Background: Chronic pain affects up to 20% of the population and often results in significant distress, disability, and reduced quality of life. Despite compelling evidence for behavioural treatments, treatment access remains limited. To improve access, a digital behavioural treatment for chronic pain was developed as part of the multi-phase 'DAHLIA' project. The present study evaluates the effects of this newly developed digital behavioural treatment.

Methods: Data were collected in a single-arm, iterative trial using a replicated single-case experimental design (SCED). In total, 56 participants received treatment (mean age 47, 87% female, varied pain regions). Participants completed twice daily digital diaries and questionnaires at pre-, and post-treatment, and at 3- and 6-months follow-ups. Diary items and questionnaires assessed psychological flexibility and acceptance, pain-related functioning, pain intensity, and general well-being. Daily diary data were examined using a combined p-value approach to conduct a meta-analysis of the SCED data, and questionnaire data were analysed using linear mixed models.

Results: Meta-analyses of daily diary data showed significant improvements in most pain-related items, indicating the utility of treatment in everyday life. Linear mixed model analyses of effects showed significant improvements over time in key outcomes with the largest changes observed in pain acceptance and psychological flexibility and smaller effects in pain-related functioning.

Conclusion: This study provides initial evidence for the newly developed digital behavioural treatment for chronic pain. Findings suggest that the treatment can improve resilience, daily functioning and symptoms and suggest the potential of the treatment as an effective evidence-based treatment for chronic pain.

BACKGROUND: Chronic pain affects 20%-30% of the population worldwide, leading to significant distress, disability and financial burden. Pain management strategies focusing on pain reduction have shown limited effects on functioning; however, behavioural treatments aimed at enhancing resilience have demonstrated strong empirical support. Digital solutions offer new opportunities for delivering evidence-based treatments, but evaluation at the individual level is needed. The aim of this study is to examine individual-level treatment effects of a digital behavioural treatment for chronic pain in a heterogeneous sample.

METHODS: A study with a single-case experimental design (SCED) was conducted with participants (N = 11) experiencing chronic pain (> 3 months) recruited through healthcare. Participants were randomised at baseline (5-10-day A-phase) and completed a 6-module digital treatment based on learning theory and well-established theories applied to chronic pain (6-8-week B-phase), with weekly therapist contact. Digital diaries, prompted twice daily, tracked psychological flexibility and acceptance, pain-related functioning, pain intensity and well-being. Data were analysed using visual analysis and effect size calculations.

RESULTS: N = 11 enrolled and data from n = 10 were analysed (n = 1 refused digital diary, n = 2 partial completers, n = 8 full completers). Pain profiles varied (e.g., chronic migraine, fibromyalgia, lower back pain, etc.). Several participants benefited from the treatment, though results varied across individuals and across outcomes.

CONCLUSION: The digital behavioural treatment showed promise in addressing diverse pain profiles and associated functioning. The variability in responses highlights the benefit of using SCED to explore individual-level effects, thus offering a methodological proof-of-concept. Findings support further development, including tailoring to match individual needs.

SIGNIFICANCE STATEMENT: This proof-of-concept study provides support for the utility of digital behavioural interventions and individual-level evaluation of treatment effects, highlighting the potential of personalised pain treatments. The findings contribute to the growing body of support for digital solutions as effective and accessible approaches to improve functioning and resilience for people with diverse pain experiences.

INTRODUCTION: Provoked vestibulodynia (PVD) is a prevalent persistent pain disorder, localized to the vulva, not only affecting the sexual health of women suffering from it but also of their partners. Partner's behavioral response to the pain has implications for the affected woman's pain and sexual function, as well as the relational dynamics of the couple.

OBJECTIVES: The main aim of this study was to explore facilitative, solicitous, and negative male partner responses to women with PVD and their links to demographic and psychosexual characteristics. Further, we investigated the discrepancies in psychosexual health between currently sexually active and inactive participants, as well as levels of anxiety and depressive symptoms within our sample of male partners (N = 127).

Methods: Cross-sectional associations were examined using bivariate correlations. Differences in psychosexual health between the two sub-samples were examined using Mann-Whitney U test.

RESULTS: Our results showed that facilitative partner responses were significantly associated with higher relationship and sexual satisfaction, as well as with lower sexual distress and more approach goals. Negative partner responses were significantly associated with higher sexual distress, as well as with lower relationship and sexual satisfaction. Negative partner responses were the only responses significantly associated with the men's anxiety and depression, which suggests that mental health plays a role in partners' management of vulvodynia. In our sample, 10.2% scored above cut-off for clinical levels of depressive symptoms and 8.7% for anxiety, similar to a Swedish community sample.

Conclusion: Partner responses were associated with psychosexual health. In our sample, male partners of women with PVD did not have more anxiety or depression than other men of the same age in the general population.

BACKGROUND: Recent research shows that chronic pain affects 27% of the adult population. For many, pain significantly impairs quality of life and everyday functioning. Behavioral interventions have shown utility, but access remains limited. Digital health solutions can increase reach, but there is a need for user-friendly, feasible, and evidence-based digital interventions.

