In vitro differentiation of CD14 cells from osteopetrotic subjects: contrasting phenotypes with TCIRG1, CLCN7, and attachment defects.

UNLABELLED: We studied osteoclastic differentiation from normal and osteopetrotic human CD14 cells in vitro. Defects in acid transport, organic matrix removal, and cell fusion with deficient attachment were found. Analysis of genotypes showed that TCIRG1 anomalies correlated with acid transport defects, but surprisingly, organic matrix removal failure correlated with CLCN7 defects; an attachment defect had normal TCIRG1 and CLCN7. INTRODUCTION: Osteopetrotic subjects usually have normal macrophage activity, and despite identification of genetic defects associated with osteopetrosis, the specific developmental and biochemical defects in most cases are unclear. Indeed, patients with identical genotypes often have different clinical courses. We classified defects in osteoclast differentiation in vitro using four osteopetrotic subjects without immune or platelet defects, three of them severe infantile cases, compared with normals. MATERIALS AND METHODS: Osteoclast differentiation used isolated CD14 cells; results were correlated with independent analysis of two key genes, CLCN7 and TCIRG1. CD14 cell attachment and cell surface markers and extent of differentiation in RANKL and colony-stimulating factor (CSF)-1 were studied using acid secretion, bone pitting, enzyme, and attachment proteins assays. RESULTS AND CONCLUSIONS: CD14 cells from all subjects had similar lysosomal and nonspecific esterase activity. With the exception of cells from one osteopetrotic subject, CD14 cells from osteopetrotic and control monocytes attached similarly to bone or tissue culture substrate. Cells from one osteopetrotic subject, with normal CLCN7 and TCIRG1, did not attach to bone, did not multinucleate, and formed no podosomes or actin rings in RANKL and CSF-1. Attachment defects are described in osteopetrosis, most commonly mild osteopetrosis with Glantzman's thrombasthenia. However, this case, with abnormal integrin alphavbeta3 aggregates and no osteoclasts, seems to be unique. Two subjects were compound heterozygotes for TCIRG1 defects; both had CD14 cells that attached to bone but did not acidify attachments; cell fusion and attachment occurred, however, in RANKL and CSF-1. This is consistent with TCIRG1, essential for H+-ATPase assembly at the ruffled border. A compound heterozygote for CLCN7 defects had CD14 cells that fused in vitro, attached to bone, and secreted acid, TRACP, and cathepsin K. However, lacunae were shallow and retained demineralized matrix. This suggests that CLCN7 may not limit H+-ATPase activity as hypothesized, but may be involved in control of organic matrix degradation or removal.

Effect of locally delivered doxycycline hyclate on human fibroblast attachment to subgingival calculus.

BACKGROUND: Clinical studies using locally applied doxycycline hyclate (DHV) have demonstrated significant probing depth reduction and gain in clinical attachment as a monotherapy without scaling and root planing. The mechanism for this attachment level gain to the non-root planed tooth is not understood. The purpose of this study was to investigate the effect of locally applied doxycycline hyclate on human gingival fibroblast attachment to subgingival calculus on contaminated root surfaces. METHODS: Two separate experiments were performed, both on subgingival calculus. In experiment 1, teeth with subgingival calculus were treated with either doxcycycline hyclate in bioabsorbable vehicle (DHV) or with vehicle control (VC) in vivo. In experiment 2, teeth with subgingival calculus were treated with DHV, VC, scaling and root planing (SRP), or no treatment in vitro. The amount of cell attachment to calculus-covered root surfaces was quantitatively compared using a fluorescent dye assay and epifluorescence microscope. Values for cell attachment are presented as the mean standard deviation of the mean. The data were evaluated using Student t test. RESULTS: In both experiments, there was no statistically significant difference in fibroblast attachment in the DHV, VC, or no treatment groups (P >0.05). The SRP group showed significantly more cellular attachment to tooth surfaces formerly covered by subgingival calculus than all other groups (P <0.001). In general, more cells attached to cementum than to calculus. Root chips that showed no attachment to the subgingival calculus also had no cells attached to the adjacent cemental root surface. CONCLUSION: The addition of doxycycline hyclate in a bioabsorbable vehicle used as a locally delivered drug did not enhance the initial cellular attachment of human gingival fibroblasts to subgingival calculus or contaminated root surfaces.

Influence of catfish skin mucus on trisodium phosphate inactivation of attached Salmonella Typhimurium, Edwardsiella tarda, and Listeria monocytogenes.

