Qualitative analysis of participant experiences during an ecological momentary assessment study of nonsuicidal self-injury among veterans

Ecological momentary assessment (EMA) is a useful tool to investigate antecedents and consequences of nonsuicidal self-injury (NSSI), a robust predictor of Veteran suicide risk. Despite elucidating temporal changes among dynamic variables, EMA remains underutilized to study NSSI among veterans, perhaps due to concerns of safety and utility. The present study analyzed data collected from semi-structured interviews of veterans following a 28-day EMA study of NSSI, including benefits, challenges, and recommendations for improvement. Participants included 34 veterans endorsing NSSI history, most meeting criteria for NSSI Disorder. Qualitative analysis of de-identified transcripts used the rigorous and accelerated data reduction (RADaR) technique and thematic analysis. Findings revealed all veterans reported at least one emotional/social benefit to participation, including finding it therapeutic, gaining self-awareness/insight, and improved social functioning. Challenges and recommendations were primarily technology-related, including adjustment to device use. Many expressed interest in incorporation of clinical resources, use of personal devices/VA app, and ability to share responses with providers. Assessment frequency/content was never described as triggering suicidal/nonsuicidal urges and over half of participants noted urge/behavior reduction. Results support acceptability and safety of EMA for NSSI among veterans and potential clinical utility as a psychotherapy adjunct to promote self-awareness and NSSI reduction.

Multicomponent smoking cessation treatment including mobile contingency management in homeless veterans

INTRODUCTION

Smoking rates are 80% among persons who are homeless, and these smokers have decreased odds of quitting smoking. Little is known about relapse rates among homeless smokers. More information is needed regarding both quit rates and innovative methods to treat smoking cessation among homeless smokers. Web-based contingency management (CM) approaches have been found helpful in reducing smoking among other difficult-to-treat smoker populations but have been generally limited by the need for computers or frequent clinic-based carbon monoxide (CO) monitoring. This open pilot study builds on a web-based CM approach by evaluating a smartphone-based application for CM named mobile CM (mCM). The study was conducted from January 1, 2013-April 15, 2014.

METHOD

Following a 1-week training period, 20 homeless veteran smokers (≥ 10 cigarettes daily for 1 year or more and a CO baseline level ≥ 10 ppm) participated in a multicomponent smoking cessation intervention including 4 weeks of mCM. All smokers received 4 smoking cessation counseling sessions, nicotine replacement, and bupropion (if medically eligible). Participants could earn up to $815 ($480 for mCM, $100 for CO readings showing abstinence [ie, 6 ppm or less] at posttreatment and follow-up, and $35 for equipment return).

RESULTS

Mean compensation for the mCM component was $286 of a possible $480. Video transmission compliance was high during the 1-week training (97%) and the 4-week treatment period (87%). Bioverified 7-day point prevalence abstinence was 50% at 4 weeks. Follow-up bioverified single assessment point prevalence abstinence was 55% at 3 months and 45% at 6 months.

CONCLUSIONS

Results of this open pilot study suggest that mCM may be a useful adjunctive smoking cessation treatment component for reducing smoking among homeless veterans.

Mobile contingency management as an adjunctive smoking cessation treatment for smokers with posttraumatic stress disorder

INTRODUCTION

Smokers with posttraumatic stress disorder (PTSD) smoke at higher prevalence rates and are more likely to relapse early in a quit attempt. Innovative methods are needed to enhance quit rates, particularly in the early quit period. Web-based contingency-management (CM) approaches have been found helpful in reducing smoking among other difficult-to-treat smoker populations but are limited by the need for computers. This pilot study builds on the web-based CM approach by evaluating a smartphone-based application for CM named mobile CM (mCM).

METHODS

Following a 2-week training period, 22 smokers with PTSD were randomized to a 4-week mCM condition or a yoked (i.e., noncontingent 4-week mCM condition). All smokers received 2 smoking cessation counseling sessions, nicotine replacement, and bupropion. Participants could earn up to $690 ($530 for mCM, $25.00 for assessments and office visits [up to 5], and $35.00 for equipment return). The average earned was $314.00.

RESULTS

Compliance was high during the 2-week training period (i.e., transmission of videos) (93%) and the 4-week treatment period (92%). Compliance rates did not differ by group assignment. Four-week quit rates (verified with CO) were 82% for the mCM and 45% for the yoked controls. Three-month self-report quit rates were 50% in the mCM and 18% in the yoked controls.

CONCLUSIONS

mCM may be a useful adjunctive smoking cessation treatment component for reducing smoking among smokers with PTSD, particularly early in a smoking quit attempt.
