Sexual activity (re-)engagement following spinal cord injury: Identifying behavior change targets for intervention development.

OBJECTIVES: This study used the behavior change wheel to identify the priority behavioral factors for a tailored intervention to support (re-)engagement in sexual activity following a spinal cord injury (SCI). RESEARCH METHOD/DESIGN: Forty-eight semistructured interviews were conducted with participants from three outpatient/carer/clinician populations in the United Kingdom: people living with SCI, their partners/spouses, and healthcare professionals working in SCI rehabilitation. To identify potential strategies to facilitate (re-)engagement in sexual activity, the behavior change wheel (BCW) and behavior change technique taxonomy Version 1 were applied to code behavior change techniques (BCTs) present in interview transcripts. RESULTS: Six intervention functions, three policy categories, and 21 BCTs were identified as primary targets for interventions to support sexual (re-)engagement post-SCI. Increasing physical-related skills and training would promote physical capability, while sex-related knowledge and the understanding of sex-related health consequences would elevate psychological capability. A supportive healthcare team, alongside peer support and targeted environmental resources about sexual activity/well-being facilitate physical and social opportunities for sex. Motivation to (re-)engage in sexual activity comprised goal-driven reflective motivation to enhance beliefs about capabilities, and automatic motivation via emotional support and reward-based reinforcement. CONCLUSIONS: This study outlines the key BCW and theoretically-derived intervention targets which now provide the foundation for innovative future interventions in SCI and sexual activity. Targeting these highly specific BCTs increases the likelihood that sexual satisfaction can become universally accessible after SCI. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Confirmatory structural validation and refinement of the Recurrent Urinary Tract Infection Symptom Scale.

Objectives: To confirm the structural validity of the Recurrent Urinary Tract Infection Symptom Scale (RUTISS), determining whether a bifactor model appropriately fits the questionnaire's structure and identifying areas for refinement. Used in conjunction with established clinical testing methods, this patient-reported outcome measure addresses the urgent need to validate the patient perspective. Patients and methods: A clinically and demographically diverse sample of 389 people experiencing recurrent UTI across 37 countries (96.9% female biological sex, aged 18-87 years) completed the RUTISS online. A bifactor graded response model was fitted to the data, identifying potential items for deletion if they indicated significant differential item functioning (DIF) based on sociodemographic characteristics, contributed to local item dependence or demonstrated poor fit or discrimination capability. Results: The final RUTISS comprised a 3-item symptom frequency section, a 1-item global rating of change scale and an 11-item general 'rUTI symptom and pain severity' subscale with four sub-factor domains measuring 'urinary symptoms', 'urinary presentation', 'UTI pain and discomfort' and 'bodily sensations'. The bifactor model fit indices were excellent (root mean square error of approximation [RMSEA] = 0.041, comparative fit index [CFI] = 0.995, standardised root mean square residual [SRMSR] = 0.047), and the mean-square fit statistics indicated that all items were productive for measurement (mean square fit indices [MNSQ] = 0.64 - 1.29). Eighty-one per cent of the common model variance was accounted for by the general factor and sub-factors collectively, and all factor loadings were greater than 0.30 and communalities greater than 0.60. Items indicated high discrimination capability (slope parameters > 1.35). Conclusion: The 15-item RUTISS is a patient-generated, psychometrically robust questionnaire that dynamically assesses the patient experience of recurrent UTI symptoms and pain. This brief tool offers the unique opportunity to enhance patient-centred care by supporting shared decision-making and patient monitoring.

Evaluating the quality of life impact of recurrent urinary tract infection: Validation and refinement of the Recurrent UTI Impact Questionnaire (RUTIIQ).