OBJECTIVE: This study aimed to clarify how a digital behavioral intervention for people with chronic pain can be developed through a user-centered approach to address the needs and preferences of the target population.

METHODS: This study used a multimethod approach involving end users, namely, patients with chronic pain and therapists, to develop prototypes for a digital behavioral intervention across 3 phases. In the preparation phase (phase 0), fictional patient personas (n=3) were created to represent the diversity of the target population while emphasizing transdiagnostic features across people with chronic pain. In the design phase (phase 1), qualitative data from focus groups with patients (n=5; aged 37-51 years; 4/5, 80% women; 2/5, 40% diagnosed with Ehlers-Danlos syndrome; 3/5, 60% either undiagnosed or uncertain about their diagnosis) and therapists (n=12 licensed psychologists; aged 29-64 years; 9/12, 75% women) were collected to explore end-user preferences for the intervention design and content. In the testing phase (phase 2), the initial full prototype of the digital intervention was piloted with patients (n=11; aged 36-58 years; 9/11, 82% women; with diverse diagnoses, including migraine, arthritis, fibromyalgia, complex regional pain syndrome, hypermobile Ehlers-Danlos syndrome, herniated disc, chronic fatigue syndrome, and 1/11, 9% cases of undiagnosed pain) and therapists (n=3 licensed psychologists; aged 36-58 y; 3/3, 100% women). The Consolidated Framework for Implementation Research was used to structure analyses of end-user feedback.

RESULTS: On the basis of end-user input, a 6-week digital behavioral intervention for chronic pain was created. Focus groups highlighted the importance of accessibility and adaptability of the digital intervention, emphasizing the need for tailored content, flexibility (eg, contact with the therapist via asynchronous messaging, telephone, or video calls), and user-friendly design (eg, easy navigation between modules, short microsessions, and visualizations). Average weekly ratings (scale from 1=not at all to 7=very much) by patients during pilot-testing indicated that the intervention was helpful (mean range 4.27-5.45, SD range 1.20-2.20), enjoyable (mean range 3.81-4.81, SD range 1.12-2.08), and understandable (mean range 4.45-6, SD range 1.30-1.86), suggesting initial acceptability and usability of the intervention.

CONCLUSIONS: The results illustrated the utility of the patient personas when preparing, of the focus groups when designing, and of the end-user feedback when testing this new digital intervention for people with chronic pain. The findings indicated that the intervention is promising while also providing relevant end-user suggestions (eg, video content, text-to-speech function, and add-on modules) to guide further improvements.

A considerable number of pregnant women experience fear of childbirth (FOC), characterized by worries and fear of the unpredictable. Despite this, the psychological processes in FOC have received notably little attention. The aim of this study was to advance the understanding by exploring the applicability of the Intolerance of Uncertainty (IU) model on FOC. Anonymous data was collected in a sample of pregnant women (N = 357) with varying levels of FOC. Analyses supported the associations between FOC and all proposed psychological processes: IU, negative problem orientation, positive beliefs about worry and avoidance of inner experiences. The exploration of potential mediators of the relation between IU and FOC revealed that, of the three processes from the model, only positive beliefs about worry were a mediator, and more specifically, a partial mediator between IU and FOC. These findings add to the theoretical understanding of FOC, by indicating that the role of IU may be similar to other conditions inflicted by worry and anxiety, which may inform treatment development.

Endometriosis, a chronic gynecological disease affecting approximately 10% of women of reproductive age, has a significant impact on physical and mental health. This cross-sectional study aimed to explore experiences of validating and invalidating communication in three contexts (with healthcare providers, employers, and family/friends), and whether this may predict health-related quality of life (HRQoL) in women with endometriosis. Data was collected through a digital survey distributed to women with self-reported endometriosis in Sweden. The survey included measures of validating and invalidating communication, depressive symptoms, anxiety, and HRQoL. A total of 427 women participated. The results indicated that women experienced varying levels of validating and invalidating communication in different contexts, with close family/friends providing the highest level of validation, and healthcare providers the lowest. Furthermore, a combined construct of high levels of validation and low levels of invalidation from healthcare providers and from close family and friends were significant predictors of HRQoL. These findings highlight the importance of supportive communication and understanding from healthcare providers and close social networks in promoting the well-being of women with endometriosis. Future research should further explore the impact of validating communication within healthcare settings and develop interventions to improve communication and support for women with endometriosis.

