An experimental investigation of reactivity to ecological momentary assessment frequency among adults trying to quit smoking.

ABSTRACT: AIMS:Ecological Momentary Assessment (EMA) captures real-time reports in subjects' natural environments. This experiment manipulated EMA frequency to estimate effects on abstinence and peri-cessation subjective experiences. DESIGN:In this randomized trial, subjects had an equal chance of being assigned to low-frequency (once) or high-frequency (six times) daily EMA for 4?weeks (1?week pre- and 3?weeks post-cessation). Participants completed six office visits over 5?weeks and 6- and 12-week follow-up telephone interviews. SETTING:Community participants were recruited from central New Jersey, USA. PARTICIPANTS:One hundred and ten adult daily smokers seeking to quit smoking were included in intent-to-treat analyses of tobacco abstinence; 94 were available for secondary analyses of peri-cessation subjective ratings. MEASUREMENTS:Primary outcomes were cessation (abstaining at least 24?hours within 2?weeks of attempting to quit) and prolonged abstinence (no relapse between weeks 2 and 12 post-quit). Secondary outcomes were mean levels and growth in ratings of cigarette craving, affect and quitting motivation and self-efficacy. FINDINGS:EMA frequency was unrelated to cessation (odds ratio?=?1.367, 95% confidence interval?=?0.603-3.098) or prolonged abstinence (odds ratio?=?1.040, 95% confidence interval?=?0.453-2.388) in intent-to-treat analyses. High-frequency EMA was associated with lower craving (B?=?-0.544, standard error (SE)?=?0.183, P?=?0.004, anxiety (B?=?-0.424, SE?=?0.170, P?=?0.015), anger (B?=?-0.474, SE?=?0.139, P?=?0.001), hunger (B?=?-0.388, SE?=?0.170, P?=?0.025) and positive affect (B?=?-0.430, SE?=?0.196, P?=?0.03). CONCLUSIONS:In smokers trying to quit, more frequent ecological momentary assessment self-monitoring results in lower craving, anxiety, anger, hunger and positive affect. It is not clear whether this translates into higher rates of smoking abstinence.

Project description:AIMS:To assess whether individuals trying to quit smoking who have high depressive symptoms (HD), compared with low depressive symptoms (LD): (1) report more frequent stressful events (SEs), (2) are more likely to smoke after SEs, (3) experience greater acute or persistent changes in affect after an SE, and (4) are at greater risk of smoking following affective changes. DESIGN:Smoking cessation data were analyzed using multi-level path modeling to examine the moderating effects of depressive symptoms on relations among SEs, subsequent affect, and smoking. SETTING:An academic research center in Central New Jersey, USA. PARTICIPANTS:Seventy-one adult treatment-seeking daily smokers recruited from 2010 to 2012. MEASUREMENTS:Baseline depressive symptoms [HD: Center for Epidemiological Studies Depression Scale (CES-D) ? 16 versus LD: CES-D < 16]; and real-time ecological momentary assessment (EMA) reports of SEs, affect, and smoking assessed during 21 days post-quit. FINDINGS:Multi-level models indicated that HD smokers were more likely than LD smokers to report stressful events [odds ratio (OR) = 2.323, P = 0.009], but had similar post-stress acute affective changes (negative affect: b = -0.117, P = 0.137, positive affect: b = 0.020, P = 0.805). Only HD smokers reported increased negative affect (NA) (b = 0.199, P = 0.030) and decreased positive affect (PA) up to 12 hours later (b = -0.217, P = 0.021), and greater lapse risk up to 24 hours after an SE (OR = 3.213, P = 0.017). The persistence of elevated NA and suppressed PA was partially explained by increased odds of subsequent SEs among HD smokers. However, the heightened stress-lapse association over 24 hours found in HD smokers was not fully explained by sustained aversive affect or subsequent SEs. CONCLUSIONS:Depressed and non-depressed smokers trying to quit appear to experience similar acute affective changes following stress: however, depressed smokers experience higher rates of exposure to stress, longer-lasting post-stress affective disturbance and greater risk of smoking lapse 12-24 hours after a stressful event than non-depressed smokers.

Project description:BackgroundEcological momentary assessment (EMA) is an increasingly used tool for data collection in behavioral research, including smoking cessation studies. As previous addiction research suggests, EMA has the potential to elicit cue reactivity by triggering craving and increasing behavioral awareness. However, there has been limited evaluation of its potential influence on behavior.ObjectiveBy examining the perspectives of research participants enrolled in a tobacco treatment intervention trial, this qualitative analysis aims to understand the potential impact that EMA use may have had on smoking behaviors that may not have otherwise been captured through other study measures.MethodsWe performed a qualitative analysis of in-depth interviews with participants enrolled in a pilot randomized controlled trial of a tobacco treatment intervention that used SMS text messaging to collect EMA data on smoking behaviors. In the pilot randomized controlled trial, combustible cigarette and e-cigarette use and smoking-related cravings were measured as part of an EMA protocol, in which SMS text messaging served as a smoking diary. SMS text messaging was intended for data collection only and not designed to serve as part of the intervention. After a baseline assessment, participants were asked to record daily nicotine use for 12 weeks by responding to text message prompts that they received 4 times per day. Participants were prompted to share their experiences with the EMA text messaging component of the trial but were not directly asked about the influence of EMA on their behaviors. Transcripts were coded according to the principles of the framework for applied research. The codes were then examined, summarized, and grouped into themes based on the principles of grounded theory.ResultsInterviews were analyzed for 26 participants. The themes developed from the analysis suggested the potential for EMA, in the form of an SMS text messaging smoking diary, to influence participants' smoking behaviors. The perceived impacts of EMA text messaging on smoking behaviors were polarized; some participants emphasized the positive impacts of text messages on their efforts to reduce smoking, while others stressed the ways that text messaging negatively impacted their smoking reduction efforts. These contrasting experiences were captured by themes reflecting the positive impacts on smoking behaviors, including increased awareness of smoking behaviors and a sense of accountability, and the negative impacts on emotions and smoking behaviors, including provoking a sense of guilt and triggering smoking behaviors.ConclusionsThe collection of EMA smoking behavior data via SMS text messaging may influence the behaviors and perceptions of participants in tobacco treatment interventions. More research is needed to determine the magnitude of impact and mechanisms, to account for the potential effects of EMA. A broader discussion of the unintended effects introduced by EMA use is warranted among the research community.