BACKGROUND AND AIMS: Recurrent urinary tract infection (rUTI) has significant negative consequences for a wide variety of quality of life (QoL) domains. Without adequate validation and assessment of the unique insights of people living with rUTI, clinical results cannot be fully understood. The Recurrent UTI Impact Questionnaire (RUTIIQ), a novel patient-reported outcome measure of rUTI psychosocial impact, has been robustly developed with extensive patient and clinician input to facilitate enhanced rUTI management and research. This study aimed to confirm the structural validity of the RUTIIQ, assessing its strength and bifactor model fit. METHODS: A sample of 389 adults experiencing rUTI (96.9% female, aged 18-87 years) completed an online cross-sectional survey comprising a demographic questionnaire and the RUTIIQ. A bifactor graded response model was fitted to the data, optimizing the questionnaire structure based on item fit, discrimination capability, local dependence, and differential item functioning. RESULTS: The final RUTIIQ demonstrated excellent bifactor model fit (RMSEA = 0.054, CFI = 0.99, SRMSR = 0.052), and mean-square fit indices indicated that all included items were productive for measurement (MNSQ = 0.52-1.41). The final questionnaire comprised an 18-item general "rUTI QoL impact" factor, and five subfactor domains measuring "personal wellbeing" (three items), "social wellbeing" (four items), "work and activity interference" (four items), "patient satisfaction" (four items), and "sexual wellbeing" (three items). Together, the general factor and five subfactors explained 81.6% of the common model variance. All factor loadings were greater than 0.30 and communalities greater than 0.60, indicating good model fit and structural validity. CONCLUSIONS: The 18-item RUTIIQ is a robust, patient-tested questionnaire with excellent psychometric properties, which capably assesses the patient experience of rUTI-related impact to QoL and healthcare satisfaction. Facilitating standardized patient monitoring and improved shared decision-making, the RUTIIQ delivers the unique opportunity to improve patient-centered care.

The Recurrent Urinary Tract Infection Symptom Scale: Development and validation of a patient-reported outcome measure.

Objectives: This study aimed to develop and validate a tailored patient-reported outcome measure (PROM) evaluating the patient experience of recurrent urinary tract infection (rUTI) symptom severity. This measure was designed to supplement clinical testing methods, allowing full assessment of the patient experience of rUTI symptom burden, while enhancing patient-centred UTI management and monitoring. Subjects and Methods: The Recurrent Urinary Tract Infection Symptom Scale (RUTISS) was developed and validated using a three-stage methodology, in accordance with gold-standard recommendations. Firstly, a two-round Delphi study was conducted to gain insights from 15 international expert clinicians working in rUTI, developing an initial pool of novel questionnaire items, assessing content validity and making item refinements. Next, two phases of one-to-one semi-structured cognitive interviews were conducted with a diverse sample of 28 people experiencing rUTI to assess questionnaire comprehensiveness and comprehensibility, making refinements after each phase. Finally, a comprehensive pilot of the RUTISS was conducted with 240 people experiencing rUTI across 24 countries, providing data for psychometric testing and item reduction. Results: Exploratory factor analysis indicated a four-factor structure comprising: 'urinary pain and discomfort', 'urinary urgency', 'bodily sensations' and 'urinary presentation', together accounting for 75.4% of the total variance in data. Qualitative feedback from expert clinicians and patients indicated strong content validity for items, which was supported by high content validity indices in the Delphi study (I-CVI > 0.75). Internal consistency and test-retest reliability of the RUTISS subscales were excellent (Cronbach's α = 0.87-0.94 and ICC = 0.73-0.82, respectively), and construct validity was strong (Spearman's ρ = 0.60-0.82). Conclusion: The RUTISS is a 28-item questionnaire with excellent reliability and validity, which dynamically assesses patient-reported rUTI symptoms and pain. This new PROM offers a unique opportunity to critically inform and strategically enhance the quality of rUTI management, patient-clinician interactions, and shared-decision making by monitoring key patient-reported outcomes.

Development and psychometric validation of a patient-reported outcome measure of recurrent urinary tract infection impact: the Recurrent UTI Impact Questionnaire.

PURPOSE: Recurrent urinary tract infection (rUTI) is a highly prevalent condition associated with significant poor quality of life outcomes. A patient-reported outcome measure (PROM) of rUTI-associated psychosocial impact is urgently required to supplement clinical evaluation and validate the challenges experienced by patients. This study therefore developed and validated the Recurrent UTI Impact Questionnaire (RUTIIQ). METHODS: A rigorous four-stage methodology was followed: (I) concept elicitation through a qualitative survey of the experiences of people with rUTI (N = 1983); (II) Delphi expert screening of the RUTIIQ with expert rUTI clinicians (N = 15); (III) one-to-one cognitive interviews with people experiencing rUTI (N = 28) to evaluate the comprehensiveness and comprehensibility of the RUTIIQ, and (IV) full pilot testing of the RUTIIQ with people experiencing rUTI (N = 240) to perform final item reduction and psychometric analysis. RESULTS: Exploratory factor analysis demonstrated a five-factor structure comprising: 'patient satisfaction', 'work and activity interference', 'social wellbeing', 'personal wellbeing', and 'sexual wellbeing', collectively accounting for 73.8% of the total variance in pilot scores. Results from expert clinicians and patients indicated strong item content validity (I-CVI > .75). The internal consistency and test-retest reliability of the RUTIIQ subscales were excellent (Cronbach's α = .81-.96, ICC = .66-.91), and construct validity was strong (Spearman's ρ > .69). CONCLUSION: The RUTIIQ is a 30-item questionnaire with excellent psychometric properties, assessing the patient-reported psychosocial impact of living with rUTI symptoms and pain. This new instrument delivers the unique opportunity to enhance patient-centred care through standardised observation and monitoring of rUTI patient outcomes. TRIAL REGISTRATION: This study was pre-registered with ClinicalTrials.gov (identifier: NCT05086900).