This study examined the antimicrobial effectiveness of trisodium phosphate (TSP) on Edwardsiella tarda, Listeria monocytogenes, and Salmonella Typhimurium attached to catfish skin with and without mucus. Salmonella Typhimurium and E. tarda attached more readily to catfish skin than did L monocytogenes. At high inoculum levels (10(7) CFU/ml), TSP treatments (at 2 to 6%) for 10 min reduced bacterial counts of E. tarda by >2.5 to >3.3 log10 CFU per skin sample for firmly attached cells and by 3.5 to 3.6 log10 CFU per skin sample for loosely attached cells. Counts of L. monocytogenes declined by 0.6 to >1.8 log10 CFU per skin sample for firmly attached cells and by 1.2 to 2.2 log10 CFU per skin sample for loosely attached cells. Counts of Salmonella Typhimurium were reduced by 3.6 to >3.8 log10 CFU per skin sample for firmly attached cells and by 3.5 to >3.8 log10 CFU per skin sample for loosely attached cells. Overall, counts of firmly attached bacteria on TSP-treated skins with mucus were higher than counts on skin without mucus. Firmly attached L. monocytogenes was more resistant to TSP than was firmly attached Salmonella Typhimurium or E. tarda. The presence of mucus on skins slightly decreased the antimicrobial effect of TSP Significant (P < 0.05) reduction in the numbers of all three bacteria can be achieved by treatment with 6% TSP for 10 min.

Glycosaminoglycans and the substrate attachment of murine myeloma, 3T3, and cutaneous fibrosarcoma cells.

The attachment of murine myeloma, 3T3, and cutaneous fibrosarcoma cells to substrates of either fibronectin, type I collagen, or two types of tissue culture plastic was examined in the presence and absence of specific exogenous glycosaminoglycans. Fibrosarcoma and 3T3 cells were found to be nondiscriminatory with respect to their avidity of attachment to substrates of either of the proteins or of conventional tissue culture plastic, whereas the myeloma cells attached significantly less well to a substrate of collagen than to the other two matrices. On tissue culture plastic and collagen the fibrosarcoma cells attached more rapidly than did the other two cell types. Selective and partial inhibition of cell attachment to type I collagen, and, to a lesser extent, fibronectin, occurred upon preincubating these substrates with the sulfated glycosaminoglycans, heparin and heparan sulfate, at concentrations of 1 to 100 micrograms/ml; for 3T3 cells heparin was significantly more inhibitory (mean maximal inhibition of approximately 40%) than were two heparan sulfate fractions. Attachment of fibrosarcoma and 3T3 cells to a nitrogenated tissue culture plastic surface with a net positive charge (Primaria) was nearly 50% inhibited by heparin at the higher concentration and to a lesser extent by the two heparin sulfate fractions. Myeloma cell attachment to this same substrate was inhibited, to a lesser degree, by all three sulfated glycosaminoglycans. Hyaluronic acid, dermatan sulfate, and chondroitin 6-sulfate were inactive in our attachment assays. We suggest that the functional role of glycosaminoglycans in substrate attachment may vary depending on the cell type and the matrix involved in the specific interaction. In particular, the net charge of the substrate appears to be an important factor, and on positively charged surfaces these substances may serve a greater function. However, since nearly complete abrogation of cell attachment should have been achievable by some of the exogenous preparations if cell surface sulfated glycosaminoglycans were to comprise the major cellular binding sites for matrices, we conclude that it is unlikely that these complex polysaccharides function as the principal determinant of simple cell attachment.

Fibronectin mediates cell attachment to C1q: a mechanism for the localization of fibrosis in inflammatory disease.

Chronic inflammatory processes frequently lead to the abnormal replacement of normal tissue elements by increased numbers of fibroblasts and fibrous connective tissue, i.e., fibrosis. Since the growth of fibroblasts requires that these cells be attached to an extracellular support, the current study was designed to determine if the interaction between the fibroblast attachment factor fibronectin and the C1q component of complement could support fibroblast attachment and growth and thus could form a basis for the attachment of fibroblasts in abnormal tissue locations in those inflammatory states where C1q is bound. Fibronectin purified from human plasma supported attachment of both Chinese hamster ovary cells and of normal fetal lung fibroblasts (HFL-1) to C1q coated substrates. The attachment activity was approximately twice that of attachment to collagen, and was specific, as no attachment occurred to albumin coated substrates. Cells attached to C1q substrates demonstrated characteristic 'spreading' similar to those on collagen. Moreover, the C1q substrate resembled collagen in its ability to support fibroblast growth. Further, the ability of the interaction between C1q and fibronectin to mediate attachment of fibroblasts to immune complexes was demonstrated by the formation of fibroblast-red blood cell-immune complex rosettes, a process that was dependent on both fibronectin and C1q. Thus, the interaction between fibronectin and C1q could serve as the basis for fibroblast attachment and growth in abnormal tissue sites where immune complexes are formed and could be a contributing factor to the development of fibrosis.

