Evaluating the feasibility and acceptability of a mobile-based health technology for smoking cessation: Mobile Anxiety Sensitivity Program

Smartphone-Based Survey and Message Compliance in Adults Initially Unready to Quit Smoking: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Efficacy of smartphone-based interventions depends on intervention content quality and level of exposure to that content. Smartphone-based survey completion rates tend to decline over time; however, few studies have identified variables that predict this decline over longer-term interventions (eg, 26 weeks).

OBJECTIVE

This study aims to identify predictors of survey completion and message viewing over time within a 26-week smoking cessation trial.

METHODS

This study examined data from a 3-group pilot randomized controlled trial of adults who smoke (N=152) and were not ready to quit smoking within the next 30 days. For 182 days, two intervention groups received smartphone-based morning and evening messages based on current readiness to quit smoking. The control group received 2 daily messages unrelated to smoking. All participants were prompted to complete 26 weekly smartphone-based surveys that assessed smoking behavior, quit attempts, and readiness to quit. Compliance was operationalized as percentages of weekly surveys completed and daily messages viewed. Linear regression and mixed-effects models were used to identify predictors (eg, intervention group, age, and sex) of weekly survey completion and daily message viewing and decline in compliance over time.

RESULTS

The sample (mean age 50, SD 12.5, range 19-75 years; mean years of education 13.3, SD 1.6, range 10-20 years) was 67.8% (n=103) female, 74.3% (n=113) White, 77% (n=117) urban, and 52.6% (n=80) unemployed, and 61.2% (n=93) had mental health diagnoses. On average, participants completed 18.3 (71.8%) out of 25.5 prompted weekly surveys and viewed 207.3 (60.6%) out of 345.1 presented messages (31,503/52,460 total). Age was positively associated with overall weekly survey completion (P=.003) and daily message viewing (P=.02). Mixed-effects models indicated a decline in survey completion from 77% (114/148) in the first week of the intervention to 56% (84/150) in the last week of the intervention (P<.001), which was significantly moderated by age, sex, ethnicity, municipality (ie, rural/urban), and employment status. Similarly, message viewing declined from 72.3% (1533/2120) in the first week of the intervention to 44.6% (868/1946) in the last week of the intervention (P<.001). This decline in message viewing was significantly moderated by age, sex, municipality, employment status, and education.

CONCLUSIONS

This study demonstrated the feasibility of a 26-week smartphone-based smoking cessation intervention. Study results identified subgroups that displayed accelerated rates in the decline of survey completion and message viewing. Future research should identify ways to maintain high levels of interaction with mobile health interventions that span long intervention periods, especially among subgroups that have demonstrated declining rates of intervention engagement over time.

An Integrated mHealth App for Smoking Cessation in Black Smokers With HIV: Protocol for a Randomized Controlled Trial

BACKGROUND

Black adults who smoke and have HIV experience immense stressors (eg, racial discrimination and HIV stigma) that impede smoking cessation success and perpetuate smoking-related health disparities. These stressors also place Black adults who smoke and have HIV at an increased risk of elevated interoceptive stress (eg, anxiety and uncomfortable bodily sensations) and smoking to manage symptoms. In turn, this population is more likely to smoke to manage interoceptive stress, which contributes to worse HIV-related outcomes in this group. However, no specialized treatment exists to address smoking cessation, interoceptive stress, and HIV management for Black smokers with HIV.

OBJECTIVE

This study aims to test a culturally adapted and novel mobile intervention that targets combustible cigarette smoking, HIV treatment engagement and adherence, and anxiety sensitivity (a proxy for difficulty and responsivity to interoceptive stress) among Black smokers with HIV (ie, Mobile Anxiety Sensitivity Program for Smoking and HIV [MASP+]). Various culturally tailored components of the app are being evaluated for their ability to help users quit smoking, manage physiological stress, and improve health care management.

METHODS

This study is a pilot randomized controlled trial in which Black combustible cigarette smokers with HIV (N=72) are being recruited and randomly assigned to use either (1) the National Cancer Institute's QuitGuide app or (2) MASP+. Study procedures include a web-based prescreener; active intervention period for 6 weeks; smartphone-based assessments, including daily app-based ecological momentary assessments for 6 weeks (4 ecological momentary assessments each day); a video-based qualitative interview using Zoom Video Communications software at week 6 for participants in all study conditions; and smartphone-based follow-up assessments at 0, 1, 2 (quit date), 3, 4, 5, 6, and 28 weeks postbaseline (26 weeks postquitting date).

RESULTS

Primary outcomes include biochemically verified 7-day point prevalence of abstinence, HIV-related quality of life, use of antiretroviral therapy, and HIV care appointment adherence at 26 weeks postquitting date. Qualitative data are also being collected and assessed to obtain feedback that will guide further tailoring of app content and evaluation of efficacy.

