Positive Psychological Wellbeing Is Required for Online Self-Help Acceptance and Commitment Therapy for Chronic Pain to be Effective

The web-based delivery of psychosocial interventions is a promising treatment modality for people suffering from chronic pain, and other forms of physical and mental illness. Despite the promising findings of first studies, patients may vary in the benefits they draw from self-managing a full-blown web-based psychosocial treatment. We lack knowledge on moderators and predictors of change during web-based interventions that explain for whom web-based interventions are especially (in)effective. In this study, we primarily explored for which chronic pain patients web-based Acceptance and Commitment Therapy (ACT) was (in)effective during a large three-armed randomized controlled trial. Besides standard demographic, physical and psychosocial factors we focused on positive mental health. Data from 238 heterogeneously diagnosed chronic pain sufferers from the general Dutch population following either web-based ACT (n = 82), or one of two control conditions [web-based Expressive Writing (EW; n = 79) and Waiting List (WL; n = 77)] were analysed. ACT and EW both consisted of nine modules and lasted nine to 12 weeks. Exploratory linear regression analyses were performed using the PROCESS macro in SPSS. Pain interference at 3-month follow-up was predicted from baseline moderator (characteristics that influence the outcome of specific treatments in comparison to other treatments) and predictor (characteristics that influence outcome regardless of treatment) variables. The results showed that none of the demographic or physical characteristics moderated ACT treatment changes compared to both control conditions. The only significant moderator of change compared to both EW and WL was baseline psychological wellbeing, and pain intensity was a moderator of change compared to EW. Furthermore, higher pain interference, depression and anxiety, and also lower levels of emotional well-being predicted higher pain interference in daily life 6 months later. These results suggest that web-based self-help ACT may not be allocated to chronic pain sufferers experiencing low levels of mental resilience resources such as self-acceptance, goals in life, and environmental mastery. Other subgroups are identified that potentially need specific tailoring of (web-based) ACT. Emotional and psychological wellbeing should receive much more attention in subsequent studies on chronic pain and illness

Exploring facilitators and barriers to using a person centered care intervention in a nursing home setting

Person-centered care (PCC) interventions have the potential to improve resident well-being in nursing homes, but can be difficult to implement. This study investigates perceived facilitators and barriers reported by nursing staff to using a PCC intervention consisting of three components: assessment of resident well-being, planning of well-being support, and behavioral changes in care to support resident well-being. Our explorative mixed method study combined interviews (n = 11) with a longitudinal survey (n = 132) to examine which determinants were most prevalent and predictive for intention to use the intervention and actual implementation 3 months later (n = 63). Results showed that perceived barriers and facilitators were dependent on the components of the intervention. Assessment of resident well-being required a stable nursing home context and a detailed implementation plan, while planning of well-being support was impeded by knowledge. Behavioral changes in nursing care required easy integration in daily caring tasks and social support

Beyond adaptive mental functioning with pain as the absence of psychopathology: Prevalence and correlates of flourishing in two chronic pain samples

Chronic pain outcomes are traditionally defined in terms of disability and illness. A definition of adaptive functioning in the context of chronic pain beyond the mere absence of negative outcomes, is the ability to flourish (i.e., experience emotional, psychological and social well-being; Keyes, 2002). We explored in two chronic pain samples the prevalence and sociodemographic, physical and psychological correlates of flourishing, and complemented this exploration with a similar examination of (being at risk for) psychopathology to help contextualize findings. Sample 1 (n = 1498) was a nationally representative sample. Subgroups included people with regular joint pain (1), regular joint pain and rheumatoid arthritis (2) and without chronic pain (3). Using chi-square tests we calculated the prevalence of both mental health outcomes and examined if people with or without chronic pain were more/less likely to flourish/at risk for psychopathology. Sample 2 (n = 238) concerned baseline data of a Randomized Controlled Trial on the effectiveness of Acceptance and Commitment Therapy for chronic pain (Trompetter et al., 2015b). We performed logistic regression analysis to identify flourishers/those at risk for depression. The Mental Health Continuum-Short Form was used to measure flourishing. The prevalence of flourishing was 34% (recurrent joint pain) and 38% (recurrent joint pain and arthritis) in sample 1, and 23% in sample 2. Compared to those without chronic pain, people with chronic pain were as likely to flourish, but more likely to be at risk for psychopathology. In sample 2, both flourishing and being at risk for depression were related foremost to psychological correlates. While engaged living was the most important correlate of flourishing, pain catastrophizing and psychological inflexibility were most important correlates of being at risk for depression. In conclusion, people with chronic pain are able to flourish. Findings suggest that positive and negative chronic pain outcomes function on two different continua, with potentially unique protective and risk factors. The Psychological Flexibility model provides pathways to explain both poor and optimal functioning in the presence of chronic pain. A better understanding of people with chronic pain who are able to flourish can be a fruitful endeavor to improve chronic pain models and interventions

Acceptatie van pijn: problemen met de factoriële validiteit van de Nederlandse vertaling van de Chronic Pain Acceptance Questionnaire (CPAQ)