Inhibition of Salmonella typhimurium attachment to chicken cecal mucus by intestinal isolates of Enterobacteriaceae and lactobacilli.

The ability of selected strains of Enterobacteriaceae or lactobacilli isolated from the intestines of adult chickens to inhibit in vitro attachment of Salmonella typhimurium 3333/O to cecal mucus in the presence or absence of D-mannose was determined. Attachment in the absence of mannose was reduced by prior exposure of mucus to cultures of two isolates of Enterobacteriaceae, an Escherichia coli and a Hafnia alvei strain, but not to a third isolate, an Enterobacter agglomerans strain. Attachment of S. typhimurium was not inhibited when mannose was present in the blocking or attachment step. Formation of fimbriae by the two inhibitory Enterobacteriaceae strains and the S. typhimurium strain, as indicated by titers of mannose-sensitive hemagglutination of guinea pig erythrocytes was optimal in Z biphasic medium (consisting of tryptone, yeast extract, dextrose, and NaCl) incubated anaerobically at 42 C. Fimbriae of each of three strains prepared from these cultures also inhibited attachment. These are characteristics consistent with attachment and inhibition of attachment mediated by a mannose-sensitive adhesin associated with type 1 fimbriae on bacterial cells of Enterobacteriaceae strains. Attachment in the presence of mannose was significantly reduced by prior exposure of mucus to cultures of a Lactobacillus salivarius strain and a Lactobacillus delbrueckii delbrueckii strain but not to a strain of Lactobacillus for which the species had not been determined. Washed cells or spent culture supernatant fluid from brain-heart infusion broth, Z broth, or Z biphasic cultures of the inhibitory strains of lactobacilli incubated at 37 or 42 C inhibited this form of attachment. Of 27 intestinal isolates of Enterobacteriaceae and 21 of lactobacilli, the lactobacilli strains were generally more hydrophobic than the Enterobacteriaceae as determined by adherence to hexadecane. The lactobacilli isolates did not agglutinate guinea pig erythrocytes. The data suggest more than one mechanism for mediating attachment of inhibitory bacterial strains and for subsequent attachment of S. typhimurium.

Formation and expression of filial attachment in rhesus monkeys raised with living and inanimate mother substitutes.

The formation and expression of filial attachment was investigated in rhesus monkeys raised with dogs or inanimate mother substitutes in a longitudinal study spanning the first 4 years of life. At 2 months monkeys were identified within each rearing group as strongly attached or weakly attached, as measured by proximity, contact and clinging to the mother substitute in the living cage and in a novel room, and by differences in levels of distress vocalization and heart rate when they were alone and in the presence of the substitute mother in a novel room. By 4 months, all monkeys were attached, and the strongly attached and weakly attached monkeys of the first age-period were no longer distinguishable on any measure. The attachment was specific to the substitute mother. It was not exclusive, however, inasmuch as similar responses were elicited by a stranger of the same type as the substitute mother, although the stranger was less effective. The attachment figure was also influential when it could be seen but not touched. Evidence of attachment to the substitute mothers persisted until the end of testing at 44 months. Comparison of rearing groups support the hypothesis that the principal effect of living and inanimate mother substitutes is on responsiveness, rather than on the attachment process per se.

Adult attachment style. I: Its relationship to clinical depression.