Vulvodynia is common and has an immense impact on affected women and their partners. Psychological factors have been found to contribute to pain maintenance and exacerbation, and treatments addressing psychological factors have yielded positive results. This study employed a replicated single-case experimental design to examine a cognitive behavioral therapy (CBT) group treatment with partner involvement in vulvodynia. Repeated measures of pain intensity related to pain-inflicting behaviors were collected weekly throughout baseline and treatment phases. Associated outcomes were measured pre-, post- and at two follow-up assessments. Participants were 18-45-year-old women, in a stable sexual relationship with a man, experiencing vulvodynia. Five women completed the treatment consisting of 10 group sessions and 3 couple sessions. Data were analyzed through visual inspection and supplementary nonparametric calculations. The study showed promising results of the CBT treatment in alleviating pain intensity in connection to specific pain-inflicting behavior since three out of five participants showed improvements. For the participants who improved, sexual function, pain catastrophizing, avoidance, and endurance behavior changed during treatment and were maintained at follow-ups. These results warrant further study of the CBT treatment, in larger, and controlled formats.

Over the last decades, psychological mechanisms have been identified as key in the understanding of pain development and maintenance of vulvodynia. Furthermore, psychological treatments in the form of cognitive behavioral therapy (CBT) have proven helpful for those suffering. Still, prospective studies investigating psychological mechanisms over time are lacking, as are clinical studies investigating their role in treatment.

The overall aim of this dissertation is to further the understanding of pain-related behavior and its role in the development and maintenance of vulvodynia by applying a fear-avoidance-endurance theoretical framework. It further aimed at consolidating the understanding of such a framework through a clinical proof of concept investigating the effect of a CBT treatment. Study I investigated the mediating role of avoidance and endurance behavior on the relationship between pain catastrophizing and pain. Study II prospectively investigated the predictive value of avoidance and endurance behavior on sexual function. Further, avoidance and endurance behavior were examined on an individual level to gain information on potential patterns of behavior. Study III investigated the effect of a CBT group treatment with partner involvement on pain and associated outcomes.

Taken together, the overall findings of this dissertation further point at the importance of psychological mechanisms such as pain catastrophizing, avoidance behavior, and endurance behavior in the development and maintenance of vulvodynia. While further manifesting similarities between mechanisms involved in vulvodynia and those involved in other persistent pain conditions, the findings also verify the relevance of the Fear-avoidance model and the complementary Avoidance-endurance model for vulvodynia. Finally, a new model of understanding was proposed: the Fear-avoidance-endurance model of vulvodynia, summarizing pain-related behavior involved in the development and maintenance of vulvodynia.

OBJECTIVE: Persistent vulvovaginal pain affects many women and often has adverse effects on sexual functioning. Psychological inflexibility related to pain is associated with distress and functional disability across different types of chronic pain conditions, but little is known about the role of psychological inflexibility in vulvovaginal pain. The present study examines psychological inflexibility related to pain as a predictor of sexual functioning over time among women with vulvovaginal pain.

METHODS: Questionnaires including measures of psychological inflexibility, pain severity, and sexual functioning were administered to female university students at two points in time. One hundred thirty women with vulvovaginal pain responded to the questionnaire at baseline and at follow-up after 10 months. A multiple regression model was used to explore psychological inflexibility and pain severity as predictors of sexual functioning at follow-up.

RESULTS: Higher levels of psychological inflexibility and more severe pain at baseline were associated with poorer sexual functioning 10 months later. In analysis adjusting for baseline levels of sexual functioning, psychological inflexibility was the only significant predictor of sexual functioning at follow-up.

CONCLUSIONS: The findings provide preliminary evidence that psychological inflexibility is associated with sexual adjustment over time among women with vulvovaginal pain and point to the relevance of further examinations of the psychological inflexibility model in the context of vulvovaginal pain.

Background: Recurring vulvovaginal pain is common, with evident effects on affected women's lives. Little is known about how affected women cope with painful sexual activities and how coping relates to pain intensity and psychosexual functioning over time. This prospective study explored the impact of avoidance and endurance on sexual function over time. Additionally, patterns of coping were studied on an individual level to increase knowledge about coping and its relation to psychosexual functioning.

Methods: One hundred and seventeen women, 18-35years old, with recurring vulvovaginal pain answered questionnaires at two measurement points, five months apart, assessing avoidance and endurance coping, pain intensity and psychosexual functioning. A multiple regression model explored the predictive value of avoidance and endurance on sexual function over time. Cluster analyses investigated patterns of coping and stability within the clusters. These subgroups were compared on psychosexual outcomes.

Results: Avoidance at baseline was the only significant predictor of sexual function five months later. Distinct and stable subgroups with different patterns of coping were identified, where avoidance and endurance coping were used both separately and combined. Women who both avoided and endured had the most unfavourable outcomes in terms of psychosexual functioning.

Conclusions: Avoidance of sexual activities was related to reduced sexual function over time, which calls for attention and clinical interventions targeting avoidance. Additionally, women who both avoid and endure sexual activities despite pain possibly need tailored interventions, as women with this coping pattern reported the lowest levels of psychosexual functioning.

Significance: In this prospective study, avoidance of sexual activities predicted sexual function over time, when controlling for pain intensity. Subgroups of women using distinct patterns of coping were identified. Those who both avoided and endured had the lowest levels of psychosexual functioning.