CONCLUSIONS

The results of this study will determine whether the MASP+ app serves as a successful aid for combustible cigarette smoking cessation, HIV treatment engagement, and physiological stress outcomes among Black people with HIV infection. If successful, this study will provide evidence for the efficacy of a new means of addressing major mental and physical health difficulties for this high-risk population. If the results are promising, the data from this study will be used to update and tailor the MASP+ app for testing in a fully powered randomized controlled trial that will evaluate its efficacy in real-world behavioral health and social service settings.

Best Practices for Developing a Diabetes mHealth App

The widespread use of smartphones in the United States has led to a surge in mHealth apps designed to support people with various health issues. Yet the effectiveness and long-term impacts of these apps still need to be determined. This article presents a case study of the development of MyT1DHero, an mHealth app for people with type 1 diabetes, to identify best practices for app development. We propose four essential best practices based on the insights gained from this case study: incorporating theoretical frameworks, prioritizing user feedback, engaging key stakeholders, and establishing a robust data-collection foundation. These findings have practical implications for researchers and developers seeking to create effective mHealth interventions. Furthermore, we suggest future research directions to advance the development and implementation of innovative health technologies.

Anxiety sensitivity in terms of mental health among a racially and ethnically diverse sample of sexual minority college students

Objective: Limited work has focused on understanding the function of individual difference factors in terms of mental health among sexual minority college students. Anxiety sensitivity is one individual difference factor which has received substantial empirical attention, but its role is presently understudied among racially/ethnically diverse sexual minority college students.Participants: Participants included a racially and ethnically diverse sample of sexual minority college students (N = 217; Mage = 20.82 years; SD = 3.06).Methods: The present investigation evaluated the role of anxiety sensitivity in relation to anxious arousal, social anxiety, depression, and suicidality.Results: Results indicated that anxiety sensitivity was significantly related to increased anxious arousal, social anxiety, depression, and suicidality after adjusting for age, sex, relationship status, subjective social status, and neuroticism.Conclusions: This investigation provides the first empirical evidence that anxiety sensitivity is related to poorer mental health outcomes for racially/ethnically diverse sexual minority college students.

Life's essential eight as targets for cardiometabolic risk reduction among non-Hispanic black adults: A primary care approach

Cardiovascular diseases remain the leading cause of death in the United States. Several studies have shown racial disparities in the cardiovascular outcomes. When compared to their Non-Hispanic White (NHW) counterparts, non-Hispanic Black (NHB) individuals have higher prevalence of cardiovascular risk factors and thus, increased mortality from atherosclerotic cardiovascular diseases. This is evidenced by lower scoring in the indices of the American Heart Association's Life Essential 8 among NHB individuals. NHB individuals score lower in blood pressure, blood lipids, nicotine exposure, sleep, physical activity level, glycemic control, weight, and diet when compared to NHW individuals. Measures to improve these indices at the primary care level may potentially hold the key in mitigating the health care disparities in cardiovascular health experienced by NHB individuals.

Anxiety Sensitivity Among Non-Hispanic Black Adults: Relations to Mental Health and Psychosomatic States

The non-Hispanic Black adult population has notable disparities in mental and physical health compared to several other racial/ethnic groups. Yet, there is a lack of scientific knowledge about psychologically based individual difference factors that may be associated with an exacerbation of common mental and physical health symptoms among non-Hispanic Black persons. The present investigation sought to build on the limited knowledge about anxiety sensitivity among non-Hispanic Black adults by exploring whether this construct was uniquely associated with a range of prevalent mental health and psychosomatic symptoms commonly tied to disparities among this population. Participants included non-Hispanic Black adults (N = 205; Mage = 21.67 years; SDage = 5.39; age range: 18-60 years; 82.0% female). Results indicated that anxiety sensitivity was positively related to anxious arousal, general depression, insomnia, fatigue severity, and somatic symptom severity; effects were evident above and beyond the variance explained by a range of covariates, including age, sex, education, subjective social status, and neuroticism. Overall, the present findings uniquely build from past research on anxiety sensitivity and non-Hispanic Black adults by demonstrating that individual differences in this construct are consistently and relatively robustly associated with a wide range of mental health and psychosomatic symptoms. Future research that builds from this work may benefit from consideration of intervention programming targeting anxiety sensitivity reduction to offset mental and physical health impairments among the non-Hispanic Black population.

A Smartphone-Based Intervention for Anxiety and Depression in Racially and Ethnically Diverse Adults (EASE): Protocol for a Randomized Controlled Trial

BACKGROUND

Clear health disparities have emerged in the rates of COVID-19 exposure, hospitalization, and death among Black, Hispanic, and American Indian (BHAI) individuals, relative to non-Hispanic White (NHW) individuals. BHAI populations have been disproportionately affected by lower behavioral health access and heightened negative mental health outcomes during the pandemic.