BACKGROUND: Although there are an increasing number of studies showing an association of adult attachment style to depressive disorder, such studies have rarely utilised epidemiological approaches with large community-based series and have relied heavily on brief self-report measurement of both attachment style and symptoms. The result is a wide inconsistency in the type of insecure style shown to relate to disorder. The present study examined adult attachment style in a high-risk community sample of women in relation to clinical depression. It utilised an interview measure of adult attachment which allowed for an assessment of both type of attachment style and the degree of insecurity of attachment. A companion paper examines its relationship with other depressive-vulnerability (Bifulco et al. 2002). METHOD: Two hundred and twenty-two high-risk and 80 comparison women were selected from questionnaire screenings of London GP patient lists and intensively interviewed. A global scale of attachment style based on supportive relationships (with partner and very close others) together with attitudes to support-seeking, derived the four styles paralleling those from self-report attachment assessments (Secure, Enmeshed, Fearful, Avoidant). In order to additionally reflect hostility in the scheme, the Avoidant category was subdivided into 'Angry-dismissive' and 'Withdrawn'. The degree to which attitudes and behaviour within such styles were dysfunctional ('non-standard') was also assessed. Attachment style was examined in relation to clinical depression in a 12-month period. For a third of the series this was examined prospectively to new onset of disorder. RESULTS: The presence of any insecure style was significantly related to 12-month depression. However, when controls were made for depressive symptomatology at interview, only the 'non-standard' levels of Enmeshed, Fearful or Angry-dismissive styles related to disorder. Withdrawn-avoidance was not significantly related to disorder. CONCLUSION: The relationship of attachment style to clinical depression is increased by differentiating the degree of insecurity of style and differentiating hostile and non-hostile avoidance.

Further evidence for the role of the dopamine D4 receptor (DRD4) gene in attachment disorganization: interaction of the exon III 48-bp repeat and the -521 C/T promoter polymorphisms.

In non-clinical low-risk populations 15% of infants show disorganized attachment behavior(1,2) with their caregivers in the Strange Situation,(3) a mildly stressful laboratory procedure testing infants' ability to cope with separation anxiety. Disorganization of early attachment has been primarily ascribed to inadequate parenting,(2,4,5) and has been associated with childhood behavior problems(6,7)and adolescent psychopathological tendencies.(5) We have recently reported an association between the DRD4 exon III 48 basepair repeat polymorphism and disorganization of infants' attachment behavior towards their mother in a low-social-risk group of 1-year-old infants:(8) the risk for disorganized attachment among infants carrying the 7-repeat allele was fourfold. Here we report further evidence for the involvement of the dopamine D4 receptor gene in attachment disorganization. The same group of infants was genotyped for the functional -521 C/T single nucleotide polymorphism (SNP) in the upstream regulatory region of the DRD4 gene(9) in order to test the association with attachment disorganization both alone and in interaction with the DRD4 exon III 7-repeat allele. While the -521 C/T genotype itself had no effect on attachment status (chi(2) = 0.41, df = 2, P = 0.82), there was an interaction between the structural 48-bp repeat polymorphism and the -521 C/T promoter polymorphism: the association between disorganized attachment and the 7-repeat allele was enhanced in the presence of the -521 T allele (chi(2) = 6.61 and 6.67, df = 1, P < 0.025 for CT and TT genotypes, respectively). In the presence of both risk alleles the odds ratio for disorganized attachment increased tenfold. This result supports our previous postulation that the DRD4 gene plays a role in the development of attachment behavior in low-risk, non-clinical populations.

A comparison of two measures to assess adult attachment.

The purpose of this study was to determine the relationship between two different approaches to the assessment of adult attachment. The approaches were C. Hazan and P. R. Shaver's (1987) categorization of three attachment styles and the dimensional system of the Reciprocal Attachment Questionnaire (RAQ; M. West & A. Sheldon-Keller, 1992). Participants were 196 (72 men and 124 women) respondents to a community survey. Multiple regression results showed that the three attachment groups differed significantly on three dimensions of the RAQ: feared loss of the attachment figure, perceived availability of the attachment figure, and use of the attachment figure. In addition, men and women differed significantly on use of the attachment figure, independent of their attachment style. The results indicate that the two approaches to the assessment of adult attachment are interrelated in meaningful ways.

Attachment theory, ageing and dementia: a review of the literature.

The following review draws together recent theoretical contributions and research findings highlighting the pertinence of attachment issues for older adults. Beginning with a brief overview of the principles of attachment theory, the paper proceeds to illustrate that attachment remains a key feature of relationships throughout the life cycle. Research findings suggest that past and present secure attachment relationships function as a protective resource in later life and preliminary studies highlight the continuing salience of parents as attachment figures for older adults. Particular attention is given to the significance of attachment theory in thinking about the subjective experiences of people with dementia, for whom unwilling separation and disruption of attachment bonds can be common themes. Research indicates the frequent occurrence of attachment behaviours and parent fixation amongst people with dementia living in residential care. Pre-morbid attachment style has been shown to interact with emotional and behavioural expression during the course of dementia. Clinical applications of attachment theory in dementia care are discussed and initial evidence for the effectiveness of Simulated Presence Therapy is provided. Methodological issues raised by the review are considered, together with suggestions for future research.

