Effect Of Air-Abrasion And Er:Yag Laser On The Bond Strength Between The Metal Housing Of An Overdenture Attachment System And The Hard Relining Material

Objective. This study investigated the effect of air-abrasion and erbium:yttrium-aluminum-garnet (Er:YAG) laser treatments on push-out bond strength (PBS) between hard relining material and metal housing of an overdenture attachment system. Material and Methods. A total of 36 metal housings were randomly divided into 3 subgroups according to surface pretreatments (n=12): Control (no surface treatment; C), air-abrasion (A), and Er:YAG laser (L). Surface roughness (Ra) of specimens was determined using a profilometer. One additional specimen per group was evaluated by scanning electron microscopy (SEM). The hard relining material was bonded to metal housings, and a PBS test was performed using a universal testing machine. Data were statistically analyzed using 1-way analysis of variance (ANOVA), Tukey’s honestly significant difference (HSD), and Tamhane’s T2 tests (α=.05). Results. C and L groups showed the lowest and highest Ra values, respectively. The mean Ra of the A group was statistically different from the mean values of the C and L groups (P<.001). The L group showed higher PBS values than the C group (P<.05), whereas the A group exhibited statistically similar PBS values to both C and L groups (P>.05). Conclusions. Air-abrasion did not significantly increase the bond strength between the metal housing and hard relining material. Er:YAG laser irradiation noticeably improved the PBS but caused surface microcracks.

Validating the caregiving experiences questionnaire (CEQ) in a Turkish setting: Understanding attachment and parental care in diverse contexts

Despite the universal significance of secure attachments, differences exist in parental responses to children’s signals of need across cultures. While much research has focused on Western countries, there is a growing recognition of the need to explore cultural variations in parental ideologies and caregiving practices. However, limited assessment tools exist for evaluating caregiving experiences, particularly in non-Western contexts. This present design study aims to explore the Turkish validity of the Caregiving Experiences Questionnaire (CEQ), specifically tailored to assess the self-reported caregiving experiences of parents with young children within the attachment system. The Turkish-CEQ was administered to 339 Turkish mothers with children attending preschools. Confirmatory Factor Analysis was employed to assess the congruence of the Turkish data. The results showed that the CEQ is a relevant construct in Turkish culture. The CEQ successfully adapted to Turkish, resulting in a questionnaire comprising 34 items organized into four factors namely maintaining warm parental bond, suffering from separation concerns, struggling with parenting challenges, and imposing emotional parentification on the child. The internal consistency of each factor demonstrates satisfactory reliability, with Cronbach Alpha coefficients ranging between 0.71 and 0.80. Finally, we assessed the criterion validity of the CEQ by examining its relationships with the Parental Burnout Assessment and Parenting Stress Scale. The results support the criterion validity of the Turkish-CEQ. The study provides Turkish researchers with a new instrument for assessing caregiving experiences and paves the way for future cross-cultural studies on caregiving experiences among parents from diverse backgrounds in Turkey.

Parasitoid attachment ability and the host surface wettability

Climbing animals such as geckos and arthropods developed astonishing adhesive mechanisms which are fundamental for their survival and represent valuable models for biomimetic purposes. A firm adhesion to the host surface, in order to successfully lay eggs is necessary for the reproduction of most parasitoid insects. In the present study, we performed a comparative investigation on the attachment ability of four parasitoid species (the egg parasitoid Anastatus bifasciatus (Eupelmidae), the aphid parasitoid Aphidius ervi (Braconidae), the fly pupal ectoparasitoid Muscidifurax raptorellus (Pteromalidae) and the pupal parasitoid of Drosophila Trichopria drosophilae (Diapriidae)) with hosts characterized by a surface having different wettability properties. The friction force measurements were performed on smooth artificial (glass) surfaces showing different contact angles of water. We found that attachment systems of parasitoid insects are tuned to match the wettability of the host surface. Sexual dimorphism in the attachment ability of some tested species has been also observed. The obtained results are probably related to different microstructure and chemical composition of the host surfaces and to different chemical composition of the parasitoid adhesive fluid. The data here presented can be interpreted as an adaptation, especially in the female, to the physicochemical properties of the host surface and contribute to shed light on the coevolutionary processes of parasitoid insects and their hosts.

