- Social withdrawal is a well-established part of sickness behavior, but in some contexts sick animals might gain from keeping close instead of keeping away. For instance, sick individuals are more willing to be near known individuals who can provide care and safety (close others) compared to when healthy. Yet, interactions with some strangers might also be beneficial (i.e., healthcare professionals), but it is not known how sickness interplay with social behavior towards such individuals. Here, we assessed if sickness affects perception of caregivers, and developed a new task, the Caregiver Perception Task (CgPT). Twenty-six participants performed the CgPT, once after an injection of lipopolysaccharide (LPS, 0.8 ng/kg body weight, n = 24), and once after an injection of saline (n = 25), one hour and forty-five minutes post-injection. During the task, participants watched short video clips of three types of caregivers: a healthcare professional taking care of a sick individual, a healthcare professional not taking care of a sick individual, and a non-healthcare professional taking care of their sick adult child or partner. After each video clip, the likability, trustworthiness, professionalism, and willingness to interact with and receive care from the caregiver were rated on visual analogue scales. Results showed that participants injected with saline rated healthcare professionals who did not take care of a sick individual less positively on all aspects compared to healthcare professionals who took care of a sick individual. Moreover, compared to saline, LPS increased the participants’ willingness to receive care from healthcare professionals and non-healthcare professionals providing care, but not from healthcare professionals not providing care. Thus, our results indicate that sick individuals may approach unknown individuals with potential to provide care and support.

- According to cognitive-behavioral models of social anxiety disorder (SAD), four of the important maintaining mechanisms are avoidance, self-focused attention, anticipatory processing and post-event cognitive processing. Individual cognitive therapy (ICT) and cognitive behavioral group therapy (CBGT) both have substantial empirical support. However, it is unclear whether they achieve their effects by similar or different mechanisms. The aim of this study was to investigate whether changes in the four maintenance processes mediate clinical improvement in la and CBGT for SAD. We analyzed data from participants (N = 94) who received either ICT or CBGT in two separate RCTs. The results showed that ICT had larger effects than CBGT on social anxiety and each of the four potential mediators. More pertinently, moderated mediation analyses revealed significant between-treatment differences. Whereas improvement in ICT was mainly mediated by reductions in avoidance and self-focused attention, improvement in CBGT was mediated by changes in self-focused attention and in anticipatory and post-event processing. These results support the importance of the putative mediators, but suggest that their relative weights are moderated by treatment type.

- OBJECTIVE: A sudden gain is defined as a large and stable individual improvement occurring between two consecutive treatment sessions. Sudden gains have been shown to predict better long-term improvement in several treatment studies, including cognitive behavioural therapy for depression and anxiety disorders, but have not been studied in the treatment of health anxiety or any form of internet-based cognitive behavioural therapy. The aim of this study was to investigate the role of sudden gains in internet-based cognitive behavioural therapy for severe health anxiety.METHOD: We examined the occurrence and significance of sudden gains in measures of health anxiety in 81 participants receiving internet-based cognitive behavioural therapy. We compared patients with sudden gains, patients without sudden gains, and patients with gradual gains.RESULTS: Thirteen participants (16%) experienced one sudden gain in health anxiety with individual sudden gains distributed across the treatment. As expected, patients with a sudden gain showed larger improvements than patients without a sudden gain at post-treatment (d = 1.04) and at one-year follow-up (d = 0.91) on measures of health anxiety.CONCLUSIONS: Consistent with previous studies, sudden gains in internet-based cognitive behavioural therapy are associated with significantly larger and stable treatment effects up to one-year follow-up.

- BACKGROUND: The utility of cognitive behavioural (CB) interventions for chronic pain has been supported in numerous studies. This includes Acceptance and Commitment Therapy (ACT), which has gained increased empirical support. Previous research suggests that improvements in pain catastrophizing and psychological inflexibility are related to improvements in treatment outcome in this type of treatment. Although a few studies have evaluated processes of change in CB-interventions, there is a particular need for mediation analyses that use multiple assessments to model change in mediators and outcome over time, and that incorporate the specified timeline between mediator and outcome in the data analytic model.METHODS: This study used session-to-session assessments to evaluate if psychological inflexibility, catastrophizing, and pain intensity mediated the effects of treatment on pain interference. Analyses were based on data from a previously conducted randomized controlled trial (n = 60) evaluating the efficacy of ACT and Applied Relaxation (AR). A moderated mediation model based on linear mixed models was used to analyse the data.RESULTS: Neither catastrophizing nor pain intensity mediated changes in pain interference for any of the treatments. In contrast, psychological inflexibility mediated effects on outcome in ACT but not in AR.CONCLUSIONS: Results add to previous findings illustrating the role of psychological inflexibility as a mediator in ACT.