Lack of Awareness, Body Confidence and Connotations of Sex: An Interpretative Phenomenological Analysis of Barriers Affecting the Decision to Attend Initial Cervical Cancer Screening.

This study sought to understand how cervical cancer screening (CCS) awareness, sexual connotations and body image influenced the likelihood of CCS uptake in women yet to attend. Eleven females, aged 23-24, yet to attend CCS, were purposefully sampled. Interview transcripts were analysed using interpretative phenomenological analysis, generating three superordinate themes: (1) building screening expectations, (2) confronting sexual connotations and (3) growing pains. Findings demonstrated how a lack of awareness of CCS and the sexual connotations implicit in CCS acted as a barrier to attendance, exacerbated by negative body image comparisons between oneself and online or social media-based images. The perceived sexual connotations of CCS, and the resulting embarrassment, bolsters the case for self-screening, removing the need to attend clinic screening appointments. Reconceptualising screening using a theoretical model of the relationship between body image disturbances and body-focused screening behaviours among women, could lead to the development of pro-screening social media interventions.

"You feel a bit unsexy sometimes": The psychosocial impact of a spinal cord injury on sexual function and sexual satisfaction.

STUDY DESIGN: A qualitative, semi-structured interview design. OBJECTIVES: This study aimed to identify, from the perspective of people living with a Spinal Cord Injury (SCI), the primary psychosocial barriers and facilitators that impact on their sexual function and sexual satisfaction post-injury. SETTING: Community-dwelling sample of people with SCI in England, United Kingdom METHODS: Semi-structured interviews with twenty people with SCI (15 males; 5 females) were conducted using an 8-item interview schedule. Inductive thematic analysis was undertaken of verbatim transcripts coded using Braun and Clarke's (2021) six phases of thematic analysis. RESULTS: Six inductive themes were generated, collectively describing the psychosocial barriers and facilitators impacting on sexual function and satisfaction post-SCI: (1) Internalising societal views and stigmatisation; (2) Diminished sexual confidence; (3) Navigating communication; (4) Managing relationship dynamics; (5) Lack of sexual support provision; and (6) Intervention development recommendations. CONCLUSION: Sexual function and satisfaction are highly challenging areas of rehabilitation for males and females living with SCI. Increased efforts are needed to educate others in society to overcome the negative stereotypical attitudes obstructing acceptance of sex despite disability. Countering sexual stigmatisation for people with SCI would facilitate growth in sexual confidence. Techniques to enhance interpersonal sexual communication and involve the partner/spouse in regaining mutual sexual satisfaction are foundational. The current study highlighted key outpatient-based recommendations for intervention development, clarifying primary targets for future SCI-focused sexual therapeutic work.

Sexual function and sexual satisfaction following spinal cord injury: an interpretative phenomenological analysis of partner experiences.

PURPOSE: This study explored how partners/spouses of people with Spinal Cord Injury (SCI) experienced intimacy, sexual function, and sexual satisfaction post-SCI. MATERIALS AND METHODS: Qualitative, semi-structured interviews were conducted with the partners/spouses of people with SCI living in the community in the United Kingdom. Twelve participants (7 females; 5 males) were recruited using purposive sampling. A nine-item semi-structured interview design was used. Interviews were transcribed verbatim and analysed via Interpretative Phenomenological Analysis (IPA). RESULTS: Three superordinate themes were demonstrated: (1) Stolen sex through unpreparedness; (2) Redefining sex; and (3) Compromised commitment. Partners struggled to come to terms with the shock of radically altered post-SCI sexual relationships, questioning how their changed sexual relationship and sexual identity conflicted with caring requirements. To minimise post-SCI relationship changes, some partners engaged in strategies to protect against, distract from and avoid sexual intimacy, whereas others were able to retain adapted pre-injury patterns of intimate behaviour. CONCLUSION: Compromised sexual function and satisfaction significantly disrupt relationship dynamics post-SCI, initiate voluntary celibacy, and limit the perceived viability of continued sexual intimacy. Specialist partner-support provisions are urgently needed, recognising that partner support needs are not restricted to the inpatient rehabilitation phase but importantly extend long past discharge into the community.