Attachment and Political Personality are Heritable and Distinct Systems, and Both Share Genetics with Interpersonal Trust and Altruism

The attachment and caregiving domains maintain proximity and care-giving behavior between parents and offspring, in a way that has been argued to shape people’s mental models of how relationships work, resulting in secure, anxious or avoidant interpersonal styles in adulthood. Several theorists have suggested that the attachment system is closely connected to orientations and behaviors in social and political domains, which should be grounded in the same set of familial experiences as are the different attachment styles. We use a sample of Norwegian twins (N = 1987) to assess the genetic and environmental relationship between attachment, trust, altruism, right-wing authoritarianism (RWA), and social dominance orientation (SDO). Results indicate no shared environmental overlap between attachment and ideology, nor even between the attachment styles or between the ideological traits, challenging conventional wisdom in developmental, social, and political psychology. Rather, evidence supports two functionally distinct systems, one for navigating intimate relationships (attachment) and one for navigating social hierarchies (RWA/SDO), with genetic overlap between traits within each system, and two distinct genetic linkages to trust and altruism. This is counter-posed to theoretical perspectives that link attachment, ideology, and interpersonal orientations through early relational experiences.

A relational perspective on how and when follower attachment style impacts job performance: The moderating role of leader neuroticism

AbstractWe integrate insights from attachment theory and relational leadership to develop a novel interpersonal explanation of why, how and when followers' attachment anxiety and avoidance impact performance. Drawing on the attachment system dynamics model, we posit that attachment avoidance will be negatively related to LMX quality, whereas attachment anxiety will be positively related to LMX ambivalence. Furthermore, we predict that followers' anxious (and avoidant) attachment styles will interact with leader neuroticism leading to a hyperactivation (deactivation) of the attachment system, manifesting in greater LMX ambivalence (and lower LMX quality). Across three studies, we found consistent evidence for a positive relationship between follower attachment anxiety and LMX ambivalence, as well as an indirect effect between attachment anxiety and job performance. Leader neuroticism was especially likely to induce LMX ambivalence and, in turn, undermine job performance in anxiously attached followers. Attachment avoidance, although unaffected by leader neuroticism, was negatively related to LMX quality across all three studies and demonstrated an indirect effect on job performance in Study 3. Overall, our findings shed light on the unique explanatory power of relational mechanisms, beyond previously examined intrapersonal mechanisms, for understanding the attachment style–performance relationship as well as the role that leader characteristics play in triggering the attachment system in anxious followers.

Comparative analysis of the ultrastructure and adhesive secretion pathways of different smooth attachment pads of the stick insect Medauroidea extradentata (Phasmatodea).

The mechanism by which insects achieve attachment and locomotion across diverse substrates has long intrigued scientists, prompting extensive research on the functional morphology of attachment pads. In stick insects, attachment and locomotion are facilitated by two distinct types of smooth cuticular attachment pads: the primary adhesion force-generating arolium and the friction force-generating euplantulae. They are both supported by an adhesive secretion delivered into the interspace between the attachment pads and the substrate. In this study, we analysed and compared internal morphology, material composition and ultrastructure, as well as the transportation pathways in both adhesive organs in the stick insect Medauroidea extradentata using scanning electron microscopy, micro-computed tomography, light microscopy, and confocal laser scanning microscopy. Our observations revealed structural differences between both attachment pads, reflecting their distinct functionality. Furthermore, our results delineate a potential pathway for adhesive secretions, originating from exocrine epidermal cells and traversing various layers before reaching the surface. Within the attachment pad, the fluid may influence the viscoelastic properties of the pad and control the attachment/detachment process. Understanding the material composition of attachment pads and the distribution process of the adhesive secretion can potentially aid in the development of more effective artificial attachment systems.

The impact of chewing force simulation on stress distribution of implant retained mandibular overdenture with locator attachment system having matrix of PEEK versus nylon insert

The current study investigates the impact of chewing force simulation on stress strain distribution of Mandibular overdentures retained with locator attachment system having matrix of PEEK versus nylon insert. Twenty completely edentulous mandibular digitally printed models were fabricated with beds for two implants, which had been inserted in the estimated canine positions with two grooves mesial and distal at each implant site for the attachment of the strain gauges for each model. Nova loc group NLG with ten implant assisted mandibular complete overdentures were fabricated over ten printed models with nova loc attachments while locator group LG had ten implant assisted mandibular complete overdentures over ten printed models with locator attachments of same retaining force and geometric height. Bilateral vertical load was applied with a universal testing machine and strain induced to the implants was measured around the two implants medially and distally in each group using strain gauges pre & post one year simulated functional aging. Student t test was used for comparing the two types of attachments while paired t test was used for comparison of strain induced to the implants after one year of functional aging, with probability level p < 0.05 is considered statistically significant. Individual statistical analysis of the data revealed increase in the number of measured strains for both attachments which was statistically significant for locator. Comparing the two groups, significant increase for the locator attachment after one year simulated functional aging was detected compared to nova loc. Within the limitations of this study, one year simulated functional aging seems to cause disturbance in the load conveyed to the supporting structures of mandibular implant assisted overdenture retained with locator in contrast to nova loc that showed more resistance to aging process, thus nova loc attachment transmit less stresses than locator attachment to the surrounding implants supporting structures specially after time of service related to its combined materials superior physical properties.

