved through a Google search has limited to no integration of psychosocial or pain biology information. The focus on tissue pathology is further supported by the inaccurate descriptions of pain as equal to tissue damage and as an input to the central nervous system (CNS). Online LBP information needs to be guided by criteria more sensitive to the psychosocial contributors to pain.Significance: The online LBP information retrieved from a Google search needs to be guided by information more sensitive to the psychosocial contributors to pain and disability. This study also highlights the presence of inaccurate information that implied pain as a measure of tissue damage or as an input to the nervous system. [ABSTRACT FROM AUTHOR]

36. Kinetic analysis of chemotactic peptide receptor modulation.

Author

Zigmond, S H, Sullivan, S J, and Lauffenburger, D A

Abstract

The dynamics of the chemotactic peptide receptor on rabbit peritoneal polymorphonuclear leucocytes were followed using the tritiated peptide N-formylnorleucylleucylphenylalanine (FNLLP). We have used a kinetic analysis to examine the possible interrelationships between receptor loss (down-regulation), receptor-mediated peptide uptake, and receptor recycling. We have previously demonstrated that cells incubated with FNLLP show a dose-dependent reduction in the number of receptors available on the surface. This receptor down-regulation is complete within 20 min and then the number of receptors available for binding remains at a plateau level. Peptide continues to be taken up in a receptor-mediated manner even after down-regulation is complete. If peptide is removed, receptor recovery occurs and does not require protein synthesis. In these studies we have investigated the kinetics of these processes. On the basis of this analysis, we propose that the plateau receptor level is a steady-state in which receptor internalization and return occur continuously. We demonstrate that the rate of receptor-mediated peptide uptake is approximately equal to the rate of receptor recovery measured after peptide removal. In addition, the rate of receptor recovery is proportional to the number of receptors missing from the surface, suggesting receptor recycling may be occurring.

37. Asymmetric distribution of the chemotactic peptide receptor on polymorphonuclear leukocytes.

Author

Sullivan, S J, Daukas, G, and Zigmond, S H

Abstract

The distribution of chemotactic peptide receptors on polymorphonuclear leukocytes (PMNs) was visualized using tritiated chemotactic peptide, N-formylmethionyl-leucylphenylalanine, coupled to hemocyanin (HY-FMLP). This probe was biologically active and the number of HY-FMLP molecules bound to the cell in a saturable manner corresponded closely to the number of peptide receptors characterized for rabbit peritoneal polymorphonuclear leukocytes (Sullivan, S. J., and S. H. Zigmond, 1980, J. Cell Biol., 85:703-711). Cells exhibiting locomotion have a polar morphology easily recognized in the scanning electron microscope. HY-FMLP bound to these cells was asymmetrically distributed with the highest density of HY-FMLP bound to the midregion of the cell. There were very few particles bound to the tail regions. The binding to the leading ruffles was variable but usually less than to the midregion. Addition of high concentrations of uncoupled FMLP eliminated HY-FMLP binding, confirming that the hemocyanin observed was a marker for the saturable chemotactic peptide receptor. The asymmetry in receptor distribution was seen on cells that had been stimulated by low concentrations of either FMLP or another chemotactic factor, leukotriene B4. Thus, peptide binding to the receptor was not required for the development of the asymmetric distribution. The low density of receptors in the tail region of the cell was consistent with the decreased responsiveness of the tail to chemotactic stimulation (Zigmond, S. H., H. I. Levitsky, and B. J. Kreel, 1981, J. Cell Biol., 89:585-592). The receptor asymmetry may contribute to the polar behavior exhibited by polymorphonuclear leukocytes and would be expected to quantitatively modify the directional information available to a cell in a gradient of chemotactic peptide.