Attachment in deaf mothers and their children.

In attachment research, there has been a growing interest in how adults conceptualize their relationships with their own parents as well as in the transmission of attachment status from parent to child and the variables that influence that transmission. The primary goal of the present study was to examine the transmission of attachment from deaf mother to child. Adult Attachment Interviews were collected on 32 deaf women and Strange Situation Procedure data were obtained from their children. While the distribution of deaf mother attachment classifications was similar to that found with hearing samples, the concordance between mother and child in terms of attachment status was lower than in hearing samples. Having a deaf parent did not affect a deaf adult's attachment status. Post hoc analyses suggested a trend towards a dismissing stance in attachment relationships. Results are discussed in terms of variables affecting attachment status as well as the transmission of attachment.

Attachment in mothers with anxiety disorders and their children.

OBJECTIVE: This study examined adult attachment in mothers diagnosed with anxiety disorders and child-mother attachment in their children. METHOD: Eighteen mothers with Axis I anxiety disorders completed the Adult Attachment Interview and standardized questionnaires. These mothers and their preschool children (n = 20) then participated in the Strange Situation Procedure. RESULTS: All mothers were classified as nonautonomous with respect to attachment, with 78% judged unresolved. When those judged unresolved were reassigned to their alternate categories, the proportion of nonautonomous mothers was 61%. Eighty percent of the children were classified as insecurely attached, with 65% judged disorganized. When those judged disorganized were reassigned to their alternate categories, the proportion of insecurely attached children was 55%. Sixty-five percent of the children matched their mother's attachment classification. Mothers of securely attached children reported fewer recent life events, fewer depressive symptoms, and a greater sense of parenting competence than mothers of insecurely attached children. CONCLUSIONS: These results suggest that attachment measures can be applied to anxious populations. The high rate of insecurity among offspring of anxious mothers indicates a need for longitudinal studies of these children.

Attachment and psychosomatic medicine: developmental contributions to stress and disease.

OBJECTIVE: The object of this study was to evaluate the evidence linking attachment insecurity to illness. Attachment theory describes lifelong patterns of response to threat that are learned in the interaction between an infant and his or her primary caregiver. Despite its biopsychosocial domain, attachment theory has only recently been applied to psychosomatic medicine. METHOD: MEDLINE and PsychInfo databases were searched from 1966 to 2000 for English language papers with key words "attachment" and "object relations." Papers and their cited references were reviewed if they were directly related to physical illness, symptoms, or physiology. A hypothetical causal model was developed. RESULTS: Direct and indirect evidence from survey studies supports an association between attachment insecurity and disease. Animal studies and human experiments suggest that attachment contributes to individual differences in physiological stress response. There is also less robust support for insecure attachment leading to symptom reporting and to more frequent health risk behaviors, especially substance use and treatment nonadherence. Evidence supports the prediction from attachment theory that the benefits of social support derive more from attachment relationships than nonattachment relationships. CONCLUSIONS: Although the available data are suggestive rather than conclusive, the data can be organized into a model that describe attachment insecurity leading to disease risk through three mechanisms. These are increased susceptibility to stress, increased use of external regulators of affect, and altered help-seeking behavior. This model warrants further prospective investigation.

Adult social attachment disturbance is related to childhood maltreatment and current symptoms in borderline personality disorder.

We characterized borderline personality disorder (BPD) along two fundamental dimensions of adult social attachment and evaluated attachment associations with childhood maltreatment and current symptoms using self-report measures in 40 outpatients with DSM-IV BPD. The BPD group had significantly greater dimensional attachment impairment and rate of fearful attachment type compared with a healthy control group. Among BPD subjects, dimensional attachment-anxiety was specifically associated with sexual abuse, whereas attachment-avoidance was associated with all five maltreatment types. The two attachment dimensions showed divergent associations with current interpersonal problems, impulsivity subtypes and mood symptoms. We conclude that (1) BPD is characterized by adult attachment disturbance; (2) these attachment problems are strongly related to childhood maltreatment, and to current interpersonal problems and clinical symptoms that are considered core features of BPD; and (3) the diverse problems of BPD patients may arise from two basic mechanisms, each tied to a different type of attachment disturbance, developmental history, and clinical outcome.

Attachment level changes in destructive periodontal diseases.