A comparative evaluation of retention capacity of different dental implant supported overdenture attachment systems- An in vitro study

The most common way to treat full edentulism is with a complete denture. In the mandible as opposed to the maxilla, there is greater worry over the durability and retention of a traditional complete denture. The mandibular arch's decreased surface area for support and retention is the main cause of this. For a fully edentulous mandible, implant-supported overdentures are a reliable course of treatment.This in-vitro study aimed at comparing the retentive capacity of Ball, Locator and OT Equator Implant supported overdenture attachment system when subjected to 14600 cycles of insertion and de-insertion.Fifteen mandibular dentures were fabricated with heat polymerized polymethyl methacrylate resin to test the retentive capacity of Ball, Locator and OT Equator attachment system. Metal housing with retentive nylon caps were picked up in all the sample using cold cure acrylic resin. The samples were subjected to fatigue testing and only monodirectional force was applied. Ball, Locator and OT Equator attachment system sample were subjected to 14,600 insertion/ de insertion cycle on Universal Testing Machine and data was recorded and statistical analysis was done. All the three groups showed significant differences. The retentive capacity of the Ball attachments lasts longer than that of the Locator and Equator attachments. After ten years of use, All three systems continue to have clinically acceptable retention.

An easily attachable measurement system of joystick angle in a power wheelchair using IMUs for maneuvering logger

Monitoring joystick operations in power wheelchairs (PWCs) is promising for investigating user-wheelchair interaction and providing quantitative measures to assess the user’s driving performance. In this paper, an add-on measurement system, Power Wheelchair Maneuvering Logger (PWhML), is developed to provide an easy-to-implement and cost-effective solution for monitoring the user’s joystick operations in PWCs. The proposed system uses two compact inertial measurement units (IMUs), which are respectively attached to the joystick and wheelchair armrest for movement sensing. A coordinate transformation-based method is proposed to estimate the joystick operating angles using the acceleration data measured by the attached IMUs. The accuracy of the proposed method was thoroughly evaluated under different conditions. The evaluation trials in a stationary PWC reported a mean absolute error (MAE) of 0.59° in the forward/backward direction and 0.64° in the leftward/rightward direction, validating the established geometry model for coordinate transformation. The subsequent driving experiments on outdoor test courses demonstrated the effectiveness and robustness of the proposed method in various terrain conditions (MAE of less than 3°). A clustering analysis based on the t-distributed stochastic neighborhood embedding method correctly categorized different driving activities using the joystick operating angles measured by PWhML. These results indicate that integrating the developed PWhML into PWCs can facilitate a quantitative measurement of the user’s driving behavior, providing valuable insights to identify careless operation patterns and help PWC users to improve driving performance.

A comparative evaluation of masticatory load distribution in different types of prosthesis with varying number of implants: A FEM analysis

AimTo identify the optimal number and position of implants to reduce stress concentration on the implant, denture, and attachment system for sustaining an overdenture prosthesis. Materials and methodsBy incorporating one to eight indigenous implants with bar-type attachments, eight 3D finite element models of mandibular overdentures were created. All models received a 200 N vertical load, and the biomechanical characteristics of peri-implant bone were assessed. ResultThe study observed that with a vertical load of 200 N, the maximum equivalent stress around peri-implant tissue in all models was within the physiological tolerance threshold of bone. The von Mises stress values ranged from 116.18 MPa to 536.7 MPa. ConclusionThe three-implant-supported overdenture model revealed superior peri-implant stress, stability, cost-effectiveness, and hygiene maintenance outcomes. Placing a third implant in the mid-symphysis region may offer a practical solution to reduce rotations in two-implant-supported overdentures.

Trust-Based Relational Intervention® (TBRI®) Impact for Traumatized Children-Meaningful Change on Attachment Security and Mental Health after One Year.