OBJECTIVE

This project directly addresses health disparities in access to behavioral health care during the COVID-19 pandemic among BHAI populations via an adaptation of the established, initially validated, low-cost, mobile app Easing Anxiety Sensitivity for Everyone (EASE) among individuals with symptoms of elevated anxiety or depression or both.

METHODS

The EASE trial is a 2-arm, prospective, randomized, blinded-assessor study with intention-to-treat analysis. Participants (N=800; n=200, 25%, Black; n=200, 25%, Hispanic; n=200, 25%, American Indian; and n=200, 25%, NHW) are randomized to receive either EASE or an active comparison condition for anxiety and depression. Participants compete an online prescreener, an enrollment call to provide informed consent, a baseline survey, a 6-month intervention period, and 3- and 6-month postbaseline assessments. Select participants also complete a 3- and 6-month postbaseline qualitative interview via phone or an online platform (eg, Zoom). Participants complete 2 scheduled daily ecological momentary assessments (EMAs) during the 6-month study period. These twice-daily EMAs guide a just-in-time approach to immediate, personalized behavioral health care.

RESULTS

Outcomes include reductions in anxiety and depressive symptoms and functional impairment at 3 and 6 months postrandomization. We also will examine putative mechanisms (eg, anxiety sensitivity [AS] and COVID-19-specific stress and fear) of the intervention effects. Further, as treatment effects may differ across sociocultural factors, perceived discrimination, social support, and socioeconomic status (SES) will be evaluated as potential moderators of treatment effects on the primary outcomes. Process evaluation using data collected during the study, as well as individual interviews with participants, will complement quantitative data.

CONCLUSIONS

Data from this efficacy trial will determine whether EASE successfully improves symptoms of anxiety and depression and whether these improvements outperform an active comparison control app. If successful, findings from this study have the potential to decrease anxiety and depression symptoms among vulnerable populations determined to be most at risk of exacerbated, long-lasting negative health sequelae. Data from this study may be used to support an implementation and dissemination trial of EASE within real-world behavioral health and social service settings.

Anxiety sensitivity in relation to post-traumatic stress disorder symptom clusters among young adults with probable post-traumatic stress disorder

Despite the promise of past research on anxiety sensitivity (AS) and posttraumatic stress, extant work is limited, given (1) most studies consist of non-Hispanic White and middle-aged samples, (2) few have demonstrated incremental validity to general emotional traits and social determinants of health, and (3) limited work has characterized how AS relates to specific Posttraumatic Stress Disorder (PTSD) symptom clusters among those with (probable) PTSD. The current study evaluated the role of AS in relation to PTSD symptom clusters among a racially/ethnically diverse sample of young adults with probable PTSD. Participants included young adults who met the clinical cut-off for probable PTSD per the Posttraumatic Diagnostic Scale. Results indicated that AS was significantly related to overall posttraumatic stress symptom severity; the effect was evident after adjusting for a range of covariates including neuroticism and subjective social status. AS also was incrementally associated with arousal and hyperreactivity, changes in mood and cognition, and intrusion PTSD symptom clusters. In contrast to expectation, no effect for AS was evident for the avoidance PTSD symptom cluster. The current data uniquely add to the existing AS PTSD literature by showcasing distinct symptom cluster patterns among a racially/ethnically diverse sample of young adults with probable PTSD.

Anxiety sensitivity and its association with perceived barriers for quitting, smoking inflexibility, and severity of quit problems among Black smokers

Black individuals who smoke in the United States experience health disparities related to tobacco use (e.g., greater nicotine dependence, less success in quitting smoking) and interoceptive distress (e.g., somatic symptoms, anxiety). Individual difference factors that amplify interoceptive distress and contribute to poorer smoking behaviors and outcomes warrant further attention and investigation. Thus, the present study sought to explore the association between anxiety sensitivity and clinically-relevant smoking variables of perceived barriers for quitting, smoking inflexibility, and problems experienced during past quit attempts. Participants in the current study included 98 Black adult smokers (71.4% male; Mage = 44.08 years, SD = 11.44 years). Results indicated greater levels of anxiety sensitivity were associated with greater levels of perceived barriers for quitting smoking (b = 0.10, SE = 0.08, p = 0.01), smoking inflexibility (b = 0.02, SE <.001, p <.001), and problems experienced during past smoking quit attempts (b = 0.17, SE = 0.07, p = 0.02). Clinical implications and future directions are further discussed as it relates to anxiety sensitivity and efforts to reduce or quit smoking for this health disparities population.

