A psychological flexibility model of medication adherence in psychotic-spectrum disorders

Attitudes toward and patterns of medication use among people with serious mental illness: There's more than meets the eye

Background and aim

There are growing concerns about the long-term effects of psychiatric medication after a major psychiatric crisis. Recent evidence shows a diverse impact of long-term use on various outcome domains, which may help explain why non-adherence is so common. In the current study we explored the subjective perceptions of factors that impact both attitudes toward and patterns of use of medication among individuals with serious mental illness (SMI).

Method

Sixteen individuals with an SMI and a recognized psychiatric disability who had used psychiatric medication for at least 1 year were recruited for the study via mental health clinics and social media. Participants were interviewed using a semi-structured interview based on the narrative approach, focusing on attitudes toward and patterns of use of psychiatric medication. All interviews were transcribed and analyzed using thematic analysis.

Results

Three discrete sequential phases emerged, each characterized by different themes referring to attitudes toward medication and patterns of use: (1) "loss of self" and a high level of medication use; (2) accumulating experiences of using/reducing/stopping medication; and (3) forming more stable attitudes toward medication and developing one's own pattern of use. The transition between phases was dynamic in nature and represents a non-linear process. Complex interactions were generated at different phases between the related themes, which shaped attitudes toward medication and patterns of use.

Conclusions and implications

The current study reveals the complex ongoing process of forming attitudes toward medication and patterns of use. Recognizing and identifying them via a joint reflective dialog with mental health professionals can enhance alliance, shared decision-making, and person-centered recovery-oriented care.

Using peer-support coaching to improve adherence to online ACT self-help for college mental health: A randomized controlled trial

Online self-help programs such as the Acceptance and Commitment Therapy (ACT) Guide address significant barriers to receiving therapy but suffer from low adherence rates. Peer-delivered coaching, using undergraduate students as coaches, is an innovative alternative to traditional coaching methods which may improve adherence in a more scalable format. To test the efficacy of peer-support coaching for college students using ACT Guide in a naturalistic setting, we conducted a pragmatic randomized controlled trial with three conditions (phone coaching, text message coaching, and a no support control group; N = 230). Participants were block randomized, and program adherence (i.e., number of modules completed) was the primary outcome. Participants completed significantly more ACT Guide modules in phone (M = 7.1, SD = 4.9) and text (M = 5.7, SD = 5) coaching than the no support control condition (M = 1.6, SD = 3.3, p < .001). Participants who received phone coaching experienced significant improvements across almost all measured outcomes as compared to the control group, while participants who received text coaching improved only on some outcomes compared to control (ps < .05). These results support peer-support coaching, particularly when delivered through phone calls, as an efficacious method for improving adherence to and outcomes from online self-help programs.

Influence of Parental Psychological Flexibility on Pediatric COVID-19 Vaccine Hesitancy: Mediating Role of Self-Efficacy and Coping Style

Background: Pediatric COVID-19 vaccine hesitancy hinders the establishment of immune barrier in children. Psychological flexibility may be a key contributing factor to pediatric COVID-19 vaccine hesitancy, and self-efficacy and coping style play an important role in the relationship, but the underlying mechanisms remain unknown.

Methods: A cross-sectional study was conducted on parents from June 2021 to July 2021. A total of 382 parents were recruited for an online-investigation. Serial mediation models were used to examine whether self-efficacy and coping style mediated in the psychological flexibility-pediatric COVID-19 vaccine hesitancy linkage.

Result: Psychological flexibility was negatively related to pediatric COVID-19 vaccine hesitancy (r = −0.198, P < 0.001). Coping styles rather than self-efficacy played a mediating role independently (95% CI: −0.263 to −0.058). Serial mediation analyses indicated that self-efficacy and coping style co-play a serial mediating role in the association of psychological flexibility and pediatric COVID-19 vaccine hesitancy (95% CI: −0.037 to −0.001).

Conclusion: The present study showed that high psychological flexibility, high self-efficacy, and positive coping style were conducive to the lower pediatric COVID-19 vaccine hesitancy.

The Choice Point Model of Acceptance and Commitment Therapy With Inpatient Substance Use and Co-occurring Populations: A Pilot Study

Objectives: Acceptance and Commitment Therapy (ACT) is an empirically supported treatment which aims to enhance self-acceptance and a commitment to core values. The present study examined the effectiveness of the Choice Point model of ACT in a residential substance use disorder (SUD) setting. Choice Point is a contemporary approach to ACT and targets transdiagnostic processes.

Methods: This uncontrolled quasi-experimental design assessed 47 participants taking part in Choice Point for Substances (CHOPS) in order to investigate its influence on psychological inflexibility, values-based action, and self-compassion over time. The study additionally assessed for sleeper effects and associations between transdiagnostic processes and warning signs of relapse.

Results: Findings demonstrated a decrease in psychological inflexibility and increases in values-based action and self-compassion over time. Gains were maintained at follow-up, and sleeper effects were observed for psychological inflexibility and mindfulness. Correlational analysis suggested that all transdiagnostic processes were related to warning signs of relapse at follow-up.

Conclusion: These results provide preliminary evidence for the feasibility, acceptability, and effectiveness of CHOPS for SUD. Observed sleeper effects in psychological inflexibility and mindfulness indicate that CHOPS may provide longer-term benefits critical to a population where relapse is common. While encouraging, these findings should be interpreted with caution. Future research should utilize comparison groups when investigating CHOPS.