Children from vulnerable backgrounds often have insecure attachment or disorganized attachment, which are related to psychological troubles, and such children need interventions to help them heal. The attachment system reorganizes in middle childhood, and other important adults play a considerable role in children's lives. Thus, it is essential to weigh the impact of psychosocial interventions, while the main focus of the intervention is the staff member's direct work with the child through a trusting relationship. The primary purpose of this study is to investigate whether children's attachment security and mental health outcomes change after participating in a trauma-informed, attachment-based, Trust-Based Relational Intervention (TBRI) provided in a daycare center. It was a case-series study involving twelve children aged 8-11 years. The child attachment interview (CAI), CBCL/6-18, TRF/6-18, and clinical interviews for parents and children were used, measuring the change between the TBRI implementation in the daycare center and after one year. For ten participants, we noticed an improvement in mental health; for seven participants, security scales improved; for two participants, their disorganized attachment changed into insecure-dismissing. We have preliminary evidence that vulnerable children may benefit in terms of attachment security and mental health from the trusting relationship that staff build using the TBRI.

COMPARATIVE ANALYSIS OF PROSTHETIC REHABILITATION OF PATIENTS WITH COMPLETELY EDENTULOUS JAWS USING DIFFERENT OPTIONS FOR IMPLANT- SUPPORTED STRUCTURES

Objectives: To conduct a comparative analysis the effectiveness of prosthetic rehabilitation of patients with completely edentulous jaws using various options for implant-supported structures. Materials and methods: We examined and carried out complex treatment with the installation of implants in 82 patients (56 to 73 aged) years with completely edentulous jaws. All patients underwent a clinical examination and using cone beam computed tomography (CBCT) analyzed of residual bone. Patients with edentulous were rehabilitated with three implant-supported prosthetic protocols. The patient was divided into 3 groups: 21 (1grup.) patients received removable overdenture supported by 4 implants using a bar system, 19 (2grup) patients received removable overdenture supported by 4 implants using rail system of attachments, 23 (3grup) patients received fixed restorations supported by 4 implants. Peri-implant marginal bone level (MBL), immediately (base line for comparison) and 1 year, 3 years, and 5 years after implant installation, compared with values at last follow-up. The method of questioning patients was used. The assessment was carried out using a point system: chewing efficiency, ease of care and use, stability of the dentures. Quality of life, assess used the Oral health-related quality of life the OHIP-G scale. Results: In clinical follow-up the implants showed no mobility, soreness or pain during function, patients had healthy soft tissues. For patients 1group MBL after 1 year 0.82 mm, after 3 years 1.23 mm, after 5 years was 1.46 mm. For patients 2group MBL after 1 year 0.84 mm, after 3 years 1.28 mm, after 5 years was 1.49 mm. For patients 3 group MBL after 1 year 0.91 mm, after 3 years 1.32 mm, after 5 years was 1.53mm. The patients were satisfied with the result of treatment using implants. Speech adaptation of patients with removable dentures, fixed implants, occurred within a week. 5-year implants cumulative survival rate 1group rates was 96.7%, 2 group was 97.2%, 3 group rates was 96,9%. The prosthesis cumulative survival rate 1group was 96.7%, 2 group was 97.4%, 3 group was 97,6%. Conclusion: Implant-supporting structures on implants, installed between the mental foramens, are a reliable and predictable method for patients with complete edentulous jaws and significant jaw resorption. This solution is a reliable alternative to bone grafting, demonstrating fewer complications, fewer additional surgical procedures, and demonstrating satisfactory long-term survival.

Evaluation of masticatory efficiency and OHRQoL in implant-retained overdenture with different numbers of implant in the edentulous mandible: a one-year follow-up prospective study