38. Sensory adaptation of leukocytes to chemotactic peptides.

Author

Zigmond, S H and Sullivan, S J

Abstract

The morphology and behavior of polymorphonuclear leukocytes (PMNs) were studied after rapid changes in the concentration of a chemotactic factor N-formylnorleucylleucylphenylalanine (f-NorleuLeuPhe) (Schiffmann et al., 1975, Proc. Natl. Acad. Sci. U. S. A. 72:1059--1062). After an increase in peptide concentration, the cells round, form lamellipodia or ruffles over most of their surface, and stop locomotion. These changes are transient. After a delay, the cells, still in the presence of peptide, withdraw most of the ruffles and resume locomotion, forming ruffles only at their front. Cells repeat the transient generalized ruffling upon further increase in peptide concentration. The behavioral changes occur over the same dose range as binding to a saturable receptor. The duration of the transient response after a concentration increase is roughly proportional to the increase in the number of cell receptors occupied as a result of the concentration change. Decreasing the concentration of peptide causes the cells to round transiently and form blebs before they recommence locomotion. The transient nature of these aspects of the cell's responsiveness to chemotactic factors appears to be due to adaptation by the cells. The ability to adapt to the concentration of a chemotactic factor may be important in leukocyte chemotaxis.

39. The processing of receptor-bound [125I-Tyr11]somatostatin by RINm5F insulinoma cells.

Author

Sullivan, S J and Schonbrunn, A

Abstract

The peptide somatostatin (SRIF) is secreted by delta cells of the endocrine pancreas and inhibits the secretion of insulin from pancreatic beta cells. We have previously shown that [125I-Tyr11]SRIF binds to specific, high affinity receptors on RINm5F insulinoma cells and that these receptors mediate the action of SRIF to inhibit insulin release. In the present study we investigated the processing of receptor-bound [125I-Tyr11]SRIF in this clonal cell line. Surface-bound and internalized peptides were distinguished by the ability of an acid/salt solution (0.2 M acetic acid, 0.5 M NaCl, pH 2.5) to dissociate only exposed ligand-receptor complexes. Surprisingly, greater than 80% of saturably bound [125I-Tyr11]SRIF was removed by this acid wash independent of the time or temperature of the binding incubation. In contrast, the processing of receptor-bound [125I]EGF (epidermal growth factor) in RINm5F cells was markedly temperature-dependent. Although over 90% of saturably bound [125I]EGF was dissociated by acid after a 4 degrees C binding incubation, less than 10% was removed by acid treatment after 37 degrees C binding. The radioactivity released upon dissociation of receptor-bound [125I-Tyr11]SRIF was analyzed by high performance liquid chromatography and shown to consist of a mixture of intact peptide (40%) and [125I]tyrosine (60%). However, neither the rate of [125I-Tyr11]SRIF dissociation nor its degradation were affected by NH4Cl, methylamine, or leupeptin at concentrations which inhibited the lysosomal degradation of [125I] EGF. Of 11 other protease inhibitors tested, only the metalloendoprotease inhibitor, phosphoramidon, substantially reduced the degradation of receptor-bound [125I-Tyr11]SRIF. These data indicate that, unlike [125I] EGF, receptor-bound [125I-Tyr11]SRIF is not rapidly internalized by RINm5F cells and is degraded by a nonlysosomal process which may involve a metalloendoprotease.

40. Chemotactic peptide receptor modulation in polymorphonuclear leukocytes.

Author

Sullivan, S J and Zigmond, S H

Abstract

The binding of the chemotactic peptide N-formylnorleucylleucylphenylalanine (FNLLP) to its receptor on rabbit polymorphonuclear leukocytes (PMNs) modulates the number of available peptide receptors. Incubation with FNLLP decreases subsequent binding capacity, a phenomenon that has been termed receptor down regulation. Down regulation of the chemotactic peptide receptor is concentration dependent in both the rate and extent of receptor loss. The dose response parallels that of FNLLP binding to the recptor. The time-course is rapid; even at concentrations of FNLLP as low as 3 x 10(-9) M, the new equilibrium concentration of receptors is reached within 15 min. Down regulation is temperature dependent, but does occur even at 4 degrees C. Concomitant with down regulation, some of the peptide becomes irreversibly cell associated. At 4 degrees C, there is a small accumulation of nondissociable peptide that rapidly reaches a plateau. At higher temperatures, accumulation of nondissociable peptide continues after the rceptor number has reached equilibrium, and the amount accumulated can exceed the initial number of receptors by as much as 300%. The dose response of peptide uptake at 37 degrees C reflects that of binding, suggesting that it is receptor mediated. This uptake may occur via a pinocytosis mechanism. Although PMNs have not been considered to be pinocytic, the addition of FNLLP causes a fourfold stimulation of the rate of pinocytosis as measured by the uptake of [3H]sucrose.