The present communication attempts to summarize some of the features of attachment loss which are of interest to the clinician and the statistician analyzing data from clinical trials. These include the measurements employed to detect changes in attachment level, the nature of the destructive disease process and the effects of therapy on the attachment level measurements. Although there are several difficulties associated with the attachment level measurement, at the present time it appears to be the best estimator of periodontal attachment available. The overall standard deviation of this measurement in greater than 46,000 replicate measurements at periodontal sites in 58 subjects was 0.78 mm (range 0.4 to 1.2 mm). In the periodontally healthy subject, the length of the attachment measured around 28 teeth is approximately 700 mm. Therefore, there are approximately 1400 adjacent points along the periodontal attachment where a measurement could be made using a periodontal probe with a 0.5 mm diameter tip. If 6 measurements were recorded per tooth, then approximately 12% of the possible probable points would be evaluated. Recent data indicate that destructive periodontal diseases progress with acute bursts of activity rather than as slowly progressive, continual processes. Such findings suggest new models of attachment loss progression. In one likely model, destructive periodontal diseases would progress by asynchronous bursts of activity at individual sites which occur with greater frequency during a finite period of time in an individual's life. 3 major patterns of attachment loss could be distinguished when frequency distributions of attachment level measurements were constructed for 61 destructive periodontal disease subjects. Pattern I (30 subjects) exhibited a bimodal distribution with localized destruction occurring at less than 34% of sites. Pattern II (14 subjects) exhibited more widespread disease (greater than 33% of sites affected) with a trimodal frequency distribution. Pattern III (17 subjects) exhibited a unimodal distribution in which virtually all sites were affected. The proportions of Fusobacterium nucleatum, Streptococcus intermedius and Eikenella corrodens in subgingival plaque samples were significantly elevated in sites of subjects with patterns II and III (the widespread disease groups). Bacteroides intermedius, Streptococcus uberis and Actinobacillus actinomycetemcomitans were elevated in sampled sites of localized disease subjects (pattern I). The effects of therapy by Widman flap surgery and systemic tetracycline were examined by several statistical analyses.(ABSTRACT TRUNCATED AT 400 WORDS)

Automatic activation of attachment-related goals.

When people encounter threats, their attachment systems are activated and they become motivated to seek protection and support through proximity to their attachment figures. Theoretically, therefore, mental representations of attachment figures should be associated with goals related to attaining proximity and safety. The present studies explore this idea by examining the effects of a person's chronic attachment style and exposure to a particular attachment figure's name on the automatic activation of attachment-related goals. Studies 1 and 2 examine effects of exposure to the name of a security-providing attachment figure on willingness to self-disclose and seek support (two behaviors related to gaining proximity). Study 3 examines how exposure to names of different relationship partners (with whom a participant has felt secure, anxious, or avoidant) affects the mental accessibility of attachment-related goal words. Taken together, the studies support the idea that mental representations of attachment figures are associated with attachment-related goals.

Attachment as an organizer of behavior: implications for substance abuse problems and willingness to seek treatment.

BACKGROUND: Attachment theory allows specific predictions about the role of attachment representations in organizing behavior. Insecure attachment is hypothesized to predict maladaptive emotional regulation whereas secure attachment is hypothesized to predict adaptive emotional regulation. In this paper, we test specific hypotheses about the role of attachment representations in substance abuse/dependence and treatment participation. Based on theory, we expect divergence between levels of maladaptive functioning and adaptive methods of regulating negative emotions. METHODS: Participants for this study consist of a sample of adoptees participating in an ongoing longitudinal adoption study (n = 208). The Semi-Structured Assessment of the Genetics of Alcohol-II 41 was used to determine lifetime substance abuse/dependence and treatment participation. Attachment representations were derived by the Adult Attachment Interview [AAI; 16]. We constructed a prior contrasts reflecting theoretical predictions for the association between attachment representations, substance abuse/dependence and treatment participation. RESULTS: Logistic regression was used to test our hypotheses. As predicted, individuals classified as dismissing, preoccupied or earned-secure reported the highest rates of substance abuse/dependence. Individuals classified as dismissing reported significantly lower rates of treatment participation despite their high rates of substance abuse/dependence. As expected, the continuous-secure group reported lowest rates of both substance abuse/dependence and treatment participation. CONCLUSION: The findings from this study identify attachment representations as an influential factor in understanding the divergence between problematic substance use and treatment utilization. The findings further imply that treatment may need to take attachment representations into account to promote successful recovery.