PurposeThe aim of this article is to evaluate to the masticatory function performance and Oral Health-related Quality of Life (OHRQoL) in implant-retained overdenture compared with different implant number placements in the edentulous mandible.MethodsFrom 2013 to 2015, each patients received 3 implants (iSy-Implant, Camlog, Wimsheim, Germany) in intraforaminal mandible (34, 41/31, 44). After operation, inserted implants were gradually loaded and incorporated into an overdenture with a self-aligning attachment system (Locator abutments) in 3 + 3 + 3 months. Five checked points were performed chewing cycle test with multicolored chewing gum and OHIP-G14 questionnaire and a sum score questionnaire as following: pre-operation, one implant load (41/31), two implants loaded (33,43), three implants loaded and 1-year follow up.ResultA total of 10 patients with 30 implants were placed, the survival rate of the implants was 100% within 1-year follow-up. Regarding the masticatory function analysis, for the higher number of chewing cycles, the higher mixing rate was observed. After 1 year, the inter-mixing rate without significant changes was found compared to the time after three implants were loaded with attachment system. The mean value of OHIP-G14 was 30.4 preoperatively, 21.1 after loading the first locator, 10.7 after loading two locator abutments, and 3.2 after loading all three locator abutments. After 1 year, OHIP-G14 was 2.6 without significantly changed. The mean of the sum score was 15.5 preoperatively, 27.8 after activation of the first locator, 39.4 after activation of two locators, 46.2 after activation of all three locators, and 47.3 after 1 year. An increase of 0.7 sum score units per time point was observed. No significance was detectable, analogous to OHIP-G14, compared to the time of activation of all three locator setups (p-value = 0.22).ConclusionsA significant improvement in masticatory function performance and OHRQoL was evaluated with the increasing number of implants with locator attachment in edentulous mandible. With the investigation of the OHIP-G14 and sum score, the results of patient report outcome might be associated with the increase in the number of implants.Graphical abstract

Influence of cladding attachment structural elements on the thermal performance of lightweight steel-framed walls

The thermal transmittance characteristics of the building envelope significantly influences the whole building energy performance. Lightweight steel framed (LSF) systems with cladding attached back to structures using thermal clips or bracket systems are widely used in heating dominated climates. Thermal bridging associated with the cladding structural elements that bypass the exterior insulation to attach the cladding cannot be avoided, but their impact can be significantly mitigated. This study investigates the thermal influence of a generic aluminum cladding attachment system that has varying levels of complexity associated with thermal breaks, and rail penetration into the insulation. A total of five configurations were assessed besides a reference configuration, which was devoid of any cladding attachment structure. Three-dimensional finite element software (HEAT3) and a small-scale calibrated hot box apparatus were employed to perform the analyses. The objectives were to show the influence of the cladding attachment elements and demonstrate the ability of hot-box measurements and numerical simulations to quantify the influence. Results show a small deviation between numerical simulations and experimental measurements, ranged between - 0.85% and 3.70%. The variations in thermal transmittances properties of the investigated wall assemblies are presented, which vary from 40% to 57% compared to the reference case. These findings highlight the significant influence of the structural elements that bypass exterior insulation and how small variations of the same system can impact the whole thermal performance. The heat loss through the cladding attachment structural elements, which bypass exterior insulation, can be reduced by using thermal breaks like neoprene spacers appropriately.

The influence of attachment style on support and feedback seeking and depression severity among mothers during the COVID-19 pandemic.

The ways that people seek support during times of stress influence their mental health outcomes, including depression. Insecure attachment is a risk factor for depression and may also interfere with adaptive support and feedback-seeking behaviour during stress. The purpose of the present study was to test theorized associations between insecure attachment, support and feedback seeking, and changes in depression symptoms over 1 year, in a sample of mothers of school-age children in the context of stress elicited by the COVID-19 pandemic. Participants (N = 70 mothers) completed self-report measures of anxious and avoidant attachment and depression severity at baseline in spring 2020 and then completed measures of past-year engagement in direct and indirect support seeking and excessive reassurance seeking (ERS), preference for negative feedback, and depression severity at a follow-up assessment in summer 2021. Greater attachment anxiety at baseline predicted more frequent direct support seeking, indirect support seeking, and ERS during the 1-year follow-up period. In turn, greater indirect support seeking predicted greater increases in depression from baseline to follow-up. Greater attachment avoidance at baseline predicted less direct support seeking during the 1-year follow-up period. Greater attachment avoidance at baseline also predicted depression severity at follow-up, particularly among mothers with moderate to high levels of attachment anxiety, although none of the examined support and feedback-seeking behaviours mediated this association. These results provide support for the role of activated attachment systems in determining support and feedback-seeking behaviour during stress, as well as the role of support and feedback-seeking behaviour in the maintenance and exacerbation of depression.

Altered EEG Patterns in Individuals with Disorganized Attachment: An EEG Microstates Study.

