In 2023, it was estimated that 76.4% of adults (129 million) in the United States (US) were living with a chronic health condition (CHC) such as heart disease, diabetes, and chronic pain, among oth...

Living with a chronic health condition (CHC) can negatively impact quality of life (QoL) through a complex interaction of mental health challenges, functional limitations, and disease management demands. Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach that shows promise in addressing shared challenges across various CHCs by fostering psychological flexibility (PF). PF has been associated with improved QoL and functional outcomes and reduced psychological symptoms in individuals living with specific CHCs; yet its mediating role in these outcomes remains underexplored. This secondary analysis examined whether changes in PF mediated improvements in QoL, psychological symptoms, and functional impairment among individuals with various CHCs. Participants (n = 100) were randomized to a six-session self-guided, online ACT program or a waitlist control group. Outcomes were assessed at baseline, post-treatment, and four-week follow-up. Results revealed that increases in PF significantly mediated improvements in QoL, with indirect effects indicating that higher PF at post-treatment predicted better QoL at follow-up. The ACT group demonstrated significant reductions in functional impairment at follow-up compared to the waitlist group, though this effect was not mediated by changes in PF. Improvements in psychological symptoms were not statistically significant and were not mediated by PF. These findings suggest that ACT effectively enhances PF, which subsequently improves QoL in individuals with CHCs. This supports the transdiagnostic applicability of ACT for improving mental health and QoL across diverse chronic conditions. Future research should explore additional mechanisms underlying ACT's effects and investigate ways to optimize its impact on functional and psychological outcomes within CHCs.

Those with eating disorders (EDs) characterized by purging behaviors tend to show more impulsivity than those diagnosed with restrictive eating, who tend to show more compulsivity. Impulsive choice (i.e. a type of impulsivity) is a common factor among eating disorders that is less understood. Delay discounting is a measure of choice impulsivity, examining the decrease in value of delayed outcomes. In this exploratory study, we examined associations between eating disorder type, age and delay discounting among patients at a residential ED treatment center (N = 178). Our findings showed that those diagnosed with bulimia nervosa had higher delay discounting (i.e. more impulsivity) at intake compared to anorexia nervosa, binge eating disorder, and other eating types but there were no significant differences. Those diagnosed with bulimia nervosa, as well as those with ARFID and unspecified ED showed a preference for delayed rewards at discharge, but there were no significant differences among ED types. Moderation analyses showed that age, ED type, nor the interaction did not significantly predict delay discounting at intake or discharge. To conclude, those with bulimia nervosa demonstrate less impulsive choice at discharge from a residential ED treatment center. However, additional research is needed given the variability of sample sizes in this study.

Trichotillomania, also known as Hair-Pulling Disorder, is characterized by recurrent pulling out of one’s hair over brief episodes or sustained periods of time and results in hair loss. ACT-enhanced behavior therapy (A-EBT) has been shown to be an effective approach in the treatment of trichotillomania by promoting psychological flexibility around hair pulling urges and teaching stimulus control and habit reversal training. However, there is limited support of A-EBT for clients with an ethnic minority identity. This case report focuses on an adult, Hispanic female client, Luna (pseudonym), who received eight sessions of A-EBT for the treatment of trichotillomania. At post-treatment, Luna showed significant improvements in number of hairs pulled, trichotillomania specific psychological flexibility, depression and anxiety. Luna’s case highlights barriers to care such as potential resistance in seeking mental health services, the influence of family members’ beliefs on receiving mental health services, and the limited access to specialized treatment of trichotillomania.

Depression is most often treated in primary care, where the prevailing treatment is antidepressant medication. Primary care patients with depression are less likely to be exposed to psychosocial interventions, despite evidence suggesting many of these treatments are effective. An example is acceptance and commitment therapy (ACT), a behavioral treatment for depression with a growing evidence base. A self-guided ACT intervention with a peer narrative (i.e. storytelling) format was developed with the intention of creating a treatment option for primary care patients that was more accessible than traditional psychotherapy. Titled LifeStories, the online program features videos of real individuals sharing coping skills for depression based on lived experiences and key ACT principles. A total of 93 primary care patients taking antidepressants were randomized to either continued antidepressant treatment alone or antidepressant treatment plus LifeStories for 4 weeks. There were no differences over time on depression severity and psychological inflexibility. However, LifeStories led to greater improvements in quality of life and increased patients' interest in additional treatment compared to antidepressant medication alone.Clinical trial pre-registration: ClinicalTrials.gov (NCT04757961).

Given the broad benefits of physical activity (PA) but low PA levels among breast cancer survivors (i.e., women who have received a breast cancer diagnosis), innovative and evidence-based techniques are needed to motivate and support exercise. This study systematically reviews the use of behavior change techniques (BCTs) in digital PA interventions for breast cancer survivors. Studies were retrieved from five electronic databases and were included if they (i) sampled exclusively female breast cancer survivors aged >18 years, (ii) involved a digital intervention with the primary purpose of increasing PA, (iii) included a BCT component, (iv) used a randomized or quasi-randomized design, and (v) were published from January 2000 to May 2022. Two coders independently extracted data. Twenty primary studies met the inclusion criteria and were included in this review. All interventions used at least one BCT (mean 4 ± 1, range 2–13); self-monitoring (85%) and goal setting (79%) were the most common BCTs. Twelve of 20 (60%) studies reported improvements in PA behavior in the intervention vs. control group, and self-monitoring and goal setting were the most commonly used BCTs in these studies. Of the 93 total BCTs, 66 were not used in any interventions in the review, including critical constructs for PA behavior change (e.g., biofeedback). BCTs, important facilitators of PA behavior change, are being underutilized in digital PA interventions for breast cancer survivors. Future research should incorporate more diverse BCTs to explore if they can add to the effectiveness of digital interventions for this population.