Sexual function and satisfaction are highly challenging areas for partners post-spinal cord injury (SCI).Support and education for the partner must be incorporated into SCI rehabilitation to help with both adjustment and acceptance to changes in sexual functioning post-SCI.Partner contributions to and experiences of sexual function and satisfaction should be given more value, as these aid in the sustainability of healthy sexual relationships and psychological wellbeing following SCI.

Supporting Sexual Functioning and Satisfaction During Rehabilitation after Spinal Cord Injury: Barriers and Facilitators Identified by Healthcare Professionals.

OBJECTIVE: To explore healthcare professionals' perspectives on the barriers and facilitators impacting provision of support for sexual functioning/satisfaction during spinal cord injury rehabilitation. DESIGN: Qualitative, semi-structured interview design. METHODS: Sixteen healthcare professionals working in spinal cord injury rehabilitation settings were recruited (14 females, 2 males). Semi-structured interviews were conducted using a 9-item interview guide. Interviews were transcribed verbatim and inductively analysed following Braun and Clarke's (2006) 6 phases of thematic analysis. RESULTS: Five inductive themes were generated describing healthcare professional-perceived barriers and facilitators impacting upon care delivery postspinal cord injury: (1) Integrating sexual wellbeing in rehabilitation; (2) Sex-informed multi-disciplinary teams; (3) Acknowledging awkwardness; (4) Enhancing approachability; and (5) Recognizing the partner. CONCLUSION: Sexual functioning and satisfaction are priority areas for rehabilitation, yet they are persistently side-lined in multi-disciplinary team (MDT) rehabilitation agendas. Healthcare professionals do not feel supported to engage with their patients to improve and manage sexual functioning/satisfaction. Ensuring that healthcare professionals are equipped and made aware of sexuality-specific guidelines and operational frameworks, which can be easily interpreted, structured and implemented as a standard part of spinal cord injury rehabilitation is key. This would be instrumental in enabling healthcare professionals to be more informed and comfortable in creating an atmosphere in which sexual topics can be openly discussed to support individuals with spinal cord injury.

Adaptations to mindfulness-based interventions for neurological impairment: The SMALL PROMPTS approach.

PURPOSE/OBJECTIVE: Standardized mindfulness-based interventions (MBIs), used for the management of physical and psychological symptoms associated with neurological impairment/injury (NI), have been problematized as lacking accessibility due to their focus on sensory presence and mindful walking. Research is needed to generate formalized recommendations regarding how MBIs may be best adapted to enhance their suitability for people with NI. RESEARCH METHOD/DESIGN: A two-phase qualitative study was completed. First, semistructured interviews were undertaken with eight accredited mindfulness teachers with NI. Interviews reviewed the adaptations participants made in their personal and teaching practice, using thematic analysis, and generated recommendations for adaptations to MBIs specific to people with NI. Second, using the DELPHI method, the adapted practice recommendations were reviewed and revised via three rounds, following cognitive interviews with an expert panel (N = 5 trained mindfulness teachers with NI). RESULTS: Ten core areas for adaptation are proposed and validated, acting as SMALL PROMPTS which can be used to adapt mindfulness-based teaching techniques to the specific requirements of people with NI: (a) Skin/bladder/bowel management; (b) mindful Movement; (c) Accessible training; (d) Language Leadership; (e) Permissive pRactice; (f) Optimizing timelines; (g) Management of posture; (h) inclusion of Pacing; (i) Teaching from experience; and (j) body Scanning. CONCLUSION/IMPLICATIONS: Mindfulness is a highly applicable approach for people with sensory loss, however significant, specific adaptations are required to improve inclusivity and accessibility. The SMALL PROMPTS adaptations increase the accessibility, applicability, and utility of MBIs for populations living with NI, enhancing effective management of physical and psychological wellbeing, and optimizing MBI delivery.

The Influence of Adverse Childhood Experiences in Pain Management: Mechanisms, Processes, and Trauma-Informed Care.