Over the past years, different studies provided preliminary evidence that Disorganized Attachment (DA) may have dysregulatory and disintegrative effects on both autonomic arousal regulation and brain connectivity. However, despite the clinical relevance of this construct, few studies have investigated the specific alterations underlying DA using electroencephalography (EEG). Thus, the main aim of the current study was to investigate EEG microstate parameters of DA in a non-clinical sample (N = 50) before (pre) and after (post) the administration of the Adult Attachment Interview (AAI). Two EEG eyes-closed Resting State (RS) recordings were performed before and after the AAI, which was used for classifying the participants [i.e., Disorganized/Unresolved (D/U) or Organized/Resolved (O/R) individuals] and to trigger the attachment system. Microstates parameters (i.e., Mean Duration, Time Coverage and Occurrence) were extracted from each recording using Cartool software. EEG microstates clustering analysis revealed 6 different maps (labeled A, B, C, D, E, F) in both groups (i.e., D/U and O/R individuals) and in both conditions (i.e., pre-AAI and post-AAI). In the pre-AAI condition, compared to O/R individuals, D/U participants showed a shorter Mean Duration and Time Coverage of Map F; in the post-AAI condition, a significant reduction in the Mean Duration of Map E was also observed in D/U individuals. Finally, in the "within" statistical analysis (i.e., pre-AAI vs. post-AAI), only the D/U group exhibited a significant increase in Time Coverage of Map F after the AAI. Since these maps are associated with brain networks involved in emotional information processing and mentalization (i.e., Salience Network and Default Mode Network), our result might reflect the deficit in the ability to mentalize caregiver's interaction as well as the increased sensitivity to attachment-related stimuli typically observed in individuals with a D/U state of mind.

Over-Denture Attachment Systems: Systematic Review with Meta-Analysis

Current scientific growths for implant over-denture attachments. We focused on the following topics: attachment systems, retention of various attachments, stress distribution with different attachments, the design and fabrication of attachments, digital techniques in over denture attachments, and the effects of attachments in two-implant health. We found that plastic resin is commonly used for ball and bar attachments, whereas nylon resin is commonly used in locator attachments. The locator system offers a valuable attachment option for implant-retained over denture. Attachment retention reduces while lateral force increases with implant inclination in over denture. The higher the retention of an over-denture attachment, the higher the transferred stresses. Additionally, clip loading produces more stress in implants and precision elements than bar-retained dentures.

Nonlinear dynamics analysis of the attachment system and design of variable stiffness connecting bracket based on the complete aero-engine system

During the operation of the aero-engine, the attachment and brackets are subjected to various complex internal and external loads, which can pose risks to the structural integrity of the engine. To address this issue, this paper introduces a variable stiffness bracket designed for vibration reduction in the attachment system. Firstly, a finite element model (FEM) of the aero-engine was established using the Lagrangian method, incorporating the dual rotor-bearing system and bracket-attachment system. Subsequently, the vibration response of the system was solved using the Runge-Kutta method. The sources and propagation paths of vibration within the system were identified. Lastly, leveraging the material properties of Shape Memory Alloy (SMA), a stiffness-adjustable bracket for the aircraft engine was proposed to achieve active vibration reduction in the system. The results demonstrate that the variable stiffness bracket effectively reduces the resonance amplitude and frequency in the attachment system, exhibiting excellent vibration reduction and isolation capabilities.

The moderating role of parenting stress when it comes to romantic attachment and sexual satisfaction

Sexual satisfaction is at the heart of a thriving romantic relationship and is intertwined with both partners romantic attachment orientations. Prior research has found that insecure romantic attachment orientations (anxiety and avoidance) are associated with lower sexual satisfaction in oneself and one’s partner. Stress is known to exacerbate insecure attachment tendencies, and couples with children are often exposed to parenting stress, which has been associated with lower sexual satisfaction. It is therefore possible that parenting stress moderates the association between the attachment and sexual systems, such that among those who are high in parenting stress, the negative link between attachment insecurity and sexual satisfaction is stronger. The objective of this study was to examine the link between romantic attachment and sexual satisfaction, and the impact of parenting stress on this association. One hundred three mixed-sex couples completed self-report questionnaires and were included in actor and partner analyses. Both parents’ attachment avoidance was associated with their own reduced sexual satisfaction. Fathers’ attachment avoidance was associated with mothers’ reduced sexual satisfaction. Additionally, fathers’ parenting stress moderated the association between their own romantic attachment avoidance and their partner’s sexual satisfaction. Contrary to prediction, as fathers’ parenting stress increased, the association between their higher attachment avoidance and mothers’ lower sexual satisfaction became weaker. Findings are discussed in light of research and theory on the role of attachment and parenting stress for sexual satisfaction in couples with children.
