Systematic Review of Acceptance and Commitment Therapy in Individuals with Neurodevelopmental Disorders, Caregivers, and Staff

Acceptance and Commitment Therapy (ACT) for people with advanced progressive illness, their caregivers and staff involved in their care: A scoping review

BACKGROUND

People with an advanced progressive illness and their caregivers frequently experience anxiety, uncertainty and anticipatory grief. Traditional approaches to address psychological concerns aim to modify dysfunctional thinking; however, this is limited in palliative care, as often concerns area valid and thought modification is unrealistic. Acceptance and Commitment Therapy is a mindfulness-based behavioural therapy aimed at promoting acceptance and valued living even in difficult circumstances. Evidence on its value in palliative care is emerging.

AIMS

To scope the evidence regarding Acceptance and Commitment Therapy for people with advanced progressive illness, their caregivers and staff involved in their care.

DESIGN

Systematic scoping review using four databases (Medline, PsychInfo, CINAHL and AMED), with relevant MeSH terms and keywords from January 1999 to May 2023.

RESULTS

1,373 papers were identified and 26 were eligible for inclusion. These involved people with advanced progressive illness (n = 14), informal caregivers (n = 4), palliative care staff (n = 3), bereaved carers (n = 3), and mixed groups (n = 2). Intervention studies (n = 15) showed that Acceptance and Commitment Therapy is acceptable and may have positive effects on anxiety, depression, distress, and sleep in palliative care populations. Observational studies (n = 11) revealed positive relationships between acceptance and adjustment to loss and physical function.

CONCLUSION

Acceptance and Commitment Therapy is acceptable and feasible in palliative care, and may improve anxiety, depression, and distress. Full scale mixed-method evaluation studies are now needed to demonstrate effectiveness and cost-effectiveness amongst patients; while further intervention development and feasibility studies are warranted to explore its value for bereaved carers and staff.

Online ACT Matrix Parent Training for Japanese-Speaking Mothers with Distress in the United States

Cultural stigma, shame, self-concealment, and language and socio-economic barriers often keep Asian immigrant parents and children away from mental and behavioral services in the United States. Research shows that increased levels of parent distress suggest a negative impact on parenting practices and correlate child-maltreatment. Therefore, this study aimed to test one functionally contextual strategy to address such issues. The current study evaluated the effects of an online Acceptance and Commitment Training (ACT) Matrix for Japanese-speaking mothers living the United States. A nonconcurrent multiple baseline single-subject design across four mothers was used to assess the effect of ACT Matrix on value-driven behaviors, parental engagement (session attendance and daily assignment completion), parental distress, and psychological flexibility. The study consisted of a baseline, treatment (three ACT Matrix treatment sessions adapted from the six-step protocol), maintenance, and follow-up phases. A visual analysis reporting level, trend, variability, immediacy of change and overlap was used to identify a functional relation between the treatment and observable overt behaviors of value-driven behaviors and daily assignment completion. In addition, a non-overlap of all pairs was used to measure effect sizes for these behaviors. For psychological flexibility and parental distress, we used the reliable change index to assess whether clinically significant improvement occurred or not. The results revealed that the online ACT Matrix parent training program was effective in improving all four dependent variables. Mothers reported that the training was culturally sensitive, effective, and acceptable. The details of findings and the implications for future research as preventive science are discussed.

Effects of Acceptance and Commitment Training Plus Behavior Parent Training on Parental Implementation of Autism Treatment

The objective of this study was to examine the effects of acceptance and commitment training (ACT) plus behavior parent training (BPT), when delivered via telehealth, on parental implementation of behavioral strategies, experiential avoidance (EA), and stress. The study also examined the subsequent effects on the parents’ autistic children’s behaviors. A multiple baseline design was implemented across four parent-child dyads who participated in the online training. The findings showed that ACT+BPT resulted in parental implementation reaching and maintaining high levels. The training also decreased EA and stress in three parents. Moreover, the parents’ ratings of their children’s challenging behaviors decreased. However, such a trend was not as clearly depicted by direct measures of the children’s behaviors. A social validity interview revealed parents found ACT beneficial in assisting them to learn and use the BPT strategies. Implications and suggestions for future research are discussed.