Adverse childhood experiences (ACEs) increase the likelihood of reduced physical and psychological health in adulthood. Though understanding and psychological management of traumatic experiences is growing, the empirical exploration of ACEs and physical clinical outcomes remains under-represented and under-explored. This topical review aimed to highlight the role of ACEs in the experience of chronic pain, pain management services and clinical decision making by: (1) providing an overview of the relationship between ACEs and chronic pain; (2) identifying biopsychosocial mechanisms through which ACEs may increase risk of persistent pain; (3) highlighting the impact of ACEs on patient adherence and completion of pain management treatment; and (4) providing practical clinical implications for pain management. Review findings demonstrated that in chronic pain, ACEs are associated with increased pain complications, pain catastrophizing and depression and the combination of these factors further heightens the risk of early treatment attrition. The pervasive detrimental impacts of the COVID-19 pandemic on ACEs and their cyclical effects on pain are discussed in the context of psychological decline during long treatment waitlists. The review highlights how people with pain can be further supported in pain services by maintaining trauma-informed practices and acknowledging the impact of ACEs on chronic pain and detrimental health outcomes. Clinicians who are ACE-informed have the potential to minimize the negative influence of ACEs on treatment outcomes, ultimately optimizing the impact of pain management services.

Using the COM-B model to characterize the barriers and facilitators of pre-exposure prophylaxis (PrEP) uptake in men who have sex with men.

OBJECTIVES: Using the COM-B model, this study aimed to characterize barriers and facilitators to pre-exposure prophylaxis (PrEP) uptake amongst men who have sex with men (MSM). DESIGN AND METHOD: Semistructured interviews with 13 MSM who were non-PrEP users were conducted with a specific focus on barriers and facilitators to PrEP uptake. A 15-item interview schedule was created informed by the COM-B model. Transcripts were transcribed verbatim and inductively analysed using thematic analysis. To illustrate pathways for intervention design, inductive themes were then deductively mapped onto COM-B constructs. RESULTS: Results demonstrated that barriers to PrEP uptake were closely aligned with five (of six) COM-B components: psychological capability, physical opportunity, social opportunity, reflective motivation and automatic motivation. These COM-B subcomponents reflected seven thematized barriers: (1) limited information about PrEP, (2) restricted access to PrEP, (3) gay identity and sexual stigmatization, (4) social and cultural stigmatization, (5) capabilities in treatment adherence, (6) optimistic bias about sexual behaviours and (7) calculating risk. No facilitators or physical capability concerns were demonstrated. CONCLUSION: This study adopted a novel behaviour change-informed approach to understanding barriers and facilitators to PrEP uptake amongst MSM. Unrealistic optimism about self-protective individual behaviours, the physical accessibility of PrEP and (mis)information together interacted closely with perceptions of personal and social stigmatization to dynamically impact PrEP uptake decisions. Barriers to PrEP uptake mapped clearly to the COM-B; therefore, these results provide the foundation for Behaviour Change Wheel intervention development to improve rates of PrEP uptake and its acceptability for MSM.

Patient-to-Patient Interactions During the Pain Management Programme: The Role of Humor and Venting in Building a Socially Supportive Community.

Objectives: Social support is most positively perceived when there is an optimal match between a patient's need for communication and the purpose of their interaction. Maladaptive communication patterns may inhibit social bonding or mutual support, negatively impacting clinical outcomes. This study aimed to identify how people with chronic pain naturalistically converse together about their pain in the context of a Pain Management Programme (PMP). Methods: Seven participants (4 females; 3 males) with ongoing chronic pain who were attending a PMP in a regional hospital in the United Kingdom were audio/video recorded during breaks in their PMP. Interactions were transcribed using Jeffersonian Transcription and analyzed using Conversation Analysis. Results: Two conversational mechanisms were identified: (1) Conversational humor; and (2) A venting cycle. Participants used their pain-related experiences construct a motive for a joke, then proceeded to deliver the joke, which initiated a joke return from observers. The sequence was completed by a collaborative punchline. In the venting cycle, an initial complaint was escalated by the sharing of comparable experiences, after which the vent was concluded through a joke punchline, acting as a pivot to move the conversation forwards, terminating the venting. Conclusions: Humorous interpersonal interactions about chronic pain provided a forum for social support-building within the PMP. Humor was affiliative and built social collaboration, helping individuals to together make sense of their pain in a prosocial atmosphere, approaching pain-related experiences with levity. Patient-to-patient interactions within the PMP were strongly prosocial and inclusive, potentially facilitating enhanced PMP clinical outcomes through collaboration.