Mindfulness-based interventions for medication adherence: A systematic review and narrative synthesis

OBJECTIVE

Inadequate medication adherence is a significant limitation for achieving optimal health outcomes across chronic health conditions. Mindfulness-based interventions (MBIs) have been increasingly applied to promote medical regimen adherence as MBIs have been shown to improve patient-level barriers to adherence (i.e., depressive symptoms, cognitive impairment, stress). The purpose of this review is to investigate the state of research regarding MBIs targeting medication adherence in chronic illnesses and to identify evidence gaps to inform future studies.

METHODS

The search reviewed 5 databases (e.g., PubMed, PsycINFO, Embase, CINAHL, Proquest Thesis/Dissertations) to identify trials that quantitatively evaluated the effect of MBIs on medication adherence. Study abstracts and full texts were screened identifying eligible studies, and findings were summarized using a narrative synthesis.

RESULTS

A total of 497 studies were reviewed; 41 were eligible for full text review and 9 were included in narrative synthesis: seven were RCTs and two were pre-post designs. Study quality varied, with five rated moderate or high risk for bias. Clinical populations tested included living with HIV (k = 3), cardiovascular disease (k = 3), psychological disorders (k = 2), and men who underwent a radical prostatectomy (k = 1). Four studies found significant improvements in medication adherence, however only two of these studies had low risk of bias.

CONCLUSIONS

Research on MBI's for medication adherence is developing, but the effectiveness of MBIs remains unclear due to the nascent stage of evidence and methodological limitations of existing studies. Researchers should prioritize rigorous experimental designs, theory-driven investigations of behavioral mechanisms, and the use of objective measurements of adherence.

An Adaptable Framework for Factors Contributing to Medication Adherence: Results from a Systematic Review of 102 Conceptual Frameworks

OBJECTIVE

To summarize the available conceptual models for factors contributing to medication adherence based on the World Health Organization (WHO)'s five dimensions of medication adherence via a systematic review, identify the patient groups described in available conceptual models, and present an adaptable conceptual model that describes the factors contributing to medication adherence in the identified patient groups.

METHODS

We searched PubMed®, Embase®, CINAHL®, and PsycINFO® for English language articles published from inception until 31 March 2020. Full-text original publications in English that presented theoretical or conceptual models for factors contributing to medication adherence were included. Studies that presented statistical models were excluded. Two authors independently extracted the data.

RESULTS

We identified 102 conceptual models, and classified the factors contributing to medication adherence using the WHO's five dimensions of medication adherence, namely patient-related, medication-related, condition-related, healthcare system/healthcare provider-related, and socioeconomic factors. Eight patient groups were identified based on age and disease condition. The most universally addressed factors were patient-related factors. Medication-related, condition-related, healthcare system-related, and socioeconomic factors were represented to various extents depending on the patient group. By systematically examining how the WHO's five dimensions of medication adherence were applied differently across the eight different patient groups, we present a conceptual model that can be adapted to summarize the common factors contributing to medication adherence in different patient groups.

CONCLUSION

Our conceptual models can be utilized as a guide for clinicians and researchers in identifying the facilitators and barriers to medication adherence and developing future interventions to improve medication adherence.

Investigating the potentially important role of psychological flexibility in adherence to antiretroviral therapy in people living with HIV

Antiretroviral therapy (ART) has significantly improved immune health and survival rates in HIV, but these outcomes rely on near perfect adherence. While many psychosocial factors are related to sub-optimal adherence, effectiveness of associated interventions are modest or inconsistent. The Psychological Flexibility (PF) model underlying Acceptance and Commitment Therapy (ACT) identifies a core set of broadly applicable transdiagnostic processes that may be useful to explain and improve non-adherence. However, PF has not previously been examined in relation to ART adherence. Therefore, this cross-sectional study (n = 275) explored relationships between PF and intentional/unintentional ART non-adherence in people with HIV. Adults with HIV prescribed ART were recruited online. Participants completed online questionnaires assessing self-reported PF, adherence and emotional and general functioning. Logistic regressions examined whether PF processes were associated with intentional/unintentional non-adherence. Fifty-eight percent of participants were classified as nonadherent according to the Medication Adherence Rating Scale, of which 41.0% reported intentional and 94.0% unintentional non-adherence. Correlations between PF and adherence were small. PF did not significantly explain intentional/unintentional non-adherence after controlling for demographic and disease factors. Further clarification of the utility of PF in understanding ART non-adherence is warranted using prospective or experimental designs in conjunction with more objective adherence measures.

Assessing beliefs and attitudes towards antipsychotic medication from a recovery-based perspective: Psychometric properties of a new scale

Antipsychotic medication non-adherence is a complex and multifaceted problem that may hinder recovery in psychosis-spectrum disorders. Therefore, it warrants an early and comprehensive assessment. Current self-report measures focus entirely on behavioral and attitudinal barriers to adherence, failing to provide insight about key psychosocial drivers such as shame and stigma that may also account for non-adherence. This study's main goals were to develop a brief scale for measuring antipsychotic (non)-adherence and associated intra and interpersonal barriers (Antipsychotic Medication Beliefs and Attitudes Scale - AMBAS), and explore its psychometric properties. One hundred and seventy participants with a psychosis-spectrum disorder were recruited and filled in a battery of self-report measures. Exploratory factor analysis supported a two-factor solution, with one factor tapping the influence of different barriers to medication adherence and other factor encompassing perceived positive effects of medication. The scale presented good reliability and convergent validity as evidenced by significant moderate associations with the Medication Adherence Rating Scale. Although in need for further study, AMBAS seems a valid and reliable measure to assess antipsychotic (non)-adherence and underlying behavioral and psychosocial drivers. With replication, AMBAS might be a useful measure that could be used in different clinical and research settings.