Acceptance of pain appears as an important factor in pain research and in\ud practice. Different measurement instruments were developed, among\ud which the Chronic Pain Acceptance Questionnaire (CPAQ;McCracken,\ud Vowles & Eccleston, 2004). In this study possible psychometric problems\ud with the Dutch version of the CPAQ are investigated. Different models of\ud the CPAQ, among which the general two-factor model (subscales Activity\ud Engagement and PainWillingness), were tested in confirmatory factor\ud analysis (N = 584). None of the models met the established fit criteria for\ud adequate fit. It is concluded that the factor structure of the Dutch version of\ud the CPAQ can not be confirmed; the scale as such should be rejected as a\ud useful measurement instrument. Alternative questionnaires to measure\ud acceptance of pain (ICQ, PaSol, PIPS) are suggeste

How and for whom does web-based acceptance and commitment therapy work? Mediation and moderation analyses of web-based ACT for depressive symptoms

Background: Acceptance and Commitment Therapy (ACT) has been demonstrated to be effective in reducing depressive symptoms. However, little is known how and for whom therapeutic change occurs, specifically in web-based interventions. This study focuses on the mediators, moderators and predictors of change during a web-based ACT intervention. Methods: Data from 236 adults from the general population with mild to moderate depressive symptoms, randomized to either web-based ACT (n = 82) or one of two control conditions (web-based Expressive Writing (EW; n = 67) and a waiting list (n = 87)), were analysed. Single and multiple mediation analyses, and exploratory linear regression analyses were performed using PROCESS and linear regression analyses, to examine mediators, moderators and predictors on pre- to post- and follow-up treatment change of depressive symptoms. Results: The treatment effect of ACT versus the waiting list was mediated by psychological flexibility and two mindfulness facets. The treatment effect of ACT versus EW was not significantly mediated. The moderator analyses demonstrated that the effects of web-based ACT did not vary according to baseline patient characteristics when compared to both control groups. However, higher baseline depressive symptoms and positive mental health and lower baseline anxiety were identified as predictors of outcome across all conditions. Similar results are found for follow-up. Conclusions: The findings of this study corroborate the evidence that psychological flexibility and mindfulness are distinct process mechanisms that mediate the effects of web-based ACT intervention. The results indicate that there are no restrictions to the allocation of web-based ACT intervention and that web-based ACT can work for different subpopulations

Psychological flexibility and catastrophizing as associated change mechanisms during online Acceptance & Commitment Therapy for chronic pain

The underlying mechanisms of the effectiveness of cognitive behavioural interventions for chronic pain need further clarification. The role of, and associations between, pain-related psychological flexibility (PF) and pain catastrophizing (PC) were examined during a randomized controlled trial on internet-based Acceptance & Commitment Therapy (ACT) for chronic pain. We assessed (1) the unique and combined indirect effects of PF and PC on outcomes, and (2) the causality of relations between PF, PC and the primary outcome pain interference in daily life (MPI) during ACT. A total of 238 pain sufferers were allocated to either ACT, a control condition on Expressive Writing, or a waiting list condition. Non-parametric cross-product of coefficients mediational analyses and cross-lagged panel designs were applied. Compared to control conditions, both baseline to post-intervention changes in PF and PC seemed to uniquely mediate baseline to three-month follow-up changes in pain interference and psychological distress. Only PF mediated changes in pain intensity. Indirect effects were twice as large for PF (κ² = .09–.19) than for PC (κ² PCS = .05–.10). Further assessment of changes during ACT showed, however, that only PF, and not PC, predicted subsequent changes in MPI, while early and late changes in both PF and PC predicted later changes in each other. In conclusion, only PF functioned as a direct, causal working mechanism during ACT, with larger indirect effects that occurred earlier than changes in PC. Additionally, PC may function as an indirect mechanism of change during ACT for chronic pain via its direct influence on PF

The systematic implementation of Acceptance & Commitment Therapy (ACT) in Dutch multidisciplinary chronic pain rehabilitation

Objective This study evaluates the implementation of Acceptance & Commitment Therapy (ACT) in Dutch chronic pain rehabilitation centers. Changes in multidisciplinary professionals’ self-perceived competencies in working with ACT were evaluated and corroborated with patients’ ratings of treatment adherence. To inform subsequent implementation efforts, relevant determinants of implementation success were monitored and the relationship with self-perceived competencies over time was explored. Methods Data was gathered from 111 professionals, 9 managers and 79 patients using questionnaires at the start (T0), halfway (T1) and end (T2) of implementation, and at the end of treatment. Results All professionals adhered to ACT, improved significantly in self-perceived competencies over time and rated competence in working with ACT ≥ adequate at T2. Determinants of success were evaluated extremely positive by professionals and management. Professionals’ self-perceived competencies at T2 were most strongly related to ratings of more workload (b = −.43), and experienced difficulties in working with ACT (b = −.38) at T0 and T1. Conclusion Multidisciplinary chronic pain rehabilitation professionals rated their improvement in working with ACT positively during the implementation period. Impeding and facilitating factors were explored successfully. Practice implications A multi-faceted, long-term, educational, train-the-trainer approach may help to guide systematic changes in multidisciplinary treatmen