Developing successful social support: An interpretative phenomenological analysis of mechanisms and processes in a chronic pain support group.

OBJECTIVE: The experience of long-term membership of a successful chronic pain support group (CPSG) was explored to identify; (i) factors associated with social support, and; (ii) ways that health care professionals (HCPs) could help CPSGs become more effective and supportive. DESIGN: Interpretative Phenomenological Analysis enabled exploration of participants' experiences of membership and rationales for continued attendance. MAIN OUTCOME MEASURES: Twelve participants (four males, eight females), recruited from a regional CPSG, completed semi-structured interviews lasting from 45 to 120 minutes. Following verbatim transcription, idiographic then cross-case analyses were undertaken. RESULTS: Three superordinate themes emerged: (1) Investing in the new normal; (2) The nurturing environment; (3) Growth facilitation through social evolution. Increased investment and identification with membership, generated snowballing social engagement, enhancing pain management/well-being through collective humour and peer-to-peer support. Explicit guidance by HCPs in early stages of group formation/development, and subsequent implicit influences on group attitudes and actions, promoted the group's development into its current healthy, supportive state. CONCLUSION: Contrary to stereotypes, membership offered positive respite from chronic pain through collective coping. Successful CPSGs forge an independent identity, fostering strong group investment and an ability to live well with chronic pain. HCPs can provide a stabilising foundation for CPSGs to develop positively and supportively.

Reflecting the transition from pain management services to chronic pain support group attendance: An interpretative phenomenological analysis.

OBJECTIVES: Transitioning from clinical care to community-based self-management represents a significant challenge, throughout which social support can facilitate health adjustment and quality of life. However, community-centred, peer-led support structures are often underused. This study aimed to investigate the decision-making processes involved in the choice to attend a chronic pain support group (CPSG) following discharge from a Pain Management Programme. DESIGN: An in-depth, qualitative analysis was undertaken using interpretative phenomenological analysis, exploring participants' subjective experiences, decision-making, and rationale for initial CPSG attendance. METHODS: Twelve participants (four males, eight females) were recruited from a regional CPSG and completed semi-structured interviews lasting between 45 and 120 min. Interviews were transcribed verbatim and analysed idiographically before a cross-case analysis was completed. RESULTS: Analysis of transcripts resulted in three superordinate themes: (1) The thirst for comparative friendship; (2) conjecture and the imminent choice; (3) progressive pain management. These themes reflect a desire for empathic, socially comparative friendships and the search for a forum in which to enhance pain self-management strategies, yet also internal conflict over initial CPSG attendance. CONCLUSION: Social support and associated friendships are attractive to prospective CPSG members and are conceptualized as opportunities to engage in social comparison and nurture self-care. The first visit to the support group presents a significant hurdle, but can be facilitated by managing the transition between therapeutic care and CPSG attendance. Clinicians can challenge preconceptions, foster positive viewpoints regarding the group and support collective decision-making to attend. Following initial attendance, psychosocial well-being was enhanced. Statement of contribution What is already known on this subject? Social support functions as a protective buffer against declining health. Joining a peer-led support group can be initially intimidating and the first visit presents a significant hurdle. What does this study add? Participants are predominantly attracted to support groups due to the opportunity to develop new friendships. Health-related peer groups function as fora for social comparison, enhancing self-esteem and self-efficacy. Experience of pain management programmes primes willingness to attend support groups. The initial decision to attend is difficult but facilitated by collective, group decision-making processes. Health care professionals dynamically prime the transition towards peer support structures.

Effects of Fiber Reinforcement on Clay Aerogel Composites.

Novel, low density structures which combine biologically-based fibers with clay aerogels are produced in an environmentally benign manner using water as solvent, and no additional processing chemicals. Three different reinforcing fibers, silk, soy silk, and hemp, are evaluated in combination with poly(vinyl alcohol) matrix polymer combined with montmorillonite clay. The mechanical properties of the aerogels are demonstrated to increase with reinforcing fiber length, in each case limited by a critical fiber length, beyond which mechanical properties decline due to maldistribution of filler, and disruption of the aerogel structure. Rather than the classical model for reinforced composite properties, the chemical compatibility of reinforcing fibers with the polymer/clay matrix dominated mechanical performance, along with the tendencies of the fibers to kink under compression.