An Integrated mHealth App for Smoking Cessation in Black Smokers With Anxiety: Protocol for a Randomized Controlled Trial

BACKGROUND

Black smokers have greater difficulty in quitting and higher rates of smoking-related diseases and disabilities than the general population. The smoking disparities experienced by this group are, in part, a consequence of multiple chronic life stressors (eg, racial discrimination) that engender increased exposure to interoceptive stress symptoms (eg, anxiety), which can ultimately lead to smoking as a means of immediate emotion regulation.

OBJECTIVE

This study aimed to culturally adapt and initially test a novel mobile intervention (ie, Mobile Anxiety Sensitivity Program for Smoking [MASP]) that targets anxiety sensitivity (AS; a proxy for difficulty and responsivity to interoceptive stress) among Black smokers. The MASP intervention is culturally informed to address interoceptive stress management difficulties among Black smokers and is thus hypothesized to facilitate smoking cessation.

METHODS

In phase 1, a total of 25 Black smokers with elevated AS will be administered MASP for 6 weeks. Following the completion of phase 1, we will further refine the MASP based on qualitative and quantitative data from participants to produce the final MASP iteration. In phase 2, a total of 200 Black smokers with elevated AS will be enrolled and randomly assigned to receive nicotine replacement therapy and either the smartphone-based National Cancer Institute QuitGuide app for standard mobile smoking cessation treatment or the MASP intervention. All participants in phases 1 and 2 will be enrolled remotely and will complete a web-based study screener; smartphone-based baseline assessment; daily smartphone-based ecological momentary assessments for 6 weeks; phone-based end-of-treatment qualitative interviews; and smartphone-based follow-up assessments at postbaseline weeks 1, 2 (quit date), 3, 4, 5, 6, 28, and 54 (weeks 28 and 54 follow-ups will be completed by phase 2 participants only). The MASP intervention is intended to offset barriers to treatment and encourage treatment engagement via smartphones.

RESULTS

This project was funded in September 2020. Phase 1 data collection began in January 2022. Phase 2 data collection is scheduled to begin in July 2022.

CONCLUSIONS

If successful, data from this study will support culturally informed treatment approaches for Black smokers and, pending findings of efficacy, provide an evidence-based mobile intervention for smoking cessation that is ready for dissemination and implementation.

Feasibility and acceptability of experience sampling among LGBTQ+ young people with self-harmful thoughts and behaviours

This study was the first to determine whether it was feasible and acceptable to use experience sampling methods (ESM) among LGBTQ+ young people, who had current experiences of self-harm. Sixteen LGBTQ+ young people (16-25 years old) took part in the experience sampling study. This included a baseline assessment, a 7-day ESM assessment (participants were sampled six times a day using a phone app), and the option of an interview at the end of the 7-day ESM assessment. Feasibility data was descriptively analysed, with pilot ESM data presented. Qualitative data was thematically analysed to determine the acceptability (barriers and facilitators) of taking part in this study. Study feasibility was assessed by enrolment rate (55.2%), participant retention across assessment period (100%), ESM app feasibility (87.5%), and good adherence to total number of ESM surveys (67.6%). Individual study adherence ranged between 43 and 95.2%. Study acceptability was assessed by participant interviews. Thematic analysis indicated four superordinate themes; (i) Self-reflection and awareness; (ii) Practicalities of ESM surveys; (iii) Daily timeframes; and (iv) Suggestions for future studies. Pilot ESM data demonstrates that there was fluctuation of depressive and anxiety symptoms within- and between- participants over the course of the study, however, greater sample power is needed for full analysis. This study demonstrated that ESM designs are feasible and acceptable among LGBTQ+ young people with current experiences of self-harm. Pilot data indicated that specific experiences and moods are likely to be important to self-harm. These potentially have a temporal influence on self-harm behaviour or ideation, and therefore should be examined in a fully powered sample.

mHealth and technology innovations for anxiety and OC spectrum disorders

Interdisciplinary mobile health (mHealth) technologies and intervention approaches are changing the nature of health research, providing the opportunity to shift from more reactive approaches for patient care to a more proactive stance. As with the larger field of medicine, mHealth and technology-enhanced approaches in psychiatry and clinical psychology are opening an unparalleled number of avenues to help reduce the risk for psychiatric disease, treat psychological disorders, and increase well-being of our patients. While promising, this research is characterized by complex challenges across the domains of concept development, initial design and testing, and downstream implementation and scaled-up dissemination. This Special Issue in the British Journal of Clinical Psychology was designed to highlight the development and implementation of mHealth research in the anxiety and obsessive-compulsive spectrum disorders. In addition to informing readers about important advances that have been made, the present special issue also draws attention to the myriad challenges that will need to be considered in future research. Three domains relevant for mHealth research are addressed, including a careful consideration of where the research currently stands and what challenges we should prepare for, the adaptation of traditional and adjunctive treatments to mobile or online platforms, and the ability for technology and associated methodological approaches to provide further insight into aetiological investigations.
